Abstract

The present invention is a vehicle-mounted noise generating device, which includes a vehicle-mounted noise collection unit, an acoustic-electric conversion unit and an electric energy storage unit, wherein: different arrangements and collection devices are adopted according to the noise and structural characteristics of different parts of the vehicle. The main structure of the device includes: the noise collector and the acoustic waveguide in the vehicle noise collection unit, the sound pressure amplifier and the acoustic-electric converter in the acoustic-electric conversion unit, and the current conditioning circuit, electric energy storage and vehicle battery in the electric energy storage unit . The invention achieves the purpose of converting the noise energy of the automobile into usable electric energy without affecting the normal driving performance of the automobile, and realizes the reuse of wasted energy. The invention also has the advantages of high power generation efficiency, simple structure, convenient installation, high feasibility, small occupied volume, good reliability and the like.

Description

technical field [0001] The invention relates to the field of energy regeneration, in particular to a device for power generation of vehicle-mounted noise for various types of automobiles. Background technique [0002] Noise pollution is quite harmful to people's life and health. In today's society where the mass production of automobiles is increasing year by year, the noise pollution of automobile driving has become a problem that cannot be ignored. While considering noise as a kind of environmental pollution, it must be recognized that noise is also a potential energy source with a considerable energy value. For example, a jet aircraft with a noise level of 160dB (A) has a sound power of about 10kW; a noise level of 140dB (A) ) of a large blower with a sound power of 100W, and the noise generated by sound sources such as automobiles and stereos also has a large energy value. In order to improve people's living environment and recycle this part of energy, we use a sound en...
