The system, dubbed flat, flexible loudspeaker (FFL), started life as a piece of tin foil and some baking paper.
These materials were first used to produce sound by Warwick University professor Dr Duncan Billson.
It provided proof of concept and since then the system has developed into a complex set of flexible laminates made up of different conducting and insulating polymers.
Traditional speakers work by converting an electric signal into sound. What makes the FFL different from existing speakers is that when stimulated by an electrical signal it moves air as a bulk mass rather than from a point source.
This means sound is more evenly distributed around a room without the blasting effect of traditional systems.
