It's probably better to read about what this little gizmo does before you look at the pictures, otherwise you may forgiven for thinking that the I-MU Vibro was some sort of, ahem, 'personal stimulation product'. Just like a good spy novel or a run around the block...

i-MU's Vibro: you hum it, I'll play it

But the I-MU Vibro's looks are deceiving - it's actually the latest in a rapidly expanding range of rigs designed to turn any flat surface into a loudspeaker.

This variant of the technology uses something called Terfenol-D placed inside an aluminium case with a coil wrapped around it. When electricity is passed through it the coil, its expands and create a pressure equivalent to 400lbs.

Sitting the 8cm wide, 12cm high, 8cm deep device on a flat surface then means that it will convert electronic signals into mechanical energy, which causes the surface to shake, rattle and - we'd imagine - roll, therefore giving you a music broadcaster of up to 30W.

The joystick-shaped device is battery powered and connects straight to your music source. It's also available in a range of colours, but sadly not sizes, tastes or textures.

The I-MU Vibro is available now and retails for around £50 (€73/$100).
