#2My mind immediately goes to VR – imagine how much more immersive that would be!

Are multiple pixels somehow combined to reproduce low frequencies?

#5Would the vibration be detectable via touch?
It would be wild to integrate this into haptics

#6This is impressive. Though perhaps not very useful. Humans (and animals in general) are quite bad at precisely locating sound anyway. We only have two input channels, the right and the left ear, and any location information comes from a signal difference (loudness usually) between the two.

Good point, piezos do also generate voltages when deformed, so this could conceivably be run in reverse... Microphone arrays are already used for directional sound detection, so this could have fun implications for that application given the claimed density of microphones.

Technically yes, piezo cells are reversible, just like about anything that can be used to emit sound. You can use the array for programmable directionality as well.

Localization of sound is primarily based on the time difference between the ears. Localization is also pretty precise, to within a few degrees under good conditions.

#10This is a long shot but anyone know if there's an audio recording of the sound the display produced? Curious
