Abstract Eco Speaker
The Eco Speaker is a DIY, eco-friendly phone amplifier made from recyclable materials like paper cups and cardboard tubes. By inserting a phone into a tube with cups at both ends, it amplifies sound through reflection and diffusion—no power needed. It's lightweight, portable, low-cost, and promotes sustainability with reusable materials, ideal for music, movies, or calls.
