path switching units 20c and 20d and the audio path switching unit 36 change the input, output,
and input / output of audio signals when communicating with the coupler 20, the cellular phone
2B and the audio reproduction device 3B in the headphones 1B This makes it easy to distinguish
the voices of
That is, the user can use the mobile phone 2B and the audio reproduction device 3B while
wearing the headphone 1B.
[0077]
In addition, as long as the headphone 1B includes a speaker and a microphone, any headphone
can be used.
In addition, the speaker and the microphone may be separately connected.
[0078]
Further, the high-frequency coupler 30, the high-frequency signal processing unit 30a, and the
audio path switching unit 36 of the audio reproduction device 3B are independently made up to
constitute a communication device, for example, achieved separately by a dongle connectable to
the audio reproduction device. May be

Thereby, in the general-purpose audio reproduction apparatus, the communication function and
the audio path switching function can be achieved.
Also, the communication device may be made independent in the mobile phone 2B as well.
