Abstract

 In this paper, a piezoelectric beam is designed to receive sound energy in a real environment. The electrical energy received from this beam can be stored in a battery or used directly by electrical circuits. The use of two simulations of copper and piezoelectric beams, including polyvinylidine fluoride, in which the length of the piezoelectric layer is shorter and located at the optimal point of the copper beam, are used in this simulation. The 100 dB speaker sound power is applied in a 1 cubic meter room considering the presence of air in the environment to the pole in the middle of the room. By making the beam 7. 8 cm long, the first bending frequency of the beam reaches close to 100 Hz. By stimulating the beam at this bending frequency, the noise effect reaches its maximum value and eventually leads to the production of a voltage of about 70 mV.
