Directional propagation of acoustic wave is a new technique to control the direction of sound propagation. It converts the audio signal into AM (amplitude modulated) ultrasonic signal, and uses the nonlinear effect of air in the process of sound propagation to restore the original audio signal, and then produces a sound beam with strong directivity.

Directional high-intensity sound equipment is a type of long-distance transmission equipment of high-power acoustic wave, which can realize long-distance propaganda, broadcasting, guiding, warning, deterrence, rejection and evacuation of objects in specific target area by transmitting high-energy acoustic wave.

Characteristics

→  Strong Directivity: The directional acoustic wave equipment controls the sound transmitting direction within about ±15°. It is like a flashlight beam with strong directivity.

→  Long Transmission Distance: The transmission can meet the needs of long-distance broadcast communication, ship-to-shippropaganda, warning, etc.

→  High Sound Quality: The directional acoustic wave transmits sound which has high quality in clarity, intensity, and identification.

→  Adjustable Beam: The sound beam can be adjusted within the range of ±7.5°~±15°.

→  Adjustable Volume：The adjusting of the volume of transmitting through controller is helpful to realize the function of communication/warning/ evacuation respectively.
