[0026] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0027] The features of the terms "first" and "second" in the specification and claims of this application may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, the meaning of "plurality" is two or more.

[0028] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] Combine the following Figure 1-Figure 11 The electronic device and the control method according to the embodiments of the present application are described in detail.

[0030] like Figure 1 and Figure 3 As shown, an embodiment of the present application provides an electronic device 100. The electronic device 100 includes a camera decorative ring 104, and the camera decorative ring 104 is designed in the form of a winding coil.

[0031] Furthermore, the electronic device 100 also includes an NFC coil 102 and a switching circuit 106 .

[0032] The NFC coil 102 and the camera decoration ring 104 are concentric and spaced apart.

[0033] Furthermore, the NFC coil 102 is used to receive NFC signals.

[0034] Furthermore, the switching circuit 106 is connected to at least the camera decorative ring 104 .

[0035] During the operation of the electronic device 100, the camera decorative ring 104 is in a grounded state by default. When the electronic device 100 is in a near field communication mode, that is, in a scenario where the electronic device 100 needs to use the NFC function, the switching circuit 106 is in a first state. At this time, the switching circuit 106 reuses the camera decorative ring 104 as an NFC coil, so that the camera decorative ring 104 is used as an enhanced part of the NFC coil 102, so that the camera decorative ring 104 and the NFC coil 102 receive the NFC signal together, thereby enhancing the reception strength of the NFC signal by the electronic device 100, avoiding the camera decorative ring 104 from affecting the reception signal of the NFC coil 102, and ensuring the success rate of the electronic device using the NFC function. When the electronic device 100 is not in a near field communication mode, that is, in a scenario where the electronic device 100 does not need to use the NFC function, the switching circuit 106 is in a second state. At this time, the switching circuit 106 controls the camera decorative ring 104 to remain grounded.

[0036] It is understandable that if Figure 5As shown in the figure, if the NFC coil of the electronic device is arranged inside the camera decorative ring, when the electronic device is swiping the NFC card against the gate coil, the field strength received by the NFC coil is relatively small. In the related art, in order to ensure the NFC card swiping area, the threshold for waking up NFC and the threshold for controlling NFC to start communication are set too low, which will worsen the crash problem when swiping the NFC card.

[0037] Therefore, in the electronic device 100 of the embodiment of the present application, the camera decorative ring 104 is designed to be a winding coil, so that the camera decorative ring 104 can be used as an enhanced part of the NFC coil 102, and a switching circuit 106 is added, and then according to the usage scenario of the electronic device 100, when the electronic device 100 uses the NFC function, the camera decorative ring 104 is multiplexed as an NFC coil through the switching circuit 106, so that the camera decorative ring 104 and the NFC coil receive the NFC signal together, thereby increasing the reception strength of the NFC signal by the electronic device 100, and when the electronic device 100 does not use the NFC function, the camera decorative ring 104 is kept grounded through the switching circuit 106.

[0038] In actual application, the camera decoration ring 104 can also be reused as a relay coil, and the relay coil can be used to increase the NFC area, thereby improving the success rate of NFC card swiping.

[0039] According to the electronic device 100 of the embodiment of the present application, it includes a camera decorative ring 104, an NFC coil 102 and a switching circuit 106. Among them, the NFC coil 102 and the camera decorative ring 104 are concentric and spaced apart, and the switching circuit 106 is at least connected to the camera decorative ring 104. Further, when the switching circuit 106 is in a first state, the camera decorative ring 104 and the NFC coil 102 receive the NFC signal together; when the switching circuit 106 is in a second state, the camera decorative ring 104 is grounded through the switching circuit 106. Through the above electronic device 100, the camera decorative ring 104 is designed as a winding coil, and the switching circuit 106 is added, and then by adjusting the working state of the switching circuit 106, the camera decorative ring 104 and the NFC coil 102 are controlled to receive the NFC signal together, or the camera decorative ring 104 is controlled to be grounded. In this way, the camera decorative ring 104 is designed as a winding coil, so that the camera decorative ring 104 can be used as an enhanced part of the NFC coil 102, which is convenient for dynamically adjusting the grounding state of the camera decorative ring 104 according to the usage scenario of the electronic device 100, so as to keep the camera decorative ring 104 grounded when the electronic device 100 is not using the NFC function, and when the electronic device 100 is using the NFC function, the camera decorative ring 104 is multiplexed as an NFC coil to increase the reception strength of the electronic device 100 to the NFC signal, thereby improving the success rate of using the NFC function of the electronic device 100.

[0040] According to some embodiments of the present application, optionally, Figure 1 As shown, the switching circuit 106 can be connected between the NFC coil 102 and the camera decorative ring 104. Figure 2 As shown, the switching circuit 106 includes a first switch 108 , a second switch 110 , a third switch 112 , a fourth switch 114 , and a fifth switch 116 .

[0041] The first switch 108 is a single-pole single-throw switch. A first end of the first switch 108 is connected to a first end of the NFC coil 102 , and a second end of the first switch 108 is connected to a second end of the NFC coil 102 .

[0042] Further, the second switch 110 is a single-pole single-throw switch. A first end of the second switch 110 is connected to a first end of the first switch 108 , and a second end of the second switch 110 is connected to the fifth switch 116 .

[0044] Further, the fourth switch 114 is a single-pole double-throw switch. A first end D1 of the fourth switch 114 is grounded, a second end D2 of the fourth switch 114 is connected to the second end of the third switch 112 , and a third end D of the fourth switch 114 is connected to the second end of the camera decorative ring 104 .

[0045] Further, the fifth switch 116 is a single-pole double-throw switch. A first end E1 of the fifth switch 116 is grounded, a second end E2 of the fifth switch 116 is connected to the second end of the second switch 110 , and a third end E of the fifth switch 116 is connected to the first end of the camera decorative ring 104 .

[0046] During the operation of the electronic device 100, the camera decorative ring 104 is in a grounded state by default. When the electronic device 100 is in a near field communication mode, that is, when the electronic device 100 needs to use the NFC function, the connection state of the first switch 108, the second switch 110, the third switch 112, the fourth switch 114, and the fifth switch 116 is controlled to disconnect the camera decorative ring 104 from the ground, and connect the first end of the NFC coil 102 to the first end of the camera decorative ring 104, and connect the second end of the NFC coil 102 to the second end of the camera decorative ring 104, so as to conduct the NFC coil 102 and the camera decorative ring 104, thereby increasing the area of ​​the NFC coil and improving the success rate of the electronic device using the NFC function. When the electronic device 100 is not in the near field communication mode, that is, when the electronic device 100 does not need to use the NFC function, the connection state of the first switch 108, the second switch 110, the third switch 112, the fourth switch 114 and the fifth switch 116 is controlled to disconnect the connection between the camera decorative ring 104 and the NFC coil 102, and control the camera decorative ring 104 to be grounded. In this way, by adding a switching circuit 106 between the camera decorative ring 104 and the NFC coil 102, and using the switch in the switching circuit 106 to control the camera decorative ring 104 to be connected to the NFC coil 102, or to control the camera decorative ring 104 to be grounded, the area of ​​the NFC coil can be increased when the electronic device 100 uses the NFC function, thereby increasing the reception strength of the electronic device 100 to the NFC signal, and improving the success rate of the electronic device 100 using the NFC function.

[0047] According to the electronic device 100 of the embodiment of the present application, the switching circuit 106 includes a first switch 108, a second switch 110, a third switch 112, a fourth switch 114 and a fifth switch 116. Among them, the first end of the first switch 108 is connected to the first end of the NFC coil 102, and the second end of the first switch 108 is connected to the second end of the NFC coil 102; the first end of the second switch 110 is connected to the first end of the first switch 108; the first end of the third switch 112 is connected to the second end of the first switch 108; the first end of the fourth switch 114 is grounded, the second end of the fourth switch 114 is connected to the second end of the third switch 112, and the third end of the fourth switch 114 is connected to the second end of the camera decorative ring 104; the first end of the fifth switch 116 is grounded, the second end of the fifth switch 116 is connected to the second end of the second switch 110, and the third end of the fifth switch 116 is connected to the first end of the camera decorative ring 104. In this way, a switching circuit 106 is added between the camera decorative ring 104 and the NFC coil 102, and the switch in the switching circuit 106 is used to control the connection between the camera decorative ring 104 and the NFC coil 102, or to control the camera decorative ring 104 to be grounded. When the electronic device 100 uses the NFC function, the area of ​​the NFC coil can be increased, thereby increasing the receiving strength of the electronic device 100 for the NFC signal and improving the success rate of the electronic device 100 using the NFC function.

[0048] According to some embodiments of the present application, optionally, when the switching circuit 106 is connected between the NFC coil 102 and the camera decorative ring 104, when the electronic device 100 is not in the near field communication mode, that is, when the electronic device 100 does not need to use the NFC function, the switching circuit 106 is in the second state and the electronic device 100 is in the default state.

[0049] When the switching circuit 106 is in the second state, the first switch 108 is closed, the second switch 110 and the third switch 112 are opened, the third end D of the fourth switch 114 is connected to the first end D1 of the fourth switch 114, and the third end E of the fifth switch 116 is connected to the first end E1 of the fifth switch 116. At this time, the camera decorative ring 104 is grounded through the switching circuit 106, and the NFC coil 102 is connected alone.

[0050] Furthermore, when the electronic device 100 is in the near field communication mode, that is, when the electronic device 100 needs to use the NFC function, the switching circuit 106 is in the first state, and the electronic device 100 is in the NFC enhanced state.

[0051] When the switching circuit 106 is in the first state, the first switch 108 is opened, the second switch 110 and the third switch 112 are closed, the third end D of the fourth switch 114 is connected to the second end D2 of the fourth switch 114, and the third end E of the fifth switch 116 is connected to the second end E2 of the fifth switch 116. At this time, the camera decorative ring 104 is disconnected from the ground, and the camera decorative ring 104 is connected to the NFC coil 102 through the switching circuit 106, and the camera decorative ring 104 and the NFC coil 102 receive the NFC signal together.

[0052] In actual application, based on the different NFC states of the electronic device 100 , the switching logic of each switch in the switching circuit 106 may be specifically as shown in Table 1 below.

[0053] Table 1: NFC status and switch logic table

[0054] NFC status First switch Second switch Third switch Fourth switch Fifth switch Default state closure disconnect disconnect D connects to D1 E connects to E1 Enhanced status disconnect closure closure D connects to D2 E connects to E2

[0055] For example, Figure 6 As shown, when the electronic device 100 provided by the embodiment of the present application performs NFC card swiping, the working process of the electronic device 100 may specifically include the following S302 to S314:

[0056] S302: The NFC status is the default status.

[0057] S304: Determine: There is an NFC signal input, if yes, execute S306, if not, execute S302.

[0058] S306: The first switch is turned off.

[0059] S308: The second switch and the third switch are closed.

[0060] S310: The fourth switch: D is connected to D2, and the fifth switch: E is connected to E2.

[0061] S312: The NFC state changes to the enhanced state.

[0062] S314: Determine: NFC card swiping is successful, if so, end the process, if not, execute S306.

[0063] According to the electronic device 100 of the embodiment of the present application, when the switching circuit 106 is in the second state, the first switch 108 is closed, the second switch 110 and the third switch 112 are opened, the third end of the fourth switch 114 is connected to the first end of the fourth switch 114, the third end of the fifth switch 116 is connected to the first end of the fifth switch 116, and the camera decorative ring 104 is grounded through the switching circuit 106; when the switching circuit 106 is in the first state, the first switch 108 is opened, the second switch 110 and the third switch 112 are closed, the third end of the fourth switch 114 is connected to the second end of the fourth switch 114, and the third end of the fifth switch 116 is connected to the second end of the fifth switch 116, so as to turn on the NFC coil 102 and the camera decorative ring 104, and the camera decorative ring 104 and the NFC coil jointly receive the NFC signal. In this way, by using the switch in the switching circuit 106 to control the connection between the camera decorative ring 104 and the NFC coil 102, or to control the camera decorative ring 104 to be grounded, the area of ​​the NFC coil can be increased when the electronic device 100 uses the NFC function, thereby increasing the reception strength of the electronic device 100 to the NFC signal, and improving the success rate of the electronic device 100 using the NFC function.

[0064] According to some embodiments of the present application, optionally, Figure 2 As shown, the switching circuit 106 further includes a first capacitor 118 and a second capacitor 120 .

[0065] The first end of the first capacitor 118 is connected to the first end of the first switch 108 , and the second end of the first capacitor 118 is connected to the first end of the second switch 110 .

[0066] Further, a first end of the second capacitor 120 is connected to a second end of the first switch 108 , and a second end of the second capacitor 120 is connected to a first end of the third switch 112 .

[0067] During the operation of the electronic device 100 , the first capacitor 118 and the second capacitor 120 are used as resonant capacitors to adjust the resonant frequency of the NFC coil 102 and the camera decorative ring 104 after they are turned on, so that the camera decorative ring 104 is used as an enhanced part of the NFC coil 102 .

[0068] The capacitance values ​​of the first capacitor 118 and the second capacitor 120 satisfy that the resonant frequency of the NFC coil 102 and the camera decorative ring 104 after being turned on is consistent with the resonant frequency of the single NFC coil 102. Thus, compared with the single NFC coil 102, the NFC coil 102 and the camera decorative ring 104 after being turned on can be used as a NFC coil with a larger area, so that the camera decorative ring 104 can be reused as an NFC coil, the area of ​​the NFC coil is increased, and the success rate of the electronic device 100 using the NFC function is improved.

[0069] Furthermore, the capacitance values ​​of the first capacitor 118 and the second capacitor 120 are fixed values. In actual application, the specific capacitance values ​​of the first capacitor 118 and the second capacitor 120 can be selected according to actual conditions and are not specifically limited here.

[0070] According to the electronic device 100 of the embodiment of the present application, the switching circuit 106 further includes a first capacitor 118 and a second capacitor 120. The first end of the first capacitor 118 is connected to the first end of the first switch 108, and the second end of the first capacitor 118 is connected to the first end of the second switch 110. The first end of the second capacitor 120 is connected to the second end of the first switch 108, and the second end of the second capacitor 120 is connected to the first end of the third switch 112; wherein, the capacitance values ​​of the first capacitor 118 and the second capacitor 120 satisfy: the resonant frequency of the NFC coil 102 and the camera decorative ring 104 after being turned on is consistent with the resonant frequency of the single NFC coil 102. In this way, by adjusting the resonant frequency of the NFC coil 102 and the camera decorative ring 104 after being turned on by the first capacitor 118 and the second capacitor 120, the camera decorative ring 104 can be reused as the NFC coil, so that the camera decorative ring 104 is used as the enhanced part of the NFC coil 102, the area of ​​the NFC coil is increased, and the success rate of the electronic device 100 using the NFC function is improved.

[0071] According to some embodiments of the present application, optionally, Figure 3 As shown, the switching circuit 106 can be connected only to the camera decorative ring 104. Figure 4 As shown, the switching circuit 106 includes a rectifier circuit 124 , a sixth switch 126 , and a seventh switch 128 .

[0072] The first end of the rectifier circuit 124 is connected to the sixth switch 126 , and the second end of the rectifier circuit 124 is connected to the seventh switch 128 .

[0073] Further, the sixth switch 126 is a single-pole double-throw switch. A first terminal F1 of the sixth switch 126 is grounded, a second terminal F2 of the sixth switch 126 is connected to a first terminal of the rectifier circuit 124 , and a third terminal F of the sixth switch 126 is connected to a second terminal of the camera decorative ring 104 .

[0074] Further, the seventh switch 128 is a single-pole double-throw switch. A first end G1 of the seventh switch 128 is grounded, a second end G2 of the seventh switch 128 is connected to the second end of the rectifier circuit 124 , and a third end G of the seventh switch 128 is connected to the first end of the camera decorative ring 104 .

[0075] Furthermore, the rectifier circuit 124 is used to adjust the resonant frequency of the camera decorative ring 104. When the rectifier circuit 124 and the camera decorative ring 104 are turned on, the rectifier circuit 124 can adjust the resonant frequency of the camera decorative ring 104 to reuse the camera decorative ring 104 as an NFC coil, thereby increasing the number of NFC coils and allowing two NFC coils to work simultaneously. At this time, the two NFC coils simultaneously sense the NFC signal, which enhances the reception strength of the electronic device 100 for the NFC signal. The electronic device 100 can use the NFC signal with the best signal quality received by the two NFC coils, thereby improving the success rate of the electronic device 100 using the NFC function.

[0076] Specifically, during the operation of the electronic device 100, the camera decorative ring 104 is in a grounded state by default. When the electronic device 100 is in a near field communication mode, that is, when the electronic device 100 needs to use the NFC function, the connection state of the sixth switch 126 and the seventh switch 128 is controlled to disconnect the connection between the camera decorative ring 104 and the ground, and the camera decorative ring 104 and the rectifier circuit 124 are turned on to adjust the resonant frequency of the camera decorative ring 104 through the rectifier circuit 124, so that the camera decorative ring 104 is reused as an NFC coil. When the electronic device 100 is not in a near field communication mode, that is, when the electronic device 100 does not need to use the NFC function, the connection state of the sixth switch 126 and the seventh switch 128 is controlled to disconnect the connection between the camera decorative ring 104 and the rectifier circuit 124, and the camera decorative ring 104 is controlled to be grounded. In this way, a switching circuit 106 is set on the camera decorative ring 104, and the switch and the rectifier circuit 124 in the switching circuit 106 are used to control the resonant frequency of the camera decorative ring 104. When the electronic device 100 uses the NFC function, the camera decorative ring 104 can be reused as an NFC coil, thereby increasing the number of NFC coils, increasing the receiving strength of the electronic device 100 for the NFC signal, and improving the success rate of the electronic device 100 using the NFC function.

[0077] According to the electronic device 100 of the embodiment of the present application, the switching circuit 106 includes a rectifier circuit 124, a sixth switch 126 and a seventh switch 128. The rectifier circuit 124 is used to adjust the resonant frequency of the camera decorative ring 104; the first end of the sixth switch 126 is grounded, the second end of the sixth switch 126 is connected to the first end of the rectifier circuit 124, and the third end of the sixth switch 126 is connected to the second end of the camera decorative ring 104; the first end of the seventh switch 128 is grounded, the second end of the seventh switch 128 is connected to the second end of the rectifier circuit 124, and the third end of the seventh switch 128 is connected to the first end of the camera decorative ring 104.

In this way, the resonant frequency of the camera decorative ring 104 is controlled by using the switch and the rectifier circuit 124 in the switching circuit 106, so that when the electronic device 100 uses the NFC function, the camera decorative ring 104 can be reused as an NFC coil, thereby increasing the number of NFC coils, increasing the reception strength of the electronic device 100 to the NFC signal, and improving the success rate of the electronic device 100 using the NFC function.
