Abstract

　この発明は、悪影響を及ぼす振動を減らし正確で力強い音を生成することができる上、軽量化・小型化や製造に関するコストダウンの実現に寄与し、さらには宙吊り状態での設置が可能であり無重力下でも空気さえ存在すれば音を生成することができる無反動スピーカユニットを提供するものである。   この発明は、互いに同調して振動する一対の振動部を備え、各振動部が、電流を流すとマグネットにより駆動されるボイスコイルおよびボイスコイルボビンを有し、一方の振動部のボイスコイルボビンにコーンを設けると共に、他方の振動部のボイスコイルボビンにウエイト部材を設けてあり、また、二つのボイスコイルに流す電流の比を調整するための調整部を備えている。
