Abstract

The invention provides an automobile-mounted noise generating set. The automobile-mounted noise generating set comprises an automobile-mounted noise collecting unit, a sound-electricity conversion unit and an electric energy storing unit, wherein different arrangement ways and collecting devices are adopted according to the noise and structural characteristics of different positions of the automobile. The main structure of the set comprises a noise collector and a sound wave conduit in the automobile noise collecting unit, a sound pressure amplifier and a sound-electricity converter in the sound-electricity conversion unit, and a current conditioning circuit, an electric energy storage and an automobile-mounted storage battery in the electric energy storing unit. According to the automobile-mounted noise generating set, the aim of converting the noise energy of the automobile into usable electric energy is fulfilled on the premise of not influencing the normal running performance of the automobile, and waste energy is recycled. The automobile-mounted noise generating set further has the advantages of high power generation efficiency, simple structure, convenience in installing, high practicability, small occupied size, high 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...
