The utility model provides a multifunction phone which not only can use a fixed telephone line to phone a common telephone, but also can be connected with a computer to realize the shouting and the answering of a network telephone. The utility model is composed of a common telephone, a handle change-over switch, a separate audio frequency power amplifier, a horn, an on-hook switch, a USB socket used for connecting other peripherals, an audio frequency output socket and a microphone socket, wherein the USB socket, the audio frequency output socket and the microphone socket are respectively connected with a USB socket, an audio frequency output interface and a microphone interface of the computer. The functions of the common telephone and the network telephone of the telephone can be changed over through the handle change-over switch. The audio frequency power amplifier is connected with the horn, and the USB interface supplies electricity to the audio frequency power amplifier to realize network called ringing.

Description

Multi-feature telephone

Technical field: the utility model relates to a kind of telephone set of can knit a net network phone and plain old telephone, and computer and network data, audio frequency can be drawn.

Background technology: present known ordinary telephone set does not have function of network phone, can not be connected with computer and network; The network telephone of access network or computer generally adopts microprocessor and hardware voice gateways technology, and for the situation that possesses computer hardware, network telephone has repeated the partial function of computer; Do not adopt the network telephone of microprocessor and hardware voice gateways technology not dial to cry and answer plain old telephone with the normal telephone circuit.The said equipment all fail simple realization can beat plain old telephone with fixed telephone line again can be by the network network telephony feature that knits a net, and can not on equipment, computer data be drawn.

Summary of the invention: the utility model provides a kind of and can beat plain old telephone with fixed telephone line and can be connected with computer without microprocessor and hardware voice gateways again and realize the Internet telephone calls and the multi-feature telephone of answering, and computer and network data, audio frequency can be drawn by this phone.

The purpose of this utility model is achieved in that a kind of multi-feature telephone is made of ordinary telephone set, Telephone handset diverter switch, USB socket, audio frequency accessory power outlet, microphone jack, on-hook switch, audio-frequency power amplifier, loudspeaker.This phone USB socket, audio frequency accessory power outlet, microphone jack are connected with USB socket, audio output interface, the microphone interface of computer respectively.Four lines of its handle of telephone set connect the switch of a four blade double-throw, the two states of switch is defined as plain old telephone state and networking telephone state respectively, switch is under the plain old telephone state, four ports connecting with four lines of handle are connected with four lines of handle interface in the telephone set network, and all the other four lines link to each other with audio frequency accessory power outlet, the microphone jack of this phone.Audio-frequency power amplifier connects loudspeaker, is powered by USB interface; The input of audio frequency power amplifier is received the public junction of audio frequency accessory power outlet and handle diverter switch by on-hook switch.

Further specify the utility model below by drawings and Examples.

Description of drawings: Fig. 1 is each circuit connection diagram of embodiment

Fig. 2 is the circuit theory diagrams of embodiment

Embodiment: telephone handle diverter switch 2 among Fig. 1 is the plain old telephone state when the A extreme direction is connected.At this moment, telephone handle 1 four line SP1+, SP1-, MIC1-, MIC1+ are connected with end SP2+ of the same name, SP2-, MIC2-, MIC2+ on the ordinary telephone set circuit board 3.Telephone handle change over switch 2 among Fig. 1 is a networking telephone state when the B extreme direction is connected.At this moment, SP1+ has been connected to the audio output interface of the socket 6 of this phone; MIC1+ is connected to the microphone interface of this telephone socket 6 through on-hook switch 5; MIC1-and SP1-are connected to the common signal earth terminal of socket 6.On-hook switch 5 among Fig. 1 is a hook state when the D end position is connected, and this moment, MIC1+ was cut off with being connected of microphone interface, and the audio output interface of the signal input part of audio frequency power amplifier 4 and socket 6 is switched on; When the C end position is connected is off hook state, and the audio output interface of the signal input part of audio frequency power amplifier 4 and socket 6 is cut off.The power end VCC of the power end gang socket 6 of audio frequency power amplifier 4, the output of audio frequency power amplifier 4 is connected with loudspeaker.The audio frequency accessory power outlet of Fig. 1 socket 6, microphone jack are connected with audio output interface, microphone interface in the sound card 7 respectively, and the USB socket in Fig. 1 socket 6 is connected with computer 8USB interface.

JK1, JK2, JK3 are respectively audio frequency accessory power outlet, microphone jack, the USB socket that this phone is used to connect other peripheral hardwares among Fig. 2.USB socket connects VCC, DATA-, DATA+, the GND end of computer USB interface, and the audio frequency accessory power outlet connects ROUT, LOUT, the GND end of sound card audio output interface, and microphone jack connects GND, the MICIN end of sound card microphone interface.

Mainly constitute the handle diverter switch among Fig. 2 by button switch K 1, button switch K 2, integrated circuit (IC) 1, transistor Q1, relay J 1, relay J 2, IC1 is a rest-set flip-flop, when K1 presses, the S0 end high level of IC1 makes Q0 end output high level, electric current makes transistor Q1 conducting by R3, and relay J 1, relay J 2 are networking telephone state by adhesive all at this moment.Telephone handle SP1+, SP1-among Fig. 2, MIC1+, MIC1-are connected to JK1, JK2 by relay J 1, relay J 2, when K2 presses, the R0 end high level of IC1 causes Q0 end output low level, transistor Q1 loses bias voltage and ends, relay J 1, relay J 2 discharge, and SP1+, SP1-, MIC1+, MIC1-are connected to SP2+, SP2-, MIC2+, the MIC2-of telephone set by relay J 1, relay J 2.Therefore this control circuit power supply is supplied with by computer USB interface, and to be in release condition be not the plain old telephone state for relay J 1, relay J 2 when not connecing computer, can normally beat plain old telephone.

Transistor Q2, light-emitting diode D2, light-emitting diode D3 constitute handle diverter switch condition indication circuit among Fig. 2.Light-emitting diode D3 is luminous during the plain old telephone state; Transistor Q2 base stage obtains bias voltage and conducting by resistance R 4 during networking telephone state, and light-emitting diode D2 is luminous.

K switch 3, integrated circuit (IC) 2, transistor Q3 form on-hook switch among Fig. 2.K3 is independent on-hook switch, is not connected with ordinary telephone set, and closure when handle puts down on-hook disconnects during off-hook; IC2 is an analog switching ic, and three groups of switches are wherein arranged, and is on-hook when the A end is with C end high level among the IC2, and corresponding X end is communicated with the X1 end, and the Z end disconnects with the Z0 end; Transistor Q3 loses bias voltage and ends when being in networking telephone state, and the IC2B end is low level, and the Y end disconnects with the Y0 end; Transistor Q3 is saturated during the plain old telephone state, the IC2B end is high level, the Y end is logical with the Y0 termination, both made off-hook make a phone call this moment, come the bell signal of automatic network also can hold 7 ends that be input to integrated circuit (IC) 3 with Y0 by the Y end, IC3, C5, C6, C7, C8, R11, R12 constitute audio frequency power amplifier, and 1 end of IC3,3 ends connect loudspeaker V1 and realize the network phone calls ring.
