"Engineers at MIT have created paper-thin speakers using a plastic film and a piezoelectric layer embossed with tiny domes.
"These sheet speakers could potentially be applied to any surface for sound output or input: think surround sound or noise cancellation in aircraft. The technology also has potential for ultrasound imaging and echolocation, among other possibilities.
"The work is described in a paper published recently in the journal IEEE Transactions on Industrial Electronics, "An Ultra-Thin Flexible Loudspeaker Based on a Piezoelectric Micro-Dome Array.""

The dumbed-down article needs qualification but who cares? It may find a niche.
