PPTV directional sound beam OLED smart TV

At present, the TV sound system is non-directional. As soon as the TV is turned on, the sound will fill the whole house. Due to the different sound insulation effect of the wall, the next room and even the neighbors will be disturbed. Even if the volume is turned down, it will interfere with other members of the family who need a quiet environment. Therefore, people watching TV will be very unhappy and cannot experience a good viewing experience.


Starting from the user's experience, we reduce the troubles of users watching TV to disturb their families and others. The TV sound bully system adopts a new generation of directional sound technology to make the sound spread like a light beam. Based on the principle of parametric array, the sound bully system modulates the audio signal to the ultrasonic signal, and generates a sound with high directivity through the self-demodulation of the unique nonlinear effect of the ultrasonic wave, thus realizing the spatial distribution control and sound source position control of the sound wave propagation in the air. If the traditional speaker's sound method is like a light bulb emitting light to transmit in all directions, then a speaker with directional sound is similar to a spotlight, emitting a beam of directional sound waves. Therefore, PPTV directional sound beam smart TV will not add any noise to the room, and effectively improve the sound environment quality in the space.
