[SFDXA] MIT Engineers Develop a Flexible, Paper-Thin Loudspeaker

[Bill]

MIT researchers have developed an ultrathin material that can turn any 
rigid surface into a high-quality audio speaker 
<https://scitechdaily.com/mit-engineers-develop-a-flexible-paper-thin-loudspeaker/>. 
The team showed off a hand-sized speaker that weighs about as much as a 
dime, and uses far less energy than a traditional loudspeaker. One 
possible application is noise cancellation in noisy environments, such 
as an airplane cockpit.
