Advantages of the Ultrasonic Directional Speaker: 1. Strong Directionality: Achieves the best voice control point and maximum reduction in noise pollution. 2. Easy Installation: Can be installed at any angle. Ultrasonic waves are only a few millimeters in length. They are much smaller than traditional speakers and can produce a narrow, nearly linear beam of sound. Ultrasonic wave directional loudspeakers can travel through the air like a flashlight beam, controlling the sound in a particular area. Sound can be enhanced in a specific area and diminished everywhere else. Z
