How music fountains work

The fountain can spray water into various design shapes through certain design principles, and the types of fountains have also appeared with development. Next, let's take a look at the principle of music fountain design.
The working principle of the music fountain is to control the water column according to the music played 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. When power frequency power is applied, the rotation speed does not change. The inverter is a device specifically for speed regulation of motors. The frequency of the motor is controlled by the inverter to change the water column.
Changing the frequency changes the speed of the motor and the pressure of the water pump. The different frequencies of the music are sent to the control end of the variable frequency motor by a single-chip processor, so that the speed of the motor changes with the tone, rhythm, and strength of the music. With this change, the sprayed water has a high and low level, and the formation of the fountain is controlled by several sets of equipment to form a water pump.
The rhythm and intensity of the music is converted into a control signal. This signal then controls a voltage control device. After the power source passes this voltage control device, the output voltage also changes with the change of the music, and then controls the pump motor.
