Picture of IPhone Pocket Speaker

This is a completely wireless, battery-free, eletronic-free passive phone speaker that is literally not much bigger than your cell phone when folded up. I made a wooden passive speaker a couple of years ago for my wife, which she uses quite often, but it's not portable. This one she can throw in her bag and use when she works as a nanny to play music for the kids.

Step 1: Materials and Drawings

The materials I used included a thin hard plastic garage sale sign, an old denim shirt, two sided tape, duct tape, and a couple of small rare earth magnets.

Start off by cutting the plastic to the given sizes and shapes with an olfa knife on a cutting board.

This looks so simple yet so advanced. It works and it does not even need additional energy. Thanks for sharing an eco-friendly idea that better our daily lives though on small scale.

Sorry no I don’t have an Etsy shop, most of the thing I make are one offs. Hope you give it a try to make your own.
