Description

Technical Field

[0001] The present invention relates to a speaker wire damper fabric and a manufacturing method thereof, and in particular to a speaker wire damper fabric with unequal width wave peaks to improve the shape of a center hole 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 sector 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's core and the iron core, ensuring that the voice coil reciprocates along its 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 solid resin layer on the substrate; placing the substrate between a pressing surface of a pressing mold and a molding surface of a molding mold; hot-pressing 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 to form a center hole of the speaker wire damper body on the substrate; hot-pressing 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 to form a plurality of peaks and troughs of a wave portion of the body on the substrate; hot-pressing an outer pressing portion of the pressing surface of the pressing mold and a molding outer portion of the molding surface of the molding mold to form an outer portion of the body on the substrate, thereby obtaining a speaker wire damper fabric; and separating the speaker wire damper from the substrate.

[0004] Generally speaking, the press-fit center and the molded center are both circular, all grooves in the press-fit wave section are circular, and all bumps in the molded wave section are circular. Therefore, the ideal shape for the center hole is a circle. This allows the inner side of the center hole to rest closely against the voice coil, allowing the speaker wire damper to hold the voice coil in place within the gap between the magnet and the core, preventing it from wobbling.

[0005] However, because the weft yarn has greater stretchability and elastic recovery than the warp yarn, after the speaker wire damper separates from the base material, the circular center hole shrinks and becomes elliptical, with the long axis of the center hole parallel to the warp yarn and the short axis parallel to the weft yarn. The inside of the elliptical center hole cannot completely align with the voice coil, creating a gap between the inner side of the elliptical center hole and the voice coil. The speaker wire damper cannot hold the voice coil in the correct position within the gap between the magnet cores, causing the voice coil to wobble. Summary of the Invention

[0006] The main purpose of the present invention is to provide a speaker wire damper fabric with unequal width wave peaks to improve the shape of the center hole and a manufacturing method thereof.

[0011] In some embodiments, the step of weaving the substrate further comprises: the conductive wire assemblies are woven into, sewn into, bonded into, or sandwiched into the substrate.

[0012] To achieve the aforementioned objectives, the present invention provides a speaker wire damper fabric with unequal-width wave crests to improve the shape of a central hole. The fabric comprises a base material, a speaker wire damper, a plurality of wires, and a resin-solidified 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 main body. The main body has a center hole, a wave portion and an outer portion, the center hole is elliptical, the long axis of the center hole is parallel to a first direction, the short 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.

[0016] In some embodiments, the wire assemblies are woven into, sewn into, bonded into, or clamped into the body.

[0017] The present invention's effectiveness lies in the fact that, because the weft yarn has superior stretchability and elastic recovery compared to the warp yarn, when hot-pressing the speaker wire damper fabric, an elliptical center hole and a non-circular innermost crest of the wavy portion are formed. After the speaker wire damper is separated from the base material, the innermost crest of the wavy portion shrinks into a circular shape, causing the center hole to shrink into a circular shape. As a result, after the speaker is assembled, the inner side of the circular center hole rests firmly against the voice coil, allowing the resulting speaker wire damper to securely hold the voice coil in place within the gap between the magnet core and prevent wobble.

Figure 11 This is a cross-sectional view of a speaker wire damper fabric 200 of the present invention. The present invention provides a method for manufacturing a speaker wire damper fabric with unequal width peaks to improve the shape of the center hole, comprising the following steps:

[0085] Step S10, as Figure 1 and Figure 2 As shown, a plurality of warp yarns 11 and a plurality of weft yarns 12 are woven into a base material 30, and a plurality of conductive wire assemblies 20 are disposed on the base material 30. The warp yarns 11 and the conductive wire assemblies 20 extend straight and parallel to each other, and the weft yarns 12 extend straight and perpendicular to the warp yarns 11 and the conductive wire assemblies 20. Each conductive wire assembly 20 is composed of a plurality of conductive wires 21, each conductive wire 21 being a monofilament, and the conductive wires 21 are spaced apart from each other.

[0086] In the first embodiment, step S10 further includes: arranging the warp yarns 11 and the conductive wire assemblies 20 at intervals; and interweaving the weft yarns 12 with the warp yarns 11 and the conductive wire assemblies 20 to weave a base material 30. In some embodiments, step S10 further includes: sewing the conductive wire assemblies 20 onto the base material 30 using multiple stitches. In some embodiments, step S10 further includes: adhering the conductive wire assemblies 20 to the base material 30 using multiple adhesive layers. In some embodiments, step S10 further includes: sandwiching the conductive wire assemblies 20 between two sheets of base material 30.

[0087] Step S20, 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 11 , the weft yarns 12 and the conductive wires 21 absorb and adhere to the resin.

[0088] Step S30, as Figure 1 and Figure 4 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 11, the weft yarns 12 and the conductive wires 21 to form a resin solid layer 130 (see Figure 14 ), the resin solid layer 130 covers the surfaces of the warp yarns 11, the weft yarns 12 and the conductive wires 21 (see Figure 14 ).

[0089] Step S40, as Figure 1 and Figures 5 to 11As shown, the substrate 30 is placed between a pressing surface 611 of a pressing mold 61 and a molding surface 621 of a molding mold 62; a pressing center portion 612 of the pressing surface 611 of the pressing mold 61 and a molding center portion 622 of the molding surface 621 of the molding mold 62 jointly heat press-form a center hole 1101 of a body 110 of a speaker wire damper 100 on the substrate 30; a plurality of grooves 6131 of a pressing wave portion 613 of the pressing surface 611 of the pressing mold 61 and a plurality of grooves 6131 of the molding mold 62 The plurality of protrusions 6231 of a wavy portion 623 of the molding surface 621 of the molding die 62 are jointly hot-pressed on the substrate 30 to form the plurality of wave crests 11021 and the plurality of wave troughs 11022 of a wavy portion 1102 of the main body 110. Furthermore, a pressing outer portion 614 of the pressing surface 611 of the pressing mold 61 and a molding outer portion 624 of the molding surface 621 of the molding mold 62 are jointly hot-pressed on the substrate 30 to form the outer portion 1103 of the main body 110, thereby obtaining a speaker wire damper fabric 200. The pressing center portion 612 and the forming center portion 622 are both elliptical, so that the center hole 1101 is elliptical, and 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, and 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 press-fitting wave portion 613 is defined as a first side and a second side on both sides in the first direction D1, and is respectively close to the two ends of the long axis 6121 of the press-fitting core portion 612. The innermost groove 6131 of the press-fitting wave portion 613 is defined as a third side and a fourth side on both sides in the second direction D2, and is respectively close to the two ends of the short axis 6122 of the press-fitting core portion 612. The innermost protrusion 6231 of the molding wave portion 623 is defined as a first side and a second side on both sides in the first direction D1, and is respectively close to the two ends of the long axis 6221 of the molding core portion 622. The innermost protrusion 6231 of the molding wave portion 623 is defined as a third side and a fourth side on both sides in the second direction D2, and is respectively close to the two ends of the short axis 6222 of the molding core portion 622.The width W1 of the first and second sides of the innermost groove 6131 of the pressed wave portion 613 is equal to the width W2 of the first and second sides of the innermost protrusion 6231 of the molded wave portion 623, the width W3 of the third and fourth sides of the innermost groove 6131 of the pressed wave portion 613 is equal to the width W4 of the third and fourth sides of the innermost protrusion 6231 of the molded wave portion 623, the width W1 of the first and second sides of the innermost groove 6131 of the pressed wave portion 613 and the width W2 of the first and second sides of the innermost protrusion 6231 of the molded wave portion 623 are smaller than the width W3 of the third and fourth sides of the innermost groove 6131 of the pressed wave portion 613 and the width W4 of the third and fourth sides of the innermost protrusion 6231 of the molded wave portion 623.

The innermost peak 11021 of the wave portion 1102 is defined as a first side and a second side on two sides in the first direction D1 and is respectively close to the two ends of the long axis 11011 of the center hole 1101.

[0090] like Figure 10 and Figure 11 As shown, the present invention provides a speaker wire damper fabric 200 with unequal width peaks to improve the shape of the center hole, comprising a base material 30, a speaker wire damper 100, a plurality of wire assemblies 20, and a resin solidifying layer 130. The base material 30 is woven from a plurality of warp yarns 11 and a plurality of weft yarns 12 (see Figure 2The speaker wire damper 100 is disposed on a substrate 30 and includes a body 110. The body 110 has a central hole 1101, a wavy portion 1102, and an outer portion 1103. The central hole 1101 is elliptical in shape, with a major axis 11011 of the central hole 1101 parallel to a first direction D1, and a minor axis 11012 of the central hole 1101 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 wave portion 1102 includes multiple peaks 11021 and multiple troughs 11022. The innermost peak 11021 of the wave portion 1102 is defined as a first side and a second side on two sides in the first direction D1 and is respectively close to the two ends of the long axis 11011 of the center hole 1101.

Figure 13 FIG. 1 is a perspective view of a first embodiment of a speaker wire damper 100 according to the present invention. Figure 14 yes Figure 13 After the speaker wire damper fabric 200 is manufactured, the following steps are further included: Step S50, such as Figure 1 、 Figure 12 、 Figure 13 and Figure 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 , separating the speaker wire damper 100 from the substrate 30 . The innermost peak 11021 of the wavy portion 1102 shrinks into a circular shape, shrinking the center hole 1101 into a circular shape.

Figure 16 FIG. 1 is a perspective view of a second embodiment of a speaker wire damper 100A according to the present invention. Figure 17 yes Figure 16 Schematic diagram of area B. Figure 15 、 Figure 16 and Figure 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 assembly 20A forms a multifilament wire body with a circular cross section.

[0093] Figure 18 It is a perspective view of step S10 of the third embodiment of the manufacturing method of the present invention. Figure 19 FIG. 1 is a perspective view of a speaker wire damper 100B according to a third embodiment of the present invention. Figure 20 yes Figure 19 Schematic diagram of region C. Figure 18 、 Figure 19 and Figure 20 As shown, in terms of method, the third embodiment differs from the aforementioned embodiments in that: in step S10, the conductors 21 are interwoven and braided with each other so that each conductor assembly 20B forms a multifilament wire body with a flat cross section.

[0094] In summary, because the weft yarn 12 has superior stretchability and elastic recovery compared to the warp yarn 11, when hot-pressing the speaker wire damper fabric 200, an elliptical center hole 1101 and a non-circular peak 11021 at the innermost portion of the wavy portion 1102 are formed. After the speaker wire damper 100 is separated from the substrate 30, the innermost peak 11021 of the wavy portion 1102 shrinks into a circular shape, causing the center hole 1101 to shrink into a circular shape. Consequently, after the speaker is assembled, the inner side of the circular center hole 1101 rests completely against the voice coil, allowing the speaker wire dampers 100, 100A, and 100B to securely hold the voice coil in the gap between the magnet cores, preventing the voice coil from shaking.

[0095] 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.
