May, 2016—This is my second attempt at making a passive audio amplifier for smartphones. With this one the sound loops around in an ever-expanding channel until it exits out the front. I also configured the slot so that any cell phone could use this one, regardless of which side of the bottom the speaker is. But with that flexibility comes a slightly reduced sound volume.

So this was another band saw box blank re-purposed into a passive sound amplifier for smartphones.

Too bad you didn’t get a pic preassembly. How does it perform?

I do like the design you’ve came up with here and the other one.
