[0025] The following is combined Figures 1 to 7 This application describes an electronic device according to an embodiment of the present application.

[0026] like Figure 1 and Figure 2 As shown in the figure, this application provides an electronic device, which includes a circuit board 10, a display screen 30, and a conductive frame 20. The circuit board 10 and the display screen 30 are stacked, and the conductive frame 20 is disposed between the circuit board 10 and the display screen 30. The conductive frame 20 includes a first radiator 1 and a second radiator 2. The first radiator 1 includes a first feed terminal 11 and a first ground terminal 12 that are electrically connected. The first feed terminal 11 is connected to the circuit board 10. The circuit board 10 is used to excite the first radiator 1 to generate resonance in a first frequency band. The second radiator 2 includes a second feed terminal 21 that is connected to the circuit board 10. The circuit board 10 is used to excite the second radiator 2 to generate resonance in a second frequency band. The projections of the first ground terminal 12 and the second feed terminal 21 in the projection direction of the display screen 30 at least partially overlap.

[0027] The electronic devices provided in this application can be mobile phones, tablets, laptops, PDAs, in-vehicle electronic devices, mobile internet devices (MIDs), augmented reality / virtual reality devices, wearable devices, etc., and the embodiments in this application are not specifically limited. The following description uses a mobile phone as an example of an electronic device.

[0028] The conductive frame 20 can be a cuboid, having two oppositely arranged short-axis sidewalls and two oppositely arranged long-axis sidewalls. The user can apply force to the long-axis sidewalls to hold the electronic device. The first radiator 1 and the second radiator 2 can reuse either of the two short-axis sidewalls; that is, the short-axis sidewall can serve as both the frame and antenna of the electronic device. This reuse of the short-axis sidewalls reduces or prevents the user's hand from obstructing the first radiator 1 and the second radiator 2 when holding the electronic device.

[0029] Optionally, the circuit board 10, the conductive frame 20, and the display screen 30 are stacked sequentially along the first direction X.

[0030] The projection direction of the first grounding terminal 12 and the second power supply terminal 21 on the display screen 30 can be the first direction.

[0031] The first direction can also be the thickness direction of the electronic device.

[0032] The first radiator 1 and the second radiator 2 can be used for communication in different frequency bands and with different protocols. That is, the first frequency band and the second frequency band are different, and the communication protocols used by the first radiator 1 and the second radiator 2 are different. For example, the first radiator 1 can be used to implement near-field communication (NFC), and the second radiator 2 can be used to implement cellular communication. Near-field refers to radio waves in the vicinity of an electromagnetic field. NFC communication can be wireless communication based on NFC protocols, or it can be based on other protocols, such as wireless communication based on RFID protocols. Cellular communication can be communication with 2G / 3G / 4G / 5G cellular mobile networks. For another example, the first radiator 1 can be used to implement NFC communication in NFC, and the second radiator 2 can be used to implement Wi-Fi communication in NFC.

[0033] The first radiator 1 can be a single-piece molded component. The first radiator 1 is electrically connected to the circuit board 10 through the first power supply terminal 11 and grounded through the first grounding terminal 12. The second radiator 2 can be a single-piece molded component. The second radiator 2 is electrically connected to the circuit board 10 through the second power supply terminal 21.

[0034] The projections of the first grounding terminal 12 onto the display screen 30 and the second power supply terminal 21 onto the display screen 30 at least partially overlap, allowing the first radiator 1 and the second radiator 2 to share a portion of the conductive frame 20, thereby ensuring that both the first radiator 1 and the second radiator 2 have sufficient length. Optionally, when the first radiator 1 and / or the second radiator 2 are used to implement NFC communication, the first radiator 1 and / or the second radiator 2 can be set to a sufficient length as needed. The projections of the first grounding terminal 12 onto the display screen 30 and the second power supply terminal 21 onto the display screen 30 at least partially overlap, that is, the portion of the first radiator 1 used for grounding and the portion of the second radiator 2 used for power supply connection with the circuit board 10 at least partially overlap, thereby reducing the coupling effect between the first grounding terminal 12 and the second power supply terminal 21.

[0035] For example, the first radiator 1 and the second radiator 2 reuse the short axis sidewall of the conductive frame 20. The overlapping part of the projection of the first radiator 1 and the projection of the second radiator 2 can share the length of a short axis sidewall of the conductive frame 20. That is, when the width of the conductive frame 20 remains unchanged, the first radiator 1 and the second radiator 2 have a longer length along the width direction of the conductive frame 20.

[0036] It is understood that the length of the first radiator 1, the length of the second radiator 2, the width and length of the gap between the first radiator 1 and the second radiator 2 will all affect the performance of the first radiator 1 and the second radiator 2, and those skilled in the art can determine them according to specific needs.

[0037] In the electronic device provided in this application, the projection of the first grounding terminal 12 on the display screen 30 and the projection of the second power supply terminal 21 on the display screen 30 at least partially overlap, so that the portions of the first radiator 1 and the second radiator 2 that are spaced apart can share a portion of the conductive frame 20, ensuring the effective length of the first radiator 1 and the second radiator 2 in a limited space and improving space utilization.

[0038] In some embodiments, the first ground terminal 12 is disposed on the side of the second power supply terminal 21 near the display screen 30.

[0039] The circuit board 10, the second power supply terminal 21, the first ground terminal 12, and the display screen 30 can be arranged sequentially at intervals along the first direction X. The first ground terminal 12 in the first radiator 1, which is used for grounding, is closer to the display screen 30 than the second power supply terminal 21 in the second radiator 2, which is used for connecting to the circuit board 10. Due to the influence of the display screen 30, the area near the display screen 30 has poor clearance. Compared to placing the first power supply terminal 11 in this area, placing the first ground terminal 12 in this area can improve the performance of the first radiator 1. Furthermore, since the first ground terminal 12 is placed in this area, the second power supply terminal 21, which is spaced apart from the first ground terminal 12, can be moved away from the display screen 30, thereby improving the performance of the second radiator 2.

[0040] By setting the first ground terminal 12 closer to the display screen 30 than the second power supply terminal 21, the performance of the first radiator 1 and the second radiator 2 is improved.

[0041] In some embodiments, the resonance of the first frequency band is the NFC communication resonance, and the resonance of the second frequency band is the cellular communication resonance.

[0042] When a user answers a phone call using an electronic device, the device is close to the user's head, and the device establishes communication with the base station through resonance in the second frequency band. The resonance in the second frequency band generated by the second radiator 2 is detrimental to the user's health. However, the first radiator 1, positioned near the display screen 30, can shield part of the second frequency band resonance, thereby reducing its effect on the user. In one embodiment, the electronic device using the aforementioned embodiment can reduce the specific absorption rate of the second frequency band resonance to the user's head by 30%.

[0043] In some embodiments, at least one of the first ground terminal 12 and the second power supply terminal 21 has a clearance opening. When the first ground terminal 12 has a clearance opening, at least a portion of the second power supply terminal 21 is located within the clearance opening. When the second power supply terminal 21 has a clearance opening, at least a portion of the first ground terminal 12 is located within the clearance opening.

[0044] This application includes the following:

[0045] When the first grounding terminal 12 has a clearance opening and the second power supply terminal 21 does not have a clearance opening, at least a portion of the second power supply terminal 21 is located within the clearance opening.

[0046] When the second power supply terminal 21 has a clearance opening and the first grounding terminal 12 does not have a clearance opening, at least a portion of the first grounding terminal 12 is located within the clearance opening.

[0047] When the first grounding terminal 12 has a clearance opening and the second power supply terminal 21 has a clearance opening, at least a portion of the second power supply terminal 21 is located within the clearance opening of the first grounding terminal 12, and at least a portion of the first grounding terminal 12 is located within the second power supply terminal 21.

[0048] A first grounding terminal 12 or a second feed terminal 21 with a clearance opening can be formed by thinning a portion of the first radiator 1 and a portion of the second radiator 2. By providing the clearance opening, all or part of the first grounding terminal 12 and / or the second feed terminal 21 can be accommodated within the clearance opening, thereby reducing the overall thickness of the first grounding terminal 12 and the second feed terminal 21 along the first direction X.

[0049] In one embodiment, the second radiator 2 further includes a connection terminal 22 spaced apart from the first feed terminal 11 along the second direction Y. The second feed terminal 21 is connected along the second direction Y to the end of the connection terminal 22 near the first feed terminal 11. The first ground terminal 12 is connected along the second direction Y to the end of the first feed terminal 11 near the second feed terminal 21. The first direction X and the second direction Y are intersecting. 。

[0050] The first direction X can be the thickness direction of the electronic device; optionally, the first direction X is the direction from the display screen 30 to the circuit board 10. The second direction Y can be the width or length direction of the electronic device. The first direction X and the second direction Y can be set perpendicularly.

[0051] Connection terminal 22 can be directly used for grounding. If the second radiator 2 has a second grounding terminal for grounding, connection terminal 22 can also be used to connect the second feed terminal 21 and the second grounding terminal. Connection terminal 22 can be directly used for grounding.

[0052] The first power supply terminal 11 and the connection terminal 22 are spaced apart along the second direction Y, so that the first ground terminal 12 and the second power supply terminal 21 can be located between the first power supply terminal 11 and the connection terminal 22, thereby reducing the volume of the entire first radiator 1 and the second radiator 2.

[0053] Please see Figure 3 In some embodiments, the thickness of the first feed terminal 11 along the first direction X is W1, and the thickness of the first ground terminal 12 along the first direction X is W2, where W1 is greater than W2. That is, the first ground terminal 12 has a smaller thickness than the first feed terminal 11, so that the first feed terminal 11 and the first ground terminal 12 connected along the second direction Y form a stepped structure and enclose a first clearance opening. At least a portion of the second feed terminal 21 is disposed within the first clearance opening, and the end face of the second feed terminal 21 facing away from the connection terminal 22 is spaced apart from the end face of the first feed terminal 11 near the connection terminal 22 along the second direction Y.

[0054] In another embodiment, the thickness of the second feed terminal 21 along the first direction X is W3, and the thickness of the connecting terminal 22 along the first direction X is W4. W3 is less than W4, meaning that the second feed terminal 21 has a smaller thickness than the connecting terminal 22. This allows the second feed terminal 21 and the connecting terminal 22, connected along the second direction Y, to form a stepped structure and enclose a second clearance opening. At least a portion of the first ground terminal 12 is disposed within the second clearance opening. The end face of the first ground terminal 12 facing away from the first feed terminal 11 and the end face of the connecting terminal 22 near the first feed terminal 11 are spaced apart along the second direction Y.

[0055] To further reduce the overall thickness of the first radiator 1 and the second radiator 2 along the first direction X, W1 can be set to be equal to W4. When the circuit board 10, the second power supply terminal 21, the first ground terminal 12, and the display screen 30 are spaced apart along the first direction X, the first power supply terminal 11, the second power supply terminal 21, and the connection terminal 22 are all located on the same plane near the surface of the circuit board 10. Conversely, the first power supply terminal 11, the first ground terminal 12, and the connection terminal 22 are all located on the same plane away from the surface of the circuit board 10.

[0056] In one embodiment, the circuit board 10 is also used to excite the first radiator 1 to generate resonance in a third frequency band, the first frequency band and the third frequency band being different.

[0057] The first and third frequency bands are different, allowing the first radiator 1 to simultaneously achieve communication using two different frequency bands and protocols. The first radiator 1 can be used for NFC and non-NFC communication, while the second radiator 2 can be used for non-NFC communication. For example, the first radiator 1 can be used for both Wi-Fi and NFC communication, and the second radiator 2 can be used in conjunction with the first radiator 1 for Wi-Fi communication. Alternatively, the first radiator 1 can be used for both cellular and NFC communication, and the second radiator 2 can be used for Wi-Fi communication.

[0058] like Figure 4 and Figure 5 As shown, in some embodiments, the conductive frame 20 further includes a third radiator 3, which is spaced along the first direction X on the side of the first radiator 1 away from the display screen 30. The first radiator 1 and the third radiator 3 are spaced along the second direction Y from the second radiator 2, and the projection of the third radiator 3 along the first direction X onto the first radiator 1 is spaced apart from the projection of the second radiator 2 along the first direction X onto the first radiator 1.

[0059] The third radiator 3 is electrically connected to the circuit board 10, which is used to excite the third radiator 3 to generate resonance in the third frequency band.

[0060] In this embodiment, a third radiator 3, independent of the first radiator 1, is provided. The third radiator 3, which generates resonance in the third frequency band, and the first radiator 1, which generates resonance in the first frequency band, are each independently powered. Compared with the aforementioned scheme, the independently powered third radiator 3 can avoid mutual interference with the resonance in the first frequency band, thereby eliminating the need for a filtering structure and reducing the resonance losses in the first and second frequency bands. When the first radiator 1 is used to implement NFC communication and the third radiator 3 is used to implement non-NFC communication, the signal isolation inductor loss can be avoided, reducing communication loss.

[0061] In one embodiment, the third radiator 3 includes a third ground terminal 31 and a third feed terminal 32 connected together, with the third feed terminal 32 disposed on the side of the third ground terminal 31 away from the second radiator 2.

[0062] The first feed terminal 11 and the third feed terminal 32 are located on the same side of the first radiator 1 and the third radiator 3, respectively, and the first ground terminal 12 and the third ground terminal 31 are located on the same side of the first radiator 1 and the third radiator 3, respectively. The first feed terminal 11 and the first ground terminal 12 can be arranged along the second direction Y, and the third feed terminal 32 and the third ground terminal 31 can also be arranged along the second direction Y, so that the current flowing through the first radiator 1 and the third radiator 3 has the same direction. This avoids a decrease in local current intensity due to opposite current directions, and prevents a reduction in the effective electrical length of the first radiator 1 and the third radiator 3.

[0063] To meet the performance requirements of the first radiator 1 and the third radiator 3, the first radiator 1 and the third radiator 3 extend along the second direction Y. If the distance between the first radiator 1 and the third radiator 3 along the first direction X is large, higher-order modes of the third frequency band may couple out from the resonance of the first frequency band generated by the first radiator 1, significantly affecting the efficiency of the third radiator 3. Therefore, in some embodiments, the electronic device also includes a first capacitor 5, which is connected to both the first radiator 1 and the circuit board 10. The higher-order modes can be shifted out of the third frequency band through the first capacitor 5.

[0064] Optionally, the first capacitor 5 is connected to the middle of the first radiator 1 along the second direction Y.

[0065] like Figure 6 and Figure 7As shown, this application also provides another electronic device, which includes a conductive frame 20, a stacked circuit board 10, and a display screen 30. The conductive frame 20 is disposed between the circuit board 10 and the display screen 30. The conductive frame 20 includes a first radiator 1 and a second radiator 2. The first radiator 1 includes a first feed terminal 11 and a first ground terminal 12 electrically connected. The second radiator 2 includes a second feed terminal 21 and a second ground terminal 23 electrically connected. The projections of the first feed terminal 11 and the second ground terminal 23 in the projection direction of the display screen 30 at least partially overlap. The projections of the second feed terminal 21 and the first ground terminal 12 in the projection direction of the display screen 30 at least partially overlap. The circuit board 10 is connected to the first feed terminal 11 and the second feed terminal 21 respectively. The circuit board 10 is used to differentially feed the first radiator 1 and the second radiator 2 to excite the first radiator 1 and the second radiator 2 to generate resonance in a first frequency band.

[0066] In this embodiment, the first radiator 1 and the second radiator 2 can overlap along the first direction X. Since the first radiator 1 and the second radiator 2 are differentially fed, the currents fed into the first feed terminal 11 and the second feed terminal 21 at the same time are opposite. Furthermore, since the first feed terminal 11 and the second feed terminal 21 are structurally located on different sides of the first radiator 1 and the second radiator 2, the currents in the first radiator 1 and the second radiator 2 are equal in magnitude and have the same direction. Compared to a radiator extending a first length along the second direction Y, the communication performance provided by the first radiator 1 and the second radiator 2 is improved when the lengths of the first radiator 1 and the second radiator 2 extending along the second direction Y remain unchanged.

[0067] The first radiator 1 and the second radiator 2 can be used together to realize NFC communication. By stacking the first radiator 1 and the second radiator 2 and setting the feed terminal and ground terminal in opposite directions, the performance of the first radiator 1 and the second radiator 2 is doubled compared with the NFC radiator of the same length, the length of the conductive frame 20 occupied by the NFC radiator is reduced, and the space utilization is improved.

[0068] In some embodiments, the conductive frame 20 further includes:

[0069] The fourth radiator 4 is arranged at intervals along the second direction Y with the first radiator 1 and the second radiator 2 respectively. The fourth radiator 4 includes a fourth feed terminal 41 connected to the circuit board 10. The circuit board 10 is used to excite the fourth radiator 4 to generate resonance in the fourth frequency band. The first frequency band and the fourth frequency band are different.

[0070] When the first radiator 1 and the second radiator 2 are used together to achieve NFC communication, the fourth radiator 4 can be used to achieve non-NFC communication, such as cellular communication or WIFI communication. That is, other radiators for achieving non-first frequency band resonance can also be set on the conductive frame 20.

[0071] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
