Xiaomi executives: mobile phone "chin" is hard to remove and cancel the headset hole is considered for antenna signal

"In promoting the technical element of comprehensive screen, the achievements of iPhone X / oppo find X are the most amazing. While increasing the proportion of screen, the black edge of" Chin "is almost removed. So why hasn't Xiaomi done it yet? Jai Mani, who is certified as the chief product manager of Xiaomi India by twitter, said that in addition to the bottom component connector mentioned by marques Brownlee in the video "smartphone" Chin ", another reason is to leave a" clearance area "for antenna signals. Headroom itself is a concept in the aviation field. It is used in the structural design of mobile phones to express that since the mobile phone antenna is an omni-directional antenna, enough open space is required around the antenna in the mobile phone to reduce shielding or interference as little as possible. Mani explained that Xiaomi uses a wide Chin (referring to mix 2 / 2S?) There is also a logical rationality, because the line of sight of people watching mobile phones is always natural from top to bottom, so it is wiser to place the clearance area at the bottom than at the top and side. While continuing to deepen, Mani also revealed that the bottom clearance area is also a reason for Xiaomi to cancel the 3.5mm headphone hole. In addition to the fact that the latter occupies the internal space, the headphone hole assembly will also interfere with the antenna and RF. He stressed that removing 3.5mm components has nothing to do with cost compression. After all, Xiaomi's usb-c to 3.5mm head is only $1.50 (domestic 9.9 yuan).
