The switch processing section 12 selectively switches audio signals SAa, SAb, SAc from signal generation sections 2, 3, 4 and an external input audio signal SAd, while mixes a microphone output audio signal SAm and supplies it to a loudspeaker section 16. Since this device is not constituted by connecting each individual set with cables, it can be inexpensively constituted. An user is not required to operate section by section, each section can be easily operated by the key operating section 8.
