Description

Using auxiliary materials to assist impregnated elastic wave manufacturing method

The invention relates to a method for manufacturing elastic waves of a horn, in particular to a method for manufacturing elastic waves in which a base material impregnated with a resin to assist elastic waves is impregnated with resin.

The structure of the speaker includes the shell, magnet core, voice coil, elastic wave, diaphragm and so on. The magnet core is set in the shell, and the outer surface of the voice coil is wound with a coil to connect to an external power source and connected to the magnet core. When the current passes, electromagnetic induction is generated to vibrate up and down. The elastic wave is connected to the shell and has a central through hole to connect the sound ring. Each component is related to the sound quality of the speaker.

Among them, the elastic wave (Damper) is one of the most important components in the structure of the speaker. The main functions of the elastic wave are: (1) to maintain the correct position of the voice coil in the gap of the magnet core; (2) to ensure that the voice coil is under force , The vibration system reciprocates in the axial direction; (3) Provides damping buffer with the vibration of the voice coil; (4) The elastic wave and the voice coil and diaphragm of the vibration system jointly determine the resonance efficiency of the horn; and (5) Prevent dust Enter the magnetic gap, etc.

The elastic wave with better elasticity and toughness characteristics, in addition to providing better output power and audio characteristics of the speaker, is also the basis for the quality control of the speaker manufacturer when manufacturing the speaker, while effectively increasing the service life of the speaker or speaker.

The conventional elastic wave manufacturing method of a speaker includes: an impregnation step: impregnating a basic cloth material with a resin solution, so that the cloth material absorbs the resin and solidifies, and has a certain hardness; the drying step: the cloth material is moved to a drying device It is dried to remove the moisture in the cloth; hot press forming step: the cloth is moved to a hot press forming device, which is heated and pressurized in the horn elastic wave forming area on the cloth to make the horn elastic wave formed The area is shrunk into a ring-shaped wave structure with a plurality of circles; cutting step: using a cutting device to cut the shape of the horn elastic wave from the cloth material to obtain the completed horn elastic wave.

However, the substrates used in the elastic wave generated by the conventional technology often have different situations such as different batch numbers of fiber raw materials, different fiber blending rates, and uneven density of yarn support weaving. When using such a cloth material, its absorption everywhere The degree, flexibility, and bulkiness will be slightly different. These local slight differences may not cause obvious problems for the overall base fabric, but will affect the performance of the subsequent processing of the cloth material. Especially when manufacturing elastic waves of high-priced and precise car speakers, these differences will affect the quality and quantity of the resin adsorbed by the substrate in the resin impregnation step, resulting in insufficient or uneven distribution of the resin impregnated throughout the substrate.

If the resin impregnated on the cloth material is insufficient, it is easy to cause the elastic wave of the finished product to be too soft, and it cannot generate proper vibration, so that it cannot output the ideal sound quality effect. If the distribution of the impregnated resin in the cloth is uneven, the subsequent curing of the cloth will be uneven, which will result in irregular strength of the elastic wave formed by hot pressing, and the problem of imbalance of elastic wave vibration in the use of the speaker will affect The sound quality of the speaker output.

Please refer to FIGS. 1 and 2, which are a flowchart of a manufacturing method and a schematic diagram of a manufacturing process according to a first embodiment of the present invention, respectively, which discloses a method of manufacturing an elastic wave using auxiliary materials to assist impregnation. The steps of the manufacturing method include:

In a providing step S1, a base material 10 and at least one auxiliary material 20 are provided.

The substrate 10 is an elastic wave substrate, which is processed in a subsequent step to form an elastic wave of the speaker. Please also refer to FIG. 3, which is a partially enlarged schematic view of the substrate 10. The base material 10 is formed by interlacing a plurality of warp yarns 11 and a plurality of weft yarns 12, and a plurality of gaps are formed between the warp yarns 11 and the weft yarns 12, referred to herein as a mesh 13. The warp yarn 11 and the weft yarn 12 are selected from polyester fiber, cotton fiber, acrylic fiber, silk fiber, polyethylene naphthalate (PEN), phenylamide fiber (Aramid), bamboo fiber One or a combination thereof. FIG. 3 is only an example of the substrate 10 of the first embodiment of the present invention, and the weaving method of the substrate 10 of the present invention is not limited thereto.

The auxiliary material 20 is a processing auxiliary cloth material, and the auxiliary base material 10 absorbs the impregnating solution 31 in a processing step described later. The auxiliary material 20, in this embodiment, as shown in a partially enlarged schematic view of the auxiliary material 20 in FIG. 4A, is composed of a plurality of warp yarns 21 and a plurality of weft yarns 22 interlaced to weave. These warp yarns 21 and A plurality of gaps are formed between the weft yarns 22, which is referred to herein as a mesh 23. By adjusting the number of warp yarns 21 or weft yarns 22 arranged per unit length, the fabric density of the auxiliary material 20 and the size of the mesh 23 can be adjusted. The pore diameters of the meshes 23 of the auxiliary material 20 may be selected from one or a combination of pore diameters greater than, equal to, and smaller than those of the mesh pores 13 of the base material 10.

The weaving method of the auxiliary material 20 of the present invention may be a plain weave structure as shown in this embodiment (FIG. 4A) or a leno structure, as shown in FIG. 4B, which is an auxiliary material 20 of another embodiment of the present invention A partially enlarged schematic view. In this embodiment, it uses two sets of warp yarns 21, that is, two kinds of warp yarns, ground warp 211 and twisted warp 212, which are twisted with each other to form a yarn hole, or mesh 23. The warp 212 is first twisted on one side of the ground warp 211, such as the left side, and after at least one (or three, five, etc.) weft insertions, it is twisted to the other side of the ground warp 211, such as the right side; The ground warp 211 is twisted with each other and interwoven with the weft yarn 22 to form a mesh 23. The number of ground warps 211 and twisted warps 212 required to form a mesh 23 is 1:1 in FIG. 4B, that is, one ground warp 211 and one twisted warp 212 are twisted with each other. However, the present invention is not limited to this, and the ratio of the number of ground warps 211 and twisted warps 212 forming a mesh 23 may be 2:1, 2:2, etc. Generally speaking, if the number of warp yarns forming a mesh 23 is large, the mesh 23 is large and sparse; if the number of warps is small, the mesh 23 is small and dense.

4A and 4B are only examples of the auxiliary material 20 of the present invention, and the weaving method of the auxiliary material 20 of the present invention is not limited to this, as long as it forms a gap in the cloth material.

A covering step S2, as shown in FIGS. 1 and 2, the covering step S2 is to cover the auxiliary material 20 on at least one surface of the base material 10. In this embodiment, an embodiment in which the pore size of the mesh 23 of the auxiliary material 20 is larger than the pore size of the mesh 13 of the base material 10 is taken as an example. Please refer to FIGS. 5 and 6 at the same time, which is an exploded schematic view of the covering step S2 and a cross-sectional schematic view of the auxiliary material 20 covering the base material 10 in this embodiment, to show the state of the auxiliary material 20 covering the surface of the base material 10. As shown in FIGS. 5 and 6, in the covering step S2, the auxiliary material 20 is attached and stacked on one side surface of the base material 10. However, the present invention is not limited to this. In the embodiment (not shown), the number of the auxiliary materials 20 may be two, respectively covering both sides of the substrate 10.

As shown in FIG. 6, in this embodiment, since the mesh 23 of the auxiliary material 20 is larger than the mesh opening 13 of the base material 10, one mesh 23 of the auxiliary material 20 can be simultaneously covered to include a plurality of nets of the base material 10孔13.

It is worth noting that in the covering step S2 of the present invention, the meshes 13 of the base material 10 and the meshes 23 of the auxiliary material 20 are at least partially misaligned. Please refer to FIG. 7, which is a top view of FIG. 6, which shows that after covering step S2, part of the warp yarns 11 and weft yarns 12 of the base material 10 are exposed from the mesh 23 of the auxiliary material 20, and the warp on the auxiliary material 20 side The yarn 21 and the weft yarn 22 also cover or traverse a part of the mesh 13 of the base material 10.

In an impregnation step S3, the base material 10 and the auxiliary material 20 are impregnated in an impregnation solution 31, so that both the base material 10 and the auxiliary material 20 adsorb the impregnation solution 31. The impregnation step S3 is performed before or after the covering step S2. In this embodiment, taking the impregnation step S3 after the covering step S2 as an example, as shown in FIGS. 1 and 2, after covering the auxiliary material 20 on a surface of the base material 10, the base material 10 and the auxiliary material 20 is impregnated together in an impregnation solution 31, so that both the base material 10 and the auxiliary material 20 adsorb the impregnation solution 31. In this embodiment, the impregnation solution 31 is installed in a tank 30.

In the impregnation step S3, in addition to the impregnation solution 31 in the adsorption tank 30, the base material 10 further adsorbs the impregnation solution 31 that has been attached to the auxiliary material 20 from the auxiliary material 20, especially has been attached to the meshes 23's impregnating solution 31.

The impregnating solution 31 mainly includes a liquid resin selected from one or a combination of phenol resin, epoxy resin, and polyester resin. The substrate 10 to which the liquid resin is adsorbed may have a certain hardness after it is solidified. Preferably, the impregnating solution 31 further includes one or a combination selected from a water repellent agent and a flame retardant agent, so that the substrate 10 further has the effects of water repellency, oil repellency, antifouling, flame retardant/flame resistance, and the like.

In a static step S4, the impregnated base material 10 and the auxiliary material 20 are taken out of the impregnating solution 31 and allowed to stand for a solidification time, so that the degree of solidification of the impregnating solution 31 adsorbed by the base material 10 and the auxiliary material 20 reaches 10 to 50%, preferably 25 to 35%. During the standing step S4, the substrate 10 also simultaneously absorbs the impregnation solution 31 on the auxiliary material 20, especially the impregnation solution 31 that has been adsorbed on the meshes 23 in the impregnation step S3. The standing step S4 can be performed under a normal temperature environment. The setting time is 1 to 12 hours, preferably 6 to 10 hours.

In a separation step S5, the auxiliary material 20 is separated from the base material 10. The auxiliary material 20 can be recycled for reuse. The substrate 10 continues to be processed.

In a molding step S6, the substrate 10 is subjected to hot press molding. In this embodiment, it further heats, pressurizes and shapes the substrate 10 through a hot-pressing mold 50 in a hot-pressing manner. The cross-section of the base material 10 after molding is wavy.

In a cutting step S7, the substrate 10 after hot press molding is cut into at least one elastic wave 100. In this embodiment, a cutting device 60 is further used to cut the substrate 10, and then an elastic wave 100 is obtained. The shape of the elastic wave 100 may be a disk-shaped elastic wave 100 as shown in FIG. 8, but it is not limited thereto, and the shape of the elastic wave 100 may also be a rectangle or other shapes.

In order to further understand the structural features of the present invention, the use of technical means and the expected effect, the way of using the present invention is described here. It is believed that this can provide a more in-depth and specific understanding of the present invention, as follows:

Please refer to FIG. 1 and FIG. 2 again, in conjunction with FIGS. 5 to 6. In the manufacturing method of the present invention, in addition to providing the base material 10, at least one auxiliary material 20 is additionally provided, and the auxiliary material 20 is covered on a surface of the base material 10 (covering step S2). The covering step S2 is performed before or after the impregnation step S3.

In the present invention, when the covering step S2 is performed before the impregnation step S3, as in the first embodiment, in the impregnation step S3, the weight of the auxiliary material 20 covered on the base material 10 increases after the impregnation solution 31 is adsorbed, which causes Gravity acts on the base material 10 and the impregnating solution 31 to apply pressure, so that the impregnating solution 31 adsorbed on the surface of the base material 10 is compressed and enters the base material 10 more easily. Even during the standing step S4 after the auxiliary material 20 and the base material 10 are removed from the impregnating solution 31, the base material 10 can continue to adsorb the surface or both sides of the auxiliary material 20 due to the gravity NET 23 of the impregnating solution 31.

When the covering step S2 is performed after the impregnation step S3, the base material 10 and the auxiliary material 20 are respectively impregnated with the impregnation solution 31, and then the auxiliary material 20 impregnated with the impregnation solution 31 is covered with the base material 10 impregnated with the impregnation solution 31 At least one surface. In this way, in addition to the two sides of the base material 10, the two sides of the auxiliary material 20 also absorb sufficient impregnation solution 31 in the present invention. That is, the present invention uses the additional surface provided by the auxiliary material 20 to increase the surface area of the cloth material to absorb the impregnation solution 31 in the impregnation step S3. Specifically, in the conventional elastic wave manufacturing method, in the impregnation step, only the substrate of the elastic wave is provided for the impregnation solution, and the surface area of the cloth material that can absorb the impregnation solution is limited to the surfaces of both sides of the substrate; The method increases the surface area of the cloth material, and can significantly absorb more impregnation solution 31 in the impregnation step S3.

In addition, the mesh 23 of the auxiliary material 20 provided in this embodiment is larger than the mesh opening 13 of the base material 10, that is, the cloth material gap of the auxiliary material 20 is larger than the base material 10. In general, the smaller the gap of the cloth material, the more difficult it is for the molecules of the impregnation solution 31 to penetrate. Therefore, the conventional elastic wave manufacturing method is easy to attach the impregnating solution to the surface of the cloth, and it is not easy to enter the interior of the cloth from the gap of the cloth. Therefore, it takes more time for the molecules of the impregnating solution to enter the interior of the cloth . In this embodiment, the auxiliary material 20 with a large gap is stacked on the base material 10 to temporarily increase the pore diameter of the surface of the cloth material, so that the molecules of the impregnating solution 31 can easily pass through the mesh 23 of the auxiliary material 20. In addition, the auxiliary material 20 also provides a guiding function. After guiding the impregnating solution 31 through the auxiliary material 20 with a larger pore diameter, it enters the gap of the base material 10 with a smaller pore diameter, and is absorbed onto the yarn from the inside of the base material 10 . In this way, the impregnation solution 31 can reach the interior of the base material 10 in a relatively short time, and allows the surface and the interior of the base material 10 to adsorb sufficient impregnation solution 31.

It is worth mentioning that, regardless of whether the pore size of the mesh 23 of the auxiliary material 20 is greater than, equal to or smaller than the pore size of the mesh 13 of the base material 10, in the present invention, as shown in FIG. The holes 13 are at least partially misaligned with the mesh 23 of the auxiliary material 20. The impregnating solution 31 passing through the mesh 23 from one side of the auxiliary material 20 can be directly made from the yarn fiber of the base material 10 on the other side of the auxiliary material 20 Adsorbed. Similarly, the impregnating solution 31 passing through the mesh 13 from one side of the base material 10 may be directly absorbed by the yarn fiber of the auxiliary material 20 located on the other side of the base material 10. Through the misaligned arrangement of the cloth material yarn and the gap, the base material 10 and the auxiliary material 20 cooperate with each other, so that the entire cloth material can absorb more impregnation solution 31 in a short time in the impregnation step S3. Furthermore, during the standing step S4, the base material 10 can also penetrate the impregnation solution 31 adhering to the auxiliary material 20, and the adsorption of the further impregnation solution 31 can be continued.

Please continue to refer to FIG. 9, which is a flowchart of the manufacturing method of the second embodiment of the present invention. Compared with the first embodiment, the second embodiment differs in that the second embodiment has an additional dehydration step S8 and optionally a drying step S9.

In the dehydration step S8, the auxiliary material 20 and the base material 10 are dehydrated to remove excess water in the auxiliary material 20 and the base material 10. The time of the dehydration step S8 is 5 to 60 minutes, preferably 7 to 12 minutes. Thereby, the drying time of the auxiliary material 20 and the base material 10 can be accelerated, thereby further reducing the working time required for the drying step. At the same time, this embodiment can also achieve the effects of the first embodiment.

In the drying step S9, the impregnation solution 31 on the substrate 10 that has not been completely solidified is dried through a drying device (not shown). In the drying step S9, the degree of solidification of the impregnating solution 31 reaches 60 to 90%, preferably 70 to 80%, and the overall structure of the substrate 10 has a certain elasticity, toughness and strength.

In this embodiment, as shown in FIG. 9, the dehydration step S8 is performed before the separation step S5, and the auxiliary material 20 and the base material 10 are dehydrated together; and the drying step S9 is selectively performed, and the drying step is selected In the case of S9, the drying step S9 is performed before the molding step S6 to make the base material 10 suitable for press molding.

In still another embodiment, as shown in FIG. 10, the dehydration step S8 is performed after the separation step S5 to dehydrate the base material 10 alone.

It is worth noting that in an embodiment not shown, the elastic wave manufacturing method using auxiliary materials to assist impregnation of the present invention may further include a re-impregnation step, which is between the impregnation step S3 and the standing step S4 Between. In the re-impregnation step, the auxiliary material 20 and the base material 10 after the impregnation step S3 are wound into a bundle of double-layer materials with the auxiliary material 20 covering the base material 10, and then placed in the tank 30 to further Absorbing impregnating solution 31. In this way, in addition to the gravity generated by the auxiliary material 20 covering the base material 10, the present invention also squeezes the impregnating solution 31 attached to the base material 10 and the auxiliary material 20 by the method of winding into a bundle The pressure further causes the impregnation solution 31 to enter the interior of the base material 10 more easily by gravity and squeeze; at the same time, the base material 10 and the auxiliary material 20 can also continuously absorb the impregnation solution 31 in the tank 30.

Hereby, the characteristics of the present invention and the achievable expected effects are stated as follows:

The method of manufacturing an elastic wave using auxiliary materials to assist impregnation in the present invention mainly includes covering the auxiliary material 20 on the base material 10 of the elastic wave 100, and immersing the base material 10 and the auxiliary material 20 in the impregnating solution 31 together In this way, the amount of resin absorbed by the base material 10 is increased, and the resin is evenly distributed on the surface and inside of the base material 10, so that the finished elastic wave 100 has better structural strength and fatigue resistance, and can extend the service life of the speaker and Let the speaker output better sound quality.

Therefore, the present invention has the following implementation and technical effects:

First, the present invention provides an auxiliary material 20 outside the base material 10, which increases the surface area capable of adsorbing the impregnating solution 31, so the cloth material can adsorb more resin, so that the elastic wave 100 after molding has a more excellent toughness, Hardness performance.

Second, the use of the auxiliary material 20 of the present invention not only enables the surface and the interior of the base material 10 to uniformly adsorb the impregnation solution 31, but also adsorbs the impregnation solution 31 to the interior of the base material 10 in a shorter time, reducing manufacturing The cost of time required for Bomb 100.

Third, through the arrangement of the auxiliary material 20 of the present invention, even if the base material 10 is removed from the tank 30 and left to stand, the base material 10 can continue to adsorb the impregnating solution 31 attached to the auxiliary material 20, shortening the need for the cloth material The time placed in the tank 30 increases the production efficiency in the time unit.

Fourthly, the present invention utilizes the auxiliary material 20 having a large gap in the cloth material, which is easier to allow the impregnation solution 31 to adsorb than the base material 10 having a smaller gap in the cloth material, thereby increasing the adsorption probability of the impregnation solution 31.

Fifth, in the present invention, the meshes 13 of the base material 10 and the meshes 23 of the auxiliary material 20 are arranged in a misaligned manner, which can improve the adsorption efficiency of the impregnating solution 31.

Sixth, the impregnation solution of the present invention also includes a water repellent agent and a flame retardant agent, so that the water repellent treatment and the flame retardant treatment are combined with the impregnation step S3 to save the overall processing time of the elastic wave 100 and make the elastic wave 100 It further has the effects of water repellency, oil repellency, anti-fouling, flame retardant/flame resistance, etc.

To sum up, the present invention has its excellent advancement and practicality in similar products. At the same time, it has searched the technical information about this kind of structure at home and abroad, and the same structure has not been found in the literature. Therefore, The present invention already possesses the essentials of the invention patent, and the application is filed according to law.
