Gramophone-style Acoustic Amplifier for iPhone

Using no electricity, the Aircurve uses a gramophone-style acoustic chamber to amplifier an iPhone. Will it work on Greg's iPod and allow his child to listen to Yo Yo Ma? Don't know, but it sure is looks better than Greg's iPod in the cereal bowl.

Too low tech for you? Check out Ross' homebrew chip amplifier.
