Make a Hi-Fi Speaker With a Paper Plate

Here's a fun little project that can lead to all sorts of interesting experiments and design ideas.
Jose Pino has managed to design a simple speaker that you can build from a couple of bucks worth of components that you likely already have lying around the house. The whole thing can be done in about an hour (not including time for the glue to dry), perfect for a lab or study hall period.

You follow his step-by-step instructions online here, but the fun part would be to see if you couldn't really begin to up the fidelity by working on some acoustics and cavity resonance, perhaps trying some other materials.....


Start here, and see what you can imagine!
