Wireless Mini Ultrasonic Directional Sound Speaker

                              Mini desktop and wall mounted ultrasonic Directional sound SpeakerDescription: 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 Description Features:Play with Bluetooth 5.0;Comes with Audio play,U-disk, TF card display;Better sound experience,Perfect Stereo;More Convenient to change volume with Remote control;Infrared sensor control(Silent model,Play from start, Cycle display);Virtual sound source: the effect of object sound produced by object reflection;Super-thin features: Super-thin transducer unit gives the system an super-thin thickness;Super directivity: ultra-narrow beam angle to avoid mutual interference of different sound;Low distortion: pre-processing algorithm reduces distortion to meet the needs of ordinary voice and music;Super-long distance: the sound intensity doesn't attenuate with the distance spherical surface, increasing the propagation distance.Model No.G-15G-16G-19Size:Φ220*230mmΦ200*316/117mm985*985*35mmN.W:gggMaterial:acrylicMetalAluminium alloySPL:80±5dB@1kHz/1M85dB@1kHz/1M80dB@1kHz/1MFrequency Range400Hz-10kHz400Hz-10kHz400Hz-10kHzTransmisionDistance:
