| 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 receiving a second radio signal through a receiver and converting it to a second audio signal. An audio device provides a third audio signal. A microphone receives the first audio signal. A headset with first and second 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. A control apparatus, responsive to the state-indicating apparatus, enables telephone usage by connecting the microphone to the transmitter and connecting the second speaker to the receiver when the user-operated switch is in the first state, and connects the first and second speakers to receive the third audio signal when the user-operated switch is in the second state. The system preferably includes a pivotable boom depending from the headset, with the microphone being located on the boom. The audio device can be separate from the radio telephone. The system preferably 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 device.

What is claimed is:
1. A portable communication and audio system comprising:
- (a) a radio telephone for receiving a first audio signal and transmitting a corresponding first radio signal through a transmitter to another location and for receiving a second radio signal through a receiver and converting it to a second audio signal;
- (b) an audio device providing a third stereophonic audio signal;
- (c) a microphone receptive of said first audio signal and being enabled through a conductive path that includes a link for said microphone;
- (d) a headset with first and second speakers for selectively listening to said second audio signal through said second speaker when conduction through said link for said microphone is enabled, or said third stereophonic audio signal through said first and second speakers when a required conductive link for said second speaker is enabled;
- (e) a user-operated switch having at least two states including a first state for enabling conduction through said conductive link for said second speaker and a second state for enabling conduction through said link for said microphone;
- (f) a state-indicating means for detecting the state of said user-operated switch; and
- (g) a control means, responsive to said state-indicating means for connecting said first and second speakers to receive said third stereophonic audio signal when said user-operated switch is in said first state, and for enabling telephone usage by connecting said microphone to said transmitter and connecting said second speaker to said receiver when said user-operated switch is in said second state.
