A terminal for communication provided with a microphone unit which can move between the place where the caller is present and which is away from the terminal main body and the place where the microphone unit is stored and which is near the main body. The terminal is further provided with a transmission-reception circuit which modulates signals outputted from the microphone unit and transmits them, and which demodulates received signals and outputs them, a loudspeaker which outputs the signals from the transmission-reception circuit as audible sounds, a detecting mechanism which detects the position of the microphone unit, and a controller which controls the input/output of sounds based on the detection signal of the detecting mechanism. The controller mutes the output signals of the microphone unit when the detecting mechanism detects that the microphone unit is at the storage place. Therefore, a muting mode can be set or canceled by moving the microphone unit. When a muting means is in a muting mode, hold tone is transmitted from the transmission-reception circuit so as to inform the caller that the line is busy.
