G-19 Mini Audio Directional Speaker System

Directional speakers use an array of piezoelectric ultrasonic transducers to produce a sound beam which points to specific direction like a laser beam. These small ultrasonic transducers are capable of producing sound at high frequencies which lead to a narrow beam of sound wave produced by devices, and the ultrasonic beam can only be heard along a very specific path, just like a spotlight.

Features:
Compact size and light weight
High directivity
Multiple audio sources can be played at one place and at same time without interference each other
Noise free, only heard within specific angles, no interference, no noise around
Refraction, can be reflected by flat surface, virtual audio player available
Easy to install and simple maintenance

Directional speakers are also widely used in retail stores, exhibits, museums and other crowded places where you get the description of a product or an art in a museum or showroom by these speakers. They produce sound in specific direction, so you must be in the right place to hear the sound and no one else is hearing it except you. This technology has vast applications in various fields.
1. Museums
2. Libraries
3. Trade Shows
4. Offices
5. Shopping Malls
