Ultrasound Could Replace Proximity Sensors In Phones
This is neat.
My only question is whether or not smartphone speakers are currently capable of producing ultrasound waves (and whether the microphone is capable of picking them up). Like. How does it work? Normally specialized equipment is needed. Does this mean we can also start to do normal ultrasound scans using a phone?
As far as I'm aware, normal smartphone mics and speakers have limited frequency output and input (based on my own tests as an audiophile and musician), so... How does this work?
