Abstract
An audio signal control circuit includes an adjustment signal generator that extracts a frequency band, which includes a frequency at which a frequency band shared by a low-range speaker and a frequency band shared by a high-range speaker overlap each other, to generate an adjustment signal Sck; a high-range outputter that subtracts the adjustment signal Sck from an audio signal Sa to generate a high-range audio signal SaH and outputs it to a high-pass filter; and a low-range outputter that adds the adjustment signal Sck to the audio signal Sa to generate a low-range audio signal SaL and outputs it to a low-pass filter.
