I have been playing with making speaker boxes for my phone. I like to listen to music when I am at craft shows. Battery powered speakers didn’t work well for me. I had my phone in one of these boxes playing music one day and a fellow crafter asked if I could make a bigger box for her Kindle so she could hear movies better. I can relate to that issue. Another person wanted one also. I made 4 and sent each of the ladies one to try. My wife got the first one for her ipad. My sister got the other one for her Nook. I made 10 more with a lot of different woods, trying to put some kind of ‘tone’ wood as the back panel.. A friend who makes mandolins and ukuleles got one made of different types of Redwood. He is going to play around with it. They do increase the sound quite a lot. The different woods, and the different positions the little blocks of wood give, can alter the tone or pitch of the sound and the little pieces of wood give different viewing angles. I rounded the sides to give an inside curve to help project the sound better. Notice in the first picture that I have a ‘photo’ of my wife’s ipad. I couldn’t take her actual ipad, so I bought a kindle for future show demonstrations. My phone works okay, but the larger mass of the ipad changes the sound. The devices speaker needs to be positioned so it is bouncing sound off of the back wall. I made my phone box so it has a hole for recharging. The wood for my phone speaker is Ambrosia Maple. The second picture shows a box of Spalted Maple and Osage Orange. The first box is Eastern Red Cedar and Red Gum Eucalyptus. I used Watco Natural Danish Oil for the first 4 and then sprayed on a lot of coats of rattle can Poly. The last 10 only have the Watco.

Really cool boxes! The one with your phone looks like the speaker of the phone is aiming to the front. Do you turn it around?

Uncle Stumpy. The speaker on the phone is on the back in the lower corner. The sound bounces off the back wall. On my newer phone, the speaker is on the bottom edge. I kept the old phone to play music.
I have no issues with someone using my ideas as inspiration for their own version. Enjoy

Would you say that the harder the wood, the better it would reflect the sound and that softer woods would tend to absorb more of the sound?

Very nice. Love the wood you used with the iPhone (last pic). I am sure these will be great sellers for you.

Thanks for the comments. George, I don’t know a lot about music, but I thumped on each one to get some idea of the sound. I would think that the more dense the wood, the more sound would bounce off. I have been around power tools for 35 years so my hearing is not great for small differences. I made the back panels out of different woods- Douglas fir, redwood, Osage orange, walnut, and Myrtlewood to see the difference in sound. I made these panels 1/4” which may be to thick. I will have to keep experimenting.
