Civilian Directional Acoustic Device Parametric Speaker Ultrasonic Audio Speaker

Mini Audio Spotlight Directional Speaker System
Directional speaker is a kind of speaker designed for individuals to focus sound to the head without disturbing other people around.It is so funny that you listen to music without earphones in loud sound and no one else can hear what you are listening or directly send message to someone’s head keeping others unalarmed.
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
6. Indoor and outdoor advertising
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.
