Product Description

Description: Ultrasonic wavelength is only a few millimeters, much smaller than the speaker, thus can produce

nearly linear narrow beam. Ultrasonic wave directional loudspeaker can be like a flashlight beam

directional spread in the air, can control the sound waves in a particular area, sound is very big, in the

specified area out of the area, there would be little voice, not even.

Advantages of Ultrasonic Directional Speaker

A. Strong directivity, achieve the best point to control the voice and maximum reduce noise pollution.

B. Easy installation, can be installed at any Angle

Sound shower mode

Ideally, the directional speaker should be mounted on the ceiling, facing the floor. This creates a typical "sound-shower" situation, making the sound audible only at one spot in the room, while enabling it to be heard by people - of all heights - at the same spot. The sound-shower mode is also the best solution to minimize reflections of the sound and its audibility at different locations around the room. The sound starts to travel from the ceiling, bounces off the floor and is reflected back to the same spot at the ceiling, and so on.

Virtual speaker mode

A very interesting mounting situation is the "Virtual speaker mode", where the speaker is not pointing directly towards the user. Instead, the speaker is pointing towards the digital sign, (or any other object that you want to draw attention to, by using directional sound) from which the sound beam bounces and arrives at the user indirectly. This situation makes it appear as if the sound originates from the object that it is being reflected from. The actual sound source remains hidden and is not noticed by the user.
