ABSTRACT:
A radio terminal is disclosed which can be switched into a talking mode simply when a telephone call terminates while sound data of music or the like is being played back and besides can assure a good talking quality. A stereo headphone microphone unit connected to a portable telephone set body includes first and second earphones and a microphone disposed in the proximity of the second earphone. Except during telephone conversation, music played back by a music playback section is enjoyed using the earphones. If a termination detection section detects termination of a call, then if music is being played back, then the playback is stopped temporarily, and a first control section supplies a ringing tone only to the first earphone and enables telephone conversation by means of the first earphone and the microphone. When the telephone conversation comes to an end, playback of the music playback section is started from a portion of the music at which the playback was temporarily stopped. Playback of music by the music playback section is stopped if a battery remaining amount detection section detects that the remaining amount of the battery becomes lower than the lowest level with which telephone conversation is possible. During telephone conversation, no sound is outputted from the second earphone. Therefore, an echo can be prevented from being transmitted to the other party of telephone communication.
