Claims (6)
- 1つの開口部が設けられた高剛性の箱体内に支持部を介して振動素子を配設してなり、前記振動素子の駆動源となる駆動体が面振動型の平板体であり、前記振動素子の周りの前記箱体内の主たる空間を分断すること無く1つとし、前記開口部に合わせて前記振動素子の振動を出力する振動出力部を前記箱体の外面に露出させ、前記開口部またはその近傍以外では前記駆動体への交流電圧印加により前記振動素子全体が長手方向に湾曲振動するときの振動の節となる位置近傍に弾性部材または粘弾性部材により前記支持部を設け、該振動の振幅が最大となる位置近傍に前記振動出力部を設けたことを特徴とする骨伝導スピーカ。
- 前記駆動体の長手方向両端に錘部材を接合し、湾曲振動の節が前記振動素子の長手方向の両端に近くなるようにし、前記振動出力部となる前記振動素子の中央部の振幅がより大きくなるようにしたことを特徴とする請求項1記載の骨伝導スピーカ。
- 前記駆動体はバイモルフ型圧電セラミックからなることを特徴とする請求項1または2記載の骨伝導スピーカ。
- 前記駆動体は短冊形のバイモルフ型圧電セラミックを並置してなることを特徴とする請求項3記載の骨伝導スピーカ。
- 前記振動出力部の人体頭部への接触面は、人体頭部への押圧により前記振動素子の支持部材が弾性変形し、前記箱体の内部方向に後退した位置での前記接触面と、前記箱体の開口部の外周部平面とが、略同一面になるように形成されたことを特徴とする請求項1から4のいずれか1項に記載の骨伝導スピーカ。
- 開口を有する箱体内に支持部を介して振動素子を配設してなる骨伝導スピーカにおいて、前記振動素子の駆動源となる駆動体は面振動型の平板体であり、該駆動体への交流電圧印加により前記振動素子全体が長手方向に湾曲振動するときの振動の節となる位置近傍に弾性部材または粘弾性部材により前記支持部を設け、該振動の振幅が最大となる位置近傍に振動を出力する部分を設けたことを特徴とする骨伝導スピーカ。
