When TV boxes are bought, they have low profits and low prices. Businesses can earn money by forced insertion of advertisements, various types of startup advertisements, standby advertisements, and video advertisements. Very annoying, the sense of experience for the family is also very poor. Second, the system page is complicated, and upgrade and maintenance are insecure The low price TV box is not optimized for the general system page, and it is difficult to use. For the average family member, the elders, the elderly, and the children and the wives are struggling to operate. Firmware upgrades and maintenance are also very slow. Such low-cost vendors basically have no relevant technical maintenance personnel to follow up. Follow-up product failures and maintenance repairs are all major problems. Third, can not run smoothly for a long time Many people are reluctant to buy two or three hundred for their mobile phones. The reason is that they use more cards. The TV box is also an Android system. The low-priced box is very poorly used. It can be used just after it is started. After several months or even a month, it will start all sorts of stalling, flashback, or crashes. So buying boxes really doesn't buy cheap boxes. Tai Jie, Huawei box comprehensive comparative evaluation 1 video playback performance The Taijie box also comes with the Thai-Television video. When the Thai-German video is played on the Thai-Thai box, the page will automatically skip advertisements. After the video is opened, the advertisement can be skipped and the film source can be loaded for playback within three seconds. My own home is a telecommunications 20M, the general Blu-ray super clear source can easily get. 2 Home users get up and down, easy to use After the Tate box is powered on, there are three main sections, "Let's Have a Look," "TaiJie Video," and "The Game Center." If you watch the video, you can open it directly. Not too redundant recommendations and advertisements are presented in a neat and simple manner. Unlike some of the pre-installed software with a lot of boxes, the system is complicated, and there are a bunch of advertisements that make it very complicated to operate. Taijie is a professional old driver and knows well that the needs of users are watching TV and video. Therefore, focusing on the video playback experience, the system developed is simple and easy to operate! The layout of Huawei's boxes is also relatively neat and the columns are also very rich. Movies, TV shows, variety shows, anime, etc. However, you must select the main column from top to bottom to select the section. For older people and children who do not understand the box, they are relatively unfamiliar, but they are still familiar with several times. 3 advertising length The length of the advertisement of the Tate box can be said to be zero. The boot is free of advertisements. Look at the video that Tyger brings. There is almost no advertising. The ad has been blocked every time. Some popular variety shows have a few seconds of advertising, which may be the reason why the film originated. But you can skip it quickly by pressing the fast forward button. Compared to other boxes, there must be 30-120 seconds of advertising before watching the video. The experience is so much better! It can be said that TV boxes on the market are basically advertising, Huawei glory is no exception. However, Huawei is mainly watching videos with titles. As for many shopping advertisements for which low-priced boxes are mandatory, pop-up ads are still rare in Huawei's boxes.
Yuhai piezo materials include : hard piezo material, soft piezo
material and lead free piezo material
Soft piezo
material exhibits: larger piezoelectric constants, higher permittivity, larger
dielectric constants, higher dielectric losses, larger electromechanical
coupling factors, low mechanical quality factors, a lower coercive field, poor
linearity, and is easier to depolarize. The ideal application of soft piezo materials is sensing needs. Yuhai soft
pizeo materials are PZT-5, PZT-5H, PSnN-5 and PLiS-51.
Hard piezo
material exhibits: smaller piezoelectric constants, lower permittivity, smaller
dielectric constants, lower dielectric losses, smaller electromechanical
coupling factors, high mechanical quality factors, a higher coercive field,
better linearity, and is harder to depolarize. The ideal application of hard piezo materials is high power transducer needs. Yuhai hard pizeo materials are PZT-4, PZT-8, PCrN-4 and PBaS-4.
Yuhai company developped lead free piezo material BaTiO3 and apply for the Chinese Patent in 2011, to meet the needs of environmental protection in today's society.

Tai Jie, Huawei box comprehensive comparison evaluation cheap box shaking trap large exposure
More and more low-cost, low-standard, low-quality box manufacturers have entered the TV box market. Many consumers have fallen into the low-cost traps of merchants for the sake of arrogance. In order to prevent more consumers from being invaded by businesses, Xiao Bian summed up the disadvantages of some of the low-priced boxes. We can refer to them. The system of the Huawei box is also running well. Basically, it can run the operating system smoothly. It is also possible to play video. Although the 4K decoding capability is relatively poor, it can meet the requirements of many users in terms of definition and fluency. Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
First, advertising is particularly large
In addition, exclusive “soft decoding†and “hard decoding†video decoding technology of TRT video can switch the decoder on its own, allowing users to watch video more smoothly, which is also a powerful video decoding capability!
