At home, there was a 32-inch LCD TV bought 8 years ago. At that time, this brand-name domestic TV had a big face, a direct-read USB flash drive, and HDMI features that made me feel very avant-garde. However, with the advancement and development of science and technology, TVs have become larger and larger, more and more functions, and prices are getting cheaper and cheaper. Now, even the bedroom has 55-inch TVs on the walls. The old 32-inch TV was already planned to be sold to uncle.

With the continuous escalation of the pursuit of quality of life, we are also unwavering in pursuing a larger screen, higher picture quality, and HiFi sound quality. Consumer demand is rising. In this context, the need for home smart projectors came into being. Looking at the current mixed family projector market, there is no shortage of counterfeiting and hardware equipment. Some products are known as "supporting full HD," but the physical resolution is only 720p; some do not mark the brightness of the stream, only that the contrast is much higher, in fact, want to see the picture has to pull the curtains during the day, the house can not Turn on the lights, experience a big discount; some claim to support 100-inch large-screen projection, but because the focal length is too far, to go to 100 inches to go 3 meters away, in addition to the villa family is really difficult to have such a large space, Distance light attenuation is also a big problem...
Based on the above market pain points, Wah Tat and Tmall continue to complete the "magic box" product line to launch a "magic screen" home projector series, and the latest listing of Tmall magic screen S1 is its top flagship model, compared to At the same price, Tmall's magic screen S1 is very powerful, with a 0.8:1 ratio of light projectors, true 1080P resolution, wind noise of no more than 30 decibels, and an all-glass lens reaching 3,000 lumens, combined with Alibaba’s The gold-signed signboard has made this product unnoticed.
I also experienced this magical experience in the near future. How about the actual experience? How much difference between the actual parameters and the actual experience? Let's let the evaluation speak.
Both projection and high-end Bluetooth speakers I also experienced this magical experience in the near future. How about the actual experience? How much difference between the actual parameters and the actual experience? Let's let the evaluation speak.
Many home projectors have many interfaces, such as optical fiber, 5.1-channel output, Bluetooth, etc. It seems that they can connect very professional and high-end audio systems, but most families still use the default projector body speakers. To listen to the sound, and how to combine the sound system and the projector organically, Tmall Magic Screen S1 designed a brand-new way, can have a great sound effect at the time of booting, and can use it as a Bluetooth speaker after shutdown. This concept I think is a good innovation.
Anodized speaker network with metal JBL LOGO
In terms of appearance, the appearance of the Tmall S1 Founder happens to be the shape of a natural Bluetooth speaker. On both sides of the fuselage with large sound cavity ultrasonic seamless bonding technology, left and right each a JBL 10W symmetric speaker unit, which also has two symmetric bass passive diaphragm unit, can bring excellent high-medium low-frequency sound effects. And we know that JBL's golden signage represents the sound quality that is assured, and in actual use, it can also feel the shock it brings. It is low-frequency, and the mid-high range is full and clear, especially when watching movies. Because the location of the projector is closer to the viewer, the surround feel is stronger than if the speakers of the TV were to be sent from the screen location to the listener.
When you turn off the power button with the remote control, you can turn on the projector's "audio mode", you can use the remote control to control the speaker volume and switch, in the settings after the "listen to hear" mode is turned on, you can also in the remote control After the device is turned off, a radio music effect is achieved, and the online music player is randomly selected through the network. The practicality is given to 5 stars.
Light projector ratio 0.8:1, Small House Gospel I have evaluated many projectors, and generally have a situation in which the autofocus performance is not satisfactory. Some of them focus on the focus switch on the remote control. The focus is adjusted by the user's naked eye; or the focal length is too long. Projecting a large 100-inch screen on the wall requires the projector to move far behind. The maximum width of a small-sized living room like me is 3 meters. It is very difficult to increase the projected area.
This point I think Tmall magic screen S1 is very tough. First of all, its auto-focus system is very smart. It has a light distance sensor on the front. When the system is turned on for the first time, it can be seen that the system will perform a focus test. It takes about 3 to 5 seconds to focus automatically. , eliminating the need for manual focusing trouble. Secondly, it supports a 0.8:1 light projector projection ratio, so that a small living room can also enjoy the giant screen projection, as long as 1.8 meters can achieve 100-inch screen effect, the maximum can put a 300-inch screen, the equivalent of 36 50-inch screen.
I actually tested it. When the distance between the projector and the wall is about 1.4m, I use the tape measure to measure the length of the diagonal of the wall projection screen. It reaches 80 inches, and the picture is not deformed. This kind of strength is far away. Hyper-competitive products (nuts J6S and polar meters H1S projection ratio is 1.2:1).

A large, clear picture can also be projected in close proximity to the wall
Tmall's magic screen S1 has high brightness and contrast, and is inseparable from the all-glass lens it uses. The advantages of the all-glass lens design is that it can make the image display more stable and reliable, and can effectively solve the problem of the resin lens running anxiety. It can also prevent the blue LED light source from differentiating the CH polymer compound, and it can also effectively improve its stability and product protection. Scratch performance, but relatively speaking, the weight of the glass lens to increase a lot, but more delicate and intolerable collision, but fortunately home projectors are generally fixed in a position, man-made little impact.
In order to protect the lens, the body uses an electric protective baffle
Short focus effect and trapezoidal correction are too practical, the size of the household take-all It was also mentioned that short shots and large throw ratios are particularly suitable for small-sized homes, which allow larger screens to be shot at shorter distances, and that short focal lengths are also conducive to playing more light on walls and curtains to enhance viewing brightness. However, ordinary home users like me are more likely to decide to buy a projector for watching TV after the renovation is completed. It would be very troublesome to redesign the projector for the projector and the platform. At this time, the Tmall S1 screen 45o trapezoidal correction is too important!
For example, I placed the projector on the sofa armrest so that it would not block the projector's view, but it also facilitates the power cord routing. At this time, the 45° trapezoidal correction function is used to tilt the projector 45° to face the wall. Face, this time the screen default is oblique, such as the above picture, you can see the picture went to the bedroom door, do not worry, enter the settings interface trapezoidal correction options, directly pull the screen into a normal size, see below.
The projector is on the right
The projector is on the left
Even if the projector is in a quite position, after a simple adjustment, the screen can be kept horizontally and vertically. It can be seen that the font displays squareness and sharpness, and the picture is completely distorted. At this time, I turned off all the room lights and looked at the light leakage in the area beyond the focus position of the screen after trapezoidal correction. Because the all-glass lens is excellent in transmission, only light reflection leakage can be seen outside the center screen. That is to say, almost all of the light has converged on the position where the screen needs to be projected, and the effect is beyond my expectations.

Tmall's magic screen S1 changed the horizontal screen scrolling UI interactive interface in the traditional TV system, and used the interactive mode of scrolling up and down. The root directory is on the left side of the screen, and the right side is a block type menu system. The system supports the installation of third-party APPs. In addition to Youku and Mango, which have a cooperative relationship with Ali, they have built in-depth and can also install clients such as Kiwi, TV 2.0, and Tencent videos. It is believed that friends who are often chasing plays can rest assured at the moment.
In addition, the system operation is also smooth and smooth. I have installed several APP clients. No compatibility problems have been found. The system response speed is also very fast. I believe if you have used various smart boxes, you will get started with Tmall Magic Screen S1. It will not be handy, and it will be easy and stress-free.
Solid workmanship, design avant-garde In addition, the system operation is also smooth and smooth. I have installed several APP clients. No compatibility problems have been found. The system response speed is also very fast. I believe if you have used various smart boxes, you will get started with Tmall Magic Screen S1. It will not be handy, and it will be easy and stress-free.
Finally, let's take a look at the characteristics of the work and detail design of the body of the Tmall Magic Screen S1.
The overall body view, Tmall magic screen S1 appearance is still relatively traditional, Founder's shape is also very easy to place, silver black body is also very wild, do not feel very abrupt in the indoor room, and compared to the white machine The body is also more resistant to dirt. The fuselage adopts aluminum alloy + ABS material, without too much decoration, relatively simple.
The remote controller communicates with the host through bluetooth. The voice cloud voice recognition button is set on the remote controller. Based on the user experience of the Tmallbox remote control, it is optimized. It is OK to press directly on the remote controller. Search and operation are very convenient.
There are four foot pads at the bottom of the fuselage to raise the airframe to facilitate the air flow at the bottom
The side red JBL logo is very eye-catching
There is a large area of ​​heat dissipation at the back and bottom of the fuselage, because the built-in dual fans, in the case of ensuring the heat dissipation inside the body, the dual fan can reduce the speed to achieve low decibel caused, which is very important for noise reduction. And the built-in German Osram LED light source also achieves a very high luminous efficiency, which is also effective in reducing heat generation.
In addition, if the bottom of the fuselage design a screw hole is better, you can use a tripod or speaker platform to achieve a fixed, if only rely on the bottom of the fuselage four rubber mats to fix, then there is still a risk of falling.
In conclusion, Tmall's magic screen S1 really gives me the feeling that “a good steel is used on the bladeâ€. It doesn’t “get brains†in the fancy and unrealistic features of appearance, but it’s really relevant. The intrinsic effect of the experience under the full effort, 0.8:1 projection ratio and 3000 lumens brightness and greater than 120% of the color gamut performance, make this smart projector far behind the competing products left behind, and when the family is switched on After the theater is turned off, the design of the high-quality bluetooth speaker is also very grounded. It feels cool to use it. If you live in a small apartment with a wide range of high-quality products, you want to experience the shock effect of the large screen. This Tmall magic screen S1 is definitely your best choice.
