Using Tables as Speakers

James writes "At CeBIT, Olympia has been showing off its Soundbug - a gadget that can turn almost any flat surface into a soundboard. It's only gonna cost £29.99 (around $45, i guess), but it sounds like there's some seriously cool science behind it."

Practical joke ability

[Erich]

This has great potential in the realm of practical jokes.

Imagine sucking this to the underside of someone's desk way back in the knee well. Then attach it to a radio and a timer device that will randomly turn on the radio for a few seconds every few hours.

Imagine attaching this to the door of the person who was making loud, annoying noises with a POTAS whilst you were trying to sleep, and waking them up when you have to go to your 8:00 class!

The possibilities for this device are truely limitless.

Re:Desk for a speaker?

[IainHere]

Well, obviously damping the vibrations (with books etc) would decrease the volume, but it's not true that you wouldn't be able to achieve stereo sound with a single vibrating body. Different parts of your desk don't have to vibrate in phase or at the same frequency unless it is infinitely stiff, which it isn't.
