Abstract

The embodiment of the invention provides an acoustic wave power generation method which comprises the following steps: collecting acoustic signals; acting on a piezoelectric material by utilizing the acoustic signals; collecting and outputting current generated by the piezoelectric material. The acoustic wave power generation method can widely provide power supply support for electronic products of which the sizes become smaller and smaller or wearable equipment.

Description

technical field [0001] The invention relates to power generation technology, in particular to a piezoelectric material-based acoustic wave power generation device. Background technique [0002] Sound is produced by the vibration of objects. It is a phenomenon that can be encountered in daily life. It is an important channel for people to exchange information and communicate with each other. It is present all the time. The form of sound propagation is sound waves. There are three types of sound waves: ultrasonic waves, infrasound waves, and sound waves that can be heard by the human ear. Among them, the frequency of sound waves that can be heard by the human ear is between 20HZ and 20000HZ. The sound waves above 20000HZ are called ultrasonic waves, and the sound waves below 20HZ are called infrasound waves. become noise. Wonderful music refers to the sound that makes people feel comfortable or enjoys hearing. It can make you relax, enjoy your body and mind, and get rid of ...
