The TV is becoming thinner and thinner, and it can already be thinned into a piece of paper and hung on the wall; the picture quality is getting better and better. After the popularization of 4K, 8K has come out; but what about sound quality? Many people complained that it was less than that old heavy TV set years ago or even more than ten years ago.
What makes TV's sound quality down to the "listen to the sound" situation? All this must start with the structural principles of television audio.
The incommensurable battle between thinness and sound quality Old-fashioned TVs are large, equipped with louder power and volume, and can ensure sufficient sound volume and low frequency.
The appearance of a reversed-phase speaker makes it possible for a small volume to exhibit good bass. However, with the development of ultra-slim TVs, the phase-resolved speakers still cannot meet the requirements of the thickness of the TV on the volume of the speakers, and naturally the bass effect is greatly reduced.
As a result, many ultra-thin TVs began to "curve the country" and abandoned the built-in speakers to use the external Soundbar. This greatly increases the number and power of the horns, ensures a balanced sound quality performance for high, medium and low bands, and at the cost of destroying the integrity of the TV. The additional cables make the wiring more cumbersome. At the same time, the combination of sound and picture The effect was also discounted.
So, how to break through the contradiction between volume and sound quality? Hisense NU7700 TV is the first to solve this problem. This TV is equipped with Hisense's unique patented technology - known as "Airborne Sound Field" technology that subverts the 60-year history of TV audio. Its greatest feature is the subwoofer's low-60Hz bass performance. .
So, Hisense NU7700 is how to achieve super bass performance? How does it actually feel? And, as the newly released ULED TV, is the picture quality still worth the wait? This is the answer you want to solve in this evaluation.
"Comprehensive screen" not only senses that the mobile phone industry is now beginning to popularize a word, which is called "full screen." Refers to the mobile phone screen almost occupies the majority of the front of the phone, accounting for usually more than 80%. And this Taiwan Hisense NU7700 screen ratio, even as high as 96%, simply rolling iPhone X, millet MIX and other full screen mobile phone.
The "full screen" view benefits from the use of the Hisense NU7700 with a metal frame of only 2mm. Even with the addition of the BM area, it does not reach 1cm, minimizing the visual disturbance to the front. At the same time, the thinnest part of the body is only 8.9mm
For positioning the high-end ULED series, Hisense is obviously willing to work hard on the materials used in the work. This NU7700, where it can use metal, will never use plastic, and the benefit it brings is naturally a substantial increase in texture. CNC drilling, ceramic sand processing, metal integration, high-end products like no less technical process.
The backboard uses a metal-integrated design that is simple enough without a single screw. Therefore, a friend who likes to disassemble should pay attention, and the backplane part is very difficult to recover. Interface, NU7700 provides two HDMI interfaces (one of which supports ARC), two USB interfaces (one of which is USB3.0), an RJ-45 network interface, an audio and video input interface, a digital audio output Interface, a wired antenna input interface. All of these interfaces can be concealed using the cover, keeping the back neat and beautiful. On the network side, MU-MIMO technology and 2.4G and 5G dual-band Wi-Fi are supported. This makes it difficult to cause video stalling when there are many networking devices in the home.
The quality of the TV finally no longer "listen"
The high-frequency application of television in home entertainment mainly revolves around movies, games, and music. The quality of the sound directly determines the user's experience and immersion during use. When testing the sound part of Hisense NU7700, we kept the product as it was, and multimedia sources were all output from Hisense's native content platform. The actual listening reference was used to simulate the user's daily habits.
The sound mode of the Hisense NU7700 TV provides automatic, movie, music, sports, news, and DTS sounds. The automatic mode can be used normally. However, we found in the test that when you switch to the music mode, the bass effect will be significantly enhanced.
For example, when listening to Tsai Chin's "River", "River" is a more classic audition track. The main part is the beginning, the first drum is very powerful, followed by three voices, more crisp, and Bass's bass is stronger than the average TV, especially in the "music" mode. Wait until the first voice of Tsai Chin's mouth, can hear the voice is very clear, bright and prominent, plump and full without blunt. In general, the bass sounds calm and powerful, heavy and not muddy. Of course, there is still a gap compared to the external Soundbar, and it can be said to be the best in the built-in stereo.
In the game mode, the movie, DTS sound, or automatic mode can also be used. It is impressive in the performance of the sound effects of the game CG. In the horizon-zero light, the sound effect during the fight is thick and full. Hierarchical sound characterization is also very obvious, bringing a sense of space that allows users to immerse themselves in the game.
With the concentration of home entertainment, sometimes some users choose to use TV to listen to music or watch some live recordings. After switching to music mode, the sound fullness is improved, especially the sound of medium and high frequencies is satisfactory, and the low frequency part is elastic. Full, especially in the performance of some R&B and soul music.
The wide color gamut fine tuning began with the introduction of the first generation of ULED TVs in 2014. Hisense has created a series of achievements in ULED TVs from the key elements of backlight, panel, and picture quality chip. For example, this NU7700 supports dynamic backlight multi-zone control technology, self-developed Hi-View Pro image quality engine, and Acer 4D color display technology that incorporates smart light technology.
The NU7700 still inherits the picture quality of ULED TVs - extremely accurate color reproduction. The non-wide color gamut LCD TVs will be lighter in color, less dense in color, and even a bit whitish, while those with a wide color gamut will be adjusted too brightly and look uncomfortable for a long time. The color appearance of the NU7700 is somewhere in between, and it is not too intense in the wide color gamut, and it is closer to reality.
LCD TVs with side-entry backlights are prone to dark edges in the middle. The NU7700 is praiseworthy for its light control performance. First, there is no obvious light leakage, and secondarily, the brightness uniformity is almost impeccable. From this picture of the moon, it can be seen that the dark part is especially deep, with no visible spots or even a bit of OLED black taste.
Continue to enlarge the screen to see the details of the highlighted part, and keep it more intact. The topography of the moon's surface can be seen clearly. At the junction of the moon and the night sky, even the uneven terrain can be clearly seen, and the details are quite outstanding.
The NU7700 also supports HDR and is the full HDR. The HDR function is automatically recognized and enabled when HDR source is played, and the non-HDR film source screen is also optimized, but it is far less powerful than the HDR source.
Not only movies, but even games have begun to support HDR. Hisense NU7700 built-in different modes are optional, in the HDR bright mode, the contrast ratio is stronger than the HDR movie mode, the color is more eye-catching, and the HDR standard mode is somewhere in between.
As a World Cup custom TV, the performance of the dynamic picture is an important factor influencing the watching of the ball. The Hisense NU7700 is equipped with the Motion Flow function, which is consistent with the principle of the MEMC function. Through smart detection, it evenly compensates for the missing part of the motion picture and achieves smooth motion picture.
We use the PS4 Pro to play this latest "Live Football 2018" to test the smoothness of the dynamic picture.
A close look at the player who was magnified at high speed, the pace is very clear and there is no ghosting. Even football flying at high speed has only a short, unobtrusive, slight smear. Such a dynamic performance is better than that of ordinary people who support MEMC. LCD TV's. Due to the excellent performance of the details and the low delay, it is appropriate to play sports games such as “Liveâ€.
Familiar VIDDA The fun video call Hisense NU7700 still carries the familiar VIDDA system. The difference is that it has added many World Cup elements. From the boot screen to the various themes, it tells you that this is a television for watching.
And in the process of experience is to find an interesting feature - video calls. In fact, TV version of QQ, you can make video calls between TV and TV, and TV and mobile phone.
We use the Logitech camera C670i built specifically for TV, with 1080P resolution, support for wide-angle effects, no need to install drivers, plug and play. After simple authorization on the mobile QQ, you can use the TV to video, and you can pick up the sound of the remote control.
In summary, Hisense NU7700 is still the familiar ULED TV, accurate color reproduction, excellent light control and familiar VIDDA system. The newly added "air sound field" technology has clearly enhanced the bass and brought the performance of ultra-thin LCD TVs to a new level. It is considered as a sound quality solution with both aesthetics and practicality.
With the World Cup approaching, the TV market will usher in the peak season. Hisense, as the "FIFA Official Designated TV," has already had a first-mover advantage in marketing. According to its official announcement, Hisense will serve the World Cup broadcast from a technical perspective. No doubt, Hisense TV terminals will benefit both from technology and content. This also brings better prospects for TVs like the NU7700. The rest is whether the official price of 55 inches 8999 yuan and 65 inches 13999 yuan is within your budget.

What makes TV's sound quality down to the "listen to the sound" situation? All this must start with the structural principles of television audio.
The incommensurable battle between thinness and sound quality Old-fashioned TVs are large, equipped with louder power and volume, and can ensure sufficient sound volume and low frequency.
Old-style TV audio
With the advancement of screen technology, LCD TVs have become the mainstream of the market, and TVs have bid farewell to the “big head†in pursuit of lighter and thinner. However, the sound of sound depends on the principle of sound vibration of the air, and it is impossible for the volume to be infinitely small. Therefore, the sound quality becomes the biggest victim of the thin and light TV. LCD TV audio
Most current mainstream TVs use an inverting speaker (also called a low-frequency radiation speaker), and an inverting hole (slot) is opened in the speaker panel. The sound in the box can be radiated to the outside. When the speaker is working, the sound waves radiated from the back radiate to the front after passing through the inverting tube, superimposing with the sound wave in front of the speaker, and then jointly radiating forward to enhance the low frequency effect. The appearance of a reversed-phase speaker makes it possible for a small volume to exhibit good bass. However, with the development of ultra-slim TVs, the phase-resolved speakers still cannot meet the requirements of the thickness of the TV on the volume of the speakers, and naturally the bass effect is greatly reduced.
As a result, many ultra-thin TVs began to "curve the country" and abandoned the built-in speakers to use the external Soundbar. This greatly increases the number and power of the horns, ensures a balanced sound quality performance for high, medium and low bands, and at the cost of destroying the integrity of the TV.

Speed ​​and Passion 7 clips
The surround sound of the movie part has always been the core of most TV sound optimization. The TV usually adopts a virtual surround program. The Hisense NU7700 provides movie mode and DTS sound for the movie in sound mode. The movie mode can provide wide sound field sound in dialogue and The effect of the sound level is obvious. After the DTS sound effect is enabled, based on the wide sound field, the details on the sound details are more exquisite, the high-frequency transition is natural, and the effect on the performance of the large dynamic sound effect is significant. Two 10W speakers
After the audition is over, let's talk about the bass implementation of the NU7700. Unlike the inverting speakers of ordinary TVs, the NU7700 uses a dual-mode resonant ultrasonically sealed sound box, which is a type of enclosed speaker. At the same time, in order to make full use of every inch of space to enhance the bass, Hisense NU7700 adds two passive radiators. 55 inches Hisense NU7700 audio structure diagram
The so-called passive radiator refers to the passive unit in the sound. The active unit in the cabinet passively vocalizes the air in the cabinet. One of the great advantages of audio systems equipped with passive radiators is that they can transfer the bass-producing burden of small-sized bass units to passive radiators of a larger size. Therefore, the bass sound area of ​​the Hisense NU7700 increases to 2.7 times that of the original. The volume of the sound is only 1/10 of the same effect. When the general audio bass is only 120Hz, the influence series can reach 60Hz super bass. The wide color gamut fine tuning began with the introduction of the first generation of ULED TVs in 2014. Hisense has created a series of achievements in ULED TVs from the key elements of backlight, panel, and picture quality chip. For example, this NU7700 supports dynamic backlight multi-zone control technology, self-developed Hi-View Pro image quality engine, and Acer 4D color display technology that incorporates smart light technology.
The NU7700 also supports HDR and is the full HDR. The HDR function is automatically recognized and enabled when HDR source is played, and the non-HDR film source screen is also optimized, but it is far less powerful than the HDR source.
Non-HDR film source

It can be seen that when playing HDR film sources, both the color and the details of the dark parts of the car body perform much better. As a World Cup custom TV, the performance of the dynamic picture is an important factor influencing the watching of the ball. The Hisense NU7700 is equipped with the Motion Flow function, which is consistent with the principle of the MEMC function.
