<p>The present invention relates to an energy harvester for controlling a resonance frequency. The present invention includes: an induction coil unit which is wound around a lower housing; a magnet unit which vibrates up and down within the induction coil unit by external vibration; an upper housing which is combined with the lower housing; a stopper which is fixed on the upper side of the upper housing; a spring unit for resonance frequency control which is combined and fixed on the magnet unit to rotate on the stopper to be rotatable and controls the length of an area to be transformed in response to the external vibration according to the degree of rotation; and a zig unit for rotation control which adheres to the spring unit for resonance frequency control and controls the rotation degree of the spring unit for resonance frequency control by rotating step by step by manual operation of a user. According to the present invention, the present invention supplies the energy harvester in an electromagnetic induction method for controlling the resonance frequency to be matched efficiently with the vibration frequency of various external vibration sources, minimizes a device, simplifies manufacturing processes, and reduces manufacturing costs.</p> |
