The Sound Energy-Based Powerbank is a device that promotes sound as a new source of renewable energy, converting sound to electrical energy and storing it in a battery. The study used developmental and experimental design, wherein the researchers conceptualized the design and features of the device. The device was assembled appropriately in accordance with the design and features. The salient findings of this study include the capability of the SEBPB to convert sound energy to useful electrical energy while being economically effective. The device has the unique ability to charge in different noisy or loud areas and is capable of improving the battery life of electronic devices. Overall results show that the Sound Energy-Based Powerbank is deemed functional in utilizing sound energy to generate' electrical energy.enTECHNOLOGY::Electrical engineering, electronics and photonics::Electric power engineeringThesis
