Compared with prior art, this utility model use faradism pole piece A, time basis set become chip NE555 and the integrated chip of voice
The mode that NFC5212 combines, when without human or animal close to faradism pole piece A, the now grid of technotron VF
Voltage stabilization, the resistance between drain electrode and the source electrode of technotron VF is less, and therefore electric current is relatively big, and then time basis set become
The current potential of the pin 2 of chip NE555 is in high potential so that time basis set become pin 3 output low level of chip NE555,
So that the pin 2 of voice integrated chip NFC5212 is in low level, now voice integrated chip NFC5212 does not works,
Then speaker BL will not send the sound.When there being human or animal close to faradism pole piece A, the induced signal of human body can make junction type
The grid voltage change of field effect transistor VF, causes the resistance value between drain electrode and the source electrode of technotron VF to increase, makes
Time basis set become the pin 2 of chip NE555 to be in electronegative potential, this circuit upset in basis set becomes chip NE555 constantly, Shi Ji
The level of pin 3 output of integrated chip NE555 is become high level from low level, and then makes voice integrated chip NFC5212
Pin 2 be in high level, now voice integrated chip NFC5212 is triggered and is worked, voice integrated chip NFC5212
Pin 4 output voice signal through audio-frequency amplifier tube V amplify after, send voice message by speaker BL.Regulation current potential
Actuator RP1 and the resistance of potential regulator RP2, thus it is possible to vary the sensitivity of circuit, so regulation have human or animal close
The scope that faradism pole piece A is sensed；Can people or house pet near time, send voice reminder, thus remind child not lean on
Near and drive the close of house pet.
Accompanying drawing explanation
Fig. 1 is circuit diagram of the present utility model.
Detailed description of the invention
The utility model is described in further detail below.
As it is shown in figure 1, this utility model includes faradism pole piece A, technotron VF, resistance R1, resistance R2, electricity
Position actuator RP1, potential regulator RP2, speaker BL, time basis set become chip NE555, voice integrated chip NFC5212,
DC source GB, electric capacity C and audio-frequency amplifier tube V, the grid of faradism pole piece A and technotron VF is connected, junction type
The drain electrode of field effect transistor VF by resistance R1 with time basis set become chip NE555 pin 4, time basis set become the pipe of chip NE555
One end of foot 8, one end of resistance R2, one end of speaker BL and power supply GB connects；The source electrode of technotron VF with
Time basis set become one end of the pin 2 of chip NE555 and potential regulator RP1 to connect, the other end of potential regulator RP1 with
The current potential adjustable side of potential regulator RP1, time basis set become the pin 1 of chip NE555, one end of electric capacity C, the integrated core of voice
The other end of the pin 1 of sheet NFC5212, the emitter stage of audio-frequency amplifier tube V and power supply GB connects；The other end of electric capacity C with
Time basis set become the pin 5 of chip NE555 to connect, time basis set become the pin 3 of chip NE555 and the one of potential regulator RP2
End connects, the other end of potential regulator RP2 and the current potential adjustable side of potential regulator RP2 and voice integrated chip NFC5212
