Can anyone explain how "tiny membranes that vibrate at an ultrasonic frequency" is able to produce "AirJet’s 1750 pascals of backpressure" which is "more than 10 times the suction force of a high-end notebook fan"?
I understand how you could have a bunch of membranes that vibrate ultrasonically -- it's basically an array of miniaturized audio speakers. What I don't understand is how any localized oscillation of air gets transformed into massive, consistent air suction in a single direction.
