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 periodic cross-line 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] Conventional speaker wire dampers consist of a main body, a four-wire assembly, and a resin solidifying layer. The main body comprises multiple warp yarns and multiple weft yarns, the weft yarns interwoven between the warp yarns and the wire assemblies. Each wire assembly is composed of multiple wires. The weft yarns form two elastic adjustment zones between the warp yarns closest to the wire assembly and the wire assembly. The width of these elastic adjustment zones is equal and greater than the distance between the warp yarns. The resin solidifying layer covers the surfaces of the warp yarns, weft yarns, and wires.
[0004] Because the conductor assembly is harder than the warp and weft yarns, and the elasticity and toughness of the conductor assembly are worse than those of the warp and weft yarns, the existing speaker conductor damper can adjust the hardness, elasticity and toughness of the conductor setting area by setting these elastic adjustment areas.
[0005] However, two adjacent weft yarns, respectively passing above and below the conductor assembly, securely hold the conductor assembly in place through interlaced weaving. However, the substantial holding force exerted by these weft yarns affects the elasticity of the conductor assembly, resulting in the elasticity-adjusting regions collectively adjusting the hardness, elasticity, and toughness of the conductor mounting area less than expected. The conductor mounting area remains harder than the rest of the speaker conductor damper, and its elasticity and toughness remain inferior. Consequently, the hardness, elasticity, and toughness of the speaker conductor damper are uneven, resulting in uneven elastic recovery and fatigue resistance. This makes the speaker conductor damper susceptible to deformation, which in turn affects the sound quality of the speaker output. Summary of the Invention
[0006] The main purpose of the present invention is to provide a speaker conductor damper with periodic cross-line and a manufacturing method thereof, which can reduce the force of the weft yarn fixing conductor assembly.
[0007] To achieve the aforementioned objectives, the present invention provides a method for manufacturing a speaker wire damper with periodic crossovers, comprising the following steps: (a) arranging a plurality of warp yarns and a plurality of conductor assemblies at intervals, the warp yarns and the conductor assemblies extending linearly and parallel to each other along a first direction, wherein each conductor assembly comprises a plurality of conductors, each of which is a monofilament; (b) interweaving a plurality of weft yarns with the warp yarns and the conductor assemblies along a second direction to weave a base material, wherein the first direction is perpendicular to the second direction, at least two adjacent weft yarns define a weft yarn assembly, each conductor assemblies periodically crosses above and below the weft yarn assembly along the first direction, and the area where the weft yarn assembly and each conductor assemblies interweave defines a conductor arrangement area; (c) immersing the base material in a resin solution; (d) drying the base material to form a solid resin layer on the base material; (e) hot-pressing a speaker wire damper on the base material; and (f) separating the speaker wire damper from the base material.

[0011] In some embodiments, step (e) further includes: the weft yarns jointly form a first elastic adjustment area between a first side of each of the conductor combinations and the warp yarns closest to the first side of each of the conductor combinations, and the weft yarns jointly form a second elastic adjustment area between a second side of each of the conductor combinations and the warp yarns closest to the second side of each of the conductor combinations, the widths of the first elastic adjustment area and the second elastic adjustment area are equal, and the distance between the warp yarns is less than the widths of the first elastic adjustment area and the second elastic adjustment area.
[0012] To achieve the aforementioned objectives, the present invention provides a speaker wire damper with periodic crossover, comprising a main body, a plurality of wire assemblies, and a resin solidifying layer. The main body comprises a plurality of warp yarns and a plurality of weft yarns. The warp yarns are spaced apart and extend linearly and parallel to each other along a first direction. The weft yarns are interwoven with the warp yarns along a second direction, the first direction being perpendicular to the second direction. At least two adjacent weft yarns define a weft yarn assembly.

[0015] In some embodiments, the wires are interwoven and braided with each other, so that each wire combination forms a multifilament wire body with a flat cross-section.

[0055] The following describes the embodiments of the present invention in more detail with reference to the accompanying drawings and element symbols, 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 Schematic diagram of step S10 and step S20 of the first embodiment of the manufacturing method of the present invention. Figure 3 Schematic diagram of steps S20 to S50 of a first embodiment of the manufacturing method of the present invention. The present invention provides a method for manufacturing a speaker wire damper with periodic cross-line, comprising the following steps:
[0057] Step S10, as Figure 1 and Figure 2 As shown, multiple warp yarns 10 and two conductor assemblies 20 are spaced apart. The warp yarns 10 and the conductor assemblies 20 extend linearly and parallel to each other along a first direction. Each conductor assembly 20 is composed of multiple conductors 21, each of which is a monofilament. These conductors 21 are spaced apart. In other words, the warp yarns 10 and the conductors 21 are spaced the same distance apart.
[0058] Step S20, as Figure 1 and Figure 2As shown, a plurality of weft yarns 31 are interwoven with the warp yarns 10 and the conductive wire assemblies 20 along a second direction to weave a base material 40. The first direction is perpendicular to the second direction, and three adjacent weft yarns 31 define a weft yarn assembly 30. Each conductive wire assembly 20 periodically spans above and below the weft yarn assembly 30 along the first direction, and the area where the weft yarn assembly 30 and the conductive wire assemblies 20 are interwoven is defined as two conductive wire arrangement areas 41. More specifically, the so-called periodic spanning refers to the continuous and staggered spanning of the weft yarn assemblies 30 by each conductive wire assembly 20. For example, each conductive wire assembly 20 first spans above the three weft yarns 31 of one weft yarn assembly 30, then spans below the three weft yarns 31 of another weft yarn assembly 30, and so on.
[0059] In some embodiments, each weft yarn combination 30 has at least two weft yarns 31. First, each conductor assembly 20 spans over the two weft yarns 31 of one weft yarn combination 30, then each conductor assembly 20 spans under the two weft yarns 31 of another weft yarn combination 30, and so on.
[0060] In some embodiments, the weft yarn combinations 30 may have different numbers of weft yarns 31. For example, some weft yarn combinations 30 may have two weft yarns 31, while others may have three weft yarns 31. First, each conductive wire combination 20 spans over the two weft yarns 31 of one weft yarn combination 30, then spans under the three weft yarns 31 of another weft yarn combination 30, then spans over the two weft yarns 31 of yet another weft yarn combination 30, then spans under the three weft yarns 31 of yet another weft yarn combination 30, and so on.
[0061] Step S30, as Figure 1 and Figure 3 As shown, the substrate 40 is immersed in a resin solution 51 in a resin tank 50, so that the warp yarns 10, the conductive wires 21 and the weft yarns 31 absorb and adhere to the resin.
[0062] Step S40, as Figure 1 and Figure 3 As shown, a drying device 60 includes an upper baking plate 61 and a lower baking plate 62. The temperature of the upper baking plate 61 and the lower baking plate 62 is used to remove moisture and volatile substances in the resin on the substrate 40 to dry the substrate 40. At the same time, the resin penetrates into the substrate 40 and adheres to the warp yarns 10, the conductors 21 and the weft yarns 31 to form a resin solid layer 130 (see Figure 5 ).
[0063] Step S50, as Figure 1 and Figure 3As shown, a hot press forming device 70 includes a forming mold 71 and a heating device (not shown), and the forming mold 71 includes an upper mold 711 and a lower mold 712. When the upper mold 711 and the lower mold 712 are closed and pressurized on the substrate 40, the heating device is energized to increase the temperature of the upper mold 711 and the lower mold 712 to 190°C to 270°C, thereby softening the resin on the substrate 40. 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 to cover between the warp yarns 10, the conductors 21 and the weft yarns 31, thereby hot press-forming a speaker conductor damper 100 on the substrate 40. The weft yarns 31 together form a first elastic adjustment area 101 between a first side of the conductor assembly 20 and the warp yarns 10 closest to the first side of the conductor assembly 20 (see Figure 5 ), the weft yarns 31 form a second elastic adjustment region 102 between a second side of the conductor assembly 20 and the warp yarns 10 closest to the second side of the conductor assembly 20 (see Figure 5 ), the widths of the first elastic adjustment region 101 and the second elastic adjustment region 102 are equal, and the distances between the warp yarns 10 are smaller than the widths of the first elastic adjustment region 101 and the second elastic adjustment region 102.
[0064] Step S60, as Figure 1 and Figure 3 As shown, a cutting device 80 includes an upper cutter 81 and a lower cutter 82 . The upper cutter 81 and the lower cutter 82 cut the speaker wire damper 100 from the substrate 40 , so that the speaker wire damper 100 is separated from the substrate 40 .
[0065] 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 periodic cross-line speaker wire damper 100 , which includes a body 110 , a four-wire assembly 20 , and a resin solid layer 130 .
[0066] The body 110 includes a plurality of warp yarns 10 and a plurality of weft yarns 31 . The warp yarns 10 are spaced apart and extend linearly along a first direction and are parallel to each other. The weft yarns 31 are interwoven with the warp yarns 10 along a second direction. The first direction is perpendicular to the second direction. Three adjacent weft yarns 31 are defined as a weft yarn combination 30 .
[0067] In some embodiments, the number of weft yarns 31 in each weft yarn combination 30 is at least two.
[0068] In some embodiments, the weft yarn combinations 30 may have different numbers of weft yarns 31. For example, some weft yarn combinations 30 may have two weft yarns 31, while some weft yarn combinations 30 may have three weft yarns 31.
[0069] The conductor assemblies 20 are spaced apart from the warp yarns 10, extending linearly along a first direction, parallel to the warp yarns 10, and periodically crossing above and below the weft yarn assemblies 30 along the first direction. More specifically, periodic crossing refers to continuous, staggered crossing. For example, each conductor assembly 20 first crosses above one weft yarn assembly 30, then crosses below another weft yarn assembly 30, and so on. Each conductor assembly 20 is composed of multiple conductors 21, each of which is a monofilament, and spaced apart. The area where the weft yarn assemblies 30 and the conductor assemblies 20 are interwoven is defined as a second conductor arrangement area 41. The weft yarns 31 collectively form a first elastic adjustment region 101 between a first side of the conductor assembly 20 and the warp yarns 10 closest to the first side of the conductor assembly 20. The weft yarns collectively form a second elastic adjustment region 102 between a second side of the conductor assembly 20 and the warp yarns 10 closest to the second side of the conductor assembly 20. The widths of the first elastic adjustment region 101 and the second elastic adjustment region 102 are equal, and the distance between the warp yarns 10 is smaller than the widths of the first elastic adjustment region 101 and the second elastic adjustment region 102.
[0070] The resin solid layer 130 covers the surfaces of the warp yarns 10 , the weft yarns 31 and the conductive wires 21 .
[0071] Figure 6 FIG is a schematic diagram of step S10 and step S20 of the second embodiment of the manufacturing method of the present invention. Figure 6 As shown, in terms of method, the difference between the second embodiment and the first embodiment is that step S10 further includes: twisting the conductors 21 so that each conductor combination 20A forms a multifilament wire body with a circular cross section.
[0072] Figure 7 FIG. 1 is a perspective view of a second embodiment of a speaker wire damper 100A according to the present invention. Figure 8 yes Figure 7 Schematic diagram of area B. Figure 7 and Figure 8 As shown, in terms of structure, the conductors 21 are twisted so that each conductor combination 20A forms a multifilament wire body with a circular cross section.
[0073] Figure 9 FIG is a schematic diagram of step S10 and step S20 of the third embodiment of the manufacturing method of the present invention. Figure 9As shown, in terms of method, the difference between the third embodiment and the aforementioned embodiments is that step S10 further includes: 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.
[0074] 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, in terms of structure, 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.
[0075] In summary, the present invention can reduce the force of the weft yarn 31 fixing the conductor assembly 20, 20A, 20B by arranging the conductor assembly 20, 20A, 20B in a periodic cross-line manner, thereby reducing the influence of the weft yarn 31 on the conductor assembly 20, 20A, 20B, and making the conductor assembly 20, 20A, 20B have better elasticity.
[0076] It's worth noting that the present invention also allows the hardness, elasticity, and toughness of wire mounting area 41 to be adjusted by periodically arranging wire assemblies 20, 20A, and 20B in conjunction with first and second elasticity adjustment regions 101 and 102. This softens wire mounting area 41 and enhances its elasticity and toughness. The hardness, elasticity, and toughness of wire mounting area 41 and wire assemblies 20, 20A, and 20B are equivalent to those of the other regions of speaker wire dampers 100, 100A, and 100B. Consequently, speaker wire dampers 100, 100A, and 100B exhibit uniform hardness, elasticity, and toughness, resulting in uniform elastic recovery and fatigue resistance, making them less susceptible to deformation and cracking, and thus improving speaker sound quality.
[0077] 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.
