て、 音声信号中に予め決められた周波数より高域側
の信号が所定レベル以上含まれているか否かによ
つて、音声信号が狭帯域幅であるか否かを判定し
、判定信号を発生する帯域幅判定回路と、 ウーハの電源回路中に介挿され、帯域幅判定回
路から音声信号が狭帯域幅であることを表す判定
信号を受けて、その電源回路を遮断するウーハ電
源断続器と、 を有することを特徴とする音響装置。[Claim for Utility Model Registration] In an audio device equipped with a woofer as a speaker, the audio signal can be narrowed depending on whether the audio signal contains signals higher than a predetermined frequency at a predetermined level or higher. A bandwidth determination circuit that determines whether the audio signal has a narrow bandwidth and generates a determination signal, and a determination signal that is inserted into the woofer's power supply circuit and is sent from the bandwidth determination circuit to indicate that the audio signal has a narrow bandwidth. a woofer power interrupter that interrupts the power supply circuit in response to the received sound.
