Here’s my version of the passive cell phone amplifier. I wanted to try something a little different.

I like how it sounds. It’s sound is hard to describe, it adds some depth, similar to reverb. It’s not that much louder, but I can hear it across the room better than without it. Anything helps the little speaker built into the phone.

Building it was trial and error. I intended for it to have a bottom, but it sounds better without it. I did put some small cushioned feet on it, lifting it about 1/8”.

I used 1/8” baltic birch ply fitted into grooves in the corner posts. The frame that supports the phone is a tight fit, then CA glued in place.

I tried my daughters Samsung phone in it. It would probably fit if I removed the case, it’s a little too thick. Oh well, I guess I have to keep it for myself. I have some ideas floating around in my head for some different ways to do it.

4 & 1/2” x 4 & 1/2” x 7” bb ply and walnut. BLO.

A very impressive piece of woodworking I must say, and along with an acoustic engineer in the making.

Can you please add an audio clip?

Very pretty box, Nicely done Sir ! I remember emceeing a talent show at a mountain festival in Hyden Kentucky way back. An elderly woman was playing a dulcimer beautifully but couldn’t be heard well by the outdoor audience. I offered to set up a mike above her playing area, but she refused and signaled two burly guys and they brought an old wooden dresser up on stage. She removed the two upper drawers (of four) turned the other two drawers upside down & replaced them placed her duclimer on top, stood on a pice of plywood covering the pair of removed drawers. After getting comfortable she began to strum….and then set out into several beautiful old ballads…of course the folks on the crest of the hill 100’ away began to clap and whistle…. she could be heard and of course walked away with 1st prize in both hammered and hand strummed dulcimer category…. Goodon’ya hairy !
