【考案の詳細な説明】
本考案は高弾性の長繊維を集束した糸に熱硬化
性樹脂を含浸したものを円筒状に巻回したものを
加熱硬化して構成したボビンを用いたスピーカ用
ボイスコイルに係り、軽量で剛性に優れたものを
提供しようとするものである。[Detailed description of the invention] This invention is a speaker voice using a bobbin made by heating and curing a cylindrical winding of a thread made of highly elastic long fibers impregnated with a thermosetting resin. The purpose is to provide a coil that is lightweight and has excellent rigidity.
従来のスピーカ用ボイスコイルとしては第１図
に示すようにクラフト紙や金属箔よりなる円筒状
ボビン１にマグネツトワイヤを巻付けてコイル２
を構成し、このコイル２の巻回されないボビン１
に補強紙３を貼付けて構成されていた。 As shown in Fig. 1, a conventional speaker voice coil is made by winding a magnet wire around a cylindrical bobbin 1 made of kraft paper or metal foil.
, and the bobbin 1 on which this coil 2 is not wound
It was constructed by pasting reinforcing paper 3 on the top.
クラフト紙をボビン１としたものは軽量で接着
性に優れているという特徴をもつ反面耐熱性に乏
しく、コイル２で発生した熱の放散性に乏しく、
剛性に劣るなどの欠点をもち、大入力用スピーカ
には用いることができないものであつた。 A bobbin 1 made of kraft paper is lightweight and has excellent adhesive properties, but on the other hand, it has poor heat resistance and poor dissipation of heat generated by the coil 2.
It had drawbacks such as poor rigidity, and could not be used for large-input speakers.
また、アルミニウムなどの金属箔でボビン１を
構成するものは耐熱性，放熱性，剛性に優れてい
るが、重量が重く、接着性に乏しいといつた欠点
があつた。 Further, the bobbin 1 made of metal foil such as aluminum has excellent heat resistance, heat dissipation, and rigidity, but has drawbacks such as being heavy and having poor adhesive properties.
さらに、これらのものは短冊状に切断した材料
を円筒状に巻回してボビン１とし、マグネツトワ
イヤを巻線し、補強紙３を貼付けて構成される
が、材料の両端で外方に広がろうとするため真円
形のボビン１とすることができず、これは温度上
昇するにつれて顕著となり、ギヤツプごすりを引
起すといつた問題があつた。 Furthermore, these items are constructed by winding a material cut into strips into a cylindrical shape to form a bobbin 1, winding a magnet wire thereon, and pasting reinforcing paper 3. The bobbin 1 cannot be made perfectly round because of the tendency to sag, and this becomes more noticeable as the temperature rises, causing the problem of gap rubbing.
このようなことから、スパイラル巻きによるボ
ビンも開発されているが紙のように接着性の材料
では容易に形成できるが、金属箔のスパイラル化
は困難で実用化されていないのが実状である。 For this reason, spiral-wound bobbins have been developed, but although they can be easily formed using adhesive materials such as paper, it is difficult to spirally wind metal foils, and the reality is that they have not been put to practical use.
本考案は以上のような従来の欠点を除去するも
のである。 The present invention eliminates the above-mentioned drawbacks of the prior art.
以下、本考案の実施例を図面第２図〜第４図に
より説明する。 Embodiments of the present invention will be described below with reference to FIGS. 2 to 4.
４は炭素繊維などの高弾性の長繊維を集束した
糸５に熱硬化性樹脂６を含浸したものを円筒状に
巻回し、加熱硬化して構成したエンドレスのボビ
ンで、このボビン４にはマグネツトワイヤを巻回
したコイル７が設けられて構成される。 Reference numeral 4 designates an endless bobbin constructed by winding a yarn 5 made of highly elastic long fibers such as carbon fibers and impregnating it with a thermosetting resin 6 into a cylindrical shape and hardening it by heating. A coil 7 wound with a net wire is provided.
すなわち、上記ボビン４は、炭素繊維，炭化ケ

ド系樹脂，フエノール系樹脂などの熱硬化性樹脂
６を含浸させる。この熱硬化性樹脂６の含浸量は
高弾性繊維に対して20〜40wt％が好ましい。こ
れを第４図Ｂに示すように100〜150℃で20〜25分
間加熱して熱硬化性樹脂６をセミキユアの状態に
してこれを巻取る。 That is, the bobbin 4 collects high elastic long fibers such as carbon fibers, silicon carbide fibers, and glass fibers into a belt-shaped yarn 5 having a thickness of 0.05 to 0.1 mm and a width of 0.5 to 2 mm, as shown in FIG. 4A. In this way, a thermosetting resin 6 such as a poxy resin, an imide resin, or a phenol resin is impregnated. The amount of impregnated thermosetting resin 6 is preferably 20 to 40 wt% based on the high elastic fiber. As shown in FIG. 4B, this is heated at 100 to 150 DEG C. for 20 to 25 minutes to semi-cure the thermosetting resin 6 and wind it up.
続いて、第４図Ｃに示すように円柱治具８に密
着巻きして円筒状とし、これを150〜200℃で30〜
60分間加熱して熱硬化性樹脂６を硬化させ、これ
を円柱治具８から抜き出し、第４図Ｄに示すよう
に所定寸法に切断してボビン４とする。 Next, as shown in FIG.
The thermosetting resin 6 is cured by heating for 60 minutes, and then extracted from the cylindrical jig 8 and cut into a predetermined size as shown in FIG. 4D to form the bobbin 4.
このような構成によるものはボビン４として軽
量で剛性に優れ、真円度を有し耐熱性，放熱性の
優れたものとなる。 The bobbin 4 having such a structure is lightweight, has excellent rigidity, has roundness, and has excellent heat resistance and heat dissipation.
