Made 2/22/09: This is a volume booster for my iPhone. It is made from a plastic cup with a slot cut into it. The iPhone slides into the slot and the cup acts as an acoustic resonator for the iPhone’s built-in speaker. I attached a pencil to it for support so it could sit in the basket of a wire shelf in my bathroom. Then, I’d be able to hear music (or incoming phone calls) from my phone over the sound of the running shower water.
