- 音響振動発生用圧電素子としての積層型圧電素子と、前記積層型圧電素子における長さ方向の変位を拡大するための変位拡大機構と、前記変位拡大機構を介して前記積層型圧電素子を実装するための弾性体とを備え、更に、前記積層型圧電素子及び前記変位拡大機構を実装した前記弾性体を外耳道へ挿入する形態で使用に供され、
前記弾性体は、貫通穴を有する容器であって、該貫通穴内に前記変位拡大機構を介して前記積層型圧電素子を実装可能であると共に、実装状態で骨伝導音以外の気導音についても聴取可能であるように該積層型圧電素子と該貫通穴との間に隙間を持たせた構造であることを特徴とする骨伝導スピーカ。 - 請求項1記載の骨伝導スピーカにおいて、前記容器は、円筒形であることを特徴とする骨伝導スピーカ。
- 請求項1〜2の何れか一つに記載の骨伝導スピーカにおいて、前記積層型圧電素子を駆動して音響振動発生させるための駆動信号は、音声信号源から得られる音声信号に一定の直流バイアス電圧を印加して生成されたものであることを特徴とする骨伝導スピーカ。
