Abstract

　本発明に係る振動装置は、振動板と、振動板を振動可能に支持する支持系部材と、振動板に取り付けられた筒状のボイスコイルボビンと、ボイスコイルボビンの内周側および外周側の少なくとも一方に配置され、振動板の振動方向に着磁されてボイスコイルボビンと対向する側に磁気ギャップを形成するマグネットと、磁気ギャップ内に配置されるようにボイスコイルボビンに取り付けられ、入力電気信号が入力されて発生した駆動力により振動板およびボイスコイルボビンを振動させるボイスコイルと、磁気ギャップ内における平衡位置に配置されるようにボイスコイルボビンに取り付けられ、ボイスコイルボビンとともに振動したとき、平衡位置から離れる方向に磁気的吸引力が作用する磁性体部材とを備える。
