This acoustic cell phone amp provides an 8-10 db boost, and has access for a charging cable so that you can charge your phone while listening to music. Made of walnut and finished with walnut oil. This is my “mass production” holiday gift project for this year. After you get the first one completed, you can produce these in about an hour apiece.

Build video is available here: https://youtu.be/yRHdsFFNo-I

Congrats on a quick top 3.

You’ll get more volume the closer you get to a true horn shape.

Thanks, Rick. Yes, also found that the output shape matters a lot. I experimented with a lot of designs and this one produced the best combination of amplification and tonal quality enhancement among my prototypes. I’m sure it could be better, though.
