I usually pack around an iPhone for convenience, and find that the built in speaker is often handy for some quiet music as I write or code in a few places. In fact, as I write this, I have it playing a little Chopin to fill the air. But unless the room is really quiet to start with, the iPhone's internal speaker is simply not going to cut it.
But that is where the MegaPhone by en&is design comes in. True to its name, the MegaPhone is a mechanical amplifier for your iPhone and (I think) iOS Touch devices. To use it, you simply place your device at the small end, and sound comes out at the big end. While I have not seen one of these in person, the concept seems to be solid enough. The video below shows it in action, but as to how accurate the video is I cannot say.
Each MegaPhone (gotta love that name) is crafted by en&is, and the price reflects this. You can find a black or white version for 400 Euros, but a gold plated version will hit you up for 600 Euros. You can find more information at the en&is website.

Megaphone
A megaphone, speaking-trumpet, bullhorn, blowhorn, or loud hailer is a portable, usually hand-held, cone-shaped horn used to amplify a person’s voice or other sounds towards a targeted direction. This is accomplished by channelling the sound through the megaphone, which also serves to match the acoustic impedance of the voice cords to the air. The natural human voice tends to spread evenly in all directions, whereas when it is sent through a megaphone, the sound is concentrated in a given direction and the coupling of its energy to the air optimised, while if a listener is to the side, it is more difficult to hear what is being said.
