When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.

[0028] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. The singular forms of "a", "said" and "the" used in this disclosure and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0029] In order to facilitate understanding of the technical solution of the present disclosure, the antenna and electronic device of the present disclosure are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0030] See also Figure 1As shown, an embodiment of the present disclosure provides an electronic device, which may be, for example, a mobile phone, a tablet computer, a laptop computer, a wearable device, a smart bracelet, a smart watch, a smart glasses, or other electronic products. The electronic device may include a display screen, a back cover, a metal middle frame housing 10, and an antenna. The display screen is mounted on the front of the metal middle frame housing 10, and the back cover is mounted on the back of the metal middle frame housing 10.

[0031] See also Figures 1 to 4 As shown, the antenna may include a metal middle frame shell 10, the metal middle frame shell 10 includes a middle frame side wall 11 and a battery compartment 12, the battery compartment 12 includes a battery compartment wall 122, the middle frame side wall 11 is provided with a break, the battery compartment wall 122 and the middle frame side wall 11 are spaced apart, and at least one metal connector is provided between the battery compartment wall 122 and the middle frame side wall 11. The middle frame side wall 11, the battery compartment wall 122 and the at least one metal connector enclose a cavity 21 having an opening 20. That is, at least a portion of the metal middle frame shell 10 can be used to form an antenna for an electronic device, and the metal connector can improve the sealing of the cavity antenna. When the antenna is applied to an electronic device, the battery compartment 12 can be used to accommodate the battery of the electronic device. It can be understood that, Figure 1 It is a partial schematic diagram of the interior of an electronic device after the back cover is removed. When the back cover is closed, the opening 20 of the cavity 21 can be covered. The metal middle frame shell 10 includes a middle frame body and a middle frame side wall 11 arranged around the middle frame body. A battery compartment 12 is formed on the middle frame body. Optionally, the middle frame side wall 11 and the battery compartment 12 can be made of the same metal material and integrally formed for easy processing and forming.

[0032] As can be seen from the above embodiments, the antenna of the present disclosure is formed by enclosing a cavity 21 with an opening 20 by the battery compartment 12 of the metal middle frame shell 10 and the middle frame side wall 11, thereby forming a cavity antenna with an opening 20 (such as Figure 3 As shown in the box), the risk of uncertain electrical connection can be reduced, and the sealing of the cavity 21 can be kept intact, thereby increasing the performance of the entire cavity antenna, improving antenna performance, and reducing costs and mass production risks. In this way, the antenna is applied to an electronic device, so that the antenna can be located on the side of the electronic device instead of the top or bottom corner. The cavity antenna does not need to worry about the clearance problem between the side wall of the middle frame (which can be understood as suspended metal) and the middle frame body. When the user plays games in horizontal mode, it is not easy to hold the hand in the position of the cavity antenna, which improves the antenna performance and signal when playing games in horizontal mode, and reduces the jamming phenomenon when playing games in horizontal mode.

[0033] In some optional embodiments, the battery compartment 12 further includes a battery compartment body 121, and a battery compartment wall 122 is disposed around the battery compartment body 121. It can be understood that the battery compartment body 121 is used to accommodate the battery of the electronic device, and the outer wall of the battery compartment wall 122 and the inner wall of the middle frame side wall 11 are enclosed to form the cavity 21.

[0034] Furthermore, the battery compartment wall 122 and the middle frame side wall 11 are spaced apart. In order to improve the sealing of the cavity antenna, at least one metal connector may be provided between the battery compartment wall 122 and the middle frame side wall 11. The middle frame side wall 11, the battery compartment wall 122 and the at least one metal connector enclose the cavity 21. In this way, the sealing of the cavity 21 can be improved by the cooperation of the metal connector with the middle frame side wall 11 and the battery compartment wall 122, thereby improving the antenna performance.

[0035] In one embodiment, at least one metal connector includes a first metal connector 31 and a second metal connector 32, and the first metal connector 31 and the second metal connector 32 are arranged between the battery compartment wall 122 and the middle frame side wall 11 along the length direction of the middle frame side wall 11. The middle frame side wall 11, the battery compartment wall 122, the first metal connector 31 and the second metal connector 32 enclose a cavity 21. In this way, a rectangular cavity antenna with four closed sides and two open sides connected is formed, which can improve the sealing of the cavity 21 and thus improve the antenna performance.

[0036] In another embodiment, on the basis that at least one metal connector includes a first metal connector 31 and a second metal connector 32, at least one metal connector may further include a third metal connector, and the third metal connector is connected from the front of the metal middle frame shell 10 to the middle frame side wall 11, the battery compartment wall 122, the first metal connector 31 and the second metal connector 32. The middle frame side wall 11, the battery compartment wall 122, the first metal connector 31, the second metal connector 32 and the third metal connector enclose a cavity 21, and the opening 20 of the cavity 21 faces the back of the metal middle frame shell 10, that is, toward the back cover. In this way, a rectangular cavity antenna with five closed sides and one open side is formed, which can improve the sealing and structural strength of the cavity 21, and can solve the performance degradation caused by hand holding while also strengthening the strength of the structure, thereby improving the antenna performance.

[0037] It should be noted that the purpose of adjusting the antenna size, antenna position and antenna frequency band can be achieved by adjusting the spacing between the first metal connector 31 and the second metal connector 32 and the dielectric constant setting of the metal material to change the opening size of the cavity, the size of the cavity and the position of the antenna. For example, by making the spacing between the first metal connector 31 and the second metal connector 32 as long as possible and setting them in the middle position between the top and bottom sides of the electronic device, the cavity antenna can generate the resonant frequency of GPS+WiFi2.4G and effectively prevent the problem of poor antenna performance due to hand holding.

[0038] Optionally, the middle frame side wall 11, the battery compartment 12 and at least one metal connector can be made of the same metal material and formed as one piece, that is, the middle frame side wall 11, the battery compartment 12, the first metal connector 31, the second metal connector 32 and the third metal connector can be made of the same metal material and formed as one piece to facilitate processing and forming.

[0039] In some optional embodiments, the antenna may further include a circuit board 40, which is mounted on the metal middle frame housing 10 and electrically connected to the metal middle frame housing 10. It is understandable that the circuit board 40 may be a printed circuit board (PCB), and the circuit board 40 may be used to feed the cavity antenna. The circuit board 40 may be connected to the metal middle frame housing 10 by screw locking or the like. The display screen and the circuit board 40 may be electrically connected by conductive parts such as missile foam and shrapnel.

[0040] Optionally, the circuit board 40 is provided with a metal conductive member 41, and the metal conductive member 41 is in contact with the metal middle frame housing 10. The metal conductive member 41 can be a gold-plated conductive foam, conductive silicone, conductive cloth pasted on the circuit board 40, a metal spring welded on the circuit board 40, etc. In this way, a cavity antenna with an opening is formed by enclosing the side wall of the middle frame and the wall of the battery compartment, and the antenna is fed by the metal conductive member 41 on the side of the circuit board 40.

[0041] It can be understood that the metal middle frame shell 10 itself can serve as the grounding point of the cavity antenna, and the metal conductive part 41 can be set on the circuit board 40 close to the battery compartment 12, so that the feeding point is as close to the radiating body of the cavity antenna as possible at the end of the cavity. In this way, the grounding point can be closer to the feeding point, achieving a shorter conductive path.
