Embodiment
A kind of vibrating sensing warning device, it is characterized in that: comprise piezoelectric buzzer Y1, buzzing sheet Y2, d type flip flop, K switch W1, music IC chip, resistance R 1-R3, R5-R9, capacitor C 3-C9, diode D3-D4, triode Q1-Q3, inductance L 1, LED, power supply VCC, boost inductance L1, described power supply VCC passes through capacitor C 4 and the C5 ground connection for the parallel connection of filtering and voltage stabilizing, power supply VCC connects the K2 pin of K switch W1 by LED, the K1 pin ground connection of K switch W1, the K pin of K switch W1 connects d type flip flop D pin, the K pin of K switch W1 meets the reset terminal pin R of d type flip flop by electric capacity, the R pin of d type flip flop is by resistance R 9 ground connection, be connected piezoelectric buzzer Y1 between the base stage of described triode Q2 and emitter, the base stage of described triode Q2 meets power supply VCC by R1, R1 provides base current for triode Q2, the emitter of described triode Q2 is connected with for the resistance R 6 of stablizing triode Q2 quiescent point, the CLK pin that the emitter of triode Q2 connects d type flip flop provides clock for it, the Q pin of described d type flip flop connects the Music Clip input end by resistance R 2, described Music Clip output terminal connects the base stage of triode Q3 by resistance R 3, the collector of triode Q3 links to each other with the collector of the Q1 of triode, the base stage of the emitter connecting triode Q1 of triode Q3, the grounded emitter of triode Q1, the collector of triode Q3 connects boost inductance and drives boost inductance work, and described boost inductance is connected with buzzing sheet Y2 and accessed short circuit both positive and negative polarity, the Q pin contact resistance R8 of described d type flip flop, resistance R 8 is by capacitor C 9 ground connection, capacitor C 9 connects the R pin of d type flip flop by diode D4, the anode of diode D connects electric capacity, and negative electrode connects d type flip flop R pin.
The power supply of this circuit is directly convenient mobile with the 9V powered battery, and the governor circuit of this alarm uses a cheap piezoelectric buzzer Y1 as sensor.This hummer has the Bidirectional pressure electrical effect: when adding voltage at its two ends, its piezoceramic material can produce mechanically deform and send vibrations sound; Otherwise, when it is subject to the robber and forces open the door the mechanical shock sound that produces when entering the room, will produce corresponding output voltage at its two ends.Here a specific character after utilizing makes it play the effect of vibration sensor.The generation part of reporting to the police then is the last specific character of usefulness.The voltage that piezoelectric sensor Y1 produces amplifies approximately 200 times by the first order amplifier that transistor Q2 etc. forms.Its collector voltage is high level when not triggering.R1, R2 provide the effect of Q2 bias voltage.K switch W1 plugged, because the electric capacity both end voltage can not be suddenlyd change, 10 pin of CD4013 are high level, and slowly charge through resistance R 9, play the purpose of start delayed alarm, when capacitor charging is reduced to the 3.6V left and right sides to 10 pin level, alarm enters the state of alert, in case enough strong vibration signal is arranged, detect through sensor Y1, and through the Q2 amplification, the negative saltus step of output triggers the 13 pin output high level that trigger makes CD4013, triggers Music Clip work, Music Clip powers on just (generally to be had 110 by 2 pin output audio signals, 119,120 by 3 foot control systems: unsettled 110, connect positive 119, connect negative 120), then by Q4, the Darlington transistor that Q3 forms drives boost inductance driving buzzing sheet and sounds the alarm.At this moment the high level that triggers slowly charges to capacitor C 9 through resistance R 8, and through 10 pin of diode D4 to CD4013, level constantly raises, and 13 pin of CD4013 keep high level constant in charging process, until charging voltage arrives about 2V, make the 13 pin upset of CD4013 be low level, the voltage of C9 discharges rapidly by diode D3 and resistance R 7, and 10 pin of CD4013 are reduced to low level, circuit reenters the state of alert, receives next time to trigger.And the power consumption of this circuit only has several milliamperes.
