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
