Abstract
Description
Technical Field
[0001] The present invention relates to a speaker and a manufacturing method thereof, and in particular to a speaker with a wire spring wave capable of locally adjusting elasticity and a manufacturing method thereof. Background Art
[0002] A general dynamic speaker produces sound by using the principle that the reaction force of a fixed magnetic field causes another magnetic field to move in the opposite direction (i.e., opposites attract and likes repel). Specifically, the power alternating current generated by the power amplifier is transmitted to the voice coil through a wire to change the polarity of the magnetic field, causing the voice coil to produce a reaction force relative to the fixed sector generated by the magnetic return device. Positive pulses cause the diaphragm to move outward relative to the magnet, and negative pulses cause the diaphragm to move inward. When the voice coil pushes the diaphragm to reciprocate, the diaphragm pushes the air, and the air pressure changes to form sound waves. The elastic wave is responsible for keeping the voice coil in the correct position in the gap between the magnet core and ensuring that the voice coil reciprocates along the axis when subjected to force.
[0003] However, in existing speakers, the wire is suspended in the air without any support, so the wire alone bears the vibration force transmitted by the voice coil, so that after the voice coil moves rapidly and frequently for a period of time, the wire is easily fatigued and broken.
[0004] In order to solve the above problems, the industry began to develop a method to fix the wire on the damper during the damper manufacturing process. First, the base material is immersed in liquid synthetic resin to allow the base material to absorb the synthetic resin; then, the base material that absorbs the synthetic resin is dried and hardened; then, the wire is bonded to the surface of the base material; then, the base material and the wire are hot-pressed by a hot-pressing molding device to form a wire damper; finally, a cutting device cuts the wire damper off the base material. The wire is supported by the body of the wire damper, which improves the fatigue resistance of the wire and makes it less likely to break.
[0005] The wire is glued to the wire setting area of the body of the wire damper. When the hot press forming device hot presses the wire damper on the substrate, the wire cannot push the warp yarns on both sides of the wire setting area outward, so that the wire protrudes from the surface of the body of the wire damper, causing the wire to be easily damaged by the hot press of the hot press forming device. The wire damper cannot be used due to the damage of the wire and must be scrapped, which is quite wasteful. It can be seen that the yield rate of the wire damper made by the existing manufacturing method is low and the manufacturing cost is high.
[0006] Furthermore, because the wire is harder than the body of the wire damper, and the elasticity and toughness of the wire are worse than the elasticity and toughness of the body of the wire damper, the wire cannot stretch the warp yarns on both sides of the wire setting area outward, and the combination of the wire setting area and the wire is harder than other areas of the body of the wire damper, and the elasticity and toughness of the combination of the wire setting area and the wire are worse than other areas of the body of the wire damper. Therefore, the hardness, elasticity and toughness of the wire damper are uneven, resulting in uneven elastic recovery force and fatigue resistance of the wire damper, making the wire damper easily deformed, thereby affecting the sound quality of the speaker output.
[0007] In addition, the hot press forming device requires a larger pressing force to form the peaks and troughs of the wave structure on the substrate, and a smaller pressing force to form the inner wall on the substrate. It can be seen that the pressing force of the hot press forming device is uneven, so the hot press forming device applies uneven force to the wire, causing the following two problems: First, the wire is easily deformed due to uneven force; second, the deformed wire will cause the overall structure of the wire elastic wave to be unbalanced. The above two problems will affect the sound quality of the speaker output. Summary of the invention
[0008] The main purpose of the present invention is to provide a speaker with a wire damper with locally adjustable elasticity and a manufacturing method thereof, so as to ensure that the wire is not damaged by the heat pressing of a hot pressing forming device, and the yield rate of the manufactured wire damper is high and the manufacturing cost is low.

Preferably, as Figure 8 and Fig. 9 As shown, the depth D1 of at least one hollow portion 414 at the wave crest 4111 is equal to the depth D2 of at least one hollow portion 414 at the wave trough 4112; Fig.10 As shown, the depth D31 of at least one hollow portion 414 in the inner side wall 4113 is equal to the depth D32 of at least one hollow portion 414 in the outer side wall 4114. In the first embodiment, the wire damper 40 includes four wires 42, the body 41 includes four wire arrangement areas 413, the wires 42 are respectively arranged on the wire arrangement areas 413; the wire arrangement areas 413 are concave to form four hollow portions 414; the wires 42 extend in the hollow portions 414 respectively.
[0060] Cutting step S6: Figure 2 As shown, a cutting device 60 includes an upper cutter 61 and a lower cutter 62 . The upper cutter 61 and the lower cutter 62 cut the wire damper 40 from the substrate 10 , so that the wire damper 40 is separated from the substrate 10 .
[0061] Assembly step S7: Figures 2 to 5 As shown, the speaker body 71 includes a base 711, a magnetic return device 712, an outer frame 713, a diaphragm 714, a dust cover 715 and a suspension 716. The magnetic return device 712 is disposed on the base 711, a voice coil 72 is movably disposed in the magnetic return device 712, the outer frame 713 is disposed on the outer side of the magnetic return device 712 and supports the outer side of the body 41 of the wire damper 40, the diaphragm 714 is sleeved on the voice coil 72, the dust cover 715 is disposed on a central hole of the diaphragm 714, and the suspension 716 is disposed between the top edge of the diaphragm 714 and the outer frame 713. The central hole 412 of the wire damper 40 is sleeved on the voice coil 72, and the wire 42 of the wire damper 40 is connected to the voice coil 72. Therefore, the speaker body 71, the voice coil 72 and the wire damper 40 are assembled together to form a speaker 70.
[0062] like Figures 3 to 10 As shown, the present invention provides a speaker 70 with a wire damper with locally adjustable elasticity, including a speaker body 71, a voice coil 72 and a wire damper 40. The structures and connection relationship of the speaker body 71, the voice coil 72 and the wire damper 40 are as described above.
[0063] Therefore, because the wire 42 is not adhered to the surfaces of the yarns of the substrate 10 when it is disposed on the substrate 10, when the hot press molding device 50 hot press molds the wire damper 40 on the substrate 10, the wire disposing area 413 can be pressed by the wire 42 to be concave to form the hollow portion 414, thereby ensuring that the wire 42 will not be damaged by the hot press of the hot press molding device 50. The resulting wire damper 40 has a higher yield and a lower manufacturing cost.
[0064] Furthermore, because the first elastic adjustment area 151 and the second elastic adjustment areas 152 can adjust the hardness, elasticity and toughness of the wire setting area 413, the wire setting area 413 becomes softer and the elasticity and toughness are improved, so that the hardness, elasticity and toughness of the combination of the wire setting area 413 and the wire 42 are equivalent to the hardness, elasticity and toughness of other areas of the body 41. Therefore, the wire damper 40 has uniform hardness, elasticity and toughness, and thus has uniform elastic restoring force and fatigue resistance, is not easy to deform and crack, and improves the sound quality of the speaker output.
[0065] In addition, the hot pressing forming device 50 must apply an even force to each conductor 42 to ensure that each conductor 42 will not be deformed due to uneven force. However, the hot pressing forming device 50 requires a larger pressing force to hot press form the wave crest 4111 and the wave trough 4112, and the hot pressing forming device 50 requires a smaller pressing force to hot press form the inner wall 4113 and the outer wall 4114. Therefore, the depth D31 of the hollow portion 414 at the inner side wall 4113 is less than the depth D1 of the hollow portion 414 at the wave crest 4111, the depth D32 of the hollow portion 414 at the outer side wall 4114 is less than the depth D1 of the hollow portion 414 at the wave crest 4111, the depth D31 of the inner side wall 4113 of the hollow portion 414 is less than the depth D2 of the hollow portion 414 at the wave trough 4112, and the depth D32 of the outer side wall 4114 of the hollow portion 414 is less than the depth D2 of the hollow portion 414 at the wave trough 4112. In other words, the depth of the hollow portion 414 is asymmetric. Since the hollow portion 414 with asymmetric depth can provide the wire 42 to extend therein in an asymmetric distribution, the hot pressing forming device 50 can apply force evenly to each wire 42, so that the wire 42 can maintain its original shape and will not deform, thereby improving the sound quality output by the speaker. While the conductor 42 maintains its original shape, a larger volume of the conductor 42 is located in the hollow portion 414 at the wave crest 4111 and the wave trough 4112, a smaller volume of the conductor 42 is located in the hollow portion 414 at the inner wall 4113 and the outer wall 4114, a smaller volume of the conductor 42 is exposed on the surface of the main body 41 at the wave crest 4111 and the wave trough 4112, and a larger volume of the conductor 42 is exposed on the surface of the main body 41 at the inner wall 4113 and the outer wall 4114.
[0066] Furthermore, the depth D1 of the hollow portion 414 at the crest 4111 is equal to the depth D2 of the hollow portion 414 at the trough 4112, so that the volume of the conductive wire 42 at the crest 4111 and the trough 4112 in the hollow portion 414 is consistent, and the volume of the conductive wire 42 exposed on the surface of the body 41 at the crest 4111 and the trough 4112 is consistent. Furthermore, the depth D31 of the hollow portion 414 at the inner sidewall 4113 is equal to the depth D32 of the hollow portion 414 at the outer sidewall 4114, so that the volume of the conductive wire 42 at the inner sidewall 4113 and the outer sidewalls 4114 in the hollow portion 414 is consistent, and the volume of the conductive wire 42 exposed on the surface of the body 41 at the inner sidewall 4113 and the outer sidewall 4114 is consistent. Therefore, the overall structure of the wire damper 40 is relatively balanced, with uniform hardness, elasticity and toughness, and thus has uniform elastic recovery force and fatigue resistance, is not easily deformed and cracked, and improves the sound quality of the speaker output.

The first sheet 415 is combined with the second sheet 416, and at least one first wire setting area 413A corresponds to at least one second wire setting area 413B. At least one first wire arrangement region 413A is concave to form at least one first groove 4141 and at least one second wire arrangement region 413B is concave to form at least one second groove 4142. The at least one first groove 4141 and the at least one second groove 4142 together form at least one hollow portion 414A. At least one wire 42 extends in the at least one hollow portion 414A and its two ends respectively penetrate the inner side and the outer side of the first sheet 415 and the second sheet 416.

The widths of the first lower elastic adjustment area 171 and the second lower elastic adjustment area 172 are equal, and the distances between the remaining second warp yarns 11B are smaller than the widths of the first lower elastic adjustment area 171 and the second lower elastic adjustment area 172. Figures 14 to 16 As shown, the depth D4 of at least one first groove 4141 at the first wave crest 4111A is less than the depth D5 of at least one second groove 4142 at the second wave crest 4111B, the depth D6 of at least one first groove 4141 at the first wave valley 4112A is greater than the depth D7 of at least one second groove 4142 at the second wave valley 4112B, the depth D81 of at least one first groove 4141 at the first inner sidewall 4113A is equal to the depth D91 of at least one second groove 4142 at the second inner sidewall 4113B, and the depth D82 of at least one first groove 4141 at the first outer sidewall 4114A is equal to the depth of at least one second groove 4142 at the second outer sidewall 4114B. Preferably, as Fig.14 and Fig.15 As shown, the depth D4 of at least one first groove 4141 at the first wave crest 4111A is equal to the depth D7 of at least one second groove 4142 at the second wave valley 4112B, and the depth D5 of at least one second groove 4142 at the second wave crest 4111B is equal to the depth D6 of at least one first groove 4141 at the first wave valley 4112A; Fig.16As shown, the depth D81 of at least one first groove 4141 in the first inner wall 4113A is equal to the depth D82 of at least one first groove 4141 in the first outer wall 4114A, and the depth D91 of at least one second groove 4142 in the second inner wall 4113B is equal to the depth D92 of at least one second groove 4142 in the second outer wall 4114B. In the second embodiment, the wire damper 40A includes four wires 42, the first sheet 415 includes four first wire setting areas 413A, the second sheet 416 includes four second wire setting areas 413B, the wires 42 are respectively set on the first wire setting areas 413A and the second wire setting areas 413B; the first wire setting areas 413A are concave to form four first grooves 4141, the second wire setting areas 413B are concave to form four second grooves 4142, the first grooves 4141 and the second grooves 4142 together form four hollow portions 414A; the wires 42 extend into the hollow portions 414A respectively.
[0073] Assembly step S7: Fig. 11B As shown, the first center hole 412A and the second center hole 412B are jointly sleeved on the voice coil.
[0074] like Figures 12 to 16 As shown, the present invention provides a speaker 70A with a wire damper with locally adjustable elasticity. The difference between the structure of the speaker 70A of the second embodiment and the structure of the speaker 70 of the first embodiment is as described above.
[0075] Therefore, because the wire 42 is not adhered to the surfaces of the yarns of the first cloth body 101 when it is set on the first cloth body 101, when the hot press molding device 50 hot press molds the wire damper 40A on the substrate 10A, the first wire setting area 413A and the second wire setting area 413B can be pressed by the wire 42 to form the first groove 4141 and the second groove 4142. The first groove 4141 and the second groove 4142 can further form the hollow portion 414A, ensuring that the wire 42 will not be damaged by the hot press of the hot press molding device 50. The yield rate of the manufactured wire damper 40A is higher and the manufacturing cost is low.
[0076] Furthermore, because the first upper elastic adjustment area 161 and the second upper elastic adjustment area 162 can adjust the hardness, elasticity and toughness of the first wire setting area 413A, and the first lower elastic adjustment area 171 and the second lower elastic adjustment area 172 can adjust the hardness, elasticity and toughness of the second wire setting area 413B, the first wire setting area 413A and the second wire setting area 413B become softer and the elasticity and toughness are improved, so that the hardness, elasticity and toughness of the combination of the first wire setting area 413A, the second wire setting area 413B and the wire 42 are equivalent to the hardness, elasticity and toughness of other areas of the body 41A. Therefore, the wire damper 40A has uniform hardness, elasticity and toughness, and thus has uniform elastic recovery force and fatigue resistance, is not easy to deform and crack, and improves the sound quality of the speaker output.
[0077] In addition, the hot pressing forming device 50 must apply an even force to each conductor 42 to ensure that each conductor 42 will not be deformed due to uneven force. However, the hot pressing forming device 50 needs a larger pressing force to hot press form the first wave peak 4111A, the first wave valley 4112A, the second wave peak 4111B and the second wave valley 4112B. The hot pressing forming device 50 needs a smaller pressing force to hot press form the first inner wall 4113A, the first outer wall 4114A, the second inner wall 4113B and the second outer wall 4114B. Therefore, the depth D4 of the first groove 4141 at the first wave crest 4111A is less than the depth D5 of the second groove 4142 at the second wave crest 4111B, the depth D6 of the first groove 4141 at the first wave valley 4112A is greater than or equal to the depth D7 of the second groove 4142 at the second wave valley 4112B, the depth D81 of the first groove 4141 at the first inner sidewall 4113A is equal to the depth D91 of the second groove 4142 at the second inner sidewall 4113B, and the depth D82 of the first groove 4141 at the first outer sidewall 4114A is equal to the depth of the second groove 4142 at the second outer sidewall 4114B. In other words, the depth of the hollow portion 414A is asymmetric. The hollow portion 414A with asymmetric depth can provide the wire 42 to extend therein in an asymmetric distribution, so the hot pressing forming device 50 can apply force to each wire 42 evenly, so that the wire 42 can maintain its original shape and will not deform, thereby improving the sound quality of the speaker output. When the wire 42 maintains its original shape, the diameter of the hollow portion 414A between the first crest 4111A and the second crest 4111B is equal to the diameter of the wire 42, the diameter of the hollow portion 414A between the first trough 4112A and the second trough 4112B is equal to the diameter of the wire 42, the diameter of the hollow portion 414A between the first inner side wall 4113A and the second inner side wall 4113B is equal to the diameter of the wire 42, and the diameter of the hollow portion 414A between the first outer side wall 4114A and the second outer side wall 4114B is equal to the diameter of the wire 42.
[0078] Furthermore, the depth D4 of the first groove 4141 at the first wave peak 4111A is equal to the depth D7 of the second groove 4142 at the second wave valley 4112B, and the depth D5 of the second groove 4142 at the second wave peak 4111B is equal to the depth D6 of the first groove 4141 at the first wave valley 4112A, so that the diameter of the space between the hollow portion 414A at the first wave peak 4111A and the second wave peak 4111B is equal to the diameter of the space between the hollow portion 414A at the second wave valley 4112B and the second wave valley 4112B. Furthermore, the depth D81 of the first groove 4141 in the first inner sidewall 4113A is equal to the depth D82 of the first groove 4141 in the first outer sidewall 4114A, and the depth D91 of the second groove 4142 in the second inner sidewall 4113B is equal to the depth D92 of the second groove 4142 in the second outer sidewall 4114B, so that the diameter of the space between the first inner sidewall 4113A and the first outer sidewall 4114A of the hollow portion 414A is equal to the hollow portion 414A, and the diameter of the space between the second inner sidewall 4113B and the second outer sidewall 4114B of the hollow portion 414A is equal to the hollow portion 414A. Therefore, the overall structure of the wire damper 40A is relatively balanced, with uniform hardness, elasticity and toughness, and thus has uniform elastic recovery force and fatigue resistance, is not easy to deform and crack, and improves the sound quality of the speaker output.
[0079] Importantly, since the wire 42 is clamped by the first cloth body 101 and the second cloth body 102, it will not contact the thermoforming device 50, ensuring that the wire 42 will not be damaged by the heat pressing of the thermoforming device 50. The resulting wire damper 40A has a higher yield and a lower manufacturing cost.
[0080] The above description is only used to explain the preferred embodiments of the present invention, and is not intended to limit the present invention in any form. Therefore, any modifications or changes made to the present invention under the same inventive spirit should still be included in the scope of protection intended by the present invention.
