本考案は、スピーカーのボイスコイルに電気信
号を供給するための錦糸線に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tinsel wire for supplying electrical signals to the voice coil of a speaker.

た構造を有する。 Generally, as shown in FIGS. 3 and 4, a speaker has a vibration system configured by supporting a frame 3 around the periphery of a cone-shaped diaphragm 2 with a voice coil 1 bonded to the top. An electronic board 4 is attached to the frame 3, and one end of a tinsel wire 5 is soldered to the terminal board 4, and the other end is wound around the voice coil 1. It has a structure in which the voice coil conducting wire 6 is soldered, and the soldered portion is bonded to the midsection of the cone-shaped diaphragm 2 or a portion of the voice coil 1 using a rubber-based or polyamide-based solvent-based adhesive 7.
そして、上記錦糸線５は、上記振動系の振動に
伴つて振動あるいは共振して、特に、低周波領域
であつて高入力の場合、振動系の振幅が大きいた
め、錦糸線５が接続部で断線することがある。 The tinsel wire 5 vibrates or resonates with the vibration of the vibration system, and the amplitude of the vibration system is large, especially in the low frequency region and high input, so the tinsel wire 5 is at the connection part. There may be a disconnection.
そこで、従来は、錦糸線５の両端部の接続部に
柔軟なシリコン系樹脂その他の樹脂塗料８を塗布
していた。 Therefore, in the past, a flexible resin paint 8 such as a silicone resin was applied to the connecting portions of both ends of the tinsel wire 5.
［考案が解決しようとする問題点］
従来のシリコン系樹脂その他の樹脂塗料８は、

れたりして生産性の点で不利となる。[Problems to be solved by the invention] Conventional silicone resin and other resin paints 8 are
Although some vibration loss can be obtained, it is not sufficient and breakage of the tinsel wire 5 cannot be completely prevented. Moreover, if the tinsel wire 5 is made to have a large diameter in order to prevent wire breakage, the efficiency of the speaker will be reduced. Furthermore, since conventional silicone resin and other resin paints are solvent-based, they take a long time to dry, and the resin paint 8 flows during the drying process, which is disadvantageous in terms of productivity.
［問題点を解決するための手段］
本考案は、錦糸線５の両端部または当該両端部
を含む一部あるいは全部に紫外線硬化型樹脂塗料
を塗布して被膜９を形成したことを特徴とするも
のである。[Means for Solving the Problems] The present invention is characterized in that a coating 9 is formed by applying an ultraviolet curable resin paint to both ends of the tinsel wire 5 or to a part or all of the tinsel wire 5 including the both ends. It is something.
［作用］

来のもの（0.3〜0.5）に比べて1.1〜1.5と大きい。
そのため、振動系の振動やそれに伴う錦糸線５の
振動あるいは共振が有効に吸引される。[Function] When ultraviolet curable resin paint is irradiated with ultraviolet rays, it cures instantly within several seconds to tens of seconds, and the Young's modulus after curing is 2 to 5 × 10 7 dyn/cm 2 , which is higher than that of silicone resin. (Young's modulus after curing: 4-7×10 7 dyn/
cm 2 ), and the vibration loss tan δ is also larger at 1.1 to 1.5 compared to the conventional one (0.3 to 0.5).
Therefore, the vibration of the vibration system and the accompanying vibration or resonance of the tinsel wire 5 are effectively absorbed.

Components equivalent to those of the conventional example shown in FIGS. 3 and 4 are designated by the same reference numerals, and their explanation will be omitted.

The resin paint will not flow. Further, it is possible to prevent the tinsel wire 5 from breaking at its bonded portion due to the vibration of the cone-shaped diaphragm 1 and the accompanying vibration or resonance of the tinsel wire 5.
