Description

Technical Field

[0001] This application relates to the field of communication technology, specifically to an electronic device. Background Technology

[0002] Currently, NFC (Near Field Communication) antennas in electronic devices such as mobile phones use a purely shared antenna design, making them highly dependent on cellular antenna solutions. However, changes in the cellular antenna design due to the mobile phone's structural design further impact the antenna performance of NFC antennas. Summary of the Invention

The conductor is electrically connected to the non-near-field communication antenna so that at least a portion of the non-near-field communication antenna cooperates with the conductor to become a near-field communication radiator. The first radiator is configured as part of the near-field communication radiator, and the conductor includes a first radiating portion closest to the first radiator.

[0007] The near-field communication chip has a first differential signal terminal and a second differential signal terminal that are electrically connected to the near-field communication radiator, respectively.

[0046] The display screen 10 may be a liquid crystal display (LCD) or an organic light-emitting diode (OLED) display screen, etc., for displaying information or images. In some embodiments, the display screen 10 may be omitted.

[0047] The material of the mid-frame component 20 can be magnesium alloy, aluminum alloy, stainless steel, or other metals. Of course, the material is not limited to these and can also be other materials.

[0048] The mid-frame assembly 20 can be positioned between the display screen 10 and the battery cover 30. The mid-frame assembly 20 can be used to support the display screen 10. The connection between the mid-frame assembly 20 and the battery cover 30 can form the outer contour of the electronic device 100, and an internal receiving space 101 can be formed to accommodate electronic components such as the circuit board 40, the rear camera 50, the front camera, the speaker, the processor, and various types of sensors. The mid-frame assembly 20 and the battery cover 30 can cooperate to form a housing 102. Of course, the housing 102 is not limited to the form formed by the cooperation of the mid-frame assembly 20 and the battery cover 30, and can also be in other forms. In some embodiments, the housing 102 can support the display screen 10 on its surface.

[0049] The mid-frame assembly 20 may include a substrate 21 for supporting the display screen 10 and a frame 22 surrounding the substrate 21. The substrate 21 may be disposed opposite to the battery cover 30. The frame 22 may be fastened to the battery cover 30 by means of bonding, welding, snap-fitting, etc. That is, the substrate 21, frame 22, and battery cover 30 enclose a receiving space 101. In some embodiments, the substrate 21 may be omitted, and the frame 22 and battery cover 30 enclose the receiving space 101. In some embodiments, the substrate 21 may be omitted, and the display screen 10 may be fixed to the frame 22. In some embodiments, the substrate 21 may be omitted, and the circuit board 40 may be fixed within the receiving space 101. In some embodiments, the frame 22 and the battery cover 30 are an integral structure. For example, the frame 22 may extend from the edge of the battery cover 30 towards the side closer to the display screen 10.

[0050] The frame 22 can be made of a conductive metal, so it can also be called a "metal frame". Of course, the frame 22 can also be made of other conductive materials, or it can be made of a non-conductive material. The shape of the frame 22 can be circular, rectangular, or other shapes. The frame 22 may include a first frame 221, a second frame 222, a third frame 223, and a fourth frame 224 connected end-to-end. The first frame 221, the second frame 222, the third frame 223, and the fourth frame 224 can surround the substrate 21 and the circuit board 40 and can be connected and fixed to the substrate 21. It is understood that the frame 22 is not limited to the first frame 221, the second frame 222, the third frame 223, and the fourth frame 224; the frame 22 can be adjusted according to its shape, such as circular, polygonal, or irregular shapes.

[0051] The terms "first," "second," "third," etc., used in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," "third," etc., may explicitly or implicitly include at least one of those features.

[0052] In some embodiments, the first border 221, the second border 222, the third border 223, and the fourth border 224 form a rounded rectangle. Of course, other shapes such as circles or triangles can also be used. In some embodiments, the first border 221 and the third border 223 are positioned opposite each other, and the second border 222 and the fourth border 224 are positioned opposite each other.

[0053] In some embodiments, the first frame 221, the second frame 222, the third frame 223 and the fourth frame 224 may be fixedly connected to the display screen 10 to achieve a fixed connection between the frame 22 and the display screen 10.

[0054] In some embodiments, the lengths of the first border 221 and the third border 223 are both shorter than the length of the second border 222 and both are shorter than the length of the fourth border 224.

[0055] The battery cover 30 can be made of the same material as the mid-frame assembly 20, or other materials. The battery cover 30 can be integrally formed with the mid-frame assembly 20. In some embodiments, the battery cover 30 can enclose the mid-frame assembly 20 and support the display screen 10. Structures such as a rear camera hole and a fingerprint recognition module mounting hole can be formed on the battery cover 30.

[0056] Please see Figure 1 and Figure 2 , Figure 2 for Figure 1 A view of the electronic device 100 viewed from the side of the battery cover 30. The battery cover 30 covers the side of the mid-frame assembly 20 away from the display screen 10 and can be connected to the frame 22, such as the first frame 221, the second frame 222, the third frame 223 and the fourth frame 224, and is disposed opposite to the substrate 21.

[0057] In some embodiments, the battery cover 30 is provided with a camera metal decorative piece 31 to cooperate with the rear camera 50. In some embodiments, the camera metal decorative piece 31 is located at the portion of the battery cover 30 that connects to the first frame 221 and at the portion of the battery cover 30 that connects to the fourth frame 224.

[0058] Please see Figure 1 The circuit board 40 is installed within the receiving space 101 and can be installed at any position within the receiving space 101. The circuit board 40 can be the motherboard of the electronic device 100. The processor of the electronic device 100 can be located on the circuit board 40. The circuit board 40 can also integrate one, two, or more functional components such as a motor, microphone, speaker, receiver, headphone jack, universal serial bus interface (USB interface), front camera, rear camera 50, distance sensor, ambient light sensor, and gyroscope. Meanwhile, the display screen 10 can be connected to the circuit board 40. In some embodiments, the circuit board 40 is sandwiched between the substrate 21 and the battery cover 30.

[0059] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0060] Please see Figure 3 , Figure 3 for Figure 1The electronic device 100 is viewed from one side of the battery cover 30 in another embodiment. The electronic device 100 may also include a non-near-field communication antenna 60 and a near-field communication antenna 70. The non-near-field communication antenna 60 and / or the near-field communication antenna 70 cooperate to enable communication with external devices.

[0061] The non-near-field communication antenna 60 may include one or more of the following: a cellular antenna, a Wireless Fidelity (Wi-Fi) antenna, a Global Positioning System (GPS) antenna, and a Bluetooth (BT) antenna. The near-field communication antenna 70 employs NFC (Near Field Communication) technology. NFC is a very short-range radio frequency identification (RFID) communication protocol standard; NFC signals have a small transmission range but fast transmission speed and low energy efficiency. By incorporating NFC communication functionality into the electronic device 100, it can function as an airport boarding pass, access key, transportation card, credit card, and payment card.

[0062] It should be noted that in the non-near-field communication antenna 60, the signal frequency of the cellular antenna can be above 700MHz, the signal frequency of the Wi-Fi antenna can include 2.4GHz (Gigahertz) or 5GHz, the signal frequency of the GPS antenna can include one or more frequency bands such as 1.575GHz, 1.227GHz, 1.381GHz, and 1.841GHz, and the signal frequency of the Bluetooth antenna can include 2.4GHz. The signal frequency of the near-field communication antenna 70 can include 13.56MHz (Mahhertz). Therefore, compared to the cellular antenna, Wi-Fi antenna, GPS antenna, and Bluetooth antenna, the signal of the near-field communication antenna 70 is a low-frequency signal, while the signals of the cellular antenna, Wi-Fi antenna, GPS antenna, and Bluetooth antenna are all high-frequency signals. This can be understood as the signal of the non-near-field communication antenna 60 being a high-frequency signal, and the signal of the near-field communication antenna 70 being a low-frequency signal. The signal frequency of the non-near-field communication antenna 60 is higher than the signal frequency of the near-field communication antenna 70. Therefore, the non-near-field communication antenna 60 can also be a high-frequency antenna with other high-frequency signals.

[0063] In some embodiments, the cellular antenna operates in the frequency band of 1710MHz-6000MHz for fourth-generation mobile communication technology (4G) and 5G communication in electronic devices.

[0064] Please see Figure 3The non-near-field communication antenna 60 can be disposed on the housing 102. The non-near-field communication antenna 60 can be one or more of the following: a flexible printed circuit (FPC) antenna, a laser direct-structuring (LDS) antenna, a printed direct-structuring (PDS) antenna, and a metal frame antenna. Of course, the non-near-field communication antenna 60 can also be other types of antennas, which will not be elaborated upon. This application uses a metal frame antenna as an example for illustration.

[0065] Please see Figure 4 , Figure 4 for Figure 3 This is a schematic diagram showing the structure of the mid-frame assembly 20, circuit board 40, non-near-field communication antenna 60, and near-field communication antenna 70 in cooperation. The non-near-field communication antenna 60 may include at least a first radiator 61 at least partially disposed on a frame 22, such as a first frame 221, and a second radiator 62 at least partially disposed on a frame 22, such as a second frame 222. The first radiator 61 may be one or more of a cellular antenna, a Wi-Fi antenna, a GPS antenna, or a Bluetooth antenna. The second radiator 62 may be one or more of a cellular antenna, a Wi-Fi antenna, a GPS antenna, or a Bluetooth antenna. In some embodiments, the effective electrical length of the first radiator 61 is 10 mm.

[0066] In some embodiments, the first radiator 61 may be partially disposed on the frame 22, such as the first frame 221, or partially disposed on the frame 22, such as the fourth frame 224. In some embodiments, the first radiator 61 may extend partially in the extending direction of the first frame 221 or partially in the extending direction of the fourth frame 224.

[0068] Please see Figure 4 and Figure 5 , Figure 5 for Figure 4 A schematic diagram of the structure of the near-field communication antenna 60 and near-field communication antenna 70 in conjunction with each other. A first wiring portion 6101 and a second wiring portion 6102 may be provided on the first radiator 61. The cooperative arrangement of the first wiring portion 6101 and the second wiring portion 6102 enables the excitation signal to flow on the first radiator 61.

In some embodiments, the first radiator 61 may be arranged side by side with the orthographic projection of the camera metal decorative element 31 onto the frame 22, such as the first frame 221. In some embodiments, the first radiator 61 may be closer to the side of the second frame 222 than the orthographic projection of the camera metal decorative element 31 onto the frame 22, such as the first frame 221, thereby reducing the impact of the camera metal decorative element 31 on the antenna performance of the first radiator 61. In some embodiments, the orthographic projection of the camera metal decorative element 31 onto the frame 22, such as the first frame 221, may be located on the side of the first radiator 61 closer to the fourth frame 224. That is, the first radiator 61 may be located on the side of the orthographic projection of the camera metal decorative element 31 onto the frame 22, such as the first frame 221, closer to the second frame 222.

[0072] In some embodiments, the second radiator 62 may be partially disposed on the frame 22, such as the first frame 221, or partially disposed on the frame 22, such as the second frame 222. In some embodiments, the second radiator 62 may extend partially in the extending direction of the first frame 221 or partially in the extending direction of the second frame 222.

[0073] In some embodiments, the second radiators 62 may be entirely disposed on the frame 22, such as the second frame 222. In some embodiments, the second radiators 62 extend entirely in the extending direction of the second frame 222.

[0074] Please see Figure 4 and Figure 5A third wiring portion 6201 and a fourth wiring portion 6202 may be provided on the second radiator 62. The cooperative arrangement of the third wiring portion 6201 and the fourth wiring portion 6202 enables the excitation signal to flow on the second radiator 62.

[0075] In some embodiments, the third terminal 6201 can be used for grounding, and is therefore also referred to as a grounding terminal. In some embodiments, the third terminal 6201 can be used for electrical connection to a feed source, and is therefore also referred to as a power supply terminal. In some embodiments, the third terminal 6201 is neither electrically connected to a feed source nor grounded. In some embodiments, the fourth terminal 6202 can be used for electrical connection to a feed source, and is therefore also referred to as a power supply terminal. In some embodiments, the fourth terminal 6202 can also be used for grounding, and is therefore also referred to as a grounding terminal. In some embodiments, the fourth terminal 6202 is neither electrically connected to a feed source nor grounded.

[0076] In some embodiments, the third wiring portion 6201 is closer to the first frame 221 than the fourth wiring portion 6202. That is, the fourth wiring portion 6202 is closer to the third frame 223 than the third wiring portion 6201.

[0077] In some embodiments, the second radiator 62 may include a first radiating branch 621 disposed on a frame 22, such as a first frame 221, and a second radiating branch 622 disposed on a frame 22, such as a second frame 222. The first radiating branch 621 and the second radiating branch 622 may be connected at the location where the first frame 221 and the second frame 222 are connected.

[0078] In some embodiments, the first radiating branch 621 and the second radiating branch 622 may be grounded at the location where the first frame 221 and the second frame 222 are connected. In some embodiments, a third wiring portion 6201 may be provided on the first radiating branch 621. In some embodiments, a fourth wiring portion 6202 may be provided on the second radiating branch 622. In some embodiments, the effective electrical length of the second radiating branch 622 is 26 mm.

[0079] Please see Figure 3 The near-field communication antenna 70 may include a first radiator 61, a second radiator 62, a conductor 71, and a near-field communication chip 72. The near-field communication antenna 70 may not be limited to the first radiator 61 and the second radiator 62, and may also include other parts of the non-near-field communication antenna 60, which will not be elaborated upon here.

[0080] Conductor 71 cooperates with at least a portion of the non-near-field communication antenna 60, such as the first radiator 61 and the second radiator 62, to form a near-field communication radiator. The near-field communication antenna 70 and the non-near-field communication antenna 60 share the radiator, which can improve the antenna performance of the near-field communication antenna 70 while saving space 101. The near-field communication chip 72 is used to provide a differential excitation current to excite the near-field communication radiator. The differential excitation current includes two current signals. The two current signals have the same amplitude and opposite phase, or can be understood as having a phase difference of 180 degrees. Furthermore, the differential excitation current is a balanced signal. It can be understood that if an analog signal is directly transmitted during transmission, it is an unbalanced signal; if the original analog signal is inverted and then the inverted analog signal and the original analog signal are transmitted simultaneously, the inverted analog signal and the original analog signal are called balanced signals. During transmission, the balanced signal passes through a differential amplifier. The original analog signal is subtracted from the inverted analog signal to obtain a stronger original analog signal. Since the two transmission lines are subjected to the same interference during transmission, the same interference signal is subtracted during the subtraction process. Therefore, the balanced signal has better anti-interference performance.

[0081] Please see Figure 4 The conductor 71 may be disposed on the circuit board 40. Specifically, it may be located on the side of the circuit board 40 facing the battery cover 30. In some embodiments, the conductor 71 may be a conductive plating layer formed by metal plating on the surface of the circuit board 40, thereby forming on the surface of the circuit board 40 facing the battery cover 30. In some embodiments, the conductor 71 may be a flexible circuit board disposed on the circuit board 40. In some embodiments, the conductor 71 may be a laser-direct-formed conductor disposed on the circuit board 40 using laser direct forming technology. In some embodiments, the conductor 71 may be a printed direct-formed conductor disposed on the circuit board 40 using printed direct forming technology.

[0082] Please see Figure 5 The conductor 71 may have a wiring portion 7101 and a wiring portion 7102. In some embodiments, the wiring portion 7101 and the wiring portion 7102 may be located at both ends of the conductor 71 in the extending direction. Of course, the wiring portion 7101 and the wiring portion 7102 may also be provided at other parts of the conductor 71.

[0083] Please see Figure 4 The conductor 71 is disposed on the side of the circuit board 40 near the first frame 221, spaced apart from the first frame 221, thereby making full use of the clearance area between the circuit board 40 and the first frame 221. The clearance area refers to the area configured so that magnetic lines of force can pass through smoothly without being excessively affected or obstructed.

[0084] Please see Figure 3The orthographic projection of the conductor 71 on the first frame 221 is located on the side of the first radiator 61 closer to the second frame 222, and is spaced apart from the first radiator 61. This allows the first radiator 61 and the conductor 71 to perform near-field communication together, increasing the length of the near-field communication radiator in the extension direction of the first frame 221, thereby enhancing antenna performance. Of course, the orthographic projection of the conductor 71 on the first frame 221 and the first radiator 61 can also be arranged intersecting, and the conductor 71 can be closer to the second frame 222 than the first radiator 61.

[0085] In some embodiments, the effective electrical length of the conductor 71 is 28 mm, which, in conjunction with the first radiating branch 621, makes the effective electrical length of the near-field communication radiator on the first frame 221 the sum of 28 mm and 10 mm, specifically 38 mm, which is greater than 35 mm. This enhances the antenna performance and can compensate for the low antenna performance caused by the short effective electrical length of the first radiator 61 due to the metal decorative part 31 of the camera.

[0086] The orthographic projection of the conductor 71 on the first frame 221 can be intersected with the second radiator 62, and is closer to the fourth frame 224 than the second radiator 62. Alternatively, the orthographic projection of the conductor 71 on the first frame 221 can be located on the side of the second radiator 62 closest to the fourth frame 224, and spaced apart from the second radiator 62. This allows the second radiator 62, for example, the first radiating stub 621, to perform near-field communication together with the conductor 71, increasing the length of the near-field communication radiator in the extension direction of the first frame 221, thereby enhancing antenna performance.

[0087] The orthographic projection of the conductor 71 on the battery cover 30 is located on the side of the camera metal decorative piece 31 closer to the second frame 222, thereby reducing the impact of the camera metal decorative piece 31 on the antenna performance of the conductor 71. Of course, the orthographic projection of the conductor 71 on the battery cover 30 and the camera metal decorative piece 31 can also be arranged alternately, and the conductor 71 can be closer to the second frame 222 than the camera metal decorative piece 31.

[0088] Please see Figure 4 and Figure 6 , Figure 6 for Figure 4 A view of the electronic device 100 viewed from one side of the battery cover 30. The conductor 71 may be located on the side of the front-facing camera 80 near the second bezel 222. Alternatively, the conductor 71 may be located on the side of the front-facing camera 80 near the fourth bezel 224.

[0089] This is understandable; please refer to [link / reference]. Figure 4The front-facing camera 80 may be part of the electronic device 100 and disposed within the receiving space 101. In some embodiments, the circuit board 40 may have a first clearance space 401 to make way for the front-facing camera 80, such that the front-facing camera 80 is placed within the first clearance space 401. In some embodiments, the front-facing camera 80 may be disposed on the circuit board 40.

[0090] Please see Figure 4 and Figure 6 The conductor 71 may be located around the speaker 90. In some embodiments, the conductor 71 may be partially located on the side of the speaker 90 near the first frame 221 and partially located on the side of the speaker 90 away from the second frame 222. In some embodiments, the conductor 71 may be partially located on the side of the speaker 90 near the first frame 221 and partially located on the side of the speaker 90 near the second frame 222. In some embodiments, the conductor 71 may be partially located on the side of the speaker 90 near the first frame 221, partially located on the side of the speaker 90 away from the second frame 222, and partially located on the side of the speaker 90 near the second frame 222.

[0091] This is understandable; please refer to [link / reference]. Figure 4 The speaker 90 may be part of the electronic device 100 and disposed within the receiving space 101. In some embodiments, the circuit board 40 may have a second clearance space 402 to accommodate the speaker 90, such that the speaker 90 is placed within the second clearance space 402. In some embodiments, the speaker 90 may be disposed on the circuit board 40. In some embodiments, the second clearance space 402 is located on the side of the first clearance space 401 that is closer to or farther from the second frame 222. In some embodiments, the speaker 90 is closer to the second frame 222 than the front-facing camera 80. In some embodiments, the front-facing camera 80 is closer to the second frame 222 than the speaker 90. In some embodiments, the speaker 90 is located on the side of the front-facing camera 80 that is closer to the second frame 222. In some embodiments, the front-facing camera 80 is located on the side of the speaker 90 that is closer to the second frame 222.

[0092] Please see Figure 4The conductor 71 may include a first radiating portion 711 and a second radiating portion 712 connected to each other. In some embodiments, the extending directions of the first radiating portion 711 and the second radiating portion 712 are perpendicular to each other, but they may not be perpendicular. In some embodiments, the extending direction of the first radiating portion 711 may be consistent with the extending direction of the first frame 221. In some embodiments, the extending direction of the second radiating portion 712 may be consistent with the extending direction of the second frame 222. In some embodiments, the first radiating portion 711 is closer to the first frame 221 than the second radiating portion 712. Therefore, the first radiating portion 711, together with the first radiator 61 and / or the second radiator 62 (e.g., the first radiating stub 621), can increase the radiating area of ​​the near-field communication antenna 70, thereby improving the radiation capability of the near-field communication antenna 70. In some embodiments, the second radiating portion 712 is closer to the second frame 222 than the first radiating portion 711. Therefore, the second radiating portion 712, together with the second radiator 62 (e.g., the second radiating stub 622), can increase the radiating area of ​​the near-field communication antenna 70, thereby improving the radiation capability of the near-field communication antenna 70. In some embodiments, the second radiating portion 712 is closer to the fourth frame 224 than the first radiating portion 711. In some embodiments, the first radiating portion 711 is disposed on the side of the speaker 90 closer to the first frame 221. In some embodiments, the second radiating portion 712 is disposed between the front-facing camera 80 and the speaker 90. In some embodiments, the second radiating portion 712 may be omitted. In some embodiments, the second radiating portion 712 is disposed between the first clearance space 401 and the second clearance space 402. In some embodiments, the second radiating portion 712 is disposed on the side of the second clearance space 402 away from the first clearance space 401.

[0093] Please see Figure 5 A connecting portion 7102 is provided on the first radiating portion 711. A connecting portion 7101 is provided on the second radiating portion 712. In some embodiments, the connecting portion 7101 is located at the end of the second radiating portion 712 away from the first radiating portion 711. In some embodiments, the connecting portion 7102 is located at the end of the first radiating portion 711 away from the second radiating portion 712.

[0094] Please see Figure 7 , Figure 7 for Figure 3 A schematic diagram of the frame of the near-field communication antenna 70. The near-field communication chip 72 has a first differential signal terminal 721 and a second differential signal terminal 722 that are electrically connected to the near-field communication radiator, respectively. The first differential signal terminal 721 and the second differential signal terminal 722 are used to provide differential excitation current to excite the near-field communication radiator.

[0095] In some embodiments, the first radiator 61, the conductor 71, and the second radiator 62, such as the first radiating branch 621 and the second radiating branch 622, are connected in series to form a near-field communication radiator.

In some embodiments, the first wiring portion 6101 is electrically connected to one end of the tuning circuit 73, and the other end of the tuning circuit 73 is grounded, so that the first wiring portion 6101 is grounded through the tuning circuit 73, thereby the first wiring portion 6101 serves as a grounding portion. It is understood that the tuning circuit 73 may be part of the non-near-field communication antenna 60 and / or the near-field communication antenna 70.

[0097] In some embodiments, the tuning circuit 73 may consist of a switch control circuit and / or a load circuit, or an adjustable capacitor (which may also be replaced by a fixed capacitor) and / or an adjustable inductor, specifically adjustable as needed.

In some embodiments, the tuning circuit 73 may include a capacitor C1. One end of the capacitor C1 is grounded, and the other end is electrically connected to the first terminal 6101. The capacitor C1 is configured in two ways. It is understood that the tuning circuit 73, for example, the capacitor C1, effectively reduces the mutual influence between the non-near-field communication antenna 60 and the near-field communication antenna 70, and for the differential excitation current of the near-field communication antenna 70, since the tuning circuit 73, for example, the capacitor C1, has an isolation effect on low-frequency signals, the differential excitation current of the near-field communication antenna 70 does not return to ground.

[0098] In some embodiments, the capacitance of capacitor C1 may be 100pF.

[0122] Understandably, this application improves the antenna performance of the camera metal decorative part 31 when the first radiator 61 is reused as a near-field communication radiator. The conductor 71 mitigates the impact of excessive effective electrical length of the first radiator 61 on antenna performance, and further reduces the dependence of the near-field communication antenna 70 on the length of the first radiator 61. The design of the conductor 71 on the circuit board 40 reduces the constraints of the near-field communication antenna 70 on the structural design of the electronic device 100. In this application, the near-field communication radiator encloses a larger area, thereby significantly increasing the magnetic flux.

[0123] Please see Figure 8 , Figure 8 for Figure 3The diagram illustrates the structure of the mid-frame assembly 20, circuit board 40, non-near-field communication antenna 60, and near-field communication antenna 70 in another embodiment.
