Smartphone Amplifier

This clever project boosts the sound coming from your smartphone. And all it takes is a little creative work at the band saw.

While the speakers on smartphones have improved over time, the sound coming from them doesn’t project very well. However, with a little shop time, you can create an amplifier like this one. The unique design dramatically increases the volume coming from the speaker located on the bottom of the phone. A tapered opening in the top accepts most phone models, even with a case. Of course, if you’re going to build a project, it’s nice to hone some woodworking skills along the way. For this project, you’ll spend some quality time working with your band saw.
