[0026] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described in the present application are only a part of the embodiments, not all of the embodiments. Based on the embodiments provided in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present application.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive, independent, or alternative to other embodiments. It can be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0028] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example: a component or device including one or more parts is not limited to the one or more parts listed, but optionally includes one or more parts that are not listed but inherent to the exemplified product, or one or more parts that it should have based on the described function.

[0029] An embodiment of the present application provides an electronic device 1. The electronic device 1 includes but is not limited to mobile phones, telephones, televisions, tablet computers (Pads), personal computers, laptop computers (Personal Computers, PCs), vehicle-mounted devices, headphones, watches, wearable devices, and other devices that can send and receive electromagnetic wave signals. In the schematic diagram of the embodiment of the present application, the electronic device 1 is illustrated as a mobile phone. It can be understood that it should not be understood as a limitation on the electronic device 1 provided in the embodiment of the present application. The electronic device 1 provided in the embodiment of the present application is introduced. Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 A back view of an electronic device in a vertical screen state provided by an embodiment of the present application; Figure 2 for Figure 1 The electronic device is shown in a front view in a landscape orientation; Figure 3 for Figure 1 A rear view of a portion of the structure of the electronic device shown; Figure 4 for Figure 3 Detailed identification diagram of the electronic device shown in . The electronic device 1 includes a middle frame 30. The middle frame 30 includes a frame body 310 and a frame portion 320. The frame portion 320 is bent and connected to the periphery of the frame body 310. The frame portion 320 includes a first frame 321 and a second frame 322 that are bent and connected. The length of the second frame 322 is greater than the length of the first frame 321. The electronic device 1 also includes an antenna assembly 10. The antenna assembly 10 includes a first antenna 110. The first antenna 110 includes a first radiator 111 and a first feed source S1. The first radiator 111 is located at the second frame 322. The first radiator 111 has a first grounding terminal 1111, a first feeding point P1 and a first free end 1112 that are arranged in sequence. The first grounding terminal 1111 is electrically connected to the frame body 310 for grounding. The first free end 1112 is closer to the first frame 321 than the first ground end 1111, and the second frame 322 has a first slot 322a that defines the first free end 1112. The first feed source S1 is electrically connected to the first feed point P1 to excite the first radiator 111 to support the target frequency band. The distance d from the first slot 322a to the first frame 321 is 11 Satisfy: 30mm≤d 11 ≤65mm.

[0030] The material of the middle frame 30 generally includes metal or alloy. Therefore, the frame body 310 of the middle frame 30 constitutes at least part of the ground (also called floor or ground) of the electronic device 1 .

[0031] In this embodiment, the first radiator 111 may be, but is not limited to, a mechanical design antenna (MDA) radiator designed by a computerized numerical control machine tool (CNC) process or by using its own insert metal design process.

[0032] The length of the second frame 322 is greater than the length of the first frame 321, so the first frame 321 is a short frame in the electronic device 1, and the second frame 322 is a long frame of the electronic device 1. In the schematic diagram of this embodiment, when the electronic device 1 is in a vertical screen state, the first frame 321 is located at the top of the electronic device 1. It can be understood that in other embodiments, when the electronic device 1 is in a vertical screen state, the first frame 321 is located at the bottom of the electronic device 1.

[0033] The first grounding terminal 1111 is electrically connected to the ground electrode, and the first grounding terminal 1111 is grounded in a manner that is, but not limited to, electrically connected to the ground electrode through a grounding member. The grounding member may be, but not limited to, a conductive spring, or a conductive glue, or a conductive screw, or a connecting rib, etc. In this embodiment, the grounding member is a connecting rib as an example for illustration.

[0034] The first feed source S1 may be electrically connected to the first feed point P1 by, but not limited to, a feed component, etc. The feed component may be, but not limited to, a conductive spring, conductive glue, conductive screw, or connecting rib, etc.

[0035] The target frequency band includes but is not limited to a low frequency band (such as 700 MHz to 960 MHz), or a WiFi 2.4G frequency band, or an N78 frequency band.

[0036] When the target frequency band includes but is not limited to a low frequency band, a WiFi 2.4G band, or an N78 band, the communication requirements of the first antenna 110 in the low frequency band, the WiFi 2.4G band, or the N78 band can be met.

[0037] In one embodiment, the target frequency band includes a low frequency band, and the length of the first radiator 111 is 40 mm to 45 mm. When the electronic device 1 is a mobile phone, the length of the electronic device 1 in the extension direction of the second frame 322 (that is, the length of the electronic device 1) can be, but is not limited to, 170 mm to 190 mm.

[0038] The first free end 1112 is closer to the first frame 321 than the first ground end 1111. Therefore, when the electronic device 1 is in the portrait mode and the first frame 321 is located at the top of the electronic device 1, the opening of the first radiator 111 faces upward. In other embodiments, when the electronic device 1 is in the portrait mode and the first frame 321 is located at the bottom of the electronic device 1, the opening of the first radiator 111 faces downward.

[0039] The second frame 322 has a first slit 322a defining the first free end 1112. In this embodiment, the first slit 322a penetrates the surface of the second frame 322 away from the frame body 310.

[0040] The distance d between the first gap 322a and the first frame 321 is 11 It can be but is not limited to 30mm, or 31mm, or 32mm, or 33mm, or 34mm, or 35mm, or 36mm, or 37mm, or 38mm, or 39mm, or 40mm, or 41mm, or 42mm, or 43mm, or 44mm, or 45mm, or 46mm, or 47mm, or 48mm, or 49mm, or 50mm, or 51mm, or 52mm, or 53mm, or 54mm, or 55mm, or 56mm, or 57mm, or 58mm, or 59mm, or 60mm, or 61mm, or 62mm, or 63mm, or 64mm, or 65mm.

[0041] The distance d between the first gap 322a and the first frame 321 is 11 Satisfy: 30mm≤d 11 ≤65mm, therefore, when the electronic device 1 is in a landscape state and is held with both hands (for example, in a landscape state and held with both hands for playing games), the first gap 322a is not easily blocked by the user's hand, so that the radiation energy of the first antenna 110 when supporting the target frequency band is less or even not absorbed by the user's hand. Therefore, when the electronic device 1 provided in the embodiment of the present application is in a landscape state and held with both hands, the first antenna 110 of the antenna assembly 10 has better radiation performance in the target frequency band and a higher network experience. For example, when the user is in a landscape state and in a game scenario, the target frequency band can be better utilized to transmit and receive signals, which can meet the user's demand for a smooth gaming experience.

[0042] In summary, in the electronic device 1 provided in the embodiment of the present application, the first radiator 111 of the first antenna 110 in the antenna assembly 10 is located at the second frame 322, and the distance d from the first gap 322a of the first free end 1112 of the first radiator 111 to the first frame 321 is defined. 11 Satisfy: 30mm≤d 11 Therefore, when the electronic device 1 provided in the embodiment of the present application is in a horizontal screen state and is held by both hands, the first gap 322a is not easily blocked by the user's hands, the first antenna 110 of the antenna assembly 10 has good radiation performance in the target frequency band, and the network fluency experience is high.

[0043] For further information, see Figure 3 and Figure 4 A first gap 322 b is defined between the second frame 322 and the frame body 310 , and the first gap 322 b is connected to the first gap 322 a to define the first radiator 111 in the second frame 322 .

[0044] The extension direction of the first gap 322b is the same or approximately the same as the extension direction of the second frame 322. The first gap 322b may be formed by, but is not limited to, a CNC or MDA process.

[0045] The electronic device 1 provided in the embodiment of the present application has a first gap 322b between the second frame 322 and the frame body 310, and the first gap 322b is connected to the first gap 322a to define the first radiator 111 in the second frame 322. Therefore, the first radiator 111 can reuse the second frame 322 of the middle frame 30, saving components of the electronic device 1.

[0046] See also Figure 4 and Figure 5 , Figure 5 A schematic diagram of the line width of the first gap in the antenna assembly of the electronic device provided in another embodiment. The line width w1 of the first gap 322b satisfies: 2.0mm≤w1≤3.5mm.

[0047] The line width w1 of the first gap 322b may be, but is not limited to, 2.0 mm, or 2.1 mm, or 2.2 mm, or 2.3 mm, or 2.4 mm, or 2.5 mm, or 2.6 mm, or 2.7 mm, or 2.8 mm, or 2.9 mm, or 3.0 mm, or 3.1 mm, or 3.2 mm, or 3.3 mm, or 3.4 mm, or 3.5 mm.

[0048] Generally speaking, the first gap 322b constitutes part of the clearance of the first antenna 110. When the line width w1 of the first gap 322b is small, the clearance of the first antenna 110 is small, and the performance of the first antenna 110 when supporting the target frequency band is relatively poor. When the line width w1 of the first gap 322b is large, the structural strength of the middle frame 30 is weak. In addition, when the electronic device 1 includes a battery, the line width w1 of the first gap 322b is large, which will also occupy the space of the battery, so that the capacity of the battery is limited. In addition, when the line width w1 of the first gap 322b is large, it will also cause greater difficulty in waterproofing the electronic device 1.

[0049] In the electronic device 1 provided in the embodiment of the present application, the line width w1 of the first gap 322b satisfies: 2.0mm≤w1≤3.5mm, which, on the one hand, allows the first antenna 110 to have a larger clearance, and the first antenna 110 has better antenna performance in the target frequency band; on the other hand, allows the middle frame 30 of the electronic device 1 to have a greater structural strength. In addition, when the electronic device 1 includes a battery, the line width w1 of the first gap 322b satisfies: 2.0mm≤w1≤3.5mm, which can also allow the battery to have a larger space and is conducive to maintaining the waterproof performance of the electronic device 1.

[0050] See also Figure 6 , Figure 6 for Figure 3 Schematic diagram of the distance from the first ground terminal to the first frame. When the electronic device 1 is in the vertical screen state, the first frame 321 is located at the top of the electronic device 1. The distance d from the first ground terminal 1111 to the first frame 321 is 12 Satisfy: 70mm≤d 12 ≤110mm.

[0051] The distance d between the first ground terminal 1111 and the first frame 321 is 12 It can be, but is not limited to, 70 mm, 75 mm, 80 mm, 85 mm, 90 mm, 95 mm, 100 mm, 105 mm, or 110 mm.

[0052] When the electronic device 1 is in a portrait state, the first frame 321 is located at the top of the electronic device 1. As can be seen from the previous description, the first free end 1112 is closer to the first frame 321 than the first ground end 1111. Therefore, when the electronic device 1 is in a portrait state, the first free end 1112 is closer to the top of the electronic device 1, while the first ground end 1111 is away from the top of the electronic device 1. The first ground end 1111 is away from the top of the electronic device 1, so that when the electronic device 1 is in a portrait state and in a head-hand scenario (for example, a scenario where the hand holds the electronic device 1 and places it next to the head to make a call), the first ground end 1111 is relatively far away from the user's head, the attenuation of the first antenna 110 in the target frequency band is small, and the first antenna 110 has better antenna performance in the target frequency band.

[0053] The distance d between the first ground terminal 1111 and the first frame 321 is 12 Satisfy: 70mm≤d 12 ≤110mm, so that when the electronic device 1 is in the portrait mode, the first grounding end 1111 is far from the top of the electronic device 1. When the electronic device 1 is in the portrait mode, in a head-hand scenario, the first grounding end 1111 is relatively far from the user's head, the attenuation of the first antenna 110 in the target frequency band is small, and the first antenna 110 has good antenna performance in the target frequency band.

[0054] In addition, it should be noted that, in the electronic device 1 provided in the embodiment of the present application, the distance d from the first ground terminal 1111 to the first frame 321 is 12 Satisfy: 70mm≤d 12 ≤110mm not only allows the electronic device 1 shown to have better performance in the target frequency band in the portrait mode and in the head-hand scenario, but also allows the antenna performance in the target frequency band to be better in other scenarios, such as free space, or in the landscape mode with the electronic device 1 held in both hands.

The electronic device 1 includes a middle frame 30. The middle frame 30 includes a frame body 310 and a frame portion 320. The frame portion 320 is bent and connected to the periphery of the frame body 310. The frame portion 320 includes a first frame 321 and a second frame 322 that are bent and connected. The length of the second frame 322 is greater than the length of the first frame 321. The electronic device 1 also includes an antenna assembly 10. The antenna assembly 10 includes a first antenna 110. The first antenna 110 includes a first radiator 111 and a first feed source S1. The first radiator 111 is located at the second frame 322. The first radiator 111 has a first grounding terminal 1111, a first feeding point P1 and a first free end 1112 that are arranged in sequence. The first grounding terminal 1111 is electrically connected to the frame body 310 for grounding. The first free end 1112 is closer to the first frame 321 than the first ground end 1111, and the second frame 322 has a first slot 322a that defines the first free end 1112. The first feed source S1 is electrically connected to the first feed point P1 to excite the first radiator 111 to support the target frequency band. The distance d from the first slot 322a to the first frame 321 is 11 Satisfy: 30mm≤d 11 ≤65mm(See Fig. 9 ).

[0056] In addition, in this embodiment, the middle frame 30 further includes a third frame 323. The third frame 323 is bent and connected to the first frame 321, the length of the third frame 323 is greater than the length of the first frame 321, and the third frame 323 is arranged opposite to the second frame 322. The antenna assembly 10 further includes a second antenna 120. The second antenna 120 includes a second radiator 121 and a second feed source S2. The second radiator 121 is located on the third frame 323. The third radiator has a second grounding end 1211, a second feeding point P2 and a second free end 1212 arranged in sequence. The second grounding end 1211 is grounded, the second free end 1212 is adjacent to the first frame 321 compared to the second grounding end 1211, and the third frame 323 has a second slit 323a that defines the second free end 1212. The second feed source S2 is electrically connected to the second feeding point P2 to support the second radiator 121 to support the target frequency band. The distance d between the second gap 323a and the first frame 321 is 21 Satisfy: 30mm≤d 21 ≤65mm.

[0057] In this embodiment, the second radiator 121 may be, but is not limited to, an antenna radiator formed by a CNC process or an MDA process.

[0058] The length of the third frame 323 is greater than the length of the first frame 321, so the first frame 321 is a short frame in the electronic device 1, and the third frame 323 is a long frame of the electronic device 1. In the schematic diagram of this embodiment, when the electronic device 1 is in a vertical screen state, the first frame 321 is located at the top of the electronic device 1. It can be understood that in other embodiments, when the electronic device 1 is in a vertical screen state, the first frame 321 is located at the bottom of the electronic device 1.

[0059] The second grounding terminal 1211 is electrically connected to the ground electrode, and the second grounding terminal 1211 is grounded in a manner that is, but not limited to, electrically connected to the ground electrode through a grounding member. The grounding member may be, but not limited to, a conductive spring, or a conductive glue, or a conductive screw, or a connecting rib, etc. In this embodiment, the grounding member is a connecting rib as an example for illustration.

[0060] The second feed source S2 may be electrically connected to the second feed point P2 by, but is not limited to, the second feed source S2 being electrically connected to the second feed point P2 via a feeder, etc. The feeder may be, but is not limited to, a conductive spring, conductive glue, conductive screw, connecting rib, etc.

[0061] In one embodiment, the target frequency band includes a low frequency band, and the length of the second radiator 121 is 40 mm to 45 mm. When the electronic device 1 is a mobile phone, the length of the electronic device 1 in the extension direction of the third frame 323 (that is, the length of the electronic device 1) can be, but is not limited to, 170 mm to 190 mm.

[0062] The second free end 1212 is closer to the first frame 321 than the second ground end 1211. Therefore, when the electronic device 1 is in the portrait mode and the first frame 321 is located at the top of the electronic device 1, the opening of the second radiator 121 faces upward. In other embodiments, when the electronic device 1 is in the portrait mode and the first frame 321 is located at the bottom of the electronic device 1, the opening of the second radiator 121 faces downward.

[0063] The third frame 323 has a second slit 323a defining the second free end 1212. In this embodiment, the second slit 323a penetrates the surface of the third frame 323 away from the frame body 310.

[0064] The distance d between the second gap 323a and the first frame 321 is21 It can be but is not limited to 30mm, or 31mm, or 32mm, or 33mm, or 34mm, or 35mm, or 36mm, or 37mm, or 38mm, or 39mm, or 40mm, or 41mm, or 42mm, or 43mm, or 44mm, or 45mm, or 46mm, or 47mm, or 48mm, or 49mm, or 50mm, or 51mm, or 52mm, or 53mm, or 54mm, or 55mm, or 56mm, or 57mm, or 58mm, or 59mm, or 60mm, or 61mm, or 62mm, or 63mm, or 64mm, or 65mm.

[0065] The distance d between the second gap 323a and the first frame 321 is 21 Satisfy: 30mm≤d 21 ≤65mm, therefore, when the electronic device 1 is in a landscape state and is held with both hands (for example, in a landscape state and held with both hands for playing games), the second gap 323a is not easily blocked by the user's hand, so that the radiation energy of the second antenna 120 when supporting the target frequency band is less or even not absorbed by the user's hand. Therefore, when the electronic device 1 provided in the embodiment of the present application is in a landscape state and held with both hands, the second antenna 120 of the antenna assembly 10 has better radiation performance in the target frequency band and a higher network experience. For example, when the user is in a landscape state and in a game scenario, the target frequency band can be better utilized to transmit and receive signals, which can meet the user's demand for a smooth gaming experience.

[0066] In summary, in the electronic device 1 provided in the embodiment of the present application, the second radiator 121 of the second antenna 120 in the antenna assembly 10 is located at the third frame 323, and the distance d from the second slit 323a of the second free end 1212 of the second radiator 121 to the first frame 321 is defined. 21 Satisfy: 30mm≤d 21 Therefore, when the electronic device 1 provided in the embodiment of the present application is in a horizontal screen state and held by both hands, the second gap 323a is not easily blocked by the user's hands, and the second antenna 120 of the antenna assembly 10 has good radiation performance in the target frequency band, and the network experience is high.

[0067] In addition, in this embodiment, the first antenna 110 supports the target frequency band, and the second antenna 120 also supports the target frequency band, so the antenna assembly 10 of the electronic device 1 has good antenna performance in the target frequency band. When the target frequency band includes a low-frequency band, the first antenna 110 and the second antenna 120 in the antenna assembly 10 of the electronic device 1 are also referred to as dual low-frequency antennas. When the target frequency band includes a WiFi 2.4G band, the first antenna 110 and the second antenna 120 in the antenna assembly 10 of the electronic device 1 are also referred to as dual WiFi 2.4G antennas. When the target frequency band includes an N78 band, the first antenna 110 and the second antenna 120 in the antenna assembly 10 of the electronic device 1 are also referred to as dual N78 band antennas.

[0068] Please continue reading Figure 7 , Fig.10 and Fig.11 , Fig.10 for Figure 7 A schematic diagram of a portion of the structure of the electronic device shown; Fig.11 for Fig.10 Schematic diagram of the first gap and the second gap in the electronic device 1. The second radiator 121 also has a button hole 121a. A second gap 323b is provided between the third frame 323 and the frame body 310. The second gap 323b is connected to the second gap 323a to define the second radiator 121 in the third frame 323, and the second gap 323b is connected to the button hole 121a. The electronic device 1 also includes a button 70, and the button 70 is at least partially accommodated in the button hole 121a and the second gap 323b. Wherein, the line width w2 of the second gap 323b satisfies: w2>w1.

[0069] The extending direction of the second gap 323b is the same or approximately the same as the extending direction of the third frame 323. The second gap 323b may be formed by, but is not limited to, a CNC or MDA process.

[0070] The electronic device 1 provided in the embodiment of the present application has a second gap 323b between the third frame 323 and the frame body 310, and the second gap 323b is connected to the second gap 323a to define the second radiator 121 in the third frame 323. Therefore, the second radiator 121 can reuse the third frame 323 of the middle frame 30, saving components of the electronic device 1.

[0071] In this embodiment, the button hole 121a penetrates the outer surface and the inner surface of the second radiator 121. In addition, the button hole 121a is also connected to the second gap 323b.

[0072] The button 70 of the electronic device 1 may be, but is not limited to, a power button or a volume button. In this embodiment, the electronic device 1 includes two buttons 70 as an example, which can be immediately understood and should not be understood as a limitation on the embodiment of the present application. In other embodiments, the electronic device 1 may also include one button 70, or a number of buttons 70 greater than or equal to two.

[0073] The line width w2>w1 of the second gap 323b, on the one hand, can allow the second radiator 121 to have a relatively large clearance, so that the second antenna 120 has better antenna performance in the target frequency band; on the other hand, the second gap 323b can accommodate part of the button 70, so that the button 70 does not occupy too much space inside the electronic device 1, thereby facilitating the assembly of other components of the electronic device 1.

[0074] Please continue reading Fig.11 , under the premise of satisfying w2>w1, the line width w2 of the second gap 323b satisfies: 2.5mm≤w2≤3.5mm.

[0075] The line width w2 of the second gap 323b may be, but is not limited to, 2.5 mm, or 2.6 mm, or 2.7 mm, or 2.8 mm, or 2.9 mm, or 3.0 mm, or 3.1 mm, or 3.2 mm, or 3.3 mm, or 3.4 mm, or 3.5 mm.

[0076] Generally speaking, the second gap 323b constitutes part of the clearance of the second antenna 120. When the line width w2 of the second gap 323b is small, the clearance of the second antenna 120 is small, and the performance of the second antenna 120 in supporting the target frequency band is relatively poor. When the line width w2 of the second gap 323b is large, the structural strength of the middle frame 30 is weak. In addition, when the electronic device 1 includes a battery 800 (see Fig.12 ), the line width w2 of the second gap 323b is large, which will also occupy the space of the battery 800, so that the capacity of the battery 800 is limited. In addition, when the line width w2 of the second gap 323b is large, it will also cause greater difficulty in waterproofing the electronic device 1.

[0077] In the electronic device 1 provided in the embodiment of the present application, the line width w2 of the second gap 323b satisfies: 2.5mm≤w2≤3.5mm. On the one hand, the second antenna 120 has a larger clearance, and the second antenna 120 has better antenna performance in the target frequency band; on the other hand, the middle frame 30 of the electronic device 1 has a larger structural strength. In addition, when the electronic device 1 includes a battery 800, the line width w2 of the second gap 323b satisfies: 2.5mm≤w2≤3.5mm, which can also allow the battery 800 to have a larger space and is conducive to maintaining the waterproof performance of the electronic device 1. In addition, the line width w2 of the second gap 323b satisfies: 2.5mm≤w2≤3.5mm, so that part of the button 70 can be accommodated in the second gap 323b, so that the button 70 does not occupy too much space inside the electronic device 1, which is convenient for the assembly of other components of the electronic device 1.

[0078] Please continue reading Fig. 9 When the electronic device 1 is in a vertical screen state, the first frame 321 is located at the top of the electronic device 1. The target frequency band includes a low frequency band, and the distance d from the second ground terminal 1211 to the first frame 321 is 22 Satisfy: 70mm≤d 22 ≤110mm.

[0079] The distance d between the second ground terminal 1211 and the first frame 321 is 22 It can be, but is not limited to, 70 mm, 75 mm, 80 mm, 85 mm, 90 mm, 95 mm, 100 mm, 105 mm, or 110 mm.

[0080] When the electronic device 1 is in a portrait state, the first frame 321 is located at the top of the electronic device 1. As can be seen from the previous description, the second free end 1212 is closer to the first frame 321 than the second ground end 1211. Therefore, when the electronic device 1 is in a portrait state, the second free end 1212 is closer to the top of the electronic device 1, while the second ground end 1211 is away from the top of the electronic device 1. The second ground end 1211 is away from the top of the electronic device 1, so that when the electronic device 1 is in a portrait state and in a head-hand scenario (for example, a scenario where the hand holds the electronic device 1 next to the head to make a call), the second ground end 1211 is relatively far away from the user's head, the attenuation of the second antenna 120 in the target frequency band is small, and the second antenna 120 has better antenna performance in the target frequency band.

[0081] The distance d between the second ground terminal 1211 and the first frame 321 is22 Satisfy: 70mm≤d 22 ≤110mm, so that when the electronic device 1 is in the portrait mode, the second grounding end 1211 is far from the top of the electronic device 1. When the electronic device 1 is in the portrait mode, in a head-hand scenario, the second grounding end 1211 is relatively far from the user's head, the attenuation of the second antenna 120 in the target frequency band is small, and the second antenna 120 has good antenna performance in the target frequency band.

[0082] In addition, it should be noted that, in the electronic device 1 provided in the embodiment of the present application, the distance d from the second ground terminal 1211 to the first frame 321 is 22 Satisfy: 70mm≤d 22 ≤110mm not only allows the electronic device 1 shown to have better performance in the target frequency band in the portrait mode and in the head-hand scenario, but also allows the antenna performance in the target frequency band to be better in other scenarios, such as free space, or in the landscape mode with the electronic device 1 held in both hands.

[0083] See also Fig.12 , Fig.12 A partial structural diagram of an electronic device provided for another embodiment of the present application. In an embodiment, the electronic device 1 further includes a battery 800. The battery 800 is carried by the frame body 310. In addition, the battery 800 is disposed between the first radiator 111 and the second radiator 121. The battery 800 is used to power electrical devices in the electronic device 1. The battery 800 is disposed between the first radiator 111 and the second radiator 121. The electronic device 1 further includes a rear camera 810, and the rear camera 810 is disposed adjacent to the second radiator 121. The electronic device 1 further includes a front camera 820 and a receiver 830. The front camera 820 and the receiver 830 are both disposed adjacent to the first frame 321.

[0084] It should be noted that, in other embodiments, whether the electronic device 1 includes a battery 800, a rear camera 810, a front camera 820, a receiver 830, etc. should not be understood as a limitation on the antenna assembly 10 in the electronic device 1 provided in the embodiments of the present application.

[0085] See also Fig.13 , Fig.13A circuit block diagram of an electronic device provided in one embodiment of the present application. The electronic device 1 further includes a processor 20. The processor 20 is used to control one of the first antenna 110 and the second antenna 120 to be a transmitting antenna of the target frequency band when the electronic device 1 is in a horizontal screen state, wherein the antenna performance of the one when supporting the target frequency band is better than the antenna performance of the other of the first antenna 110 and the second antenna 120 when supporting the target frequency band.

[0086] The antenna performance may be, but is not limited to, radiation efficiency, etc. The processor 20 is used to control one of the first antenna 110 and the second antenna 120 to be a transmitting antenna of the target frequency band when the electronic device 1 is in a horizontal screen state, wherein the antenna performance of the one when supporting the target frequency band is better than the antenna performance of the other of the first antenna 110 and the second antenna 120 when supporting the target frequency band, and the specific situation is described as follows.

[0087] When the electronic device 1 is in a horizontal screen state, if the antenna performance of the first antenna 110 when supporting the target frequency band is better than the antenna performance of the second antenna 120 when supporting the target frequency band, the first antenna 110 is the transmitting antenna of the target frequency band. Correspondingly, the second antenna 120 is the receiving antenna of the target frequency band. When the first antenna 110 is the transmitting antenna of the target frequency band, the first antenna 110 can transmit electromagnetic wave signals of the target frequency band, and the first antenna 110 can also receive electromagnetic wave signals of the target frequency band. When the second antenna 120 is the receiving antenna of the target frequency band, the second antenna 120 can receive electromagnetic wave signals of the target frequency band.

[0088] When the electronic device 1 is in a horizontal screen state, if the antenna performance of the second antenna 120 when supporting the target frequency band is better than the antenna performance of the first antenna 110 when supporting the target frequency band, the second antenna 120 is the transmitting antenna of the target frequency band. Correspondingly, the first antenna 110 is the receiving antenna of the target frequency band. When the second antenna 120 is the transmitting antenna of the target frequency band, the second antenna 120 can transmit electromagnetic wave signals of the target frequency band, and the second antenna 120 can also receive electromagnetic wave signals of the target frequency band. When the first antenna 110 is the receiving antenna of the target frequency band, the first antenna 110 can receive electromagnetic wave signals of the target frequency band.

[0089] The electronic device 1 further includes a processor 20. The processor 20 is used to control one of the first antenna 110 and the second antenna 120 to be a transmitting antenna of the target frequency band when the electronic device 1 is in a horizontal screen state, wherein the antenna performance of the one when supporting the target frequency band is better than the antenna performance of the other of the first antenna 110 and the second antenna 120 when supporting the target frequency band, so that when the electronic device 1 is in a horizontal screen state, the target frequency band still has good communication performance.

[0090] When the electronic device 1 is in the horizontal screen state and is held by the user with both hands, and the display screen 50 of the electronic device 1 faces the user, the electronic device 1 has two horizontal screen states according to the different positions of the first frame 321 in the electronic device 1. For the convenience of naming, the two horizontal screen states of the electronic device 1 are named the first horizontal screen state and the second horizontal screen state. Figure 7 , Figure 8 , Fig.12 , Fig.13 and Fig.14 and Fig.15 , Fig.14 A schematic diagram of an electronic device in a first horizontal screen state provided by an embodiment of the present application; Fig.15 A schematic diagram of an electronic device in a second horizontal screen state provided in one embodiment of the present application.

[0091] Specifically, see Fig.14 , when the electronic device 1 is in the first horizontal screen state, when the electronic device 1 is held by the user with both hands and the display screen 50 of the electronic device 1 faces the user, the first frame 321 is adjacent to the user's left hand. When the electronic device 1 is in the first horizontal screen state, the third frame 323 is located at the top of the electronic device 1. The second radiator 121 is located at the third frame 323. Therefore, when the electronic device 1 is in the first horizontal screen state, compared with the first radiator 111, the second radiator 121 is less likely to be blocked by the user's fingers. It can be seen that when the electronic device 1 is in the first horizontal screen state, the performance of the second antenna 120 supporting the target frequency band is better than the performance of the first antenna 110 supporting the target frequency band. Therefore, when the electronic device 1 is in the first horizontal screen state, the processor 20 controls the second antenna 120 as a transmitting antenna supporting the target frequency band, and the first antenna 110 is a receiving antenna for the target frequency band. When the electronic device 1 is in the first horizontal screen state, the processor 20 controls the second antenna 120 as a transmitting antenna supporting the target frequency band, and the first antenna 110 is a receiving antenna of the target frequency band. The electronic device 1 has better antenna performance in the target frequency band and a higher network fluency experience.

[0092] Accordingly, see Fig.15 , when the electronic device 1 is in the second horizontal screen state, when the electronic device 1 is held by the user with both hands and the display screen 50 of the electronic device 1 faces the user, the first frame 321 is adjacent to the user's right hand. When the electronic device 1 is in the first horizontal screen state, the second frame 322 is located at the top of the electronic device 1. And the first radiator 111 is located at the second frame 322. Therefore, when the electronic device 1 is in the second horizontal screen state, compared with the second radiator 121, the first radiator 111 is less likely to be blocked by the user's fingers. It can be seen that when the electronic device 1 is in the second horizontal screen state, the performance of the first antenna 110 supporting the target frequency band is better than the performance of the second antenna 120 supporting the target frequency band. Therefore, when the electronic device 1 is in the second horizontal screen state, the processor 20 controls the first antenna 110 as a transmitting antenna supporting the target frequency band, and the second antenna 120 is a receiving antenna for the target frequency band. When the electronic device 1 is in the second horizontal screen state, the processor 20 controls the first antenna 110 as a transmitting antenna supporting the target frequency band, and the second antenna 120 is a receiving antenna of the target frequency band. The electronic device 1 has better antenna performance in the target frequency band and a higher network fluency experience.

[0093] It can be seen that when the electronic device 1 is in the first horizontal screen state, the performance of the second antenna 120 in supporting the target frequency band is better than the performance of the first antenna 110 in supporting the target frequency band. The processor 20 maintains or switches the second antenna 120 as the main transmitting antenna for transmitting electromagnetic wave signals in the target frequency band.

[0094] When the electronic device 1 is in the second horizontal screen state, the performance of the first antenna 110 in supporting the target frequency band is better than the performance of the second antenna 120 in supporting the target frequency band. The processor 20 maintains or switches the first antenna 110 as the main transmitting antenna for transmitting electromagnetic wave signals in the target frequency band.

[0095] It can be seen that when the electronic device 1 is in the first horizontal screen state and the second horizontal screen state, the performance of the first antenna 110 supporting the target frequency band and the performance of the second antenna 120 supporting the target frequency band are complementary. Through the horizontal screen state of the electronic device 1, the processor 20 can intelligently maintain or switch the first antenna 110 or the second antenna 120 as the main transmitting antenna of the target frequency band according to the state of the electronic device 1.

[0096] Specifically, when the electronic device 1 changes from the first horizontal screen state to the second horizontal screen state, the processor 20 switches the transmitting antenna supporting the target frequency band from the second antenna 120 to the first antenna 110. When the electronic device 1 switches from the second horizontal screen state to the first horizontal screen state, the processor 20 switches the transmitting antenna supporting the target frequency band from the first antenna 110 to the second antenna 120. Therefore, the processor 20 can switch the second antenna 120 or the first antenna 110 as the main transmitting antenna according to the posture of the electronic device 1, and can achieve complementary antenna performance in the first horizontal screen state and the second horizontal screen state.

[0097] Please continue reading Fig.12 , the frame portion 320 of the middle frame 30 also includes a fourth frame 324 facing away from the first frame 321. The fourth frame 324 is connected to the second frame 322 by bending, and the fourth frame 324 is connected to the third frame 323 by bending. The electronic device 1 also includes a Universal Serial Bus (UBS) interface. The serial bus interface is referred to as a USB port 840. The USB port 840 is arranged adjacent to the fourth frame 324. When the electronic device 1 is in the first horizontal screen state, the USB port 840 faces right, so the first horizontal screen state is also called the horizontal screen USB port right-facing state. When the electronic device 1 is in the second horizontal screen state, the USB port 840 faces left, so the second horizontal screen state is also called the horizontal screen USB port left-facing state.

[0098] Next, the electronic device 1 provided in the embodiment of the present application is simulated.

[0099] See also Fig.16 , Fig.16 This is a schematic diagram of the total radiation efficiency of the antenna system of the first antenna in an electronic device provided in one embodiment of the present application. For the convenience of illustration, Fig.16 (a) is a color image. Fig.16 (b) in Fig.16 In this simulation diagram, the horizontal axis is the frequency (Frequency), the unit is GHz, and the vertical axis is the system total radiation efficiency (System Total Efficiency), the unit is dB. The simulation is performed by taking the target frequency band including the low frequency band as an example. Fig.16 The green curve in (a) is a system total radiation efficiency curve of the first antenna 110 supporting the target frequency band when the electronic device 1 is in free space; Fig.16 The red curve in (a) is a system total radiation efficiency curve of the first antenna 110 supporting the target frequency band in free space (FS) when the electronic device 1 is in the second horizontal screen state (also called USB facing left).

[0100] See also Fig.17 , Fig.17 This is a schematic diagram of the total radiation efficiency of the antenna system of the second antenna in an electronic device provided in one embodiment of the present application. For the convenience of illustration, Fig.17 (a) is a color image. Fig.17 (b) in Fig.17 In this simulation diagram, the horizontal axis is the frequency (Frequency), the unit is GHz, and the vertical axis is the system total radiation efficiency (System Total Efficiency), the unit is dB. The simulation is performed by taking the target frequency band including the low frequency band as an example. Fig.17 The blue curve in (a) is a system total radiation efficiency curve of the second antenna 120 supporting the target frequency band when the electronic device 1 is in free space; Fig.17 The green curve in (a) is a system total radiation efficiency curve of the second antenna 120 supporting the target frequency band in free space when the electronic device 1 is in the first horizontal screen state (also called USB facing right).

[0101] The above two simulation figures respectively give the system total radiation efficiency curve of the first antenna 110 supporting the target frequency band when the electronic device 1 is in free space and the second horizontal screen state; and give the system total radiation efficiency curve of the second antenna 120 supporting the target frequency band when the electronic device 1 is in free space and the first horizontal screen state. Compared with the electronic device 1 being in free space, when the electronic device 1 is in the second horizontal screen state, the attenuation of the system total radiation efficiency of the first antenna 110 supporting the target frequency band is smaller (about 0.5dB). Compared with the electronic device 1 of the related art, the electronic device 1 provided in the embodiment of the present application has a significant improvement in the antenna performance (such as the system total radiation efficiency) of the first antenna 110 supporting the target frequency band when it is in the second horizontal screen state.

[0102] Compared to the electronic device 1 being in free space, when the electronic device 1 is in the first horizontal screen state, the second antenna 120 supports a smaller attenuation of the total system radiation efficiency of the target frequency band (about 0.5 dB). Compared to the electronic device 1 of the related art, when the electronic device 1 provided in the embodiment of the present application is in the first horizontal screen state, the antenna performance (such as the total system radiation efficiency) of the second antenna 120 supporting the target frequency band has been significantly improved.

[0103] In summary, in the electronic device 1 provided by one embodiment of the present application, the first radiator 111 of the first antenna 110 is located in the second frame 322. From the position of the first grounding end 1111 of the first radiator 111 and the first slit 322a defining the first free end 1112, the first radiator 111 is located at the waist of the electronic device 1. Correspondingly, the second radiator 121 of the second antenna 120 is located in the third frame 323. From the position of the second grounding end 1211 of the second radiator 121 and the second slit 323a defining the second free end 1212, the second radiator 121 is located at the waist of the electronic device 1. When the electronic device 1 is in the horizontal screen state, the user's fingers cannot or almost cannot hold the first slit 322a and the second slit 323a, so that the electronic device 1 has better antenna performance in the target frequency band.

[0104] Specifically, the electronic device 1 provided in one embodiment of the present application solves the problem of antenna performance degradation caused by the antenna performance of the target frequency band being blocked and absorbed by the user's hand in the application scenario (such as a horizontal screen game scenario) when the electronic device 1 is in the horizontal screen state in the related art through the design of two antennas located at the waist of the electronic device 1. The network communication experience of the target frequency band of the electronic device 1 in the horizontal screen state is ensured. It can be understood that when the target frequency band supported by the first antenna 110 and the second antenna 120 includes a low-frequency band, the first antenna 110 and the second antenna 120 are also referred to as low-frequency antennas.

[0105] Please read further Figure 2 , the electronic device 1 provided in one embodiment of the present application further includes a display screen 50 and a back cover 60. The display screen 50 is arranged on one side of the middle frame 30. The display screen 50 is a component for realizing the display function in the electronic device 1. The back cover 60 is arranged on the other side of the middle frame 30. In other words, the back cover 60 and the display screen 50 are respectively arranged on two opposite sides of the middle frame 30. The back cover 60 cooperates with the middle frame 30 to form a receiving space to receive the functional components of the electronic device 1, such as a rear camera 810, a battery 800, etc.

[0106] It can be understood that the description of other components in the electronic device 1 should not be understood as a limitation on the antenna assembly 10 in the electronic device 1 provided in the embodiment of the present application.

[0107] The above is part of the implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
