The operation of a directional speaker is based on the parametric array principle. The audio signal is modulated onto the ultrasonic wave, and then self-demodulated by the nonlinearity of ultrasound. The ultrasound has much higher directivity than regular audible sound due to shorter wavelengths, which enables this speaker to control the spacial distribution of the propagating acoustic wave.
