Claims (4)
- 一定の長さを有する板状の圧電素子における長手方向の両端部と、該圧電素子と略平行に配置された平板状もしくは湾曲した板状の少なくとも1つの弾性体の両端部とが結合され、前記圧電素子の長手方向の伸縮に応じて前記弾性体が座屈変形することにより前記長手方向と直交する方向に振動する振動系が形成され、該振動系の重心移動によって発生する力を被振動体への駆動力としたことを特徴とする音響信号発生用圧電装置。
- 前記圧電素子が長手方向もしくは該長手方向と直行する方向に積層された積層型圧電素子よりなることを特徴とする、請求項1に記載の音響信号発生用圧電装置。
- 前記弾性体の1つにおける中央部が、被振動体としての筐体もしくはパネルに接合されたことを特徴とする、請求項1または請求項2に記載の音響信号発生用圧電装置。
- 前記弾性体は前記圧電素子の主面の両側に配置され、片側に配置された弾性体の中央部が、被振動体としての筐体もしくはパネルに接合され、他の側に配置された弾性体の中央部には錘が付加されたことを特徴とする、請求項1または請求項2に記載の音響信号発生用圧電装置。
