I’ve seen a few designs of this now, and was very curious about building one. So, I grabbed some scrap walnut and made one. It changes the tone of the music slightly, but importantly, it amplifes the sound a little bit and projects outward. My son loves it and has used it non stop since I built it. A pretty fun little project anyway.

Here’s the website with some plans: http://www.woodworkcity.com/2011/11/23/iphone-amplifier-speaker-out-of-wood/

Fun, easy, and quick results.

I’m working on making this now too. How thick were the different layers? All 3/4” ?

I saw the plans online and thought they were great, I plan on making one for my iPhone, I have a couple other projects I need to get done first, like a cabinet for the wife’s new laundry sink and my cigar box resonator geetar that I started. As Red Green wood say: if the women don’t find ya handsome, they should at least find ya handy…
