Principle of Operate:
Long Range Acoustic Device work principle like Antenna array, arrangemulti acoustic unit which can generate high power acoustic on a round flatpanel, it make up a surface acoustic base array, and use the acousticsupraposition principle to focusing and direct the voice . the Acousticunit use electroacoustical transducer, and the character is bigpower ,convert efficiency high, small dimension, and with small heatemitting.signal source and amplify circuit control the phase coherentemitter, and based on the supraposition principle, the large acreagetransducer array generate narrow acoustic beam, so that the acoustic powersource directed emitting.
Product Specification:
Highly directional communication at 1000/2000/4000 meterCarry and install easy,Can quickly install in everywhereSupport Microphone.MP3 etc multi audio input method, and can broadcastvarious kinds life like voice.One operator is enough and the back of product is safety areaSuitable for all weather.
