Eco-Friendly Speakers Made From Empty Plastic Bottles

Innovative system that uses recycled materials to amplify sounds.


Designers Lin Nien-An and Cheng Ya-Fang have created the Green’s Voice system that turns empty plastic bottles into portable speakers. The package consists of a speaker driver with a custom designed rubber cradle that can be mounted to any used bottle. The bottle functions as an enclosure to amplify the sound.

The speakers are also made of environmentally friendly, biodegradable PLA material. Paper batter is also used to power the device, and offers 10 times longer lifespan than lithium battery.
