基于压电效应的声波发电机实验研究

EXPERIMENT AND STUDY ON SONIC GENERATOR BASED ON THE PIEZOELECTRIC EFFECT

噪声在人类的生产生活中随处可见,而至今还没有有效的手段对声音能量来进行收集与利用。本实验通过亥姆霍兹共鸣器对声音能量进行收集,并利用压电陶瓷进行声电转换,得到的微小电流利用LTC3588-1进行收集并加以利用。得出结论:虽然通过亥姆霍兹共鸣器可以有效收集声波能量,但压电陶瓷的低效阻碍了声波发电的进一步推广。

Noise can be heard everywhere in human life,and so far there is no effective means of sound energy to be collected and utilized.In this experiment Helmholtz resonator was used to collect energy,and piezoelectric ceramics were also used to accomplish acoustic- electric conversion,LTC3588- 1 was used to collect and utilize the obtained slight energy.Get a conclusion: Although by Helmholtz resonator,acoustic energy can be effectively collected,but inefficient piezoelectric ceramics hindered the further promotion of sonic generator.
