Abstract

A portable communication and audio system includes a radio telephone for receiving a first audio signal and transmitting a corresponding first radio signal through a transmitter to another location, and for receving a second radio signal through a receiver and converting it to a second audio signal. An audio device (68) provides a third audio signal. A microphone (16) receives the first audio signal. A headset (10) with first (18) and second (20) speakers is provided for selectively listening to the second or the third audio signal. A user-operated switch selectively disables the first speaker in a first state or the microphone in a second state. A state-indicating apparatus produces a signal indicating the state of the user-operated switch (12). The system preferably includes a pivotable boom (14) depending from the headset, with the microphone being located on the boom. The audio device can be separated from the radio telephone. The system preferable includes a momentary, user-controlled switch and control apparatus for implementing a control function for a selected one of the radio telephone and the audio devices.
