Wherein：1- audio signal input, 2- silicon full-bridge, 3- is silicon-controlled, 4- motor, 5- triode.
Specific embodiment
The utility model is described in detail below in conjunction with attached drawing and specific embodiment, herein showing with the utility model
The utility model is described in detail below in conjunction with attached drawing and specific embodiment in meaning, herein with the schematic reality of the utility model
It applies example and explanation is used to explain the utility model, but be not intended to limit the scope of the present invention.
As shown in Figure 1 to Figure 2, a kind of water spray control circuit, including audio signal input 1, adjustable voltage control electricity
Road, motor 4 and water pump, adjustable voltage control circuit include silicon full-bridge 2 and silicon-controlled 3, silicon full-bridge 2 and audio signal input
1 connection, 1 signal of audio signal input directly control the size of silicon-controlled 3 angle of flow after silicon full-bridge 2, make controllable
The conducting of silicon 3 changes conducting according to the amplitude of music, loads the electricity exported for direct current generator 4, water pump, water pump with silicon-controlled 3
It flows size and rotates, to control the water yield of water pump.
The circuit is the direct current that audio signal simple rectification is pulsed at one, and the size variation of this pulsating direct current is complete
Consistent with the audio frequency signal amplitude variation of input, this signal further controls silicon-controlled 3 different current flow angle degree, makes silicon-controlled 3
Conducting changes conducting according to the amplitude of music, is connected to silicon-controlled 3 motor 4, can with the size of current of silicon-controlled 3 output and
Rotation, music amplitude is big, and the fast discharge of pump that motor 4 just turns is big, and with regard to small, music stops motor 4 and do not turn the small water yield of amplitude.
Further, adjustable voltage circuit includes silicon full-bridge 2, triode 5, frequency converter and resistance Rb, Rc, Re, silicon full-bridge
2 connect with audio signal input 1, and the base stage of triode 5 is connect with silicon full-bridge 2, and resistance Rb, resistance Rc are set to triode
