About the atomization film

The ultrasonic atomizer uses electronic high-frequency oscillation (the oscillation frequency is 1.7MHz or 2.4MHz, which exceeds the range of human hearing, and the electronic oscillation is not harmful to humans and animals), through the high-frequency resonance of the ceramic atomizer, to remove liquid water The structure breaks up to produce natural and elegant water mist, without heating or adding any chemical reagents.

About piezoelectric ceramic sheet

2020-09-07

Piezoelectric ceramic chip is an electronic sound element. Piezoelectric ceramic dielectric material is placed between two copper circular electrodes. When an AC audio signal is connected to the two electrodes, the piezoelectric chip will frequency according to the size of the signal. Vibration occurs and a corresponding sound is produced.
