を特徴とする音場拡大切換回路。[Scope of Claim for Utility Model Registration] A mode discrimination signal generation circuit for transmitting a discrimination output for discriminating between a first mode for receiving dual-language broadcasting and a second mode for receiving monaural broadcasting or stereo broadcasting; and dual-language broadcasting. When a command signal specifying the output audio mode of the left and right speakers is given at the time of reception, a mode switching signal corresponding to the output audio mode of the speakers is generated according to this command signal, and the signal is set to L level or H level according to the command signal. Level up. It has a mode switching signal generation circuit that sends out an H output, and a sound field expansion circuit that outputs the input audio signal as it is in the off state and sends out a mixed output of the direct output and delayed output of the input audio signal in the on state, In an audio multiplex broadcast receiver in which the output audio modes of the two speakers are set according to the mode switching signal when receiving a bilingual broadcast, the sound field expansion circuit is turned on and off according to the input level, H. a control circuit that sends out a control signal; and a control circuit that sends out a control signal from the mode switching signal generation circuit in response to when the input discrimination output indicates a first mode. A sound field expansion switching circuit comprising: a switch that provides an H output to the control circuit.
