The user adjusts the control unit to control the difference between the rotation speed and the rotation phase of the first and second motors, so as to obtain different vibration amplitudes and vibration frequencies, and then obtain the best vibration intensity feeling. Wherein, the known technology uses a double eccentric block, a rotation speed and a phase difference to generate the best vibration intensity, which is different from the efficacy and purpose expected to be achieved by the technical content of the present invention.

Furthermore, as in the known invention patent of I619343, it refers to a wave gear device and friction engagement wave device for vibration power generation. In the wave gear device, the flexible external gear is oriented toward the flexible gear by the wave generator. The radial direction is bent and partially meshes with the rigid internally toothed gear. As the wave generator rotates, the meshing position of the rigid internally toothed gear and the flexible externally toothed gear moves in the circumferential direction. The flexible externally toothed gear includes a vibration power generation unit and a detection unit.

The electronic circuit device converts the charge into a voltage, directly uses the electricity required by the machine's own electrical device, and stores it in an energy storage device for other purposes. However, the way in which the piezoelectric force is used to generate electric charges by the vibration force, and then the electric charges are converted into voltage by the electronic circuit device, is different from the way in which the piezoelectric energy generating element generates electric energy directly by the vibration energy of the invention. In addition, the vibration force refers to a single source of vibration, which is different from the centrifugal force and vibration ability of the present invention that can generate different sizes.
