Description
Technical field
This utility model relates to a kind of apparatus for curing insomnia, specifically a kind of portable raindrop sound apparatus for curing insomnia based on 555 timers.
Background technology
Nowadays, the rhythm of urbanization life is more and more faster, and the life stress of people increases gradually, and a lot of people has a sleepless night because of nervous work, and the method for traditional treatment insomnia is all generally the psychotherapy of Drug therapy or specialty.But Drug therapy not only has dependency but also danger very large, overeats and is in peril of one's life at any time, although and psychotherapy fundamentally treats, recurrent probability is comparatively large, and somewhat expensive.Scientific experiments proves that people easily make nerve be discharged under the rhythm sound of decaying gradually, the rhythm of the heart is steady gradually with breathing, effective hypnotic effect can be reached, the hypnotic device that market occurs mostly is musical hypnotizing device, not only complex structure, cost of manufacture is high, and power consumption is high, does not obtain popularity.
Utility model content
The purpose of this utility model is to provide a kind of portable raindrop sound apparatus for curing insomnia based on 555 timers, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
Based on a portable raindrop sound apparatus for curing insomnia for 555 timers, comprise resistance R1, chip IC 1, one end of speaker B and power supply E, described resistance R1 connects the positive pole of power supply E, a stiff end of potentiometer RP1, the pin 4 of chip IC 1 and the pin 8 of chip IC 1, the other end of resistance R1 connects the pin 6 of button K1 and chip IC 1, and the other end of button K1 connects electric capacity C1, electric capacity C2, electric capacity C4, electric capacity C4, speaker B, the pin 1 of chip IC 1 and the pin 1 of chip IC 2, another stiff end of potentiometer RP1 connects the other end of electric capacity C1, the sliding end of potentiometer RP1, the pin 2 of chip IC 1 and the pin 7 of chip IC 1, the pin 3 contact resistance R2 of chip IC 1, the pin 4 of chip IC 2 and the pin 8 of chip IC 2, the other end of resistance R2 connects a stiff end of potentiometer RP2 and the pin 7 of chip IC 2, and the sliding end of potentiometer RP2 connects the other end of electric capacity C3, another stiff end of potentiometer RP2, the pin 2 of chip IC 2 and the pin 6 of chip IC 2, the pin 3 of chip IC 2 connects electric capacity C5, and the other end of electric capacity C5 connects the other end of speaker B, and the model of described chip IC 1 and chip IC 2 is NE555.
As this utility model further scheme: described power supply E is composed in series by 2 joint 5V aneroid battery.
Compared with prior art, the beneficial effects of the utility model are: this utility model is simple based on the portable raindrop sound apparatus for curing insomnia circuit structure of 555 timers, components and parts are few, use two 555 timer chip composition intervalometers and agitators, manufacturing raindrop sound by speaker urges people to fall asleep, and the frequency of timing and raindrop sound is all adjustable, therefore there is low, the easy to adjust and portable advantage of cost of manufacture.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of the portable raindrop sound apparatus for curing insomnia based on 555 timers.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Refer to Fig. 1, a kind of portable raindrop sound apparatus for curing insomnia based on 555 timers, comprises resistance R1, chip IC 1, one end of speaker B and power supply E, described resistance R1 connects the positive pole of power supply E, a stiff end of potentiometer RP1, the pin 4 of chip IC 1 and the pin 8 of chip IC 1, the other end of resistance R1 connects the pin 6 of button K1 and chip IC 1, and the other end of button K1 connects electric capacity C1, electric capacity C2, electric capacity C4, electric capacity C4, speaker B, the pin 1 of chip IC 1 and the pin 1 of chip IC 2, another stiff end of potentiometer RP1 connects the other end of electric capacity C1, the sliding end of potentiometer RP1, the pin 2 of chip IC 1 and the pin 7 of chip IC 1, the pin 3 contact resistance R2 of chip IC 1, the pin 4 of chip IC 2 and the pin 8 of chip IC 2, the other end of resistance R2 connects a stiff end of potentiometer RP2 and the pin 7 of chip IC 2, and the sliding end of potentiometer RP2 connects the other end of electric capacity C3, another stiff end of potentiometer RP2, the pin 2 of chip IC 2 and the pin 6 of chip IC 2, the pin 3 of chip IC 2 connects electric capacity C5, and the other end of electric capacity C5 connects the other end of speaker B, and the model of described chip IC 1 and chip IC 2 is NE555.
Power supply E is composed in series by 2 joint 5V aneroid battery.
Operation principle of the present utility model is: the IC1 in circuit and the element such as potentiometer RP1, electric capacity C1 form monostable timing circuit, and button K1 is start by set date button.When needing to use, push button K1, then IC1 is set, and its 3 foot presents high level, and timing starts, timing T=1.1 (R2+RP1) C1, and its timing can regulate by potentiometer RP1 is convenient.It is electric that the high level of 3 feet of chip IC 1 makes IC2 obtain, and IC2 starts working.R2, RP2, C3 etc. form astable multivibrator, and frequency of oscillation can be regulated by RP2.This frequency of oscillation outputs to speaker B by 3 feet of IC2, sends the sound of similar raindrop, lull sb to sleep.When IC1 timing arrives, its 3 foot output low level, IC2 dead electricity, quits work, and realizes autostop.
