Abstract

The utility model relates to a power generating device for absorbing noise. The power generating device comprises a bottommost rotating disc, a supporting frame, a pivot which can move back and forth on the supporting frame, and a trumpet-shaped noise receiver on the topmost of the supporting frame. A sound-electricity converter is arranged on the right center of the noise receiver. The supporting frame is provided with a power conditioning device. The back of the supporting frame is provided with an electric energy storage device. The sound-electricity converter is arranged in a honeycomb shape and comprises a Helmholtz resonator and PVDF piezoelectric films. The PVDF piezoelectric films are arranged behind the Helmholtz resonator. The Helmholtz resonator and the parallel connected PVDF piezoelectric films are fixed on the noise receiver by a set of PBT polybutylene telephthalate clamping grooves. Signals of the PVDF piezoelectric films are sent to the power conditioning device and processed, and then electric energy is stored in the electric energy storage device. The generated electric energy can be provided for low-power lighting and supplying power for low-power loads after electric energy is rectified, converted and stored so that the power generating device for absorbing noise is suitable for occasions like a KTV, a bar, a highway, an airport, etc. and thus noise is changed into valuables.
