There have been plenty of different passive amplifiers for smartphones, but I have to say that this one definitely stands out from the crowd. The Bomie’s Boom System is quite large, and could be something interesting to have in your living room if you don’t believe in powered speakers.
The Bomie’s Boom System is a passive acoustic amplifier for smartphones that was handmade by Malawian woodcarvers and wood-turning specialists. It amplifies the sound of the paltry integrated smartphone speaker thanks to the large, parabolic horn shape. The carved tube is made out of solid wood, and the slot at the base allows users to easily slide their phones in and out.
It was developed by the Dutch designer Jeroen Bomers and hopefully, you’ll be able to pick one up sometime soon.
