Abstract

A cell phone-hand set combination unit making it possible to operate a cell phone in the manner of a hand set. The unit includes a hand set provided with a mouthpiece having a microphone therein, an earpiece having a miniature loudspeaker therein, and a yoke bridging the mouthpiece and the earpiece, said yoke having a socket therein adapted to cradle a cell phone. The unit also includes a cell phone provided with a microwave transceiver to which is coupled a microphone and an ear phone; and an interface network housed in the yoke and operative when the cell phone is cradled in the socket to couple the cell phone to the hand set so that the microphone and earphone of the cell phone are supplanted by the microphone and speaker of the hand set which then functions like a cordless hand set.

Claims

1. A cell phone-hand set combination unit comprising:

A. a hand set provided with a mouthpiece having a microphone therein, an earpiece having a miniature loudspeaker therein, and a yoke bridging the mouthpiece and the earpiece, said yoke having a socket therein adapted to cradle a cell phone;

B. a cell phone provided with a microwave transceiver to which is coupled a microphone and an ear phone; and

C. an interface network housed in the yoke and operative when the cell phone is cradled in the socket to couple the cell phone to the hand set so that the microphone and earphone of the cell phone are supplanted by the microphone and speaker of the hand set which then functions like a cordless hand set.

2. A combination unit as set forth in claim 1 in which the cell phone includes a key pad for dialing.

3. A unit as set forth in claim 1 in which the cell phone is a Generation III phone and includes a video screen.

4. A combination unit as set forth in claim 1, further including switching means governing the operation of the network to render the network active only when the cell phone is cradled in said socket.

5. A combination unit as set forth in claim 4, in which the switching means includes a magnetically-actuated switch in the yoke underlying the socket and a magnet in the cell phone which is adjacent the switch when the cell phone is cradled.

6. A combination unit as set forth in claim 1, in which the cell phone is provided with a jack whose contacts are connected to the microphone and ear phone of the cell phone, and the hand set is provided with a plug connected to the network whereby when the plug is plugged into the jack, the microphone and earphone of the cell phone are then supplanted by the microphone and speaker of the hand set.

7. A unit as set forth in claim 1 in which an amplifier is housed in the yoke to amplify signals fed to the speaker of the hand set.

8. A unit as set forth in claim 7 in which the amplifier and the interface network are formed by IC chips.

9. A combined unit as set forth in claim 1 associated with a speaker phone unit having a microphone and loudspeaker.

10. A combined unit as set fort in claim 9 including circuit means which operate when the combined unit is coupled to the speaker phone unit to supplant the microphone and speaker of the combined unit with the microphone and speaker of the speaker phone.
