Abstract
Description
Technical Field
[0001] The present invention relates to a speaker wire damper and a manufacturing method thereof, and in particular to a speaker wire damper with multi-filament wires and a manufacturing method thereof. Background Art
[0002] Typical dynamic speakers produce sound by exploiting 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, likes repel). Specifically, the AC power generated by the power amplifier is transmitted to the voice coil via wires, changing the polarity of the magnetic field, causing the voice coil to generate a reaction force relative to the fixed magnetic field generated by the magnetic return device. Positive pulses cause the diaphragm to move outward relative to the magnet, while negative pulses cause it to move inward. When the voice coil pushes the diaphragm back and forth, the diaphragm pushes against the air, causing changes in air pressure to form sound waves. The elastic wave is responsible for maintaining the voice coil's correct position within the gap between the magnet core and the voice coil, ensuring that the voice coil reciprocates along its axis when subjected to force.
[0003] The conventional method for manufacturing a speaker wire damper is to use cotton cloth as a substrate, place multiple wires on the substrate, and then soak the substrate in resin, dry it, heat-press it, and cut it to obtain the speaker wire damper.
[0004] However, each conductor is typically made of a single twisted metal yarn or a braid of multiple metal yarns, resulting in a weak structural strength. During the thermoforming process, the conductors are easily damaged by the heat of the mold. Over extended use, this damage can become increasingly severe, and can even lead to breakage. Summary of the Invention

[0055] The following describes the embodiments of the present invention in more detail with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement the invention accordingly after studying the specification.
[0056] Figure 1 It is a flow chart of the manufacturing method of the present invention. Figure 2 1 is a schematic diagram of steps S10 to S30 of the first embodiment of the manufacturing method of the present invention. Figure 3 Schematic diagram of steps S40 to S70 of the first embodiment of the manufacturing method of the present invention. The present invention provides a method for manufacturing a speaker wire damper having a multi-wire conductor, comprising the following steps:
[0057] Step S10, as Figure 1 and Figure 2 As shown, two metal yarns 12 and 13 are twisted together to form a double-filament conductor 11 , and the materials of the metal yarns 12 and 13 are different or the same.
[0058] Step S20, as Figure 1 and Figure 2As shown, a plurality of double-filament conductors 11 are twisted together to form a multi-filament conductor 10 .
[0059] Step S30, as Figure 1 and Figure 2 As shown, a plurality of yarns 20 are woven into a base material 30, and a plurality of multifilament conductors 10 are disposed on the base material. Specifically, a plurality of warp yarns 21 of the yarns 20 and the multifilament conductors 10 extend in a straight line and are parallel to each other, and a plurality of weft yarns 22 of the yarns 20 extend in a straight line and are perpendicular to the warp yarns 21 and the multifilament conductors 10.
[0060] In the first embodiment, step S30 further includes: arranging the warp yarns 21 and the multifilament conductors 10 at intervals, the warp yarns 21 and the multifilament conductors 10 extending straight and parallel to each other; and interweaving the weft yarns 22 with the warp yarns 21 and the multifilament conductors 10 to weave the base material 30.
[0061] In some embodiments, step S30 further includes: sewing the multi-filament conductors 10 onto the substrate 30 using multiple stitches. In some embodiments, step S30 further includes: adhering the multi-filament conductors 10 to the substrate 30 using multiple adhesive layers. In some embodiments, step S30 further includes: sandwiching the multi-filament conductors 10 between two substrates 30.
[0062] Step S40, as Figure 1 and Figure 3 As shown, the substrate 30 is immersed in a resin solution 41 in a resin tank 40 , so that the warp yarns 21 , the weft yarns 22 and the multifilament conductors 10 absorb and adhere to the resin.
[0063] Step S50, as Figure 1 and Figure 3 As shown, a drying device 50 includes an upper baking plate 51 and a lower baking plate 52. The temperature of the upper baking plate 51 and the lower baking plate 52 is used to remove moisture and volatile substances in the resin on the substrate 30 to dry the substrate 30. At the same time, the resin penetrates into the substrate 30 and adheres to the warp yarns 21, the weft yarns 22 and the multi-filament conductors 10 to form a resin solid layer 130 (see Figure 5 ), the resin solid layer 130 covers the surfaces of the warp yarns 21, the weft yarns 22 and the multi-filament conductors 10.
[0064] Step S60, as Figure 1 and Figure 3As shown, a hot press molding apparatus 60 includes a molding die 61 and a heating device (not shown). The molding die 61 comprises an upper mold 611 and a lower mold 612. When the upper mold 611 and the lower mold 612 are closed and pressurized against the substrate 30, the heating device is energized to raise the temperature of the upper mold 611 and the lower mold 612 to 190°C to 270°C, thereby softening the resin on the substrate 30. This not only breaks up the resin but also fills the gaps, connecting them to form a final solid resin layer 130 that covers the warp yarns 21, the weft yarns 22, and the multi-filament conductors 10, thereby hot press-molding a speaker conductor damper 100 on the substrate 30.
[0065] Step S70, as Figure 1 and Figure 3 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 .
[0066] Figure 4 FIG. 1 is a perspective view of a first embodiment of a speaker wire damper 100 according to the present invention. Figure 5 yes Figure 4 Schematic diagram of area A. Figure 4 and Figure 5 As shown, the present invention provides a speaker wire damper 100 with a multi-filament conductor. The damper comprises a body 110, a plurality of multi-filament conductors 10, and a resin solidifying layer 130. The body 110 is woven from a plurality of yarns 20. Each multi-filament conductor 10 is formed by twisting a plurality of double-filament conductors 11. Each double-filament conductor 11 is formed by twisting two metal yarns 12 and 13. The metal yarns 12 and 13 may be made of different or identical materials. The resin solidifying layer 130 covers the surfaces of the yarns 20 and the multi-filament conductors 10.
[0067] Specifically, the yarns 20 include a plurality of warp yarns 21 and a plurality of weft yarns 22 . The warp yarns 21 and the multifilament conductors 10 extend straight and parallel to each other, and the weft yarns 22 extend straight and perpendicular to the warp yarns 21 and the multifilament conductors 10 .
[0068] In the first embodiment, the warp yarns 21 and the multifilament conductors 10 are spaced apart and extend straight and parallel to each other, and the weft yarns 22 are interwoven with the warp yarns 21 and the multifilament conductors 10 to weave the body 110 .
[0069] In some embodiments, the multi-filament wires 10 are sewn to the body 110 using multiple stitches. In some embodiments, the multi-filament wires 10 are adhered to the body 110 using multiple adhesive layers. In some embodiments, the multi-filament wires 10 are sandwiched between two pieces of the body 110.
[0070] Figure 6 FIG is a schematic diagram of steps S10 to S30 of the second embodiment of the manufacturing method of the present invention. Figure 6 As shown, the difference between the second embodiment and the first embodiment in terms of method is: step S20, braiding multiple double-filament wires 11 into a multi-filament wire 10A. Apart from this, the remaining technical features of the second embodiment are exactly the same as those of the first embodiment.

Figure 7 and Figure 8 As shown, in terms of structure, the second embodiment differs from the first embodiment in that each multi-filament conductor 10A is braided from a plurality of double-filament conductors 11 .
[0072] Figure 9 FIG is a schematic diagram of steps S10 to S30 of the third embodiment of the manufacturing method of the present invention. Figure 9 As shown, the method of the third embodiment differs from that of the first embodiment in that, in step S30, the warp yarns 21 extend straight and parallel to each other, and the weft yarns 22 extend straight and perpendicular to the warp yarns 21 along with the multifilament conductors 10. Specifically, step S30 further includes: arranging the warp yarns 21 at intervals and extending them straight; and arranging the weft yarns 22 and the multifilament conductors 10 at intervals and interweaving them with the warp yarns 21 to weave the base material 30.
[0073] Figure 10 FIG. 1 is a perspective view of a speaker wire damper 100B according to a third embodiment of the present invention. Figure 11 yes Figure 10 Schematic diagram of region C. Figure 10 and Figure 11 As shown, the third embodiment differs from the first embodiment in structure in that the warp yarns 21 extend straight and parallel to each other, and the weft yarns 22 extend straight and perpendicular to the multifilament conductors 10. Specifically, the warp yarns 21 are spaced apart and extend straight, while the weft yarns 22 are spaced apart and interwoven with the multifilament conductors 10 to weave the body 110.
[0074] Figure 12FIG is a schematic diagram of steps S10 to S30 of the fourth embodiment of the manufacturing method of the present invention. Figure 12 As shown, the fourth embodiment differs from the second embodiment in that the warp yarns 21 extend straight and parallel to each other, and the weft yarns 22 and the multifilament conductors 10A extend straight and perpendicular to the warp yarns 21. Specifically, step S30 further includes: arranging the warp yarns 21 at intervals and extending straight; and arranging the weft yarns 22 and the multifilament conductors 10A at intervals and interweaving them with the warp yarns 21 to weave the base material 30.
[0075] Figure 13 FIG. 1 is a perspective view of a speaker wire damper 100C according to a third embodiment of the present invention. Figure 14 yes Figure 13 Schematic diagram of area D. Figure 12 and Figure 14 As shown, the fourth embodiment differs from the second embodiment in structure in that the warp yarns 21 extend straight and parallel to each other, and the weft yarns 22 extend straight and perpendicular to the multifilament conductors 10. Specifically, the warp yarns 21 are spaced apart and extend straight, while the weft yarns 22 are spaced apart and interwoven with the multifilament conductors 10A to weave the body 110.
[0076] In summary, the multi-filament conductors 10, 10A are twisted or braided from multiple double-filament conductors 11, and have good structural strength. They are not easily damaged by the heat pressure of the forming mold 61, and the multi-filament conductors 10, 10A will not break even after long-term use.
[0077] Furthermore, the present invention can adjust the material of the metal yarns 12 and 13 according to different needs. The material of the metal yarns 12 and 13 can be copper, aluminum, silver, brass, copper alloy, etc., but the present invention is not limited thereto. Copper has good electrical conductivity and is relatively cheap. The electrical conductivity of aluminum is slightly worse than that of copper, but aluminum is lighter than copper. The electrical conductivity of silver is better than that of copper, but the price of silver is higher. Brass has better corrosion resistance. Copper alloys can obtain some special properties. In general, metal yarns 12 and 13 of the same material can provide the same electrical properties, and metal yarns 12 and 13 of different materials can provide some comprehensive properties, depending on the needs.
[0078] Furthermore, the multi-filament conductors 10, 10A can be laid on the loom simultaneously with the warp yarns 21, making the multi-filament conductors 10, 10A more taut and enhancing structural strength. The multi-filament conductors 10, 10A of the present invention can also be interwoven with the warp yarns 21 simultaneously with the weft yarns 22 on the loom, making the multi-filament conductors 10, 10A more ductile and preventing the joints at both ends of the multi-filament conductors 10, 10A from detaching from the voice coil.
[0079] 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.
