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システムを提供するものである。   この発明は、左右対称の筒状の共鳴壁と、この共鳴壁の左右両側に対称に設けられる一対または二対以上の振動部とを備え、対となる前記振動部が互いに同調して振動するように構成され、前記共鳴壁が、前記振動に共鳴するように可撓性材料によって形成されている一方、前記共鳴壁の内壁に沿わせて吸音部材を筒状に配置してあると共に、この吸音部材及び／又は前記振動部に振動抑制材を保持させてある。
