Description
Technical field
The utility model is related to light-controlled electronic bird.
Background technology
Existing light-controlled electronic bird is complicated, and cost is high, and the chirping of birds effect of light-controlled electronic bird is poor.
Utility model content
The purpose of this utility model is to overcome the shortcomings of that there is provided a kind of light-controlled electronic bird in existing product.
In order to achieve the above object, the utility model is achieved through the following technical solutions：
Light-controlled electronic bird of the present utility model, including resistance R1, photo resistance RG, electric capacity C1, electric capacity C2, power supply VCC,
555 time base circuit U1, buzzer B, the 555 time base circuit U1 6 pins and 2 pins all pass through electric capacity C1 connection earth signals
GND, the 555 time base circuit U1 1 pin connection earth signal GND, 6 pins of the 555 time base circuit U1 pass through photosensitive electricity
The time base circuit U1 of RG connections 555 7 pins are hindered, 7 pins of the 555 time base circuit U1 pass through base electricity during resistance R1 connections 555
Road U1 4 pins, the 8 pins connection power supply VCC of the 555 time base circuit U1,3 pins of the 555 time base circuit U1 pass through
Electric capacity C2 connection buzzers B one end, the other end connection earth signal GND of the buzzer B.
Electric capacity C1 described in the utility model is 0.01 microfarad, and the electric capacity C2 is 10 microfarads.
Resistance R1 described in the utility model is 10K ohm.
Power supply VCC described in the utility model is 6V.
The beneficial effects of the utility model are as follows：The utility model is simple in construction, cost is low, small power consumption, chirping of birds effect are good.
Brief description of the drawings
Fig. 1 is circuit theory schematic diagram of the present utility model.
Embodiment
The technical solution of the utility model is described further with reference to Figure of description：
As shown in figure 1, light-controlled electronic bird, including resistance R1, photo resistance RG, electric capacity C1, electric capacity C2, power supply VCC, 555
Time base circuit U1, buzzer B, the 555 time base circuit U1 6 pins and 2 pins all by electric capacity C1 connection earth signal GND,
The 1 pin connection earth signal GND of the 555 time base circuit U1,6 pins of the 555 time base circuit U1 pass through photo resistance RG
555 time base circuit U1 7 pins are connected, 7 pins of the 555 time base circuit U1 pass through the time base circuit U1 of resistance R1 connections 555
4 pins, the 8 pins connection power supply VCC of the 555 time base circuit U1,3 pins of the 555 time base circuit U1 pass through electric capacity
C2 connection buzzers B one end, the other end connection earth signal GND of the buzzer B.
Electric capacity C1 described in the utility model is 0.01 microfarad, and the electric capacity C2 is 10 microfarads.
Resistance R1 described in the utility model is 10K ohm.
Power supply VCC described in the utility model is 6V.
Operation principle：
As shown in figure 1,555 time base circuit U1, resistance R1, photo resistance RG, electric capacity C1 constitute non-steady-state oscillation circuit, connect
Behind energization source, circuit starting of oscillation, 555 time base circuit U1 2 pins can be alternately present high level and low level, promote buzzer B hairs
Sound, tone changes with the change of frequency of oscillation.
In use, allow photo resistance RG to be placed under light-illuminating, then with finger above photo resistance RG up and down
Rock, light intensity on photo resistance RG is projected to change, as long as being controlled with hand, buzzer B, which can just be simulated, to be sent height suddenly and neglect
Low, a variety of tweedles that change is infinite, very true to nature.
Component resistance R1 of the present utility model, photo resistance RG, electric capacity C1, electric capacity C2, power supply VCC, 555 time base circuits
U1, buzzer B, therefore component counts are few, and it is cheap, therefore the utility model is simple in construction, cost is low, small power consumption,
Chirping of birds effect is good.
It should be noted that listed above is only a kind of specific embodiment of the present utility model.Obviously, the utility model
Above example is not limited to, there can also be many deformations.In a word, one of ordinary skill in the art can disclose from the utility model
Content all deformations for directly exporting or associate, be considered as protection domain of the present utility model.
