The image frame processed by the graphics processor 1041 can be stored in the memory 109 (or other storage medium) or sent via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) via the microphone 1042 in a telephone call mode, a recording mode, a voice recognition mode, and other operating modes, and can process such sound into audio data. The processed audio (voice) data can be converted into a format output that can be sent to a mobile communication base station via the radio frequency unit 101 in the case of a telephone call mode. The microphone 1042 can implement various types of noise elimination (or suppression) algorithms to eliminate (or suppress) noise or interference generated in the process of receiving and sending audio signals.

[0041] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and / or the backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured on the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect the user's touch operation on or near it (such as the user's operation on the touch panel 1071 or near the touch panel 1071 using any suitable object or accessory such as a finger, stylus, etc.), and drive the corresponding connection device according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the touch point coordinates, and then sends it to the processor 110, and can receive and execute the command sent by the processor 110. In addition, the touch panel 1071 can be implemented in various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072.

[0044] Optionally, the touch panel 1071 may cover the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. Then, the processor 110 provides corresponding visual output on the display panel 1061 according to the type of touch event. Figure 1 In the figure, the touch panel 1071 and the display panel 1061 are used as two independent components to implement the input and output functions of the mobile terminal. However, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to implement the input and output functions of the mobile terminal, which is not limited here.

[0046] The memory 109 can be used to store software programs and various data. The memory 109 can mainly include a program storage area and a data storage area. Optionally, the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the mobile phone (such as audio data, a phone book, etc.), etc. In addition, the memory 109 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0047] The processor 110 is the control center of the mobile terminal. It uses various interfaces and lines to connect various parts of the entire mobile terminal. It executes various functions of the mobile terminal and processes data by running or executing software programs and / or modules stored in the memory 109, and calling data stored in the memory 109, so as to monitor the mobile terminal as a whole. The processor 110 may include one or more processing units; preferably, the processor 110 may integrate an application processor and a modem processor. Optionally, the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 110.

[0048] The mobile terminal 100 may also include a power supply 111 (such as a battery) for supplying power to various components. Preferably, the power supply 111 may be logically connected to the processor 110 via a power management system, thereby implementing functions such as charging, discharging, and power consumption management through the power management system.

[0049] although Figure 1 Not shown, the mobile terminal 100 may further include a Bluetooth module, etc., which will not be described in detail here.

[0050] First embodiment

[0051] Based on the above mobile terminal hardware structure, various embodiments of the present application are proposed. In the design and manufacturing process of smart terminals, decorative parts can not only beautify the appearance, but also play a certain protective role for various components of smart terminals. NFC (Near Field Communication) antenna is an important communication module in smart terminals. When the decorative parts occupy a large proportion of the width of the smart terminal, it will cause a certain degree of obstruction to the NFC antenna, thereby affecting the performance of the NFC antenna.

[0052] In some solutions, smart terminals are generally equipped with camera modules, and in order to improve their camera performance, large-sized lens modules are usually selected, or the camera modules include more cameras. This leads to a gradual increase in the area occupied by the camera module in the design of smart terminals, and in order to maintain the overall beauty and functionality of the smart terminal, the corresponding position of the camera module also needs to be equipped with corresponding decorative parts, which leads to a large proportion of the width of the smart terminal occupied by the decorative parts.

[0053] Traditionally, when the decorative parts occupy a small proportion of the width of the smart terminal, the NFC antenna can reduce its performance degradation by bypassing the decorative parts and maintain good NFC signal transmission. However, with the popularity of large-size camera modules, the width of the corresponding decorative parts occupies a large proportion of the width of the smart terminal. The single-ended NFC antenna cannot bypass the decorative parts. The decorative parts will cover the NFC antenna and absorb the magnetic field generated by the NFC antenna, reducing the performance of the NFC antenna. At the same time, as the size of the camera module increases, the thickness of the corresponding decorative parts remains high, forming a natural height barrier between the NFC antenna and the smart terminal, which causes the smart terminal to be closer to the external device 700 to interact with it normally, which also reduces the performance of the NFC antenna.

[0054] See also Figure 1 , which is a schematic diagram of the structure of an NFC antenna assembly according to an embodiment of the present application. The NFC antenna assembly includes an NFC antenna and a decorative part. The NFC antenna has a first antenna portion 410 and a second antenna portion 420. The decorative part includes a decorative part body 310. The first antenna portion 410 and the second antenna portion 420 are arranged on both sides of the decorative part body 310.

[0055] In this embodiment, the NFC antenna is used to realize near field communication functions, such as mobile payment, access control, data exchange and other functions. It can be a single-end NFC antenna, a double-end NFC antenna, a combination of a single-end NFC antenna and a double-end NFC antenna, or other types of NFC antennas. The NFC antenna can be set to various shapes such as L-shape and C-shape. In this embodiment, the NFC antenna includes a first antenna part 410 and a second antenna part 420, which are respectively located on both sides of the decorative part body 310 to realize the transceiver function of the NFC signal. Optionally, the type and shape of the NFC antenna can be selected according to the overall design and performance requirements of the smart terminal, which is not limited here.

[0056] In this embodiment, the decorative parts can be arranged corresponding to the various components of the smart terminal to decorate the corresponding components and protect them at the same time. Optionally, the decorative parts may include any structural parts in the mobile terminal such as camera module structural parts, middle frame structural parts, speaker structural parts, etc. The embodiment of the present application is illustrated by taking the decorative parts corresponding to the camera module structural parts of the mobile terminal as an example. Optionally, the decorative part body 310 can be a conductive material such as metal, metalloid, alloy, or an insulating material such as plastic, ceramic, etc., or a combination of conductive material and insulating material. The specific material can be selected according to the overall design and performance requirements of the smart terminal, and is not limited here.

[0057] In this embodiment, reference Figure 2 , the first antenna portion 410 is the solid line portion, and the second antenna portion 420 is the dotted line portion. The first antenna portion 410 and the second antenna portion 420 are arranged on both sides of the decorative part body 310. Through the first antenna portion 410 or the second antenna portion 420, it is possible to directly interact with the external device 700 to realize the near field communication function. Optionally, the external device 700 can be an NFC card, an NFC card reader or other device that supports the NFC function. In the embodiments of the present application, the interaction between the first antenna portion 410 and the external device 700 to realize the near field communication function is taken as an example for explanation.

[0058] In this embodiment, reference Figure 3 , which is a schematic diagram of the cross-sectional structure of a decorative piece of an embodiment of the present application. When the width of the decorative piece occupies a large proportion of the width of the smart terminal, the NFC antenna cannot bypass the decorative piece. The first antenna part 410 is placed on one side of the decorative piece, and the first antenna part 410 interacts with the external device 700 to realize the near field communication function, which can reduce the shielding of the first antenna part 410 by the decorative piece, thereby reducing the NFC magnetic field absorbed by the NFC antenna due to the covering of the decorative piece by the NFC antenna. At the same time, the first antenna part 410 can directly interact with the external device 700, and there is no decorative piece blocking between the two, which increases the interaction distance of the NFC of the smart terminal, effectively solves the problem of the short interaction distance between the NFC antenna and the external device 700 caused by the thickness of the decorative piece, and thus improves the performance of the NFC antenna. It can be understood that when the length of the first antenna part 410 is longer and the length of the second antenna part 420 is shorter, its ability to receive and transmit external NFC signals will be correspondingly enhanced, which can correspondingly improve the performance of the NFC antenna. Optionally, when the second antenna portion 420 is a solid line portion, the first antenna portion 410 is a dotted line portion, and the second line portion is used to interact with the external device 700 to implement the near field communication function, the same effect can be achieved.

[0059] In this embodiment, the NFC antenna assembly includes an NFC antenna and a decorative part, and the first antenna part 410 and the second antenna part 420 of the NFC antenna are arranged on both sides of the decorative part body 310, so that the first antenna part 410 or the second antenna part on one side of the decorative part body 310 can directly interact with the external device 700 to realize the near field communication function, thereby reducing the NFC magnetic field absorbed by the NFC antenna due to the covering of the decorative part. At the same time, since the first antenna part 410 or the second antenna part 420 directly interacts with the external device 700, there is no decorative part blocking the two, which effectively solves the problem of the short interaction distance between the NFC antenna and the external device 700 caused by the thickness of the decorative part. The present application is conducive to improving the performance of the NFC antenna, increasing the interaction distance of the NFC of the smart terminal, and improving the user experience of the NFC function.

[0060] Second embodiment

[0061] Based on any of the schemes in the above embodiments, a through hole 320 may be provided on the decorative part body 310, and the first antenna part 410 and the second antenna part 420 are electrically connected through the through hole 320. In this embodiment, the through hole 320 may be one, two, three or other numbers. When there is one through hole 320, it may be arranged at the center of the decorative part body 310 or at the edge of the decorative part body 310. When there are two, three or more through holes 320, they may be arranged according to preset layout rules, such as equidistant arrangement, symmetrical arrangement, etc. In this embodiment, the specific number and specific position of the through holes 320 may be set according to factors such as the size of the camera module, the position of the camera module, and the layout of the NFC antenna, and are not limited here.

[0062] Optionally, the NFC antenna can directly penetrate the through hole 320, thereby realizing the electrical connection between the first antenna part 410 and the second antenna part 420. This connection mode not only ensures the stable transmission of the signal, but also simplifies the structure of the antenna and reduces the manufacturing cost. Optionally, when the decorative part is a conductive decorative part, its material is metal or metalloid and has good conductivity. In order to reduce the influence of the decorative part on the performance of the NFC antenna, in this embodiment, the decorative part is insulated from the NFC antenna. Optionally, an insulating layer can be provided on the inner side of the decorative part body 310 (i.e., the side in contact with the NFC antenna) and the inner side of the through hole 320, or the decorative part body 310 and the through hole 320 are coated with an insulating material to achieve insulation between the decorative part and the NFC antenna. In this way, even when the decorative part is made of conductive material, its influence on the performance of the NFC antenna can be effectively reduced to ensure the stable transmission of the NFC signal.

[0063] Optionally, the through hole 320 is a conductive through hole, and the first antenna part 410 and the second antenna part 420 are electrically connected to the conductive through hole, respectively. In this embodiment, the conductive through hole can be implemented in a variety of ways. For example, after a through hole is opened on the decorative part body 310, a conductive material (such as metal powder, conductive paint, etc.) can be filled in the through hole to form a conductive through hole. In addition, it can also be achieved by directly processing a through hole with conductive properties on the decorative part body 310. It should be noted that when the decorative part is made of conductive material, the connection part between the conductive through hole and the decorative part body also needs to be insulated to reduce the impact on the performance of the NFC antenna. The insulation treatment of the connection part between the conductive through hole and the decorative part body can be achieved by providing an insulating layer or using an insulating material in the connection part.

[0064] Optionally, the decorative part is a conductive decorative part, and the first antenna part 410 and the second antenna part 420 are electrically connected through the conductive decorative part. In this embodiment, the first antenna part 410 and the second antenna part 420 can be electrically connected through a conductive path formed inside the conductive decorative part, that is, this connection method utilizes the conductivity of the conductive decorative part itself, and realizes the reuse of the decorative part as a decorative or protective component of the smart terminal and the electrical connection function of the first connection part 410 and the second connection part 420, thereby eliminating the need for additional connecting wires or structures, simplifying the design of the NFC antenna assembly, and reducing manufacturing costs.

[0065] Optionally, the number of through holes 320 is at least two, and the NFC antenna passes through at least two through holes 320, so that the first antenna part 410 and the second antenna part 420 are arranged on both sides of the decorative part body 310. In this embodiment, the NFC antenna can pass through at least two through holes 320 in sequence according to a preset order, for example, first pass through the first through hole 320 so that the first antenna part 410 is located on one side of the decorative part, and then pass through the second through hole 320 so that the second antenna part 420 is located on the other side of the decorative part, and then cycle in this way. Optionally, the first antenna part 410 can also be located on one side of the decorative part through the first through hole 320, and then pass through the second through hole 320 after a preset length or a preset number of through holes 320 from the first through hole 320, so that the second antenna part 420 is located on the other side of the decorative part, and cycle in this way. It is understandable that when the NFC antenna passes through multiple through holes 320 in sequence, multiple first antenna parts 410 or second antenna parts 420 can be formed on both sides of the decorative part. At this time, multiple first antenna parts 410 or second antenna parts 420 interact with the external device 700 to realize the near field communication function, and the above effect can be achieved. In this way, it is ensured that the NFC antenna can stably penetrate the decorative part body 310, and the relative positions of the first antenna part 410 and the second antenna part 420 can be flexibly adjusted to meet different smart terminals and NFC communication requirements.

[0066] Optionally, the length of the first antenna portion 410 is less than the length of the second antenna portion 420. In this embodiment, the performance of the NFC antenna can be optimized by adjusting the length ratio of the first antenna portion 410 and the second antenna portion 420. Optionally, when the side where the first antenna portion 410 is located is used to interact with the external device 700 to achieve on-site communication, and the length of the first antenna portion 410 is less than the length of the second antenna portion 420, the first antenna portion 410, as the main radiation part, can better receive and transmit NFC signals and improve the coverage and penetration of the signal. The second antenna portion 420, as an auxiliary part, can make up for the signal blind area of ​​the first antenna portion 410 in certain directions to a certain extent, and improve the uniformity and stability of the signal. In practical applications, the length ratio of the first antenna portion 410 and the second antenna portion 420 can be flexibly adjusted according to the specific needs of the smart terminal and the design characteristics of the decorative parts. Optionally, when the signal coverage needs to be improved, the length of the first antenna portion 410 can be appropriately increased; and when the production cost or complexity needs to be reduced, the length of the second antenna portion 420 can be appropriately shortened. In addition to the length ratio, factors such as the shape and routing of the first antenna portion 410 and the second antenna portion 420 also affect the performance of the NFC antenna. Therefore, various factors need to be considered comprehensively during the design process to achieve the best performance.

[0067] Optionally, the decorative part body 310 is also provided with an antenna routing area, and the first antenna part 410 and / or the second antenna part 420 are at least partially arranged in the antenna routing area. In this embodiment, the antenna routing area is arranged on the decorative part body 310, which can standardize the layout of the NFC antenna and improve the flexibility and maintainability of the design. The antenna routing area can be a part of the surface of the decorative part body 310, on which a groove or a fixing can be provided to accommodate or fix part or all of the routing of the NFC antenna. The position and shape of the antenna routing area can be flexibly adjusted according to the overall design and performance requirements of the smart terminal. Optionally, the antenna routing area can be set at the edge of the decorative part body 310 to reduce the occupation of the internal space of the smart terminal; or the antenna routing area can be designed as a curved shape to better adapt to the outer contour of the decorative part body 310. In this embodiment, the antenna routing area can be an area inside or on the surface of the decorative part body 310 reserved for the routing of the NFC antenna. When the NFC antenna is routed in the antenna routing area, it can ensure that the antenna signal maintains a stable electric field distribution and magnetic field strength during transmission, thereby ensuring that the NFC antenna will not be affected by external interference or damage during the routing process.

[0068] Optionally, in order to improve the flexibility and scalability of the NFC antenna, the NFC antenna and the antenna wiring area in this embodiment can be modularly arranged. Optionally, the NFC antenna and the antenna wiring area can be designed as independent modules and connected through a standard interface. In this way, when the smart terminal needs to upgrade or expand the NFC communication function, it is only necessary to replace the corresponding module without redesigning and manufacturing the entire smart terminal.

[0069] Optionally, the NFC antenna assembly also includes an NFC module 600 provided on the housing 500, the first end of the NFC antenna is connected to the NFC module 600, and the second end of the antenna is grounded. In this embodiment, the NFC antenna is a single-ended NFC antenna, which is simple and efficient in design and can meet the basic needs of the smart terminal in near-field communication. When at least one end of the NFC antenna is connected to the NFC module 600, at least one through hole 320 can be arranged corresponding to the NFC module 600 so that the NFC antenna can smoothly penetrate the decorative part body 310. As the control core of the NFC antenna, the NFC module 600 is responsible for signal modulation, demodulation and communication protocol processing with other NFC devices. Through the NFC module 600, the smart terminal can read and write NFC tags, exchange data with other NFC devices, and complete various applications based on NFC technology. In this embodiment, the first end of the NFC antenna is directly connected to the NFC module 600, ensuring stable transmission and efficient processing of the signal. The second end of the NFC antenna is grounded, which can effectively eliminate the accumulation of static electricity on the antenna and prevent the influence of static electricity on the performance of the NFC antenna. In addition, grounding can also improve the radiation efficiency of the antenna and increase the coverage range of the NFC signal.

[0070] In this embodiment, the NFC antenna assembly includes an NFC antenna and a decorative part, and the first antenna part 410 and the second antenna part 420 of the NFC antenna are arranged on both sides of the decorative part body 310, so that the first antenna part 410 or the second antenna part on one side of the decorative part body 310 can directly interact with the external device 700 to realize the near field communication function, thereby reducing the NFC magnetic field absorbed by the NFC antenna due to the covering of the decorative part. At the same time, since the first antenna part 410 or the second antenna part 420 directly interacts with the external device 700, there is no decorative part blocking the two, which effectively solves the problem of the short interaction distance between the NFC antenna and the external device 700 caused by the thickness of the decorative part. The present application is conducive to improving the performance of the NFC antenna, increasing the interaction distance of the NFC of the smart terminal, and improving the user experience of the NFC function.

[0071] Third embodiment

[0072] Based on any of the solutions in the above embodiments, the present application also provides a smart terminal, referring to Figure 4 , Figure 4 This is a schematic diagram of the structure of a smart terminal according to an embodiment of the present application. The smart terminal includes an NFC antenna component, and the specific structure of the NFC antenna component refers to the above embodiment.

[0073] Optionally, the smart terminal includes a housing 500, and the NFC antenna assembly is arranged on one side of the housing 500. The housing 500 can be made of various materials, such as plastic, metal or composite materials. In terms of structural design, the housing 500 can be designed in various shapes and sizes to meet the layout requirements of the internal space of the smart terminal. Optionally, the NFC antenna can be engraved on the housing 500 by using laser engraving technology; the NFC antenna can also be formed by metal cutting, stamping and other processes, and then fixed on the housing 500; optionally, the NFC antenna can also be fixed on the housing 500 by welding, pasting or other methods to ensure its stability and reliability. At the same time, the decorative parts can also be tightly connected to the housing 500 by corresponding fixing methods, such as buckles, screws or glue, etc., to prevent loosening or falling off during use.

[0074] Optionally, the housing 500 includes a bottom shell and a frame; the decorative component is disposed on the bottom shell, a portion of the NFC antenna is disposed on the bottom shell, and another portion of the NFC antenna is disposed on the frame.

[0075] In this embodiment, the bottom shell is the bottom component of the housing 500, which is used to carry and protect the hardware components inside the smart terminal, such as the motherboard, battery, camera module, etc. The frame is the side component of the housing 500, which is used to surround and fix the bottom shell, and also provides support for the screen. Sometimes, external interfaces such as volume keys, power keys, and SIM card slots are integrated. In this embodiment, a part of the NFC antenna is set on the bottom shell, and another part of the NFC antenna is set on the frame, so that the main radiation area of ​​the NFC antenna avoids the area where the decorative parts are located, which not only avoids the influence of the decorative parts, but also makes full use of the space of the frame to ensure the performance of the NFC antenna. Specifically, a part of the antenna bypasses the decorative parts and extends to the inside of the frame through the connection between the bottom shell and the frame, so that the NFC antenna can avoid the metal decorative parts as much as possible, thereby reducing signal loss and ensuring the normal use of the NFC function. At the same time, by setting part of the routing of the NFC antenna inside the frame, the space can be effectively utilized, and it will not cause too much interference to the internal layout of the smart terminal, which helps to achieve the light and thin design of the smart terminal. Such a design can also ensure the stability of the NFC antenna, reduce the performance instability caused by frequent movement or collision, and improve the user experience of the smart terminal.

[0076] Optionally, the decorative element is disposed on the housing 500, and the NFC antenna is disposed on the side of the decorative element away from the housing 500. By disposing the NFC antenna on the side of the decorative element away from the housing 500, direct interaction between the NFC antenna and the external device 700 is achieved, and signal attenuation that may be caused by the covering of the NFC antenna by the decorative element is reduced. This design is particularly suitable for smart terminals that need to frequently use the NFC function, such as smart phones, tablet computers, etc.

[0077] In this embodiment, the NFC antenna assembly includes an NFC antenna and a decorative part, and the first antenna part 410 and the second antenna part 420 of the NFC antenna are arranged on both sides of the decorative part body 310, so that the first antenna part 410 or the second antenna part on one side of the decorative part body 310 can directly interact with the external device 700 to realize the near field communication function, thereby reducing the NFC magnetic field absorbed by the NFC antenna due to the covering of the decorative part. At the same time, since the first antenna part 410 or the second antenna part 420 directly interacts with the external device 700, there is no decorative part blocking the two, which effectively solves the problem of the short interaction distance between the NFC antenna and the external device 700 caused by the thickness of the decorative part. The present application is conducive to improving the performance of the NFC antenna, increasing the interaction distance of the NFC of the smart terminal, and improving the user experience of the NFC function.
