ABSTRACT:

Power generation is most important thing in this world. This power generation is evolved from lot of updates with various methodologies. Present days we spend much amount of cost for power generation which causes the pollution in environment. Due to pollution and lack of resources we need to move on to renewable sources for power generation. We have known that we are having wind mill, solar panel, etc. are renewable energy sources, but they also much costlier. Our aim is we need to spend low cost and get proper efficient & regulated output from the design or sources. By the theme we proposed a solution to generate energy from sound waves. We design a circuit by using Acoustic meta material, piezoelectric transducers, step-up transformer, BJT 2N 3904, Bridge rectifier, capacitance, switch, chopper, a rechargeable battery. Here we use the principle piezoelectric effect, which  converts mechanical stress into electrical energy when we apply mechanical stress to it and it converts the electrical energy into mechanical stress when we apply electrical energy it. The existing methods were failed to give solution for induction of  back- emf or reverse voltage in the circuit and also fail to give  regulated output. We fulfill the failures which is occur in the existing proposals.
