Introduction
Specification

DSS1418 is a directional active speaker system. As the ultrasonic wavelength is only a few millimeters, much smaller than that of the speaker, it can produce a nearly linear, narrow beam. Ultrasonic wave directional loudspeaker can realize directional spreading of sound in the air just like a flashlight beam, and control the sound waves spreading in a specified area, so that the area has a large sound, while other areas have smaller sound or even no sound.
