Abstract text

According to an aspect of the present invention, there is provided a communication device including: an audio signal input member configured to receive a first audio signal; a high-frequency coupler configured to receive a second audio signal, the second audio signal based on a high-frequency signal transmitted from an external high-frequency coupler by communicating with the external high-frequency coupler through electric field coupling; an output unit configured to output one of the first audio signal and the second audio signal; and a switch configured to switch an output of the output unit between the first audio signal and the second audio signal based on a status of communication between the high-frequency coupler and the external high-frequency coupler.
