[PConline evaluation] When the cool open glorious A55 television was released in October, people around it were very curious about it. Of course, the curiosity basically revolved around its no-interface back and "all wireless" control methods. Many friends Said that it is not understood: it does not have the interface on the back not only all the interfaces are gone, even the speakers seen on other TVs have not been seen, so this design will have a good sound quality? Although all of the control methods are wireless, we have also seen that in the evaluation, the control is very rapid and smooth. Will the adoption of this wireless transmission form bring great radiation to the user's home? In response to these two issues, we will begin to answer one by one.

Because there is a "CHAI" word from the title, our method for answering the first question is mainly answered by the method of tearing down the whole TV set.

What is the good sound quality of the Cool A55?

When we answer this question, we can first look at a video. We recommend opening the voice and listening to the following video.

Sound quality is good This is a relatively subjective thing, so the author here is not conclusive, but from the loudness, cool open glory A55 is still very good, the test environment is a large room about 30 square meters, songs The prelude sounded, still very powerful. Now the question is: In the end, how many speakers does the Cool A55 have? How can this expressiveness be? No matter how late, the following directly into our disassemble link.

The method of removing the shell is relatively simple. We only need to screw down all the screws on the back.

Soon we dismantled the "metal-like" appearance of the plastic back shell. We can roughly look at the back of the back shell.

Here is the turn of the chip and the panel that everyone is very concerned about, because according to the characteristics of “All is wireless” of Cool Open A55, many components of Cool Open Honor are specially designed.

The following is the turn of the speaker part that we are more concerned about. We can see two black boxes on the bottom edge of the motherboard. These two are the audio modules of the Cool Open A55 glory. I remember those who were cool to open at the experience meeting expressed their coolness and glory. The A55 uses the largest and best sound module in the sound chamber, with volume allowed.

As shown by the arrows, each audio module of the CoolOpen Glory A55 has three speakers

Summary: Through the dismantling of television, Cool open glory A55's workmanship and the use of materials at a glance, in order to achieve the desired design goals, cool open glory A55 in the selection of parts is really under the capital.

The radiation problem of the "all wireless" control method

When this innovative, industry-leading, wireless operating method was introduced in the cool open A55 glory, many of my friends found it very fresh, very fun, very good, but there are a lot of friends who have married and have a child to ask: Will this kind of wireless manipulation bring new home electromagnetic radiation problems? Hey, this question is still very fresh and interesting. I have neglected this aspect when evaluating the product. Let's take this opportunity to make a test.

To test the radiation, you must ask for the necessary accessories for Skyworth A55: four HDMI wireless signal transmitters. Through a set of transmitting and receiving devices, we can easily pass the signals of various audio and video devices at home. The HDMI input is input and transmitted to the TV for playback.

Test method: Input the video signal through the HD box, from the 1080P video signal to the 4K video signal, and test the radiation value at the normal use viewing distance. (The data of this radiation test is tested in a real environment, and other radiation sources are not shielded. All values ​​represent more than just radiation data from the product.)

The electromagnetic radiation value measured by the instrument at the normal viewing distance (55 inches and 3 meters) is 16.2V/M

Test data at normal viewing position when inputting and transmitting 1080P signals

Test data at normal viewing position when inputting and transmitting 4K signals

I believe that people who read the above data will have doubts: When it is not time to transmit 4K signals, what is the maximum amount of data that needs to be transmitted? Why is the value displayed smaller than 1080p? In fact, this problem is not difficult to answer: Because the impact of the TV transmitter on the instrument in the normal viewing position is minimal and almost negligible, the value on the instrument changes due to changes in other variables in the surrounding environment. This also reflects from the side that this set of wireless transmission and transmission system is very safe and will not bring about great electromagnetic radiation interference to the user's home.

Conclusion: In the era of highly homogenized products on the market, any company that wants to introduce new products must find ways to find bright spots and find gimmicks. However, there are many companies’ bright spots. The gimmicks cannot withstand evaluation. Verification, and in this regard, cool open glory A55 is undoubtedly done is still good: all the hardware choices are to achieve the function of the service, the real one-by-one use of the consumer to implement, what money to spend What kind of products can be really obtained, such honesty and trustworthiness are indeed worth vendors, market development, promotion.
