Description
Technical Field
The present invention relates to a method for manufacturing an elastic wave for a speaker, and more particularly, to a method for manufacturing an elastic wave with an elastic support structure after molding.
Background
Accordingly, many non-metal component substrates included in a conventional speaker or loudspeaker are made of cloth materials, and the main reason is that the specially processed cloth materials have appropriate elasticity and strength to provide the required functions for the operation of the speaker or loudspeaker, such as the vibration plates of drum paper, elastic wave, connecting sheet …, etc. The Damper (Damper) is one of the most important components in a speaker or a loudspeaker structure, and the Damper is an elastic support between the outer frame and the voice coil, and has the main functions of providing a restoring force required by the voice coil during vibration of the vibrating plate, and restraining the displacement of the voice coil in the horizontal direction, so that the vibration process of the voice coil is more stable. Therefore, in addition to providing better output power and audio characteristics of the speaker or loudspeaker, the damper is also the basis for quality control when the speaker or loudspeaker manufacturer manufactures the speaker or loudspeaker.
The prior art method for manufacturing elastic waves comprises an impregnation step, a baking step, a hot pressing step and a cutting step. The impregnation step is to impregnate the cloth into the resin, so that the cloth absorbs the resin, and a resin layer is formed outside the fibers of the cloth, so that the cloth has certain hardness. And the baking step is to dry the cloth absorbing the resin so as to remove the moisture in the cloth. The hot pressing step is to heat the cloth absorbing the resin and to form a wave-like shape on the cross section in a stamping mode. And the cutting step is to form a central through hole, cut the central through hole into a plurality of elastic waves and remove redundant cloth.
Further, the structure of the damper made by the above-mentioned conventional technique has the following disadvantages: first, the hardness of the whole damper is the same, and the dried resin is hard and has poor elasticity. Secondly, when the elastic wave is used for a long time, the resin is subjected to vibration, fatigue stress, heat and the like, and problems such as hardening and aging may occur. Thirdly, because the resin material is different from the fabric, the resin material is easy to generate resonance noise with the vibration frequency of the fabric, thereby having the defects of more noise, difficult appearance of low-frequency sound channels, poor load resilience and poor tone quality.
Therefore, the inventors of the present invention have observed the above-mentioned shortcomings and have considered that further improvement of the existing elastic wave structure is still necessary, and have made the present invention.

Preferably, in the elastic disposing step, at least two elastic supporting portions are disposed on the wavy portion, and the elastic supporting portions are linearly disposed in a radial direction of the elastic wave.
Preferably, in the elastic disposing step, a plurality of the elastic support portions are disposed at the wavy portion in a manner of being spaced apart from each other in a circumferential direction or a radial direction.

Detailed Description
Please refer to fig. 1, fig. 2 and fig. 3, which are a block flow diagram, a flow chart and an appearance perspective view of the generated damper according to the first embodiment of the present invention, and disclose a damper manufacturing method for forming an elastic support structure, comprising:
a providing step S110, providing a substrate 10. The substrate 10 is an original fabric of the damper 100, and is processed in a subsequent step to form the damper 100 of the horn. Specifically, the base material 10 is formed by interweaving a plurality of warp yarns and a plurality of weft yarns; the warp and weft yarns may be selected from one or a combination of polyester fibers, cotton fibers, acryl fibers, silk fibers, polyethylene naphthalate (PEN), Aramid fibers (Aramid), and bamboo fibers.
An impregnation step S120, as shown in fig. 1 and 2, is to immerse the substrate 10 in an impregnation solution 20, so that the substrate 10 absorbs the impregnation solution 20 to form an impregnation solution layer 22 on the surface thereof. The impregnation solution 20 comprises a liquid resin; the liquid resin is selected from one or a combination of phenolic resin, epoxy resin and polyester resin. The impregnation solution 20 may further include 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 drying step S130, drying the substrate 10. In the drying step S130, a part of the moisture in the impregnation solution layer 22 on the substrate 10 is removed, so that the substrate 10 is solidified and hardened; the base material 10 absorbed with the liquid resin can have a certain hardness after it is solidified to provide a supporting force. Fig. 2 illustrates the drying step S130 by leaving the substrate 10 still for an air drying time; however, the present invention is not limited thereto, and the drying step S130 may be performed by dehydrating and drying with a drying device, not shown.
A forming step S140, performing hot press forming on the substrate 10 to form a wave portion 30. In the present embodiment, as shown in fig. 2, the substrate 10 is further heated, pressurized and molded by a hot pressing method through a hot pressing mold 200. The cross section of the molded substrate 10 is formed in a wavy shape.
An elastic disposing step S150 of disposing at least one elastic supporting portion 40 on at least one side surface of the wave portion 30 after the forming. The elastic setting step S150 sets the elastic support portion 40 in one manner selected from among spraying and pasting. The material of the elastic support portion 40 is selected from one or a combination of synthetic rubber and natural rubber; the shape of the ring is selected from one or the combination of rectangle, circle, fan, ring and trapezoid. In the present embodiment, as shown in fig. 2, the elastic support 40 is disposed on the wavy portion 30 of the substrate 10 by spraying, such that the elastic support 40 covers a portion of the pores of the substrate 10 and a portion of the impregnation solution layer 22. As shown in fig. 2 and 3, in the present embodiment, the elastic support portion 40 is integrally disposed on the surface of the wavy portion 30, such that the elastic support portion 40 completely covers the wavy portion 30 and forms a ring shape.
A cutting step S160, cutting the substrate 10 into at least one elastic wave 100 with a predetermined size. In the present embodiment, as shown in fig. 2, a cutting device 300 is further used to cut the substrate 10, so that the substrate 10 becomes the damper 100 with a specific shape and a predetermined size. In the present embodiment, as shown in fig. 2 and 3, the cutting step S160 is taken as an example to cut the damper into a circle; the cutting step S160 cuts the substrate at an outer position spaced apart from the wavy portion 30, so that the outer periphery of the cut damper 100 is spaced apart from the wavy portion 30 to form an outer peripheral portion 60 of the damper 100. However, the present invention is not limited thereto, and in the embodiment not shown in the figure, the cutting step S160 may also cut the substrate 10 into a rectangle or other shapes according to the actual structural configuration of the speaker; in addition, the cutting step S160 may also cut the substrate 10 at a position close to the outer periphery of the wavy portion 30, so that the outer periphery of the cut damper 100 is close to the wavy portion 30.
It should be noted that the cutting step S160 can be selected to simultaneously punch a hole in the center of the substrate 10. The cutting step S160 can optionally punch the substrate at an inner position spaced apart from the wavy portion 30, so that the cut elastic wave 100 has an inner periphery spaced apart from the wavy portion 30 to form an inner periphery 70 of the elastic wave 100, as shown in fig. 3; alternatively, the cutting step S160 can optionally perforate the substrate 10 at a position adjacent to the inner periphery of the wavy portion 30, so that the inner periphery of the cut damper 100 abuts against the wavy portion 30.
It should be noted that the cutting step S160 can be performed before or after the elastic setting step S150.
The elastic support 40 covers part of the pores of the substrate 10 and part of the impregnation solution layer 22, so that the elastic wave 100 is partially elastic and airtight by the elastic support 40.
For a further understanding of the nature of the invention, its nature of construction, use, and the manner of attaining it, reference should be made to the present invention as it is believed that the invention will be better understood and appreciated from a consideration of the following description:
please refer to fig. 1, fig. 2 and fig. 3, which are a block flow chart, a schematic flow chart and a perspective view of the elastic wave generated according to the first embodiment of the present invention. The present invention mainly utilizes the elastic material characteristics of the elastic support 40 to increase the elasticity and ductility of the area covered by the elastic support 40, so as to balance the situation that the elasticity of the elastic wave 100 is relatively poor because the impregnation solution layer 22 entirely covers the elastic wave 100. Meanwhile, the elastic support 40 is provided to cover the gaps between the fibers of the substrate 10, so that the area of the elastic wave 100 exposed from the solution layer 22 without the elastic support 40 is formed as a ventilation area relative to the area with the elastic support 40.
According to the damper according to the first embodiment, as shown in fig. 3, the elastic support portion 40 is disposed only on the wavy portion 30 of the damper 100, but not on the outer peripheral portion 60; thus, the region of the damper 100 where the elastic support portion 40 is provided (in the present embodiment, the entire wave portion 30) is provided with a local elasticity that is better but less air-permeable than the region where the elastic support portion 40 is not provided (in the present embodiment, the outer peripheral portion 60 and the inner peripheral portion 70). The region of the damper 100 where the elastic support portion 40 is not disposed (in the present embodiment, the outer peripheral portion 60 and the inner peripheral portion 70) is disposed with a lower local elasticity but a higher air permeability than the region where the elastic support portion 40 is disposed (in the present embodiment, the whole wave portion 30).
Therefore, when the loudspeaker is arranged on the loudspeaker and in an operating state, the invention utilizes the structural arrangement of the elastic supporting part 40, can improve the problem of poor overall elasticity of the wave part 30, effectively prevents the problems of noise generation, difficult appearance of low-frequency sound channels and poor load resilience, and has the effect of improving the output tone quality of the loudspeaker or the loudspeaker. Meanwhile, the present invention utilizes the manner of disposing the elastic support 40 at a specific position (i.e. the wave portion 30) to make the outer peripheral portion 60 and the inner peripheral portion 70 of the damper 100 keep air permeable, so as to facilitate the application thereof different from the wave portion 30; for example, the air permeable area has a lower elasticity but a higher hardness, which is beneficial to being matched and plugged in an external terminal.
In addition, in the forming step S140, the elastic support portion 40 is disposed on the wavy portion 30 of the damper 100 after the wavy portion 30 is formed on the damper 100 by hot pressing in the damper 100 according to the present invention. Therefore, the elastic support 40 of the present invention is not affected by the high temperature and high pressure of the molding step S140 to cause a change in physical properties, such as a change in shape or hardness.
In the present embodiment, as shown in fig. 2, in the elastic disposing step S150 after the forming step S140, the elastic supporting portion 40 is coated on the wavy portion 30 of the base material 10 in a spraying manner. The installation position, range and shape of the elastic support portion 40 can be freely determined by installing the elastic support portion 40 in a spraying manner. In addition, in other embodiments, the elastic disposing step S150 may directly attach the elastic supporting portion having a predetermined shape to the substrate 10 formed with the wave portion 30.
It should be noted that, by adjusting the components and concentration of the elastic support portion 40, the present invention can adjust the characteristics of the elastic support portion 40, and further adjust the local air permeability, hardness, elasticity, etc. of the damper 100.
Please refer to fig. 4, which is a perspective view of the damper 100 according to the second embodiment of the present invention. In this embodiment, compared with the first embodiment, in the elastic disposing step S150, the elastic supporting portion 40 is partially disposed on the surface of the wave portion 30, so that the elastic supporting portion 40 only partially covers the wave portion 30, and the area of the wave portion 30, where the elastic supporting portion 40 is not disposed and the impregnation solution layer 22 is exposed, is formed as a ventilation area 50. In addition, as shown in fig. 4, the present embodiment takes the wave part 30 provided with two elastic supporting parts 40, and the elastic supporting parts 40 take the shape of a sector as an example.
In the elastic disposing step S150, when there are a plurality of elastic supporting portions 40, the elastic supporting portions 40 may be disposed on one of the two side surfaces of the substrate 10 (as shown in fig. 4) or a combination thereof. Fig. 5 is an exploded perspective view of a damper according to a third embodiment of the present invention. In this embodiment, one of the elastic support portions 40 is disposed on one side surface of the base material 10, and the other of the elastic support portions 40 is disposed on the other side surface of the base material 10. However, the present invention is not limited thereto, and one or more than three elastic support portions 40 may be provided to the wavy portion 30.
It should be noted that in the second or third embodiment, in the elastic disposing step S150, the elastic supporting portions 40 are disposed in a radial direction of the damper 100 along a linear direction, that is, the elastic supporting portions 40 are disposed linearly in the radial direction of the damper 100. However, the present invention is not limited to this, and in the elastic installation step S150, the elastic support portions 40 may be installed along a plurality of linear directions, so that the elastic support portions 40 are linearly installed in two or more directions in the radial direction of the damper 100: the elastic support portions 40 may be arranged in a cross shape as shown in an external perspective view of the damper 100 according to the fourth embodiment of fig. 6, or in a cross shape not shown.
Further, in the elastic disposing step S150, when a plurality of the elastic supporting portions 40 are disposed, a plurality of the elastic supporting portions 40 are disposed at the wavy portion 30 in such a manner as to be spaced apart from each other in the circumferential direction or the radial direction.
Fig. 7 and 8 are perspective views showing the appearance of the damper 100 according to the fifth and sixth embodiments of the present invention, specifically illustrating the elastic support portions 40 spaced apart from each other in the circumferential direction and the elastic support portions 40 spaced apart from each other in the radial direction. In fig. 7, the elastic support portions 40 having a circular shape are taken as an example, and in the elastic disposing step S150, the elastic support portions 40 are disposed one by one along the circumferential direction such that the elastic support portions 40 are disposed at intervals from each other in the circumferential direction. Fig. 8 illustrates the elastic support portions 40 having a ring shape, and in the elastic disposing step S150, the elastic support portions 40 are disposed one by one in a concentric circle manner such that the elastic support portions 40 are disposed at intervals in a radial direction of the damper 100. Thus, the fifth and sixth embodiments can adjust the hardness, air permeability, and elasticity of the damper 100 in the circumferential direction or the radial direction.
The features of the invention and their expected effects are further set forth below:
the present invention relates to a method for manufacturing an elastic wave with an elastic support structure after molding, which mainly utilizes the structural arrangement of the elastic support portion 40 to improve the problems of too hard overall structure and poor elasticity of the elastic wave 100 caused by the arrangement of the impregnation solution layer 22, and meanwhile, the arrangement of the elastic support portion 40 can effectively prevent the problem of poor resilience to load, thereby having the effect of improving the output tone quality of a loudspeaker.
Therefore, the invention has the following implementation efficacy and technical efficacy:
first, the present invention can adjust the air permeability, hardness and elasticity of the specific position of the damper 100 by adjusting the composition, concentration and installation range of the elastic support 40, so that the damper 100 of the present invention can be a structure with adjustable local characteristics.
Secondly, when the voice coil vibrates, the elastic support part 40 provides the wave part 30 of the damper 100 with better elasticity and supporting force, so as to stably and durably control the amplitude of the damper 100. Therefore, the damper 100 of the present invention has a high fatigue resistance, prevents the damper 100 from being reduced in elasticity and embrittled in material due to long-term use, and has a long service life.
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 the present invention has been provided with the patent requirements and the application is made by the following appended method.
However, the foregoing is only one preferred embodiment of the invention. Features of the embodiments may be used in combination with each other instead of or in addition to each other, unless otherwise apparent. Furthermore, all structural changes that come within the meaning and range of equivalency of the specification and claims are to be embraced within their scope.
