Abstract
Description
Technical Field
[0001] The utility model relates to a speaker wire spring, in particular to a speaker wire spring with multi-wire wires. 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 magnetic area 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 iron core of the magnet, ensuring that the voice coil reciprocates along the axis when subjected to force.
[0003] The existing method for manufacturing a speaker wire damper is to use cotton cloth as a substrate, arrange a plurality of wires on the substrate, and then the substrate is soaked in resin, dried, hot-pressed, cut, and other steps to obtain the speaker wire damper.
[0004] However, each wire is usually twisted with a single metal yarn or braided with multiple metal yarns, and the structural strength is poor. During the hot pressing step, the wire is easily damaged by the hot pressing of the molding die. After long-term use, the problem of wire damage will become more and more serious, and even the problem of wire breakage will occur. Utility Model Content

The resin solid layer covers the surface of the yarns and the multi-filament wires.
[0007] In some embodiments, the metal yarns are made of different or the same materials.
[0008] In some embodiments, the yarns include a plurality of warp yarns and a plurality of weft yarns, the warp yarns and the multifilament conductors extend straight and parallel to each other, and the weft yarns extend straight and perpendicular to the warp yarns and the multifilament conductors.

Figure 3 Schematic diagram of step S40 to step S70 of the first embodiment of the manufacturing method of the utility model. The utility model provides a manufacturing method of a speaker wire damper with a multi-wire wire, comprising the following steps:
[0052] 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.
[0053] Step S20, as Figure 1 and Figure 2 As shown, a plurality of double-filament conductors 11 are twisted into a multi-filament conductor 10 .
[0054] Step S30, as Figure 1 and Figure 2 As shown, a plurality of yarns 20 are woven into a substrate 30, and a plurality of multifilament conductors 10 are disposed on the substrate. Specifically, a plurality of warp yarns 21 of the yarns 20 and the multifilament conductors 10 extend straight and parallel to each other, and a plurality of weft yarns 22 of the yarns 20 extend straight and perpendicular to the warp yarns 21 and the multifilament conductors 10.
[0055] 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 substrate 30.
[0056] In some embodiments, step S30 further includes: the multi-filament wires 10 are sewn on the substrate 30 through multiple stitches. In some embodiments, step S30 further includes: the multi-filament wires 10 are adhered to the substrate 30 through multiple adhesive layers. In some embodiments, step S30 further includes: the multi-filament wires 10 are sandwiched between two substrates 30.
[0057] Step S40, as Figure 1 and Figure 3As 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 multi-filament conductors 10 absorb and adhere to the resin.

In addition to breaking the resin, the resin also fills the gaps and connects to form the final shape of the resin solid layer 130, so as to cover between the warp yarns 21, the weft yarns 22 and the multi-filament wires 10, thereby hot pressing a speaker wire damper 100 on the substrate 30.
[0060] 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 .

Even if used for a long time, the multi-filament conductors 10, 10A will not break.
[0072] Furthermore, the utility model 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 alloys, etc., but the utility model 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.
[0073] In addition, the multi-filament conductors 10, 10A can be arranged on the loom synchronously with the warp yarns 21, so that the multi-filament conductors 10, 10A are more taut and have better structural strength. The multi-filament conductors 10, 10A of the utility model can also be interwoven with the warp yarns 21 through the loom synchronously with the weft yarns 22, so that the multi-filament conductors 10, 10A are more ductile, and the joints at both ends of the multi-filament conductors 10, 10A are not easy to separate from the voice coil.
[0074] 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 spirit of the utility model should still be included in the scope of protection intended by the utility model.
