The internal circuitry of the Soundlazer is very complex. A digital signal processor fine tunes the audio before sending it to the oscillator which produces an electrical signal that turns on and off forty thousand times per second. This 40KHZ signal is amplified and sent to the 39 ultrasonic emitters that produce the directional […]
Once the case design was finished in Solidworks, a 3D printed ABS plastic test part was made to verify that everything fit correctly. After a few minor changes, the aluminum case was machined.

This is a good explanation of how parametric speakers work and a few interesting uses. The Soundlazer can do all these things and more.
