Abstract :
There is huge scarcity of electricity in Nigeria and other developing countries especially in rural
communities, and for carrying out our daily activities, we need electricity. Mobile phones have become part
of our basic daily needs and these mobile phones require to be charged always. This project was aimed at
designing and implementing an electrical energy generator using sound energy, it converts sound into
electricity with the use of transducers such as the piezoelectric crystals and condenser microphones. The
system has a rechargeable battery within which the converted energy is being stored for later use. Its ability
to detect sound is omnidirectional and can charge any external device that requires a voltage of not more
than 2V directly from the energy generated using sound and 4V from energy stored in the inbuilt
rechargeable battery. The system has been tested in various environments to confirm its capability to work
with different sources of noise. The efficiency of the system has been proven to be effective especially in
places with high intensity noise.
