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.
