£500 Phone + £0 Speaker = Logical?

I got an IPHONE!! And its possible that I am slightly obsessed, well slightly more than slightly. So I saw this design for an iPod speaker made out of a toilet roll I figured I had nothing to lose by trying it! Except maybe half an hour and some dignity when my family called me a cheapskate.

I mean it makes sense, sound is caused by the displacement of air so if you displace more air, it sounds louder right? I built this and after playing around with the drawing pin positions a bit I managed to get it to stand up on its own.

When on a quiet volume the tube did make the music louder but at the highest possible volume the tube made no noticeable difference.

I then found this design and it looked like this:

It was so fiddly I nearly gave up twice but I stuck with it. I ended up sacrificing presentation for stabilty which was a difficult but inevitable choice. This design is more portable and looks pretty cool but doesn't really work much better, probably a little worse. So now I know.
