Now TVs are getting thinner and thinner but the sound quality is poor and the solution

Do you still remember the big head TV, the big head monitor? Do you remember the feeling that several people needed to lift downstairs together for each TV repair? Do not know when to start, ultra-thin has become a major standard for people's aesthetics, the television industry has undergone a qualitative leap, ultra-thin, large screen, high intelligence has become the trend of flat-panel TVs. With the advancement of the LCD display of the upstream core technology, some televisions have already been thinner than smartphones (connected: "Made in China" shocked the world that domestic TV is even thinner than the iphone 8).

Thinning and thinning televisions have sacrificed their own conditions for ultra-thin, among which the speaker equipment is the most prominent.

Spatial limitations create major problems

The performance of the horn on the sound is closely related to the size of the horn and the size of the speaker. In a confined space, there is not enough frequency for the sound to radiate within the wall, and the sound is not full.

At present, ultra-thin TVs are difficult to have a "good voice," and CRT TVs are based on the product characteristics of their own space. The selection of horns does not have these limitations of LCD TVs. Therefore, in general, its sound performance will be better than that of LCD TVs. The smaller the size of LCD TVs, the greater the restrictions on the performance of their sound.

Smart TV audio is now difficult to hear

Now the mainstream television speaker structure analysis

1: closed speaker (the simplest speaker mode, good bass analysis, but requires a large space)

2: Coupling cavity type speaker (distortion range is reduced compared to closed, greater power)

3: folding horn speaker (best for home speakers, the effect is better than most structures)

4: passive radiation speaker (bass preferred, very strong)

With the current technology, ultra-thin TVs are still unable to solve the problem of lack of self-contained audio. However, many manufacturers at this year's CES 2017 exhibition also aimed at this issue and launched their own products to deal with such issues: a panoramic whispering gallery.

The emergence of the whispering gallery saved the ultra-thin TV

The whispering gallery, the English name Soundbar, was originally called “sound bar” as an emerging speaker product. This is a product that integrates multi-channel speakers and power amplifiers into an elongated box, basically retaining the traditional “amplifier”. + Speakers feature that can simulate multi-channel home theater audio.

Its main features are simple installation, simple connection, simple operation, and very space-saving.

Concerned about the development of audio over the past few years should have heard of Dolby Atoms or panoramic sound, but what exactly is combined with the echo wall? What is the difference with conventional panoramic sound systems? In addition, as a consumer should buy one? Let's briefly talk about this newly emerged panoramic sound echo wall.

What is panoramic sound?

Popular Science: What Do Dolby Vision and Dolby Audio Are Common in TV and Movies?

In layman's terms, Dolby Pan sound allows the sound to flow in a 3D space "above and around the head," and all sound effects can be precisely deployed and moved anywhere in the room, including the top of the head. Therefore, the panoramic sound channel arrangement is completely unrestricted. However, Dolby panoramic sound suitable for home use is usually a combination of 11 channel speakers and 2 subwoofer channels, and at least 5.1.2. The configuration is "left center, right front, 3 + 2 surround + 1 subwoofer + 2 top mounts" configuration.

What's different about Dolby's panoramic echo wall?

Dolby Panorama sound "top audio" can be achieved through the overhead speaker (at least 2 speakers in the home), enhance the sense of reality and further expand the range of sound effects. However, Dolby's fixed "top audio" can also be achieved through the use of special speakers, which are top-hat audio effects by sending sound effects up the roof and then "reflecting" down.

The whispering echo sound bar with Dolby Surround sound utilizes the principle of “reflection”. By designing a loudspeaker dedicated to transmitting sound upwards, it can be reflected from the ceiling to create a “sticky sound”.

At present, most of the panoramic sound whispering walls use the settings of the lowest two “reflector” channels to enhance overall performance, but still have plug-and-play settings that are quietly integrated into the room décor.
