ABSTRACT:
A hands-free adapter for a telephone is disclosed. The hands-free adapter includes a housing, a speaker and a microphone that may be electrically coupled to a telephone. The hands-free adapter couples to a cigarette lighter receptacle of a vehicle. This provides power to operate the speaker and the microphone. In addition, power is coupled to the telephone for operating the telephone and charging the telephones batteries. The hands-free adapter also includes an articulating cable for positioning the speaker and the microphone near a user. The microphone is disposed within a boom which is pivotally coupled to the housing such that the boom may be moved from a retracted position to a fully extended position. The microphone is automatically activated as it is moved out of the retracted position and is automatically deactivated as it is moved back into the retracted position.
