Noise power generation apparatus and method based on human ossicular chain type conduction

Abstract

The invention provides a noise power generation apparatus and method based on human ossicular chain type conduction. The noise power generation apparatus comprises a sound wave receiving unit, a vibration membrane, an artificial human ossicular chain lever unit, an acoustic-electric conversion unit, and a voltage-stabilizing amplification circuit, wherein the output end of the sound wave receiving unit is connected with one end of the artificial human ossicular chain lever unit; the vibration membrane is arranged between the output end of the sound wave receiving unit and one end of the artificial human ossicular chain lever unit; the other end of the artificial human ossicular chain lever unit is connected with the acoustic-electric conversion unit; the output end of the acoustic-electric conversion unit is connected with the input end of the voltage-stabilizing amplification circuit; and the output end of the voltage-stabilizing amplification circuit is connected to a storage battery. According to the noise power generation apparatus, the vibration of the vibration membrane is caused through the received sound wave; then the vibration of the artificial human ossicular chain lever unit is caused; the tail end of the artificial human ossicular chain lever unit is in full contact with a piezoelectric thin film, so that the piezoelectric thin film can generate a positive piezoelectric effect to generate current; and therefore, on the basis of improving the noise utilization rate, a bionics principle is fully utilized, so that the relatively high improvement of the performance of the apparatus is realized.

Description

technical field [0001] The invention belongs to the technical field of noise power generation, in particular to a noise power generation device and method based on human ear bone chain conduction. Background technique [0002] With the development of science and technology, it is imperative to develop new energy sources. At the same time, energy saving and emission reduction has also become a hot topic in improving environmental issues. As a source of public environmental pollution, noise affects people's work and life, and is one of the four major pollutions in the world. The traditional way to control noise pollution is to set up isolation or protection on its transmission path. Although the harm of noise to human beings has been weakened to a certain extent, this part of energy cannot be effectively used. The emergence of noise power generation is of great significance to the improvement of the environment and energy saving and emission reduction, but the current noise ...
