Piezoelectric oscillator structure for vibration energy recycling

Abstract

The invention discloses a piezoelectric oscillator structure for vibration energy recycling. The piezoelectric oscillator structure comprises a base structure and a piezoelectric electromechanical coupling electricity generating unit fixed on the base structure. The piezoelectric electromechanical coupling electricity generating unit comprises at least a pair of piezoelectric electromechanical coupling generators. The piezoelectric electromechanical coupling generator comprises beams of variable cross-sections, permanent magnet mass blocks and piezoelectric elements integrated on the surfaces of the beams of variable cross-sections. The permanent magnet mass blocks are fixed at the free ends of the beams of variable cross-beams. The root of the beam of variable cross-section is fixed on the base structure. The thickness of the free end of the beam of variable cross-section is less than the thickness of the other end. Opposite sides of each permanent magnet mass block have the same polarity and have a gap. The piezoelectric oscillator structure is added with an amplitude limiting structure used for recycling impact vibration energy, thereby protecting the internal cantilever beam structure, and improving the vibration energy recycling efficiency; the amplitude limiting structure can recycle upward vibration energy of various directions in a two dimensional plane vertical to a neutral line; each beam of variable cross-section adopts a variable cross-section design, so that the piezoelectric element has equal strain in beam length direction while the shape of the piezoelectric element is not changed, and the electromechanical coupling coefficient of the structure is improved.

AI Technical Summary

Benefits of technology

This patented technology helps reduce noise caused by external forces on electronic devices such as mobile phones or tablets during use. It uses an improved type called a stinger that reduces impact force when hitting objects with high acceleration levels. By adding this device to the phone's main body instead of just placing it inside, there are benefits like better sound quality and reduced battery power consumption compared to traditional designs used outside.

Problems solved by technology

This patented technical problem addressed in this patents involves improving the performance and reliability of electronic systems without relying heavily upon their own sources for energy generation due to limitations associated with current techniques used for generating energy. One solution proposes utilizing renewable resources instead of disposables, but these solutions may require significant effort and expense. Another approach suggests integrating certain components within the system itself rather than requiring individual hardware replacements. Additionally, exploring new ways to efficiently collect and reuse energy becomes increasing importance over longer periods of time.
