Noise power generator

Abstract

The invention discloses a noise power generator which comprises Helmholtz cavities, guide pipes, generating devices, elastic walls, rear chambers, circuit boards and inner cavities. The noise power generator is a cuboid with the inner cavities, the Helmholtz cavities are arranged in the four side faces of the noise power generator respectively, the inner cavities penetrate through the top face and the bottom face of the cuboid, the outer sides of the Helmholtz cavities are communicated with the outside through the guide pipes, the elastic walls are arranged on the inner sides of the Helmholtz cavities, the rear chambers are arranged on the inner sides of the elastic walls, the generating devices are arranged in the rear chambers, the inner cavities are arranged on the inner sides of the rear chambers, the circuit boards are arranged in the inner cavities and are in load connection with the generating devices and the outside respectively, and therefore noise power generation control is achieved. According to the noise power generator, the Helmholtz cavities and paraphrase holes are effectively utilized to efficiently absorb noise, and the aim of utilizing sound energy in a centralized mode is achieved.

Description

technical field [0001] The invention belongs to the technical field of noise power generation, and in particular relates to a high-efficiency noise power generation device. Background technique [0002] Since entering the second industrial revolution, human beings have become more and more dependent on energy. It is foreseeable that the current energy crisis will not be alleviated in the future, and will even become more serious. According to the general estimates of economists and scientists, by about 2050, oil, the main traditional fossil fuel that humans rely on at present, will be exhausted, and its price will rise to a high level, which is not suitable for popularization and application. If new energy The system has not yet been established, and the energy crisis will sweep the world, especially the developed countries in Europe and the United States that rely heavily on oil resources. The most serious situation is that the industry has shrunk sharply, or even caused ...
