A transmitting device(400) mixes an audio signal inputted through a portable terminal(100) with the voice signal inputted through the microphone(300), modulates the mixed signal, and transmits the modulated signal. A receiving device(500) demodulates the modulated signal transmitted from the transmitting device(400), and outputs the demodulated signal to an audio device(600). |
