Cell phone back cover design on the market today are divided into two kinds, is a mirror-glass design, the other is a three-stage design. The former looks more beautiful, do better integration of the fuselage, but the durability and easy fingerprint. Three-section design in use and metal texture is superior to the more durable. Has been a mobile technology leader Apple iPhone 4/4S is the mirrored glass back cover design, the iPhone 5 and after products are built using metal three-section design.
In order to pursue a better texture, released after iPhone6 is 5/5S of the upper and lower ends of the plastic instead of metal. But due to the metal body signals for mobile phones have a lot of obstacles, iPhone6 antenna with wider ways to ensure signal quality, and here the antenna is used to ridicule the "vaginal discharge".
Why Mobile must exist "vaginal discharge"? For signals and what kind of impact, small series below to the first use of such "vaginal discharge" iPhone6 design as an example, explain "vaginal discharge" of great importance. IPhone6 open back cover, as you can see, seemingly one of the metal back cover is actually a plastic filler, apparently is divided into three sections, and both ends of the antenna, while the middle is responsible for conduction. IPhone6 part antenna involves Cellular antennas, WLAN and Bluetooth. Such as GPS, NFC, and the following are some of the major Cellular antennas.
From this we can see iPhone6 as Netcom's mobile, increasing this kind of mobile phone "vaginal discharge" is Apple in order to signal to select more, but also to ensure the signal quality stability of last-ditch move. This last ditch design is also all-metal rear cover good signal solution of 2015, so domestic mobile phone manufacturers to exclusively use such programmes.
Now the popular "vaginal discharge" process is CNC plastic injection molding. CNC plastic injection which is controlled by the so-called automatic machines, metal injection molding process of partition.
CNC plastic injection in different phones have different solutions, such as mainstream in 2015 in the three-stage design. In 2016, many manufacturers have a new way of thinking, in leucorrhea location better than Apple and even innovative. First approach cell phone antenna hidden in the frame's position, very good design, not only hides the "vaginal discharge", and signal extension can also strengthen the signals receiving and sending.
Another way is that the back cover metal has been extended to cover the upper and lower parts, CNC hole in the bottom section, opened a large location for injection molding process. Not only cleverly hide the antenna, you can also let cell phone back cover metal and plastic part of the transition, keeping the fuselage design of one, while more delicate beauty.
In addition, Huawei's mate s of the t-shaped antenna, which cleverly took advantage of the shape of the antenna, look more symmetrical and beautiful.
One sentence summary: Disney Galaxy Note 4 case
Due to currently technology of limit, currently also no found perfect solution metal Hou cover shielding of way, so "leucorrhea" also President time exists, since "leucorrhea" cannot elimination, that we should for species thinking to treats it, not blindly of canceled it, can will leucorrhea into fuselage design among, let leucorrhea became phone design of part, so, it not only enhanced signal received capacity, more can upgrade phone yan value, so why not does?
