The I-MU Vibro Speaker claims to turn just about any hard, flat surface into external speakers for your iPod or compatible mp3 player. It does this with ‘patented super-energy crystals’. Wow. That’s a new one. The device will presumably give you a very loud desk. No comment on the shape and how this device could potentially be misused in other situations. If you’re a big believer in ‘patented super-energy crystals’, why not give it a go for £29.99.
