The working principle of the musical fountain is to control the water column according to the played music to achieve the effect of synchronization with the music. The water column is controlled by a water pump, and the water pump is composed of a three-phase asynchronous motor. If the speed of the phase asynchronous motor is connected to the industrial frequency power supply, the speed will not change. The frequency converter is a device specifically designed for motor speed regulation. The frequency converter controls the speed of the motor to change the water column.

Changing the frequency changes the speed of the motor, and also changes the pressure of the water pump. The different frequencies of the music are processed by the microcontroller and sent to the control end of the variable frequency motor, so that the motor speed changes with the tone, rhythm, and frequency of the music. As the strength changes, the pressure of the water pump changes accordingly, and the sprayed water changes in height, and multiple sets of nozzles are controlled by several sets of equipment

The fountain is formed by a water pump.

Convert the rhythm and intensity of music into a control signal. This signal then controls a voltage control device. After the power passes through this voltage control device, the output voltage also changes with the change of the music, and then controls the water pump motor< /p>
