Problems solved by technology
[0002] At present, vibrations are ubiquitous in the surrounding environment. These vibrations will cause structural damage to mechanical equipment and shorten their service life. At the same time, they will cause certain noise pollution to the environment, which not only reduces the reliability of mechanical equipment, but also generates a lot of noise pollution.
[0003] However, mechanical vibration contains a wealth of energy, and related technologies have not effectively collected and utilized this vibration energy, which easily leads to waste of energy
