The increasing cost of electronic devices and the growing problem of environmental pollution highlight the need for simple, sustainable alternatives. This project, EcoVoice: Homemade Acoustic Speaker Using a Water Bottle, introduces an eco-friendly speaker made from recycled materials that amplifies sound without the use of electricity. Using a plastic water bottle as a resonating chamber, along with a cardboard roll and basic tools, the device enhances sound through vibration and resonance. When a mobile phone is placed within the structure, sound waves travel into the bottle and are naturally amplified. This project demonstrates key scientific principles such as sound wave propagation and resonance while encouraging creativity and environmental awareness. EcoVoice provides a low-cost, portable, and sustainable solution, making it ideal for students and educational applications.
