Features:

Directional speakers use an array of piezoelectric ultrasonic transducers to produce asound beam which points to specific direction like a laser beam. These smallultrasonic transducers are capable of producing sound at high frequencies whichlead to a narrow beam of sound wave produced by devices, and the ultrasonicbeam can only be heard along a very specific path, just like a spotlight.
