Do You Know The Music Fountain Principle
- Sep 11, 2018 -

Changing the frequency changes the speed of the motor, which changes the pressure of the pump. The different frequencies of the music are sent to the control end of the variable frequency motor by the single-chip microcomputer, so that the motor speed changes with the pitch, rhythm, and strength of the music. The pressure of the water pump changes accordingly, and the water of the sneeze has a high and low change, and the formation of the control fountain by several sets of equipment is a water pump. The rhythm and intensity of the music is converted into a control signal, which in turn controls a voltage control device. After the power supply passes through the voltage control device, the output voltage also changes with the music, and then the water pump motor is controlled.
