[0050] To make the description of this application more detailed and complete, reference can be made to the accompanying drawings and the various embodiments described below. The components in the drawings are not drawn to scale and are provided for illustrative purposes only. Details of many embodiments are described below to provide a comprehensive understanding of this application; however, those skilled in the art should understand that this application can be implemented without one or more practical details, and therefore, these details should not be used to limit this application.

[0051] Please refer to Figures 1 to 3 . Figure 1 This is a schematic perspective view of an electronic device 15 according to one embodiment of this application. Figure 2 for Figure 1 The electronic device 15 shown is a schematic cross-sectional view at the mark of line segment 2-2, while Figure 3 for Figure 1 The diagram shows a schematic top view of the electronic device 15. As shown, the electronic device 15 includes a housing 16, which includes a first housing component 20 and a second housing component 30. The first housing component 20 and the second housing component 30 are coupled together to define an accommodating space 17. The first housing component 20 includes a metal portion 29 made of a metallic material; in other words, the first housing component 20 is at least partially made of a metallic material. The second housing component 30 may be made of a metallic material or a non-metallic material, or may include both metallic and non-metallic materials.

[0052] In the example shown in the figure, electronic device 15 is an earphone charging case. The second housing component 30 corresponds to the base of the earphone charging case and can be used to house components such as batteries and earphones (not shown). The first housing component 20 can be the top cover of the earphone charging case. The first housing component 20 is disposed above the second housing component 30 and can be pivotally connected to the second housing component 30 via a hinge structure 18. However, it should be understood that electronic device 15 can also be other electronic devices with wireless communication capabilities, and is not limited to an earphone charging case.

[0053] like Figures 1 to 3 As shown, the electronic device 15 also includes a wireless communication module 90, which is disposed within the accommodating space 17 of the housing 16; in other words, the wireless communication module 90 is covered from the outside by the housing 16. The wireless communication module 90 is separate from the metal portion 29 of the first housing component 20, meaning the wireless communication module 90 does not contact the metal portion 29. The wireless communication module 90 may include an antenna and a communication chip. The wireless communication module 90 has a built-in antenna, and the metal portion 29 of the first housing component 20 is not used as part of the antenna of the wireless communication module 90. The wireless communication module 90 may be a communication module based on Wi-Fi, Bluetooth, or other wireless communication protocols, capable of transmitting (transmitting, receiving, or transmitting / receiving) electromagnetic waves. The electromagnetic waves transmitted by the wireless communication module 90 may be 2.4 GHz or other suitable frequencies.

[0054] like Figures 1 to 3 As shown, the metal portion 29 of the first housing component 20 includes a first slot structure 21. The first slot structure 21 penetrates the metal portion 29 and includes at least one first groove 211 and at least one second groove 212. The first groove 211 and the second groove 212 extend in opposite directions, and the second groove 212 is symmetrically arranged on both sides of the first groove 211. In this embodiment, the first groove 211 and the second groove 212 intersect at a point and are interconnected to form a cross-shaped groove. In other words, the first groove 211 and the second groove 212 are intersecting, with the first groove 211 extending through the second groove 212, and the two ends of the first groove 211 located on both sides of the second groove 212. The second groove 212 extends through the first groove 211, and the two ends of the second groove 212 are located on both sides of the first groove 211. The first groove 211 can be symmetrically arranged on both sides of the second groove 212.

[0055] like Figures 1 to 3 As shown, a gap is maintained between the metal portion 29 of the first housing component 20 and the second housing component 30 as a second slot structure 31. The second slot structure 31 can extend along the outer edge of the metal portion 29 and the second housing component 30.

[0056] like Figures 1 to 3As shown, the wireless communication module 90 is disposed facing the first trench 211. In some embodiments, the first housing component 20 and the second housing component 30 are stacked on a third direction D3, and the projection area of ​​the wireless communication module 90 on the metal portion 29 along the third direction D3 partially overlaps with the first trench 211.

[0057] With the above configuration, the wireless communication module 90 of this application can maintain good communication quality even when encased in a metal housing 16. Please refer to... Figure 4 and Figure 5 .like Figure 4 As shown, when the casing of an electronic device consists of metal material but has no openings, the radiation pattern of the wireless communication module is compressed due to the presence of the metal material in the casing, forming a directional radiation pattern (two main lobes). Figure 5 The radiation field pattern of the wireless communication module 90 of the electronic device 15 of this application is shown. As described above, the housing 16 of the electronic device 15 of this application includes a metal material and is provided with a first slot structure 21 and a second slot structure 31, so that the radiation field pattern of the wireless communication module 90 is transformed into an omnidirectional (or near-omnidirectional) radiation field pattern, thereby improving the communication quality of the wireless communication module 90.

[0058] It should be noted that the configuration of the wireless communication module 90, the first slot structure 21, and the second slot structure 31 in this application differs from that of common slot antennas. As described above, the wireless communication module 90 has a built-in antenna, and the metal portion 29 of the first housing component 20 is not considered part of the antenna of the wireless communication module 90. More specifically, no feed point, antenna radiator, or grounding structure is configured in the metal portion 29 of the first housing component 20 or the first slot structure 21. Therefore, the wireless communication module 90, the first slot structure 21, and the second slot structure 31 do not constitute a slot antenna and should not be considered equivalent to a slot antenna. The technology of this application focuses on changing the radiation pattern of the existing antenna of the wireless communication module 90 located inside the housing 16 by setting the first slot structure 21 and the second slot structure 31 of appropriate shape at appropriate positions on the housing 16.

[0059] like Figures 1 to 3As shown, in some embodiments, the first groove 211 is substantially disposed along a first direction D1, and the second groove 212 is substantially disposed along a second direction D2, wherein the first direction D1 and the second direction D2 are substantially perpendicular to each other. In some embodiments, the metal portion 29 may have a generally rectangular or elliptical shape in a top view. In some embodiments, the first groove 211 may be substantially disposed along the minor axis of the metal portion 29, and the second groove 212 may be substantially disposed along the major axis of the metal portion 29. In some embodiments, the ends of the first groove 211 and / or the second groove 212 may be connected to the outer edge of the metal portion 29. In some embodiments, the two ends of the first groove 211 are respectively connected to two opposite edges of the metal portion 29 (e.g., the two long sides of the metal portion 29), and the two ends of the second groove 212 are respectively connected to the other two opposite edges of the metal portion 29 (e.g., the two short sides of the metal portion 29), such that the first groove 211 and the second groove 212 divide the metal portion 29 into four separate parts.

[0060] like Figures 1 to 3 As shown, in some embodiments, the first groove 211 and the second groove 212 are disposed in the center of the metal portion 29. In some embodiments, the first groove 211 is disposed along a first plane of symmetry P1 of the metal portion 29, and the second groove 212 is disposed along a second plane of symmetry P2 of the metal portion 29, which is different from the first plane of symmetry P1. The first plane of symmetry P1 is, for example, a plane passing through the minor axis of the metal portion 29, while the second plane of symmetry P2 is, for example, a plane passing through the major axis of the metal portion 29. With the above configuration, the first slot structure 21 can form a symmetrical interference region, which can uniformly change the radiation directionality of the wireless communication module 90 and improve the tolerance of the electronic device 15 to assembly tolerances. When the position of the wireless communication module 90 is deviated, it can still be uniformly interfered by the first slot structure 21, making its radiation pattern more stable. In some embodiments, when the first groove 211 is slightly deviated from the first symmetry plane P1 and / or the second groove 212 is slightly deviated from the second symmetry plane P2 (within 5 mm), it is still possible to uniformly change the radiation directionality of the wireless communication module 90 and improve the stability of the radiation field pattern.

[0061] like Figures 1 to 3As shown, in some embodiments, the width Wl of the first groove 211 and the width W2 of the second groove 212 of the first slot structure 21 fall within the range of 0.85 mm to 2 mm. In some embodiments, the width W3 of the second slot structure 31 is at least 0.2 mm. In some embodiments, the length of the first groove 211 facing the wireless communication module 90 is substantially more than one quarter of the wavelength of the radio waves emitted by the wireless communication module 90, and the length of the second groove 212 is substantially more than one half of the wavelength of the radio waves emitted by the wireless communication module 90. More specifically, when the first groove 211 is arranged substantially along the short axis of the metal portion 29 and intersects with the second groove 212 to form a cross-shaped slot as shown, and when the second groove 212 is arranged substantially along the long axis of the metal portion 29 as shown, the length LI of the first groove 211 is substantially more than one half of the wavelength of the radio waves emitted by the wireless communication module 90, and the length L2 of the second groove 212 is substantially more than 0.7 times the wavelength of the radio waves emitted by the wireless communication module 90. For example, the wavelength of a 2.4 GHz radio wave is 125 mm, and accordingly, the length of the first groove 211 is about 62.5 mm or more, and the length of the second groove 212 is about 87.5 mm or more. The length L2 of the second groove 212 can be greater than the length LI of the first groove 211. When the dimensions of the first slot structure 21 and the second slot structure 31 fall within the above-mentioned numerical ranges, the radiation pattern of the wireless communication module 90 can be effectively changed to be omni-directional (or nearly omni-directional). Conversely, when the dimensions of the first slot structure 21 and the second slot structure 31 fall outside the above-mentioned numerical ranges, the improvement effect on the radiation pattern of the wireless communication module 90 is not obvious. Figure 3 Figure 3 As shown, in some embodiments, the width Wl of the first groove 211 and the width W2 of the second groove 212 of the first slot structure 21 fall within the range of 0.85 mm to 2 mm. In some embodiments, the width W3 of the second slot structure 31 is at least 0.2 mm. In some embodiments, the length of the first groove 211 facing the wireless communication module 90 is substantially more than one quarter of the wavelength of the radio waves emitted by the wireless communication module 90, and the length of the second groove 212 is substantially more than one half of the wavelength of the radio waves emitted by the wireless communication module 90. More specifically, when the first groove 211 is arranged substantially along the short axis of the metal portion 29 and intersects with the second groove 212 to form a cross-shaped slot as shown, and when the second groove 212 is arranged substantially along the long axis of the metal portion 29 as shown, the length LI of the first groove 211 is substantially more than one half of the wavelength of the radio waves emitted by the wireless communication module 90, and the length L2 of the second groove 212 is substantially more than 0.7 times the wavelength of the radio waves emitted by the wireless communication module 90. For example, the wavelength of a 2.4 GHz radio wave is 125 mm, and accordingly, the length of the first groove 211 is about 62.5 mm or more, and the length of the second groove 212 is about 87.5 mm or more. The length L2 of the second groove 212 can be greater than the length LI of the first groove 211. When the dimensions of the first slot structure 21 and the second slot structure 31 fall within the above-mentioned numerical ranges, the radiation pattern of the wireless communication module 90 can be effectively changed to be omni-directional (or nearly omni-directional). Conversely, when the dimensions of the first slot structure 21 and the second slot structure 31 fall outside the above-mentioned numerical ranges, the improvement effect on the radiation pattern of the wireless communication module 90 is not obvious.

[0062] It should be noted that, Figure 3 For the sake of labeling, the width of the first groove 211 in the first direction Dl is labeled as the length LI, and the width of the second groove 212 in the second direction D2 is labeled as the length L2, but it should be understood that the lengths LI, L2 represent the actual lengths of the first groove 211 and the second groove 212, respectively. For example, when the metal portion 29 of the first housing component 20 has a three-dimensional (non-planar) shape, the first groove 211 and the second groove 212 can extend curvedly (see FIGS. 2B and 2C), and in this case, the length LI of the first groove 211 and the length L2 of the second groove 212 should include the lengths of these curved portions. Figure 1 Figure 2

[0063] As shown, in some embodiments, the width Wl of the first groove 211 and the width W2 of the second groove 212 of the first slot structure 21 fall within the range of 0.85 mm to 2 mm. In some embodiments, the width W3 of the second slot structure 31 is at least 0.2 mm. In some embodiments, the length of the first groove 211 facing the wireless communication module 90 is substantially more than one quarter of the wavelength of the radio waves emitted by the wireless communication module 90, and the length of the second groove 212 is substantially more than one half of the wavelength of the radio waves emitted by the wireless communication module 90. More specifically, when the first groove 211 is arranged substantially along the short axis of the metal portion 29 and intersects with the second groove 212 to form a cross-shaped slot as shown, and when the second groove 212 is arranged substantially along the long axis of the metal portion 29 as shown, the length LI of the first groove 211 is substantially more than one half of the wavelength of the radio waves emitted by the wireless communication module 90, and the length L2 of the second groove 212 is substantially more than 0.7 times the wavelength of the radio waves emitted by the wireless communication module 90. For example, the wavelength of a 2.4 GHz radio wave is 125 mm, and accordingly, the length of the first groove 211 is about 62.5 mm or more, and the length of the second groove 212 is about 87.5 mm or more. The length L2 of the second groove 212 can be greater than the length LI of the first groove 211. When the dimensions of the first slot structure 21 and the second slot structure 31 fall within the above-mentioned numerical ranges, the radiation pattern of the wireless communication module 90 can be effectively changed to be omni-directional (or nearly omni-directional). Conversely, when the dimensions of the first slot structure 21 and the second slot structure 31 fall outside the above-mentioned numerical ranges, the improvement effect on the radiation pattern of the wireless communication module 90 is not obvious. Figures 1 to 3 ​​​As shown, in some embodiments, the first housing component 20 can further comprise a non-metal portion 28 made of a non-metal material, which is connected to the metal portion 29 to maintain the integrity of the first housing component 20. In the embodiment shown, the non-metal portion 28 is located on the inner side of the metal portion 29 and covers the first slot structure 21 and the second slot structure 31. However, in other embodiments, the non-metal portion 28 can instead be located on the outer side of the metal portion 29, or the non-metal portion 28 can instead be filled in the first slot structure 21 and / or the second slot structure 31. In some embodiments, the non-metal portion 28 and the metal portion 29 can be two shells that are arranged in a nested manner and can be combined by adhesive fixing, snap fixing or other suitable means. In some embodiments, the metal portion 29 can be an electroplated layer on the surface of the non-metal portion 28.

[0064] Please refer to Figure 6 . Figure 6 is a schematic top view of an electronic device 15A according to another embodiment of the present application. The embodiment shown is similar to the embodiment shown in Figure 3 , except that in the embodiment shown, the first slot 211A and the second slot 212 meet at a point and are connected to each other to form a T-shaped slot. One end of the first slot 211A is connected to the second slot 212, and the other end of the first slot 211A is arranged away from the second slot 212 (for example, the other end of the first slot 211A can be connected to the outer edge of the metal portion 29). The embodiment shown is equivalent to shortening the first slot of the embodiment shown in Figure 3 , except that the first slot 211A must face the wireless communication module 90 (for example, through the top of the wireless communication module 90), and the length L1 of the first slot 211A is at least one quarter of the wavelength of the radio waves emitted by the wireless communication module 90. For example, the wavelength of a 2.4 GHz radio wave is 125 mm, and correspondingly, the length L1 of the first slot 211A is about 31.25 mm or more.

[0065] Please refer to Figure 7 . Figure 7 is a schematic top view of an electronic device 15B according to another embodiment of the present application. The embodiment shown is similar to the embodiment shown in Figure 3The difference between the embodiment shown in FIG. 15A and the embodiment shown in FIG. 15B is that in the embodiment shown in FIG. 15B, the first groove 211B is substantially arranged along the long axis direction of the metal portion 29, and the second groove 212B is substantially arranged along the short axis direction of the metal portion 29. The length LI of the first groove 211B can be greater than the length L2 of the second groove 212B. In addition, when the first groove 211B is substantially arranged along the long axis direction of the metal portion 29, the length of the first groove 211B is substantially 0.35 times or more of the wavelength of the radio wave emitted by the wireless communication module 90. For example, in the embodiment shown in FIG. 15B, the length LI of the first groove 211B is substantially 0.7 times or more of the wavelength of the radio wave emitted by the wireless communication module 90.

[0066] Please refer to Figure 8 . Figure 8 is a schematic top view of an electronic device 15C according to another embodiment of the present application. The difference between the embodiment shown in FIG. 15A and the embodiment shown in FIG. 15C is that in the embodiment shown in FIG. 15C, the first groove 211C and the second groove 212B intersect at a point and communicate with each other to form a T-shaped groove. Figure 7 The embodiment shown in FIG. 15A is equivalent to shortening the first groove of the embodiment shown in FIG. 15B. However, the first groove 211C must face the wireless communication module 90 (for example, by being above the wireless communication module 90), and the length LI of the first groove 211C is at least 0.35 times the wavelength of the radio wave emitted by the wireless communication module 90. For example, the wavelength of a 2.4 GHz radio wave is 125 mm, and accordingly, the length LI of the first groove 211C is about 43.75 mm or more. Figure 7

[0067] Please refer to Figure 9 . Figure 9 is a schematic top view of an electronic device 15D according to another embodiment of the present application. The difference between the embodiment shown in FIG. 15A and the embodiment shown in FIG. 15D is that in the embodiment shown in FIG. 15D, the first groove 211D and the second groove 212B intersect at a point and communicate with each other to form a T-shaped groove. Figure 3 ​The difference between the embodiment shown is that the metal portion 29 has two second grooves 212D separated from each other, and two first grooves 211D separated from each other, the two second grooves 212D are symmetrically arranged on both sides of the first grooves 211D and separated from the first grooves 211D (i.e. the second grooves 212D are not in communication with the first grooves 211D), and the two first grooves 211D are symmetrically arranged on both sides of the second grooves 212D and separated from the second grooves 212D. The wireless communication module 90 is arranged facing one of the first grooves 211D. The two second grooves 212D can be parallel to each other, but are not limited thereto. In this embodiment, the length L1 of each first groove 211D and the length L2 of each second groove 212D are substantially more than one fifth of the wavelength of the radio wave emitted by the wireless communication module 90, so as to effectively change the radiation pattern of the wireless communication module 90 to be omnidirectional (or nearly omnidirectional). For example, the wavelength of a 2.4 GHz radio wave is 125 mm, and correspondingly, the length L1 of each first groove 211D and the length L2 of each second groove 212D are about 25 mm or more.

[0068] In addition, in some embodiments, the metal portion 29 can have only a single first groove 211D. For example, the metal portion 29 can be provided with only the first groove 211D facing the wireless communication module 90, and the other first groove 211D is omitted. Alternatively, the metal portion 29 can be provided with the first groove 211 shown instead of the two first grooves 211D, and in such a configuration, the first groove 211 can pass through the area between the two second grooves 212D. Figure 3

[0069] Please refer to Figure 10 . Figure 10 A schematic top view of an electronic device 15E according to another embodiment of the present application is shown. The difference between this embodiment and the foregoing embodiments is that the second groove 212E includes two sections that are not parallel to each other and are substantially symmetrical, and the first groove 211E is connected to the intersection of the two sections of the second groove 212E to form a Y-shaped groove together with the second groove 212E. Such a configuration also helps to improve the radiation pattern of the wireless communication module 90.

[0070] In summary, the electronic device according to the present application includes first and second housing components. The metal portion of the first housing component is provided with a first slot structure having a cross-shaped, T-shaped, Y-shaped or other suitable symmetrical shape, and a portion of the first slot structure is arranged facing a wireless communication module inside the electronic device.
