▶️ This project demonstrates the conversion of sound energy into electrical energy using piezoelectric sensors and a speaker diaphragm. When exposed to mechanical vibrations generated by sound, the piezoelectric sensors produce voltage. This output is first used to charge a 4V rechargeable battery, which acts as the primary energy storage. A DC–DC boost converter then steps up this voltage to around 15V, enabling charging of a 12V battery. The stored energy in the 12V battery is fed into a DC–AC inverter rated at 15W, which provides 220V AC output. The generated AC power is capable of powering small loads such as an LED bulb or fan, proving the concept of energy harvesting from sound vibrations.

Sound Source: Speaker / ambient sound vibrations.
Piezoelectric Sensors: Generate small AC voltage from mechanical pressure.
Rectifier & Charging Circuit: Converts AC to DC and charges the 4V battery.
Voltage Booster (Step-Up Converter): Boosts 4V to 15V for charging the 12V battery.
12V Battery: Stores sufficient energy for later use.
DC–AC Inverter (15W): Converts 12V DC into 220V AC output.
Output Load: Small AC bulb is illuminated as Proof of working.

The proposed system successfully demonstrates the conversion of sound vibrations into usable electricity. By using a combination of piezoelectric sensors, energy storage, voltage conversion, and an inverter, small AC appliances can be powered sustainably. This project showcases a renewable and innovative approach to energy harvesting and is highly suitable for final year projects, exhibitions, and practical demonstrations.
