Claims (1)

  1. 【実用新案登録請求の範囲】 1 スピーカの音量が、前もつて設定した値を越
    えた場合スピーカの音声入力回路の電流(電圧)
    を検出する検出器6またはスピーカの出力音量(
    音圧)を検出する検出器7が電気信号を出し、そ
    の電気信号により音量調整器2が作動し、スピー
    カ音量を自動的に設定値まで減少させる。または
    、別に設けた音量過大警告灯8を点灯させる回路
    を有することを特徴とする音響装置。 2 音響装置の電源スイツチ5をONまたはOF
    Fに操作した時の電気信号で音量調整器2が自動
    的に作動し、予め設定したスピーカの適正音量の
    復帰することを特徴とする音響装置。
