Description
不飽和ポリエステル樹脂(日本触媒(株)製;N350L) :100(部)
低収縮化剤(日本油脂(株);モディパーS501) :5
パーオクタO(日本油脂(株)) :1.3
一方、表側にポリエチレンナフタレート(PEN)繊維の撚りのない平織り(帝人製 糸番手1100×1100(dtex) 密度17×17(本/inch) 目付け166g/m2)にメラミン樹脂5部を含浸、乾燥した織布とテクノーラ不織布(目付け:60g/m2)を15cm角に切断したものを2層積層して基材とする。約20cm角のステンレス板の中央に直径約16cmの円形の穴を開けた冶具をクランプ゜とし、このクランプ2枚の間に積層した基材を挟んだ後、調合した上記の不飽和ポリエステル溶液(約5g)をクランプした基材の中央付近に滴下する。図4の振動板形状のマッチドダイ金型で130℃で30秒間成形することにより口径16cm、厚さ0.35mmの振動板を得た。取付部7は下側金型のみに掘り込みが設けてあるため、振動板1の背面側のみに不飽和ポリエステル樹脂が硬化して形成される。
5 第1振動板部分
6 第2振動板部分
7 取付部
Claims (4)

該第1振動板部分および該第2振動板部分が、基材に熱硬化性樹脂が含浸されてなり、該取付部が、該熱硬化性樹脂が硬化されて成形されている、スピーカー振動板。 - 前記熱硬化性樹脂が不飽和ポリエステル樹脂である、請求項1に記載のスピーカー振動板。
- 請求項1または2に記載のスピーカー振動板を備える、スピーカー。
- 基材の第1振動板部分および第2振動板部分となるべき部分に熱硬化性樹脂を含浸する行程と、
金型の、ボイスコイルボビンの一端が接着される取付部を形成する部分に該熱硬化性樹脂を供給する行程と、
該含浸した熱硬化性樹脂を硬化させて該第1振動板部分および該第2振動板部分を形成すると同時に、該金型の取付部を形成する部分に供給された熱硬化性樹脂を硬化させて該取付部を形成する行程とを含む、スピーカー振動板の製造方法。
