This study is about the research and development of mechanical vibration obtained from sound waves, obtaining energy with ambient energy in an acoustic sense. Piezoelectric material has been used to generate electrical energy. In order to create mechanical vibration, the sound is produced from the speaker, the sound produced is induced on a piezoelectric material, the frequency of the sound is propagated as a sinus wave, and the results are examined on the computer. The experiment series is then carried out by the piezoelectric transducer. The piezoelectric transducer passes through the full rectifier circuit; the results are measured with a voltmeter and oscilloscope. Experiment from three cases is studied, in different geometries; in other words, by keeping the position of a piezoelectric transducer constant, is evaluating the effect of distance and temperature changes.
