    • PURPOSE: A self-powered power generator is provided to generate more electricity by amplifying the physical vibration of a piezoelectric element through a vibration weight. CONSTITUTION: A body part(200) includes an upper frame(220) and a lower frame(240). A piezoelectric element part(400) is arranged under the lower frame as the cantilever type. The piezoelectric element part changes the physical vibration to the electrical energy. A drive circuit part(600) is electrically connected to the piezoelectric element part. The drive circuit part rectifies and stores the electrical energy transformed with the piezoelectric element part. A load connection part(800) is formed in the upper side of the upper frame. The load connection part is electrically connected to the drive circuit part.
    • 目的:通过振动重量放大压电元件的物理振动,提供自供电的发电机来产生更多的电能。 构成:身体部分(200)包括上框架(220)和下框架(240)。 压电元件部件(400)作为悬臂式布置在下框架的下方。 压电元件部分将物理振动改变为电能。 驱动电路部(600)与压电元件部电连接。 驱动电路部对整流并存储与压电元件部变换的电能进行整流。 负载连接部(800)形成在上框架的上侧。 负载连接部电连接到驱动电路部。
