Description

Method for manufacturing a solidified and elastically softened speaker vibrator

The present invention relates to a solidified and elastically softened speaker vibrator and a manufacturing method thereof.

The manufacturing method of the known speaker vibration plate includes the following steps: soaking the substrate in a curing polymer; drying the substrate so that the curing polymer dries to form a curing structure, and the curing structure covers the outer surface of the substrate; embossing the speaker vibration plate on the substrate; and separating the speaker vibration plate from the substrate. The speaker vibration plate includes a body and a curing structure, and the curing structure covers the outer surface of the body.

Because the base material is usually cloth with a soft texture, the speaker diaphragm made from it is also soft. The solidified structure can increase the hardness of the entire speaker diaphragm, so that the speaker diaphragm can be vibrated by the operation of the voice coil.

However, the solidified structure is susceptible to vibration, fatigue stress, heat and other factors, resulting in problems such as hardening and aging. The higher the degree of hardening and aging of the solidified structure, the harder the hardness of the speaker diaphragm, resulting in the worse fatigue resistance and elastic expansion and contraction recovery of the speaker diaphragm. Therefore, the longer the speaker diaphragm is used, the less elastic it is, and the easier it is to fatigue, even crack, deform and fall off, affecting the output sound quality.

Furthermore, the materials of the base material and the cured polymer are completely different, resulting in different vibration frequencies of the main body and the cured structure, so that the speaker vibration plate is prone to resonant noise, which in turn leads to many problems such as high noise, difficulty in presenting low-frequency channels, poor load rebound ability, and poor output sound quality.

The main purpose of the present invention is to provide a solidified and elastically softened speaker vibration plate and a manufacturing method thereof, which can adjust the hardness and elastic coefficient of the entire block or a local block of the speaker vibration plate.

In order to achieve the above-mentioned purpose, the present invention provides a method for manufacturing a solidified and elastically softened speaker vibration plate, comprising the following steps: (a) soaking a substrate in a solidifying polymer so that the solidifying polymer is attached to all areas of an outer surface of the substrate, and the substrate has at least one pre-formed portion; (b) drying the substrate so that the solidifying polymer is dried to form a solidified structure, and the solidified structure covers all areas of the outer surface of the substrate; (c) applying heat and pressure to at least one pre-formed portion to form a speaker vibration plate; and (d) separating the speaker vibration plate from the substrate; Among them, between step (b) and step (c), or between step (c) and step (d), or after step (d), the following steps are further included: (e) using screen printing, spraying, manual coating, attachment, immersion or mask coating and other technical means to attach an elastic soft polymer to the entire area or a partial area of an outer surface of the cured structure; and (f) drying the substrate so that the elastic soft polymer dries to form an elastic soft structure, and the elastic soft structure covers the entire area or a partial area of the outer surface of the cured structure.

In some embodiments, step (e) and step (f) are performed only once or multiple times to form a single layer or multiple layers of elastic softened structure covering the entire area or partial area of the outer surface of the cured structure.

In order to achieve the above-mentioned purpose, the present invention provides a method for manufacturing a solidified and elastically softened speaker vibration plate, comprising the following steps: (a) mixing a solidified polymer and an elastically softened polymer to prepare a composite polymer, the composite polymer being attached to all areas of an outer surface of a substrate, the substrate having at least one preformed portion; (b) drying the substrate so that the composite polymer is dried to form a composite structure, the composite structure covering all areas of the outer surface of the substrate; (c) applying heat and pressure to at least one preformed portion to form a speaker vibration plate; and (d) separating the speaker vibration plate from the substrate.

In some embodiments, step (a) and step (b) are performed only once or are repeated multiple times to form a single layer or multiple layers of composite structure covering the entire area of the outer surface of the substrate.

In order to achieve the above-mentioned purpose, the present invention provides a solidified and elastically softened speaker vibration plate, including a body, a solidified structure and an elastically softened structure. The solidified structure is dried from a solidified polymer and covers the entire area of an outer surface of the body. The elastically softened structure is dried from an elastically softened polymer and covers the entire area or a partial area of an outer surface of the solidified structure.

In some embodiments, a single layer or multiple layers of elastic softening structure covers the entire area or a partial area of the outer surface of the solidified structure.

In order to achieve the above-mentioned purpose, the present invention provides a solidified and elastically softened speaker vibration plate, including a body and a composite structure.

Figures 13 and 14 are schematic diagrams of two aspects of the second embodiment of the speaker vibration plate of the present invention.

Figures 1 to 4 are respectively a flow chart of the first embodiment of the method of the present invention and a schematic diagram of steps S100 to S600. As shown in Figures 1 to 4, the present invention provides a method for manufacturing a solidified and elastically softened speaker vibration plate, comprising the following steps:

Step S100, as shown in FIG. 1 and FIG. 2, a substrate 20 is immersed in a solidifying polymer 10, and the solidifying polymer 10 is attached to all areas of an outer surface of the substrate 20, and the substrate 20 has a plurality of preformed parts 21.

Step S200, as shown in FIG. 1 and FIG. 2, the substrate 20 is dried so that the cured polymer 10 is dried to form a cured structure 32 (see FIG. 5 to FIG. 10), and the cured structure 32 covers the entire area of the outer surface of the substrate 20.

Step S300, as shown in FIG. 1 and FIG. 3A to FIG. 3F, a flexible softening polymer 11 is attached to the entire area or a partial area of the outer surface of the cured structure 32 by means of screen printing (see FIG. 3A), spraying (see FIG. 3B), manual coating (see FIG. 3C), attachment (see FIG. 3D), immersion (see FIG. 3E) or mask coating (see FIG. 3F).

Step S400, as shown in FIG. 1 and FIG. 4, the substrate 20 is dried so that the elastic soft polymer 11 is dried to form an elastic soft structure 33 (see FIG. 5 to FIG. 10), and the elastic soft structure 33 covers the entire area or a partial area of the outer surface of the cured structure 32.

Step S300 and step S400 are performed only once or multiple times to form a single layer or multiple layers of elastic softening structure 33 covering the entire area or partial area of the outer surface of the solidified structure 32.

Step S500, as shown in FIG. 1 and FIG. 4, heat and pressurize the preformed parts 21 to form a plurality of speaker vibration plates 30.

Step S600, as shown in FIG. 1 and FIG. 4, separate the speaker vibration plates 30 from the substrate 20.

It is worth mentioning that, as shown in FIG. 1 , step S300 and step S400 can also be performed between step S500 and step S600, or after step S600. Therefore, whether step S300 and step S400 are performed between step S200 and step S500, between step S500 and step S600, or after step S600, the structure of the manufactured speaker vibration plate 30 is the same.

Figures 5 to 10 are schematic diagrams of six states of the first embodiment of the speaker vibration plate 30 of the present invention. As shown in Figures 5 to 10, the present invention provides a cured and elastically softened speaker vibration plate 30A~30F, including a body 31, a cured structure 32 and an elastically softened structure 33. The cured structure 32 is dried from a cured polymer 10 and covers the entire area of an outer surface of the body 31. The single-layer or multiple-layer elastically softened structure 33 is dried from an elastically softened polymer 11 and covers the entire area or a partial area of an outer surface of the cured structure 32.

As shown in Figures 5 to 10, the common point of the six aspects of the first embodiment is that the solidified structure 32 is formed by drying the solidified polymer 10 and covers the entire area of the outer surface of the body 31. In this way, the solidified structure 32 can exert the solidification characteristics of the solidified polymer to solidify the entire body 31 and improve the hardness of the entire body 31, so that the speaker vibration plate 30A~30F can be vibrated by the operation of the voice coil.

The following will further illustrate the differences in methods, structures, and effects of the six aspects of the first embodiment with the help of diagrams.

Example 1:

In terms of the method, in step S300, the elastic soft polymer 11 is attached to the outer surface of the solidified structure 32 on the upper surface of an outer annular block of the preformed part 21; in step S400, the elastic soft structure 33 covers the outer surface of the solidified structure 32 on the upper surface of the outer annular block of the preformed part 21; step S300 and step S400 are performed only once to form a single layer of elastic soft structure 33 covering the outer surface of the solidified structure 32 on the upper surface of the outer annular block of the preformed part 21.

In terms of structure, as shown in FIG5 , a single-layer elastic softening structure 33 covers the outer surface of the solidified structure 32 on the upper surface of the outer annular block of the body 31.

In terms of efficacy, the elastic softening structure 33 can exert the elastic softening characteristics of the elastic softening polymer to soften the outer annular block of the body 31, so that the hardness of the outer annular block of the body 31 is less than the hardness of other blocks of the body 31, and at the same time improve the elastic coefficient of the outer annular block of the body 31, so that the elastic coefficient of the outer annular block of the body 31 is greater than the elastic coefficient of other blocks of the body 31. Thereby, the outer annular block of the speaker vibration plate 30A has excellent fatigue resistance and elastic expansion and contraction recovery force. The excellent fatigue resistance can make the outer ring block of the speaker vibration plate 30A less likely to break, deform and fall off. The excellent elastic recovery force can make the outer ring block of the speaker vibration plate 30A have the effects of reducing resonance noise, reducing noise, making the low-frequency channel easier to appear, and improving the load rebound ability, thereby improving the output sound quality of the speaker.

Example 2:

In terms of the method, step S300 includes the following steps: attaching the elastic soft polymer 11 to the outer surface of the solidified structure 32 on the upper surface of the outer annular block of the preformed part 21; and attaching the elastic soft polymer 11 to the outer surface of the solidified structure 32 on the upper surface of all blocks of the preformed part 21; wherein the elastic soft polymer 11 used in the two coatings of step S300 is the same material, so the thickness of the outer annular block of the elastic soft polymer 11 is greater than the elastic soft polymer 11; Step S400, the elastic soft structure 33 covers the outer surface of the solidified structure 32 on the upper surface of all blocks of the preformed part 21, so that the thickness T1 of the outer ring block of the elastic soft structure 33 is greater than the thickness T2 of other blocks of the elastic soft structure 33; Step S300 and Step S400 are performed only once to form a single layer of elastic soft structure 33 covering the outer surface of the solidified structure 32 on the upper surface of all blocks of the preformed part 21.

In terms of structure, as shown in FIG6 , a single-layer elastic softening structure 33 covers the outer surface of the solidified structure 32 on the upper surface of all blocks of the body 31 .

In terms of efficacy, firstly, the elastic softening structure 33 can exert the elastic softening characteristics of the elastic softening polymer to soften the entire body 31, reduce the hardness of the entire body 31, and at the same time improve the elastic coefficient of the entire body 31. Furthermore, because the thickness T1 of the outer annular block of the elastic softening structure 33 is greater than the thickness T2 of other blocks of the elastic softening structure 33, the softening effect of the outer annular block of the main body 31 is better than the softening effect of other blocks of the main body 31, and the effect of improving the elastic coefficient of the outer annular block of the main body 31 is better than the effect of improving the elastic coefficient of other blocks of the main body 31. Therefore, the hardness of the outer annular block of the main body 31 is less than the hardness of other blocks of the main body 31, and the elastic coefficient of the outer annular block of the main body 31 is greater than the elastic coefficient of other blocks of the main body 31. Thus, the other blocks of the speaker vibration plate 30B have excellent fatigue resistance and elastic stretch recovery force, and the outer annular block of the speaker vibration plate 30B has better fatigue resistance and elastic stretch recovery force. The excellent fatigue resistance can make the speaker vibration plate 30B less likely to break, deform and fall off, and the excellent elastic recovery force can make the speaker vibration plate 30B have the effects of reducing resonance noise, reducing noise, making low-frequency channels easier to appear, and improving load rebound ability, thereby improving the output sound quality of the speaker. In terms of the performance of the above effects, the outer annular block of the speaker vibration plate 30B is better than other blocks of the speaker vibration plate 30B.

Example 3:

In terms of the method, the difference from the method of the second aspect of the first embodiment is that: (1) the materials of the elastic soft polymer 11 used in the two coatings in step S300 are different, the elastic soft polymer 11 coated for the first time is defined as an inner layer, and the elastic soft polymer 11 coated for the second time is defined as an outer layer; (2) in step S400, the inner layer of the elastic soft polymer 11 is dried to form an inner layer 331 of the elastic soft structure 33, and the outer layer of the elastic soft polymer 11 is dried to form an outer layer 332 of the elastic soft structure 33.

In terms of structure, as shown in FIG7 , the single-layer inner layer 331 covers the outer surface of the solidified structure 32 on the upper surface of the outer annular block of the body 31, and the single-layer outer layer 332 covers the outer surface of the solidified structure 32 on the upper surface of all blocks of the body 31.

In terms of efficacy, the difference from the efficacy of the second embodiment of the first embodiment is that the inner layer 331 and the outer layer 332 formed by drying two elastic softening polymers 11 of different materials can provide different softening effects and elasticity enhancement effects for the speaker vibration plate 30C.

Example 4:

In terms of the method, the difference from the method of the second aspect of the first embodiment is that: (1) the first coating of step S300 is to attach the elastic soft polymer 11 to the outer surface of the solidified structure 32 on the upper surface of the entire block of the preformed part 21, and the second coating of step S300 is to attach the elastic soft polymer 11 to the outer surface of the solidified structure 32 on the lower surface of the two local blocks of the outer annular block of the preformed part 21; (2) step S300 is to attach the elastic soft polymer 11 to the outer surface of the solidified structure 32 on the lower surface of the two local blocks of the outer ring block of the preformed part 21; The elastic soft polymer 11 used in the two coatings of step S300 is made of different materials. The elastic soft polymer 11 coated for the first time is defined as an upper layer, and the elastic soft polymer 11 coated for the second time is defined as a lower layer; (3) Step S400, the upper layer of the elastic soft polymer 11 is dried to form an upper layer 333 of the elastic soft structure 33, and the lower layer of the elastic soft polymer 11 is dried to form a lower layer 334 of the elastic soft structure 33.

In terms of structure, as shown in FIG8 , the single-layer upper layer 333 covers the outer surface of the solidified structure 32 on the upper surface of all blocks of the body 31, and the single-layer lower layer 334 covers the outer surface of the solidified structure 32 on the lower surface of two local blocks of the outer annular block of the body 31.

In terms of efficacy, the difference between the efficacy of the second embodiment and that of the first embodiment is that: (1) the softening effect of the two local blocks of the outer annular block of the main body 31 is better than the softening effect of the other blocks of the main body 31; (2) the effect of improving the elastic coefficient of the two local blocks of the outer annular block of the main body 31 is better than the effect of improving the elastic coefficient of the other blocks of the main body 31; (3) the upper layer 333 and the lower layer 334 formed by drying two elastic softening polymers 11 made of different materials can provide different softening effects and elasticity improvement effects to the speaker vibration plate 30D. Thus, the other areas of the speaker vibration plate 30D have excellent fatigue resistance and elastic stretch recovery force, and the two local areas of the outer annular area of the speaker vibration plate 30D have even better fatigue resistance and elastic stretch recovery force. The excellent fatigue resistance can make the speaker vibration plate 30D less likely to break, deform and fall off, and the excellent elastic recovery force can make the speaker vibration plate 30D have the effects of reducing resonance noise, reducing noise, making low-frequency channels easier to appear, and improving load rebound ability, thereby improving the output sound quality of the speaker. In terms of the performance of the above effects, the two local blocks of the outer annular block of the speaker vibration plate 30D have better effects than other blocks of the speaker vibration plate 30D.

Example 5:

In terms of the method, in step S300, the elastic soft polymer 11 is attached to the outer surface of the solidified structure 32 on the upper and lower surfaces of all blocks of the preformed part 21; in step S400, the elastic soft structure 33 covers the outer surface of the solidified structure 32 on the upper and lower surfaces of all blocks of the preformed part 21; step S300 and step S400 are performed only once to form a single layer of elastic soft structure 33 covering the outer surface of the solidified structure 32 on the upper and lower surfaces of all blocks of the preformed part 21.

In terms of structure, as shown in FIG9 , a single-layer elastic softening structure 33 covers the outer surface of the solidified structure 32 on the upper and lower surfaces of all blocks of the body 31 .

In terms of efficacy, the elastic softening structure 33 can bring into play the elastic softening characteristics of the elastic softening polymer, uniformly soften the entire body 31, uniformly reduce the hardness of the entire body 31, and uniformly increase the elastic modulus of the entire body 31. Thereby, the entire speaker vibration plate 30E has uniform and excellent fatigue resistance and elastic expansion and contraction recovery force. The uniform and excellent fatigue resistance can make the entire speaker vibration plate 30E less likely to break, deform and fall off. The uniform and excellent elastic recovery force can make the entire speaker vibration plate 30E have the effects of reducing resonance noise, reducing noise, making low-frequency channels easier to appear, and improving load rebound ability, thereby improving the output sound quality of the speaker.

Example 6:

In terms of the method, the difference from the method of the fifth aspect of the first embodiment is that the steps S300 and S400 are repeated multiple times to form multiple layers of elastic softening structures 33 covering all areas on the outer surface of the solidified structure 32.

In terms of structure, as shown in FIG10 , multiple layers of elastic softening structures 33 cover the outer surface of the solidified structure 32 on the upper and lower surfaces of all blocks of the body 31 .

In terms of efficacy, the multiple layers of elastic softening structure 33 can bring into play the elastic softening property of the elastic softening polymer, further uniformly soften the entire body 31, and at the same time further uniformly improve the elastic coefficient of the entire body 31, so that the hardness of the entire body 31 is less than the hardness of the entire body 31 of the fifth aspect of the first embodiment, and the elastic coefficient of the entire body 31 of the sixth aspect of the first embodiment is greater than the elastic coefficient of the entire body 31 of the fifth aspect of the first embodiment. Thus, compared with the speaker vibration plate 30E, the fatigue resistance and elastic expansion and contraction recovery of the speaker vibration plate 30F are more outstanding, the speaker vibration plate 30F is less likely to break, deform and fall off, and the speaker vibration plate 30F has more significant effects in reducing resonance noise, reducing noise, making low-frequency channels easier to appear, and improving load rebound ability, and the effect of improving the output sound quality of the speaker is better.

FIG11 is a flow chart of the second embodiment of the method of the present invention, and FIG12 is a schematic diagram of steps S100A to S400A of the second embodiment of the present invention. As shown in FIG11 and FIG12, the present invention provides a method for manufacturing a solidified and elastically softened speaker vibration plate, comprising the following steps:

Step S100A, a solidified polymer 10 is mixed with an elastic softened polymer 11 to prepare a composite polymer 12, the composite polymer 12 is attached to all areas of an outer surface of a substrate 20, and the substrate 20 has a plurality of preformed parts 21.

Step S200A, drying the substrate 20, so that the composite polymer 12 dries to form a composite structure 34 (see Figures 13 and 14), and the composite structure 34 covers the entire area of the outer surface of the substrate 20.

Step S100A and step S200A are performed only once or multiple times to form a single layer or multiple layers of composite structure 34 covering all areas on the outer surface of substrate 20.

Step S300A, heating and pressing the preformed parts 21 to form a plurality of speaker vibration plates 30.

Step S400A, separate the speaker vibration plates 30 from the substrate 20.

FIG. 13 and FIG. 14 are schematic diagrams of two states of the second embodiment of the speaker vibration plate 30 of the present invention. As shown in FIG. 13 and FIG. 14, the present invention provides a solidified and elastically softened speaker vibration plate 30G, 30H, including a body 31 and a composite structure 34. The single-layer or multi-layer composite structure 34 is formed by drying a composite polymer 12 and covers all blocks on an outer surface of the body 31. The composite polymer 12 is composed of a solidified polymer 10 and an elastically softened polymer 11.

The following will further illustrate the differences in methods, structures, and effects of the two aspects of the second embodiment with the help of diagrams.

Example 1:

In terms of method, only step S100A and step S200A are performed once to form a single-layer composite structure 34 covering all the blocks on the outer surface of the substrate 20. In terms of structure, as shown in FIG13 , the single-layer composite structure 34 covers all the blocks on the outer surface of the substrate 20. In terms of function, firstly, the composite structure 34 can exert the curing characteristics of the curing polymer to cure the entire body 31 and improve the hardness of the entire body 31, so that the speaker diaphragm 30 is able to generate vibrations under the operation of the voice coil. Furthermore, the composite structure 34 can bring into play the elastic softening property of the elastic softening polymer, uniformly soften the entire body 31, uniformly reduce the hardness of the entire body 31, and uniformly increase the elastic coefficient of the entire body 31. In this way, the speaker vibration plate 30G can obtain the same fatigue resistance and elastic recovery force as the speaker vibration plate 30E, thereby achieving the same effect.

Example 2:

In terms of method, steps S100B and S200B are repeated multiple times to form a plurality of layers of composite structures 34 covering all blocks on the outer surface of the substrate 20. In terms of structure, as shown in FIG14 , the plurality of layers of composite structures 34 cover all blocks on the outer surface of the substrate 20, so the thickness of the speaker diaphragm 30H is thicker than the thickness of the speaker diaphragm 30G. In terms of function, the speaker diaphragm 30H is exactly the same as the speaker diaphragm 30G.

In some embodiments, the curing polymer is a natural resin or a synthetic resin, and the elastic softening polymer is a natural rubber or a synthetic rubber. The curing properties of the curing polymer are the curing properties of the natural resin or the synthetic resin, and the elastic softening properties of the elastic softening polymer are the elastic softening properties of the natural rubber or the synthetic rubber.

In some embodiments, the elastic softening polymer is a solution of styrene butadiene rubber and water, and the concentration of styrene butadiene rubber is 1-80%. In other words, as long as the concentration of styrene butadiene rubber in the elastic softening polymer is 1-80%, it is sufficient to appropriately increase the elasticity of the substrate 20 and appropriately soften the substrate 20, and the effect is comparable to that of a pure styrene butadiene rubber solution (concentration of 100% and no water), but the styrene butadiene rubber content is less and the cost is lower.
