Engineers develop a flexible paper-thin loudspeaker

New design has the potential to turn any surface into a low-power, high-quality audio source.

MIT researchers have developed an ultrathin loudspeaker that can turn any rigid surface into a high-quality, active audio source. The straightforward fabrication process they introduced can enable the thin-film devices to be produced at scale. Credit: Felice Frankel
