The premise of generating a sound control effect: touching the product allows the sensor to sense or the sound emitted around it is large enough for the sensor to sense the sound control effect.(Special note: the distance of the sensing sound of each sensor is not exactly the same, specifically based on actual conditions.)
The battery needs to have three sections of No. 5, and the product itself does not have its own battery.
