Description

[Technical Field]

[0001] The present invention relates to a damper and a method for manufacturing the same, and more particularly to a damper having a wide, thin, and flat conductive structure and a method for manufacturing the same. [Background technology]

[0002] In a moving coil speaker, the conductive structure is responsible for transmitting AC power to the voice coil, and the damper is responsible for maintaining the voice coil in the precise position within the gap of the magnet core and ensuring that the voice coil moves back and forth in the axial direction when force is applied to the voice coil. The conductive structure is fixed to the damper body, which supports the conductive structure and improves its fatigue resistance, making it less likely to break.

[0003] The conductive structure can be fixed to the damper body by sewing threads. However, to sew the conductive structure to the surface of the damper body with sewing threads, manual operation of a sewing machine is required. Furthermore, the steps are quite complicated.

[0004] The conductive structure can be sandwiched between two main bodies. However, during the heat press molding process, the conductive structure may shift position and move away from the optimal position, which affects the resonance efficiency of the damper, voice coil, and diaphragm. Furthermore, the degree of misalignment of the conductive structure varies for each damper, which results in slightly different sound quality for each speaker. The steps are quite complicated.

[0005] Because the conductive structure is harder than the warp and weft threads and has poorer elasticity and toughness than the warp and weft threads, the area through which the conductive structure passes is harder than the rest of the damper body, and the elasticity and toughness of the area through which the conductive structure passes are poorer than the rest of the damper body, resulting in uneven hardness, elasticity, and toughness of the damper, which in turn results in uneven elastic recovery force and fatigue resistance of the damper, making the damper more susceptible to deformation and further affecting the output sound quality of the speaker.

[0006] Conventional conductive structures have a circular cross section, and circular conductive structures are generally made by twisting together multiple metal threads. Each metal thread has a portion located in the center, and this central portion is blocked by other metal threads, making it difficult for generated heat to be released and resulting in heat accumulation, making circular conductive structures prone to overheating.

[0007] Furthermore, since the circular conductive structure is relatively thick and protrudes significantly from the surface of the damper body, the circular conductive structure is easily crushed by the mold and may even be broken.

[0008] Furthermore, the ends of the twisted circular conductive structure are divergent, and are not easily bonded to the contact points of the connection terminals and the coils of the voice coil with adhesive.

[0009] Furthermore, the adhesive is prone to deterioration and may lose its viscosity, resulting in the ends of the circular conductive structure being prone to diverge and separate from the contact points of the connection terminals and the coils of the voice coil.

[0010] In addition, general metallic threads are made entirely of metal and are relatively expensive.

[0011] In addition, as long as the number of these metal threads is at least 20 or more, a circular conductive structure can be twisted together, and the manufacturing cost is relatively high. Summary of the Invention [Problem to be solved by the invention]

[0012] The main objective of the present invention is to provide a damper and a manufacturing method thereof having a wide, thin, and flat conductive structure, in which a weft thread is used to fix the multifilament thread body, completely eliminating the need for sewing threads.

[0013] Another object of the present invention is to provide a damper having a wide, thin, and flat conductive structure and a manufacturing method thereof, in which a multifilament yarn is fixed using a weft yarn, ensuring that the multifilament yarn does not shift during the hot press molding process and that the conductive structure is in an optimal position after cutting.

[0014] Another object of the present invention is to provide a damper having a wide, thin, and flat conductive structure and a manufacturing method thereof, in which the hardness, elasticity, and toughness of the area through which the conductive structure passes are adjusted using an elasticity adjustment area, making the area through which the conductive structure passes softer, more elastic, and more tough.

[0015] Yet another object of the present invention is to provide a damper having a wide, thin, and flat conductive structure, a manufacturing method thereof, and a conductive structure shape and a method for weaving metal threads, so that the metal threads are exposed to the outside without being blocked by other metal threads.

[0016] Another object of the present invention is to provide a damper and method of manufacturing the same having a conductive structure that is wide, thin, and flat in shape, with a relatively low risk of crush damage to the conductive structure.

[0017] Another object of the present invention is to provide a damper and a manufacturing method thereof having a wide, thin, and flat conductive structure, in which the soldering parts can prevent the ends of the conductive structure from spreading and can connect the ends of the conductive structure to the connection terminals and the voice coil.

[0018] Another object of the present invention is to provide a damper and a manufacturing method thereof having a wide, thin and flat conductive structure, and the metal thread structure can reduce costs and maintain constant conductivity.

[0019] Another object of the present invention is to provide a damper having a wide, thin, and flat conductive structure and a manufacturing method thereof, and to weave a multifilament yarn body using the minimum number of metal yarns. [Means for solving the problem]

[0020] In order to achieve the above object, the present invention provides a method for manufacturing a damper having a wide, thin, and flat conductive structure, the method comprising the steps of: forming metal threads by coating an outer surface of a core wire with a metal layer; intertwining a plurality of first intertwined portions of a plurality of metal threads with a plurality of second intertwined portions of the plurality of metal threads to weave a wide, thin, and flat multifilament yarn body, wherein both ends of each of the first intertwined portions are connected to second intertwined portions, the plurality of first intertwined portions are parallel to each other, the plurality of second intertwined portions are parallel to each other, and the plurality of first intertwined portions and the plurality of second intertwined portions extend in different directions; and placing a plurality of warp yarns at intervals from at least one multifilament yarn body, and weaving the multifilament yarn body. a step of entangling a plurality of weft yarns between the plurality of warp yarns and the at least one multifilament yarn to weave a substrate; a step of immersing the substrate in a resin solution; a step of drying the substrate; a step of heat-pressing a damper body onto the substrate while simultaneously heat-pressing at least two conductive structures that are wide, thin, and flat onto the at least one multifilament yarn; and a step of separating the body from the substrate while simultaneously separating the at least two conductive structures from the at least one multifilament yarn.

[0021] In some embodiments, the step of placing the plurality of warp yarns at a distance from the at least one multifilament yarn further includes making the distance between the at least one multifilament yarn and the warp yarns on both sides of it greater than the distance between the plurality of warp yarns; and the step of knitting the substrate further includes setting a first elastic adjustment region for the plurality of weft yarns from a first side of the at least one multifilament yarn to the warp yarn closest to the first side of the at least one multifilament yarn, and setting a second elastic adjustment region for the plurality of weft yarns from a second side of the at least one multifilament yarn to the warp yarn closest to the second side of the at least one multifilament yarn, and the width of the first elastic adjustment region is equal to the width of the second elastic adjustment region.

[0022] In some embodiments, after separating the body and the substrate, the method further comprises forming at least four solder portions by soldering opposite ends of the plurality of conductive structures.

[0023] In some embodiments, the core material is cotton.

[0024] In some embodiments, the number of metal threads is seven.

[0025] To achieve the above object, the present invention provides a damper having a wide, thin, and flat conductive structure, comprising a main body and at least two conductive structures. The main body is formed by intertwining a plurality of warp yarns and a plurality of weft yarns. The at least two conductive structures are wide, thin, and flat, are spaced apart from the warp yarns, extend linearly and parallel to each other, and are intertwined with the weft yarns. Each of the conductive structures is a wide, thin, and flat multifilament yarn, formed by intertwining a plurality of first intertwined portions of a plurality of metal yarns with a plurality of second intertwined portions of the plurality of metal yarns. Each of the metal yarns is formed by coating a metal layer on the outer surface of a core wire. A damper is provided in which both ends of each of the first intertwined portions are connected to a second intertwined portion, the plurality of first intertwined portions are parallel to each other, the plurality of second intertwined portions are parallel to each other, and the plurality of first intertwined portions extend in a different direction from the plurality of second intertwined portions.

[0026] In some embodiments, the distance between the at least one multifilament yarn and the warp yarns on either side thereof is greater than the distance between the plurality of warp yarns, and the region of the plurality of weft yarns from the first side of the at least one multifilament yarn to the warp yarn closest to the first side of the at least one multifilament yarn is set as a first elastic adjustment region, and the region of the at least one multifilament yarn from the second side of the at least one multifilament yarn to the warp yarn closest to the second side of the at least one multifilament yarn is set as a second elastic adjustment region.

[0027] In some embodiments, the damper further includes at least four solder portions formed by soldering on opposite ends of the conductive structures, respectively.

[0028] In some embodiments, the core material is cotton.

[0029] In some embodiments, the number of metal threads is seven. [Effects of the Invention]

[0030] The effect of the present invention is that the weft thread is used to fix the multifilament thread body, completely eliminating the need for sewing thread, reducing the manufacturing steps and lowering the manufacturing cost of the damper.

[0031] Furthermore, the weft yarn is used to fix the multifilament yarn, ensuring that the multifilament yarn does not shift during the hot press molding process, and ensuring that the conductive structure is in the optimal position after cutting.

[0032] Furthermore, by jointly adjusting the hardness, elasticity and toughness of the area through which the conductive structure passes through via the first elasticity adjusting area and the second elasticity adjusting area, the area through which the conductive structure passes becomes softer, more elastic and more tough, so that the hardness, elasticity and toughness of the area through which the conductive structure passes are equivalent to those of other areas of the main body.

[0033] In addition, the conductive structure has a wide, thin, and flat shape, and due to the way the metal threads are woven, the metal threads are exposed to the outside without being blocked by other metal threads, making it easier for generated heat to be dissipated and eliminating the problem of heat accumulation, so the conductive structure does not overheat.

[0034] Furthermore, the conductive structure is wide, thin and flat, and only slightly protrudes from the surface of the body, so there is a relatively low risk of it being crushed by the mold.

[0035] In addition, the soldering portion can prevent the end of the conductive structure from spreading, and can directly connect the end of the conductive structure to the contact point of the connection terminal and the coil of the voice coil.

[0036] Incidentally, the inner layer of each metal thread is a core wire, and the outer layer of each metal thread is a metal layer, which not only reduces costs but also maintains a constant conductivity.

[0037] Furthermore, based on the method of weaving the metal threads, only seven metal threads are required to weave the multifilament thread body, which can then be cut into two conductive structures, making the manufacturing cost relatively low. [Brief explanation of the drawings]

The present invention provides a method for manufacturing a damper having a wide, thin, and flat conductive structure, which includes the following steps:

[0041] In step S10, as shown in Figures 1 and 2, a metal layer 11 is coated on the outer surface of the core wire 12 to form a metal thread 10. More specifically, the material of the core wire 12 may not be conductive, is less expensive than a metal layer, and provides good support for the metal layer 11, such as cotton. The material of the metal layer 11 may be conductive, such as copper, aluminum, silver, or other metals or alloys.

[0042] 1, 3, and 4, step S20 involves weaving a wide, thin, and flat multifilament yarn body 20 by intertwining a plurality of first intertwined portions 13 of a plurality of metal yarns 10 with a plurality of second intertwined portions 14 of a plurality of metal yarns 10, with both ends of each first intertwined portion 13 connected to a second intertwined portion 14, these first intertwined portions 13 being parallel to each other, and these second intertwined portions 14 being parallel to each other, with the first intertwined portions 13 and the second intertwined portions 14 extending in different directions. Preferably, the number of metal yarns 10 is seven.

[0043] 1 and 5, step S30 involves placing a plurality of warp threads 30 on a loom (not shown) at a distance from two multifilament yarn bodies 20, and fixing these warp threads 30 and both ends of these multifilament yarn bodies 20 to the loom, so that these warp threads 30 extend linearly and are parallel to each other with respect to these multifilament yarn bodies 20. The distance D1 between each multifilament yarn body 20 and the warp threads 30 on either side thereof is greater than the distance D2 between these warp threads 30.

[0044] 1 and 6, in step S40, a loom is used to entangle a plurality of weft yarns 40 between the warp yarns 30 and the multifilament yarn bodies 20, thereby knitting the base material 50. Then, in these weft yarns 40, a region from the first side 21 of each multifilament yarn body 20 to the warp yarn 30 closest to the first side 21 of each multifilament yarn body 20 is set as a first elasticity adjustment region 61, and a region from the second side 22 of each multifilament yarn body 20 to the warp yarn 30 closest to the second side 22 of each multifilament yarn body 20 is set as a second elasticity adjustment region 62.

[0045] In step S50, as shown in Figures 1 and 7, the substrate 50 is immersed in a resin solution 71 in a resin tank 70, so that the resin is adsorbed onto and adheres to the multifilament yarn body 20, the warp yarns 30, and the weft yarns 40.

[0046] 1 and 8, in step S60, the temperatures of the first bake plate 81 and the second bake plate 82 are used to remove moisture and volatile substances from the resin on the substrate 50, thereby drying the substrate 50. Then, the resin is allowed to penetrate the substrate 50 and adhere to the multifilament yarn body 20, the warp yarns 30, and the weft yarns 40, thereby forming a solid resin layer (not shown).

[0047] In step S70, as shown in FIGS. 1 and 9, the substrate 50 is placed between the first mold 91 and the second mold 92, and the multifilament yarn 20 is aligned with the two grooves 911 of the first mold 91 and the two grooves 921 of the second mold 92. When the first mold 91 is clamped to the second mold 92, the pressing surface 912 of the first mold 91 and the molding surface 922 of the second mold 92 are jointly pressed against the substrate 50, and the plurality of wavy portions 21 of the body 210 of the damper 200 are pressed against the substrate 50. 1 (see FIG. 10 ) and a central hole pre-cut region 212 are formed, and each wavy portion 211 includes peaks 2111 and valleys 2112. The multifilament yarns 20 are positioned in the grooves 911 of the first mold 91 and the grooves 921 of the second mold 92, and the crimping surface 912, in cooperation with the shaping surface 922, presses the multifilament yarns 20 to form two wide, thin, and flat conductive structures 220 (see FIG. 10 ). A heating device (not shown) then heats the first mold 91 and the second mold 92 to 190 to 270°C, and the high temperature of the first mold 91 and the second mold 92 not only softens the resin and melts it into a liquid, but also allows the resin to fill in gaps and connect each part of the resin to form the final form of a solid resin layer that can coat the surfaces of the warp yarns 30, the weft yarns 40, and the conductive structures 220 of the main body 210.

[0048] In step S80, as shown in Figures 1 and 10, the first cutter 110 and the second cutter 120 jointly separate the main body 210 and the substrate 50, and at the same time, the first cutter 110 and the second cutter 120 jointly separate the conductive structures 220 and the multifilament yarn bodies 20.

[0049] In step S90, as shown in FIGS. 1 and 11, the bonding tool 130 solders both ends of these conductive structures 220 to form eight solder parts 230.

[0050] 12 is a perspective view of a damper 200 of the present invention. As shown in FIG. 12, referring to FIGS. 2 to 11, the present invention provides a damper 200 having a wide, thin, and flat conductive structure 220 including a body 210, four conductive structures 220, and eight solder portions 230.

[0051] As shown in FIG. 6, the main body 210 is formed by intertwining a plurality of warp threads 30 and a plurality of weft threads 40 .

[0052] As shown in Fig. 6, each conductive structure 220 is wide, thin, and flat, is spaced apart from the warp yarns 30, extends linearly and parallel to each other, and is intertwined with the weft yarns 40. Specifically, as shown in Figs. 3 and 4, each conductive structure 220 is a wide, thin, and flat multifilament yarn 20, which is formed by intertwining a plurality of first intertwined portions 13 of a plurality of metal yarns 10 with a plurality of second intertwined portions 14 of these metal yarns 10. As shown in Fig. 2, each metal yarn 10 is formed by covering the outer surface of a core wire 12 with a metal layer 11. As shown in Figures 3 and 4, both ends of each first entangled portion 13 are connected to second entangled portions 14, and these first entangled portions 13 are parallel to each other, and these second entangled portions 14 are parallel to each other, and these first entangled portions 13 and these second entangled portions 14 extend in different directions.

[0053] As shown in FIG. 12, these solder portions 230 are formed on both ends of these conductive structures 220 by soldering.

[0054] Fig. 13 is a perspective view of a speaker 300 of the present invention, Fig. 14 is an exploded view of the speaker 300 of the present invention, and Fig. 15 is a cross-sectional view of the speaker 300 of the present invention. As shown in Figs. 13, 14, and 15, the present invention provides a speaker 300 including a speaker body 310, a voice coil 320, and the damper 200. The speaker body 310 includes a base 311, a magnetic return device 312, an outer frame 313, a diaphragm 314, a dust cover 315, an edge 316, and a plurality of connection terminals 317. A magnetic return device 312 is mounted on a base 311, a voice coil 320 is mounted on the magnetic return device 312 and has a coil 321, an outer frame 313 is mounted on the magnetic return device 312, a diaphragm 314 is fitted around the voice coil 320, a dust cover 315 is mounted on the center hole of the diaphragm 314, an edge 316 is mounted between the upper edge of the diaphragm 314 and the outer frame 313, and connection terminals 317 are mounted on the outer frame 313 and have contact points. The damper 200 is fitted around the voice coil 320. Both ends of the conductive structures 220 are connected to the contact points of the connection terminals 317 and the coil 321 of the voice coil 320 by solder parts 230, respectively.

[0055] As can be seen, the method of the present invention utilizes these weft yarns 40 to secure these multifilament threads 20, completely eliminating the need for sewing threads, reducing manufacturing steps, and lowering the manufacturing costs of the damper 200.

[0056] Furthermore, the method of the present invention uses the weft yarns 40 to fix the multifilament threads 20, thereby firmly fixing the multifilament threads 20 in the optimal position. This ensures that the multifilament threads 20 do not shift during the hot press molding process. After the multifilament threads 20 are cut, the conductive structures 220 are ensured to be in the optimal position, further improving the resonance efficiency of the damper 200, voice coil 320, and diaphragm 314, and maintaining consistent sound quality for each speaker 300.

[0057] Furthermore, because the conductive structures 220 are harder than the warp threads 30 and the weft threads 40 and have poorer elasticity and toughness than the warp threads 30 and the weft threads 40, the areas through which the conductive structures 220 pass are harder than other areas of the body 210 and have poorer elasticity and toughness than other areas of the body 210. In the damper 200 of the present invention, the first elasticity adjusting area 61 and the second elasticity adjusting area 62 jointly adjust the hardness, elasticity and toughness of the areas through which the conductive structures 220 pass, so that the areas through which the conductive structures 220 pass are softer, more elastic and more tough, and therefore the hardness, elasticity and toughness of the areas through which the conductive structures 220 pass are equivalent to those of other areas of the body 210. As a result, the damper 200 has uniform hardness, elasticity, and toughness, uniform elastic recovery force and fatigue resistance, and is resistant to deformation and shattering, thereby improving the output sound quality of the speaker 300.

[0058] Furthermore, because the conductive structures 220 are wide, thin, and flat, and because of the way the metal threads 10 are woven, the top and bottom surfaces of the first intertwined portion 13 and the second intertwined portion 14 of each metal thread 10 are exposed to the outside and are not blocked by other metal threads 10, the generated heat can be easily dissipated, and there is no problem of heat accumulation, so the conductive structures 220 do not overheat.

[0059] Furthermore, the conductive structures 220 are wide, thin, and flat, and slightly protrude from the surface of the main body 210, reducing the risk of them being crushed by the first mold 91 and the second mold 92. To be on the safe side, the first mold 91 and the second mold 92 both form a plurality of grooves 911, 921, which protect the conductive structures 220 and ensure that they are not crushed by the first mold 91 and the second mold 92. Because the conductive structures 220 slightly protrude from the surface of the main body 210, there is no need to carve the grooves 911, 921 deeply, which reduces the manufacturing costs of the molds.

[0060] Furthermore, these solder parts 230 can not only prevent the ends of these conductive structures 220 from spreading, but also directly connect the ends of the conductive structures 220 to the contact points of the connection terminals 317 and the coil 321 of the voice coil 320. Even after long-term use, the fixing effect of these solder parts 230 remains unchanged, and the ends of these conductive structures 220 will not be separated from the contact points of the connection terminals 317 and the coil 321 of the voice coil 320.

[0061] Incidentally, the inner layer of each metal thread 10 is a core wire 12, and the outer layer of each metal thread 10 is a metal layer, which not only reduces costs but also maintains a constant conductivity.

[0062] Furthermore, based on the method of weaving these metal threads 10, the multifilament thread body 20 can be woven with only seven metal threads 10 (the minimum number) and cut into two conductive structures 220, so the manufacturing cost is relatively low.

[0063] The above description is intended to interpret the preferred embodiments of the present invention, and is not intended to limit the present invention in any way, so any modifications or changes made to the present invention within the same inventive spirit should be included in the intended scope of protection of the present invention.
