Studies have shown that different types of tissue and cellular structures can be brought into resonance by means of vibration stimuli of different frequencies, thereby delivering vibration information with specific characteristics, such as delivering vibrations with characteristic frequencies (tone characteristics), amplitude dynamics, sub-frequency mixing characteristics, interfering with the physiological activity of the resonant tissue.
However, the current massage device based on physical vibration usually adopts a single mode vibration mode, such as a single frequency continuous vibration mode and a plurality of frequency alternating vibration modes, and generates a massage relaxation effect by vibrating skin and muscle.

There is therefore a need for improvements in the prior art that overcome the deficiencies in the prior art.
