Doing this tomorrow Few issues though 1. Wouldnt the bubble muffle the sound of the speaker? if so, why not add holes... 2. what do you do with a speaker that only puts out as much as one thats mounted to the ear... what would be amazing, would be if you would create a fullsize version of this, it would look great on a desk, on the road, ect... I might make it, who knows In the mean time, great idea, fast, fun, and useful in the end Awesome.

The reason you can normally only hear tinny sounds from a pair of tiny speakers is because the sound from both sides cancel each other. Nothing stops the air being pushed from one side from meeting the air being pulled by the other side, and so all but the very highest frequencies cancel. The bubble isolates one side of the speaker, allowing the other side to send out sound without being canceled. That's why -any- speaker just sitting there, not in a box or a plate, sounds tinny. Cancellation is worse for the lower frequencies. Try it with your headphones without even tearing them apart. Make a cylinder with your hand and hold one earphone at one end of that cylinder. Or find a cardboard or plastic cylinder that is about the same size as your headphone and put it at one end. Suddenly it is loud and with some low frequencies! I know all this works because I started doing this long, long ago with mousse can tops.

The bubble is around the back side, creating an acoustic suspension chamber. This actually reinforces certain frequencies based on the volume of the chamber, resonance of the driver (headphone speaker) and other factors (go read about designing speaker cabinets). Holes would make this a ported enclosure which has different dynamics.

first-thanks for the great comments, make my day better. now onto the issues, i wasn't very concerned with the sound quality because these were designed to look cool they where attached in splitter with my regular speakers. as your idea of making a larger version of these, i think that would be awesome...'cept one problem...i don't speakers that big and i don't have bubbles that big.
