Description
Technical field
The utility model relates to a kind of circuit, specifically a kind of birthday cake acousto-optic automatic control circuit.
Background technology
Birthday cake has been widely used in modern people's birthday party, in order to set off happy atmosphere by contrast, existing cake function singleness can not meet people's demand, although there has been the music cake that music is combined with cake now, but the unlatching of music need to manually be opened, due to when some candle, generally can be by dimmed light around, can make like this to reach reasonable effect after candle combustion, like this in order music to be sounded after a candle, just need to manually open, not only trouble but also because light more likely can misoperation, cannot smooth opening music.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of birthday cake acousto-optic automatic control circuit, can be when lighted candle, send automatically musical sound and glisten simultaneously.
To achieve these goals, the technical solution adopted in the utility model is: a kind of birthday cake acousto-optic automatic control circuit, comprise direct supply G, switch S, potentiometer RP1, potentiometer RP2, photodiode VDL, capacitor C 1, electrochemical capacitor C2, resistance R, light emitting diode VTL, hummer B, 555 o'clock base integrated chips and music ic KD9310, the positive pole of direct supply G is connected with one end of switch S, one end of the other end of switch S and potentiometer RP1, the R port of 555 o'clock base integrated chips, the VCC port of 555 o'clock base integrated chips is connected with a stiff end of potentiometer RP2, another stiff end of potentiometer RP1 is connected with the TR port of 555 o'clock base integrated chips and the negative electrode of photodiode VDL respectively, another stiff end of potentiometer RP2 is connected with the D port of 555 o'clock base integrated chips and is connected with the TH port of 555 o'clock base integrated chips and the positive pole of electrochemical capacitor C2 respectively by resistance R, the GND port of the anode of the negative pole of direct supply G and photodiode VDL, one end of capacitor C 1,555 o'clock base integrated chips, the negative pole of electrochemical capacitor C2, anode, hummer B and the music ic KD9310 of light emitting diode VTL are connected, the other end of capacitor C 1 is connected with the CO port of 555 o'clock base integrated chips, the negative pole of light emitting diode VTL is connected with music ic KD9310, and music ic KD9310 is connected with the OUT port of 555 o'clock base integrated chips.
The beneficial effects of the utility model are: simple in structure, easy to use, and when lighted candle, by music ic KD9310, drive hummer B to sound, control light emitting diode VTL simultaneously and glisten, without just manually opening, can automatically control.
Accompanying drawing explanation
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises direct supply G, switch S, potentiometer RP1, potentiometer RP2, photodiode VDL, capacitor C 1, electrochemical capacitor C2, resistance R, light emitting diode VTL, hummer B, 555 o'clock base integrated chips and music ic KD9310, the positive pole of direct supply G is connected with one end of switch S, one end of the other end of switch S and potentiometer RP1, the R port of 555 o'clock base integrated chips, the VCC port of 555 o'clock base integrated chips is connected with a stiff end of potentiometer RP2, another stiff end of potentiometer RP1 is connected with the TR port of 555 o'clock base integrated chips and the negative electrode of photodiode VDL respectively, another stiff end of potentiometer RP2 is connected with the D port of 555 o'clock base integrated chips and is connected with the TH port of 555 o'clock base integrated chips and the positive pole of electrochemical capacitor C2 respectively by resistance R, the GND port of the anode of the negative pole of direct supply G and photodiode VDL, one end of capacitor C 1,555 o'clock base integrated chips, the negative pole of electrochemical capacitor C2, anode, hummer B and the music ic KD9310 of light emitting diode VTL are connected, the other end of capacitor C 1 is connected with the CO port of 555 o'clock base integrated chips, the negative pole of light emitting diode VTL is connected with music ic KD9310, and music ic KD9310 is connected with the OUT port of 555 o'clock base integrated chips.
The course of work: base integrated chip formed light-operated monostable circuit with photodiode VDL and peripheral component thereof in 555 o'clock, under ordinary ray radiation situation, photodiode VDL internal resistance is larger, the TR port of 555 o'clock base integrated chips is inputted in high level, therefore, the OUT port of 555 o'clock base integrated chips is low level output, thereby makes music ic KD9310 can not get voltage, and then cannot drive hummer B, therefore do not sound.
When light on cake candle time, light strengthens suddenly, photodiode VDL internal resistance is reduced, the TR port of now 555 o'clock base integrated chips is inputted in low level, the OUT port of 555 o'clock base integrated chips is high level output, be added to the power end of music ic KD9310, thereby make the music signal of music ic KD9310 output drive hummer B sounding; Make light emitting diode VTL conducting simultaneously, carry out flashing.
