Directional speakers use an array ofpiezoelectric ultrasonic transducers to produce a sound beam which points tospecific direction like a laser beam. These small ultrasonic transducers arecapable of producing sound at high frequencies which lead to a narrow beam ofsound wave produced by devices, and the ultrasonic beam can only be heard alonga very specific path, just like a spotlight.
