Telephone with handsfree function
Abstract:
An exemplary embodiment of a telephone with handsfree function includes a telephone set and a handset. Two metal pieces are fixed in the handset, and two electromagnetic valves are fixed in the telephone set. A processing circuit in the telephone set powers on the electromagnetic valves when the handsfree function of the telephone is enabled to generate an electromagnetic field. The electromagnetic valves magnetically attract the metal pieces, such that the handset is firmly held on the telephone set.
