March, 2017—A friend liked an earlier model so he asked for two for his daughters. They both amplify the sound playing on a smartphone. That’s an iPhone in the photos. The smaller amplifier is made of a piece of hardwood from a log that a friend dropped off. The larger one is pine. When it comes to the megaphone acoustics, size does matter. Both are finished with a light stain and water-based satin poly.

The primary tool on these is the band saw. The router is used to make the slot for the phone, and to round-over some of the edges. These are fun and I’m getting smarter on each one.

Those are very cool Art. I’ll bet they do boost the sound nicely.

Very cool. The hardwood one has nice figuring.

I know these have been made before, but are there principles to the shape/size for maximum performance? Or is it a trial and error process?

Great job. IS there anything inside the horn to keep the phone from actually sitting down against the bottom and blocking the phone speaker?

There is nothing but a flat bottom. You are correct, phones with bottom speakers will perform better if they are propped up, maybe a quarter inch. An easy way to do that could be to drill a small hole for a dowel in the center of the bottom of the slot, and glue in a dowel that would stick out of the hole a quarter-inch.

Yes, I’m sure there are acoustical principles that could be considered for maximum audio performance. Companies like BOSE pride themselves on optimizing great sound from small spaces. These wood boxes are no more effective than a megaphone would be. The larger the megaphone, the larger the sound. In a wood project I think we need to find a balance between acoustics and appearance.
