Electromechanical equipment box noise piezoelectric generating system and method

Abstract

The invention provides an electromechanical equipment box noise piezoelectric generating system and method. A wavy piezoelectric panel is arranged between electromechanical equipment as a noise sourceand an electromechanical equipment box, the electromechanical equipment vibrates during running to generate noise sound wave, the noise sound wave is transmitted to the piezoelectric panel in the internal space of the electromechanical equipment box, so that the piezoelectric panel deforms repeatedly and its wavy structure is compressed under vibration of the noise sound wave so as to generate electric power and transmit the electric power to a current adjusting device. The piezoelectric panel is utilized to absorb and convert the noise sound wave into electric power and then outputs the electric power for storage, and therefore, the technical problem that great quantity of noise sound wave generated by the electromechanical equipment cannot be utilized is solved, and the electromechanical equipment box noise piezoelectric generating system and method has the advantages of achieving simple structure, having wide application range, and having functions of sound absorption and power generation.
