As an entertainment and interactive project, shouting springs are based on the principle that the output frequency of the inverter is controlled by the analog voltage output of a human shout. The speed of the water pump can be controlled to realize the change of the amount of water output and the spraying height of the nozzle.

The stage of the shouting springs has been lit. The cartoon image of the cute zodiac rat is particularly beautiful against the background of the lights.

From 4:30 pm to 11 pm, every visitor can have a two-minute experience interaction time every half an hour.
