[0003] In order to improve the texture and aesthetics of electronic devices, some electronic devices use a metal decorative part 01 in the rear camera area, and the camera module 02 is arranged in the metal decorative part 01.

[0004] However, the metal decorative parts occupy a larger area on the back of the electronic device, so that the distance between the metal decorative parts and the edge of the electronic device is small, so that the layout space of the NFC antenna is severely compressed, and the layout area of ​​NFC is insufficient, resulting in a sharp decline in NFC communication performance, seriously affecting the user experience. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide an NFC component and an electronic device, which can at least solve the problem that the current NFC layout space on the electronic device is insufficient and affects the communication performance.

[0013] In the embodiment of the present application, an NFC line is arranged inside the ring, and the other end of the NFC line is connected to the ring, and at least part of the NFC line is arranged close to the inner wall of the ring, so that the current fed into the ring through the feeding end can be transmitted to the NFC line through the ring, and grounded through the NFC line. At the same time, when the current flows in the ring and the NFC line, the magnetic field in the ring is superimposed, so that the performance of the NFC component is improved. In addition, when the NFC component is applied to an electronic device, the decorative part of the electronic device can be used as the ring of the NFC component, so that the existing structure can be applied to meet the function of the NFC component, and the NFC line is arranged inside the decorative part, so that there is no need to provide additional installation space for the NFC line, and thus there will be no problem of affecting its performance due to the compression of the installation space of the NFC line, so that the NFC component maintains a better function.

[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0030] The embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0031] refer to Figures 3 to 8 The embodiment of the present application discloses an NFC component 10, which can be applied to electronic devices, such as mobile phones, tablet computers, wearable devices, etc. Of course, it can also be applied to other devices, which are not specifically limited here. The disclosed NFC component 10 includes a ring 11 and an NFC trace 12.

[0032] The ring 11 is a basic component, which can provide an installation basis for the NFC wiring 12. In some embodiments, the NFC wiring 12 is arranged in the space surrounded by the ring 11, and the other end of the NFC wiring 12 is connected to the ring 11, so that the ring 11 can provide a space for the NFC wiring 12 to accommodate, so as to avoid the situation that the NFC wiring 12 cannot be provided with a large enough installation space due to the cramped external space of the ring 11, resulting in insufficient wiring area of ​​the NFC wiring 12 and ultimately affecting the communication performance of the NFC component 10, and the ring 11 can also play a certain protective role and shielding role to the NFC wiring 12 to a certain extent, so as to prevent external factors from causing the NFC wiring 12 to be damaged and affect the communication performance, and can also avoid the NFC wiring 12 from being exposed and affecting the appearance performance of the electronic device. In addition, it is also possible to avoid occupying other layout spaces to ensure that other components have enough installation space. Optionally, the NFC wiring 12 can be partially arranged in the space surrounded by the ring 11, and the other part is arranged outside the space. Of course, the NFC wiring 12 can also be arranged entirely in the space surrounded by the ring 11.

[0033] In addition to the above functions, the ring 11 can also play a role in diverting current so that the current can be transferred to the NFC line 12 to achieve the communication function. In order to achieve the feeding of current, the ring 11 can be provided with a feeding end 111, and the feeding end 111 can be connected to the circuit board of the electronic device so as to feed the current to the ring 11 through the feeding end 111. It should be noted here that the separate feeding causes the ring 11 to have less mutual influence with the main antenna of the electronic device, so there is no need to introduce additional large inductance for high-frequency isolation.

[0034] Exemplarily, the shape of the ring 11 may include a circle, an ellipse and a polygon, wherein the polygon may be a rectangle, a square, a triangle, a hexagon, etc. Of course, it may also be other shapes, which are not specifically limited here.

[0035] In addition, to realize the function of the NFC component 10, one end of the NFC line 12 is set as a ground terminal 121, so that the NFC line 12 is grounded through the ground terminal 121. Optionally, the ground terminal 121 is located outside the space surrounded by the ring 11; optionally, the ground terminal 121 is located inside the space surrounded by the ring 11. Exemplarily, the NFC line 12 can be connected to the device body of the electronic device, and the device body can have conductive properties, such as being made of metal material, so that the current output by the NFC line 12 is transmitted to the device body.

[0036] In some embodiments, the feeding end 111 and the connection point between the NFC line 12 and the ring 11 (i.e., the confluence 112 described below) can separate the ring 11 into two parts, and the current fed through the feeding end 111 can be divided into two sub-currents at the feeding end 111, and the two sub-currents flow along the two parts of the ring 11 respectively, and finally converge at the connection point, and then flow into the NFC line 12 through the connection point, and then output through the ground terminal 121 of the NFC line 12. In this way, in the process of current flowing through the ring 11 and the NFC line 12, a magnetic field working area can be generated in the ring 11, so as to realize signal transmission through the interaction between the magnetic field working area and other communication devices. It should be noted here that the working principle of the NFC component 10 and the signal transmission principle between other communication devices can refer to the prior art and will not be elaborated here.

[0037] In some embodiments, the NFC component 10 can use the feeding terminal 111 to implement a single-ended feeding method. In addition, the ground terminal 121 can also be changed to a differential feeding method to implement a dual-end NFC solution. It should be noted here that the feeding method of the NFC component 10 can refer to the relevant technology and will not be elaborated here.

[0038] Figure 2 A grounding scheme for NFC is disclosed, wherein the decorative piece is rectangular in shape, and the decorative piece is fed at the end of one short side of the rectangular decorative piece, and the other short side of the rectangular decorative piece is grounded, so that during the feeding process, the current flows from the feeding point to the grounding point through two paths, that is, the currents are I1 and I2, respectively, and flow in the same direction, and finally converge at the grounding point to form a current I3. Since the currents of the two paths are in the same direction, the positive and negative magnetic fields generated inside the ring 11 are offset to zero, which will cause a large working blind area at the center, and ultimately lead to poor communication performance of NFC.

[0039] To solve the above problem, in an embodiment of the present application, the NFC wiring 12 is arranged in the ring 11, and at least a portion of the NFC wiring 12 is arranged close to the inner wall of the ring 11. In this way, the currents in the above two paths can be adjusted so that the magnetic fields in the ring 11 are superimposed on each other instead of canceling each other out, thereby effectively avoiding the situation where the magnetic fields inside the ring 11 cancel each other out to zero, thereby ensuring the communication performance of the NFC component 10.

[0040] It should be noted here that the current input into the ring member 11 via the feeding terminal 111 flows to the connection point between the NFC wiring 12 and the ring member 11 via two parts of the path, wherein the currents in the two parts of the path are I1 and I2 respectively, and then the currents merge and flow into the NFC wiring 12 to form the I3 current. Since at least part of the NFC wiring 12 is close to the inner wall of the ring member 11, the flow directions of I1 and I3 are the same, and the flow directions of I2 and I3 are opposite. In this way, the magnetic field between I1 and I3 can be strengthened and no longer offset each other, which is beneficial to improving the communication performance of the NFC component 10; of course, it can also be that the flow directions of I2 and I3 are the same, and the flow directions of I1 and I3 are opposite. In this way, the magnetic field between I2 and I3 can be strengthened and no longer offset each other, which is also beneficial to improving the communication performance of the NFC component 10.

[0041] Based on the above configuration, in the embodiment of the present application, an NFC wiring 12 is arranged inside the ring 11, and the other end of the NFC wiring 12 is connected to the ring 11, and at least a portion of the NFC wiring 12 is arranged close to the inner wall of the ring 11. In this way, the current fed into the ring 11 via the feeding end 111 can be transmitted to the NFC wiring 12 via the ring 11 and grounded through the NFC wiring 12. At the same time, when the current flows in the ring 11 and the NFC wiring 12, the magnetic field in the ring 11 will be superimposed, thereby improving the performance of the NFC component 10.

[0042] In addition, when the NFC component 10 is applied to an electronic device, the decorative part of the electronic device can be used as the ring part 11 of the NFC component 10, so that the existing structure can be applied to meet the function of the NFC component 10, and the NFC wiring 12 is arranged inside the decorative part, so that there is no need to provide additional installation space for the NFC wiring 12, and the problem of affecting the performance of the NFC wiring 12 due to the compression of the installation space will not occur, so that the NFC component 10 maintains better function.

[0043] In some embodiments, the ring 11 may also be provided with a confluence portion 112, which is both a connection point between the NFC trace 12 and the ring 11 and a current convergence point in each current path of the ring 11. In the circumferential direction of the ring 11, the confluence portion 112 is spaced apart from the feeding end 111, so that the ring 11 can form two different current paths between the feeding end 111 and the confluence portion 112.

[0044] In addition, in the circumferential direction of the annular member 11 , the merging portion 112 and the grounding end 121 are spaced apart from each other, so that the merging portion 112 and the grounding end 121 can be connected via the NFC wiring 12 to achieve signal transmission.

[0045] In the embodiment of the present application, the other end of the NFC trace 12 is connected to the confluence portion 112, so that the current in each current path of the ring member 11 can flow into the NFC trace 12 through the confluence portion 112, and finally be output through the grounding terminal 121 provided at one end of the NFC trace 12 to achieve grounding.

[0046] Considering that the NFC line 12 is disposed in the ring 11 , in some embodiments, the other end of the NFC line 12 can be connected to the inner wall of the ring 11 and located at the confluence portion 112 to meet the setting requirements of the NFC line 12 and the ring 11 .

[0047] In addition, at least a portion of the NFC line 12 between the confluence portion 112 and the grounding end 121 extends in an area close to the inner wall of the ring 11. The entire area of ​​the NFC line 12 between the confluence portion 112 and the grounding end 121 may extend close to the inner wall of the ring 11, or a section of the NFC line 12 between the confluence portion 112 and the grounding end 121 may extend close to the inner wall of the ring 11. The specific setting can be based on actual working conditions and is not specifically limited here.

[0048] The first embodiment: the confluence portion 112 and the grounding end 121 are located on the same center line MN of the ring member 11, and the confluence portion 112 and the grounding end 121 are arranged opposite to each other. Optionally, when the shape of the ring member 11 is circular, the confluence portion 112 and the grounding end 121 can be located at the two ends of the same diameter of the circle; when the shape of the ring member 11 is rectangular, the confluence portion 112 and the grounding end 121 can be located at the midpoints of the two short sides of the rectangle; when the shape of the ring member 11 is elliptical, the confluence portion 112 and the grounding end 121 can be located at the two end points of the long axis of the ellipse.

[0049] Furthermore, the NFC line 12 extends in an area close to the inner wall and on one side of the center line MN of the ring 11, that is, the entire area of ​​the NFC line 12 is located on one side of the same center line MN where the confluence portion 112 and the ground terminal 121 are located, and extends in an area close to the inner wall. Based on this arrangement, the magnetic field between the current in the NFC line 12 and the current in the path of the ring 11 located on the other side of the center line MN can be strengthened, thereby improving the communication performance of the NFC component 10.

[0050] Taking the rectangular ring member 11 as an example, Figure 4As shown, part of the current fed through the feeding end 111 flows into one of the paths of the ring 11, namely I1, and the other part of the current flows into another path of the ring 11, namely I2. The currents in the two paths converge at the confluence 112 and flow into the NFC line 12, namely I3. Since the NFC line 12 extends in an area close to another path and away from one path, the currents of I1 and I3 in the loop are in the same direction, thereby strengthening the magnetic field between I1 and I3 to improve the communication performance of the NFC component 10. In addition, it should be noted that the circuit of I2 still exists, and the currents of I2 and I3 in the loop are opposite, so that the equivalent current formed can be roughly equivalent to I3-I2=I1. At this time, the equivalent current in the entire ring 11 is approximately the complete circulation path of I1, and the magnetic field in the center of the circulation path is superimposed and enhanced. In addition, the current I3 of the NFC line 12 (equivalent to the converging path) is closer to the current I2 in the other path, so that there is a strong coupling between the two paths. When the paths of the two paths are the same, the current proportion of I2 will be significantly greater than that of I1.

[0051] Based on the above content, it can be known that the first embodiment can form a complete unidirectional current (i.e., I1+I3) on the loop of the ring member 11, so that the magnetic field inside the ring member 11 can be superimposed. Therefore, the current loop constructed by the new current path introduced by the arrangement of the above-mentioned NFC wiring 12 can effectively improve the communication performance of the NFC component 10.

[0052] Second embodiment: the confluence portion 112 is located on one side of the center line MN of the ring member 11, and the grounding end 121 is located on the center line MN. Optionally, when the shape of the ring member 11 is circular, the grounding end 121 can be located at one end of a diameter of the circle, and the circular ring member 11 can be divided into two side parts by the diameter, and the confluence portion 112 is located in the area of ​​one side part of the ring member 11; when the shape of the ring member 11 is rectangular, the grounding end 121 can be located at the midpoint of a short side of the rectangle, and the confluence portion 112 is located on one of the long sides; when the shape of the ring member 11 is elliptical, the grounding end 121 can be located at one end point of the long axis of the ellipse, and the confluence portion 112 is located between the other end point of the long axis and the end point of one of the short axes.

[0053] Taking into account that the NFC routing 12 extends in an area close to the inner wall of the ring 11, and one end of the NFC routing 12 is connected to the ground terminal 121 located on the center line MN, and the other end of the NFC routing 12 is connected to the confluence portion 112 located on one side of the center line MN, it can be seen that the NFC routing 12 extends from the confluence portion 112 to the ground terminal 121, and can extend from one side of the center line MN where the ground terminal 121 is located to the other side.

[0054] Based on the above configuration, in the embodiment of the present application, the NFC line 12 may include a first line segment 1221 and a second line segment 1222 connected to each other, wherein the first line segment 1221 extends from the confluence portion 112 to the center line MN where the ground terminal 121 is located in the area close to the inner wall, that is, the first line segment 1221 is the portion between the confluence portion 112 and the center line MN; the second line segment 1222 extends from the center line MN to the ground terminal 121 in the area close to the inner wall, that is, the second line segment 1222 is the portion between the center line MN and the ground terminal 121. Based on this configuration, the magnetic field between the current in the NFC line 12 and the current in the path of the ring 11 between the confluence portion 112 and the center line MN can be strengthened, thereby improving the communication performance of the NFC component 10.

[0055] Taking the rectangular ring member 11 as an example, Figure 5 As shown, part of the current fed through the feeding end 111 flows into one of the paths of the ring member 11, namely I1, and the other part of the current flows into another path of the ring member 11, namely I2. The currents in the two paths converge at the confluence portion 112 and flow into the NFC trace 12, namely I3.

[0056] Compared with the first embodiment described above, this embodiment is based on the first embodiment, and changes the setting position of the confluence portion 112, so as to extend the path of the NFC line 12 (i.e., the confluence path), thereby increasing the ratio of the path lengths of I1 and I2, that is, shortening the path length of I1 and extending the path length of I2. Based on this, since the distance between the feeding end 111 and the confluence portion 112 is shorter, that is, the path length of I1 is shorter, the current fed from the feeding end 111 will increase significantly according to the shortest path principle, and at the same time, I2=I3-I1 will decrease accordingly, so that the equivalent working current in the loop path is further strengthened, that is, the proportion of I1 increases, so that a larger magnetic field can be superimposed.

[0057] Based on the above content, it can be known that the second embodiment can form a complete unidirectional current (i.e., I1+I3) on the loop of the ring member 11, so that the magnetic field within the ring member 11 can be further superimposed. Therefore, the current loop constructed by the new current path introduced by the arrangement of the above-mentioned NFC wiring 12 can effectively improve the communication performance of the NFC component 10.

[0058] The third implementation method: Figure 6 and Figure 8As shown, on the basis of the second embodiment, the path of the NFC trace 12 is further extended, that is, on the basis of the second embodiment, the confluence portion 112 is brought closer to the feeding end, that is, the path length of I1 is further shortened, while the path length of I2 is extended, so that the current on I1 can be further increased, and therefore, the equivalent working current in the loop path is further enhanced, that is, the proportion of I1 is further increased, so that a larger magnetic field can be superimposed to form.

[0059] Based on the above settings, the embodiment of the present application adjusts the connection point (i.e., the confluence) where the circulating current path enters the annular member 11 to change the weight ratio of different current paths on the annular member 11, which is beneficial to improving the communication performance of the NFC component 10.

[0060] Fourth embodiment: the confluence portion 112 is located on one side of the center line MN of the ring member 11, and the grounding end 121 is located on the center line MN. Optionally, when the shape of the ring member 11 is circular, the grounding end 121 can be located at one end of a diameter of the circle, and the circular ring member 11 can be divided into two side parts by the diameter, and the confluence portion 112 is located in the area of ​​one side part of the ring member 11; when the shape of the ring member 11 is rectangular, the grounding end 121 can be located at the midpoint of a short side of the rectangle, and the confluence portion 112 is located on one of the long sides; when the shape of the ring member 11 is elliptical, the grounding end 121 can be located at one end point of the long axis of the ellipse, and the confluence portion 112 is located between the other end point of the long axis and the end point of one of the short axes.

[0061] Taking into account that the NFC routing 12 extends in an area close to the inner wall of the ring 11, and one end of the NFC routing 12 is connected to the ground terminal 121 located on the center line MN, and the other end of the NFC routing 12 is connected to the confluence 112 located on one side of the center line MN, it can be seen that the NFC routing 12 extends from the confluence 112 to the ground terminal 121, and can also extend from one side of the center line MN where the ground terminal 121 is located to the center line MN, and further extend along the center line MN.

[0062] Based on the above configuration, in the embodiment of the present application, the NFC line 12 may include a first line segment 1221 and a second line segment 1222 connected to each other, wherein the first line segment 1221 extends from the confluence portion 112 to the center line MN where the ground terminal 121 is located in the area close to the inner wall, that is, the first line segment 1221 is the portion between the confluence portion 112 and the center line MN; the second line segment 1222 extends along the center line MN where the ground terminal 121 is located to the ground terminal 121. Based on this configuration, the magnetic field between the current in the NFC line 12 and the current in the path of the ring 11 between the confluence portion 112 and the center line MN can be strengthened, thereby improving the communication performance of the NFC component 10.

[0063] Taking the circular ring member 11 as an example, Figure 3 As described above, part of the current fed through the feeding end 111 flows into one of the paths of the ring member 11, namely I1, and the other part of the current flows into another path of the ring member 11, namely I2. The currents in the two paths converge at the confluence portion 112 and flow into the NFC trace 12, namely I3.

[0064] Compared with the second and third embodiments described above, the second routing segment 1222 of the NFC routing 12 of this embodiment does not extend in the area close to the inner wall of the ring 11, but extends toward the ground terminal 121 along the center line MN where the ground terminal 121 is located. Compared with the second and third embodiments described above, this arrangement reduces the area of ​​the working area formed, but can also form a complete unidirectional current (I1+I3) on the loop of the ring 11, thereby achieving further superposition of the magnetic field in the ring 11, and thus effectively improving the communication performance of the NFC component 10.

[0065] It should be noted here that, in order to ensure user experience when designing an NFC solution, in some cases, it is desirable to set the main working area of ​​the NFC component 10 in certain areas of the electronic device, such as the top center area. To meet this requirement, the NFC trace 12 in the embodiment of the present application adopts the following Figure 7 The configuration shown, i.e., the fourth embodiment described above, can effectively increase the magnetic field strength in the area to improve the communication performance of the NFC component 10.

[0066] However, considering that in actual situations, other components may be arranged inside the ring 11, such as when the ring 11 is a decorative component, a camera module may be arranged inside it, which may cause certain restrictions on the space of the NFC wiring 12. Therefore, the embodiment of the present application can also flexibly adjust the arrangement of the NFC wiring 12, that is, the second and third embodiments described above can be adopted, which can not only improve the communication performance of the NFC component 10, but also meet the requirements of the NFC component 10 for the installation space.

[0067] The present application example has statistically analyzed the current data in the above four implementation modes, as shown in Table 1.

[0068] Table 1

[0069]

[0070] As can be seen from Table 1, when the combined current I3 is constant, the currents in the two paths in the first embodiment are equal; when the new I3 combined circuit is introduced (i.e., after the NFC line 12), the proportions of I1 and I2 change, and as the combined path increases, the equivalent current I1 in the entire loop increases. Therefore, the current data can further illustrate the effectiveness of introducing the NFC line 12 in improving the communication performance of the NFC component 10.

[0071] In some embodiments, on the circumference of the ring 11, the feeding terminal 111 and the grounding terminal 121 can be arranged to overlap. In this case, the axial projections of the feeding terminal 111 and the grounding terminal 121 can be located on the same center line MN of the ring 11. In this way, on the circumference of the ring 11, the path length from the confluence portion 112 to the feeding terminal 111 is the same as the path length from the confluence portion 112 to the grounding terminal 121, so that one of the passages of the ring 11 and the NFC trace 12 can form a closed loop.

[0072] In order to prevent the feeding end 111 from contacting the grounding end 121 and causing a short circuit, the feeding end 111 and the grounding end 121 are spaced apart in the axial direction of the ring member 11 , so that the short circuit can be effectively prevented.

[0073] Of course, in other embodiments, the feeding terminal 111 and the grounding terminal 121 may be staggered in the circumferential direction of the ring 11 . This approach may also meet the design requirements of the NFC component 10 and prevent a short circuit from occurring.

[0074] In some embodiments, the annular member 11 may be provided with a first end face 113 and a second end face 114 that are axially opposite to each other, wherein the first end face 113 is used to connect with the installation body so as to integrally install the NFC component 10 to the installation body.

[0075] Exemplarily, the installation body may be a device housing 20 of an electronic device, and of course, may also be other components, which are not specifically limited herein. In addition, the annular member 11 may include multiple layers of ferrules arranged along the axial direction.

[0076] The grounding terminal 121 of the NFC line 12 is located on the side where the first end surface 113 of the ring 11 is located, so that the grounding terminal 121 is grounded, thereby outputting the current output by the NFC line 12, and finally forming a complete return path to realize the communication function of the NFC component 10. Exemplarily, the grounding terminal 121 can be connected to the installation body, and of course can also be connected to other grounding components to realize the grounding of the NFC component 10.

[0077] The area of ​​the NFC line 12 away from the ground terminal 121 is arranged close to the second end surface 114. Based on this arrangement, the NFC line 12 can be closer to the external environment, which can help improve the communication performance of the NFC component 10 to a certain extent.

[0078] It should be noted here that the above-mentioned area far from the ground terminal 121 can be understood as: one end of the NFC line 12 is the ground terminal 121, and all other parts except the ground terminal 121 can be understood as the area far from the ground terminal 121. For example, the other end of the NFC line 12, the middle part of the NFC line 12, the part between the ground terminal 121 and the middle part of the NFC line 12, and so on.

[0079] In some embodiments, the NFC trace 12 may include a trace segment body 122, a transition segment 123, and the ground terminal 121, wherein the surface of the trace segment body 122 along the axial direction is flush with the second end face 114, and one end of the trace segment body 122 is connected to the inner wall of the ring member 11. Based on this configuration, the surface of the trace segment body 122 and the second end face 114 can be located in the same plane, which is beneficial to improving the appearance performance of the NFC component 10, and can also make the trace segment body 122 closer to the external environment, thereby improving the communication performance of the NFC component 10 without affecting the appearance.

[0080] The transition section 123 is connected between one end of the routing segment body 122 and the ground terminal 121 . Thus, the provision of the transition section 123 can meet the requirement that the NFC routing 12 extends in the axial direction of the annular member 11 .

[0081] Exemplarily, the transition section 123 can extend along the axial direction of the annular member 11. Of course, the extension direction of the transition section 123 can also form an acute angle with the axial direction. As long as the transition connection between the routing segment body 122 and the grounding end 121 can be achieved, the specific form is not limited.

[0082] In some embodiments, the feeding end 111 may be disposed on the outer wall of the ring 11 and located at the second end face 114, so that the current fed into the feeding end 111 can be excited to the second end face 114 of the ring 11 and flow into the NFC trace 12 near the second end face 114, thereby facilitating the shortening of the current path entering the NFC trace 12 and facilitating the improvement of the communication performance of the NFC component 10. Optionally, the feeding end 111 may contact the second end face 114, or the feeding end 111 may be located in the area between the first end face 113 and the second end face 114, and the distance between the feeding end 111 and the second end face 114 is smaller than the distance between the feeding end 111 and the first end face 113, so that the feeding end 111 is closer to the second end face 114, that is, the feeding end 111 is located at the second end face 114.

[0083] In order to further improve the communication performance of the NFC component 10, the NFC component 10 may also include a non-metallic magnetic part, which is respectively arranged corresponding to the annular part 11 and the NFC wiring 12. In this way, the reverse eddy current influence of the metal ground can be reduced by the non-metallic magnetic part, thereby reducing the influence on the NFC component 10, thereby improving the communication performance of the NFC component 10.

[0084] When the NFC component 10 is installed on a device housing 20 made of metal, the non-metallic magnetic component can be located between the annular component 11 and the NFC wiring 12 and the device housing 20 to reduce the influence of reverse eddy current on the device housing 20 made of metal.

[0085] For example, the non-metallic magnetic member may be ferrite, including the following types: BaO·6Fe 2 O 3 、FeO·Fe 2 O 3 (Fe 3 O 4 ) and so on. Of course, other types may also be included and are not specifically limited here.

[0086] Based on the above-mentioned NFC component 10, an embodiment of the present application further discloses an electronic device, and the disclosed electronic device includes a device housing 20 and the above-mentioned NFC component 10, wherein the NFC component 10 is arranged in the device housing 20, and a decorative part is provided on the surface of the device housing 20, and the annular part 11 is the decorative part.

[0087] Optionally, a camera module may be provided on the surface of the device housing 20, and a decorative component may be provided on the outside of the camera module to cover the camera module, thereby improving the aesthetics.

[0088] In the embodiment of the present application, the decorative part is used as a part of the NFC component 10, which can achieve the effect of one thing for multiple uses, thereby reducing the use of parts and components, reducing costs, and reducing the occupied space to provide more installation space for the NFC component 10.

[0089] In summary, the embodiment of the present application introduces a new NFC circulation path, so that a closed current loop can be constructed without adding breaks on the decorative parts to enhance the magnetic field strength, thereby improving the communication performance of the NFC component 10; by adjusting the connection point (i.e., the confluence) where the circulation path accesses the annular part 11 to change the weight ratio of different current paths on the annular part 11, it is beneficial to improve the communication performance of the NFC component 10; by using the decorative parts as part of the NFC component 10, the cost and occupied space can be reduced, and the distance between the NFC component 10 and the external environment can be reduced, thereby improving the communication performance of the NFC component 10.

[0090] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
