The control means switches the first switch to the receiving channel side in response to the incoming call.

[0009] Alternatively, the portable telephone further includes a ringing tone generating means and a control means. The ringing tone generating means generates a ringing tone in response to an incoming call and supplies the ringing tone to at least one of the left and right channels. The control means switches the first changeover switch to the receiving channel side in response to the user's reception response operation.

Therefore, when there is an incoming call, a ringing tone is output from one speaker of the headphones. Therefore, the user can hear the ringing tone even if there is an incoming call even while listening to music.

[0011] Preferably, the headphones have a microphone. The mobile phone further includes a transmitting circuit and a second
And a second changeover switch. The transmission circuit operates in a call mode and has a transmission channel for transmitting a transmission signal. The second terminal is connected to the other speaker or microphone of the headphones. The second changeover switch connects the second terminal to the transmission channel in the call mode, and connects the second terminal to the other of the left and right channels in the music playback mode.

When the portable telephone is in the music reproduction mode, the other channel of the reproduced music is given to the other speaker of the headphones via the second terminal. On the other hand, when the mobile phone is in the call mode, the transmission signal generated by the microphone is provided to the transmission circuit via the same second terminal.

According to another aspect of the present invention, a headphone includes a first speaker, a first terminal, a second speaker, a microphone, a second terminal, and a changeover switch. The first terminal is connected to a first speaker.
The changeover switch connects the second terminal to one of the second speaker and the microphone.

In this headphone, a microphone and a second
Speaker is switched. Preferably, the headphones further include an arm for supporting the microphone. The changeover switch includes a first contact, a second contact, a common contact, and a rotation mechanism. The first contact is connected to a second speaker. The second contact is connected to a microphone. The common contact is connected to the second terminal. The rotation mechanism is for mounting the arm rotatably. The rotation mechanism connects the second contact to the common contact while rotating the arm to move the microphone near the user's mouth, and rotates the arm to move the microphone to a position other than near the user's mouth. Then, the first contact is connected to the common contact.

Therefore, the user can easily switch between the microphone and the second speaker simply by rotating the arm and moving the microphone up and down.
