iMu Vibrating Speaker – less rude than it sounds
Although the name conjures up memories of the Ohmibod, the iMu is totally safe for work. So long as people don’t get annoyed by you turning the big conference room table into a huge speaker anyway. That’s right – the iMu claims to turn any hard, flat surface into a speaker.
How does it work? Well, it turns music signal into vibrations via a compound called Terfenol-D – developed by the US Navy. Place the Terfenol in an aluminium case, wrap a coil round it and pass a current through, and it’ll vibrate with the current – playing your songs.
The frequency response isn’t great – 70Hz to 30Hkz – but you’ll get 30W out of this thing. I’ve asked if we can get one in to see what it sounds like in person, and how loud you can get it without shattering whatever you’re vibrating. That could be fun. If you’re already convinced, then it’s £50 and available now.

Clearly some surfaces make better speakers than others.
Let’s hope you don’t test it in an all glass house
