MIT Researchers develop a paper-thin loudspeaker

@fiesta75 A tiny Tekton then?
Got to admit, it’s intriguing. the domes are so small, it’s more like the paper-thin substrate itself vibrates rather than lots of transducers themselves creating the sound.

Take that, Tekton tweeters!

Rather than having the entire material vibrate, their design relies on tiny domes on a thin layer of piezoelectric material which each vibrate individually. These domes, each only a few hair-widths across, are surrounded by spacer layers on the top and bottom of the film that protect them from the mounting surface while still enabling them to vibrate freely.
