[0037] The following will be combined with the attached examples of the present application Figures 1 to 20 , the technical solutions in the embodiments of the present application are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0038] The present application embodiment provides an electronic device and an electronic device control method. The electronic device control method can be applied to an electronic device, that is, the execution subject of the electronic device control method can be the electronic device provided by the present application embodiment. Figure 1 , Figure 2a and Figure 2b , Figure 1 A first structural diagram of an electronic device provided in an embodiment of the present application, Figure 2a and Figure 2b for Figure 1 The electronic device 10 is a schematic diagram of a folding process. Figure 1 , Figure 2a , Figure 2bThe electronic device 10 may be a computing device such as a laptop computer, a computer monitor including an embedded computer, a tablet computer, a cellular phone, a media player, or other handheld or portable electronic device, a smaller device (such as a wristwatch device, a pendant device, a headset or earpiece device, a device embedded in glasses or other devices worn on the user's head, or other wearable or miniature devices), a television, a computer display that does not include an embedded computer, a gaming device, a navigation device, an embedded system (such as a system in which an electronic device with a display is installed in a kiosk or a car), a device that implements the functionality of two or more of these devices, or other electronic devices. Figure 1 , Figure 2a , Figure 2b In the exemplary configuration of FIG. 1 , the electronic device 10 is a portable device such as a cellular phone, a media player, a tablet computer, or other portable computing device. Other configurations may be used for the electronic device if desired. Figure 1 , Figure 2a , Figure 2b The examples are exemplary only.
[0039] like Figure 1 and Figure 2a , Figure 2b As shown, the electronic device 10 may include a foldable body 100 and a flexible screen assembly 200 . The flexible screen assembly 200 may be connected to the foldable body 100 and may bend as the foldable body 100 is folded.
[0040] The flexible screen assembly 200 can form a display surface of the electronic device 10 for displaying information such as images and texts. The flexible screen assembly 200 can include a display screen such as a liquid crystal display (LCD) or an organic light-emitting diode (OLED) display screen.
[0041] The foldable body 100 may be a thin plate or sheet structure, or a hollow frame structure. The foldable body 100 is used to provide support for the electronic components in the electronic device 10 so as to install the electronic components in the electronic device 10 together. For example, the electronic components such as the camera, receiver, circuit board, battery, etc. in the electronic device 10 can be installed on the foldable body 100 for fixing.
[0042] like Figure 1As shown, the foldable body 100 may include a first body portion 110 and a second body portion 120, and the second body portion 120 and the first body portion 110 may be arranged opposite to each other along the axis S1. The foldable body 100 may include a first side 111, a second side 112, a third side 113 and a fourth side 114 connected in sequence, wherein the first side 111 is arranged opposite to the third side 113, and the second side 112 is arranged opposite to the fourth side 114.
[0043] It can be understood that the first side 111, the second side 112, the third side 113 and the fourth side 114 of the foldable body 100 are described from the overall appearance of the foldable body 100. The first side 111, a part of the second side 112 and a part of the fourth side 114 may be the outer contour of the first body portion 110 of the foldable body 100; the third side 113, another part of the second side 112 and another part of the fourth side 114 may be the outer contour of the second body portion 120 of the foldable body 100.
[0044] The second side 112 may form an angle θ during the folding process of the foldable body 100, such as Figure 1 As shown, when the angle θ is 180 degrees, the first body portion 110 and the second body portion 120 can be in the same plane, so that the foldable body 100 can be unfolded. Figure 2b As shown, the first body portion 110 and the second body portion 120 can be folded together along the axis S1. When the angle θ is 0 degrees or 360 degrees, the foldable body 100 is in a fully folded state. The first body portion 110 and the second body portion 120 can be completely folded together to make the foldable body 100 in a fully folded state. Figure 2a As shown, when the angle θ is between 0 degrees and 180 degrees, or between 180 degrees and 360 degrees, the first main body portion 110 and the second main body portion 120 are in a middle folded state, and the first main body portion 110 and the second main body portion 120 are close to each other. At this time, the first distance between the first main body portion 110 and the second main body portion 120 is smaller than the second distance between the first main body portion 110 and the second main body portion 120 in the unfolded state.
[0045] Wherein, the flexible screen assembly 200 is connected to the foldable body 100, illustratively, the first end 210 of the flexible screen assembly 200 is connected to the first body part 110, and the second end 220 of the flexible screen assembly 200 is connected to the second body part 120. When the foldable body 100 is in the unfolded state, the flexible screen assembly 200 can make the first end 210 and the second end 220 of the flexible screen assembly 200 be in the same plane as the foldable body 100 is unfolded, and the flexible screen assembly 200 is in the unfolded state. When the foldable body 100 is in the middle folded state or the fully folded state, the flexible screen assembly 200 can also be folded along the axis S1 as the foldable body 100 is folded, so that the first end 210 and the second end 220 of the flexible screen assembly 200 can be close to each other or completely close to each other and folded together.
[0046] It can be understood that the connection between the first main body portion 110 and the second main body portion 120 of the foldable body 100 and the connection between the first end 210 and the second end 220 of the flexible screen assembly 200 can be made of flexible material or bendable material, so that the foldable body 100 and the flexible screen assembly 200 can be in the above-mentioned folded state.
[0047] Among them, please refer to Figure 3 , Figure 4a and Figure 4b , Figure 3 A second structural diagram of an electronic device provided in an embodiment of the present application, Figure 4a and Figure 4b for Figure 3 The foldable body 100 includes not only the first body portion 110 and the second body portion 120 , but also a rotating shaft 130 .
[0048] like Figure 3 As shown, the first body portion 110 and the second body portion 120 may be connected to the rotation shaft 130 respectively, and the first body portion 110 and the second body portion 120 may be rotatably connected together around the rotation shaft 130 .
[0049] like Figure 3 As shown in FIG. 1 , when the angle θ is 180 degrees, the first body portion 110, the second body portion 120, and the rotating shaft 130 can be located in the same plane, so that the foldable body 100 can be unfolded. Figure 4b As shown, the first body part 110 and the second body part 120 of the foldable body 100 can rotate along the rotation axis 130. When the angle θ is 0 degrees or 360 degrees, the foldable body 100 is in a fully folded state. At this time, the first body part 110 and the second body part 120 can be completely folded together, so that the foldable body 100 is in a fully folded state. Figure 4aAs shown, when the angle θ is between 0 degrees and 180 degrees, or between 180 degrees and 360 degrees, the first main body portion 110 and the second main body portion 120 are in a middle folded state, and the first main body portion 110 and the second main body portion 120 are close to each other. At this time, the first distance between the first main body portion 110 and the second main body portion 120 is smaller than the second distance between the first main body portion 110 and the second main body portion 120 in the unfolded state.
[0050] The flexible screen assembly 200 may include a first display portion 230 and a second display portion 240, and the connection between the first display portion 230 and the second display portion 240 may be a flexible screen, that is, the connection between the first display portion 230 and the second display portion 240 may be bendable. When the foldable body 100 is in the unfolded state, the first display portion 230 and the second display portion 240 of the flexible screen assembly 200 may be in the same plane so that the flexible screen assembly 200 is unfolded. When the foldable body 100 is in the middle folded state or the fully folded state, the first display portion 230 and the second display portion 240 of the flexible screen assembly 200 may be bent along the connection between the first display portion 230 and the second display portion 240 as the foldable body 100 is folded, so that the first display portion 230 and the second display portion 240 of the flexible screen assembly 200 may be close to each other or completely folded together.
[0051] It is understandable that the flexible screen assembly 200 can be made of flexible materials, and the first body portion 110 and the second body portion 120 of the foldable body 100 can be made of rigid materials, so that the foldable body 100 can support the flexible screen assembly 200.
[0052] It can be understood that the unfolded state, intermediate folded state and fully folded state of the foldable body 100 are divided according to the angle θ formed by the second side 112 during the folding process. When the angle θ is 180 degrees, the foldable body 100 is considered to be in the unfolded state; when the angle θ is 0 degrees or 360 degrees, the foldable body 100 is considered to be in the fully folded state; when the angle θ is between 0 degrees and 180 degrees, or between 180 degrees and 360 degrees, the foldable body 100 is considered to be in the intermediate folded state.
[0053] It should be noted that the above are merely illustrative examples of the foldable body 100 and the flexible screen assembly 200, and the protection scope of the embodiments of the present application is not limited thereto. Other structures of the foldable body 100 having an unfolded state and a folded state, and other structures of the flexible screen assembly 200 having an unfolded state and a folded state are all within the protection scope of the embodiments of the present application.
[0054] It should be understood that, in the description of this application, terms such as "first", "second", etc. are only used to distinguish similar objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.
[0055] The electronic device 10 of the embodiment of the present application may include, in addition to the foldable body 100 and the flexible screen assembly 200, an antenna radiator. Figure 5 , Figure 5 The third structural diagram of the electronic device provided in the embodiment of the present application is as follows: The electronic device 10 may further include a first radiator 140 , a second radiator 150 , a first adjustment circuit 300 , a first feed source 400 and a third feed source 500 .
[0056] The first radiator 140 and the second radiator 150 may be arranged on the outer edge of the foldable body 100, or the first radiator 140 and the second radiator 150 may be arranged inside the foldable body 100. At least a portion of the first radiator 140 may be arranged on the first side 111 of the foldable body 100, and the first radiator 140 is grounded. The so-called being arranged on the first side 111 of the foldable body 100 may mean that the first radiator 140 is arranged on the outer edge of the first side 111, and the first radiator 140 is a metal branch on the outer edge of the first side 111 of the foldable body 100. The electronic device 10 may use the metal branch as the first radiator 140 and use it to transmit wireless signals. The so-called first edge 111 arranged on the foldable body 100 may also mean that the first radiator 140 is arranged inside the foldable body 100 corresponding to the first edge 111. The first radiator 140 may be a conductor arranged inside the foldable body 100 corresponding to the first edge 111. The electronic device 10 may use the conductor as the first radiator 140 and use it to transmit wireless signals.
[0057] Among them, the first feed source 400 can be electrically connected to the second radiator 150, and a first feeding point 151 can be provided on the second radiator 150. The first feed source 400 can be electrically connected to the second radiator 150 through the first feeding point 151. The first feed source 400 can provide a first excitation signal to the second radiator 150 through the first feeding point 151 so that the second radiator 150 can transmit wireless signals to the outside.
[0058] It is understandable that a first grounding point 152 may be further provided on the second radiator 150 , and the first grounding point 152 may be electrically connected to a ground plane (not shown) of the electronic device 10 to achieve grounding of the second radiator 150 .
[0059] The third feed source 500 may be electrically connected to the first radiator 140, and a feeding point (eg Fig.17 The third feed source 500 can be electrically connected to the first radiator 140 through the third feeding point 148 in the figure, and the third feed source 500 can feed a signal into the first radiator 140 so that the first radiator 140 can transmit a wireless signal outward.
[0060] It is understandable that a grounding point (eg Fig.17 The third grounding point 146 and the fourth grounding point 147 can be electrically connected to the ground plane of the electronic device 10 to achieve grounding of the first radiator 140.
[0061] like Figure 5 As shown, when the third feed source 500 feeds a wireless signal to the first radiator 140, the current I1 may flow on the first radiator 140, and the current I1 flowing through the first radiator 140 may form a current zero point (the current zero point is the electric field strength point) on the first radiator 140, and at least part of the current I1 may be distributed on the first side 111, for example, Figure 5 The medium current I1 may be distributed on the first side 111 and the second side 112 . The current I1 may form a changing electric field near the first side 111 where the first radiator 140 is located, so that the first radiator 140 may transmit a wireless signal.
[0062] Please continue to refer to Figure 5 The second radiator 150 may include a first portion 154 and a second portion 155 connected to each other, the first portion 154 may be disposed on the second side 112, at least a portion of the second portion 155 may be disposed on the third side 113, and the second radiator 150 may be formed in an "L" shape and disposed in a corner of the electronic device 10, such as the lower right corner. The second radiator 150 may be grounded through the first portion 154, may be grounded through the second portion 155, or both the first portion 154 and the second portion 155 may be grounded.
[0063] It can be understood that the first portion 154 is disposed on the second side 112, which may mean that the first portion 154 is disposed on the outer edge of the second side 112, or that the first portion 154 is disposed inside the foldable body 100 corresponding to the second side 112. Similarly, the second portion 155 may be disposed on at least the third side 113, which may mean that the second portion 155 is disposed on the outer edge of the third side 113, or that the second portion 155 is disposed inside the foldable body 100 corresponding to the third side 113.
[0064] like Figure 5As shown, when the first feed source 400 feeds a wireless signal into the second radiator 150, the current I2 can flow on the second radiator 150, and the current flowing through the second radiator 150 can form a current zero point on the second radiator 150, and form a changing electric field near the second side 112 and the third side 113 where the second radiator 150 is located, so that the second radiator 150 can transmit wireless signals.
[0065] The first regulating circuit 300 may be electrically connected to the first portion 154 of the second radiator 150 . A first electrical connection point 153 may be disposed on the first portion 154 of the second radiator 150 , and one end of the first regulating circuit 300 may be electrically connected to the first electrical connection point 153 .
[0066] It is understandable that the first adjustment circuit 300 may include one or more of an inductor and a capacitor. Multiple inductors and capacitors may be connected in parallel, in series, or partially in series and partially in parallel. The first adjustment circuit 300 may change the capacitance and inductance values connected to the first portion 154 of the second radiator 150 to change the electric field strength point of the current flowing through the second radiator 150.
[0067] Please refer to Figure 6 , Figure 6 for Figure 5 The first current diagram of the electronic device shown. Figure 6 Please also refer to Figure 2a , 2b , 4a and 4b. When the angle θ is within the first preset range, the foldable body 100 can be in an intermediate folding state or a fully folded state, the first radiator 140 located on the first side 111 can be close to the second radiator 150 located on the third side 113, and the current I1 flowing through the first radiator 140 is mainly distributed in the portion of the first radiator 140 located on the first side 111. At this time, the first regulating circuit 300 can form a current zero point of the second radiator 150 on the first portion 154 located on the second side 112, and the first regulating circuit 300 can make the current density of the second radiator 150 distributed in the first portion 154 greater than the current density distributed in the second portion 155. At this time, the current I2 is mainly concentrated on the first part 154 of the second radiator 150, and a small part is concentrated on the second part 155 of the second radiator 150. The electric field of the second radiator 150 is mainly formed near the second edge 112, and the electric field strength point is mainly formed near the current zero point. The second radiator 150 mainly transmits wireless signals through the first part 154 located on the second edge 112.
[0068] It can be understood that the first preset range can be that the angle θ is 0 degrees or 360 degrees, or the angle θ is between 0 degrees and 180 degrees, or between 180 degrees and 360 degrees. At this time, the foldable body 100 can be in an intermediate folding state or a fully folded state, and the first edge 111 and the third edge 113 are close to each other.
[0069] It can be understood that the first preset range can be the angle θ or can be between 0 degrees and 150 degrees, or between 210 degrees and 360 degrees. At this time, the distance between the first side 111 and the third side 113 is closer, and the interference between the first radiator 140 located on the first side 111 and the second radiator 150 located on the third side 113 is greater.
[0070] In the electronic device 10 of the embodiment of the present application, when the angle θ is within the first preset range, the electric field of the first radiator 140 can be formed near the first side 111, and the electric field of the second radiator 150 can be formed near the second side 112. Since the angle θ is within the first preset range, the first side 111 and the third side 113 are close to each other, the second side 112 and the fourth side 114 are close to each other, and the second side 112 intersects with the first side 111 and the third side 113, so that the second side 112 is far away from the first side 111 and the third side 113, so that the electric field radiation area of the second radiator 150 is not in the same area as the electric field radiation area of the first radiator 140, the isolation between the first radiator 140 and the second radiator 150 is improved, and the interference between the second radiator 150 and the first radiator 140 is small.
[0071] Among them, please refer to Figure 7 , Figure 7 A fourth structural diagram of an electronic device provided in an embodiment of the present application. The electronic device 10 in the embodiment of the present application may further include a second regulating circuit 600, and the second regulating circuit 600 may be electrically connected to the second radiator 150. For example, the second regulating circuit 600 may be electrically connected to the second portion 155 of the second radiator 150. A second electrical connection point 157 may be provided on the second portion 155 of the second radiator 150, and the second regulating circuit 600 may be electrically connected to the second electrical connection point 157.
[0072] It is understandable that the second adjustment circuit 600 may include one or more of an inductor and a capacitor. Multiple inductors and capacitors may be connected in parallel, in series, or partially in series and partially in parallel. The second adjustment circuit 600 may change the capacitance and inductance values connected to the second portion 155 of the second radiator 150 to change the electric field strength point of the current flowing through the second radiator 150.
[0073] Please continue to refer to Figure 7, when the angle θ is within the second preset range, the foldable body 100 can be in an unfolded state, the portion of the first radiator 140 located on the first side 111 can be away from the second portion 155 of the second radiator 150 located on the third side 113, and the second regulating circuit 600 can form the current zero point of the second radiator 150 on the second portion 155 located on the third side 113, and the second regulating circuit 600 can make the current density distributed in the second portion 155 greater than the current density distributed in the first portion 154. At this time, the current is mainly concentrated on the second portion 155 of the second radiator 150, and a small portion is concentrated on the first portion 154 of the second radiator 150. The electric field of the second radiator 150 is mainly formed near the third side 113, and the electric field strength point of the second radiator 150 is mainly formed near the current zero point. The second radiator 150 mainly transmits wireless signals through the second portion 155 located on the third side 113.
[0074] It can be understood that the second preset range can be an angle θ of 180 degrees. At this time, the foldable body 100 can be in an unfolded state, the first side 111 and the third side 113 are far away from each other and the distance is the farthest, and the interference between the first radiator 140 located on the first side 111 and the second radiator 150 located on the third side 113 is minimal.
[0075] It can be understood that the second preset range can be that the angle θ can also be 150 degrees to 180 degrees, 180 degrees to 210 degrees. At this time, the distance between the first side 111 and the third side 113 is also closer, and the interference between the first radiator 140 located on the first side 111 and the second radiator 150 located on the third side 113 is relatively small.
[0076] In the electronic device 10 of the embodiment of the present application, when the angle θ is within the second preset range, the electric field of the first radiator 140 can be formed near the first side 111, and the electric field of the second radiator 150 can be formed near the third side 113. Since the first side 111 and the third side 113 are far away from each other when the angle θ is within the second preset range, the electric field radiation area of the second radiator 150 and the electric field radiation area of the first radiator 140 are also far away from each other, the isolation between the first radiator 140 and the second radiator 150 is relatively large, and the interference between the second radiator 150 and the first radiator 140 is relatively small.
[0077] In the electronic device 10 of the embodiment of the present application, the second adjustment circuit 600 is electrically connected to the second part 155. Since the second part 155 is not easily held by the user's hand, the second part 155 is less disturbed after being electrically connected to the second adjustment circuit 600. At the same time, the second adjustment circuit 600 is electrically connected to the second part 155, and the second adjustment circuit 600 can more easily change the capacitance and inductance values connected to the second part 155, so that the second adjustment circuit 600 can more easily form the electric field strength point of the second radiator 150 in the second part 155.
[0078] It should be noted that the electronic device 10 of the embodiment of the present application can also form the current zero point of the second radiator 150 in the second part 155 by adjusting the capacitance and inductance values of the first adjustment circuit 300; the electronic device 10 can also form the current zero point of the second radiator 150 in the second part 155 by disconnecting the first adjustment circuit 300.
[0079] It should be noted that, in the electronic device 10 of the embodiment of the present application, the first regulating circuit 300 and the second regulating circuit 600 can work together. That is, when the angle θ is within the second preset range, the first regulating circuit 300 and the second regulating circuit 600 can jointly make the current flowing through the second radiator 150 concentrated on the second part 155. In this process, the regulation of the first regulating circuit 300 is the main one, and the regulation of the second regulating circuit 600 is the auxiliary one. When the angle θ is within the first preset range, the first regulating circuit 300 and the second regulating circuit 600 can make the current flowing through the second radiator 150 concentrated on the first part 154. In this process, the regulation of the second regulating circuit 600 is the main one, and the regulation of the first regulating circuit 300 is the auxiliary one.
[0080] Please refer again to Figure 7 The second part 155 of the second radiator 150 of the embodiment of the present application may include a first sub-part 1551 and a second sub-part 1552 that are spaced apart. The first sub-part 1551 may be connected to the first part 154 of the second radiator 150 as a whole. A first gap 1553 may be provided between the second sub-part 1552 and the first sub-part 1551. A first grounding point 152 may be provided at one end of the first sub-part 1551 away from the first gap 1553, and the first sub-part 1551 may be grounded through the first grounding point 152. A second grounding point 156 may be provided at one end of the second sub-part 1552 away from the first gap 1553, and the second sub-part 1552 may be grounded through the second grounding point 156. Thus, the two free ends of the first sub-part 1551 and the second sub-part 1552 are arranged relative to each other.
[0081] It can be understood that the first feeding point 151 can be set at the first part 154, the first sub-part 1551 or the connection between the first part 154 and the first sub-part 1551 of the second radiator 150, so that the first feed source 400 can be electrically connected to the first part 154, the first sub-part 1551 or the connection between the first part 154 and the first sub-part 1551 of the second radiator 150.
[0082] In the electronic device 10 of the embodiment of the present application, the first feed source 400 is connected to the first part 154 or the first sub-part 1551. When the foldable body is in a folded state, the first feed source 400 can feed a first excitation signal to the first part 154 or the first sub-part 1551, so that the first adjustment circuit 300 can concentrate the current flowing through the second radiator 150 on the first part 154.
[0083] In the electronic device 10 of the embodiment of the present application, when the angle θ is within the second preset range, the radiation branch between the first feeding point 151 and the end of the first sub-portion 1551 close to the first slot 1553 can generate a first working mode; the radiation branch between the first feeding point 151 and the second electrical connection point 157 can generate a second working mode through electromagnetic coupling; the radiation branch between the first feeding point 151 and the second grounding point 156 can generate a third working mode through electromagnetic coupling. Thus, when the angle θ is within the second preset range, the second radiator 150 of the present application can radiate wireless signals of a wider frequency band, and the frequency band range of the wireless signals transmitted by the second radiator 150 can be expanded.
[0084] For example, please combine Figure 7 Please also refer to Figures 8 to 10 , Figure 8 for Figure 7 The schematic diagram of the current of the first mode generated by the second radiator is shown in FIG. Fig. 9 for Figure 7 The schematic diagram of the second mode current generated by the second radiator is shown in FIG. Fig.10 for Figure 7 When the first feed source 400 feeds the first excitation signal to the second radiator 150, the second adjustment circuit 600 or the second adjustment circuit 600 and the first adjustment circuit 300 jointly change the capacitance and inductance values electrically connected to the second radiator 150 so that the second radiator 150 can transmit wireless signals of different frequencies.
[0085] like Figure 7 and Figure 8As shown, when the first feed source 400 feeds the first excitation signal to the second radiator 150, the radiation branch between the first feeding point 151 of the second radiator 150 and the end of the first sub-section 1551 close to the first slot 1553 can generate a first working mode and can resonate in the working frequency band of the antenna mode of a quarter wavelength. The current I21 flows in the second radiator 150 and is mainly concentrated in the area from the first feeding point 151 to the first sub-section 1551. The end of the first sub-section 1551 close to the first slot 1553 (such as Figure 8 Point A shown in the figure can be the current zero point of the current I21. The current I21 can flow from the first feeding point 151 connected to the first feed source 400 to the direction where the first gap 1553 is located. Thus, the first electric field formed by the current I21 is formed in the area where the first part 154 to the first sub-part 1551 is located. The electric field strength point of the first electric field is formed at the current zero point of the current I21, that is, in the area near the first gap 1553. The first electric field is concentrated near the third side 113 at the bottom of the electronic device 10.
[0086] like Fig. 9 As shown, when the first feed source 400 feeds the first excitation signal to the second radiator 150, the radiation branch between the first feed point 151 and the second electrical connection point 157 of the second radiator 150 can generate a second working mode through electromagnetic coupling and can resonate to work in the working frequency band of the antenna mode of half the wavelength. The current I22 flows in the second radiator 150 and is mainly concentrated in the area where the first feed point 151 to the second electrical connection point 157 of the second sub-section 1552 is located. There is a current zero point (such as Fig. 9 The current I22 may flow from the first feed point 151 connected to the first feed source 400 and the second electrical connection point 157 connected to the second regulating circuit 600 to the current zero point B. Thus, the second electric field formed by the current I22 is formed in the area from the first feed point 151 to the second electrical connection point 157 of the second sub-part 1552, and the electric field strength point of the second electric field is formed at the current zero point B of the current I22, that is, in the area near the first slit 1553 to the second electrical connection point 157, and the second electric field is concentrated near the third side 113 of the bottom of the electronic device 10.
[0087] like Fig.10As shown, when the first feed source 400 feeds the first excitation signal to the second radiator 150, the radiation branch between the first feed point 151 and the second grounding point 156 of the second radiator 150 can generate a third working mode through electromagnetic coupling and can resonate in the working frequency band of the antenna mode of a wavelength. The current I23 flows in the second radiator 150 and is mainly concentrated in the area where the first feed point 151 to the second grounding point 156 of the second sub-section 1552 is located. There are two current zero points (such as Fig.10 As shown in points C and D, point C is formed at the end of the second sub-part 1552 and close to the first gap 1553, and point D is formed in the area of the second electrical connection point 157 electrically connected to the second regulation circuit 600), the flow direction of the current I23 can be from the first feeding point 151 to the current zero point C, the current zero point C flows to the current zero point D, and the second grounding point 156 flows to the current zero point D, so that the third electric field formed by the current I23 is formed in the area from the first feeding point 151 to the second grounding point 156 of the second sub-part 1552, and the electric field strength point of the second electric field is formed at the current zero points C and D of the current I23, that is, it is formed near the first gap 1553 and the second electrical connection point 157, and the third electric field is concentrated near the third side 113 at the bottom of the electronic device 10.
[0088] In the electronic device 10 of the embodiment of the present application, under the action of the second adjustment circuit 600 or the first adjustment circuit 300 and the second adjustment circuit 600, when the angle θ is within the second preset range, the second radiator 150 can radiate the above three working modes, so that the second radiator 150 can transmit wireless signals with a wider frequency band.
[0089] For example, please refer to Fig.11 , Fig.11 for Figure 7 The isolation curve diagram of the second radiator when transmitting the first excitation signal is shown. Among them, curve S1 is the isolation curve diagram of the second radiator 150 transmitting the first excitation signal when the inductance value of the first adjustment circuit 300 is 3 nanohenry (nH) and the second adjustment circuit 600 is disconnected. Curve S2 is the isolation curve diagram of the second radiator 150 transmitting the first excitation signal when the inductance value of the first adjustment circuit 300 is 5 nanohenry (nH) and the inductance value of the second adjustment circuit 600 is 3 nanohenry (nH). Curve S3 is the isolation curve diagram of the second radiator 150 transmitting the first excitation signal when both the first adjustment circuit 300 and the second adjustment circuit 600 are disconnected.
[0090] It can be seen from curve S1 that the isolation of the second radiator 150 at a frequency of 1.9 GHz (1900 MHz) is -17, which is relatively good, and the second radiator 150 can transmit a 1.9 GHz wireless signal. It can be seen from curve S2 that the isolation of the second radiator 150 at a frequency of 2.3 GHz (2300 MHz) is -19, which is relatively good, and the second radiator 150 can transmit a 2.3 GHz wireless signal. It can be seen from curve S3 that the isolation of the second radiator 150 at a frequency of 2.6 GHz (27000 MHz) is -31, which is relatively good, and the second radiator 150 can transmit a 2.6 GHz wireless signal.
[0091] It can be seen from the curves S1 to S3 that the second radiator 150 can cover the wireless signal of 1900MHz to 2700MHZ under the action of the first adjustment circuit 300 and the second adjustment circuit 600. Therefore, the second radiator 150 of the embodiment of the present application can transmit medium and high frequency radio frequency signals of 1710MHz to 2690MHz, and the second radiator 150 also has better isolation when transmitting medium and high frequency radio frequency signals.
[0092] It should be noted that the above are only several exemplary working modes of the second radiator 150. When the angle θ is within the second preset range, the second radiator 150 can also radiate other working modes by adjusting the inductance and capacitance values of the first adjustment circuit 300 and the second adjustment circuit 600. The embodiment of the present application does not limit the working mode of the second radiator 150 when it is in the unfolded state.
[0093] In the electronic device 10 of the embodiment of the present application, the second part 155 of the second radiator 150 includes the first sub-part 1551 and the second sub-part 1552, and when the angle θ is within the first preset range, the first part 154 can generate the fourth working mode; the radiation branch from the first part 154 to the first part 154 can generate the fifth working mode. Therefore, when the angle θ is within the first preset range, the second radiator 150 of the embodiment of the present application can radiate wireless signals of a wider frequency band, and the frequency band range of the wireless signals transmitted by the second radiator 150 can be expanded.
[0094] For example, please combine Figure 7 Please also refer to Figure 12 to Figure 13 , Fig.12 for Figure 7 The schematic diagram of the fourth mode current generated by the second radiator is shown in FIG. Fig.13 for Figure 7When the first feed source 400 feeds the first excitation signal to the second radiator 150, the first adjustment circuit 300 or the first adjustment circuit 300 and the second adjustment circuit 600 jointly change the capacitance and inductance values electrically connected to the second radiator 150 so that the second radiator 150 can transmit wireless signals of different frequencies.
[0095] like Fig.12 As shown, when the first feed source 400 feeds the first excitation signal to the second radiator 150, the radiation branch between the end of the first portion 154 of the second radiator 150 away from the first sub-portion 1551 and the first feeding point 151 can generate a fourth working mode and can resonate in the working frequency band of the lateral quarter-wavelength antenna mode. The current I24 flows in the second radiator 150 and is mainly concentrated in the area from the end of the first portion 154 away from the first sub-portion 1551 to the first feeding point 151. The end of the first portion 154 away from the first feeding point 151 (such as Fig.12 The point E shown in the figure may be the current zero point of the current I24, and the current I24 may flow from the first feeding point 151 to the direction where the end of the first part 154 of the second radiator 150 away from the first sub-part 1551 is located, so that the fourth electric field formed by the current I24 is formed in the area from the first part 154 to the first feeding point 151, and the electric field strength point of the fourth electric field is formed at the current zero point of the current I24, that is, formed in the area where the first part 154 is away from the first feeding point 151, and the fourth electric field is concentrated near the second lateral side 112 of the electronic device 10.
[0096] like Fig.13 As shown, when the first feed source 400 feeds the first excitation signal to the second radiator 150, the radiation branch between the first part 154 and the end of the first sub-part 1551 of the second radiator 150 near the first slot 1553 can generate the fifth working mode and can resonate in the working frequency band of the antenna mode of half wavelength in the lateral direction. The current I25 flows in the second radiator 150 and is mainly concentrated in the area where the first part 154 to the first sub-part 1551 are located. There is a current zero point (such as Fig.13Point F is shown in the figure, and point F is formed in the area where the first part 154 is connected to the first sub-part 1551), and the flow direction of the current I25 can be from the end of the first part 154 far away from the current zero point, and the end of the first sub-part 1551 far away from the current zero point to the current zero point. Thus, the fifth electric field formed by the current I25 is formed in the area where the first part 154 to the first sub-part 1551 is located, and the electric field strength point of the fifth electric field is formed at the current zero point F of the current I25, that is, it is formed in the area where the first part 154 is connected to the first sub-part 1551, and the fifth electric field is concentrated near the second side 112 of the side of the electronic device 10 and near the third side 113 of the bottom.
[0097] In the electronic device 10 of the embodiment of the present application, under the action of the first adjustment circuit 300 and / or the second adjustment circuit 600, when the angle θ is within the first preset range, the second radiator 150 can radiate the above two working modes, so that the second radiator 150 can transmit wireless signals with a wider frequency band.
[0098] Furthermore, when the angle θ is within the first preset range, the second radiator 150 of the embodiment of the present application can also transmit medium and high frequency radio frequency signals of 1710 MHz to 2690 MHz, and the second radiator 150 also has better isolation when transmitting medium and high frequency radio frequency signals. Thus, the second radiator 150 can transmit wireless signals of the same frequency band when the foldable body 100 is in the unfolded state and the folded state.
[0099] It is understandable that the above are only several exemplary working modes of the second radiator 150. When the angle θ is within the first preset range, the second radiator 150 can also radiate other working modes by adjusting the inductance and capacitance values of the first adjustment circuit 300 and the second adjustment circuit 600. The embodiment of the present application does not limit the working mode of the second radiator 150 when it is in the folded state.
[0100] In the electronic device 10 of the embodiment of the present application, when the first radiator 140 transmits the first excitation signal, each frequency band has two working modes, namely, bottom and side. Figure 8 and Fig.12 It can be seen that the first radiator 140 has two quarter-wavelength working modes, the bottom and the side. Fig. 9 and Fig.13It can be seen that the first radiator 140 has two half-wavelength working modes, the bottom and the side. Therefore, the electronic device 10 can control the first adjustment circuit 300 and the second adjustment circuit 600 according to the folded state or unfolded state of the foldable body 100, so that when the foldable body 100 is in the folded state, the second radiator 150 can excite the side working mode, and when the foldable body 100 is folded and unfolded, the second radiator 150 can excite the bottom working mode, thereby ensuring that the second radiator 150 has good radiation performance when the electronic device 10 is in different forms.
[0101] When the angle θ is within the first preset range, the second radiator 150 of the embodiment of the present application can radiate a side working mode, which can reduce the interference between the second radiator 150 and the first radiator 140 in the folded state. Fig.14 and Fig.15 , Fig.14 is a schematic diagram of the isolation curve between the second radiator and the first radiator when the second radiator is in the bottom radiation working mode, Fig.15 This is a schematic diagram of an isolation curve between the second radiator and the first radiator when the second radiator is in a side radiation working mode.
[0102] like Fig.14 As shown, curve S4 is a reflection coefficient curve of the second radiator 150 when the second radiator 150 radiates the bottom working mode; curve S5 is a reflection coefficient curve of the first radiator 140 when it is working. Curve S6 is an isolation curve of the first radiator 140 and the second radiator 150. It can be seen from curves S4 and S6 that when the first radiator 140 is in the frequency band of 1.575GHz, the isolation between it and the second radiator 150 is -10dB; when the first radiator 140 is in the frequency band of 2.4GHz, the isolation between it and the second radiator 150 is -7dB. It can be seen from curves S5 and S6 that when the second radiator 150 is in the frequency band of 2.1GHz, the isolation between it and the second radiator 150 is -11dB; when the first radiator 140 is in the frequency band of about 2.6GHz, the isolation between it and the second radiator 150 is -10dB.
[0103] like Fig.15As shown, curve S7 is a reflection coefficient curve of the second radiator 150 when the second radiator 150 is in the radiation side working mode; curve S8 is a reflection coefficient curve of the first radiator 140 when it is working. Curve S9 is an isolation curve of the first radiator 140 and the second radiator 150. It can be seen from curves S7 and S9 that when the first radiator 140 is in the frequency band of 1.575GHz, the isolation between it and the second radiator 150 is -12dB; when the first radiator 140 is in the frequency band of 2.4GHz, the isolation between it and the second radiator 150 is -11dB. It can be seen from curves S8 and S6 that when the second radiator 150 is in the frequency band of 2.1GHz, the isolation between it and the second radiator 150 is -13dB; when the first radiator 140 is in the frequency band of about 2.6GHz, the isolation between it and the second radiator 150 is -17dB.
[0104] By comparing curves S6 and S9, it can be seen that when the second radiator 150 is in the side working mode in the same frequency band, the isolation between it and the first radiator 140 is relatively large. For example, in the frequency band of 1.575 GHz, the isolation between the first radiator 140 and the second radiator 150 in curve S6 is only -10 dB, while in curve S7, the isolation between the first radiator 140 and the second radiator 150 can be -12 dB. Obviously, when the second radiator 150 is in the side working mode, the isolation between it and the first radiator 140 is relatively large.
[0105] In the electronic device 10 of the embodiment of the present application, when the angle θ is within the first preset range, the second radiator 150 can radiate the side working mode, and the electric field radiation area of the second radiator 150 is not in the same area as the electric field radiation area of the first radiator 140, thereby improving the isolation between the first radiator 140 and the second radiator 150, and the interference between the second radiator 150 and the first radiator 140 is small.
[0106] In addition to controlling the working mode of the second radiator 150 through the first regulating circuit 300 and the second regulating circuit 600, the electronic device 10 can also achieve the above control through other methods. For example, please refer to Fig.16 , Fig.16 The fifth structural diagram of the electronic device provided in the embodiment of the present application. The electronic device 10 may further include a third regulating circuit 700, which may be electrically connected to the second sub-portion 1552, and a third electrical connection point 159 may be provided on the second sub-portion 1552, and the third electrical connection point 159 may be provided between the first grounding point 152 and the second electrical connection point 157, so that the third regulating circuit 700 is closer to the first gap 1553 than the second regulating circuit 600.
[0107] It is understandable that the third adjustment circuit 700 may include one or more of an inductor and a capacitor. Multiple inductors and capacitors may be connected in parallel, in series, or partially in series and partially in parallel. The third adjustment circuit 700 may change the capacitance and inductance values connected to the second subsection 1552 of the second radiator 150 to change the current zero point of the current flowing through the second radiator 150.
[0108] It can be understood that the third adjustment circuit 700 and the second adjustment circuit 600 are both electrically connected to the second sub-part 1552, and the third adjustment circuit 700 can jointly adjust the bottom working mode of the second radiator 150 with the second adjustment circuit 600, so that the second radiator 150 can adjust more bottom working modes, thereby covering more working frequency bands.
[0109] Please continue to refer to Figure 7 The electronic device 10 may further include a second feed source 800 , which may be electrically connected to the second sub-portion 1552 . The second feed source 800 may provide a second excitation signal and may feed the second excitation signal into the second sub-portion 1552 .
[0110] It can be understood that a second feeding point 158 can be provided on the second sub-portion 1552, and the second feed source 800 can be electrically connected to the second feeding point 158 of the second sub-portion 1552. The second feeding point 158 can be provided between the second electrical connection point 157 and the second grounding point 156. Thus, when the second feed source 800 feeds the second excitation signal to the second sub-portion 1552, the current can return to the ground from the second grounding point 156, and the second sub-portion 1552 can radiate the second excitation signal.
[0111] It is understandable that the second excitation signal may be a low-frequency signal. That is, the second sub-section 1552 may also transmit a low-frequency signal, and the frequency range of the low-frequency signal may be between 703 MHz and 960 MHz.
[0112] In the electronic device 10 of the embodiment of the present application, the first feed source 400 is arranged between the first portion 154 and the first sub-portion 1551 of the second radiator 150, and the second feed source 800 is arranged on the second sub-portion 1552. The first portion 154, the first sub-portion 1551 and the second sub-portion 1552 of the second radiator 150 can transmit medium- and high-frequency radio frequency signals; the second sub-portion 1552 of the second radiator 150 can transmit low-frequency radio frequency signals. Thus, the second radiator 150 can transmit medium- and high-frequency radio frequency signals and low-frequency radio frequency signals, and the second radiator 150 can achieve multiplexing, which can save the space occupied by the radiator in the electronic device 10.
[0113] Among them, please refer to Fig.17 , Fig.17The sixth structural diagram of the electronic device provided in the embodiment of the present application. The first radiator 140 may include a third portion 141, a fourth portion 142 and a fifth portion 143. The third portion 141 is disposed on the second side 112, the fourth portion 142 may be disposed on the first side 111, and the fourth portion 142 and the third portion 141 are connected as a whole to form an "L"-shaped structure; the fifth portion 143 is disposed on the first side 111, and a second gap 144 is provided between the fifth portion 143 and the fourth portion 142, and the free end of the fifth portion 143 and the free end of the fourth portion 142 may be disposed relative to each other.
[0114] It can be understood that the third portion 141 being disposed on the second side 112 may refer to the third portion 141 being disposed on the outer edge of the second side 112, or may refer to the third portion 141 being disposed inside the foldable body 100 corresponding to the second side 112. Similarly, the fourth portion 142 and the fifth portion 143 being disposed on the first side 111 may refer to the fourth portion 142 and the fifth portion 143 being disposed on the outer edge of the first side 111, or may refer to the fourth portion 142 and the fifth portion 143 being disposed inside the foldable body 100 corresponding to the first side 111.
[0115] It can be understood that the third part 141 of the first radiator 140 and the first part 154 of the second radiator 150 can be arranged relatively on the second edge 112, that is, a third gap 145 can be set on the second edge 112, and the third gap 145 enables the second edge 112 to form two free ends, and the two free ends can respectively form the third part 141 and the first part 154.
[0116] It can be understood that a third grounding point 146 and a fourth grounding point 147 can be set on the first radiator 140, wherein the third grounding point 146 can be set on an end of the third portion 141 away from the fourth portion 142, and the third portion 141 is grounded through the third grounding point 146. The fourth grounding point 147 can be set on an end of the fifth portion 143 away from the second slit 144, and the fifth portion 143 is grounded through the fourth grounding point 147. The above-mentioned setting positions of the third grounding point 146 and the fourth grounding point 147 in this embodiment can make the radiable branches of the first radiator 140 longer, which is more conducive to the first radiator 140 adjusting the frequency band of the transmitted wireless signal.
[0117] It can be understood that the third feeding point 148 can be set on the third part 141, the fourth part 142 or the fifth part 143 of the first radiator 140, and the third feed source 500 can be electrically connected to the third feeding point 148 to feed a signal to the first radiator 140. Preferably, the third feeding point 148 can be set in the area of the fourth part 142 close to the second slot 144, so that the fifth part 143 can be easily electromagnetically coupled with the fourth part 142 through the second slot 144.
[0118] It is understandable that the third feed source 500 may feed a third excitation signal to the first radiator 140 , and the third excitation signal may be a Global Positioning System (GPS) wireless signal and a Wireless Fidelity (Wi-Fi) wireless signal.
[0119] In the electronic device 10 of the embodiment of the present application, the first radiator 140 includes a third part 141 arranged on the second side 112 and a fourth part 142 and a fifth part 143 arranged on the first side 111. The first radiator 140 can be arranged in the upper left corner of the electronic device 10. The first radiator 140 has a higher upper hemisphere efficiency, which is convenient for communicating with satellites and is more conducive to the first radiator 140 transmitting GPS signals and Wi-Fi signals.
[0120] Among them, please refer to Fig.18 , Fig.18 The seventh structural diagram of the electronic device provided in the embodiment of the present application. The electronic device 10 may further include a third radiator 160. The third radiator 160 may be arranged at the first side 111 and the fourth side 114. The third radiator 160 may be arranged at the upper right corner of the electronic device 10 to form an "L"-shaped structure.
[0121] Exemplarily, the third radiator 160 may include a sixth portion 161, a seventh portion 162, and an eighth portion 163, wherein the sixth portion 161 is disposed on the fourth side 114 and is grounded; the seventh portion 162 is disposed on the first side 111 and is connected to the sixth portion 161 to form a whole; a fourth gap 164 is disposed between the eighth portion 163 and the seventh portion 162, and one end of the eighth portion 163 away from the fourth gap 164 is grounded. Thus, the third radiator 160 may form a radiator structure similar to that of the second radiator 150.
[0122] It can be understood that the third radiator 160 can also transmit medium and high frequency radio frequency signals. The third radiator 160 and the second radiator 150 can realize multiple-input multiple-output (Multiple-Input Multiple-Output MIMO) transmission of wireless signals such as medium and high frequency radio frequency signals to improve the signal strength and transmission speed of medium and high frequency radio frequency signals in electronic transmission.
[0123] In the electronic device 10 of the embodiment of the present application, the third radiator 160 is arranged at the first side 111 and the fourth side 114, so that the third radiator 160 is formed at the upper right corner of the electronic device 10; the second radiator 150 is arranged at the second side 112 and the third side 113, so that the second radiator 150 is formed at the lower left corner of the electronic device 10, so that the second radiator 150 and the third radiator 160 are arranged diagonally. Regardless of which hand holding posture the user is in, it is difficult to block the second radiator 150 and the third radiator 160 at the same time, so that the radiation performance of the electronic device 10 can be improved.
[0124] Based on the structure of the electronic device 10, the embodiment of the present application can also protect an electronic device control method, which is applied to the electronic device 10 of any of the above embodiments. For example, the electronic device 10 includes a foldable body 100, a first radiator 140, a second radiator 150 and a first adjustment circuit 300, the foldable body 100 includes a first side 111, a second side 112, a third side 113 and a fourth side 114 connected in sequence, the second side 112 forms an angle θ during the folding process of the foldable body 100; at least part of the first radiator 140 is arranged on the first side 111, and the current of the first radiator 140 is distributed on the first side 111; the second radiator 150 includes a first part 154 and a second part 155, the first part 154 is arranged on the second side 112, at least part of the second part 155 is arranged on the third side 113, and the first adjustment circuit 300 is electrically connected to the first part 154.
[0125] Please refer to Fig.19 , Fig.19 A first flow chart of the electronic device control method provided in the embodiment of the present application. The electronic device control method in the embodiment of the present application includes:
[0126] 101. Get the angle θ.
[0127] 102. When the angle θ is within a first preset range, control the first regulating circuit to operate so that the current density of the second radiator distributed in the first part is greater than the current density distributed in the second part.
[0128] The electronic device 10 may be provided with a sensor on the foldable body 100 to detect the angle of the angle θ. For example, sensors may be provided on the first side 111 and the third side 113, for example, a probe may be provided on the third side 113. The sensor may detect the distance between the sensor and the probe to determine whether the angle θ is within the first preset range.
[0129] Exemplarily, an angle sensor may be provided on the second side 112 and the fourth side 114. For example, an angle sensor may be provided on the shaft 130 of the foldable body 100. The angle sensor may detect the rotation angle of the shaft 130, thereby obtaining the angle θ according to the rotation angle.
[0130] It can be understood that the above are only a few exemplary examples of obtaining the angle θ, and the protection scope of the embodiments of the present application is not limited to this. Other methods for obtaining the unfolded state or folded state of the foldable body 100 are within the protection scope of the present application.
[0131] When the angle θ is within the first preset range, the foldable body 100 may be in an intermediate folded state or a fully folded state, the first side 111 and the third side 113 are close to each other, and the second side 112 and the fourth side 114 are close to each other.
[0132] It can be understood that the first preset range can be that the angle θ is 0 degrees or 360 degrees, or the angle θ is between 0 degrees and 180 degrees, or between 180 degrees and 360 degrees. At this time, the foldable body 100 can be in an intermediate folding state or a fully folded state, and the first edge 111 and the third edge 113 are close to each other.
[0133] It can be understood that the first preset range can be the angle θ or can be between 0 degrees and 150 degrees, or between 210 degrees and 360 degrees. At this time, the distance between the first side 111 and the third side 113 is closer, and the interference between the first radiator 140 located on the first side 111 and the second radiator 150 located on the third side 113 is greater.
[0134] When the angle θ is within the first preset range, the first radiator 140 located on the first side 111 can be close to the second radiator 150 located on the third side 113, and the first adjustment circuit 300 can form the current zero point of the second radiator 150 on the first part 154 located on the second side 112, and the current density distributed in the first part 154 is greater than the current density distributed in the second part 155. At this time, the current is mainly concentrated on the first part 154 of the second radiator 150, and a small part is concentrated on the second part 155 of the second radiator 150. The electric field of the second radiator 150 is mainly formed near the second side 112, and the electric field strength point is mainly formed near the current zero point. The second radiator 150 mainly transmits wireless signals through the first part 154 located on the second side 112.
[0135] In the electronic device control method of the embodiment of the present application, when the angle θ is within the first preset range, the electric field of the first radiator 140 can be formed near the first side 111, and the electric field of the second radiator 150 can be formed near the second side 112. Since the second side 112 is far away from the first side 111 and the third side 113 when the angle θ is within the first preset range, the electric field radiation area of the second radiator 150 is not in the same area as the electric field radiation area of the first radiator 140, thereby improving the isolation between the first radiator 140 and the second radiator 150, and the interference between the second radiator 150 and the first radiator 140 is small.
[0136] Please combine Figure 7 Please also refer to Fig. 20 , Fig. 20 A second flow chart of the electronic device control method provided in the embodiment of the present application. The electronic device 10 in the embodiment of the present application may further include a second regulating circuit 600. The second regulating circuit 600 may be electrically connected to the second portion 155 of the second radiator 150. A second electrical connection point 157 may be provided on the second portion 155 of the second radiator 150, and one end of the second regulating circuit 600 may be electrically connected to the second electrical connection point 157. Based on this, Fig. 20 As shown, the electronic device control method of the embodiment of the present application includes:
[0137] 101. Get the angle θ.
[0138] 103. When the angle θ is within a second preset range, control the second regulating circuit to operate so that the current density of the second radiator distributed in the second part is greater than the current density distributed in the first part.
[0139] The electronic device 10 may be provided with a sensor on the foldable body 100 to detect the angle θ. The specific working method of the sensor can refer to the above description, which will not be repeated here.
[0140] It can be understood that the second preset range can be an angle θ of 180 degrees. At this time, the foldable body 100 can be in an unfolded state, the first side 111 and the third side 113 are far away from each other and the distance is the farthest, and the interference between the first radiator 140 located on the first side 111 and the second radiator 150 located on the third side 113 is minimal.
[0141] It can be understood that the second preset range can be that the angle θ can also be 150 degrees to 180 degrees, 180 degrees to 210 degrees. At this time, the distance between the first side 111 and the third side 113 is also closer, and the interference between the first radiator 140 located on the first side 111 and the second radiator 150 located on the third side 113 is relatively small.
[0142] When the angle θ is within the second preset range, the first radiator 140 located on the first side 111 can be away from the second radiator 150 located on the third side 113, and the second regulating circuit 600 can form the current zero point of the second radiator 150 on the second portion 155 located on the third side 113, and can make the current density distributed in the second portion 155 greater than the current density distributed in the first portion 154. At this time, the current is mainly concentrated on the second portion 155 of the second radiator 150, and a small part is concentrated on the first portion 154 of the second radiator 150. The electric field of the second radiator 150 is mainly formed near the third side 113, and the electric field strength point of the second radiator 150 is mainly formed near the current zero point. The second radiator 150 mainly transmits wireless signals through the second portion 155 located on the third side 113.
[0143] In the electronic device control method of the embodiment of the present application, when the angle θ is within the second preset range, the electric field of the first radiator 140 can be formed near the first side 111, and the electric field of the second radiator 150 can be formed near the third side 113. Since the first side 111 and the third side 113 are far away from each other when the foldable body 100 is in the unfolded state, the electric field radiation area of the second radiator 150 and the electric field radiation area of the first radiator 140 are also far away from each other, the isolation between the first radiator 140 and the second radiator 150 is large, and the interference between the second radiator 150 and the first radiator 140 is small. In addition, in the electronic device 10 of the embodiment of the present application, the second adjustment circuit 600 is electrically connected to the second part 155 of the second radiator 150, and the second adjustment circuit 600 is more likely to change the capacitance and inductance values connected to the second part 155, so that the second adjustment circuit 600 is more likely to make the electric field strength point of the second radiator 150 formed at the second part 155.
