At this year's CES show, a TV that Sony showed off is quite eye-catching. The reason why it is so compelling is its unique vocal mechanism. This OLED TV model XBR-A1E Bravia does not have any external speakers, stereos, etc., but it can generate sounds on the screen itself. Many people are very curious about this subversive design. Let Xiaobian take everyone to understand what the screen sound mechanism is.
In fact, the cause of the sound is very simple, and the vibration of all things can create sound. Whether it is the vibration of a string or the vibration of a football striking the ground, it can be converted into sound waves and received by human ears. In an ordinary LED television, an acoustic signal converted from an electrical signal needs to be transmitted to the user through vibration. Since the internal structure of the backlight television needs to be complex, the acoustic wave can only be released through a speaker and other devices.
However, in OLED TVs, since the organic light-emitting diode material can emit light by itself, no backlight is required. Therefore, the reflector, diffusion sheet, diffusion plate, back plate, etc. are also unnecessary in construction, and the structure is light and thin. This gives OLED TVs another advantage, which is the ability to send sound waves directly through the vibration of the screen. In fact, LED TVs can vibrate, but because the internal structure is too complex, vibration cannot be completely transmitted to the outermost layer.
OLED TV can be sounded through the screen, in addition to the advantages of the OLED body itself, in fact, it is also the vibration of the "vibrator." Through vibration of the exciter, the OLED screen immediately vibrates to form sound waves. Therefore, for self-voiced television, the entire screen is equivalent to a TV speaker.
After understanding the relevant theories, will everyone think that this is just a “straw†that has been added to attract consumers? In fact, the screen sound technology has an impact on the TV structure, on-the-spot experience and other aspects. First of all, from the structural point of view, OLED TVs do not need a backlight source, so they have a very slim appearance, and they can be upgraded to lightweight ones without audio equipment. LG's "Wallpaper TV" uses such a design, which is very slim from top to bottom.
For the user, the sound of the ordinary TV is transmitted from the speaker, but the location of the speaker is not the front of the television picture, but the bottom or side. When actually watching TV, the sound is not transmitted from the front. However, OLED TVs with screen sound technology can allow sounds to be transmitted directly from the front and have a more immersive experience.
Actually, this technology is not as mysterious as everybody thinks. The reason why we can use the sound of the screen is still the vibration that we know well. But as to whether or not the television with this technology should be started, the benevolent sees the person, and the wise see wisdom.
