I saw a project posted the other day about a passive amplifier for your cell phone. I liked the idea and I'm always looking for small projects to use up the smaller scraps from other projects. It seems like I've got a constantly growing collection of boards that are too small to easily find a use for, but too big to feel good about getting rid of.
So when I saw the passive amplifiers, I immediately thought about my growing scrap pile and my wife and two daughters who are constantly all listening to music. So I made up these three pieces. The two for the girls are Mahogany tops with cherry bottoms and the one for my wife is Mahogany on both side. All three have baltic birch ply center panels.
The layers are all 3/4" thick and I made up a template for the centers so I could just pattern route them. The top layers have a 5/8" slot cut to fit an iPhone. The finish is just a couple of coats of satin lacquer.
This was a quick and easy project and they work surprisingly well. More importantly, the LOML and the kids think they are great.

I'm not sure the size matters all that much, I just kind of picked a size that seemed in line with the proportions of the project I saw. Mine is 10" wide and 4" deep.
There is probably some fancy math you could do to get the correct curvature for the inside, but I don't think it matters all that much. On mine, since it was 4" deep and I wanted the phone slot to be 3/4" from the back, that meant the distance from the cutout to the front would be 3 1/4". I wanted to have about a 3/4" reveal on the plywood on each side of the opening, so I just set my compass to s zip that seemed about right and drew an arc on each side. The key thing is you wan to have clearance under the speakers for your phone, so as long as the opening is wide enough in the back for that, you can do what you want with the opening and the curvature.
The angles on the side I just eyeballed to an angle I liked which ended up about 10 degrees.
Just to point out, this is not my idea, I modeled mine on nblazek's build and he based his on one he saw on line.
There are some other versions of this as well with different designs if you search the web.
If I had thought of it before I did the glue up, I would have routed out a small slot in the ply layer to let someone insert a charge cord. This would also require you to split the support block into two narrow blocks and move them to the side to allow the charge cord to clear. Just making sure you don't put them under the speakers and block the sound.

Well, I just had some baltic birch plywood scrap so that was one reason, but I also like look of the BB layers. You could use whatever you have handy, I wanted to have some contrast for the middle and the ply was at hand.
