Apparatus for hands-free operation of a mobile telephone unit in a car
First Claim
1. An apparatus for permitting hands-free operation of a mobile telephone unit in a car, comprising:
- a wireless microphone transmitter, to be disposed in a passenger room of the car, for generating wireless outgoing signals corresponding to sounds picked up in the passenger room; and
a main terminal including;
a terminal housing to be disposed in the passenger room, said terminal housing confining a receiving space and having one end adapted to be inserted into a cigarette lighter socket of the car;
a circuit board mounted in said receiving space;
a receiver circuit mounted on said circuit board and capable of receiving said wireless outgoing signals from said transmitter;
a connector unit including an electrical cable having one end connected electrically to said receiver circuit and an opposite end extending out of said terminal housing, and a telephone connector connected electrically to said opposite end of said electrical cable and adapted to be connected electrically to the mobile telephone unit to enable the mobile telephone unit to receive said wireless outgoing signals from said receiver circuit and transmit wirelessly said wireless outgoing signals;
a loudspeaker mounted on said circuit board and connected electrically to said one end of said electrical cable, wireless incoming signals received by the mobile telephone unit being received by said loudspeaker via said electrical cable, said loudspeaker generating an acoustic output corresponding to the wireless incoming signals; and
a set of electrical contacts provided on said one end of said terminal housing and connected electrically to said receiver circuit and said loudspeaker, said electrical contacts being adapted to connect electrically said receiver circuit and said loudspeaker to a car battery of the car via the cigarette lighter socket so as to permit supply of electric power to said receiver circuit and said loudspeaker.

Abstract
An apparatus for permitting hands-free operation of a mobile telephone unit in a car includes a wireless microphone transmitter for generating wireless outgoing signals corresponding to sounds picked up in the passenger room of a car, and a main terminal which has a terminal housing with one end adapted to be inserted into a cigarette lighter socket of the car. A receiver circuit is disposed in the terminal housing and is capable of receiving the wireless outgoing signals from the transmitter. A telephone connector is adapted to be connected electrically to the mobile telephone unit and enables the mobile telephone unit to receive the wireless outgoing signals from the receiver circuit and transmit wirelessly the wireless outgoing signals. Wireless incoming signals received by the mobile telephone unit are received by a loudspeaker in the terminal housing. The loudspeaker generates an acoustic output corresponding to the wireless incoming signals. A set of electrical contacts on the one end of the terminal housing connects electrically the receiver circuit and the loudspeaker to a car battery of the car via the cigarette lighter socket.
