Embodiment

As shown in Figure 1, housing 1 one sides of the present utility model are provided with mouse sliding area 2, in outside dialing keyboard 3, audio frequency and headset input socket 4, audio frequency and headset accessory power outlet 5, off-hook switch 6 and loudspeaker/headset change-over switch 7 are installed.Conventional phone reception/transtation mission circuit 8 and function commutation circuit 9 are installed in the housing, one group of loudspeaker 10 and microphone 11 also are installed; Described audio frequency and headset input socket 4, audio frequency and headset accessory power outlet 5, phone reception/transtation mission circuit 8, loudspeaker 10 and microphone 11 all are linked in the function commutation circuit 9, and off-hook switch 6 and loudspeaker/headset change-over switch 7 also is connected in the function commutation circuit 9.

As shown in Figure 2 be mounted in control circuit circuit block diagram in the housing, it is made of the phone receptions/transtation mission circuit 8 of routine and the function commutation circuit 9 that is attached thereto.Function commutation circuit 9 mainly comprises an audio frequency input switching device shifter and a headset/loudspeaker switching device shifter, also comprises the computer audio frequency input circuit, headset accessory power outlet, amplifying circuit and loudspeaker and the microphone that are connected with them respectively.

Embodiment as shown in Figure 4, audio frequency input switching device shifter in the function commutation circuit mainly is made of a switch multiway change-over switch SW1 (being off-hook switch 6), and headset/loudspeaker switching device shifter mainly is made of a multiway change-over switch SW2 (being loudspeaker/headset change-over switch 7).The answer the call power supply of reception/transtation mission circuit of the pin a3 of SW1, a2 answers the call and receives the off-hook control end of transtation mission circuit, the answer the call ground of circuit of a1, the off-hook and the on-hook (referring to Fig. 3) of a1, a2, a3 tripod control phone.The voice output of computer, the microphone input, ground loop is by audio frequency and headset input socket with by diode ZD3, electric capacity E9, the computer audio frequency input circuit that E10 forms is connected on change-over switch SW1 three groups of pin b1 in addition, c1, on the d1, the sound of phone reception/transtation mission circuit receives by end (the SF signal end of Fig. 3) and inserts on the pin a2 ' of change-over switch SW2, the a1 ' of SW2 is connected on the pin b3 of SW1, the sound transmitting terminal of phone reception/transtation mission circuit (the MIC signal end of Fig. 3) is connected on the pin c3 of change-over switch SW1, ground wire is connected on the d3, pin b2, c2, d2 is connected respectively to the pin b2 ' of change-over switch SW2, c2 ', on the d2 '.

When change-over switch SW1 by last, it is on-hook that pin a1-a2 connects, pin b1-b2, c1-c2, d1-d2 connect, the computer audio frequency signal outputs on pin b2 ', c2 ', the d2 ' of change-over switch SW2.

SW1 presses when change-over switch, it is off-hook that pin a2-a3 connects, and starts telephony feature, dials, conversation etc., pin b2-b3, c2-c3, d2-d3 connect, and the then sound reception of phone, transmission, ground connection are delivered on pin b2 ', c2 ', the d2 ' of change-over switch SW2 by b2, c2, d2.
