A hundred inch TV costs tens of thousands, but its 300-inch giant screen costs less than one tenth.
And today, it is from the well-known domestic projector manufacturers cool music as the current flagship product, there is "day screen theater," said the cool music as the S3.
The appearance of the S3 is much more pleasing than that of a traditional projector's well-proportioned exterior design, although it appears to be a boxy box, with a black painted roof and aluminum-titanium alloy hollow metal frame, business The atmosphere is still strong. However, the rounded corners and the compact body design (225 x 225 x 53mm) have a weight of only 1.5kg, making the S3 a good fit for all styles of home scenes.
Hollow metal frame is not only excellent in texture, but also a lot of points for S3. This design is not only for beauty, but also a more practical role is to greatly enhance the cooling effect of S3, and enhance the stability of the device at work.
It can be said that S3 is a product that closely follows the pace of science and technology. You will find that S3 does not have a physical button on the entire body. Instead, it is currently the mainstream somatosensory operation on LED smart projection. Touch the COOLUX logo on the top of the body to complete the boot operation. In addition, the LOGO will send a light blue glossy prompt to boot. The LOGO below is obviously integrated with a sensor to perform corresponding operations by touching the user and waving his hand.
The S3 interface basically covers the main interface that can be said to have covered the current input and output: from the earphone jack to the AV hole, LAN, HDMI*2, USB*2, and DC interface. In particular, the S3 has an ANT interface. This shows that the S3 has a built-in terrestrial digital TV DTM. By using an external antenna, you can watch high-definition TVs without a network. This also makes the S3 more practical.
In terms of random accessories, the S3's collocation is very simple. In addition to the conventional power adapter, the core accessories are only remote controllers. Remote control design is very simple and intuitive, easy to use, from top to bottom buttons in order for the switch, focus, direction and selection, menu, HOME, return, 3D and volume, manual focus keys, in addition to 3D keys, indicating that S3 is Supports 3D playback. Remote control is matte material, comfortable grip.
In fact, the highlight of the S3 is almost always on the front of the fuselage. This time, in order to provide better protection for the lens, S3 added a sliding lens protection cover to block dust. At the same time, with the slide closed, open the slide to power on.
This lens, which can project brightness up to 1000 ANSI lumens, is undoubtedly the biggest highlight of S3. This data is also certified by the National Center for Digital Audio, Video and Multimedia Product Quality Supervision and Inspection.
S3's lens has a camera-like little thing next to it. It is actually a design for assisting auto focus. That means that when the S3 is turned on, the projection screen will be autofocused, trapezoidal correction and other adjustment actions, but if the user feels Without achieving optimal results, manual focus adjustments can also be made via the remote control.
The HiVi nameplate in the lower right corner of the front of the fuselage should also make many HiFi fans excited. Indeed, the combination of the internationally renowned Swans speakers and S3 is believed to give users a more perfect audio-visual experience.
Cool music as the details of the S3 design is still in place, such as the bottom of the fuselage four small feet each can be adjusted to facilitate the user to level the fine-tuning. In addition S3 uses the national standard screw hole, located in the center of the fuselage bottom, common with the ordinary SLR tripod.
The S3 uses a 64-bit smart chip, the Mali-T720 3D image processor. This configuration of the CPU and GPU is also the current mainstream smart TV configuration. On the operating system, S3 is equipped with a cool OS system that is deeply customized by Android. The overall system design style is biased towards simplicity. The main interface is divided into four major applications (video, music, office, and application). Compared with Cool LeTV's previous product system UI, the interface is obviously beautified, the functions are eye-catching, operation fluency, program running rate, and 4K video decoding capability are greatly improved.
With the support of Swans Audio, S3 can be said to have improved the audio experience. Therefore, S3's support for music playback naturally rises. In the supply of high-quality music resources, Cool Music has access to third-party resources and has performed well on listening experience.
WiFi, Bluetooth, images (keystone correction, autofocus, installation mode, etc.), sound (speaker mode settings) and other core functions such as LED smart projection are readily available. The S3 can support positive and negative projections, rear projections, front projections, and rear projections. "Wall color correction" is considered a small design of S3, the official said that S3 comes with a wall color correction system, can adjust the color of the screen according to the wall color, so that the projection shows a higher reduction of the screen. Even without the screen, the screen performance of the S3 is still stronger than most projectors.
The above photos are all S3's real shot effects. The camera shooting effect is slightly biased and the actual effect is even better. Bright and dark contrast of the screen is clear and strong. At the same time, details such as the sky clouds, mountains and green water, and the outline of the flowers are also very delicate. The projected image is of clear color and high saturation.
In general, although the appearance of Cool Music as S3 is not great innovation, but it wins in the wild! Whether it is a business presentation or home use is very suitable. Thousands of lumens of brightness also minimize the impact of light on the projected picture. A small micro-projection can give the user a 300-inch movie theater experience. However, if you use it at home, it is recommended not to make the projected picture larger than 150 inches. Less than 4K price, but can have a hundred inch big screen high-definition theater, is that those who have the pursuit of large screen is really a good choice.

Usually,10 & 20 layers PCB are HDI board,but some are not .Some with big trace width and space,holes are over 0.3mm too. We have much experience in doing 10 layer PCB & 20 layer PCB.
A ten-layer board should be used when six routing layers are required. Ten-layer boards, therefore, usually have six signal layers and four planes. Having more than six signal layers on a ten-layer board is not recommended. Ten-layers is also the largest number of layers that can usually be conveniently fabricated in a 0.062" thick board. Occasionally you will see a twelve-layer board fabricated as a 0.062" thick board, but the number of fabricators capable of producing it are limited..
High layer count boards (ten +) require thin dielectrics (typically 0.006" or less on a 0.062" thick board) and therefore they automatically have tight coupling between layers. When properly stacked and routed they can meet all of our objectives and will have excellent EMC performance and signal integrity.
A very common and nearly ideal stack-up for a ten-layer board is shown in Figure 12. The reason that this stack-up has such good performance is the tight coupling of the signal and return planes, the shielding of the high-speed signal layers, the existence of multiple ground planes, as well as a tightly coupled power/ground plane pair in the center of the board. High-speed signals normally would be routed on the signal layers buried between planes (layers 3-4 and 7-8 in this case).
