| Abstract: |
A headset includes a base connected to a wireless telephone, a clip connected to the base, a microphone connected to the base, and an earplug connected to the base. A headset wire connects to the base and to the telephone. The headset wire is releasable from the base. A rotatable microphone stem connects the base and the microphone. A rotatable speaker stem connects the base and the speaker. A switch on the base opens and closes a circuit in the telephone. A speaker gear in the base connects to said speaker stem. A speaker gear in the base connects to the speaker stem, the speaker gear connects to the microphone gear. A cogwheel intermeshes between the speaker gear and the microphone gear. The microphone gear and the speaker gear are sized so that said speaker is moved to a deployed position when said microphone is moved to a deployed position and said speaker is moved to a retracted position when said microphone is moved to a retracted position. A switch in the base opens and closes a circuit in the telephone; the switch opens the circuit when the microphone and the speaker are in the deployed position, and the switch closes the circuit when the microphone and the speaker are in the retracted position. The clip attaches to a stem of a pair of eyeglasses worn by a caller.
