Description
次に、図1乃至図5を参照して、本発明の特徴をなすダンパー2の支持構造等について説明する。
上記の実施形態では、複数のダンパー、即ち、導電ダンパー2a及びダンパー2bの各内周縁部をボイスコイル4の巻き幅内に配置して、それらを連結部材8の下端近傍に固定するようにした。しかし、本発明の適用はこれには限らず、導電ダンパー2a及びダンパー2bのいずれか一方のダンパーだけを設けて、そのダンパーの内周縁部をボイスコイル4の巻き幅内に配置して、それを連結部材8の下端近傍に固定するようにしても構わない。この場合も、上記実施形態と同様の効果を得ることができる。
2a 導電ダンパー
3 ボイスコイルボビン
4 ボイスコイル
7 プレート
8 連結部材
8a 円筒部
d1 巻き幅
P1、P11 支点
