Smartphone Amplifier
Boost smartphone sound with this passive wooden amplifier. Easy band saw build with inlays, curves, and custom touches.
Boost your smartphone’s sound—no batteries or electronics required. This stylish, passive wooden amplifier naturally increases volume using clever acoustic design, all crafted with basic band saw techniques. Whether you're in the shop or around the house, this project adds both function and elegance to your space.
The tapered slot fits most smartphones (even with cases), directing sound through an internal chamber to dramatically enhance projection. Along the way, you’ll hone essential woodworking skills like resawing, curve cutting, and precision gluing. Add a custom touch with contrasting inlay strips made from your choice of hardwoods.
This is a fun, functional project that makes a great gift—or a useful upgrade to your own daily setup.
