Directional Speaker Ultrasonic Audio Speakers For Home and Museum

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
Product Parameters

What applications can directional sound be used in?
Museums and Exhibits: Providing targeted audio information to visitors without disturbing others nearby
Retail Advertising: Delivering personalized audio messages to specific areas within a store
Trade Shows: Facilitating private audio presentations in large event spaces without the need for individual speakers
Digital Signage: Enhancing interactive displays by directing sound to specific viewing zones
Public Spaces: Broadcasting announcements or information in crowded areas without disturbing the entire space
Gaming: Enhancing gaming experiences by directing in-game audio to specific player locations
Advertising Displays: Focusing audio on specific points of interest within an advertising spaceSound shower mode
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.
