ABSTRACT:
A portable hold-free device is set forth for a hand phone, including an interface board and an external wire set. The interface board is sandwiched between a hand phone and a battery. A hold-free circuit set is contained in the interface board and connected to the external wire set. The external wire set includes an earphone and a microphone. The hold-free device enables the hand phone to be used without being held during driving a car, riding a motorcycle or a bicycle, walking or in other conditions in which the user is inconvenient to hold the hand phone. A speech memory IC is added to the interface board to serve as an answering machine.
