Therefore, there is a need to provide an improved vibration-damping structure.

Detailed ways

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

For electronic devices such as mobile phones, considering that the battery will expand as the use of the electronic device increases, a certain rear cavity space is usually reserved between the battery back cover and the battery in the electronic device. In order to realize the stereo effect, the earpiece in the electronic device usually adopts an open rear cavity structure, so that the earpiece communicates with the rear cavity space at the battery back cover. However, this design of the earpiece will cause the airflow generated when the sound is played through the earpiece to move in the rear cavity space, and then cause the battery back cover in the electronic device to vibrate obviously, affecting the user's feel and experience.

Regarding the shell vibration phenomenon caused by the sound of the electronic device, the inventor noticed that the amount of vibration perceived by the user's hand is not only related to the vibration amplitude of the battery back cover itself, but also related to the human body's perceived frequency. Specifically, under the condition of the same vibration amplitude, the user's hand perception is stronger in the low frequency range; the user's hand perception will drop sharply starting from the middle frequency range.

In this regard, in order to reduce the user's vibration perception of the casing, an embodiment of the present application provides an electronic device. As shown in FIG. 1 , the electronic device includes a casing 1 , a functional module 2 , an earpiece 3 and a vibration-damping layer 4 .

Wherein, the housing 1 includes a shell plate 11 . The functional module 2 is located inside the casing 1 , and there is a gap between the functional module 2 and the shell plate 11 . The earpiece 3 is arranged on the housing 1, and the earpiece 3 communicates with the gap between the functional module 2 and the shell 11 and the external environment. The vibration damping layer 4 is attached to the inner side of the shell plate 11 and is at least partially located between the functional module 2 and the shell plate 11 . The vibration-damping layer 4 is configured such that the frequency of the outgoing sound wave passing through the vibration-damping layer 4 is greater than the frequency of the incident sound wave incident through the earpiece 3 .

In the electronic device provided by the present invention, the vibration-damping layer 4 attached to the inner side of the shell plate 11 can change the frequency of the sound wave incident through the earpiece 3, and then can change the vibration frequency of the housing 1 caused by the airflow movement caused by the propagation of the sound wave; and the vibration-damping layer 4 is specifically used to increase the frequency of the sound wave, so that the vibration frequency of the housing 1 can be moved closer to the middle and high frequency bands, so as to reduce the vibration perception of the user's hand.

In addition, in the electronic device provided by the present invention, changing the frequency of the sound wave through the vibration-damping layer 4 can also avoid the resonance between the housing 1 and the sound wave, reduce the vibration of the housing of the electronic device caused by the sound, and further reduce the vibration perception of the user's hand.

In some embodiments, the vibration-damping layer 4 may use acoustically nonlinear materials to realize the function of changing the frequency of sound waves.

In some embodiments, the acoustic nonlinear material may have the function of doubling or tripling the frequency, that is, the frequency of the outgoing sound wave passing through the acoustic nonlinear material is twice to three times the frequency of the incident sound wave.

In some embodiments, the acoustically nonlinear material can be prepared in the form of a coating. The coating can be applied directly to the inner side of the shell plate 11 . Alternatively, the coating can be coated on an additional carrier layer, and the laminated structure of the coating and the carrier layer can be used as the damping layer 4, wherein the carrier layer can be attached to the inner side of the shell plate 11, and the coating can be coated on the side of the carrier layer facing away from the shell plate 11.

In some embodiments, the material of the carrier layer can be the same as that of the shell plate 11 , for example, it can be any one of metal material, ceramic material or resin material.

In some embodiments, the acoustic nonlinear material can be prepared in the form of a liquid, and the vibration-damping layer 4 can be arranged as a cylindrical structure containing the acoustic nonlinear material. The cylindrical structure can be attached to the inner side of the shell plate 11 .

In some embodiments, the acoustically nonlinear material may be a contrast medium. For the contrast agent medium, the greater the amplitude of the incident sound wave, the higher the efficiency of frequency shift conversion and the more obvious the effect. In this case, the vibration-damping layer 4 can be a contrast medium coating; or, the vibration-damping layer 4 can include a carrier layer and a contrast medium coating; or, the vibration-damping layer 4 can be a cylindrical structure containing a contrast medium. In other embodiments, the acoustic nonlinear material can also use fluorinated liquid FC-43 or similar inert liquid with low sound velocity.

In some embodiments, the vibration-damping layer 4 can be pasted on the inner side of the shell plate 11 by double-sided tape or other viscous substances.

The electronic equipment provided by the utility model uses acoustic nonlinear materials to change the frequency of sound waves to reduce the user's perception of the vibration of the housing of the electronic equipment. Compared with using foam to block the movement of the airflow to reduce the vibration of the battery back cover, the electronic equipment provided by the application uses the inherent characteristics of the material to achieve the vibration reduction effect, without artificial consideration to design a suitable foam thickness, which is simpler and more practical.

In some embodiments, the electronic device may be, for example, a mobile phone, a tablet computer, a laptop computer, a desktop computer, a wearable device, a mobile phone, a landline phone, or a hearing aid.

As shown in FIG. 1 , in an electronic device with a display function such as a mobile phone, the electronic device may further include a display panel 6 , and the display panel 6 is opposite to the shell plate 11 . The case plate 11 may be a back case of an electronic device, and the case 1 may further include a middle frame 12 . The shell plate 11 , the middle frame 12 and the display panel 6 can surround an accommodation cavity, and the functional module 2 and the vibration-damping layer 4 are located in the accommodation cavity. The handset 3 can be set on the middle frame 12 .

In some embodiments, the functional module 2 can be a battery module, which can include battery cells 21 and additional components 22 . The additional assembly 22 may include a battery management chip, a PCBA (Printed Circuit Board Assembl, printed circuit board), an FPC (Flexible Printed Circuit, flexible circuit board), and a battery protection chip. The additional component 22 can be used to control and manage the battery cell 21 to realize various functions of the battery module.

In some embodiments, battery cells 21 may be located near the bottom of the electronic device, while add-on components 22 may be located near the top of the electronic device.

In some embodiments, earpiece 3 may be located on top of the electronic device, next to add-on component 22 . Moreover, as shown in FIG. 1 , in the direction from the housing plate 11 of the electronic device to the display panel 6, the earpiece 3 can be closer to the display panel 6 relative to the vibration-damping layer 4, so that the earpiece 3 can be aligned with the gap between the vibration-damping layer 4 and the functional module 2, so that the sound wave incident through the earpiece 3 does not directly enter between the vibration-damping layer 4 and the housing plate 11, but causes the housing plate 11 to vibrate after passing through the vibration-damping layer 4.

In some embodiments, the earpiece 3 may include a sound transmission channel and electronic components such as a voice coil and a vibrating diaphragm.

Wherein, the sound transmission channel can be arranged as a hole structure, and the sound transmission channel can pass through the side wall of the middle frame 12, so as to communicate with the internal environment of the electronic device and the external environment.

The electronic components in the earpiece 3 can be arranged inside the middle frame 12 . A first cavity can be formed between the vibrating diaphragm and the middle frame 12 , and the first cavity communicates with the sound transmission channel; and a second cavity can be formed on the side of the vibrating diaphragm facing away from the middle frame 12 . When playing sound through the earpiece 3, the voice coil can be energized to make the vibrating diaphragm vibrate. The vibration of the vibrating diaphragm can realize the compression and release of the air in the first cavity and the second cavity, thereby generating airflow movement to transmit sound waves.

In some embodiments, the electronic components in the earpiece 3 can be electrically connected to the PCBA or FPC in the functional module 2 to control sound playback through the functional module 2 . In other words, in some embodiments, the functional module 2 may also be a component for realizing audio playback.

In some embodiments, the shell plate 11 and the middle frame 12 may be integrally formed. Alternatively, the shell plate 11 and the middle frame 12 can also be molded independently, and then assembled together to form the shell 1 .

Considering that the area of the battery cell 21 is much larger than the area of the additional component 22, the space corresponding to the area of the battery cell 21 for airflow movement is relatively large, which in turn causes the housing near the battery cell 21 to vibrate more violently. In some embodiments, the orthographic projection of the vibration-damping layer 4 on the shell plate 11 can cover the orthographic projection of the battery cell 21 on the shell plate 11. By arranging the vibration-damping layer 4 near the battery cell 21 , the vibration of the housing perceived by the user can be effectively reduced.

In some embodiments, the orthographic projection of the damping layer 4 on the shell plate 11 may cover the orthographic projection of the functional module 2 on the shell plate 11 . That is to say, the orthographic projection of the damping layer 4 on the shell plate 11 can cover the orthographic projection of the battery cell 21 on the shell plate 11 , and cover the orthographic projection of the additional component 22 on the shell plate 11 . By arranging the vibration-damping layer 4 near the battery cell 21 and the additional component 22 , the coverage area of the vibration-damping layer 4 is enlarged, and the housing vibration perceived by the user can be reduced more effectively.

As shown in FIG. 2 , the electronic device may further include a camera module 5 . The camera module 5 can be arranged close to the top of the electronic device, and close to the earpiece 3 also arranged on the top of the electronic device. The airflow generated in the earpiece 3 mainly flows to the rear cavity formed by the shell plate 11 through the camera module 5 , therefore, the vibration-damping layer 4 can be arranged around the camera module 5 inside the shell plate 11 .

In some embodiments, as shown in FIG. 2 , the damping layer 4 may include a first region 41 and a second region 42 . Wherein, the first area 41 can be arranged side by side with the camera module 5 along the first direction, the second area 42 can be arranged side by side with the camera module 5 along the second direction, and the first direction is perpendicular to the second direction.

In some embodiments, the first direction may be the width direction of the electronic device, and the second direction may be the length direction of the electronic device. Also, the first area 41 may correspond to the installation area of the additional component 22 , and the second area 42 may correspond to the installation area of the battery cell 21 . The area of the second region 42 may be greater than that of the first region 41 .

In some embodiments, the first area 41 and the second area 42 can be integrally formed and configured to match the shape of the shell 11 and avoid the shape of the camera module 5 , so that the first area 41 and the second area 42 can be connected to each other. Or, as shown in FIG. 2 , there may be a certain gap between the first region 41 and the second region 42 , so that the first region 41 and the second region 42 can be attached to the inner side of the shell plate 11 independently, so as to reduce processing difficulty.

In some embodiments, the area of the vibration-damping layer 4 is not less than 60% of the area of the shell plate 11, so as to ensure the vibration-damping effect of the electronic equipment.

In some embodiments, the thickness of the damping layer 4 can be in the range of 0.3mm-1mm, so as to avoid the unstable fixing of the damping layer 4 caused by the thickness of the damping layer 4 being too small, or the increase of the thickness of the electronic device due to the thickness of the damping layer 4 being too large.

The embodiment of the present application also provides a casing, which includes a casing plate 11 and a vibration-damping layer 4, the vibration-damping layer 4 is attached to the inner side of the casing plate 11, and the vibration-damping layer 4 is configured such that the frequency of the outgoing sound wave after passing through the vibration-damping layer 4 is greater than the frequency of the incident sound wave.

In some embodiments, the vibrating layer 4 can be made of acoustically nonlinear materials. The acoustic nonlinear material can be prepared in the form of a coating; or the coating can be coated on an additional carrier layer, and the laminated structure of the coating and the carrier layer can be used as a vibration damping layer 4, wherein the carrier layer can be attached to the inner side of the shell plate 11, and the coating can be coated on the side of the carrier layer away from the shell plate 11; or the vibrating layer 4 can be set as a cylindrical structure containing the acoustic nonlinear material.

In other words, the vibration-damping layer 4 can be a contrast medium coating; or the vibration-damping layer 4 can include a carrier layer and a contrast medium coating; or the vibration-damping layer 4 can be a cylindrical structure containing a contrast medium.

In some embodiments, the vibration-damping layer 4 can be pasted on the inner side of the shell plate 11 by double-sided tape or other viscous substances.

In some embodiments, the area of the damping layer 4 may not be less than 60% of the area of the shell plate 11, and the thickness of the damping layer 4 may be 0.3mm-1mm.

In the embodiments of the present invention, the terms "first" and "second" are used for description purposes only, and cannot be understood as indicating or implying relative importance. The term "plurality" means two or more, unless otherwise clearly defined.
