Was at Harold Washington Library today at the printer guild exhibit. They have this hyper directional speaker in the corner. Makes sense for its purpose.
I wonder what is in there though. It's so shallow. I get the wide baffle hut wonder what thin driver would be in there. A planar? I really want to take it apart but there's a lot of security here....
It's SUPER loud when you are directly under it. Turned up too high I think
Anyways, thought it was interesting

I saw the patent many years ago, if I recall correctly it is based in two sources of high freq. above human hearing and the audio input modulates one of them.
The difference tones are the audio stream (heterodyne process?).

Now I also recall other technology I saw at that time, the panels were made with a matrix of many small speakers and then they used DSP to create beamformers.
Watched the vid. This is exactly how it behaved. Pretty sure this is it. So cool, thanks for linking the vid
