Problems solved by technology
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 has great significance for the improvement of the environment and energy saving and emission reduction, but the current noise power generation has a low utilization rate of sound wave energy

The present invention provides a noise power generation device and method based on human ear bone chain conduction. The output end of the receiving unit is connected to the end of the lever unit of the human ear ossicle chain. The other end is connected to the sound-electric conversion unit, the output end of the sound-electric conversion unit is connected to the input end of the voltage stabilizing amplifier circuit, and the output end of the voltage stabilizing amplifier circuit is connected to the storage battery. The invention causes the vibration of the vibrating membrane through the received sound wave, and then causes the vibration of the lever unit of the ossicle chain of the human ear, and the end of the lever unit of the ossicle chain of the human ear contacts with the piezoelectric film, causing the piezoelectric film to produce a positive piezoelectric effect Generate current, on the basis of improving the utilization rate of noise, fully apply the principle of bionics, so that the performance of the device has been greatly improved.
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 ...
