(4), machine shell panel is provided with supply socket, recorder power socket, power supply indicator mains switch, record button, playback button, loudspeaker, recording playback sound indicator light, microphone and voice output socket.
The utility model and magnetic tape type recorder, telephone set constitute an integral body, and phone inlet wire of the present utility model and telephone set inlet wire also connect, and the power line of recorder links to each other with the voice output socket with the recorder power socket respectively with line input.Press mains switch, power supply indicator is bright.Press record button, the indication recording beginning of recording playback sound indicator light, owner can message typing the utility model with oneself in; For test effect, it is bright to press this indicator light of playback button, and owner can hear the message of oneself.At this moment, press the recorder record button, can go out.Ring connect as if nobody after 7 seconds, the RP of speech processor and the output simultaneously of CON end are high, triode Q2 drives relay J 1 work, the utility model begins to play owner's message, " ticking " sound pin output one " ticking " sound of speech processor notifies the other side to begin recording, simultaneously after owner's message finishes, PR holds step-down, NAND gate M exports high, and is high with door F output, light activated power thyristor work, the tape recorder power connection, begin recording, after 30 seconds, CON holds step-down, End of Tape is waited for next ring.After owner returns, promptly know phone information when going out by playback.The utlity model has simple in structure, the reliability height, the characteristics that cost is low can be used with existing various tape recorders, can the unit of being widely used in and the subscriber's extension station of family on.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the utility model machine shell panel schematic diagram;
Fig. 2 is the utility model telephone circuit, the tinkle of bells receiving circuit part line map;
Fig. 3 is the utility model speech processing circuit, tape recorder power driving circuit, power circuit partial line road figure.
The utility model is described in further detail below in conjunction with accompanying drawing: as Fig. 1, Fig. 2, shown in Figure 3, speech processing circuit is made of speech processor IC1, dynamic memory IC2, IC3, operational amplifier IC4, IC5, IC6, power amplifier IC7, microphone 10, loudspeaker 8 and respective peripheral circuit, wherein, IC4, IC5, IC6 are three operational amplifiers in the four-operational amplifier.When owner records, by microphone 10(M1C) import by the AUI end of speech processor IC1 through the voice signal of operational amplifier IC4 amplification, after internal mode/number conversion is handled, deliver to dynamic memory IC2, IC3 storage.During playback, the voice digital signal that speech processor will be stored among dynamic memory IC2, the IC3 takes out through inner D/A switch, by being exported by the AUO end, after operational amplifier IC5, IC6 amplification, through 1,2 pin of power amplifier IC7, relay J 2-1, deliver to loudspeaker 8 and send voice.
Telephone circuit is made of bridge rectifier T1, triode Q1, Q2 and respective peripheral circuit thereof, and the base stage of triode Q2 links to each other with the CON end of speech processor IC1 by resistance R 6, is connected to relay J 1 between collector electrode and the power Vcc.Bridge rectifier T1 offers triode Q1 to determine the direct voltage of polarity, after the CON of speech processor IC1 end is for height, triode Q2 drives relay J 1 adhesive, 2,3 pin of J1-1, J1-2 are connected, and the output of telephone line and sound circuit is all connected with the amplifying circuit that triode Q1 forms.Owner's signal of leaving a message amplifies after capacitor C 2 is coupled to triode Q1 base stage, delivers to telephone line.The other side guest's voice signal is then delivered to voice output socket 11(JP1 through resistance R 4, R5, R3, capacitor C 3 couplings), by tape recorder typing the other side's message.Suitably select the resistance of R4, R5, R3, make that current potential has the function of the side sound that disappears relatively from the signal stabilization of capacitor C 2 between resistance R 4, the R5.
