Scream Fountain: As a new type of water feature entertainment, it operates by converting the pitch and duration of human voice into analog voltage, which controls the frequency output of the inverter. Changing the frequency alters the motor speed, which in turn modifies the pump pressure. This allows for controlling the pump's speed, adjusting the water flow rate and the height of the jet. Consequently, it determines the fountain's height and duration, making it an engaging and aesthetically pleasing water display project.
