A mouse device includes a USB transceiver, an MP3 decoder, and an FM transmitter. The USB transceiver receives the audio data S(MP3), which is audio data that has been compressed in the MP3 format, from a computer, and outputs the audio data to the MP3 decoder. The MP3 decoder decodes the audio data S(MP3), thereby converting the audio data S(MP3) into an analog signal. The FM transmitter converts the analog signal into a radio frequency signal, and transmits the radio frequency signal thus converted to an audio playback device.
