[0002] Vibration is a universal phenomenon in the universe, which can be generally divided into macroscopic vibration (such as earthquakes and tsunamis) and microscopic vibration (thermal motion of elementary particles and Brownian motion). Some vibrations have relatively fixed wavelengths and frequencies, while some vibrations do not have fixed wavelengths and frequencies. When one of two objects vibrates at the same frequency, the other object can vibrate at the same frequency. This phenomenon is called resonance, which can bring many benefits and harms to humans.

[0003] The vibration device in the prior art generally has only a single vibration amplitude, and the vibration amplitude cannot be adjusted according to actual needs. It is also necessary to replace vibration equipment with different amplitudes, which is complicated to operate and brings trouble to people.
