Description

Method for manufacturing elastic wave by using auxiliary material to assist impregnation
Technical Field
The present invention relates to a method for manufacturing an elastic wave of a horn, and more particularly, to a method for manufacturing an elastic wave by using an auxiliary material to assist the resin impregnation of a base material of the elastic wave.
Background
The loudspeaker comprises a shell, a magnet core, a voice coil, an elastic wave, a vibrating diaphragm and the like. The magnet core is arranged in the shell, the coil is wound on the outer surface of the voice coil to be connected with an external power supply, the magnet core is connected with the magnet core, electromagnetic induction is generated when current passes through the magnet core to vibrate up and down, and the elastic wave is connected with the shell and is provided with a central through hole to be connected with the voice coil. Each element being related to the tonal quality of the horn.
Among them, Damper (Damper) is one of the most important elements in the speaker structure, and the main functions of Damper are: (1) maintaining the voice coil at the correct position in the gap of the magnet core; (2) ensuring that the vibration system reciprocates axially when the voice coil is stressed; (3) providing a damping cushion as the voice coil vibrates; (4) the resonance efficiency of the loudspeaker is determined by the voice coil and the vibrating diaphragm of the damper and vibration system; and (5) preventing dust from entering the magnetic gap, etc.
The elastic wave with better elastic flexibility and toughness characteristics not only provides better output power and audio characteristics for the loudspeaker, but also is the basis for quality control when a loudspeaker manufacturer manufactures the loudspeaker, and simultaneously effectively prolongs the service life of the loudspeaker or the loudspeaker.
The existing method for manufacturing the elastic wave of the horn comprises the following steps: impregnation: impregnating a basic cloth material in the resin solution to enable the cloth material to absorb the resin and be cured, so that the cloth material has certain hardness; and (3) drying: moving the cloth material to a drying device for drying to remove the water in the cloth material; hot press molding: moving the cloth material to a hot-press forming device, and heating and pressurizing the horn elastic wave forming area on the cloth material by the hot-press forming device to enable the horn elastic wave forming area to shrink into a multi-ring annular wave structure; a cutting step: the horn spring shape is cut from the cloth material by a cutting device to obtain the finished horn spring.
However, the base material used for the conventional elastic wave often has various cases such as a difference in lot number of fiber material, a difference in fiber blending ratio, and a non-uniform yarn count weaving arrangement density, and when such a cloth material is used, the absorbency, stretchability, and bulkiness are slightly different from place to place. These local micro-differences may not cause significant problems for the substrate as a whole, but will affect the performance of subsequent processing of the cloth material. Particularly, when manufacturing an expensive and precise automobile horn, these differences affect the quality and quantity of the resin adsorbed by the base material in the resin impregnation step, and cause insufficient resin impregnated at each position of the base material or uneven distribution of the resin.
If the resin impregnated in the cloth material is insufficient, the elastic wave of the finished product is too soft, and proper vibration cannot be generated, so that the ideal sound quality effect cannot be output. If the resin impregnated in the cloth material is not uniformly distributed, the subsequent curing of the cloth material is not uniform, and further the strength of the elastic wave formed by hot pressing is irregular, so that the problem of unbalanced elastic wave vibration occurs during the use of the loudspeaker, and the output tone quality of the loudspeaker is affected.
Accordingly, the present inventors have found that the above-mentioned drawbacks require further improvement in the conventional method for manufacturing an elastic wave, and have made the present invention.

Detailed Description
Please refer to fig. 1 and fig. 2, which are a flowchart and a schematic diagram of a manufacturing method of a first embodiment of the present invention, respectively, and disclose a method for manufacturing an elastic wave using an auxiliary material to assist impregnation, the manufacturing method comprising the steps of:
a providing step S1, providing a substrate 10 and at least one auxiliary material 20.
The substrate 10 is a spring substrate that is processed in subsequent steps to form the spring of the horn. Please refer to fig. 3, which is a partially enlarged view of the substrate 10. The base material 10 is woven from a plurality of warp yarns 11 and a plurality of weft yarns 12, with a plurality of interstices, referred to herein as meshes 13, formed between the warp yarns 11 and the weft yarns 12. The warp yarns 11 and the weft yarns 12 are selected from one of polyester fibers, cotton fibers, acryl fibers, silk fibers, polyethylene naphthalate (PEN), Aramid fibers, bamboo fibers, or a combination thereof. Fig. 3 is only an example of the substrate 10 according to the first embodiment of the present invention, and the weaving manner of the substrate 10 is not limited thereto.
The auxiliary material 20 is a processing auxiliary fabric material, and the auxiliary base material 10 adsorbs the impregnation solution 31 in a processing step described later. In the present embodiment, as shown in the enlarged partial view of the sub material 20 in fig. 4A, the sub material 20 is formed by interlacing a plurality of warp yarns 21 and a plurality of weft yarns 22, and a plurality of gaps, referred to as meshes 23, are formed between the warp yarns 21 and the weft yarns 22. By adjusting the number of warp yarns 21 or weft yarns 22 arranged in a unit length, the fabric density of the auxiliary material 20 and the size of the mesh 23 can be adjusted. The pore diameter of the mesh 23 of the auxiliary material 20 may be selected from one or a combination of pore diameters larger than, equal to, and smaller than the mesh 13 of the base material 10.
The weaving pattern of the auxiliary material 20 of the present invention may be plain weave as shown in the present embodiment (fig. 4A) or leno weave as shown in fig. 4B, which is a partially enlarged schematic view of the auxiliary material 20 of another embodiment of the present invention. In this embodiment, two sets of warp yarns 21, i.e. two warp yarns, namely a ground warp 211 and a skein 212, are twisted with each other to form yarn holes, i.e. meshes 23. The twisted warp 212 is twisted on one side, such as the left side, of the ground warp 211, and then twisted on the other side, such as the right side, of the ground warp 211 after at least one (or three, five, etc.) weft insertion; the skein 212 is thus twisted with the ground warp 211 and interlaced with the weft yarns 22 to form meshes 23. The number ratio of ground warp 211 to twisted warp 212 required to form a mesh 23 is 1 in fig. 4B: 1, i.e. one ground warp 211 and one warp 212 are twisted with each other. However, the invention is not limited thereto, and the number ratio of ground warp 211 to warp 212 forming a mesh 23 may also be 2: 1. 2: 2, etc. Generally, if the number of warp yarns forming one mesh 23 is large, the mesh 23 is large and sparse; with a small number of warp threads, the mesh 23 is smaller and denser.
Fig. 4A and 4B are only examples of the auxiliary material 20 of the present invention, and the weaving manner of the auxiliary material 20 of the present invention is not limited thereto, as long as it forms a gap on the cloth.
A covering step S2, as shown in fig. 1 and 2, the covering step S2 is to cover the auxiliary material 20 on at least one surface of the substrate 10. In the present embodiment, an embodiment in which the pore diameter of the mesh 23 of the auxiliary material 20 is larger than the pore diameter of the mesh 13 of the base material 10 is taken as an example. Please refer to fig. 5 and fig. 6, which are an exploded view of the covering step S2 and a cross-sectional view of the auxiliary material 20 covering the substrate 10 in this embodiment, so as to show a state that the auxiliary material 20 covers the surface of the substrate 10. As shown in fig. 5 and 6, the covering step S2 is to attach and stack the auxiliary material 20 on one side surface of the substrate 10. However, the present invention is not limited thereto, and in the embodiment not shown, the number of the auxiliary materials 20 may be two, and the two auxiliary materials are respectively covered on the two side surfaces of the substrate 10.
As shown in fig. 6, in the present embodiment, since the mesh 23 of the auxiliary material 20 is larger than the mesh 13 of the substrate 10, one mesh 23 of the auxiliary material 20 can cover a plurality of meshes 13 of the substrate 10 at the same time.
It should be noted that in the covering step S2 of the present invention, the mesh 13 of the base material 10 and the mesh 23 of the auxiliary material 20 are at least partially disposed in a staggered manner. Referring to fig. 7, which is a top view of fig. 6, it shows that after the covering step S2, some of the warp yarns 11 and the weft yarns 12 of the base material 10 are exposed from the meshes 23 of the auxiliary material 20, and the warp yarns 21 and the weft yarns 22 on one side of the auxiliary material 20 also cover or cross over some of the meshes 13 of the base material 10.
An impregnation step S3, immersing the substrate 10 and the auxiliary material 20 in an impregnation solution 31, so that both the substrate 10 and the auxiliary material 20 absorb the impregnation solution 31. The impregnation step S3 is performed before or after the covering step S2. In the present embodiment, taking the step S3 of impregnation after the step S2 of covering as an example, as shown in fig. 1 and 2, after the auxiliary material 20 is covered on one surface of the substrate 10, the substrate 10 and the auxiliary material 20 are immersed in an impregnation solution 31, so that both the substrate 10 and the auxiliary material 20 absorb the impregnation solution 31. In the present embodiment, the impregnation solution 31 is installed in a tank 30.
In the impregnation step S3, the substrate 10 adsorbs the impregnation solution 31 in the tank 30, and the substrate 10 further adsorbs the impregnation solution 31 attached to the auxiliary 20, particularly the impregnation solution 31 attached to the mesh 23, from the auxiliary 20.
The impregnation solution 31 mainly includes a liquid resin, and the liquid resin is selected from one of phenolic resin, epoxy resin, and polyester resin, or a combination thereof. The base material 10 absorbed with the liquid resin may have a certain hardness after it is solidified. Preferably, the impregnation solution 31 further includes one or a combination of a water repellent and a flame retardant, so that the substrate 10 further has the effects of water repellency, oil repellency, stain resistance, flame retardancy/flame retardancy, and the like.
A standing step S4, removing the impregnated substrate 10 and auxiliary material 20 from the impregnation solution 31, and standing for a solidification time to make the degree of solidification of the impregnation solution 31 absorbed by the substrate 10 and auxiliary material 20 reach 10 to 50%, preferably 25 to 35%. During the standing step S4, the substrate 10 also further adsorbs the impregnation solution 31 on the auxiliary material 20, particularly the impregnation solution 31 adsorbed on the mesh 23 in the impregnation step S3. The standing step S4 may be performed under a normal temperature environment. The setting time is from 1 to 12 hours, preferably from 6 to 10 hours.
A separation step S5, separating the auxiliary material 20 from the base material 10. The auxiliary material 20 can be recovered for reuse. The substrate 10 continues to be processed.
A molding step S6, hot press molding the base material 10. In this embodiment, the substrate 10 is further heated, pressurized and molded by a hot pressing method through a hot pressing mold 50. The cross section of the molded substrate 10 is formed in a wavy shape.
A cutting step S7, cutting the substrate 10 after hot press forming into at least one elastic wave 100. In the present embodiment, a cutting device 60 is further used to cut the substrate 10, and then a damper 100 is obtained. The damper 100 may be a disc-shaped damper 100 as shown in fig. 8, but the damper 100 may be rectangular or other shapes.
For a further understanding of the nature of the structures, uses of technical means, and intended effects of the invention, reference should now be made to the use of the present invention, from which it is believed that a more thorough and detailed understanding of the invention may be obtained, as follows:
please refer to fig. 1 and fig. 2, which are also shown in fig. 5 to fig. 6. In the manufacturing method of the present invention, besides providing the substrate 10, at least one auxiliary material 20 is further provided, and the auxiliary material 20 is covered on a surface of the substrate 10 (covering step S2). The covering step S2 is performed before or after the impregnation step S3.
In the case that 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 covering the substrate 10 increases after the auxiliary material adsorbs the impregnation solution 31, and the gravity generated by the weight acts on the substrate 10 and the impregnation solution 31 to apply pressure, so that the impregnation solution 31 adsorbed on the surface of the substrate 10 is pressed and can more easily enter the substrate 10. Even during the standing step S4 after the auxiliary material 20 and the substrate 10 are removed from the impregnation solution 31, the substrate 10 can continuously adsorb the impregnation solution 31 adhered to the both side surfaces of the auxiliary material 20 or the meshes 23 thereof due to the above-mentioned gravity.
In the case where the covering step S2 is performed after the impregnation step S3, the substrate 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 on at least one surface of the substrate 10 impregnated with the impregnation solution 31. Thus, in the present invention, the impregnation solution 31 is sufficiently adsorbed on both surfaces of the auxiliary material 20 in addition to both surfaces of the base material 10. That is, the present invention utilizes the extra surface provided by the auxiliary material 20 to increase the surface area of the cloth material that absorbs the impregnation solution 31 in the impregnation step S3. Specifically, in the conventional elastic wave manufacturing method, only the base material of the elastic wave is provided for the impregnation solution in the impregnation step, and the surface area of the cloth material capable of adsorbing the impregnation solution is limited to the two side surfaces of the base material; however, the method of the present invention increases the surface area of the fabric material, and allows significantly more impregnation solution 31 to be adsorbed in impregnation step S3.
In addition, the mesh 23 of the auxiliary material 20 provided in this embodiment is larger than the mesh 13 of the base material 10, that is, the cloth gap of the auxiliary material 20 is larger than that of the base material 10. In general, the smaller the pores of the fabric, the more difficult the molecules of the impregnation solution 31 pass through. Therefore, the conventional method for producing an elastic wave is likely to cause the impregnation solution to adhere to the surface of the cloth and not to enter the inside of the cloth from the gap of the cloth, and therefore, it takes a long time to cause the molecules of the impregnation solution to enter the inside of the cloth. In this embodiment, the auxiliary material 20 with large gaps is stacked on the base material 10, so as to temporarily increase the pore diameter of the gaps on the surface of the cloth material, and the molecules of the impregnation solution 31 can more easily penetrate through the meshes 23 of the auxiliary material 20. In addition, the auxiliary material 20 also provides a guiding function, after the impregnation solution 31 is guided to pass through the auxiliary material 20 with a larger aperture, the impregnation solution enters the gap of the base material 10 with a smaller aperture, and is adsorbed on the yarn from the inside of the base material 10. Thereby, the impregnation solution 31 can reach the inside of the substrate 10 in a shorter time, and the surface and the inside of the substrate 10 can adsorb enough impregnation solution 31.
It should be noted that, no matter whether the aperture of the mesh 23 of the auxiliary material 20 is larger than, equal to or smaller than the aperture of the mesh 13 of the base material 10, in the present invention, as shown in fig. 7, by disposing the mesh 13 of the base material 10 and the mesh 23 of the auxiliary material 20 at least partially in a staggered manner, the impregnation solution 31 passing through the mesh 23 from one side of the auxiliary material 20 can be directly adsorbed by the yarn fiber of the base material 10 located at the other side of the auxiliary material 20. Similarly, the impregnation solution 31 passing through the mesh 13 from one side of the base material 10 may be directly adsorbed by the yarn fibers of the auxiliary material 20 positioned on the other side of the base material 10. By such staggered arrangement of the fabric yarn and the gaps, the base material 10 and the auxiliary material 20 are engaged with each other, so that the whole fabric can absorb more impregnation solution 31 in a short time in the impregnation step S3. Further, during the standing step S4, the substrate 10 can also pass through the impregnation solution 31 adhering to the auxiliary material 20, and further adsorption of the impregnation solution 31 can be continued.
Please refer to fig. 9, which is a flowchart illustrating a manufacturing method according to a second embodiment of the present invention. The second embodiment is different from the first embodiment in that the second embodiment has a dewatering step S8 and an optional drying step S9.
The dehydration step S8 is to dehydrate the auxiliary material 20 and the substrate 10 to remove excess water in the auxiliary material 20 and the substrate 10. The time of the dehydration step S8 is 5 to 60 minutes, preferably 7 to 12 minutes. Therefore, the drying time of the auxiliary material 20 and the base material 10 can be accelerated, and the operation time required by the drying step can be further reduced. Meanwhile, the present embodiment can also achieve the effects of the first embodiment.
In the drying step S9, the impregnation solution 31 on the substrate 10 that is not completely solidified is dried by a drying device (not shown). The drying step S9 makes the solidification degree of the impregnation solution 31 reach 60 to 90%, preferably 70 to 80%, so that the overall structure of the substrate 10 has 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 subsidiary material 20 and the base material 10 are dehydrated together; the drying step S9 is selectively performed, and if the drying step S9 is selectively performed, the drying step S9 is performed before the forming step S6, so that the substrate 10 is suitable for press forming.
In yet another embodiment, the dehydration step S8 is performed after the separation step S5, as shown in fig. 10, to separately dehydrate the base material 10.
It should be noted that, in an embodiment not shown in the drawings, the method for manufacturing an elastic wave using an auxiliary material to assist impregnation of the elastic wave of the present invention may further include a step of re-impregnation, which is performed between the step of impregnation S3 and the step of standing S4. In the secondary impregnation step, the supplement material 20 and the base material 10 after the impregnation step S3 are wound into a bundle of two-layer materials in a state where the supplement material 20 is covered on the base material 10, and then placed in the tank 30 to further adsorb the impregnation solution 31. Thus, in the present invention, in addition to the gravity generated by the auxiliary material 20 covering the substrate 10, the extrusion force is applied to the impregnation solution 31 attached to the substrate 10 and the auxiliary material 20 by the winding and bundling method, so that the impregnation solution 31 can more easily enter the substrate 10 by the gravity and the extrusion; meanwhile, the base material 10 and the auxiliary material 20 can continuously adsorb the impregnation solution 31 in the tank 30.
The features of the present invention and the expected effects that can be achieved are set forth below:
the method for manufacturing the elastic wave by using the auxiliary material to assist the impregnation mainly comprises the steps of covering the auxiliary material 20 on the base material 10 of the elastic wave 100, and soaking the base material 10 and the auxiliary material 20 in the impregnation solution 31 together, so that the amount of resin adsorbed by the base material 10 is increased, and the resin is uniformly 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, the service life of the loudspeaker can be prolonged, and the loudspeaker can output better sound quality.
Therefore, the invention has the following implementation efficacy and technical efficacy:
first, the present invention provides the auxiliary material 20 outside the base material 10, so that the surface area capable of adsorbing the impregnation solution 31 is increased, and the cloth material can adsorb more resin, so that the formed elastic wave 100 has excellent toughness and hardness performance.
Secondly, in the present invention, the auxiliary material 20 is used, so that the impregnation solution 31 can be uniformly adsorbed on the surface and inside of the base material 10, and the impregnation solution 31 can be adsorbed to the inside of the base material 10 in a short time, thereby reducing the time cost required for manufacturing the damper 100.
Thirdly, through the installation of the auxiliary material 20 of the present invention, even if the base material 10 is removed from the tank 30 and left standing, the base material 10 can still continuously adsorb the impregnation solution 31 attached to the auxiliary material 20, thereby shortening the time that the cloth material needs to be placed in the tank 30, and thus, increasing the production efficiency in time unit.
Fourthly, the auxiliary material 20 with larger gaps of the cloth material is utilized, and the impregnation solution 31 is easier to be absorbed compared with the base material 10 with smaller gaps of the cloth material, so that the absorption probability of the impregnation solution 31 is increased.
Fifthly, the invention can improve the adsorption efficiency of the impregnation solution 31 by the staggered arrangement of the meshes 13 of the base material 10 and the meshes 23 of the auxiliary material 20.
Sixth, the impregnation solution of the present invention further comprises a water-repellent agent and a flame retardant agent, so that the water-repellent treatment and the flame retardant treatment are integrated with the impregnation step S3, the overall processing time of the elastic wave 100 is saved, and the elastic wave 100 further has the effects of water-repellent property, oil-repellent property, stain resistance, flame retardancy/flame resistance, etc.
In summary, the present invention has been made in an extremely practical and advanced manner in the same kind of products, and the same structure is not found in the literature after looking up the technical data about such structure at home and abroad, so that the present invention has been provided with the patent requirements and the application is made through the appended method.
