Patent ID: 6882871

Claim:
A transfer connection device for wirelessly connecting a mobile phone and a hand-free handset, comprising: a first connector coupling with the mobile phone; and a second connector coupling with the hand-free handset for transmitting signals between the mobile phone and the hand-free handset through the first connector and the second connector in a wireless fashion, wherein the first connector includes a first radio transmitting and receiving unit, a first antenna, a first modulation/demodulation unit, a first control unit, a first memory unit, a first processing unit, and a first connection interface; wherein the first radio transmitting and receiving unit is controlled by the first control unit for receiving radio signals from the second connector and for emitting signals output by the first modulation/demodulation unit through the first antenna to the second connector; the first antenna receives and transmits radio signals; the first modulation/demodulation unit is controlled by the first control unit to modulate output signals from the first processing unit and transfer to the first radio transmitting and receiving unit, and to demodulate radio signals received from the first radio transmitting and receiving unit and transfer to the first processing unit for processing; the first control unit controls and coordinates all other units in the first connector; the first memory unit stores set values of the first connector and temporarily stores the received and transmitted radio signals; the first processing unit is controlled by the first control unit for processing audio voice and control data of the mobile phone and providing to the first modulation/demodulation unit; and the first connection interface allows a signal terminal of the mobile phone connecting the first connector, and is selectively a signal line or a socket.
