音樂噴泉是通過千變萬化的噴泉造型，結合五顏六色的彩光照明，來反映音樂的內涵及音樂的主題，一座好的音樂噴泉，水形的變化應該能夠充分地表現樂曲。是在程序控制噴泉的基礎上加入了音樂控制系統，計算機通過對音頻及MIDI 信號的識別，進行譯碼和編碼，最終將信號輸出到控制系統，使噴泉的造型及燈光的變化與音樂保持同步，從而達到噴泉水型、燈光及色彩的變化與音樂情緒的完美結合，使噴泉表演更加生動更加富有內涵及體現水的藝術。
音樂噴泉可以根據音樂的高低起伏變化。用戶可以在編輯界面編寫自己喜愛的音樂程序。播放系統可以實現音樂、水、燈光氣氛統一，播放同步。
根據播放的音樂來控制水柱，達到與音樂同步的效果，而水柱是由水泵來控制的，而水泵是由三相異步電動機組成的，三相異步電動機的轉速如果通入工頻電源，轉速是不變化的，變頻器是專門針對電機調速的裝置。
由變頻器控制電機的轉速，使水柱發生變化。改變頻率就改變了電機的轉速，也就改變了水泵的壓力，音樂的不同頻率經單片機處理送到變頻電機的控制端，使電機轉速隨音樂的音調，節奏，和強弱變化，水泵的壓力隨之變化，噴岀的水就有了高低變化，而且是由幾套設備對多組噴嘴實施控制噴泉的形成是水泵。
將音樂的節奏和強度轉變為控制信號，此信號再控制一個電壓控制器件，電源經過這個電壓控制器件后，輸出電壓也隨音樂的變化而改變，然后控制水泵電機。
Music fountain reflects the connotation of music and the theme of music through the ever-changing fountain shape and colorful color lighting. A good music fountain should fully express the music through the change of water shape. The music control system is added on the basis of the program control fountain. The computer decodes and encodes the audio and MIDI signals, and finally outputs the signals to the control system, so as to keep the shape and light changes of the fountain synchronized with the music, so as to achieve the perfect combination of the water type, light and color changes of the fountain and the music emotion, so as to make the fountain performance more vivid, richer in connotation and reflect the art of water.
Music fountains can vary according to the ups and downs of music. Users can write their favorite music programs in the editing interface. The playing system can realize the unity of music, water and light atmosphere and play synchronously.
The water column is controlled according to the played music to achieve the effect of synchronization with the music. The water column is controlled by the water pump, and the water pump is composed of three-phase asynchronous motor. If the speed of three-phase asynchronous motor is connected with power frequency power supply, the speed will not change. The frequency converter is a device specially for motor speed regulation.
The speed of the motor is controlled by the frequency converter 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 processed by the single chip microcomputer and sent to the control end of the variable frequency motor, so that the speed of the motor changes with the tone, rhythm and strength of the music. The pressure of the water pump changes accordingly, and the water sprayed changes. Moreover, several sets of equipment control multiple groups of nozzles. The formation of the fountain is the water pump.
The rhythm and intensity of the music are transformed into a control signal, which controls a voltage control device. After the power supply passes through the voltage controller, the output voltage also changes with the change of the music, and then controls the water pump motor.
