Xiaomi 6

The Xiaomi 6 was disassemble in detail to help you have a comprehensive understanding of the structure of the Xiaomi 6 . There are mainly six secrets that attract users.

1, SIM card tray airtight rubber plug, anti-splash from the start

The reason why Xiaomi 6 can support splash-proof is because there are more than ten airtight designs in the whole body. The most obvious one is the SIM card drag. Pull out the card tray and see a circle of soft glue around. When the card tray is inserted, the soft rubber and the SIM card slot of the housing are in an interference fit, and the soft rubber is squeezed and filled in the gap between the SIM card tray and the card slot to block the water outside the body cavity.

2、Super large area graphite heat sink, it is a conscience

By heating the open backing plate, it can be found that there is a large graphite heat-dissipating film inside the backing plate, and this almost covers the entire interior of the panel. ZEALER's dismantling personnel also exclaimed: "The area of the mobile phone has been removed so far. biggest". The heat-dissipating graphite film is a very thin GTS, a comprehensive thermal conductive material suitable for rapid heat conduction from a point heat source to a surface heat source, and has high thermal conductivity, so it is also a necessary heat-dissipating component in most mobile phones, but like The full-area heat-dissipating film of the meter 6 is indeed rare.

3, the earpiece integrated speaker function, stereo effect get

As can be seen from the disassembly, the earpiece of Xiaomi 6 is very large, which is because the output of the earpiece volume is greatly increased. In this way, the earpiece can be used as a second speaker to assist the original bottom speaker to form a dual stereo effect.

4, the dual lens module is highly integrated, making the smallest cursor dual camera

iPhone 7 Plus lens split diagram

The Xiaomi 6 dual lens is assembled in one piece, unlike the split dual module design used in the iPhone 7 Plus. As can be seen from the comparison chart, although the iPhone 7 Plus also encapsulates the dual lens in a protective cover (as shown in Figure 1), the actual lens is a separate module, and the two modules are separated (Figure 2). There is an independent drive motor in a single module, and the modules are only glued together and then packaged into a metal protective cover. The dual lens of Xiaomi 6 is fully integrated in the same module, and the integrated motor design can effectively reduce the space size of the lens assembly. The highly integrated design allows the optical zoom dual lens to be carried in the 5.15-inch body of the Xiaomi 6.

5, linear motor, vibration is crisp and refreshing

The key component of the millet 6 body vibration is the linear motor in the green box in the picture above, which provides all the power of the phone vibration.

At present, mobile phone vibration units on the market are basically divided into two categories: a rotor motor and a linear motor. The rotor motor has an off-center rotor that applies a positive voltage motor rotation and applies a negative voltage motor brake. As an early motor solution, the advantage is that the technology is mature and low cost, but it will have the effect of "sloshing" the fuselage during vibration.

The linear motor is the mainstream solution adopted by the current high-end machine. Because of the combination of the magnet and the spring, the vibration is refreshed and crisp. In short, it is simply shocking and stopping, so as to avoid the soft continuation of the previous rotor motor after the vibration is stopped.

6, copper alloy heat sink, cooling master hidden tricks

The metal plate that was exposed when it was finally removed is of great use. It seems that its appearance is not good but has far-reaching significance to the structure of the mobile phone. It not only enhances the strength of the fuselage, but more importantly serves as a key channel for internal heat dissipation. It is important to know that for high-performance mobile phones, heat becomes the main roadblock for performance, and timely and effective heat dissipation is required for major heat sources (such as processing units). The copper-iron alloy heat sink of Xiaomi 6 will effectively radiate the energy in the concentrated area of heat, and exchange heat with the environment through the stainless steel frame to cool down.

The reason why copper alloy is chosen is because it has extremely high thermal conductivity. Compared with stainless steel, the thermal conductivity of 16W/m·K (thermal conductivity is a physical quantity indicating the heat transfer capacity of a material), copper alloy can reach 350W/m·K, can quickly heat the entire body quickly, avoiding the performance degradation caused by the local heating of the processing unit.
