Abstract

A cellular telephone system, including a cellular telephone transceiver unit, an ear piece which receives the voice vibrations of a user, and a wireless linkage operatively connecting the ear piece to the cellular telephone transceiver unit, allows a user to be in a hands-free mode when using a cellular telephone. The cellular telephone transceiver unit includes a personal digital assistant and a pager with a vibration module. The ear piece generally uses a bone sensor along with an air sensor placed in the external auditory canal of the user to detect the voice vibrations of the user. Further, a speaker is included in the ear piece to allow the user to hear incoming data from the cellular telephone transceiver. The wireless linkage uses low power radio frequency waves to send and receive signals between the ear piece and the cellular telephone transceiver unit. Both the ear piece and the cellular telephone transceiver unit require power which is supplied by batteries. Both the ear piece and the cellular telephone transceiver may be recharged by simply placing them in a docking station.

Claims

1. A telephone comprising:

a cellular telephone handset having a first piece and a second piece;

a voice transceiver disposed within the cellular telephone handset;

a hinge operatively connecting the first piece and the second piece;

a portion of the cellular telephone handset movable in an accurate path to allow the telephone to transition from a closed position to an open position;

an external display to permit a user to view information on the external display without opening the telephone;

an external display image associated with the external display, the external display image having a top portion and a bottom portion and being orientated such that the top portion is nearer the hinge than the bottom portion, wherein the external display is used to display information about an incoming call when the telephone is in a closed position;

an internal display permitting the user to view information when the telephone is in the open position;

an internal display image associated with the internal display, the internal display image having a top portion and a bottom portion and being oriented such that the bottom portion is nearer the hinge than the top portion when the telephone is in the open position;

touch-operable inputs usable when the telephone is in the open position, the touch operable inputs used to control the telephone;

a first short range transceiver disposed within the cellular telephone allowing wireless communication with a remote earpiece, the first short range transceiver transmitting voice signals between the telephone and a second short range transceiver located in said remote earpiece using low powered digital RF signals;

a microphone in said remote earpiece, said microphone electrically coupled to a digital signal processor, wherein said digital signal processor contains a bandpass filter, said bandpass filter rejecting frequencies outside normal speech frequencies;

said second short range transceiver transmitting voice signals between said remote earpiece and said cellular telephone.
