We’ve all experienced these moments where we wished the speaker on our smartphone was louder. eco-made has come up with a simple amplifier for the iPhone that is able to increase the sound emitted. What makes these ‘eco-amps’ terrific, is that they’re made from 100% recycled paper.
It arrives in a flat envelope, so you’ll need to do a little origami work to fold it into shape. But seriously, it’s just a piece of presumably slightly thicker paper that’s been folded in the shape of a cone, so you could probably just do the same thing by cutting up an old shoebox.

After all, despite the name, there is no actual amp here. It’s more like the horn from an old phonograph. We’ve all rolled up a paper cone to use like a makeshift megaphone and this works in basically the same way.
Creating company eco-made of Los Angeles claims that you’ll increase the volume on your iPhone speaker to 30dB.
