Brief description of the drawings
The present invention is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
Embodiment
Shown in Fig. 1：Voicefrequency circuit IC1 P9 ends and electric capacity C1 one end, electric capacity C3 one end, electric capacity C4 one end, by
Words device MIC 4 ends are connected, and the electric capacity C1 other end is connected and is grounded with the other end of the electric capacity C3 other end, electric capacity C4, called
Device MIC 1 end is connected with analog switch IC3 one end, the analog switch IC3 other end and analog switch IC5 one end, voltage stabilizing
Pipe DZNegative pole, electric capacity C6 one end, electric capacity C5 one end, electric capacity C2 one end be connected, electric capacity the C2 other end and audio-frequency electric
Road IC1 T9 ends are connected, voltage-stabiliser tube DZPositive pole be connected and be grounded with the electric capacity C6 other end, the electric capacity C5 other end, simulate
Switch the IC5 other end and the U in sinusoidal generation circuit IC2outEnd is connected, one end of the R7 in sinusoidal generation circuit IC2 and mould
Intend switch IC5 control terminal, resistance R1 one end, NAND gate circuit IC4 input, one end of send button are connected, and non-
Gate circuit IC4 output end is connected with analog switch IC3 control terminal, resistance R1 other end ground connection, send button it is another
End is connected with resistance R2 one end, resistance R3 one end, resistance R2 other end ground connection, resistance the R3 other end and power supply+Vcc
It is connected.
The operation principle of the present invention is as follows：Sinusoidal generation circuit IC2 produces the howling of 18K hertz, and voicefrequency circuit IC1 leads to
Cross T9 ends to handle audio signal, voicefrequency circuit IC1 provides power supply, electric capacity C1, electric capacity by P9 ends to receiver MIC
C3, electric capacity C4 are power filtering capacitor, and electric capacity C5, electric capacity C6 are signal filter capacitor, and electric capacity C2 is signal coupled capacitor, voltage stabilizing
Pipe DZClamping action is played, reasonable selection resistance R2 and resistance R3 size, makes send button and resistance R2, resistance R3 tie point
Level be high level.
When send button does not close, because R1 one end is grounded, therefore sinusoidal generation circuit IC2 does not work, simulation
Switch IC5 is not turned on, and NAND gate circuit IC4 inputs are low level, and NAND gate circuit IC4 exports high level, therefore simulation is opened
IC3 conductings are closed, the sound of people is changed into analog electrical signal from receiver MIC, voicefrequency circuit IC1 T9 ends are coupled to through electric capacity C2.
Power amplification and A/D conversions are completed in voicefrequency circuit IC1, audio digital signals is formed, baseband signal is re-formed, through radio frequency electrical
Electromagnetic wave is coupled into by antenna after the processing of road, to Base Transmitter, so as to complete normally to converse.
During mobile phone use, when the phone for finding to be connected to is harassing and wrecking or fraudulent call, cellie presses immediately
Send button.Now, NAND gate circuit IC4 input is changed into high level, and its output is changed into low level, makes analog switch
IC3 control terminal is low level, and analog switch IC3 disconnects.The high level come simultaneously through send button transmission is applied to sinusoidal production
One end of resistance R7 in raw IC circuit 2, makes sinusoidal generation circuit IC2 work, and the sine wave of uttering long and high-pitched sounds of 18K hertz is produced, by just
String generation circuit IC2 UoutEnd output.Because analog switch IC5 control terminal is changed into high level, analog switch IC5 is turned on, just
String generation circuit IC2 UoutHold the T9 that is coupled to voicefrequency circuit IC1 of the acoustical signal through electric capacity C2 that utter long and high-pitched sounds of the 18K hertz of output
End, power amplification and A/D conversions are completed in voicefrequency circuit IC1, audio digital signals is formed, baseband signal is re-formed, through penetrating
Electromagnetic wave is coupled into by antenna after frequency circuit processing, to Base Transmitter, harassing and wrecking person or swindler is received whistler, so as to feel
To discomfort.
So, by using sinusoidal generation circuit, voicefrequency circuit, receiver and send button, harassing and wrecking person or swindler are made
Do not feel well, so as to reduce or terminate harassing and wrecking and swindle.
During implementation, voicefrequency circuit IC1, electric capacity C1, electric capacity C2, electric capacity C3, electric capacity C4, electric capacity C5, electric capacity C6, voltage-stabiliser tube DZ
