The purpose of this utility model is in that to overcome above-mentioned deficiency to provide a kind of portable timing electronic hypnotic device easy to use.

This utility model takes techniques below measure: a kind of portable timing electronic hypnotic device, including timing circuit, oscillating circuit and electromagnetic buzzer, described timing circuit also includes time selection circuit, time selection circuit is connected in parallel on the terminating switch two ends of timing circuit, time selection circuit, by selecting switch and two capacitors to form, is linked togather with selecting switch series after two capacitor parallel connections；Timing circuit controls oscillating circuit work by time selection circuit；Described oscillating circuit produces electronic pulse signal, controls electromagnetic buzzer and produces simulated sound.

Described oscillating circuit adopts 555 integrated chips to produce narrow pulse signal, controls electromagnetic buzzer and sends the sound that drips.

The beneficial effects of the utility model are, novel in design, and simple in construction, to human body non-hazardous, utilizes electronic impulse to make electromagnetic buzzer send the sound dripped, makes people fall asleep rapidly.

Accompanying drawing explanation

Fig. 1 is the circuit diagram of a kind of embodiment of this utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in the figure, a kind of portable timing electronic hypnotic device, including timing circuit, oscillating circuit and electromagnetic buzzer, described timing circuit is by electrical switch the first transistor VT1, electrical switch transistor seconds VT2, starting switch S1, terminating switch S2, select switch S3, first capacitor C1, second capacitor C2, first resistance R1, second resistance R2 composition, be connected in series after first capacitor C1 and the second capacitor C2 parallel connection composition time selection circuit with selection switch S3, time selection circuit is connected in parallel on terminating switch S2 two ends, timing circuit controls oscillating circuit work by time selection circuit.Described oscillating circuit adopts 555 integrated chips to produce narrow pulse signal, controls electromagnetic buzzer HA and sends the sound that drips.In oscillating circuit, the 3rd resistance R3, the 4th R4 and the three capacitor C3 are timing original papers, and electromagnetic buzzer HA is the load of 555 integrated chips.

Work process of the present utility model is: after switching on power, and+9V power supply charges to the 3rd capacitor C3 through the 3rd resistance R3, the 4th resistance R4, charging interval T=0.7(R3+R4) C3, it is about 1.4 seconds.At this moment the outfan of 555 integrated chip time base circuits i.e. the 3rd foot is high potential "+9V ", and the equal no-voltage of electromagnetic buzzer HA two terminal potential does not work.The 555 integrated chip time base circuit upset when the voltage on the 3rd capacitor C3 reaches 2/3 supply voltage, on the 3rd capacitor C3, voltage is through the 4th resistance R4 and discharge end i.e. the 7th foot electric discharge, and discharge time, T1=0.7R4C3, was about 7 milliseconds.At this moment the outfan of 555 integrated chip time base circuits i.e. the 3rd foot current potential is end current potential " 0 ", and electromagnetic buzzer HA has voltage power supply to send the sound that drips.This utility model sends the rhythmical sound that drips of appropriateness by electromagnetic buzzer HA, can make that people's emotion is stable, calming nerves, makes the brain of people be in relaxation state, promotes insomniac can rapidly enter dreamland, reach the effect of hypnosis.

First press selection of time switch S3 during use and choose delay time, then starting switch S1 is clicked, + 9V power supply is activated switch S1 makes the first capacitor C1 or the second capacitor C2 moment be rushed full electricity, electrical switch transistor seconds VT2 turns on because base stage obtains forward bias by the first resistance R1, and making electrical switch the first transistor VT1 turn on by the second resistance R2 ,+9V power supply adds to oscillating circuit through electrical switch the first transistor VT1 and makes its work.Along with the first capacitor C1 or the second capacitor C2 ties slowly electric discharge through the b-e of the first resistance R1, electrical switch transistor seconds VT2, about 30 minutes or after one hour, electrical switch transistor seconds VT2 ends because losing base stage forward bias, electrical switch the first transistor VT1 ends and power cutoff immediately, makes oscillating circuit quit work.Turn off electronic hypnotic device as being intended to midway, click terminating switch S2, make the electric charge on the first capacitor C1 or the second capacitor C2 bleed off rapidly.

This utility model is not limited to above detailed description of the invention, every other embodiments drawn by those skilled in the art according to technical scheme, also belongs to protection domain of the present utility model.
