Soundbug is a small device that can turn nearly any flat surface into a soundboard. The Soundbug was developed from Olympia in partnership with Newlands Scientific, a commercial research company that was spun off from Hull University.

The Soundbug transmits the sound to the flat surface by way of a small piece of Terfenol-D, which is a mixture of rare earth metals and iron. This substance is placed within an aluminum case, around which is wrapped a coil. Passing electricity through the coil causes the piece of Terfonal to slightly expand, resulting in a force of 400 pounds, explained Newlands Scientific managing director Brian Smith.

Once attached to a flat surface, Soundbug will transmit electronic signals into mechanical energy, causing the flat surface to vibrate and broadcast the sound.
