Abstract
Description
Technical Field
[0001] The utility model relates to a speaker wire spring and a manufacturing method thereof, in particular to a speaker wire spring with periodic cross-line. 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 speaker wire damper includes a body, a four-wire assembly and a resin solid layer. The body includes a plurality of warp yarns and a plurality of weft yarns, and the weft yarns are interwoven with the warp yarns and the wire assembly. Each wire assembly is composed of a plurality of wires. The weft yarns form two elastic adjustment areas between the warp yarns closest to the two sides of the wire assembly and the wire assembly, and the widths of the elastic adjustment areas are equal and greater than the distance between the warp yarns. The resin solid layer covers the surfaces of the warp yarns, the weft yarns and the 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 the elastic adjustment area.
[0005] However, the two adjacent weft yarns pass through the upper and lower parts of the conductor assembly respectively. Although the weft yarns can firmly fix the conductor assembly by interlacing and weaving, the fixing force of the weft yarns is quite large, which affects the elasticity of the conductor assembly, resulting in the effect of the elastic adjustment areas jointly adjusting the hardness, elasticity and toughness of the conductor setting area not being as expected. The conductor setting area is still harder than other areas of the speaker conductor elastic wave, and the elasticity and toughness of the conductor setting area are still worse than those of other areas of the speaker conductor elastic wave. Therefore, the hardness, elasticity and toughness of the speaker conductor elastic wave are uneven, resulting in uneven elastic recovery force and fatigue resistance of the speaker conductor elastic wave, and the speaker conductor elastic wave is easily deformed, which in turn affects the sound quality of the speaker output. Utility Model Content
[0006] The main purpose of the utility model is to provide a periodic cross-line speaker conductor elastic wave, which can reduce the force of the weft yarn fixing conductor combination.
[0007] In order to achieve the aforementioned purpose, the utility model provides a speaker conductor wave with periodic cross-line, including a body, a plurality of conductor combinations and a resin solid layer.

The conductor combinations are arranged at intervals with the warp yarns, extend linearly along the first direction, are parallel to each other with the warp yarns, and periodically cross the top and bottom of the weft yarn combinations along the first direction, wherein each of the conductor combinations is composed of a plurality of conductors, each of the conductors is a monofilament body, and the area where the weft yarn combinations are interlaced with each of the conductor combinations is defined as a conductor setting area. 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 weft yarns jointly form a first elastic adjustment region 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 region 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 region and the second elastic adjustment region are equal, and the distance between the warp yarns is smaller than the widths of the first elastic adjustment region and the second elastic adjustment region.

[0050] The following is a more detailed description of the implementation of the present invention with reference to the accompanying drawings and element symbols, so that those skilled in the art can implement it accordingly after reading this specification.
[0051] Figure 1 It is a flow chart of the manufacturing method of the utility model. Figure 2 It is a schematic diagram of step S10 and step S20 of the first embodiment of the manufacturing method of the utility model. Figure 3 Schematic diagram of steps S20 to S50 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 periodic cross-line, comprising the following steps:
[0052] Step S10, as Figure 1 and Figure 2 As shown, a plurality of warp yarns 10 and two conductor assemblies 20 are arranged at intervals, and the warp yarns 10 and the conductor assemblies 20 extend in a straight line along a first direction and are parallel to each other. Each conductor assembly 20 is composed of a plurality of conductors 21, each conductor 21 is a monofilament, and the conductors 21 are arranged at intervals. In other words, the intervals between the warp yarns 10 and the conductors 21 are the same.
[0053] Step S20, as Figure 1 and Figure 2As shown, a plurality of weft yarns 31 are interwoven with the warp yarns 10 and the conductor assemblies 20 along a second direction to weave a substrate 40. The first direction is perpendicular to the second direction, three adjacent weft yarns 31 are defined as a weft yarn assembly 30, each conductor assembly 20 periodically crosses over the top and bottom of the weft yarn assembly 30 along the first direction, and the area where the weft yarn assembly 30 and the conductor assembly 20 are interwoven is defined as two conductor arrangement areas 41. More specifically, the so-called periodic crossing means that each conductor assembly 20 crosses over the weft yarn assembly 30 in a continuous and staggered manner. For example, first, each conductor assembly 20 crosses over the top of the three weft yarns 31 of one weft yarn assembly 30, then each conductor assembly 20 crosses over the bottom of the three weft yarns 31 of another weft yarn assembly 30, and so on.
[0054] In some embodiments, each weft yarn combination 30 has at least two weft yarns 31. First, each conductor assembly 20 spans over the top of two weft yarns 31 of one weft yarn combination 30, then each conductor assembly 20 spans under the bottom of two weft yarns 31 of another weft yarn combination 30, and so on.
[0055] In some embodiments, the number of weft yarns 31 of the weft yarn combinations 30 may be different. For example, some weft yarn combinations 30 have two weft yarns 31, and some weft yarn combinations 30 have three weft yarns 31. First, each conductor assembly 20 crosses over the top of two weft yarns 31 of one weft yarn combination 30, then each conductor assembly 20 crosses under the three weft yarns 31 of another weft yarn combination 30, then each conductor assembly 20 crosses over the top of two weft yarns 31 of another weft yarn combination 30, then each conductor assembly 20 crosses under the three weft yarns 31 of yet another weft yarn combination 30, and so on.
[0056] 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.
[0057] 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 ).
[0058] Step S50, as Figure 1 and Figure 3As shown, a hot press molding device 70 includes a molding mold 71 and a heating device (not shown), and the molding mold 71 includes an upper mold 711 and a lower mold 712. When the upper mold 711 and the lower mold 712 are molded together 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 the warp yarns 10, the conductors 21 and the weft yarns 31, thereby hot press molding a speaker conductor damper 100 on the substrate 40. The weft yarns 31 jointly 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 together 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.
[0059] 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 .
[0060] Figure 4 It is a three-dimensional diagram of a first embodiment of a speaker wire damper 100 of the present invention. Figure 5 yes Figure 4 Schematic diagram of area A. Figure 4 and Figure 5 As shown, the utility model 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 .
[0061] The body 110 includes a plurality of warp yarns 10 and a plurality of weft yarns 31 . The warp yarns 10 are arranged at intervals 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 .
[0062] In some embodiments, the number of weft yarns 31 in each weft yarn combination 30 is at least two.
[0063] In some embodiments, the number of weft yarns 31 of the weft yarn combinations 30 may be different. For example, the number of weft yarns 31 of some weft yarn combinations 30 is two, and the number of weft yarns 31 of some weft yarn combinations 30 is three.
[0064] The conductor assemblies 20 are arranged at intervals from the warp yarns 10, extend in a straight line along the first direction, are parallel to the warp yarns 10, and periodically cross over the top and bottom of the weft yarn assemblies 30 along the first direction. More specifically, the so-called periodic crossing refers to continuous staggered crossing. For example, each conductor assembly 20 first crosses over the top of one weft yarn assembly 30, then crosses over the bottom of another weft yarn assembly 30, and so on. Among them, each conductor assembly 20 is composed of a plurality of conductors 21, each conductor 21 is a monofilament line body, and the conductors 21 are arranged at intervals. The area where the weft yarn assembly 30 and the conductor assemblies 20 are interlaced is defined as a two-conductor arrangement area 41. 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, and the weft yarns together form a second elastic adjustment area 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 area 101 and the second elastic adjustment area 102 are equal, and the distances between the warp yarns 10 are smaller than the widths of the first elastic adjustment area 101 and the second elastic adjustment area 102.
[0065] The resin solid layer 130 covers the surfaces of the warp yarns 10 , the weft yarns 31 and the conductive wires 21 .
[0066] Figure 6 Schematic diagram of step S10 and step S20 of the second embodiment of the manufacturing method of the utility model. Figure 6 As shown, in terms of method, the difference between the second embodiment and the first embodiment is that step S10 further includes: the conductors 21 are twisted so that each conductor combination 20A forms a multifilament wire body with a circular cross-section.
[0067] Figure 7 It is a three-dimensional diagram of a second embodiment of a speaker wire damper 100A of 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.
[0068] Fig. 9 Schematic diagram of step S10 and step S20 of the third embodiment of the manufacturing method of the utility model. Fig. 9As shown, in terms of method, the difference between the third embodiment and the aforementioned embodiment is that step S10 further comprises: 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.
[0069] Fig.10 It is a three-dimensional diagram of a third embodiment of a speaker wire damper 100B of the present invention. Fig.11 yes Fig.10 Schematic diagram of area C. Fig.10 and Fig.11 As shown, in terms of structure, 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.
[0070] In summary, the utility model can reduce the force of the weft yarn 31 fixing the wire assembly 20, 20A, 20B by setting the wire assembly 20, 20A, 20B in a periodic cross-line manner, reduce the influence of the weft yarn 31 on the wire assembly 20, 20A, 20B, and make the wire assembly 20, 20A, 20B have better elasticity.
[0071] It is worth mentioning that the utility model can also adjust the hardness, elasticity and toughness of the wire setting area 41 by setting the wire combination 20, 20A, 20B in a periodic cross-line manner in conjunction with the first elastic adjustment area 101 and the second elastic adjustment area 102, so that the wire setting area 41 becomes softer and the elasticity and toughness are improved. The hardness, elasticity and toughness of the wire setting area 41 and the wire combination 20, 20A, 20B are equivalent to the hardness, elasticity and toughness of other areas of the speaker wire damper 100, 100A, 100B. Therefore, the speaker wire damper 100, 100A, 100B has uniform hardness, elasticity and toughness, and thus has uniform elastic recovery force and fatigue resistance, is not easy to deform and crack, and improves the sound quality of the speaker output.
[0072] 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.
