録請求の範囲第(1)項記載の音響装置。[Scope of Claim for Utility Model Registration] (1) An audio device that uses a battery as a power source and emits a signal from a signal source circuit from a speaker, which includes a volume adjustment means for adjusting the level of the reproduced low frequency signal. , detection means for detecting whether or not the low frequency signal adjusted by the volume adjustment means is supplied and the level of the low frequency signal continues to be below a predetermined level for a predetermined time; and a detection means disposed on the power supply line. is,
and a switch means controlled based on the detection output of the detection means, and when the low frequency signal level in the detection means continues to be below a predetermined level for a predetermined time, the switch means is controlled based on the detection output from the detection means. An audio device characterized in that said switch means is controlled to cut off a power supply path. (2) A utility model registration request characterized in that the signal source circuit is a tape recorder, and the low frequency signal level detection period of the detection means is set longer than the inter-song no-signal part detection period in the tape recorder. Sound equipment described in scope item (1).
