Abstract
Two systems each having an audio signal output unit are docked together, and audio signals are controlled in accordance with the characteristics of each system to thereby output sounds of good quality. If sounds are output from the two systems at the same time, the frequency band or sound volume of the audio signal is controlled in accordance with the characteristics of each speaker to thereby output sounds easy to listen.
