when the micro-cantilever beam (22) vibrates downwards, the micro-cantilever beam (22) deforms and bends downwards, at the moment, the lower part of the micro-cantilever beam (22) is positively charged, the upper part of the micro-cantilever beam is negatively charged, and one end of the micro-cantilever beam (22) simultaneously drives the circular conductive pressing block (23) to move downwards, so that the circular conductive pressing block (23) simultaneously drives one ends of the two conductive rods, which are far away from the conductive block (241), to move downwards, according to the lever principle, the end of the conductive block (241) moves upwards, the conductive block (241) at one end of the first conductive rod (24) is contacted with the first positive electrode plate (283), and the conductive block (241) at one end of the second conductive rod (26) is contacted with the first negative electrode plate (293) of the second positive electrode plate; thereby charging the first capacitor (31);
since the vibration amplitude of the micro-cantilever (22) tip is the largest, the recovery of vibration energy is also the largest here.
