What is a Super Directional Loudspeaker?

A Super Directional Loudspeaker can send sound to the place which you want to send by emitting sound like a laser. 
Since ultrasonic waves send sound, the straightness of sound is excellent. 
Almost no sound can be heard from the back or the sides of the loudspeaker.
