Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a protective case and electronic device component. Background Technology

[0002] With technological advancements, mobile phones and other electronic devices with communication capabilities are becoming increasingly widespread and powerful. These devices typically include antenna components to enable their communication functions. However, the communication performance of antenna components in current electronic devices is not yet optimal and requires further improvement. Utility Model Content

[0003] In a first aspect, embodiments of this application provide a protective housing for protecting an electronic device, the electronic device including a first antenna, the first antenna including a first radiator, the first radiator being used to support a first target frequency band, and the protective housing including:

[0004] Shell base;

[0005] A first coupling element is supported on the housing base;

[0006] A first movable component, movably connected to the housing base; and

[0007] A first coupled radiator, the first coupled radiator being supported on the first movable component;

[0008] The protective shell has a first state and a second state. When the protective shell is in the first state, the first movable member is at least partially unfolded relative to the shell base, and the first coupled radiator is used to couple with and be excited to support the first target frequency band. When the protective shell is in the second state, the first movable member is folded to the shell base, the first coupled radiator is coupled with the first coupling member, and the first coupled radiator and the first coupling member are used together to be excited by the first radiator to support the first frequency band, wherein the first frequency band is different from the first target frequency band.

[0009] Secondly, embodiments of this application also provide an electronic device component, the electronic device component comprising:

[0010] An electronic device, the electronic device including a first antenna, the first antenna including a first radiator, the first radiator being used to support a first target frequency band; and

[0011] The protective case as described in the first aspect is used to protect the electronic device.

[0012] In summary, the protective shell provided in this application includes a shell base, a first coupling member, a first movable member, and a first coupled radiator. When the protective shell is in the first state, the first coupled radiator is coupled to the first radiator of the first antenna in the electronic device, and the first coupled radiator is excited by the first radiator to support the first target frequency band. Therefore, when the protective shell is in the first state, the performance of the electronic device component supporting the first target frequency band is better than the performance of the electronic device supporting the first target frequency band. Furthermore, when the protective shell is in the first state, the first movable member is deployed relative to the shell base. Since the first coupled radiator is supported by the first movable member, it is also deployed relative to the shell base. The distance between the first coupled radiator and other components in the electronic device is relatively large, the first coupled radiator has better clearance, and the first coupled radiator supports the first target frequency band with better performance. Therefore, it can be seen that when the protective shell is in the first state, the electronic device component to which the protective shell is applied has better performance in the first target frequency band.

[0013] Furthermore, when the protective shell is in the second state, the first movable member is folded to the shell base, and the first coupled radiator is coupled to the first coupling member. The first coupled radiator and the first coupling member are jointly used to be excited by the first radiator to support the first frequency band, which is different from the first target frequency band. Therefore, when the protective shell is in the second state, the distance between the first coupled radiator and the first radiator in the electronic device is relatively short, the clearance environment of the first coupled radiator is relatively harsh, and the first coupled radiator and the first coupling member jointly support the first frequency band. Thus, when the protective shell is in the second state, the adverse effects of the first coupled radiator on the first target frequency band supported by the first radiator of the electronic device can be reduced or even avoided. This ensures that when the protective shell is in the second state, the electronic device components on which the protective shell is applied still have good performance in the first target frequency band.

[0048] This application provides a protective case and an electronic device assembly according to one embodiment. The protective case and electronic device assembly provided by this application embodiment will now be described in detail.

[0049] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , Figure 1A schematic diagram of the protective shell provided in a first state according to an embodiment of this application; Figure 2 for Figure 1 The diagram shown illustrates the protective casing in its second state. Figure 3 for Figure 1 The diagram shown illustrates the application of a protective casing to electronic device components. Figure 4 for Figure 3 An exploded view of the electronic device components shown; Figure 5 One implementation method Figure 3 A schematic diagram of the first antenna of the electronic device in the electronic device components; Figure 6 (a) in the middle is Figure 2 A schematic diagram of the protective casing from one perspective; Figure 6 Image (b) is a schematic diagram from one perspective of a protective shell provided in another embodiment. Figure 3 and Figure 4 The electronic device component 1 shown is illustrated with the protective housing 10 in the first state as an example. It should not be construed as a limitation on the electronic device component 1 provided in this application. The protective housing 10 is used to protect the electronic device 30. The electronic device 30 includes a first antenna 310. The first antenna 310 includes a first radiator 311, which supports a first target frequency band. The protective housing 10 includes a housing base 110, a first coupling member 120, a first movable member 130, and a first coupled radiator 140. The first coupling member 120 is supported on the housing base 110. The first movable member 130 is movably connected to the housing base 110. The first coupled radiator 140 is supported on the first movable member 130. The protective shell 10 has a first state and a second state. When the protective shell 10 is in the first state, the first movable member 130 is at least partially unfolded relative to the shell base 110, and the first coupling radiator 140 is used to couple with the first radiator 311 and be excited to support the first target frequency band. When the protective shell 10 is in the second state, the first movable member 130 is folded with the shell base 110, the first coupling radiator 140 is coupled with the first coupling member 120, and the first coupling radiator 140 and the first coupling member 120 are used together to be excited by the first radiator 311 to support the first frequency band, wherein the first frequency band is different from the first target frequency band.

[0050] The electronic device 30 includes, but is not limited to, devices capable of transmitting and receiving electromagnetic wave signals such as mobile phones, telephones, televisions, tablet computers, cameras, personal computers, laptops, in-vehicle devices, and wearable devices such as watches. The following illustration uses a mobile phone as an example of the electronic device 30; however, this should not be construed as limiting the implementation of this application.

[0051] The electronic device 30 includes a first antenna 310, which includes a first radiator 311 and a first feed S1. The first feed S1 is electrically connected to the first radiator 311 to excite the first radiator 311 to support a first target frequency band.

[0052] The first antenna 310 can be, but is not limited to, a planar inverted F-shaped antenna (PIFA), an inverted F-shaped antenna (IFA), a loop antenna, a T-shaped antenna, a left-handed antenna, or a frame antenna. Correspondingly, the first radiator 311 can be, but is not limited to, a PIFA antenna radiator, an IFA antenna radiator, a loop antenna radiator, a T-shaped antenna radiator, or a left-handed antenna radiator. From another perspective, the first radiator 311 can be, but is not limited to, a flexible printed circuit board (FPC) antenna radiator, a laser-directed structural (LDS) antenna radiator, a printed direct structural (PDS) antenna radiator, a metal stub radiator, or a frame antenna radiator.

[0053] In the schematic diagram of this embodiment, the first antenna 310 is used as an IFA antenna, and the first radiator 311 is used as a frame antenna radiator for illustration. It should be understood that this should not be construed as a limitation on the first antenna 310 of the electronic device 30. As long as the first antenna 310 can support the first target frequency band, it is acceptable. Specifically, the first radiator 311 includes a first free end 3111 (also called an end point), a first ground end 3112, and a first feed point P1 located between the first free end 3111 and the first ground end 3112. The first ground end 3112 is grounded. The first feed source S1 is electrically connected to the first feed point P1 to excite the first radiator 311 to support the first target frequency band.

[0054] The first target frequency band may include the Wireless Fidelity (WiFi) 5G frequency band, or the WiFi 2.4G frequency band, or one or more of the following frequency bands: Low Band (LB), Middle High Band (MHB), Ultra High Band (UWB), New Radio (NR) frequency band, Global Positioning System (GPS) L1 frequency band (i.e., GPS-L1 frequency band), GPS-L5 frequency band, etc. The WiFi 5G band ranges from 5.15GHz to 5.85GHz, the WiFi 2.4G band ranges from 2.4GHz to 2.5GHz, the LB band ranges from less than 1000MHz, the MHB band ranges from greater than or equal to 1000MHz to less than 3000MHz, the UHB band ranges from greater than or equal to 3000MHz to less than 10000MHz, the GPS-L1 band has a resonant frequency of 1575MHz, and the GPS-L5 band has a resonant frequency of 1176MHz. In this embodiment, the first target frequency band is described as a mid-to-high frequency band. It should be understood that this should not be construed as a limitation on the protective casing 10 provided in this application embodiment and the electronic device component 1 on which the protective casing 10 is applied.

[0055] The protective case 10 is also called a protective sleeve. In one embodiment, the housing base 110 is disposed on at least a portion of the outer side of the electronic device 30. The housing base 110 in the protective case 10 is the main component that enables the protective case 10 to protect the electronic device 30. For example, in one embodiment, the electronic device 30 includes a display screen 330, a middle frame 340, and a back cover 350. The middle frame 340 includes a frame body and a side border. The side border is bent and connected to the periphery of the frame body. The display screen 330 is disposed on one side of the frame body, and the back cover 350 is disposed on the other side of the frame body. In one embodiment, the housing base 110 is disposed on the outer side of the back cover 350. In another embodiment, the housing base 110 is disposed on the outer side of the back cover 350 and the outer side of the side border. The housing base 110 is used to protect the back cover 350 from damage or reduce the probability of damage to the back cover 350. It is understood that the relationship between the housing base 110 and the electronic device 30 is only an example in one embodiment where the housing base 110 is disposed on at least a portion of the outer side of the electronic device 30, and should not be construed as a limitation on the embodiments of this application.

[0056] The shell substrate 110 can be light-transmitting or opaque; this application does not limit the light transmittance of the shell substrate 110 of the protective shell 10. The shell substrate 110 can transmit electromagnetic wave signals. For example, the shell substrate 110 of the protective shell 10 can be, but is not limited to, materials that can transmit electromagnetic wave signals, such as silicone, plastic, ceramic, or glass. This application does not limit the material of the shell substrate 110 of the protective shell 10.

[0057] The first coupling element 120 may be, but is not limited to, a metal sheet, a conductive coating, a conductive layer of a flexible printed circuit board (FPC), or a conductive layer of laser direct forming (LDS), etc. The metal sheet may be, but is not limited to, a steel sheet or an aluminum sheet, etc. The first coupling element 120 may be supported on the housing substrate 110 in a manner that is, but is not limited to, the first coupling element 120 being disposed on the surface of the housing substrate 110, or the first coupling element 120 being embedded in the housing substrate 110.

[0058] The first movable member 130 may be movably connected to the housing base 110 in a manner that includes, but is not limited to, a hinge connection, a pivot connection, a rebound mechanism, a turntable connection, or a pull-out connection. This application does not limit the manner in which the first movable member 130 is movably connected to the housing base 110.

[0059] The protective shell 10 has a first state and a second state. When the protective shell 10 is in the first state, the first movable member 130 is at least partially unfolded relative to the shell base 110; therefore, the first state of the protective shell 10 is also called the unfolded state or the extended state. When the protective shell 10 is in the second state, the first movable member 130 is folded away from the shell base 110; therefore, the second state is also called the folded state.

[0060] The first coupling radiator 140 may be, but is not limited to, a flexible printed circuit (FPC) antenna radiator, a laser direct structural (LDS) antenna radiator, a printed direct structural (PDS) antenna radiator, or a metal dendrite radiator. This application does not limit the type of the first coupling radiator 140.

[0061] The first coupling radiator 140 can be supported on the first movable member 130 in a manner that is, but not limited to, embedding the first coupling radiator 140 within the first movable member 130; or having the first coupling radiator 140 disposed on the surface of the first movable member 130; or having the first coupling radiator 140 connected to the first movable member 130 with a gap between them, etc. This application does not limit the manner in which the first coupling radiator 140 is supported on the first movable member 130. Since the first coupling radiator 140 is supported on the first movable member 130, the first coupling radiator 140 can move along with the movement of the first movable member 130.

[0062] When the protective shell 10 is in the first state, the first movable member 130 is deployed at least relative to the shell base 110. Since the first coupling radiator 140 is supported by the first movable member 130, the first coupling radiator 140 is also deployed relative to the shell base 110 when the protective shell 10 is in the first state. When the protective shell 10 is in the first state, the first coupling radiator 140 is coupled to the first radiator 311 of the first antenna 310 in the electronic device 30, and the first coupling radiator 140 is excited by the first radiator 311 to support the first target frequency band. Therefore, when the protective shell 10 is in the first state, the performance of the electronic device assembly 1 supporting the first target frequency band is better than the performance of the first target frequency band supported by the electronic device 30. Furthermore, when the protective shell 10 is in the first state, the first movable member 130 is deployed relative to the shell base 110. Since the first coupling radiator 140 is supported by the first movable member 130, the first coupling radiator 140 is also deployed relative to the shell base 110. The distance between the first coupling radiator 140 and other components in the electronic device 30 is relatively far, and the first coupling radiator 140 has good clearance. The first coupling radiator 140 supports better performance in the first target frequency band. Therefore, it can be seen that the protective shell 10 provided in this application embodiment, when the protective shell 10 is in the first state, provides good performance for the electronic device component 1 on which the protective shell 10 is applied in the first target frequency band.

[0063] When the electronic device 30 in the electronic device component 1 to which the protective case 10 is applied communicates with other devices (such as base stations) in the first target frequency band, the transmission power of the first target frequency band to be transmitted by the first antenna 310 of the electronic device 30 is low, thereby reducing the power consumption of the electronic device 30 when communicating with other devices using the first target frequency band and increasing the battery life of the electronic device 30.

[0064] When the protective shell 10 is in the second state, the first movable member 130 is folded relative to the shell base 110. Since the first coupled radiator 140 is supported by the first movable member 130, the first coupled radiator 140 is also folded relative to the shell base 110 when the protective shell 10 is in the second state. When the protective shell 10 is in the second state, the first coupled radiator 140 is coupled to the first coupling member 120. The first coupled radiator 140 and the first coupling member 120 are used together to be excited by the first radiator 311 to support the first frequency band. The first frequency band is different from the first target frequency band. Therefore, when the protective shell 10 is in the second state, the distance between the first coupled radiator 140 and the first radiator 311 in the electronic device 30 is relatively close, and the clearance environment of the first coupled radiator 140 is relatively harsh. If the first coupled radiator 140 and the first radiator 311 couple to generate the first target frequency band, the first target frequency band has an efficiency dip, resulting in poor performance of the first target frequency band. In the protective shell 10 provided in this application embodiment, when the protective shell 10 is in the second state, the first coupling radiator 140 is coupled to the first coupling member 120, and the first coupling radiator 140 and the first coupling member 120 jointly support the first frequency band. The first frequency band is different from the first target frequency band. Therefore, when the protective shell 10 is in the second state, the adverse effects of the first coupling radiator 140 on the first target frequency band supported by the first radiator 311 of the electronic device 30 can be reduced or even avoided. This ensures that when the protective shell 10 is in the second state, the electronic device component 1 on which the protective shell 10 is applied still has good performance in the first target frequency band.

[0065] In one embodiment, the electrical length of the first coupling radiator 140 matches the electrical length required for the first target frequency band. Therefore, when the protective shell 10 is in the first state, the first coupling radiator 140 is coupled to the first radiator 311, and the first coupling radiator 140 is excited by the first radiator 311 to support the first target frequency band. When the protective shell 10 is in the second state, when the first coupling radiator 140 is coupled to the first coupling member 120, the sum of the electrical lengths of the first coupling radiator 140 and the first coupling member 120 is mismatched with the electrical length required for the first target frequency band. Conversely, when the protective shell 10 is in the second state, the first coupling radiator 140 and the first coupling member 120 jointly support the first frequency band.

[0066] In summary, the protective housing 10 provided in this application includes a housing base 110, a first coupling member 120, a first movable member 130, and a first coupling radiator 140. When the protective housing 10 is in the first state, the first coupling radiator 140 is coupled to the first radiator 311 of the first antenna 310 in the electronic device 30, and the first coupling radiator 140 is excited by the first radiator 311 to support the first target frequency band. Therefore, when the protective housing 10 is in the first state, the performance of the electronic device component 1 supporting the first target frequency band is better than the performance of the first target frequency band supported by the electronic device 30. Furthermore, when the protective shell 10 is in the first state, the first movable member 130 is deployed relative to the shell base 110. Since the first coupling radiator 140 is supported by the first movable member 130, the first coupling radiator 140 is also deployed relative to the shell base 110. The distance between the first coupling radiator 140 and other components in the electronic device 30 is relatively far, and the first coupling radiator 140 has good clearance. The first coupling radiator 140 supports better performance in the first target frequency band. Therefore, it can be seen that the protective shell 10 provided in this application embodiment, when the protective shell 10 is in the first state, provides good performance for the electronic device component 1 on which the protective shell 10 is applied in the first target frequency band.

[0067] Furthermore, when the protective shell 10 is in the second state, the first movable member 130 is folded with the shell base 110, and the first coupling radiator 140 is coupled with the first coupling member 120. The first coupling radiator 140 and the first coupling member 120 are jointly used to be excited by the first radiator 311 to support the first frequency band, which is different from the first target frequency band. Therefore, when the protective shell 10 is in the second state, the distance between the first coupling radiator 140 and the first radiator 311 in the electronic device 30 is relatively close, and the clearance environment of the first coupling radiator 140 is relatively harsh. The first coupling radiator 140 and the first coupling member 120 jointly support the first frequency band. Therefore, when the protective shell 10 is in the second state, the adverse effects of the first coupling radiator 140 on the first target frequency band supported by the first radiator 311 of the electronic device 30 can be reduced or even avoided. This ensures that when the protective shell 10 is in the second state, the electronic device component 1 on which the protective shell 10 is applied still has good performance in the first target frequency band.

[0068] Furthermore, when the protective case 10 is applied to the electronic device assembly 1 and the protective case 10 is in the first state, the first coupled radiator 140 can guide the radiation pattern of the first antenna 310 in the electronic device 30 supporting the first target frequency band to tilt towards the direction away from the human body (also known as the opposite direction of the human body), and avoid the user's fingers touching the antenna, thereby reducing or even avoiding the performance degradation of the first target frequency band caused by the human body and hands. For example, when the electronic device 30 is not covered by the protective case 10, the electronic device 30 has a first radiation pattern in the first target frequency band; when the protective case 10 is applied to the electronic device assembly 1 and the protective case 10 is in the first state, the electronic device assembly 1 has a second radiation pattern in the first target frequency band; wherein, the second radiation pattern is tilted towards the direction away from the human body compared to the first radiation pattern. In this way, the performance degradation of the first target frequency band caused by the human body can be reduced or even avoided. In one embodiment, the protective shell 10 has a shell base 110 including a base body portion 111 and a shell frame portion 112, the shell frame portion 112 being bent and connected to the periphery of the base body portion 111. When the protective shell 10 is applied to the electronic device assembly 1, the base body portion 111 is disposed corresponding to the rear cover 350, and the shell frame portion 112 is disposed corresponding to the frame portion of the middle frame 340. The base body portion 111 has an inner surface 111a near the rear cover 350 and an outer surface 111b away from the rear cover 350, wherein the direction from the inner surface 111a to the outer surface 111b of the base body portion 111 is the direction away from the human body. In other words, when the electronic device 30 is not covered by the protective case 10, the electronic device 30 has a first radiation pattern in the first target frequency band; when the protective case 10 is applied to the electronic device assembly 1, and when the protective case 10 is in the first state, the electronic device assembly 1 has a second radiation pattern in the first target frequency band; wherein, the second radiation pattern is inclined relative to the first radiation pattern in the direction from the inner surface 111a of the substrate body portion 111 to the outer surface 111b.

[0069] Furthermore, when the protective shell 10 is applied to the electronic device assembly 1, the first coupling radiator 140 in the protective shell 10 and the first radiator 311 in the electronic device 30 are connected by spatial coupling rather than by circuit design branches. Therefore, the design complexity and manufacturing cost of the protective shell 10 can be greatly reduced. Moreover, when the protective shell 10 is applied to the electronic device assembly 1, there are no additional requirements for the electronic device 30; the electronic device 30 does not require special design (e.g., no openings). When using the electronic device 30, only the protective shell 10 needs to be fitted onto it, which is very beneficial for the widespread adoption and promotion of the protective shell 10.

[0070] Please see Figure 6 and Figure 7 , Figure 7 (a) is one implementation method. Figure 6 (a) shows a cross-sectional view of the protective shell along line II. Figure 7 (b) in the text represents another implementation method. Figure 6 The protective shell shown in (a) is a cross-sectional view along line II. The first coupling member 120 includes a first sub-coupling member 121 and a second sub-coupling member 122. The second sub-coupling member 122 is spaced apart from the first sub-coupling member 121. When the protective shell 10 is in the second state: the first sub-coupling member 121 is stacked and spaced apart from the first coupling radiator 140, and the second sub-coupling member 122 is stacked and spaced apart from the first coupling radiator 140. It can be understood that, for ease of illustration of the positions of the protective shell 10 and the first radiator 311, the position of the first radiator 311 when the protective shell 10 is in the second state is shown in the figure.

[0071] The first sub-coupler 121 may be, but is not limited to, a metal sheet or a conductive coating, etc., and the second sub-coupler 122 may be, but is not limited to, a metal sheet, a conductive coating, a flexible printed circuit board (FPC) conductive layer, or a laser direct forming (LDS) conductive layer, etc. The metal sheet may be, but is not limited to, a steel sheet or an aluminum sheet, etc. The material of the first sub-coupler 121 may be the same as or different from that of the second sub-coupler 122, and this application does not limit this.

[0072] When the protective shell 10 is in the second state, the first sub-coupler 121 is stacked and spaced apart from the first coupling radiator 140, thus ensuring that the first sub-coupler 121 is coupled to the first coupling radiator 140 when the protective shell 10 is in the second state. When the protective shell 10 is in the second state, the second sub-coupler 122 is stacked and spaced apart from the first coupling radiator 140, thus ensuring that the second sub-coupler 122 is coupled to the first coupling radiator 140 when the protective shell 10 is in the second state.

[0073] The protective shell 10 provided in this application embodiment includes a first sub-coupler 120 comprising a first sub-coupler 121 and a second sub-coupler 122. When the protective shell 10 is in a second state: the first sub-coupler 121 is stacked and spaced apart from the first coupling radiator 140, and the second sub-coupler 122 is stacked and spaced apart from the first coupling radiator 140; therefore, when the protective shell 10 is in the second state, the first movable member 130 is folded with the shell base 110, and the first coupling radiator 140 is coupled with the first sub-coupler 121 and the second sub-coupler 122 in the first coupling member 120. The first coupling radiator 140, the first sub-coupler 121, and the second sub-coupler 122 are used together to be excited by the first radiator 311 to support a first frequency band, which is different from the first target frequency band. Therefore, when the protective shell 10 is in the second state, the distance between the first coupling radiator 140 and the first radiator 311 in the electronic device 30 is relatively close, and the clearance environment of the first coupling radiator 140 is relatively harsh. The first coupling radiator 140 and the first coupling member 120 jointly support the first frequency band. Therefore, when the protective shell 10 is in the second state, the adverse effects of the first coupling radiator 140 on the first target frequency band supported by the first radiator 311 of the electronic device 30 can be reduced or even avoided. This ensures that when the protective shell 10 is in the second state, the electronic device component 1 on which the protective shell 10 is used still has good performance in the first target frequency band. In addition, the first coupling member 120 includes a first sub-coupling member 121 and a second sub-coupling member 122. The structure of the first coupling member 120 is simple and easy to implement.

[0074] The protective shell 10 provided in this application embodiment, when the protective shell 10 is in the second state, the first coupling radiator 140 is coupled with the first sub-coupler 121 and the second sub-coupler 122 respectively to form a new coupling radiator. The operating frequency band of the new coupling radiator is a first frequency band, which is different from the first target frequency band, thereby reducing the impact on the performance of the first target frequency band.

[0075] When the protective shell 10 is applied to the electronic device assembly 1, when the protective shell 10 is in the first state, the first sub-coupler 121 and the second sub-coupler 122 are relatively far away from the first radiator 311 of the first antenna 310 in the electronic device 30, and will not have a negative impact on the performance of the first target frequency band supported by the first radiator 311.

[0076] Please refer to the following: Figure 6 and Figure 7 ,exist Figure 6 and Figure 7In this illustration, the first sub-coupler 121 and the second sub-coupler 122 are arranged on the same layer as an example. It should be understood that this should not be construed as limiting the embodiments of this application. When the first sub-coupler 121 and the second sub-coupler 122 are arranged on the same layer, along... Figure 6 From the cross-sectional view along line II in (a) of the diagram, the first sub-coupler 121 is obscured by the second sub-coupler 122. The stacking relationship between the first sub-coupler 121 and the first coupled radiator 140 can be seen in [reference needed]. Figure 7 The layering relationship between the second sub-coupler 122 and the first coupled radiator 140 is shown in the diagram. Figure 7 In the cross-sectional view shown in (a), the example of the first coupling radiator 140 being embedded in the first movable member 130 is illustrated. It should be understood that this should not be construed as a limitation on the relationship between the first coupling radiator 140 and the first movable member 130 in the protective shell 10 provided in this application, as long as the first coupling radiator 140 is supported by the first movable member 130. For example, the first coupling radiator 140 may also be disposed on the surface of the first movable member 130 near the first coupling member 120, or the first coupling radiator 140 may also be disposed on the surface of the first movable member 130 away from the first coupling member 120. Figure 7 In (a) of the diagram, when the protective shell 10 is in the second state, the first coupling radiator 140 is disposed adjacent to the outer surface 111b relative to the first coupling member 120, and the first coupling member 120 is disposed adjacent to the inner surface 111a relative to the first coupling radiator 140. It should be understood that this should not be construed as a limitation on the relative positional relationship between the first coupling member 120 and the first coupling radiator 140. In other embodiments, the first coupling member 120 may also be disposed adjacent to the outer surface 111b relative to the first coupling radiator 140. This is only required when the protective shell 10 is in the second state: the first sub-coupling member 121 is stacked and spaced apart from the first coupling radiator 140, and the second sub-coupling member 122 is stacked and spaced apart from the first coupling radiator 140. It should be noted that "stacked" in this paragraph includes stacking on the third direction D3. Furthermore, in... Figure 7 In (a), the first receiving cavity 110d is located between the inner surface 111a and the outer surface 111b. The first opening 110f of the first receiving cavity 110d is located at the housing frame portion 112.

[0077] exist Figure 7In (b) of this application, the example of the first coupling radiator 140 being embedded in the first movable member 130 is used for illustration. It should be understood that this should not be construed as a limitation on the relationship between the first coupling radiator 140 and the first movable member 130 in the protective shell 10 provided in this application, as long as the first coupling radiator 140 is supported by the first movable member 130. Figure 7 In (b) of the diagram, when the protective shell 10 is in the second state, the first coupling member 120 is disposed adjacent to the inner surface 111a relative to the first coupling radiator 140. This should not be construed as limiting the relative positional relationship between the first coupling member 120 and the first coupling radiator 140. In other embodiments, the first coupling member 120 may also be disposed adjacent to the outer surface 111b relative to the first coupling radiator 140. This is as long as the following conditions are met when the protective shell 10 is in the second state: the first sub-coupling member 121 is stacked and spaced apart from the first coupling radiator 140, and the second sub-coupling member 122 is stacked and spaced apart from the first coupling radiator 140. It should be noted that "stacked" in this paragraph includes stacking on the third direction D3. Furthermore, in... Figure 7 In (b), the first receiving cavity 110d is a groove located on the outer surface 111b. The first opening 110f of the first receiving cavity 110d is located on the housing frame portion 112.

[0078] Please continue reading. Figure 6 and Figure 7 The first coupling radiator 140 has a first coupling end 141 and a second coupling end 142. The first coupling end 141 and the second coupling end 142 are respectively the two ends of the first coupling radiator 140 arranged opposite to each other along its length. When the protective shell 10 is in the second state: the first sub-coupling member 121 is stacked and spaced apart from the first coupling end 141, and the second sub-coupling member 122 is stacked and spaced apart from the second coupling end 142.

[0079] In the protective shell 10 provided in this embodiment, the first coupling radiator 140 has a first coupling end 141 and a second coupling end 142 disposed opposite to each other along the length direction of the first coupling radiator 140. The first sub-coupling member 121 is stacked and spaced apart from the first coupling end 141, and the second sub-coupling member 122 is stacked and spaced apart from the second coupling end 142. Therefore, the first sub-coupling member 121 is coupled to the first coupling radiator 140 through the first coupling end 141, and the second sub-coupling member 122 is coupled to the first coupling radiator 140 through the second coupling end 142. Thus, the size of the first coupling radiator 140 can be adjusted. Given a fixed size, a fixed size for the first sub-coupler 121, and a fixed size for the second sub-coupler 122, the overall electrical length of the first coupling radiator 140 and the first coupling 120 is relatively long, resulting in a larger deviation between the first frequency band and the first target frequency band. Consequently, when the protective shell 10 is in the second state, the adverse effects of the first coupling radiator 140 on the performance of the first target frequency band supported by the first radiator 311 are reduced or even eliminated. Therefore, when the protective shell 10 is in the second state and is applied to the electronic device 30, the electronic device 30 still has good performance in the first target frequency band.

[0080] Please continue reading. Figure 6 and Figure 7 When the protective shell 10 is in the second state: the coupling area between the first sub-coupler 121 and the first coupling radiator 140 is the first coupling area S. 10 Furthermore, a first gap d1 exists between the first sub-coupler 121 and the first coupled radiator 140. When the protective shell 10 is in the second state: the coupling area between the second sub-coupler 122 and the first coupled radiator 140 is the second coupling area S. 20 Furthermore, a second gap d2 exists between the second sub-coupler 122 and the first coupling radiator 140. The sum S0 of the first coupling area and the second coupling area satisfies: 40 mm. 2 ≤S0≤60mm 2 , 0.2mm≤d1≤0.4mm, 0.2mm≤d2≤0.4mm.

[0081] The first coupling area S 10 With the second coupling area S 20 The sum S0 can be, but is not limited to, 40mm. 2 or 45mm 2 or 50mm 2 or 55mm 2 or 60mm2 The first gap d1 can be, but is not limited to, 0.2 mm, 0.3 mm, or 0.4 mm. The second gap d2 can be, but is not limited to, 0.2 mm, 0.3 mm, or 0.4 mm. The first coupling area S 10 With the second coupling area S 20 They can be equal or unequal. The first gap d1 can be equal to or unequal to the second gap d2.

[0082] The protective shell 10 provided in this embodiment of the application has a first coupling area and a second coupling area sum S0 satisfying 40mm. 2 ≤S0≤60mm 2 The dimensions 0.2mm≤d1≤0.4mm and 0.2mm≤d2≤0.4mm allow for better coupling between the first sub-coupler 121 and the first coupling radiator 140, and also better coupling between the second sub-coupler 122 and the first coupling radiator 140. Therefore, given a fixed size for the first coupling radiator 140, the first sub-coupler 121, and the second sub-coupler 122, the overall electrical length of the first coupling radiator 140 and the first coupling member 120 is relatively long, resulting in a larger deviation between the first frequency band and the first target frequency band. Consequently, when the protective shell 10 is in the second state, the adverse effects of the first coupling radiator 140 on the performance of the first target frequency band supported by the first radiator 311 are reduced or even eliminated. Thus, when the protective shell 10 is in the second state and is applied to the electronic device 30, the electronic device 30 still exhibits good performance in the first target frequency band.

[0083] In this embodiment, the first coupling area S 10 With the second coupling area S 20 Taking the example of equality, and illustrating the case where the first gap d1 is equal to the second gap d2, it should be understood that this should not be construed as a limitation on the protective shell 10 provided in the embodiments of this application. When the first coupling area S 10 With the second coupling area S 20 When the first gap d1 and the second gap d2 are equal, the coupling effect between the first sub-coupler 121 and the first coupling radiator 140 is more consistent with the coupling effect between the second sub-coupler 122 and the first coupling radiator 140.

[0084] Please see Figure 8 , Figure 8 for Figure 1The diagram shows detailed markings of the protective shell. The shell base 110 has a first side 110a, a second side 110b, and a third side 110c that are bent and connected in sequence. The length of the first side 110a is less than the length of the second side 110b, and the length of the third side 110c is less than the length of the second side 110b. The first movable member 130 is positioned corresponding to the second side 110b.

[0085] In this embodiment, the first side 110a and the third side 110c are both short sides of the shell base 110, and the second side 110b is the long side of the shell base 110.

[0086] When the protective shell 10 is applied to the electronic device 30, the first side 110a and the third side 110c are both set to correspond to the short side of the electronic device 30, and the second side 110b is set to correspond to the long side of the electronic device 30.

[0087] The first movable component 130 is positioned corresponding to the second side 110b. Thus, when the electronic device 30, on which the protective case 10 is applied, is in landscape mode and held by the user, the user's hands are less likely to obstruct the first movable component 130, making it easier for the first movable component 130 to switch from the second state to the first state. This allows the electronic device component 1 to have better antenna performance in the first target frequency band.

[0088] In this embodiment, when the protective case 10 is applied to the electronic device 30, the first side 110a of the protective case 10 corresponds to the top edge of the electronic device 30 in portrait mode, the second side 110b of the protective case 10 corresponds to the long side (also called the side edge) of the electronic device 30 in portrait mode, and the third side 110c of the protective case 10 corresponds to the bottom edge of the electronic device 30 in portrait mode. This ensures that when the electronic device 30 is in landscape mode and held by the user, the user's hands are less likely to obstruct the first movable component 130, thus facilitating the switching of the first movable component 130 from the second state to the first state. This allows the electronic device component 1 to have better antenna performance in the first target frequency band.

[0089] Please see Figure 8 and Figure 9 , Figure 9 for Figure 8The diagram shows a detailed illustration of an electronic device component with the protective case in landscape mode and held by both hands. The first movable member 130 has a first side line 130a and a second side line 130b arranged opposite each other. The first side line 130a is adjacent to the first side 110a relative to the second side line 130b, and the second side line 130b is adjacent to the third side 110c relative to the first side line 130a. When the protective case 10 is in the first state: the distance D1 between the first side line 130a and the first side 110a satisfies: 40mm ≤ D1 ≤ 60mm, and the distance D2 between the second side line 130b and the third side 110c satisfies: 40mm ≤ D2 ≤ 60mm.

[0090] exist Figure 9 In the diagram, the first side 110a is the right side of the protective shell 10, and the third side 110c is the left side of the protective shell 10; the first side line 130a is the side line (also called the side) located to the right of the first movable member 130, and the second side line 130b is the side line (also called the side) located to the left of the first movable member 130.

[0091] When the protective shell 10 is in the first state, the distance D1 between the first edge 130a and the first edge 110a can be, but is not limited to, 40mm, 45mm, 50mm, 55mm, or 60mm. When the protective shell 10 is in the first state, the distance D2 between the second edge 130b and the third edge 110c can be, but is not limited to, 40mm, 45mm, 50mm, 55mm, or 60mm. D1 can be equal to D2, or D1 can be unequal to D2; this is not limited in this embodiment.

[0092] When the protective shell 10 is in the first state: the distance D1 between the first edge 130a and the first edge 110a satisfies: 40mm ≤ D1 ≤ 60mm, and the distance D2 between the second edge 130b and the third edge 110c satisfies: 40mm ≤ D2 ≤ 60mm. This ensures that when the protective shell 10 is applied to the electronic device 30, and the electronic device component 1 is in a landscape position and held by the user with both hands, it is less likely to obstruct the first movable component 130, and less likely to obstruct the first coupling radiator 140 of the first movable component 130. Therefore, when the protective shell 10 is in the first state, the electronic device component 1 has better performance in the first target frequency band.

[0093] Please see Figure 6 , Figure 7 and Figure 10 , Figure 10 for Figure 6 The diagram (a) shows the length and width of the first coupled radiator in the protective shell. For clarity, the dimensions of the first coupled radiator are shown below. Figure 10 Compared to Figure 6 Some components are omitted. The length L1 of the first coupling radiator 140 satisfies: 3λ1 / 8 ≤ L1 ≤ 5λ1 / 8, where λ1 is the wavelength corresponding to the centerline frequency of the first target frequency band. The width W1 of the first coupling radiator 140 satisfies: λ1 / 16 ≤ W1 ≤ 3λ1 / 16. The thickness Da of the first coupling radiator 140 satisfies: 0.15mm ≤ Da ≤ 0.5mm.

[0094] The length L1 of the first coupled radiator 140 satisfies: 3λ1 / 8 ≤ L1 ≤ 5λ1 / 8, that is, the length L1 of the first coupled radiator 140 satisfies: [(λ1 / 2) - (λ1 / 8)] ≤ L1 ≤ [(λ1 / 2) + (λ1 / 8)]. The length L1 of the first coupled radiator 140 can be, but is not limited to, 3λ1 / 8, λ1 / 2, or 5λ1 / 8.

[0095] The length L1 of the first coupled radiator 140 satisfies: 3λ1 / 8 ≤ L1 ≤ 5λ1 / 8. Therefore, when the protective shell 10 is in the first state, the first coupled radiator 140 can be well coupled with the first radiator 311 and excited to activate the half-wavelength mode of the first coupled radiator 140 to support the first target frequency band. Therefore, when the protective shell 10 is in the first state, the performance of the electronic device component 1 supporting the first target frequency band is better than the performance of the electronic device 30 supporting the first target frequency band.

[0096] The width W1 of the first coupling radiator 140 satisfies: [(λ1 / 8)-(λ1 / 16)]≤W1≤[(λ1 / 8)+(λ1 / 16)], which allows the first coupling radiator 140 and the first radiator 311 to have a better coupling effect.

[0097] The thickness Da of the first coupling radiator 140 can be, but is not limited to, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, or 0.5 mm. The thickness Da of the first coupling radiator 140 satisfies: 0.15 mm ≤ Da ≤ 0.5 mm. This allows the first coupling radiator 140 to be easily and conveniently manufactured, meeting the coupling requirements between the first coupling radiator 140 and the first radiator 311 when the protective shell 10 is in the first state, and the coupling requirements between the first coupling radiator 140 and the first coupling member 120 when the protective shell 10 is in the second state. Furthermore, it results in a smaller thickness of the protective shell 10 in the second state, making the protective shell 10 relatively thin and light.

[0098] When the protective shell 10 is in the first state: the first coupled radiator 140 is excited to generate a half-wavelength mode to support the first target frequency band.

[0099] It should be noted that the “wavelength” in the first target frequency band, which is excited to generate a half-wavelength mode to support the first target frequency band, refers to the wavelength corresponding to the center frequency (also known as the center frequency point) of the first target frequency band.

[0100] The first coupled radiator 140 is excited to generate a half-wavelength mode to support the first target frequency band. Therefore, the length of the first coupled radiator 140 can be half the wavelength of the first target frequency band, or approximately half the wavelength of the first target frequency band.

[0101] In this embodiment, the first coupled radiator 140 is excited to generate a half-wavelength mode to support the first target frequency band. Therefore, the first coupled radiator 140 is excited by the first radiator 311 to support the first target frequency band. Thus, when the protective case 10 is applied to the electronic device component 1 to protect the electronic device 30, the electronic device component 1 to which the protective case 10 is applied can also have better performance in the first target frequency band.

[0102] Please see Figure 1 , Figure 2 , Figure 6 and Figure 7 The housing base 110 has a first receiving cavity 110d. When the protective shell 10 is in the first state, the first movable member 130 extends at least partially out of the first receiving cavity 110d. When the protective shell 10 is in the second state, the first movable member 130 is received in the first receiving cavity 110d.

[0103] The protective shell 10 provided in this embodiment has a shell base 110 having a first receiving cavity 110d. The first movable member 130 is received within the first receiving cavity 110d, and at least a portion of the first movable member 130 can extend out from the first receiving cavity 110d. When the protective shell 10 is in the second state, the first movable member 130 is received within the first receiving cavity 110d, and the first coupled radiator 140 supported on the first movable member 130 is also received within the first receiving cavity 110d, thereby protecting the first coupled radiator 140 and reducing or even avoiding the risk of damage to the first coupled radiator 140.

[0104] Please refer to the following: Figure 11 , Figure 12 and Figure 13 , Figure 11 A schematic diagram showing the protective shell in a first state according to another embodiment of this application; Figure 12 for Figure 11 The diagram shown illustrates the protective shell in its second state. Figure 13 for Figure 11 The diagram shows the protective shell in an intermediate state. In this embodiment, the first movable member 130 and the shell base 110 can be connected by, but not limited to, a hinge, or movably connected by a pivot. In one embodiment, the first movable member 130 and the shell base 110 can be adjusted arbitrarily between 0° and 180°; or, the first movable member 130 and the shell base 110 can be adjusted between multiple different angles between 0° and 180°. When the protective shell 10 is in the first state, the angle between the first movable member 130 and the shell base 110 can be considered as 180°; when the protective shell 10 is in the second state, the angle between the first movable member 130 and the shell base 110 can be considered as 0°. Please refer to... Figure 13 The protective shell 10 also has an intermediate state between the first state and the second state. When the protective shell 10 is in the intermediate state, the first movable member 130 and the shell base 110 form a preset angle, wherein the preset angle is greater than 0° and less than 180°. In one case, when the protective shell 10 is in the intermediate state, and when the protective shell 10 is applied to the electronic device 30, the first movable member 130 of the protective shell 10, in conjunction with the shell base 110, can also serve as a support for the electronic device 30. For example, the preset angle can be, but is not limited to, 30°, 35°, or 45°, etc.

[0105] Please see Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 , Figure 14 A schematic diagram of the protective shell provided in a first state according to another embodiment of this application; Figure 15 for Figure 14 The diagram shown illustrates the protective shell in its second state. Figure 16 for Figure 14 The diagram shown illustrates the application of a protective casing to electronic device components. Figure 17 for Figure 16 An exploded view of the electronic device shown; Figure 18 This is a schematic diagram of a second antenna in an electronic device according to one embodiment. In this embodiment, the electronic device 30 further includes a second antenna 320, which includes a second radiator 321 for supporting a second target frequency band. The protective housing 10 also includes a second movable member 150 and a second coupling radiator 160. The second movable member 150 is movably connected to the housing base 110. The second coupling radiator 160 is supported by the second movable member 150. When the protective housing 10 is in the first state, the second movable member 150 is at least partially deployed relative to the housing base 110, and the second coupling radiator 160 is coupled to and activated with the second radiator 321 of the second antenna 320 of the electronic device 30 to support the second target frequency band.

[0106] In this embodiment, the protective shell 10 further includes a second movable member 150 and a second coupling radiator 160, which are combined with the protective shell 10 provided in any of the preceding embodiments. The schematic diagram of the embodiment of this application is illustrated by taking the protective shell 10 further including a second movable member 150 and a second coupling radiator 160, which are combined with the protective shell 10 provided in the preceding embodiment as an example. It should be understood that this should not be construed as a limitation on the protective shell 10 provided in the embodiment of this application.

[0107] Figure 18 The electronic device 30 includes a second antenna 320, which includes a second radiator 321 and a second feed S2. The second feed S2 is electrically connected to the second radiator 321 to excite the second radiator 321 to support a second target frequency band.

[0108] In the schematic diagram of this embodiment, the second antenna 320 is used as an IFA antenna, and the second radiator 321 is used as a frame antenna radiator for illustration. It should be understood that this should not be construed as a limitation on the second antenna 320 of the electronic device 30. As long as the second antenna 320 can support the second target frequency band, it is acceptable. Specifically, the second radiator 321 includes a second free end 3211 (also called an end point), a second ground end 3212, and a second feed point P2 located between the second free end 3211 and the second ground end 3212. The second ground end 3212 is grounded. The second feed source S2 is electrically connected to the second feed point P2 to excite the second radiator 321 to support the second target frequency band.

[0109] In this embodiment, the second target frequency band is described as a low frequency band. It should be understood that this should not be construed as a limitation on the protective shell 10 and the electronic device component 1 on which the protective shell 10 is applied in the embodiments of this application.

[0110] The second movable member 150 may be movably connected to the housing base 110 in a manner that includes, but is not limited to, a hinge connection, a pivot connection, a rebound mechanism, a turntable connection, or a pull-out connection. This application does not limit the manner in which the second movable member 150 is movably connected to the housing base 110. The manner in which the second movable member 150 is movably connected to the housing base 110 may be the same as or different from the manner in which the second movable member 150 is movably connected to the housing base 110; this application does not limit this.

[0111] The second coupling radiator 160 can be supported on the second movable member 150 in various ways, including but not limited to: the second coupling radiator 160 being embedded within the second movable member 150; the second coupling radiator 160 being disposed on the surface of the second movable member 150; or the second coupling radiator 160 being connected to the second movable member 150 with a gap between them; this application does not limit the manner in which the second coupling radiator 160 is supported on the second movable member 150. Since the second coupling radiator 160 is supported on the second movable member 150, the second coupling radiator 160 can move along with the movement of the second movable member 150.

[0112] When the protective housing 10 is in the second state, the second movable member 150 is deployed at least relative to the housing base 110. Since the second coupling radiator 160 is supported by the second movable member 150, the second coupling radiator 160 is also deployed relative to the housing base 110 when the protective housing 10 is in the second state. When the protective housing 10 is in the second state, the second coupling radiator 160 is coupled to the second radiator 321 of the second antenna 320 in the electronic device 30, and the second coupling radiator 160 is excited by the second radiator 321 to support the second target frequency band. Therefore, when the protective housing 10 is in the second state, the performance of the electronic device assembly 1 supporting the second target frequency band is superior to the performance of the second target frequency band supported by the electronic device 30. Furthermore, when the protective shell 10 is in the second state, the second movable member 150 is deployed relative to the shell base 110. Since the second coupling radiator 160 is supported by the second movable member 150, the second coupling radiator 160 is also deployed relative to the shell base 110. The distance between the second coupling radiator 160 and other components in the electronic device 30 is relatively far, the second coupling radiator 160 has good clearance, and the second coupling radiator 160 supports better performance in the second target frequency band. Therefore, it can be seen that the protective shell 10 provided in this embodiment, when the protective shell 10 is in the second state, provides that the electronic device component 1 on which the protective shell 10 is applied has good performance in the second target frequency band.

[0113] Further, please refer to Figure 19 and Figure 20 , Figure 19 (a) in the middle is Figure 15 A schematic diagram of the protective casing from one perspective; Figure 19 (b) is a schematic diagram of a protective shell provided in another embodiment from one perspective; Figure 20 (a) is one implementation method. Figure 19 (a) shows a cross-sectional view of the protective shell along line II-II; Figure 20 (b) is one implementation method. Figure 19The protective shell 10 is shown in (a) as a cross-sectional view along line II-II. The protective shell 10 also includes a second coupling member 170, which is supported by the shell base 110. When the protective shell 10 is in the second state, the second movable member 150 is folded to the shell base 110, and the second coupled radiator 160 is coupled to the second coupling member 170. The second coupled radiator 160 and the second coupling member 170 are used together to be excited by the second radiator 321 to support a second frequency band, wherein the second frequency band is different from the second target frequency band. Understandably, for ease of illustration of the positions of the protective shell 10, the first radiator 311, and the second radiator 321, the positions of the first radiator 311 and the second radiator 321 when the protective shell 10 is in the second state are shown in the figure.

[0114] When the protective shell 10 is in the second state, the second movable member 150 is folded relative to the shell base 110. Since the second coupled radiator 160 is supported by the second movable member 150, the first coupled radiator 140 is also folded relative to the shell base 110 when the protective shell 10 is in the second state. When the protective shell 10 is in the second state, the second coupled radiator 160 is coupled with the second coupled member 170. The second coupled radiator 160 and the second coupled member 170 are used together to be excited by the second radiator 321 to support the second frequency band. The second frequency band is different from the second target frequency band. Therefore, when the protective shell 10 is in the second state, the distance between the second coupled radiator 160 and the second radiator 321 in the electronic device 30 is relatively close, and the clearance environment of the second coupled radiator 160 is relatively harsh. If the second coupled radiator 160 couples with the first coupled radiator 140 to generate the second target frequency band, the second target frequency band has an efficiency dip, resulting in poor performance of the second target frequency band. In the protective housing 10 provided in this application embodiment, when the protective housing 10 is in the second state, the second coupling radiator 160 is coupled to the second coupling member 170, and the second coupling radiator 160 and the second coupling member 170 jointly support the second frequency band. The second frequency band is different from the second target frequency band. Therefore, when the protective housing 10 is in the second state, the adverse effects of the second coupling radiator 160 on the second target frequency band supported by the second radiator 321 of the electronic device 30 can be reduced or even avoided. This ensures that when the protective housing 10 is in the second state, the electronic device component 1 on which the protective housing 10 is applied still has good performance in the second target frequency band.

[0115] In one embodiment, the electrical length of the second coupling radiator 160 matches the electrical length required for the second target frequency band. Therefore, when the protective shell 10 is in the first state, the second coupling radiator 160 is coupled to the second radiator 321, and the second coupling radiator 160 is excited by the second radiator 321 to support the second target frequency band. When the protective shell 10 is in the second state, the second coupling radiator 160 is coupled to the second coupling member 170. The sum of the electrical lengths of the second coupling radiator 160 and the second coupling member 170 is mismatched with the electrical length required for the second target frequency band. However, the sum of the electrical lengths of the second coupling radiator 160 and the second coupling member 170 matches the electrical length required for the second frequency band. Therefore, when the protective shell 10 is in the second state, the second coupling radiator 160 and the second coupling member 170 jointly support the second frequency band. Therefore, when the protective case 10 is in the second state, the adverse effects of the second coupling radiator 160 on the second target frequency band supported by the second radiator 321 of the electronic device 30 can be reduced or even avoided, so that when the protective case 10 is in the second state, the electronic device component 1 on which the protective case 10 is applied still has good performance in the second target frequency band.

[0116] Please continue reading. Figure 19 and Figure 20 The second coupling member 170 includes a third sub-coupling member 171 and a fourth sub-coupling member 172. The fourth sub-coupling member 172 is spaced apart from the third sub-coupling member 171. Specifically, when the protective shell 10 is in the second state: the third sub-coupling member 171 is stacked and spaced apart from the second coupling radiator 160, and the fourth sub-coupling member 172 is stacked and spaced apart from the second coupling radiator 160.

[0117] The third sub-coupler 171 can be, but is not limited to, a metal sheet or a conductive coating, etc., and the fourth sub-coupler 172 can be, but is not limited to, a metal sheet, a conductive coating, a flexible printed circuit board (FPC) conductive layer, or a laser direct forming (LDS) conductive layer, etc. The metal sheet can be, but is not limited to, a steel sheet or an aluminum sheet, etc. The material of the third sub-coupler 171 can be the same as or different from that of the fourth sub-coupler 172, and this application does not limit this.

[0118] When the protective shell 10 is in the second state, the third sub-coupler 171 is stacked and spaced apart from the second coupling radiator 160, thus enabling coupling between the third sub-coupler 171 and the second coupling radiator 160 when the protective shell 10 is in the second state. When the protective shell 10 is in the second state, the fourth sub-coupler 172 is stacked and spaced apart from the second coupling radiator 160, thus enabling coupling between the fourth sub-coupler 172 and the second coupling radiator 160 when the protective shell 10 is in the second state.

[0119] The protective shell 10 provided in this application embodiment includes a second coupling member 170 comprising a third sub-coupling member 171 and a fourth sub-coupling member 172. When the protective shell 10 is in a second state: the third sub-coupling member 171 is stacked and spaced apart from the second coupling radiator 160, and the fourth sub-coupling member 172 is stacked and spaced apart from the second coupling radiator 160. Therefore, when the protective shell 10 is in the second state, the second movable member 150 is folded with the shell base 110, and the second coupling radiator 160 is coupled with the third sub-coupling member 171 and the fourth sub-coupling member 172 in the second coupling member 170. The second coupling radiator 160, the third sub-coupling member 171, and the fourth sub-coupling member 172 are used together to be excited by the second radiator 321 to support a second frequency band, which is different from the second target frequency band. Therefore, when the protective shell 10 is in the second state, the distance between the second coupling radiator 160 and the second radiator 321 in the electronic device 30 is relatively close, and the clearance environment of the second coupling radiator 160 is relatively harsh. The second coupling radiator 160 and the second coupling member 170 jointly support the second frequency band. Therefore, when the protective shell 10 is in the second state, the adverse effects of the second coupling radiator 160 on the second target frequency band supported by the second radiator 321 of the electronic device 30 can be reduced or even avoided. This ensures that when the protective shell 10 is in the second state, the electronic device component 1 on which the protective shell 10 is used still has good performance in the second target frequency band. In addition, the second coupling member 170 includes a third sub-coupling member 171 and a fourth sub-coupling member 172, and the structure of the second coupling member 170 is simple and easy to implement.

[0120] exist Figure 20In the cross-sectional view shown in (a), the second coupling radiator 160 is embedded within the second movable member 150 as an example. It should be understood that this should not be construed as a limitation on the relationship between the second coupling radiator 160 and the second movable member 150 in the protective shell 10 provided in this application embodiment, as long as the second coupling radiator 160 is supported by the second movable member 150. For example, the second coupling radiator 160 may also be disposed on the surface of the second movable member 150 near the second coupling member 170, or the second coupling radiator 160 may also be disposed on the surface of the second movable member 150 away from the second coupling member 170. Figure 20 In (a) of the diagram, when the protective shell 10 is in the second state, the second coupling radiator 160 is away from the inner surface 111a relative to the second coupling member 170. It is understood that in other embodiments, when the protective shell 10 is in the second state, the second coupling radiator 160 is closer to the inner surface 111a relative to the second coupling member 170. This is provided that when the protective shell 10 is in the second state: the third sub-coupling member 171 is stacked and spaced apart from the second coupling radiator 160, and the fourth sub-coupling member 172 is stacked and spaced apart from the second coupling radiator 160. It should be noted that "stacked" in this paragraph includes stacking on the third direction D3. Furthermore, in... Figure 20 In (a), the second receiving cavity 110e is located between the inner surface 111a and the outer surface 111b. The second opening 110g of the second receiving cavity 110e is located at the housing frame portion 112.

[0121] exist Figure 20 In (b) of this application, the second coupling radiator 160 is embedded in the second movable member 150 as an example. It should be understood that this should not be construed as a limitation on the relationship between the second coupling radiator 160 and the second movable member 150 in the protective shell 10 provided in this application. It is sufficient that the second coupling radiator 160 is supported by the second movable member 150.

[0122] exist Figure 20In (b) of the diagram, when the protective shell 10 is in the second state, the second coupling member 170 is disposed adjacent to the inner surface 111a relative to the second coupling radiator 160. This should not be construed as a limitation on the relative positional relationship between the second coupling member 170 and the second coupling radiator 160. In other embodiments, the second coupling member 170 may also be disposed adjacent to the outer surface 111b relative to the second coupling radiator 160. This is provided that when the protective shell 10 is in the second state: the third sub-coupling member 171 is stacked and spaced apart from the second coupling radiator 160, and the fourth sub-coupling member 172 is stacked and spaced apart from the second coupling radiator 160. It should be noted that "stacked" in this paragraph includes stacking on the third direction D3. Furthermore, in... Figure 20 In (b), the second receiving cavity 110e is a groove located on the outer surface 111b. The second opening 110g of the second receiving cavity 110e is located on the housing frame portion 112.

[0123] Please refer to the following: Figures 16 to 20 , Figure 21 and Figure 22 , Figure 21 A schematic diagram of the protective shell provided in one embodiment of this application in a third state; Figure 22This is a schematic diagram of a protective shell provided in an embodiment of the present application in a fourth state. The second movable member 150 and the first movable member 130 are independent of each other. In addition to the first and second states, the protective shell 10 also has a third and a fourth state. In the schematic diagram of this embodiment, the protective shell 10 is illustrated as an example of its application in an electronic device assembly 1. It should be understood that this should not be construed as a limitation on the protective shell 10 provided in the embodiment of the present application. When the protective shell 10 is in the third state: the first movable member 130 is at least partially unfolded relative to the shell base 110, and the first coupling radiator 140 is used to couple with the first radiator 311 and is excited to support a first target frequency band; the second movable member 150 is folded with the shell base 110; the second coupling radiator 160 is coupled with the second coupling member 170; the second coupling radiator 160 and the second coupling member 170 are jointly used to be excited by the second radiator 321 to support a second frequency band, wherein the second frequency band is different from the second target frequency band. When the protective shell 10 is in the fourth state: the first movable member 130 is folded with the shell base 110, the first coupling radiator 140 is coupled with the first coupling member 120, the first coupling radiator 140 and the first coupling member 120 are used together to be excited by the first radiator 311 to support the first frequency band, wherein the first frequency band is different from the first target frequency band, the second movable member 150 is at least partially unfolded relative to the shell base 110, and the second coupling radiator 160 is used to couple with the second radiator 321 of the second antenna 320 of the electronic device 30 and be excited to support the second target frequency band.

[0124] In this embodiment, the second movable member 150 and the first movable member 130 are independent of each other, and the second movable member 150 and the first movable member 130 can move relative to the housing base 110 respectively. In other words, the second movable member 150 and the first movable member 130 are two independent components. Thus, when the protective shell 10 is used to protect the electronic device 30, the corresponding movable member can be used according to the operating frequency band required by the electronic device 30. For example, when the electronic device 30 needs to operate in the first target frequency band and needs to improve the performance of the first target frequency band, the first movable member 130 can be controlled to at least partially unfold relative to the housing base 110. When the electronic device 30 needs to operate in the second target frequency band and needs to improve the performance of the first target frequency band, the second movable member 150 can be controlled to at least partially unfold relative to the housing base 110.

[0125] It can be seen that the second movable member 150 and the first movable member 130 are independent of each other. The first movable member 130 and the second movable member 150 cooperate with each other to enable the protective shell 10 to have a first state, a second state, a third state and a fourth state, thereby improving the communication needs of the electronic device 30 in the electronic device component 1 to which the protective shell 10 is applied in various scenarios.

[0126] In another embodiment, the second movable member 150 and the first movable member 130 can be an integral structure, and the first movable member 130 and the second movable member 150 move synchronously relative to the housing base 110. In this way, the integration of the protective shell 10 can be improved.

[0127] In one implementation, please refer to Figures 14 to 15 The second movable member 150 and the first movable member 130 are both disposed on the same side of the housing base 110.

[0128] The shell base 110 has a first side 110a, a second side 110b, and a third side 110c that are bent and connected in sequence. The length of the first side 110a is less than the length of the second side 110b, and the length of the third side 110c is less than the length of the second side 110b.

[0129] In this embodiment, both the second movable member 150 and the first movable member 130 are disposed corresponding to the second side 110b of the housing base 110. Since both the first movable member 130 and the second movable member 150 are disposed corresponding to the second side 110b, when the electronic device 30 on which the protective case 10 is applied is in landscape mode and held by the user, the user's hands are less likely to obstruct the first movable member 130 and the second movable member 150, thus facilitating the easy switching of the first movable member 130 from the second state to the first state. This results in the electronic device component 1 having better antenna performance in both the first and second target frequency bands.

[0130] In other embodiments, the second movable member 150 and the first movable member 130 may also be configured corresponding to the first side 110a; or, the second movable member 150 and the first movable member 130 may also be configured corresponding to the third side 110c. As long as the second movable member 150 and the first movable member 130 are configured to correspond to the same side of the housing base 110, it is acceptable.

[0131] When the second movable member 150 and the first movable member 130 are both arranged on the same side of the housing base 110, it is convenient for the user to hold the electronic device assembly 1 and avoid the first movable member 130 and the second movable member 150.

[0132] Please see Figure 23 and Figure 24 , Figure 23 for Figure 14 A schematic diagram showing the details of the second movable component in the second state within the protective casing shown; Figure 24 This is a schematic diagram showing the protective case in its first state, the electronic device components in a landscape orientation, and being held by the user with both hands. The case base 110 has a first side 110a, a second side 110b, and a third side 110c that are sequentially bent and connected. The length of the first side 110a is less than the length of the second side 110b, and the length of the third side 110c is less than the length of the second side 110b. The second movable member 150 has a third side line 150a and a fourth side line 150b that are arranged opposite to each other. The third side line 150a is located closer to the first side 110a than the fourth side line 150b, and the fourth side line 150b is located closer to the third side 110c than the third side line 150a. When the protective shell 10 is in the second state: the distance D3 between the third side line 150a and the first side 110a satisfies: 40mm≤D3≤60mm, and the distance D4 between the fourth side line 150b and the third side 110c satisfies: 40mm≤D4≤60mm.

[0133] exist Figure 24 In the diagram, the first side 110a is the right side of the protective shell 10, and the third side 110c is the left side of the protective shell 10; the first side line 130a is the side line (also called the side) located to the right of the second movable member 150, and the second side line 130b is the side line (also called the side) located to the left of the second movable member 150.

[0134] When the protective shell 10 is in the second state, the distance D3 between the third side line 150a and the first side 110a can be, but is not limited to, 40mm, 45mm, 50mm, 55mm, or 60mm. When the protective shell 10 is in the second state, the distance D4 between the fourth side line 150b and the third side 110c can be, but is not limited to, 40mm, 45mm, 50mm, 55mm, or 60mm. D3 can be equal to D4, or D3 can be unequal to D4; this is not limited in this embodiment.

[0135] When the protective shell 10 is in the second state: the distance D3 between the third side line 150a and the first side 110a satisfies: 40mm ≤ D3 ≤ 60mm, and the distance D4 between the fourth side line 150b and the third side 110c satisfies: 40mm ≤ D4 ≤ 60mm. This ensures that when the protective shell 10 is applied to the electronic device 30, and the electronic device component 1 is in a landscape position and held by the user with both hands, it is less likely to obstruct the second movable component 150, and less likely to obstruct the second coupled radiator 160 of the second movable component 150. Therefore, when the protective shell 10 is in the first state, the electronic device component 1 has better performance in the second target frequency band.

[0136] Please see Figure 14 , Figure 15 , Figure 21 and Figure 22 The housing base 110 has a second receiving cavity 110e. When the protective shell 10 is in the first state, the second movable member 150 extends at least partially out of the second receiving cavity 110e. When the protective shell 10 is in the second state, the second movable member 150 is received in the second receiving cavity 110e.

[0137] The protective shell 10 provided in this embodiment has a shell base 110 having a second receiving cavity 110e. The second movable member 150 is received within the second receiving cavity 110e, and at least a portion of the second movable member 150 can extend out from the second receiving cavity 110e. When the protective shell 10 is in the second state, the second movable member 150 is received within the second receiving cavity 110e, and the second coupled radiator 160 supported on the second movable member 150 is also received within the second receiving cavity 110e, thereby protecting the second coupled radiator 160 and reducing or even avoiding the risk of damage to the second coupled radiator 160.

[0138] In summary, the protective case 10 provided in one embodiment of this application, when applied to the electronic device component 1, and when the electronic device 30 in the electronic device component 1 is in landscape mode and held by the user with both hands, is in the first state. In this state, the first coupling radiator 140 not only enhances the radiation performance of the first target frequency band supported by the first antenna 310, but also improves the signal strength of the first target frequency band received by the electronic device 30, as well as the signal strength of the first target frequency band received by the base station communicating with the electronic device 30. When the electronic device 30 in the electronic device component 1, to which the protective case 10 is applied, is in landscape mode and held by the user for gaming, the protective case 10 in the first state can reduce screen stuttering and signal latency during gaming, improving game smoothness. It is understood that the scenario of the electronic device 30 being in landscape mode and held by the user is not limited to gaming; it can also be used for watching videos or live streams in landscape mode.

[0139] Furthermore, when the electronic device 30 in the electronic device component 1 to which the protective case 10 is applied communicates with other devices (such as base stations) in the first target frequency band, the transmission power of the first target frequency band to be transmitted by the first antenna 310 of the electronic device 30 is low, thereby reducing the power consumption of the electronic device 30 when communicating with other devices using the first target frequency band and increasing the battery life of the electronic device 30.

[0140] It should be noted that the working scenario of the protective shell 10 provided in the preceding embodiments when applied to the electronic device component 1 is illustrated by taking the electronic device 30 of the electronic device component 1 in a game scenario as an example. It should be understood that this should not be construed as a limitation on the embodiments of this application. The electronic device 30 can also be in at least one of the following scenarios: navigation scenario, weak network communication (such as weak network call) scenario, no network communication scenario, and satellite communication scenario.

[0141] The preceding embodiment provides a protective casing 10, and the description takes a mid-to-high frequency band as an example. It should be understood that this should not be construed as a limitation on the embodiments of this application, and the first target frequency band can also be any frequency band. For example, the first target frequency band can also be the WiFi 6E band, or the N79 band, or the GPS L1 band, or the GPS L5 band, etc.

[0142] The preceding embodiment provides a protective casing 10, and the description uses a low-frequency band as an example. It should be understood that this should not be construed as a limitation on the embodiments of this application, and the second target frequency band can also be any frequency band. For example, the second target frequency band can also be the WiFi 6E band, or the N79 band, or the GPS L1 band, or the GPS L5 band, etc.

[0143] In one embodiment, the first target frequency band may be, but is not limited to, one of the following: B1 band, B3 band, N41 band, N78 band, WiFi 2.4G band, and WiFi 5G band. The second target frequency band may be, but is not limited to, one of the following: B5 band, B8 band, and B28 band.

[0144] Please refer to the following: Figures 1 to 4 ,or Figures 14 to 17 As shown in the accompanying drawings, the electronic device assembly 1 includes an electronic device 30 and a protective housing 10 as described in any of the preceding items. The electronic device 30 includes a first antenna 310, which includes a first radiator 311 for supporting a first target frequency band. The protective housing 10 is used to protect the electronic device 30. The protective housing 10 is described above and will not be repeated here.

[0145] Please see Figure 25 , Figure 25 This is a schematic diagram illustrating the coupling distance between two first coupled radiators when the protective shell 10 is in a first state, according to one embodiment. When the protective shell 10 is in the first state, the coupling distance D between the first coupled radiator 140 and the first radiator 311 is... 11 Satisfy: 3mm≤D 11 ≤7mm.

[0146] When the protective shell 10 is in the first state, the coupling distance D between the first coupled radiator 140 and the first radiator 311 is... 11 It can be, but is not limited to, 3mm, 4mm, 5mm, 6mm, or 7mm.

[0147] When the protective shell 10 is in the first state, the distance D between the first coupled radiator 140 and the first radiator 311 is... 11 Satisfy: 3mm≤D 11The thickness is ≤7mm, which allows for better coupling between the first coupling radiator 140 and the first radiator 311 when the protective shell 10 is in the first state. This results in better performance of the first target frequency band signal generated by the coupling energy of the first coupling radiator 140 to the first radiator 311. Thus, the protective shell 10 can have better performance in the first target frequency band when it is in the first state.

[0148] Please refer to further information. Figure 25 When the protective shell 10 is in the first state, the first coupling radiator 140 and the first radiator 311 overlap in the second direction D2 by a dimension D. 22 Satisfy: 0 < D 22 ≤10mm. In this way, on the one hand, the first coupling radiator 140 and the first radiator 311 can have a relatively good coupling effect; on the other hand, when the distance between the first radiator 311 and the first edge 110a is constant and the position of the first coupling radiator 140 and the first movable member 130 is constant, when the protective shell 10 is in the first state, the probability that the first movable member 130 is blocked when the electronic device component 1 on which the protective shell 10 is applied is in a landscape state and is held by the user with both hands is reduced.

[0149] Please continue reading. Figure 25 The shell base 110 has a first side 110a and a second side 110b that are bent and connected. The length of the first side 110a is less than the length of the second side 110b. The first side 110a extends along a first direction D1. The first target frequency band includes the mid-to-high frequency band. When the protective shell 10 is in the first state, the first coupling radiator 140 and the first radiator 311 do not overlap in the first direction D1.

[0150] When the first target frequency band includes the mid-to-high frequency band, when the protective shell 10 is in the first state, the first coupled radiator 140 and the first radiator 311 do not overlap in the first direction D1, thereby making the first coupled radiator 140 have better clearance, and thus making the first target frequency band supported by the first coupled radiator 140 have better performance when the protective shell 10 is in the first state.

[0151] In this embodiment, the extension direction of the second side 110b is taken as the second direction D2, and the thickness direction of the shell base 110 is taken as the third direction D3. In the XYZ coordinate system, the first direction D1 can be the X direction, the second direction D2 can be the Y direction, and the third direction D3 can be the Z direction.

[0152] Please see Figure 26 , Figure 26 This is a schematic diagram illustrating the relative positional relationship between a first coupled radiator and a first radiator when a protective shell is applied to an electronic device assembly according to another embodiment. The shell base 110 has a first side 110a and a second side 110b that are bent and connected together. The length of the first side 110a is less than the length of the second side 110b. The first side 110a extends along a first direction D1. The first target frequency band includes a low-frequency band. When the protective shell 10 is in a first state, the first coupled radiator 140 and the first radiator 311 partially overlap in the first direction D1.

[0153] When the first target frequency band includes a low frequency band, when the protective shell 10 is in the first state, the first coupling radiator 140 and the first radiator 311 partially overlap in the first direction D1, which can make the first coupling radiator 140 and the first radiator 311 have a better coupling effect, so that when the protective shell 10 is in the first state, the first target frequency band supported by the first coupling radiator 140 has better performance.

[0154] Please see Figures 1 to 4 The first coupling radiator 140 and the first radiator 311 are spaced apart in the thickness direction (i.e., third direction D3) of the protective shell 10.

[0155] The first coupling radiator 140 and the first radiator 311 are spaced apart in the thickness direction of the protective shell 10, so that when the protective shell 10 is in the first state or the second state, the first coupling radiator 140 and the first radiator 311 do not come into contact, thereby avoiding the risk of failure caused by the first coupling radiator 140 coming into contact with the first radiator 311.

[0156] Please see Figures 14 to 17 ,and Figure 27 , Figure 27 for Figure 16The diagram shows a partial detail of the protective housing of the electronic device assembly in a first state. The housing base 110 has a first side 110a and a second side 110b that are bent and connected, the length of the first side 110a being less than the length of the second side 110b, and the first side 110a extending along a first direction D1. When the electronic device 30 also includes a second antenna 320, the second antenna 320 including a second radiator 321 for supporting a second target frequency band; and the protective housing 10 also includes a second movable member 150 and a second radiator 321; the second movable member 150 is movably connected to the housing base 110; the second coupled radiator 160 is supported by the second movable member 150; when the protective housing 10 is in the first state, the second movable member 150 is at least partially deployed relative to the housing base 110, and the second coupled radiator 160 is coupled to and excited with the second radiator 321 of the second antenna 320 of the electronic device 30 to support the second target frequency band. The second target frequency band includes a low frequency band. When the protective shell 10 is in the first state, the second coupling radiator 160 and the second radiator 321 partially overlap in the first direction D1.

[0157] In this embodiment, when the first target frequency band includes a mid-to-high frequency band, when the protective shell 10 is in the first state, the first coupled radiator 140 and the first radiator 311 do not overlap in the first direction D1, thereby giving the first coupled radiator 140 better clearance, and thus giving the first target frequency band supported by the first coupled radiator 140 better performance when the protective shell 10 is in the first state.

[0158] When the second target frequency band includes a low frequency band, when the protective shell 10 is in the first state, the second coupling radiator 160 and the second radiator 321 partially overlap in the first direction D1, which can make the second coupling radiator 160 and the second radiator 321 have a better coupling effect, so that when the protective shell 10 is in the first state, the second target frequency band supported by the second coupling radiator 160 has better performance.

[0159] Further, please refer to Figures 14 to 17 The second coupling radiator 160 and the second radiator 321 are spaced apart in the thickness direction (i.e., third direction D3) of the protective shell 10.

[0160] The second coupled radiator 160 and the second radiator 321 are spaced apart in the thickness direction of the protective shell 10, so that when the protective shell 10 is in the first state or the second state, the second coupled radiator 160 and the second radiator 321 do not come into contact, so as to avoid the risk of failure caused by the first coupled radiator coming into contact with the second radiator 321.

[0161] The frequency of the first target frequency band is greater than the frequency of the first frequency band, and the frequency difference between the minimum frequency of the first target frequency band and the maximum frequency of the first frequency band is 100MHz to 500MHz.

[0162] Since the first coupling radiator 140 and the first coupling element 120 jointly support the first frequency band, and the sum of the lengths of the first coupling radiator 140 and the first coupling element 120 is greater than the length of the first coupling radiator 140, the frequency of the first frequency band supported by the first coupling radiator 140 and the first coupling element 120 is lower than the frequency of the first target frequency band that the first coupling radiator 140 can support alone. In other words, the frequency of the first frequency band is less than the frequency of the first target frequency band. The difference between the minimum frequency of the first target frequency band and the maximum frequency of the first frequency band can be, but is not limited to, 100MHz, 150MHz, 200MHz, 250MHz, 300MHz, 350MHz, 400MHz, 450MHz, or 500MHz.

[0163] When the frequency difference between the minimum frequency of the first target frequency band and the maximum frequency of the first frequency band is 100MHz to 500MHz, on the one hand, it allows for a relatively suitable frequency band spacing between the first frequency band and the first target frequency band, reducing or even eliminating the interference of the first frequency band on the first target frequency band; on the other hand, it also allows for a smaller size of the first coupling radiator 140 and the first coupling element 120. In other words, when the frequency difference between the minimum frequency of the first target frequency band and the maximum frequency of the first frequency band is 100MHz to 500MHz, it can simultaneously meet the requirements of miniaturization of the first coupling radiator 140 and the first coupling element 120, and minimal or even no interference from the first frequency band on the first target frequency band.

[0164] The frequency of the second target frequency band is greater than the frequency of the second frequency band, and the frequency difference between the minimum frequency of the second target frequency band and the maximum frequency of the second frequency band is 100MHz to 500MHz.

[0165] Since the second coupling radiator 160 and the second coupling member 170 jointly support the second frequency band, and the sum of the lengths of the second coupling radiator 160 and the second coupling member 170 is greater than the length of the second coupling radiator 160, the frequency of the second frequency band supported by the second coupling radiator 160 and the second coupling member 170 is lower than the frequency of the second target frequency band that the second coupling radiator 160 can support alone. In other words, the frequency of the second frequency band is less than the frequency of the second target frequency band. The difference between the minimum frequency of the second target frequency band and the maximum frequency of the second frequency band can be, but is not limited to, 100MHz, 150MHz, 200MHz, 250MHz, 300MHz, 350MHz, 400MHz, 450MHz, or 500MHz.

[0166] When the frequency difference between the minimum frequency of the second target frequency band and the maximum frequency of the second frequency band is 100MHz to 500MHz, on the one hand, it allows for a relatively suitable frequency band spacing between the second frequency band and the second target frequency band, reducing or even eliminating the interference of the second frequency band on the second target frequency band; on the other hand, it also allows for a smaller size of the second coupling radiator 160 and the second coupling element 170. In other words, when the frequency difference between the minimum frequency of the second target frequency band and the maximum frequency of the second frequency band is 100MHz to 500MHz, it can simultaneously meet the requirements of miniaturization of the second coupling radiator 160 and the second coupling element 170, and minimal or even no interference from the second frequency band on the second target frequency band.

[0167] The above description represents some embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
