The EchoBuddy Stand is an innovative educational tool that integrates passive acoustic amplification and ergonomic design into a simple, low-cost mobile phone holder. Developed by primary school students using recycled materials—ice cream sticks and a paper cup—this prototype addresses common user needs: sound amplification, hands-free viewing, and simultaneous charging. The structure uses a triangular support system to enhance stability, reflecting basic engineering principles. The amplifier mechanism harnesses natural resonance to boost audio output without electricity. This project fosters early STEM engagement and sustainable thinking, aligning with SDG 4, 9, and 12. It demonstrates how simple materials can solve practical problems through creative engineering.
