Abstract

The invention provides a noise power-generating device and noise power-generating equipment consisting of the same. The noise power-generating device comprises a sound wave collecting pipe, wherein one end of the sound wave collecting pipe is opened; an air-isolating and sound-transmitting thin film is sealed at the opening of the sound wave collecting pipe; a trumpet-shaped inlet is also formed at the opening of the sound wave collecting pipe; a sound-isolating plate is arranged outside the sound wave collecting pipe 4; one end of the sound-isolating plate is connected with the trumpet-shaped inlet 1; the other end of the sound-isolating plate is connected with the closed end of the sound wave collecting pipe 4; the sound-isolating plate and the outer wall of the side surface of the sound wave collecting pipe form a cavity; a plurality of columns of acoustical-electrical converting units which are uniformly arranged along the axial direction are arranged on the side surface of the sound wave collecting pipe; each of the acoustical-electrical converting unit comprises a helmholtz resonator with a resonating cavity and an acoustical-electrical converter connected with the helmholtz resonator; the acoustical-electrical converter comprises a vibrating film arranged in the cavity in the tail end of the resonating cavity and connected with a coil through a connecting rod; a coil is sleeved on a magnetic pole; and the magnetic pole is arranged on the sound-isolating plate. The coil is connected with an output bus through a current-collecting wire, so that the mechanical energy of noise is converted into electric energy.

Description

technical field [0001] The invention belongs to the technical field of power generation devices, in particular to a noise power generation device and noise power generation equipment composed of the device. Background technique [0002] With the increasingly severe energy problems in our country, the improvement of people's material living standards and the development of the economy and society, people's life and production electricity consumption has increased rapidly, and it is more urgent and important to tap potential energy and collect and utilize it. Therefore, using some seemingly useless or even polluting substances in life will greatly reduce our dependence on traditional energy sources. Noise is such an "energy source". Noise itself is a kind of mechanical wave, which carries energy. The noise collection and conversion power generation device of the research and development system is used in actual life and production, which closely conforms to the idea of ​​"ene...
