About Product:Using the principle of eccentric wheel, the so-called eccentric wheel means that the axis of the wheel is not on the center of the wheel, when the wheel is moving, it will not be on the same plane, thus causing the object to vibrate. This is basically the same as the eccentric vibration produced by a mobile phone.
