Description

Technical Field

[0001] The utility model relates to a speaker wire wave-damper fabric, in particular to a speaker wire wave-damper fabric with unequal width wave peaks to improve the shape of a central hole. 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 emitted 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 of the iron core of the magnet, ensuring that the voice coil reciprocates along the axis when subjected to force.

[0003] A conventional method for manufacturing a speaker wire damper includes the following steps: immersing a substrate in a resin solution; drying the substrate to form a resin solid layer on the substrate; placing the substrate between a pressing surface of a pressing mold and a molding surface of a molding mold, a pressing center portion of the pressing surface of the pressing mold and a molding center portion of the molding surface of the molding mold jointly heat-pressing a center hole of a speaker wire damper body on the substrate, a plurality of grooves of a pressing wave portion of the pressing surface of the pressing mold and a plurality of protrusions of a molding wave portion of the molding surface of the molding mold jointly heat-pressing a plurality of peaks and a plurality of troughs of a wave portion of the body on the substrate, a pressing outer portion of the pressing surface of the pressing mold and a molding outer portion of the molding surface of the molding mold jointly heat-pressing an outer portion of the body on the substrate to obtain a speaker wire damper fabric; and separating the speaker wire damper from the substrate.

[0004] Generally speaking, the pressed center and the formed center are both circular, all the grooves of the pressed wave are circular, and all the bumps of the formed wave are circular. Therefore, the ideal shape of the center hole is circular, so that the inner side of the center hole can be close to the voice coil, and the speaker wire elastic wave can keep the voice coil in the correct position in the gap of the magnet core to prevent the voice coil from shaking.

[0005] However, since the weft yarn has better stretching and elastic recovery than the warp yarn, after the speaker wire spring is separated from the base material, the circular center hole will shrink and become an ellipse, with the long axis of the center hole parallel to the warp yarn and the short axis of the center hole parallel to the weft yarn. The inside of the ellipse center hole cannot completely fit against the voice coil, and a gap will be generated between the inside of the ellipse center hole and the voice coil. The speaker wire spring cannot keep the voice coil in the correct position in the gap of the magnet core, causing the voice coil to shake. Utility Model Content

[0006] The main purpose of the utility model is to provide a speaker wire damper fabric with unequal width wave peaks to improve the shape of the center hole, and further to produce a speaker wire damper with a circular center hole.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a speaker wire damper fabric with unequal width peaks to improve the shape of the center hole, including a base material, a speaker wire damper, a plurality of wires and a resin solid layer. The base material is woven from a plurality of warp yarns and a plurality of weft yarns. The speaker wire damper is disposed on the base material and includes a body. The main body has a center hole, a wave portion and an outer portion, the center hole is elliptical, the major axis of the center hole is parallel to a first direction, the minor axis of the center hole is parallel to a second direction, the first direction is parallel to the warp yarns, and the second direction is parallel to the weft yarns. The wave portion includes multiple peaks and multiple troughs, the innermost peak of the wave portion is defined as a first side and a second side on two sides of the first direction and is respectively close to the two ends of the major axis of the center hole, the innermost peak of the wave portion is defined as a third side and a fourth side on two sides of the second direction and is respectively close to the two ends of the minor axis of the center hole, and the width of the first side and the second side of the innermost peak of the wave portion is smaller than the width of the third side and the fourth side of the innermost peak of the wave portion. The conductor assemblies are arranged on the substrate and pass through the body, the warp yarns and the conductor assemblies extend straight and parallel to each other, the weft yarns extend straight and perpendicular to the warp yarns and the conductor assemblies, each of the conductor assemblies is composed of a plurality of conductors, and each of the conductors is a monofilament. The resin solid layer covers the surfaces of the warp yarns, the weft yarns and the conductors.

[0008] In some embodiments, the conductive lines are spaced apart from each other.

[0009] In some embodiments, the wires are twisted so that each of the wires is combined to form a multifilament wire body with a circular cross-section.

[0010] In some embodiments, the wires are interlaced and woven with each other, so that each wire combination forms a multifilament wire body with a flat cross-section.

[0011] In some embodiments, the wire assemblies are woven into, sewn into, glued into, or clamped into the body.

[0012] The utility model has the effect that, since the extension ability and elastic recovery ability of the weft yarn are both better than those of the warp yarn, when the speaker wire damper fabric is hot-pressed, an elliptical center hole and a non-circular peak at the innermost side of the wave portion are produced. After the speaker wire damper is separated from the base material, the innermost peak of the wave portion shrinks into a circle, so that the center hole shrinks into a circle. Therefore, after the speaker is assembled, the inner side of the circular center hole can be completely close to the voice coil, so that the speaker wire damper produced can keep the voice coil in the correct position in the gap of the iron core of the magnet, and prevent the voice coil from shaking.

The pressing center portion 612 and the forming center portion 622 are both elliptical, so that the center hole 1101 is elliptical, the major axis 6121 of the pressing center portion 612, the major axis 6221 of the forming center portion 622 and the major axis 11011 of the center hole 1101 are all parallel to a first direction D1, the minor axis 6122 of the pressing center portion 612, the minor axis 6222 of the forming center portion 622 and the minor axis 11012 of the center hole 1101 are all parallel to a second direction D2, the first direction D1 is parallel to the warp yarns 11, and the second direction D2 is parallel to the weft yarns 12. The innermost groove 6131 of the pressing wave portion 613 is defined as a first side and a second side on two sides in the first direction D1 and is close to two ends of the long axis 6121 of the pressing center portion 612.

[0084] like Fig.10 and Fig.11 As shown, the utility model provides a speaker wire damper fabric 200 with unequal width wave peaks to improve the shape of the center hole, including a substrate 30, a speaker wire damper 100, a plurality of wire assemblies 20 and a resin solidifying layer 130.

[0085] Fig.12 It is a three-dimensional diagram of step S50 of the manufacturing method of the present invention. Fig.13 It is a three-dimensional diagram of a first embodiment of a speaker wire damper 100 of the present invention. Fig.14 yes Fig.13 After the speaker wire damper fabric 200 is manufactured, the following steps are further included: Step S50, such as Figure 1 , Fig.12 , Fig.13 and Fig.14 As shown, a cutting device 70 includes an upper cutter 71 and a lower cutter 72. The upper cutter 71 and the lower cutter 72 cut the speaker wire damper 100 from the substrate 30, so that the speaker wire damper 100 is separated from the substrate 30, and the innermost wave peak 11021 of the wave portion 1102 shrinks into a circle, so that the center hole 1101 shrinks into a circle.

[0086] Fig.15 It is a three-dimensional diagram of step S10 of the second embodiment of the manufacturing method of the present invention. Fig.16 It is a three-dimensional diagram of a second embodiment of a speaker wire damper 100A of the present invention. Fig.17yes Fig.16 Schematic diagram of area B. Fig.15 , Fig.16 and Fig.17 As shown, the difference between the second embodiment and the first embodiment is that: in step S10, the conductors 21 are twisted so that each conductor combination 20A forms a multifilament wire body with a circular cross section.

[0087] Fig.18 It is a three-dimensional diagram of step S10 of the third embodiment of the manufacturing method of the present invention. Fig.19 It is a three-dimensional diagram of a third embodiment of a speaker wire damper 100B of the present invention. Fig. 20 yes Fig.19 Schematic diagram of region C. Fig.18 , Fig.19 and Fig. 20 As shown, in terms of method, the difference between the third embodiment and the aforementioned embodiment is that: in step S10, the conductors 21 are interlaced and woven with each other so that each conductor assembly 20B forms a multifilament wire body with a flat cross section.

[0088] In summary, since the extension and elastic recovery capabilities of the weft yarn 12 are both better than those of the warp yarn 11, when the speaker wire damper fabric 200 is formed by hot pressing, the elliptical center hole 1101 and the innermost non-circular peak 11021 of the wave portion 1102 are produced. After the speaker wire damper 100 is separated from the substrate 30, the innermost peak 11021 of the wave portion 1102 will shrink into a circle, so that the center hole 1101 shrinks into a circle. Therefore, after the speaker is assembled, the inner side of the circular center hole 1101 can be completely close to the voice coil, so that the manufactured speaker wire dampers 100, 100A, 100B can keep the voice coil in the correct position in the gap of the iron core of the magnet to prevent the voice coil from shaking.

[0089] The above description is only used to explain the preferred embodiment of the utility model, and is not intended to limit the utility model in any form. Therefore, any modifications or changes made to the utility model under the same creative spirit should still be included in the scope of protection intended by the utility model.
