Question 2: What are the cell phone parts? 20 points The main cell phone accessories are: LCD screen, wiring, touch screen, cell phone keys, camera, shell, battery, charger, mobile power, Bluetooth headset, in-line headset, data line and so on.
Question 3: What are the components that make up a cell phone? Cell phone structure
The structure of the phone generally consists of the following parts:
1, LCD LENS
Material: the material is generally PC or acrylic;
Connection: generally use the card hook + adhesive backing with the front cover connection.
Divided into two forms: a. Only in the upper part of the LCD; b. With the whole panel as one.
2. Upper cover (front cover)
Material: generally made of ABS + PC;
Connection: and the lower cover generally use the card hook + screw connection (screws generally φ2, it is recommended to use the locking screws in order to facilitate the maintenance, disassembly, the use of locking screws must pay attention to the material of the Boss, the aperture). Motorola's cell phones are more like all of them.
On the other hand, it is recommended to use locking screws for maintenance.
Lower cover (back cover)
Material: ABS + PC;
Connection: the use of snap hooks + screws to connect with the upper cover;
3, the key
Material: Rubber, pc + rubber, pure pc;
Connection: Rubber key is mainly dependent on the front cover to locate the pin growing out of the inner surface. Rubber key is mainly dependent on the front cover to locate the pin and the rib on the boss, Rubber key can not be accurately located, the reason is: Rubber is relatively soft, such as the key pad on the locating holes and locating the pin gap is too small (>
Question 4: What are the cell phone accessories include things? Not necessarily
Battery
Charger
Data line (sub-mobile phone)
CD-ROM wow sub-mobile phone)
Instruction manual
Warranty card
Headset
Generally these
Some have a gift to count
Question 5: What are the parts and components of the phone? This is too much, display, touch screen, battery, cpu, communication module (some of these modules will be integrated in the cpu), antenna, wifi bluetooth module, camera, frame, shell, nfc, ram, rom, a variety of sensors (distance, light, acceleration, and other sensors), microphone, microphone, speakers, audio processing chip, power management chip, this is too much!
Question 6: What are the parts of the phone is composed of According to the different models, the internal structure is also different, the necessary accessories are the handset, speaker, microphone, screen, keyboard motherboard and various chips, including capacitors, resistors, batteries. Previously, the degree of integration of cell phones is not very high, will be divided into a lot of single components welded to the motherboard, the current cell phone to many parts are concentrated on each chip, the circuitry on the motherboard can be divided into four panels: RF part \ logic part \ power supply part \ interface part. RF is responsible for sending and receiving signals to communicate with the outside world, including antennas and controllers frequency synthesis and power amplifiers, used for modulation and demodulation. Logic part has CPU and software memory and other components, is to deal with some routine operations, including control of the whole machine part of the work. The power supply part consists of the power supply IC and power supply tube, the battery is allocated to the various components to ensure normal operation. The interface part is to operate and communicate with us: such as display screen, SIM card, vibrator, ringer, keyboard, indicator and so on. There is the production of chips, the most popular cottage cell phone internal chip using MT chip (Taiwan MediaTek MTK manufacturing), the advantages are cheap, universal good, powerful. The disadvantage is that it is easy to contact poor, faulty, dead and so on. There are foreign such as Philips, Toshiba, SKYWORTH, Japan has a lot. Few domestic chip production, only some wiring, microphone, shell, battery, these things are produced domestically, there are many manufacturers, the general quality of the root price proportional to the price (15 dollars to buy the wiring than the 8 fast use of long time), the battery I know is the SCUD. The production process is basically manual plus assembly line, the shell can be assembled manually, the internal motherboard on the small parts is to use metal tin, the melting point is relatively low for welding.
Question 7: What are the brands of cell phone accessories? There are too many, the power supply has Philips ah, headphones and what, protective shells best class NINJACASE, so that every kind of ten or so, too much.
Question 8: iphone6 cell phone inside what parts Assembly of Apple 6 required parts: LCD assembly. Headset wiring, boot key, light sensitive wiring, earpiece, front and rear cameras, frame, vibration motor, wifi antenna, sim card tray, battery, home button and wiring, speakers, battery insulation film, frame eight small
Volume, mute and boot keys, microphone plug, a full set of screws, dust nets, interface wiring, key spacer: 2X4 pieces, wiring protection cover, brushed aluminum alloy rear cover, the Motherboard
Question 9: What are the main manufacturers of components for the domestic cell phone industry? 1, the main manufacturers of passive components market for cell phones
Murata, Kyocera, Sun Inducer, *** giant, Chilisin, Huaxin Technology, Daiyi Technology, Want to interpret, Japan's Rohm, AVX/Kyocera, TDK, Elna, EPCOS, Fenghua Hi-Tech, Kemet, Lelon, Matsuo Electronics, Nanyelectronics, Nichicon, Samsung Electro-Mechanics, Matsushita Electric, Vishay, Galaxy Technology, Xingqin Electronics
