。First, to explain the embodiment shown in FIGS. 2 and 3, reference numeral 5 denotes a coil bobbin constructed by winding a rectangular material having a copper foil 7 formed on one side of a resin film 6 into a cylindrical shape. Both ends are wound with a constant gap.
しかもこのコイルボビン５の中間部には銅箔７を２分す
るためのエツチングによるスリット８が形成されている
。Furthermore, a slit 8 is formed in the middle of the coil bobbin 5 by etching to divide the copper foil 7 into two.
また、このコイルボビン５の外周面には上記銅箔７かく
るように構成されており、このコイルボビン５の下部外
周には細銅線を巻回してコイル９が形成されている。The coil bobbin 5 is constructed such that the copper foil 7 is wrapped around the outer circumferential surface thereof, and a coil 9 is formed by winding a thin copper wire around the lower outer circumference of the coil bobbin 5.
このコイル９の両端の引出線１０はコイルボビン５の２
分割された銅箔７に半田などにより接続され、さらにこ
のそれぞれの銅箔７には金糸線などからなる外部リード
線１１が半田付けにより接続されている。The lead wires 10 at both ends of this coil 9 are connected to the two ends of the coil bobbin 5.
The divided copper foils 7 are connected to each other by soldering or the like, and external lead wires 11 made of gold thread or the like are further connected to each of the copper foils 7 by soldering.
また、第４図、第５図に示す実施例は短冊状のボビン素
体の上部に切込み１２を入れてこの切込み１２を入れた
部分を伸ばして上記外部リード線１１として利用しよう
とするものである。Further, in the embodiment shown in FIGS. 4 and 5, a notch 12 is made in the upper part of the rectangular bobbin body, and the part where the notch 12 is made is extended and used as the external lead wire 11. be.
さらに第６図に示すものは、あらかじめ円筒状に成形さ
れた樹脂フィルム６の外表面に銅箔７を形成したものを
コイルボビン５とし、この銅箔７に２本のエツチングに
よるスリット８を形成して銅箔７を２分したものであり
、コイルボビン５としての真円度の向上を計ったもので
あり、コイル９の引出線１０、外部リード線１１を２分
された銅箔７に接続してボイスコイルとしたものである
。Furthermore, in the coil bobbin 5 shown in FIG. 6, a copper foil 7 is formed on the outer surface of a resin film 6 previously formed into a cylindrical shape, and two slits 8 are formed in this copper foil 7 by etching. The copper foil 7 is divided into two parts to improve the roundness of the coil bobbin 5, and the lead wire 10 and external lead wire 11 of the coil 9 are connected to the copper foil 7 divided into two parts. This is a voice coil.
なお、コイルボビン５の樹脂フィルム６上の銅箔７の代
りにニッケル箔などの半田付可能な金属層を設けること
もできる。Note that instead of the copper foil 7 on the resin film 6 of the coil bobbin 5, a solderable metal layer such as nickel foil may be provided.
このようにコイルボビン５の外表面の金属層７をコイル
９の引出線１０と外部リード線１１との中継ターミナル
として利用することができる。In this way, the metal layer 7 on the outer surface of the coil bobbin 5 can be used as a relay terminal between the lead wire 10 of the coil 9 and the external lead wire 11.
以上のように本考案のスピーカ用ボイスコイルは構成さ
れるため、コイルボビンの外表面の金属層にコイルの引
出線、外部リード線を接続できてその半田付けなどによ
る接続作業が容易となり、しかも接続面積も大きくなっ
て断線０発生も著しく少なくすることができ、しかも、
コイルの発熱を金属層で有効に放散させて耐熱性に優れ
たものとすることもできるなどの利点をもち、実用的価
値の犬なるものである。As the speaker voice coil of the present invention is constructed as described above, the coil lead wire and external lead wire can be connected to the metal layer on the outer surface of the coil bobbin, making connection work such as soldering easy. The area becomes larger and the occurrence of wire breakage can be significantly reduced, and moreover,
It has the advantage of being able to effectively dissipate the heat generated by the coil through the metal layer, making it highly heat resistant, making it of great practical value.
