Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments These are part of the embodiments of this application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

As shown in Figures 1 to 3, the embodiment of the present application proposes a speaker 1 in a first aspect, which includes: a resonant body 12 configured to vibrate according to the audio current; the speaker 1 has an adsorption surface 13. The adsorption surface 13 is provided on one side of the resonant body 12 .

The speaker 1 also includes a voice coil 11, which is configured to be supplied with audio current to generate vibration; a resonant body 12 is attached to one side of the voice coil 11 and resonates with the voice coil 11; an adsorption surface 13 is provided at the resonance The side of body 12 facing away from voice coil 11.

Based on the above technical solution, in this speaker 1, the resonant body 12 is attached to one side of the voice coil 11, and the adsorption surface 13 is provided on the side of the resonant body 12 away from the voice coil 11. The adsorption surface 13 is used as a medium surface with the outside world. (Such as the surface of a plastic structure, a glass panel, a wall or a ceramic tile panel, a wooden table top, a surface of a metal structure, etc.), the voice coil 11 will vibrate when it is supplied with an audio current to drive the resonant body 12 to vibrate together and resonate. The vibration of the body 12 will drive the medium surface to vibrate together, that is, resonate, to emit sound; this application improves the structure of the existing speaker 1, eliminating the need for a basin frame, and designing an adsorption surface 13 for combining with the medium surface to emit sound. The main body is transferred from the basin frame to the medium surface. In this way, the structural size of the speaker 1 can be greatly reduced, so that it can be small, lightweight, and does not take up space. It can also fit with the medium surface to ensure that beautiful vocal music can be emitted.

The traditional audio speaker 1 includes a voice coil 11, a magnet and a basket. When the voice coil 11 is supplied with an audio current, it will generate a magnetic field. This magnetic field will interact with the magnetic field generated by the magnet. In turn, the voice coil 11 will be attracted by the magnet. The magnetic force of the magnetic field drives and vibrates relative to the magnet to drive the basin frame to vibrate and produce sound.

The sound generation principle of the traditional audio speaker 1 is the same. When the voice coil 11 of the present application is supplied with an audio current, it will generate a magnetic field, and this magnetic field will also interact with the magnetic field generated by the magnet.

The audio current mentioned in this application can refer to the current in the circuit when playing music. The volume, timbre or sound quality of a song may be different at different times, that is, the intensity of the audio current is different at different times. , in this way, the magnetic field generated by the voice coil 11 will be different, and the magnetic field strength will be different at different times, that is, the voice coil 11 will be affected by the force of the magnetic field generated by the magnet at different times, and the vibration amplitude of the voice coil 11 will be different. , in this way, different sound waves will be formed. When these sound waves are transmitted to the medium surface, they will cause the medium surface to vibrate, and the vibration amplitude will be large or small, thus forming regular and beautiful music.

Different from the traditional speaker 1, the sound-emitting body of the speaker 1 of this application does not lie on the speaker 1, but on the medium surface in contact with the speaker 1; when it is not mounted on the medium surface, the sound of the speaker 1 It's very subdued. It should also be noted here that different dielectric surfaces will have different frequencies when they reach resonance due to their material characteristics, size and temperature of the dielectric surface. In general, the sound effect of hard dielectric surfaces is the best. Among them, the wooden tabletop or iron surface has the best effect. The soft medium surface can produce sound, but the sound effect will be relatively poor. Therefore, the speaker 1 of the present application is generally used on the hard medium surface.

Furthermore, the speaker 1 of the present application can select the material of the adsorption surface 13 appropriately according to the usage scenario, so as to ensure that the speaker 1 can be tightly attached to the medium surface.

For example, if the adsorption surface 13 of the present application is an adhesive surface, then the speaker 1 of the present application can be mounted on a wall, a wooden tabletop or a flat furniture surface such as a microwave oven; if the adsorption surface 13 of the present application is a magnetic surface. , then the speaker 1 of this application can be mounted on some furniture with metal shells such as refrigerators; if the adsorption surface 13 of this application is the surface of a suction cup, then the speaker 1 of this application can be adsorbed and connected to some smooth surfaces such as mirrors, mirrors, etc. Ceramic tile surface etc.

Alternatively, as shown in Figure 3, the speaker 1 also has an adhesive surface, which is provided on one side of the resonant body 12; one side of the resonant body 12 is coated with glue or adhesive particles to form an adhesive surface. . Alternatively, the speaker 1 further includes a double-sided adhesive tape 19 attached to one side of the resonant body 12 , and the side of the double-sided adhesive tape 19 away from the resonant body 12 is the adhesive surface. The thickness of the double-sided adhesive tape 19 is 1.5mm-5mm.

In some embodiments, the side of the resonant body 12 facing away from the voice coil 11 is coated with glue or adhesive particles to form an adhesive surface. That is, the resonant body 12 and the adhesive surface are an integral structure. In this way, the resonant body 12 is directly connected to the medium. The surface is adsorbed and connected, so that the vibration of the voice coil 11 can be well transmitted to the dielectric surface, causing resonance of the dielectric surface without excessive vibration energy loss.

In some embodiments, the speaker 1 further includes a double-sided adhesive tape 19 , which is attached to the side of the resonant body 12 away from the voice coil 11 , and the side of the double-sided adhesive tape 19 away from the resonant body 12 is glued. surface, the resonant body 12 and the dielectric surface can also be closely connected through the double-sided adhesive tape 19, and because the double-sided adhesive tape 19 has plasticity, the resonance can be well filled when the resonant body 12 and the dielectric surface are squeezed against each other. The gap between the body 12 and the medium surface is to prevent vibration energy from being lost from these gaps.

Specifically, the thickness of the double-sided adhesive tape 19 is 1.5mm-5mm. If the double-sided adhesive tape 19 is too thick, a large part of the vibration energy of the resonant body 12 will be absorbed by the double-sided adhesive tape 19 and thus transferred to the medium surface. The vibration energy on the resonant body 19 is very little. If the double-sided adhesive tape 19 is too thin, firstly, the processing is difficult, and secondly, the double-sided adhesive tape 19 cannot fill the gap between the resonant body 12 and the dielectric surface well. In this way, It will affect the transmission of vibration and the sound effect of the medium surface. In this application, the thickness of the double-sided adhesive tape 19 is selected to be 1.5mm-5mm to avoid the above problems; generally speaking, a double-sided adhesive tape 19 with a suitable thickness is selected according to the outer diameter of the resonant body 12, and the resonant body When the outer diameter of the resonance body 12 is greater than or equal to 30mm, you can choose a double-sided adhesive tape 19 with a thickness of 3mm-5mm. When the outer diameter of the resonant body 12 is less than 30mm, you can generally choose a double-sided adhesive tape 19 with a thickness of 1.5mm-3mm.

In this application, the double-sided adhesive tape 19 and the resonant body 12 are designed separately into two structural parts, so that the double-sided adhesive tape 19 and the resonant body 12 can be manufactured at the same time, thereby shortening the construction period and accelerating production.

In addition, the voice coil 11 of the speaker 1 of the present application can also be called an inductor coil. Generally, wires need to be wound around a ferrous medium in a ring shape. When current is passed through, a uniform and symmetrical magnetic field will be generated, which is similar to the magnetic field generated by the magnet. When interacting, the vibration direction of the voice coil 11 is determined according to the direction of the magnetic field.

It is said above that the wooden desktop or iron surface has the best resonance effect. Therefore, the adsorption surface 13 of the present application includes a magnetic surface. The magnetic surface is configured to be adsorbed and connected with the iron surface or the magnetic surface. The speaker 1 is attached to the iron surface through the magnetic surface. Installed on the iron surface or magnetic surface, for example, it can be mounted on the outer shell surface of the refrigerator. Moreover, the magnetic surface of the speaker 1, compared with the suction cup or adhesive surface, is "actively" adsorbed to the surface of the refrigerator. The speaker 1 will not fall off relative to the surface of the refrigerator when vibrating, so as to ensure that the speaker 1 can smoothly cause the surface of the refrigerator to vibrate and resonate on the surface of the refrigerator. And it can be repeatedly mounted on the surface of the refrigerator, or pulled out from the surface of the refrigerator, without affecting the effect of subsequent mounting on the surface of the refrigerator and resonating with the refrigerator.

In addition, the magnetic suction surface of the present application can be indirectly adsorbed and connected to the iron surface or the magnetic surface. That is, for some furniture, the outside is a plastic shell and the inside is an iron structure. In this way, the magnetic suction surface of the present application can also be used with these pieces of furniture. Furniture suction connections.

In some embodiments, in order to ensure the sound effect, the area of the medium surface should be greater than or equal to 5 times the area of the adsorption surface 13, and the ratio of the area of the medium surface to the area of the adsorption surface 13 is (5-10): 1 , the sound effect on the medium surface is the best.

In some embodiments, the resonant body 12 has a magnetic surface, that is, the resonant body 12 is made of magnetic material, or one side of the resonant body 12 is coated with magnetic material to form a magnetic surface; the resonant body 12 It has a magnetic surface, so that the connection between the resonant body 12 and the medium surface will be more consistent. The resonant body 12 is "actively" adsorbed on the medium surface. This is conducive to the resonant body 12 transmitting vibration to the medium surface, causing resonance of the medium surface.

Alternatively, the speaker 1 further includes a magnetic patch 14. The magnetic patch 14 is attached to the side of the resonator 12 away from the voice coil 11. The magnetic patch 14 has a magnetic surface and can be attached using welding technology, adhesive technology or high-pressure pressing. Technology, the magnetic patch 14 is pressed against one side of the resonant body 12, and the magnetic patch 14 and the resonant body 12 are integrated as much as possible to ensure that the vibration of the resonant body 12 can be well transmitted to the medium surface.

The magnetic patch 14 is mounted on the resonant body 12. The process is simple and easy to operate. The magnetic patch 14 and the resonant body 12 can be processed separately. The magnetic patch 14 and the resonant body 12 can be processed at the same time to reduce the manufacturing period. .

Specifically, the magnetic patch 14 includes a soft magnetic patch 14 and a hard magnetic patch 14. The soft magnetic patch 14 is mainly made of NdFeB soft magnetic material, strong soft magnetic material or ferrite soft magnetic material. The magnetic patch 14 is soft and gentle. When it comes into contact with the dielectric surface, it will deform to fill the gap between the resonant body 12 and the dielectric surface, so that the resonant body 12 and the dielectric surface fit closely. In this way , the vibration of the resonant body 12 can be better transmitted to the medium surface; similarly, the hard magnetic patch 14 is mainly made of ferrite magnetic material, strong magnetic material or neodymium iron boron magnetic material, but due to the hard magnetic patch 14 has a certain stiffness, will not deform when in contact with the dielectric surface, and cannot fully fill the gap between the resonant body 12 and the dielectric surface. In this way, the resonance effect of the dielectric surface is not as good as the soft magnetic patch 14.

In some embodiments, the resonant body 12 includes a resonant diaphragm, which is similar to the diaphragm of the traditional audio speaker 1. One side of the diaphragm of the traditional audio speaker 1 is connected to the voice coil 11, and the other side is connected to the basin frame. The basin frame has The vibration of the diaphragm drives the paper diaphragm on the basket to vibrate to emit sound. Therefore, one side of the resonant diaphragm of the present application is connected to the voice coil 11 and the other side is connected to the medium surface. The resonance diaphragm vibrates to drive the paper diaphragm. The medium surface resonates to produce sound; it can be said that the resonant diaphragm better transmits the vibration of the voice coil 11 to the medium surface, so that the medium surface can emit better sound; without the resonant diaphragm, the voice coil 11. Direct contact with the medium surface. In this way, the vibration of the medium surface will be affected to some extent, and the sound effect will be poor.

Furthermore, the radius of the resonant diaphragm of the present application is equal to the radius of the voice coil 11, but it can also be slightly larger or slightly smaller than the radius of the voice coil 11. In this way, the effect of the resonant diaphragm in transmitting vibration is the best.

In some embodiments, the speaker 1 further includes a first magnet 15 and an iron rod 16; the first magnet 15 is set on the outer periphery of the iron rod 16, the voice coil 11 is provided on one side of the first magnet 15, and the resonant body 12 is located on the sound side. The side of the coil 11 facing away from the first magnet 15; alternatively, the speaker 1 also includes a second magnet 17 and an iron cylinder 18; the second magnet 17 is provided inside the iron cylinder 18, and the voice coil 11 is provided on the second magnet 17 On one side, the resonant body 12 is located on the side of the voice coil 11 away from the second magnet 17 .

Either the first magnet 15 or the second magnet 17 can generate a constant magnetic field. After the voice coil 11 is supplied with an audio current, it will also generate a magnetic field. In this way, the magnetic field of the first magnet 15 or the second magnet 17 is consistent with the magnetic field of the voice coil 11 will interact, the magnetic field of the first magnet 15 or the second magnet 17 will push the voice coil 11 to move, and since the magnetic field strength of the voice coil 11 will change at any time, the magnetic field of the first magnet 15 or the second magnet 17 will Pushing the voice coil 11 to move back and forth causes the voice coil 11 to vibrate, thereby driving the resonant body 12 to vibrate, which in turn drives the medium surface to vibrate, thereby producing sound.

The speaker 1 of the present application can also use a magnetostrictive rare earth speaker, an electromagnetic drive speaker or a vibration speaker. The magnetostrictive rare earth speaker, electromagnetic drive speaker or vibration speaker all include a resonant body 12. After that, the resonant body 12 of these speakers is connected with the medium. By connecting the surface, the medium surface can also vibrate and produce sound.

As shown in Figures 1 to 12 and 15, the embodiment of the present application proposes an attached resonant speaker, which includes a housing 2, a speaker 1 and an adsorbing part 3; one side of the housing 2 is provided with a passage Hole 21; the speaker 1 includes a resonant body 12, which is configured to extend out of the housing 2 through the through hole 21, that is, the resonant body 12 vibrates and can extend out of the through hole 21 or retract into the through hole 21; The adsorption component 3 has an adsorption connection surface 31 . The adsorption component 3 is arranged on the housing 2 , and the adsorption connection surface 31 and the through hole 21 are located on the same side of the housing 2 .

The adsorption part 3 is arranged on the housing 2. The adsorption part 3 has an adsorption connection surface 31. The adsorption connection surface 31 and the through hole 21 are located on the same side of the housing 2. The adsorption connection surface 31 is used to communicate with the external medium surface (such as plastic). Structural surface, glass plate, wall or ceramic tile plate, wooden tabletop and metal structure surface) are adsorbed and connected, so as to realize the resonant speaker to be mounted on the medium surface; the resonant body 12 vibrates and will protrude outside the through hole 21 Or it can be retracted into the through hole 21 and cause the medium surface to vibrate together to achieve resonance and emit sound. The resonance speaker of this application is designed with a structure called an adsorption part 3, so that the resonance speaker can be easily connected to the medium surface by adsorption. And it can be adsorbed and connected to different types of media surfaces (such as plastic structural surfaces, glass panels, walls or ceramic tile panels, wooden desktops and metal structural surfaces). This expands the scope of application of this resonance speaker to meet the needs of users. Audio playback requirements in specific scenarios (such as bathrooms, kitchens, etc.).

In some embodiments, the adsorption part 3 includes a magnetic part 32 and a suction cup (not shown in the drawings). The magnetic part 32 and the suction cup both have adsorption connection surfaces 31. Some furniture such as refrigerators, dressing mirrors or bathroom Mirrors and refrigerators have a very flat and large iron surface. The magnetic pieces can be adsorbed and connected to the iron surface of the refrigerator, so that the resonant body 12 can cause resonance and sound on the iron surface, while the suction cups can be adsorbed and connected to the smooth mirror surface. on, so that the resonant body 12 can cause the smooth mirror surface to resonate and produce sound.

The principle of the magnetic suction piece 32 adsorbing on the iron surface of the refrigerator is: the principle of opposite properties of magnets attracting each other; the principle of the suction cup adsorbing on the smooth mirror surface is: pressing the suction cup against the smooth mirror surface to exhaust all the air between the suction cup and the smooth mirror surface. , there is no air between the suction cup and the smooth mirror, the pressure is very small, and the pressure difference with the atmospheric pressure is large. Therefore, under the action of the pressure difference, the suction cup is pressed against the smooth mirror.

This application can design the structure of the adsorption part 3 accordingly according to the material characteristics of the medium surface to be attached. For example, for some walls, the magnetic adsorption part 32 or the suction cup cannot be used, but the double-sided adhesive tape 19 can be used. The double-sided adhesive tape 19 is connected to one side of the resonant body 12, and the other side of the double-sided adhesive tape 19 can be connected to the wall. In this way, the resonant speaker of the present application can be attached to the wall, which can cause resonance on the wall and achieve speak out.

Whether the magnetic suction part 32 is used, or the suction cup or double-sided adhesive tape is used, it will not increase the manufacturing difficulty of the resonance speaker and increase the working hours. Therefore, the magnetic suction part, suction cup or double-sided adhesive tape can be appropriately selected according to the actual market demand. Double-sided adhesive tape serves as adsorbent part 3.

In some embodiments, the magnetic attraction component 32 includes an annular magnet. The annular magnet is sleeved on the outer periphery of the through hole 21 , and the side of the annular magnet facing away from the housing 2 is the adsorption connection surface 31 ; alternatively, the magnetic attraction component 32 includes several The magnets are distributed around the periphery of the through hole 21 , and the side of the magnets away from the housing 2 is the adsorption connection surface 31 .

The annular magnet is set on the outer periphery of the through hole 21, or a plurality of magnets are distributed around the outer periphery of the through hole 21. Therefore, when the resonant sound is attached to the iron sheet surface, the magnetic field between the annular magnet or the magnet and the iron sheet surface The force surrounds the periphery of the through hole 21, so that the surface of the resonant body 12 can fully contact the surface of the iron sheet without warping at any point. This ensures that the vibration of the resonant body 12 can be well transmitted to the surface of the iron sheet. , to cause the iron surface to resonate and produce sound.

Furthermore, the annular magnet is concentric with the center of the through hole 21 , or multiple magnets are evenly distributed around the outer periphery of the through hole 21 . In this way, the magnetic field force between the annular magnet or the magnet and the iron sheet surface is symmetrically distributed around the outer periphery of the through hole 21 , in this way, when the resonant body 12 resonates with the iron sheet surface, it is least affected by the iron sheet surface, and the vibration of the resonant body 12 will not be offset relative to the through hole 21; here, the ring magnet is concentric with the center of the through hole 21, or more The magnets are evenly distributed around the periphery of the through hole 21, which can improve the stability of the speaker 1, so that the speaker 1 can vibrate stably and cause resonance on the iron surface.

One side of the diaphragm of the traditional audio speaker 1 is connected to the voice coil 11, and the other side is connected to the basin frame. The basin frame has The vibration of the diaphragm drives the paper diaphragm on the basket to vibrate to emit sound. Therefore, one side of the resonant diaphragm of the present application is connected to the voice coil 11 and the other side is connected to the medium surface. The resonance diaphragm vibrates to drive the paper diaphragm. The medium surface resonates to produce sound; it can be said that the resonant diaphragm better transmits the vibration of the voice coil 11 to the medium surface, so that the medium surface can emit better sound; without the resonant diaphragm, the voice coil 11. Direct contact with the medium surface. In this way, the vibration of the medium surface will be affected to some extent, and the sound effect will be poor.

Furthermore, the radius of the resonant diaphragm of the present application is equal to the radius of the voice coil 11, but it can also be slightly larger or slightly smaller than the radius of the voice coil 11. In this way, the effect of the resonant diaphragm in transmitting vibration is the best.

In some embodiments, the speaker 1 also includes a voice coil 11, a sounding magnet 323 and a ferrous medium (not shown in the drawings); the ferrous medium includes an iron rod and an iron cylinder; generally, the sounding magnet 323 is provided on the voice coil 11 On one side of the voice coil 11 , the resonant body 12 is attached to the other side of the voice coil 11 , and the ferrous medium is located on the other side of the sound-generating magnet 323 .

The volume, timbre or sound quality of a song may be different at different times, that is, the intensity of the audio current is different at different times. , in this way, the magnetic field generated by the voice coil 11 will be different, and the magnetic field strength will be different at different times. That is, the voice coil 11 will be affected by the force of the magnetic field generated by the sounding magnet 323 at different times, and the vibration amplitude of the voice coil 11 will be different. Different, different sound waves will be formed. When these sound waves are transmitted to the medium surface, they will cause the medium surface to vibrate, and the vibration amplitude will be large or small, thus forming regular and beautiful music.

Different from the traditional speaker 1, the sound-emitting body of the speaker 1 of this application does not lie on the speaker 1, but on the medium surface in contact with the speaker 1; when the resonant sound is not mounted on the medium surface, the speaker 1's vocalization is very deep. It should also be noted here that different dielectric surfaces will have different frequencies when they reach resonance due to their material characteristics, size and temperature of the dielectric surface. In general, the sound effect of hard dielectric surfaces is the best. Among them, the wooden tabletop or iron surface has the best effect. The soft medium surface can produce sound, but the sound effect will be relatively poor. Therefore, the speaker 1 of the present application is generally used on the hard medium surface.

The second damping member 24 is used to slow down the vibration of the voice coil 11 . The vibration is transmitted to the inner wall of the through hole 21, that is, the housing 2, so as to slow down the vibration energy of the voice coil 11 and transmit it to the housing 2, thereby reducing the loss of vibration energy and allowing more vibration energy to be transmitted to the medium surface.

In addition, by reducing the vibration energy transmitted to the housing 2, the vibration of the housing 2 will be very slight, so that the housing 2 will not vibrate relative to the medium surface and fall off from the medium surface.

In one embodiment, there may be multiple display devices, for example, there may be 4 display devices (L1-L4). The combination of L1-L4 is 2×2 (i.e. two rows and two columns), with the front of the display (LED dot matrix screen) pointing in the same direction, thus forming a large rectangular screen. However, it should be understood that the combination of display devices can also be 2×3, 2×4, 2×5, 2×6, 2×7, 2×8, 3×3, 3×4, 3×5, 4× 4, etc., the size, resolution, etc. of the display screens of each display device do not need to be exactly the same, and their front faces do not need to point in the same direction.

The operation method of the display system of this embodiment is as follows. It should be understood that the following operation method is only used to better understand the structure and function of the display system of this embodiment, rather than the technical improvement of the present invention itself.

The display method includes the following steps: the control terminal scans nearby display devices to pair with each display device; configures the display mode at the control terminal or display device according to the number and combination of each display device, and configures a corresponding display device for each display device The device serial number; the control end divides the image data to be transmitted into sub-image data according to the display mode; the control end sends the corresponding sub-image data to each display device according to the corresponding device serial number; each display device caches the received sub-images data, after receiving the play command, play the sub-image data at the same time.

The workflow and steps of the above two parts are introduced in detail below (note that the display devices L1-L4 below are collectively referred to as the display devices L1-L4, and the control terminal 1 is called the mobile phone).

Part one, mobile phone process

The functions of the mobile phone are divided into the following parts: 1: connecting the device; 2: drawing a single picture; 3: sending a set of animations; 4: sending real-time video; these parts are now described.

Regarding the display mode of multiple display devices, due to consideration of description complexity, this article only considers the description of a maximum of 16 display devices. However, the method of the present invention does not limit the maximum number of display devices to 16. The system will provide multi-device templates so that users can easily choose the appropriate pattern. The template categories provided are 2×3, 2×4, 2×5, 2×6, 2×7, 2×8, 3×3, and 3×4. , 3×5, 4×4, etc. In this way, the basic template is the arrangement of user equipment. For example, 2×2 means that the user currently wants to operate four devices. The arrangement of the equipment is two rows and two columns; 3×4 is Three rows and four columns.

First: The user selects the appropriate device template based on the current number and placement of display devices through the mobile phone APP. For example, 4 display devices can correspond to 1×4, 2×2, 4×1 and other device templates;

Second: The artboard is displayed as the pixel size of the selected template. For example, if each display device currently has X×Y pixels and the user selects an N×M template, the current APP’s artboard will become (X×N)× (Y×M) image points;

Third: Click the button to add a device on the mobile APP. At this time, the APP will search for a display device whose Bluetooth device name includes a certain keyword, such as divoom-timebox. If found, it will establish a connection with the display device L1 and connect it through BLE or SPP. Connect the first display device L1, and the number 1 is displayed on the display device L1, indicating that this is the first position. The sequence numbers are arranged in an N×M template, increasing from left to right and top to bottom. The first display device has a serial number of 1, and the last display device has a serial number of N×M.

Fourth: Display device L1 then searches for a display device whose Bluetooth device name includes a certain keyword, such as divoom-timebox. If found, it will establish a connection with the new display device L2, and display device L1 assigns a unique serial number to display device L2. 2. Send the serial number to the display device L2 through BLE or SPP, and the screen of the display device L2 displays 2;

Fifth: Display device L3 then searches for a display device whose Bluetooth device name includes a certain keyword, such as divoom-timebox. If found, it will establish a connection with the new display device L3, and display device L2 assigns a unique serial number to display device L3. 3. Send the serial number to the display device L3 through BLE or SPP, and the screen of the display device L3 displays 3;

Sixth: Repeat step five and directly receive the stop search command from the mobile APP.

The connection method between mobile phones and monitors (also called display devices) can be referred to. A single-chain serial connection is established between mobile phones and all display devices, which has the following advantages: According to the existing Bluetooth standard, one Bluetooth device can connect 7 devices at the same time. Bluetooth devices can be connected in series to expand the number of connected display devices.

Among them, the display mode can be set on the mobile phone in advance, or you can scan and add nearby Bluetooth devices first, and then Or the device configures the display mode according to the number and combination of each display device, and configures the corresponding device serial number for the display device.

In addition, the mobile phone can also search for all devices whose Bluetooth device names include a certain keyword, obtain the MAC address of the Bluetooth module (i.e., the first wireless communication module) of each device L1-L4, and assign a unique device to each display device. sequence.

As shown in Figures 1-3 and 17, this application provides a teaching board with an attached speaker, including a board body 10 and an attached speaker. The attached audio system includes a housing 2 and a speaker 1 . One side of the housing 2 is provided with a through hole. The housing 2 is provided with an inner cavity inside. The inner cavity is connected with the through hole. The speaker 1 includes a resonant body 12 which is disposed in the inner cavity of the housing 2 and extends at least partially from the through hole to the outside of the housing 2 . The resonant body 12 vibrates based on the audio current. The resonant body 12 is provided with a connecting surface. The connecting surface is attached to the surface of the board body 10 .

In the above-mentioned teaching board with attached speakers, the speaker 1 is attached to the board 10 through the connecting surface, and can transmit the sound to the board 10 through the resonant body 12 and the shell 2, driving the surface of the board 10 to vibrate, thereby further To amplify the sound emitted by the speaker 1, that is, by utilizing the working principle of the attached speaker itself to vibrate and sound and the large area of the panel 10, the main body of the amplification is transferred to the panel 10, so that the panel 10 serves as a medium surface for sound transmission. The volume of the sound transmitted through the speaker 1 is effectively increased, which not only has a good amplification effect, but also effectively reduces the requirements for the amplification power of the speaker 1.

It should be noted that, unlike the traditional speaker 1 , the sound-emitting body of the speaker 1 in this application does not lie on the speaker 1 , but on the plate 10 that is detached from the speaker 1 . When not mounted on the board 10, the sound emitted by the speaker 1 itself is very low; when mounted on the board 10, the speaker 1 transmits the vibration of the sound to the board 10 through the resonant body 12, and The sound is amplified by the panel body 10 to achieve the effect of sound amplification.

It should also be noted that due to differences in material properties, dimensions, and surface temperatures of the plate 10 , the frequencies at which different plates 10 and the resonant body 12 reach resonance will be different. In general, the plate 10 with a higher hardness will The sound amplification effect will be better than the sound amplification effect of the board 10 with smaller hardness.

In this application, the inner diameter of the through hole is to adapt to the outer diameter of the resonant body 12 to ensure that the resonant body 12 will not be hindered when extending in and out. At the same time, it is also necessary to ensure that the distance between the resonant body 12 and the inner wall of the through hole is maintained. If there is a gap between the resonant body 12 and the inner wall of the through hole, the sound waves will be transmitted directly from these gaps, and the resulting sound effect will be very poor. The outer diameter of the resonant body 12 of the present application is 15mm-50mm, and the inner diameter of the through hole is 15mm-50mm, preferably 30mm-50mm.

It can be understood that the board body 10 in this application can be a blackboard, a whiteboard, an electronic teaching device, etc. that are installed in the teacher and can be used by the teacher to write on the blackboard.

In one embodiment, as shown in Figure 1, the speaker 1 also includes a sound collecting device (not shown) and a signal transmission device. The signal transmission device is communicated with the radio device. The signal transmission device is communicatively connected with the resonant body 12 . Therefore, the sound collection device transmits the collected sound to the signal transmission device in the form of electrical signals. The signal transmission device transmits the electrical signal to the resonant body 12 in the form of audio current. The resonant body 12 vibrates under the action of the audio current and drives the surface of the plate 10 to vibrate together, thereby realizing the reception, transmission and vibration of the audio signal. , and the steps of amplification, that is, to achieve the technical effect of amplification.

Further, the communication method between the radio device and the signal transmission device may be Bluetooth transmission, FM transmission, or wireless transmission. At least one of the network transmission. Among them, wireless network transmission can be 3G, 4G, 5G, etc. The above-mentioned communication methods can separate the radio device from the speaker 1 body, that is, the teacher can carry a portable radio device, such as a portable microphone, etc., to realize the separation of radio and amplification, so as to avoid restricting the teacher's position during the lecture. It is conducive to improving the classroom experience and teaching quality of teachers and students.

In one embodiment, as shown in FIG. 1 , the panel 10 includes a display screen (not shown). The display screen is nested on the board body 10 . The display screen can be an LCD liquid crystal display screen. In actual use, in order to facilitate all students in the teacher to view the screen, the LCD screen can be set in the middle of the board 10, and a layer of touch glass can be covered outside the board 10 and the LCD screen. The touch glass can be configured to recognize the teacher's writing track on the touch glass and retain the writing on the blackboard.

In one embodiment, the speaker 1 further includes a voice coil 11 . The voice coil 11 is configured to be supplied with audio current to generate vibration. The resonant body 12 is mounted on the side of the voice coil 11 facing the plate 10 and resonates with the voice coil 11 . The connection surface is provided on the side of the resonant body 12 away from the voice coil 11 (that is, the side of the resonant body 12 facing the plate body 10). Therefore, the connection surface is used to connect with the plate body 10 . When the voice coil 11 is supplied with audio frequency current, it will vibrate and drive the resonant body 12 to vibrate together. When the resonant body 12 vibrates, it will drive the plate body 10 to vibrate together, that is, to resonate, so as to emit sound. Since the volume of the sound emitted through the speaker 1 and the panel 10 is greater than the volume of the sound received by the sound receiving device, this process can ultimately achieve a sound amplification effect.

In addition, the speaker 1 used in this application is essentially a stick-on speaker. Compared with the existing loudspeaker device, the structural size of the speaker 1 is greatly reduced, making it small and lightweight, and does not take up space. Moreover, it can cooperate with the board body 10 to achieve the effect of sound amplification.

It should be noted that, similar to the sound generation principle of traditional speakers, the voice coil 11 in this application will generate a magnetic field when it is supplied with an audio current, and this magnetic field will also interact with the magnetic field generated by the magnet.

As shown in Figures 1, 2, and 16, a piezoelectric ceramic resonant speaker 100 includes a housing 2, a speaker 1, and a magnetic resonance film. One side of the housing 2 is provided with a through hole (not labeled in the figure). The speaker 1 includes a resonant body 12 and a piezoelectric ceramic sheet 220 . The resonant body 12 is configured to vibrate according to the audio current and extend out of the through hole or retract into the through hole. The resonant body 12 is provided with a connecting surface. The connection surface is used to attach to the media surface. The piezoelectric ceramic piece 220 is connected to the resonant body 12 . The magnetic resonance film is connected to the side of the speaker 1 facing the medium surface.

It can be seen from this that the above-mentioned piezoelectric ceramic resonant speaker 100 can vibrate through audio current, and the resonant body 12 can vibrate according to the audio current. The resonant body 12 drives the dielectric surface to vibrate together, that is, to resonate, to emit sound; the connection surface can improve the resonance of the resonant body. 12 and the connection stability of the media surface to ensure the stability of sound transmission. In addition, installing piezoelectric ceramics on the speaker 1 can further take into account high and low frequency sounds, widen the sound reproduction frequency band, improve the sound quality of the sound, and bring better listening enjoyment to the user.

It should be noted that the above-mentioned medium surface should be understood as the surface of a plastic structure, a glass surface, a wall surface, a tile surface, a wood surface, or a metal structure surface, etc.

Furthermore, the dielectric surface may be flat to improve the connection stability between the dielectric surface and the resonant body 12 . For example, during use, the connecting surface sticker can be connected to the surface of flat furniture. For example, the Yao Dan ceramic resonant speaker in this application can be mounted on the surface of furniture such as refrigerators and microwave ovens. Of course, the dielectric surface can also be a curved surface. In this case, the resonance body 12 and the dielectric surface The fitting side should be able to fit into the media surface.

It should also be noted that the shape of the piezoelectric ceramic sheet 220 may be circular, square, etc., which is not limited here.

It should also be noted that due to differences in material properties, dimensions, and plate surface temperatures, the frequencies at which different dielectric surfaces reach resonance with the resonant body 12 will be different. In general, the sound amplification of a dielectric surface with greater hardness will be different. The effect will be better than the amplification effect of the medium surface with less hardness.

In this application, the inner diameter of the through hole is to adapt to the outer diameter of the resonant body 12 to ensure that the resonant body 12 will not be hindered when extending in and out. At the same time, it is also necessary to ensure that the distance between the resonant body 12 and the inner wall of the through hole is maintained. If there is a gap between the resonant body 12 and the inner wall of the through hole, the sound waves will be transmitted directly from these gaps, and the resulting sound effect will be very poor. The outer diameter of the resonant body 12 of the present application is 15mm-50mm, and the inner diameter of the through hole is 15mm-50mm, preferably 30mm-50mm.

Understandably, the magnetic resonance film vibrates to drive the medium surface to resonate, thereby emitting sound; it can be said that the magnetic resonance film better transmits the vibration of the voice coil 11 to the medium surface, so that the medium surface can emit more pleasant sounds. sound; if there is no magnetic resonance film, the voice coil 11 directly contacts the medium surface, so the vibration of the medium surface will be affected to some extent, and the sound effect will be poor.

Furthermore, the radius of the resonant film of the present application is equal to the radius of the voice coil 11, but it can also be slightly larger or slightly smaller than the radius of the voice coil 11. In this way, the resonant film has the best effect of transmitting vibrations.

As shown in FIG. 1 , in one embodiment, the area S1 of the side of the piezoelectric ceramic sheet 220 facing the dielectric surface is larger than the area S1 of the side of the housing 2 facing the dielectric surface. The larger the area between the piezoelectric ceramic piece 220 and the dielectric surface, the greater the volume of the sound it emits through resonance, which is helpful for prompting, warning, and expelling effects in some special occasions. For example, the piezoelectric ceramic resonant speaker 100 in this application can be attached to a larger wall in a public place. The smaller vibration of the resonant body 12 can gradually amplify the sound through the piezoelectric ceramic sheet 220 and the dielectric surface. It is conducive to issuing warning sounds in emergencies, assisting in conveying information, dispersing crowds, etc.

In addition, the piezoelectric ceramic resonant speaker 100 can also be used in airport terminals and other places where birds need to be avoided: the piezoelectric ceramic resonant speaker 100 is attached to the outer wall of a tower, and the outer wall of the tower serves as The medium surface can amplify the sound and is used to expel birds, avoid aircraft and bird flocks from meeting, and prevent accidents.

Furthermore, because magnetic materials with low coercivity (also known as permeable materials) have high saturation magnetic flux density, high magnetic permeability, long and narrow hysteresis loops, small area, small hysteresis loss, and residual magnetism And characteristics such as small coercive force. Therefore, both soft magnetic materials and hard magnetic materials can be used in the resonant film of the piezoelectric ceramic resonant speaker 100, which is conducive to further improving the quality of the sound and bringing better listening enjoyment to the user.

Furthermore, in this embodiment, the edge of the magnetic resonance film is supported on the housing 2 . The magnetic resonance film is conical in shape.

In one embodiment, the number of piezoelectric ceramic sheets 220 is at least two. At least two piezoelectric ceramic sheets 220 are connected in parallel through internal electrodes. At least two piezoelectric ceramic sheets 220 are connected with leads. The leads are led out through the housing 2. The multilayer piezoelectric ceramic piece 220 is led out through the PCB or a special connection terminal. The lead is connected to the multilayer piezoelectric ceramic piece 220 and led out through the housing 2. The audio signal is introduced through the PCB or the rotating connection terminal fixedly installed in the housing 2. Make the transition. Multilayer piezoelectric ceramics The leads on the sheet 220 are connected by welding or bonding with soft wires or soft foils, and the other end is connected to a dedicated connection terminal, so that the audio signal can be accessed through the audio jack fixed on the PCB or the dedicated terminal.

The storage module is communicatively connected to the central processing module and is used to store specified information. The display module is communicatively connected to the central processing module and is used to display specified information.

It can be seen that the above-mentioned multifunctional resonant speaker 100 can receive designated information through the receiving module and transmit the designated information to the central processing module. After being processed by the central processing module, the designated information can be converted into audio and played out from the speaker 1. It can also be displayed in the form of patterns or text through the display module, or the specified information can be saved in the storage module, which is beneficial to broadening the scope of application of the resonance sound to meet people's diverse needs.

It should be noted that the communication information processed by the central processor can be information transmitted after being processed by the receiving module, or information retrieved from the storage module.

The "specified information" received by the receiving module is information (such as sound, etc.) that can be received and processed by the receiving module. You can set the opening prompt tone in the receiving module. When the receiving module receives the opening prompt tone, the receiving module starts working to receive the next information. For example: set the opening prompt sound to "Hello, resonance speaker". When the user says "Hello, resonance speaker" to the receiving module, the receiving module starts to work and receives other words that the user then speaks to the receiving module. information.

The "specified information" stored in the storage module can be information stored in the storage module in advance, or it can also be information transmitted from the central processing module.

The second shock absorbing member 24 is provided between the resonant body 12 and the inner wall of the through hole 21 .

It should be noted that the first damping member 23 is used to attenuate the transmission of vibration to the inner wall of the housing 2, and the second damping member 24 is used to attenuate the transmission of vibration to the inner wall of the through hole 21, that is, between the housings 2, so as to Ensure that all vibrations can be transmitted to the medium surface to ensure the sound effect.

In addition, the first damping member 23 and/or the second damping member 24 can reduce the transmission of vibration energy to the housing 2, and the vibration of the housing 2 will be very slight, so that the housing 2 will not vibrate relative to the medium surface, and will not vibrate from the medium surface. Falling off the face.

At the same time, it is also necessary to ensure that the distance between the resonant body 12 and the inner wall of the through hole 21 is good. There will be no gap between them. If there is a gap between the resonant body 12 and the inner wall of the through hole 21, the sound waves will be transmitted directly from these gaps. In this way, the resulting sound effect will be very poor. The outer diameter of the resonant body 12 of the present application is 15mm-50mm, and the inner diameter of the through hole 21 is 15mm-50mm, preferably 30mm-50mm.
