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.

How to use a Directional Loudspeaker
Each sound does not interfere with each other, and only the sound of the ad you are looking at is heard.
Sound can be transmitted only to the desired area, so effective information can be provided.
The announcement can be delivered to those who need attention without being assimilated to ambient noise.
Sound can be delivered only to where you want without noise damage to the surrounding areas.
