Technical Field

[0001] This application relates to the field of communication technology, and in particular to an electronic device and an antenna control method. Background Technology

[0002] With the development of communication technology, electronic devices such as smartphones can be folded or slid, allowing them to have unfolded, folded, or sliding forms. Furthermore, electronic devices can include antenna radiators to provide mobile communication services.

[0003] However, compared to the unfolded form, the surrounding environment of the antenna radiator changes adversely when the electronic device is in a folded or sliding form, resulting in a decrease in the radiation performance of the antenna radiator. Summary of the Invention

[0004] This application provides an electronic device and an antenna control method, which can have better antenna performance when the electronic device is in a folded state.

[0005] In a first aspect, this application provides an electronic device, comprising:

[0006] first ontology;

[0007] A first antenna is disposed on the first body, and the first antenna includes a first radiator and a first feed source;

[0008] The second body can move relative to the first body so that the electronic device is in an overlapping state where at least part of the second body overlaps with the first body, or in an unfolded state where the first body and the second body are far apart from each other.

[0009] A second antenna is disposed on the second body, and the second antenna includes a second radiator, a second feed, and an adjustment module; wherein...

[0010] In the deployed state, the first feed source excites the first radiator to support a first wireless signal, and the second feed source excites the second radiator to support a second wireless signal, wherein the second wireless signal is different from the first wireless signal;

[0011] In the overlapping state, at least a portion of the second radiator overlaps with the first radiator. The first feed source excites the first radiator to support the first wireless signal. Under the excitation of the first feed source, the second radiator is electromagnetically coupled to the first radiator and supports the third wireless signal. Under the action of the adjustment module, the third wireless signal is different from the first wireless signal.

[0012] Secondly, this application also provides an antenna control method applied to an electronic device, the electronic device including a first body, a first antenna disposed on the first body, a second body, and a second antenna disposed on the second body, the first antenna including a first radiator and a first feed, the second antenna including a second radiator, a second feed, and an adjustment module; the second body is movable relative to the first body, so that the electronic device is in an overlapping state where at least part of the second body overlaps with the first body, or in an unfolded state where the first body and the second body are far apart; in the overlapping state, at least part of the second radiator overlaps with the first radiator; wherein, the antenna control method includes:

[0013] When the electronic device is in the deployed state, the first feed source is controlled to excite the first radiator to support the first wireless signal, and the second feed source is controlled to excite the second radiator to support the second wireless signal, wherein the second wireless signal is different from the first wireless signal.

[0014] When the electronic device is in the overlapping state, the first feed source is controlled to excite the first radiator to support the first wireless signal, and the adjustment module is controlled to work and control the second radiator to electromagnetically couple with the first radiator under the excitation of the first feed source and support the third wireless signal, which is different from the first wireless signal.

[0015] The electronic device and antenna control method of this application allow the electronic device to support the transmission and reception of a first wireless signal when it is in an deployed state, and the second antenna to support the transmission and reception of a second wireless signal. The electronic device can support multiple wireless signals, making it applicable to a wider range of scenarios. When the electronic device is in an overlapping state, the first antenna can still support the transmission and reception of the first wireless signal. At this time, under the action of the adjustment module, the second radiator can be electromagnetically coupled with the first radiator under the excitation of the first feed source and support a third wireless signal different from the first wireless signal. The second radiator is less likely to affect the performance of the first antenna in supporting the first wireless signal, and the first antenna can also have better antenna performance in the overlapping state.

[0028] The following will refer to the appendices in the embodiments of this application. Figure 1 To be continued Figure 11 The technical solutions in the embodiments of this application are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] This application provides an electronic device, which can be a smartphone, tablet computer, or other similar device. It can also be a gaming device, augmented reality (AR) device, automotive device, data storage device, audio playback device, video playback device, laptop computer, desktop computing device, etc. The electronic device has wireless communication capabilities. For example, it can transmit Wireless Fidelity (Wi-Fi) signals, Global Positioning System (GPS) signals, 3rd Generation (3G), 4th Generation (4G), 5th Generation (5G), Near Field Communication (NFC) signals, Bluetooth (BT) signals, Ultra Wide Band (UWB) signals, etc.

[0030] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of a first structure of the electronic device 10 provided in an embodiment of this application. Figure 2 for Figure 1 The diagram shown illustrates the structure of the electronic device 10 in another state. Figure 3 for Figure 1 The diagram shows the structure of the first antenna 301 and the second antenna 302 of the electronic device 10. The electronic device 10 includes a first body 100, a second body 200, a first antenna 301, and a second antenna 302.

[0031] The first body 100 and the second body 200 can be folded or slid towards each other, so that the electronic device 10 can be in an unfolded or overlapped state. For example... Figure 1 As shown, the electronic device 10 can be in an unfolded state where the first body 100 and the second body 200 are far apart from each other; as Figure 2 As shown, the electronic device 10 can be in an overlapping state where at least part of the second body 200 overlaps with the first body 100. For example... Figures 1 to 3As shown, a first antenna 301 is disposed on a first body 100. The first antenna 301 includes a first radiator 310 and a first feed 320. The first feed 320 can be electrically connected to the first radiator 310 to feed a first excitation signal to the first radiator 310. A second antenna 302 is disposed on a second body 200. The second antenna 302 includes a second radiator 330, a second feed 340, and an adjustment module 350. The second feed 340 can be electrically connected to the second radiator 330 to feed a second excitation signal to the second radiator 330. The adjustment module 350 can be electrically connected to the second radiator 330 to adjust the radiation resonance mode of the second radiator 330. Wherein, as... Figure 1 As shown, in the deployed state, the first radiator 310 and the second radiator 330 are far apart. The first feed source 320 can excite the first radiator 310 to support a first wireless signal, and the second feed source 340 can excite the second radiator 330 to support a second wireless signal, which is different from the first wireless signal. Figure 2 As shown, in the overlapping state, at least part of the second radiator 330 can overlap with the first radiator 310. The first feed 320 can excite the first radiator 310 to work so that the first antenna 301 supports the first wireless signal. Furthermore, under the excitation of the first feed 320, the second radiator 330 is electromagnetically coupled to the first radiator 310 and supports the third wireless signal. At this time, under the action of the adjustment module 350, the third wireless signal is different from the first wireless signal.

[0032] It is understood that the first body 100 and the second body 200 can be thin plate-like or sheet-like structures, or hollow frame structures. The first body 100 and the second body 200 can 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, electronic components such as cameras, receivers, circuit boards with radio frequency circuits such as feed sources, and power supplies in the electronic device 10 can be mounted on the first body 100 and the second body 200 for fixation.

[0033] It is understandable that during folding or sliding operations, the first body 100 and the second body 200 can switch between an overlapping state and an unfolded state. For example... Figure 1 As shown, the first body 100 and the second body 200 can be deployed away from each other. In this state, the distance between the first antenna 301 on the first body 100 and the second antenna 302 on the second body 200 is relatively large. When the first antenna 301 and the second antenna 302 operate independently, they are less likely to interfere with each other. The antenna performance is also superior when the first antenna 301 supports the first wireless signal and the second antenna 302 supports the second wireless signal. For example... Figure 2As shown, the first body 100 and the second body 200 can also approach each other to an overlapping state. At this time, the distance between the first antenna 301 and the second antenna 302 is relatively close, and at least part of the second radiator 330 can overlap with the first radiator 310. The first radiator 310 of the first antenna 301 and the second radiator 330 of the second antenna 302 are prone to electromagnetic coupling connection. The first antenna 301 and the second antenna 302 are prone to mutual interference. The first antenna 301 is easily affected by the overlapping state, which causes the antenna performance to degrade.

[0034] To reduce the impact of overlapping states on the performance of the first antenna 301, the adjustment module 350 of the second antenna 302 in this embodiment can adjust the electrical length of the second radiator 330 to adjust the resonant mode of the second radiator 330. This makes the third wireless signal supported by the second radiator 330 after electromagnetic coupling with the first radiator 310 different from the first wireless signal supported by the first antenna 301. Therefore, the third wireless signal is less likely to affect the first wireless signal, and the first wireless signal can still have good radiation performance even in the overlapping state. Here, electrical length refers to the equivalent length of the radiator when radiating a signal, or the equivalent length required for electromagnetic wave transmission in the radiating structure. The electrical length of the radiator can be greater than, less than, or equal to its branch length. The adjustment module 350 may include a variable number of capacitors and inductors to allow the second radiator 330 to change its electrical length by electrically connecting circuits with different impedances, thereby making the third wireless signal different from the first wireless signal.

[0035] It is understandable that the frequency range of the third wireless signal can be completely separated from the frequency range of the first wireless signal in the spectrum, or the frequency range of the third wireless signal can partially overlap with the frequency range of the first wireless signal, but their center frequencies are different, so that the third wireless signal is different from the first wireless signal. For example, the first wireless signal can be a wireless signal in the B3 band (1710MHz-1880MHz), and the center frequency of the third wireless signal can be 2000MHz, with the frequency ranges of the third wireless signal being separated from the first wireless signal. Similarly, the frequency range of the second wireless signal can be completely separated from the frequency range of the first wireless signal, or the two can partially overlap with each other, but their center frequencies are different, so that the second wireless signal is different from the first wireless signal. For example, the first wireless signal can be a wireless signal in the mid-to-high frequency band (1000MHz to 3000MHz), and the second wireless signal can be a wireless signal in the low frequency band (less than 1000MHz).

[0036] Understandably, to further improve the antenna performance of the first wireless signal, the difference between the center frequency of the third wireless signal supported by the second radiator 330 and the center frequency of the first wireless signal in the overlapping state can be approximately 10% to 15% of the center frequency of the first wireless signal. This allows the third wireless signal supported by the second radiator 330 to further improve the antenna efficiency of the first wireless signal. For example, when the first wireless signal is in the B3 band, the center frequency of the third wireless signal can be 2000MHz. In this case, the antenna efficiency of the first wireless signal can be improved by 0.5dB compared to the antenna efficiency of the first wireless signal in the unfolded state, resulting in superior antenna performance for the first wireless signal.

[0037] It is understood that the first radiator 310 may support the first wireless signal in a quarter-wavelength mode, but is not limited to this. The first radiator 310 may include a first free end 311 and a first ground end 312, as well as a first feed point 313 disposed between the first free end 311 and the first ground end 312. The first feed source 320 is electrically connected to the first feed point 313, and the first ground end 312 is electrically connected to the ground system 360 to achieve grounding. The first feed source 320 may excite a resonant current to flow from the first ground end 312 to the first free end 311 on the first radiator 310, so that the first radiator 310 supports the first wireless signal. Of course, the first radiator 310 may also support the first wireless signal in other resonant modes, and this application embodiment does not limit this. The ground system 360 may be a plane or structure with zero potential, and the ground system 360 may form a common ground. The ground system 360 may be formed by conductors, printed circuits, or metal printed layers in the electronic device 10.

[0038] It is understood that the second radiator 330 may include a first end 331 and a second end 332, and a second feed point 333 disposed between the first end 331 and the second end 332. The second feed source 340 may be electrically connected to the second feed point 333, and the second radiator 330 may also be electrically connected to the ground system 360. The second radiator 330 may support the second wireless signal in a quarter-wavelength mode, but is not limited to this. Of course, the second radiator 330 may also support the second wireless signal in other modes, and this application embodiment does not limit this.

[0039] It is understandable that, such as Figure 1 and Figure 2 As shown, the electronic device 10 may also include, but is not limited to, a connecting structure 400 such as a hinge structure or a slide rail structure, so that the first body 100 and the second body 200 can be folded and slid relative to each other. The specific structure of the connecting structure 400, such as the hinge structure or the slide rail structure, can be found in the descriptions in related technologies and will not be detailed here.

[0040] In the embodiment of this application, when the electronic device 10 is in the unfolded state, the first antenna 301 can support the transmission and reception of the first wireless signal, and the second antenna 302 can support the transmission and reception of the second wireless signal. Thus, the electronic device 10 can support multiple wireless signals, and its application scenarios are more extensive. When the electronic device 10 is in the overlapping state, the first antenna 301 can still support the transmission and reception of the first wireless signal. At this time, under the action of the adjustment module 350, the second radiator 330 can be electromagnetically coupled with the first radiator 310 under the excitation of the first feed 320 and support a third wireless signal different from the first wireless signal. The second radiator 330 is less likely to affect the performance of the first antenna 301 in supporting the first wireless signal. Thus, the first antenna 301 can also have better antenna performance in the overlapping state.

[0041] When the electronic device 10 is in an overlapping state, the adjustment module 350 can also cause the second radiator 330 to electromagnetically couple with the first radiator 310 under the excitation of the second feed 340 and support third wireless signals of different frequency bands. At this time, based on the first wireless signal supported by the first radiator 310, a third wireless signal that is far from the frequency range of the first wireless signal (for example, the difference between the center frequency of the third wireless signal and the center frequency of the first wireless signal can be about 10% to 15% of the center frequency of the first wireless signal) and has better antenna efficiency in the frequency range of the first wireless signal can be selected from among the multiple third wireless signals supported by the second radiator 330. The electronic device 10 can control the adjustment module 350 to work according to the state of the adjustment module 350 corresponding to the third wireless signal, so that the third wireless signal supported by the second radiator 330 can not interfere with the first wireless signal and can also improve the antenna performance of the first wireless signal.

[0042] When the electronic device 10 is in the deployed state, the adjustment module 350 can also cause the second feed source 340 to excite the second radiator 330 to support second wireless signals of different frequency bands. Thus, in the deployed state, the second radiator 330 can support second wireless signals of more frequency bands; for example, the second radiator 330 can cover more low-frequency bands.

[0043] It should be noted that the adjustment module 350 can enable the second radiator 330 to support third wireless signals of different frequency bands in the overlapping state; or, the adjustment module 350 can enable the second feed 340 to excite the second radiator 330 to support second wireless signals of different frequency bands in the unfolded state; or, 350 can enable the second radiator 330 to support third wireless signals of different frequency bands in the overlapping state and can also enable the second feed 340 to excite the second radiator 330 to support second wireless signals of different frequency bands in the unfolded state. The embodiments of this application do not limit the function of the adjustment module 350.

[0044] Please refer to the following: Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of a second structure of the electronic device 10 provided in the embodiments of this application. Figure 5 for Figure 4 The diagram shows an electrical connection of the electronic device 10. The adjustment module 350 may include a first switching circuit 351.

[0045] The first switching circuit 351 includes a first switch 3511 and a first switching branch 3512. The first switch 3511 includes a first common terminal a1 and a first switching terminal b1. The first common terminal a1 is electrically connected to the second radiator 330. One end of the first switching branch 3512 is electrically connected to the first switching terminal b1, and the other end of the first switching branch 3512 is electrically connected to the second feed 340.

[0046] Understandably, in the deployed state, the first feed 320 can excite the first radiator 310 to support the first wireless signal. At this time, the first switch 3511 can connect the first common terminal a1 and the first switching terminal b1, so that the second feed 340 excites the second radiator 330 to support the second wireless signal. Thus, in the deployed state, the first antenna 301 and the second antenna 302 can work simultaneously, so that the first antenna 301 supports the first wireless signal and the second antenna 302 supports the second wireless signal.

[0047] Understandably, in the overlapping state, the first feed 320 can still excite the first radiator 310 to support the first wireless signal. At this time, the first switch 3511 can disconnect the connection between the first common terminal a1 and the first switching terminal b1 so that the second radiator 330 can electromagnetically couple with the first radiator 310 under the excitation of the first feed 320 and support the third wireless signal.

[0048] It is understood that the first switching branch 3512 may be, but is not limited to, an indefinite number of capacitors or inductors. The first switching branch 3512 may also serve as a matching structure to perform impedance matching adjustment on the second excitation signal provided by the second feed 340, so as to further improve the radiation performance of the second wireless signal supported by the second radiator 330 excited by the second feed 340.

[0049] The adjustment module 350 of this application embodiment includes a first switching circuit 351. Under the action of the first switching circuit 351, the first feed 320 can be connected to the second radiator 330 so that the second antenna 302 supports the second wireless signal in the unfolded state. The first feed 320 can also be disconnected from the second radiator 330 so that the second radiator 330 supports the third wireless signal in the unfolded state.

[0050] Please refer to the following: Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of a third structure of the electronic device 10 provided in the embodiments of this application. Figure 7 for Figure 6 The diagram shows an electrical connection of the electronic device 10. The adjustment module 350 may also include a second switching circuit 352.

[0051] One end of the second switching circuit 352 is electrically connected to the second radiator 330, and the other end of the second switching circuit 352 is grounded. The second switching circuit 352 includes a second switch 3521 and multiple (two or more) second switching branches 3522. The second switch 3521 includes a second common terminal a2 and multiple second switching terminals. The second common terminal a2 is electrically connected to the second radiator 330, one end of each second switching branch 3522 is electrically connected to a second switching terminal, and the other end of each second switching branch 3522 is grounded. For example, the second switching circuit 352 includes second switching branches 3522a, 3522b, 3522c, and 3522d; the second switch 3521 includes second switching terminals b21, b22, b23, and b24. Among them, one end of the second switching branch 3522a is electrically connected to the second switching terminal b21 and the other end is grounded; one end of the second switching branch 3522b is electrically connected to the second switching terminal b22 and the other end is grounded; one end of the second switching branch 3522c is electrically connected to the second switching terminal b23 and the other end is grounded; one end of the second switching branch 3522d is electrically connected to the second switching terminal b24 and the other end is grounded.

[0052] Understandably, in the overlapping state, the first switch 3511 is used to disconnect the connection between the first common terminal a1 and the first switching terminal b1, and the second switch 3521 is used to switch between conducting the second common terminal a2 and multiple second switching terminals, so that the second radiator 330 is electromagnetically coupled to the first radiator 310 under the excitation of the first feed source 320 and supports the third wireless signal of different frequency bands.

[0053] Understandably, in the deployed state, the first switch 3511 is used to connect the first common terminal a1 and the first switching terminal b1, and the second switch 3521 is used to switch between connecting the second common terminal a2 and the electrical connection of multiple second switching terminals, so that the second feed 340 excites the second radiator 330 to support second wireless signals of different frequency bands.

[0054] It is understood that each second switching branch 3522 may include a variable number of capacitors, inductors, and other components, and at least two second switching branches 3522 have different impedances, so that the at least two second switching branches 3522 can cause the second radiator 330 to have different electrical lengths. For example, as Figure 7As shown, the second switching circuit 352 includes four second switching branches 3522, of which two second switching branches 3522, such as second switching branch 3522b and second switching branch 3522c, include inductive load elements, another second switching branch 3522, such as second switching branch 3522a, includes capacitive load elements, and yet another second switching branch 3522, such as second switching branch 3522d, is directly grounded.

[0055] Understandably, one second switching branch 3522b of the second switching circuit 352 includes a first inductor, one end of which is electrically connected to a second switching terminal b22 and the other end is grounded; another second switching branch 3522c includes a second inductor, one end of which is electrically connected to a second switching terminal b23 and the other end is grounded; yet another second switching branch 3522a includes a first capacitor, one end of which is electrically connected to a second switching terminal b21 and the other end is grounded; and the last second switching branch 3522d has one end electrically connected to a second switching terminal b24 and the other end directly grounded. The inductance value of the second inductor may differ from the inductance value of the first inductor, so that when the second common terminal a2 of the second switch 3521 is connected to different second switching terminals, the second radiator 330 can support second wireless signals of different frequency bands.

[0056] For example, when the second switch 3521 connects the second common terminal a2 and the second switching terminal b21, grounding the first capacitor element, the second radiator 330 can support a second wireless signal in a frequency band, such as, but not limited to, the B8 band (880MHz-960MHz) or the N8 band (880MHz-960MHz). When the second switch 3521 connects the second common terminal a2 and the second switching terminal b24, directly grounding the second switching branch 3522d, the second radiator 330 can support a second wireless signal in a frequency band, such as, but not limited to, the B5 band (824MHz-894MHz) or the N5 band (824MHz-894MHz). When the second switch 3521 connects the second common terminal a2 and the second switching terminal b22, directly grounding the first inductor element, the second radiator 330 can support a second wireless signal in a frequency band, such as, but not limited to, the B10 band (791MHz-862MHz) or the N20 band (791MHz-862MHz). When the second switch 3521 connects the second common terminal a2 and the second switching terminal b23, causing the second inductor to be directly grounded, the second radiator 330 can support a second wireless signal in a frequency band, such as, but not limited to, the b18 band (703MHz to 803MHz) or the N28 band (703MHz to 803MHz). When the second switch 3521 connects the second common terminal a2 and all the second switching terminals, the second radiator 330 can support a second wireless signal in a frequency band, such as, but not limited to, the B71 band (617MHz-698MHz) or the N71 band (617MHz-698MHz).

[0057] It is understood that the frequency band covered by the second wireless signal may include bands B71, B28, B20, B5, B8, N71, N28, N20, N5, or N8. Therefore, under the action of the second switching circuit 352, the second antenna 302, in its deployed state, can support second wireless signals in bands B71, B18, B10, B5, B8, N71, N28, N20, N5, or N8. The second antenna 302, in its deployed state, can support second wireless signals in multiple low-frequency bands, and can cover more low-frequency bands. Of course, under the action of the second switching circuit 352, the second antenna 302, in its deployed state, can also support second wireless signals in other frequency bands, such as, but not limited to, mid-high frequency and high frequency bands. This embodiment of the application does not limit the frequency bands of the second wireless signals supported by the second antenna 302.

[0058] It should be noted that the above is only an exemplary description of the operation of the second switching circuit 352. The second switching circuit 352 can also switch between second wireless signals of different frequency bands and third wireless signals of different frequency bands through other switching methods. Of course, the second switching circuit 352 can also have other structures, such as, but not limited to, including more second switching branches 3522. The specific structure and specific operation of the second switching circuit 352 are not limited in the embodiments of this application.

[0059] It is understood that the second switch 3521 can be a multi-pole multi-throw switch, or the second switch 3521 can be a switch network. The second switch 3521 can conduct one second switching branch 3522 to ground, or the second switch 3521 can conduct multiple second switching branches 3522 to ground. The specific structure of the second switch 3521 is not limited in the embodiments of this application.

[0060] The adjustment module 350 of this application embodiment includes a second switching circuit 352. Under the switching of the second switching circuit 352, the second antenna 302 can support more frequency bands of second wireless signals, and the second antenna 302 can also support more frequency bands of third wireless signals. Thus, the second antenna 302 can be applied to more communication scenarios, and the application scenarios of the electronic device 10 are also more extensive.

[0061] Among them, such as Figure 7 As shown, the first switching circuit 351 may further include a fourth switching branch 3514 and at least one third switching branch 3513; the first switch 3511 may further include at least one third switching terminal, such as third switching terminal b31, third switching terminal b32 and third switching terminal b33.

[0062] One end of each third switching branch 3513 is electrically connected to a third switching terminal, and the other end of each third switching branch 3513 is grounded. One end of the fourth switching branch 3514 is electrically connected between the first common terminal a1 and the second radiator 330, and the other end of the fourth switching branch 3514 is grounded.

[0063] Understandably, in the deployed state, the first switch 3511 can connect the first common terminal a1 and the first switching terminal b1, and the second switch 3521 is used to switch between connecting the second common terminal a2 and multiple second switching terminals, so that the second feed 340 excites the second radiator 330 to support second wireless signals of different frequency bands.

[0064] Understandably, in the overlapping state, the first switch 3511 can disconnect the connection between the first common terminal a1 and the first switching terminal b1, the second switch 3521 can connect or disconnect the second common terminal a2 with at least one second switching terminal, and the first switch 3511 can also connect or disconnect the electrical connection between the first common terminal a1 and at least one third switching terminal, so that the second radiator 330 is electromagnetically coupled to the first radiator 310 under the excitation of the first feed source 320 and supports a third wireless signal different from the first wireless signal.

[0065] It is understood that the first switching branch 3512, the third switching branch 3513, or the fourth switching branch 3514 of the first switching circuit 351 may include a variable number of capacitors and inductors. For example, the first switching branch 3512 may include an inductive load element or a capacitive load element, the fourth switching branch 3514 may include an inductive load element, and the third switching branch 3513 may include an inductive load element, a capacitive load element, or other elements. Figure 7 As shown, the first switching circuit 351 includes three third switching branches 3513, such as third switching branch 3513a, third switching branch 3513b, and third switching branch 3513c. One of the third switching branches 3513a includes an inductive load element, such as a third inductor element. One end of the third inductor element can be electrically connected to a third switching terminal b31, and the other end of the third inductor element can be grounded. Another third switching branch 3513b includes a capacitive load element, such as a second capacitor element. One end of the second capacitor element can be electrically connected to a third switching terminal b32, and the other end of the second capacitor element can be grounded. Yet another third switching branch 3513c is directly grounded.

[0066] The switching state of the first switching circuit 351 and the second switching circuit 352 can be controlled according to the frequency range of the first wireless signal supported by the first radiator 310, so that the second radiator 330 can support the third wireless signal of a suitable frequency band under the joint action of the first switching circuit 351 and the second switching circuit 352, so as to avoid the third wireless signal from interfering with the first wireless signal and to make the first wireless signal have better antenna efficiency.

[0067] For example, please combine Figure 7 Please refer to Figure 8 , Figure 8 This is a schematic diagram of the S-parameter curves of the electronic device 10 in this application embodiment when it supports wireless signals of different frequency bands. In the overlapping state, when the first antenna 301 supports the B3 frequency band, under the switching action of the first switching circuit 351 and the second switching circuit 352, the second radiator 330 is electromagnetically coupled to the first radiator 310 under the excitation of the first feed 320 and can support the third wireless signal of different frequency bands.

[0068] Curve S1 represents the S-parameter curve of the first radiator 310 and the second radiator 330 supporting a certain frequency band of wireless signal when the second switch 3521 of the second switching circuit 352 disconnects the electrical connection between the second common terminal a2 and all switching terminals, and the first switch 3511 of the first switching circuit 351 disconnects the electrical connection between the first common terminal a1 and all switching terminals, under the excitation of the first feed source 320. Figure 8 As can be seen from region A1, the frequency of the wireless signal supported by the second radiator 330 is close to that of the first wireless signal (B3 band signal) supported by the first radiator 310, resulting in an efficiency dip within the frequency range of the first wireless signal. This efficiency dip can affect the antenna efficiency of the first wireless signal.

[0069] Curve S2 is the S-parameter curve of the second switch 3521 of the second switching circuit 352 grounded through at least one second switching branch 3522 and the first switch 3511 of the first switching circuit 351 disconnected from the first common terminal a1 and all switching terminals in the overlapping state. Under the excitation of the first feed 320, the first radiator 310 and the second radiator 330 support a wireless signal of another frequency band (e.g., a third wireless signal of a certain frequency band). As can be seen from region A2, at this time, the frequency range of the third wireless signal supported by the second radiator 330 does not fall within the frequency range of the first wireless signal supported by the first radiator 310, and the third wireless signal supported by the second radiator 330 is unlikely to affect the first wireless signal.

[0070] Curves S3 and S4 are S-parameter curves of the second switch 3521 of the second switching circuit 352 grounded through at least one second switching branch 3522 and the first common terminal a1 of the first switch 3511 of the first switching circuit 351 conducting the third inductor and the second capacitor respectively, when the first radiator 310 and the second radiator 330 support a wireless signal of another frequency band (e.g., a third wireless signal of another frequency band) under the excitation of the first feed 320. As can be seen from region A3, the frequency range of the third wireless signal supported by the second radiator 330 does not fall within the frequency range of the first wireless signal supported by the first radiator 310, and the third wireless signal supported by the second radiator 330 is unlikely to affect the first wireless signal.

[0071] Curve S5 is the S-parameter curve of the first radiator 310 and the second radiator 330 supporting the wireless signal under the excitation of the first feed 320 when the second switch 3521 of the second switching circuit 352 is grounded through at least one second switching branch 3522 and the first switch 3511 of the first switching circuit 351 is grounded through the third switching branch 3513c. As can be seen from region A4, at this time the frequency range of the third wireless signal supported by the second radiator 330 does not fall within the frequency range of the first wireless signal supported by the first radiator 310, and the third wireless signal supported by the second radiator 330 is unlikely to affect the first wireless signal.

[0072] according to Figure 8 The multiple curves shown can be used to analyze the efficiency of the second radiator 330 under different states of the first switching circuit 351 and the second switching circuit 352, based on the first wireless signal supported by the first antenna 301 in the B3 band. Using the frequency band range covered by the first wireless signal (e.g., the B3 band range) as a benchmark, the states of the first switching circuit 351 and the second switching circuit 352 corresponding to the curves where the efficiency dips of the second radiator 330 under different switching circuits are far from the frequency band range of the first wireless signal and where the efficiency is highest within the frequency band range covered by the first wireless signal (e.g., the B3 band range) can represent the optimal switching circuit state for the second radiator 330 under the current first wireless signal. For example, comparing... Figure 8 The frequency range of regions A2 to A4 and the antenna efficiency of each region within the frequency band covered by the first wireless signal (e.g., the B3 band) can be controlled by selecting the switching state of the second switching circuit 352 and the first switching circuit 351 corresponding to region A3. This ensures that the third wireless signal supported by the second radiator 330 not only does not interfere with the first wireless signal, but also has high antenna efficiency within the frequency band covered by the first wireless signal (e.g., the B3 band). Furthermore, even under the switching state of the second switching circuit 352 and the first switching circuit 351 corresponding to region A3, the third wireless signal can further enhance the antenna performance of the first wireless signal.

[0073] It is understood that the first switch 3511 of the first switching circuit 351 can be a multi-pole multi-throw switch, or the first switch 3511 can be a switch network. The first switch 3511 can conduct one third switching branch 3513 to ground, or the first switch 3511 can conduct multiple third switching branches 3513 to ground. The specific structure of the first switch 3511 is not limited in the embodiments of this application.

[0074] It is understandable that when the first wireless signal is in a different frequency range, the electronic device 10 can control the first switching circuit 351 and the second switching circuit 352 to select different switching states, so that the third wireless signal supported by the second radiator 330 under the action of the first switching circuit 351 and the second switching circuit 352 is different from the first wireless signal at this time.

[0075] It is understood that the first wireless signal may be, but is not limited to, a mid-to-high frequency wireless signal. Under the action of the second switching circuit 352 and the first switching circuit 351, the third wireless signal supported by the second radiator 330 can cover a frequency band range of 1.5GHz to 4GHz. The third wireless signal can cover a wider frequency band range, so that when the first wireless signal is a different mid-to-high frequency wireless signal, the second switching circuit 352 and the first switching circuit 351 have a corresponding switching state, so that the third wireless signal is different from the first wireless signal.

[0076] It is understood that the first switching circuit 351 can be electrically connected to the second switching circuit 352 in different regions of the second radiator 330. For example, the second radiator 330 includes a first electrical connection point 334 and a second electrical connection point 335 disposed between the first end 331 and the second end 332. The first electrical connection point 334 can be disposed near the first end 331 (for example, the distance between the first electrical connection point 334 and the first end 331 can be less than or equal to one-sixteenth of the branch length of the second radiator 330), and the second electrical connection point 335 can be disposed near the second end 332 (for example, the distance between the second electrical connection point 335 and the second end 332 can be less than or equal to one-sixteenth of the branch length of the second radiator 330). The first common terminal a1 of the first switching circuit 351 can be electrically connected to the first electrical connection point 334, and the second common terminal a2 of the second switching circuit 352 can be electrically connected to the second electrical connection point 335. At this time, the second switching circuit 352 and the first switching circuit 351 can adjust the electrical length of the entire second radiator 330, and the second switching circuit 352 and the first switching circuit 351 can adjust a wider frequency range.

[0077] It is understandable that since the first switching branch 3512 of the first switching circuit 351 is electrically connected to the second feed source 340, the first switching circuit 351 can also be electrically connected to the second feed point 333 of the second radiator 330. At this time, the first electrical connection point 334 can overlap with the second feed point 333, and the second feed source 340 can be electrically connected to the second radiator 330 through the first switching circuit 351.

[0078] It is understood that the second switching circuit 352 and the first switching circuit 351 of this application can be arbitrarily combined to form a variety of switching states (for example, the two switching circuits of this application can be combined to form more than 20 switching states), so that under the action of the second switching circuit 352 and the first switching circuit 351, the second radiator 330 can support second wireless signals of different frequency bands under the action of the second feed 340, and the second radiator 330 can also support third wireless signals of different frequency bands than the first wireless signal under the action of the first feed 320.

[0079] It should be noted that the above is merely an exemplary description of the second switching circuit 352 and the first switching circuit 351 in this application embodiment. The second switching circuit 352 and the first switching circuit 351 can also have other structures, such as, but not limited to, including more switching branches. This application embodiment does not limit the specific structure of the second switching circuit 352 and the first switching circuit 351. Similarly, the adjustment module 350 of this application can also include other structures, such as, but not limited to, including more or fewer switching circuits. This application embodiment also does not limit the specific structure of the adjustment module 350.

[0080] In the embodiment of this application, when the first wireless signal supported by the first radiator 310 is a mid-to-high frequency signal and the second wireless signal supported by the second radiator 330 is a low-frequency signal, the electronic device 10 can achieve a layout where the mid-to-high frequency antenna and the opposite low-frequency antenna are designed together. Furthermore, under the action of the second switching circuit 352 and the first switching circuit 351, the second radiator 330 can support low-frequency signals of different frequency bands in the unfolded state, and the interference between the third wireless signal supported by the second radiator 330 and the first wireless signal supported by the first radiator 310 is small in the overlapping state. Thus, through the reasonable combination of the two switching circuits, the second radiator 330 can take into account both low-frequency antennas and mid-to-high frequency antennas, and the antenna performance of the electronic device 10 is better.

[0081] Please refer to this again. Figure 6 and Figure 7 The electronic device 10 may also include a matching circuit 370, which may be electrically connected between the first feed 320 and the first radiator 310. The matching circuit 370 may adjust the impedance of the excitation signal provided by the first feed 320 to improve the antenna performance of the first radiator 310 in supporting the first wireless signal.

[0082] It is understood that the matching circuit 370 may include, but is not limited to, an indefinite number of capacitors and inductors, and the embodiments of this application do not limit this.

[0083] Please refer to the following: Figure 9 , Figure 9This is a schematic diagram of a third structure of the electronic device 10 provided in an embodiment of this application. The first body 100 may further include a first border 110, and the second body 200 may further include a second border 210.

[0084] The first frame 110 can be the outer frame of the first body 100, and the second frame 210 can be the outer frame of the second body 200. The first frame 110 and the second frame 210 can be made of a conductive material and have a certain rigidity. The first frame 110 and the second frame 210 can provide support for electronic devices or components in the electronic device 10. For example... Figure 9 As shown, the first frame 110 can form a first metal branch 112 by opening a first gap 111, and the first radiator 310 can include the first metal branch 112; the second frame 210 can also form a second metal branch 212 by opening a second gap 211, and the second radiator 330 can include the second metal branch 212; thus, the first radiator 310 and the second radiator 330 can be metal frame radiators. In the overlapping state, at least a portion of the second metal branch 212 can overlap with the first metal branch 112, so that at least a portion of the second radiator 330 can overlap with the first radiator 310.

[0085] It is understood that at least one of the first radiator 310 and the second radiator 330 may not be a metal-framed radiator. For example, the first radiator 310 may be connected to the first frame 110, and the second radiator 330 may be connected to the second frame 210.

[0086] It is understood that the first radiator 310 and the second radiator 330 may also be, but are not limited to, flexible circuit board radiators, printed circuit board radiators, laser direct forming radiators, silver paste spraying radiators, etc. The specific structure of the first radiator 310 and the second radiator 330 is not limited in the embodiments of this application.

[0087] It is understood that the electronic device 10 may fill the space between the first gap 111 and the second gap 211 with a non-conductive material to increase the structural strength of the first frame 110 and the second frame 210.

[0088] In the electronic device 10 of this application embodiment, the first frame 110 and the second frame 210 form a first radiator 310 and a second radiator 330 through a slit. The first radiator 310 and the second radiator 330 do not need to occupy additional space in the electronic device 10, and the electronic device 10 can achieve a miniaturized design.

[0089] Please refer to this again. Figure 9The first body 100 may further include a first intermediate plate 120, and the second body 200 may further include a second intermediate plate 220. The first intermediate plate 120 and the second intermediate plate 220 may be thin plates or sheet-like structures to provide support for electronic devices or functional components in the electronic device 10. The first frame 110 may be arranged around the edge of the first intermediate plate 120, and the second frame 210 may be arranged around the edge of the first intermediate plate 120.

[0090] It is understood that at least one of the first intermediate plate 120 and the second intermediate plate 220 may be provided with a ground system 360, so that the first radiator 310 provided on the first body 100 can be electrically connected to the ground system 360 on the first body 100 to achieve grounding, and the second radiator 330 provided on the second body 200 can be electrically connected to the ground system 360 on the second body 200 to achieve grounding.

[0091] Please refer to this again. Figure 9 The electronic device 10 may also include a flexible display screen 500, a circuit board 600, and a power supply 700.

[0092] The flexible display screen 500 can form the display surface of the electronic device 10 for displaying images, text, and other information. The flexible display screen 500 can include displays of the type such as a Liquid Crystal Display (LCD) or an Organic Light-Emitting Diode (OLED). The flexible display screen 500 can be connected to the first body 100 and the second body 200, and can be folded along with the folding of the first body 100 and the second body 200.

[0093] For example, one end of the flexible display screen 500 can be connected to the first body 100, and the other end of the flexible display screen 500 can be connected to the second body 200. When the first body 100 and the second body 200 are in an unfolded state, the two ends of the flexible display screen 500 can be on the same plane as the first body 100 and the second body 200 are unfolded, and the flexible display screen 500 is in an unfolded state. When the first body 100 and the second body 200 are in an overlapping state, the flexible display screen 500 can be folded as the first body 100 and the second body 200 are folded, so that the two ends of the flexible display screen 500 can be close to each other or completely close to each other and folded together.

[0094] The circuit board 600 can be mounted on either the first body 100 or the second body 200, and can serve as the motherboard of the electronic device 10. The circuit board 600 can integrate a processor, and may also integrate one or more functional components such as a headphone jack, an accelerometer, a gyroscope, and a motor. The flexible display screen 500, the first feed source 320, the second feed source 340, the second switching circuit 352, the first switching circuit 351, and the matching circuit 370 can be located on the circuit board 600 for control by the processor on the circuit board 600.

[0095] The power supply 700 can be installed on either the first body 100 or the second body 200. Simultaneously, the power supply 700 can be electrically connected to the circuit board 600 to power the electronic device 10. The circuit board 600 may be equipped with a power management circuit. The power management circuit is used to distribute the voltage provided by the power supply 700 to the various electronic components in the electronic device 10.

[0096] It is understood that the above are merely exemplary examples of the electronic device 10. The electronic device 10 in this application embodiment may also include components such as a camera, a sensor, and a sound-to-electric conversion device. These components can be found in the descriptions in related technologies and will not be repeated here.

[0097] Based on the structure of the electronic device 10 described above, this application also provides an antenna control method applicable to the electronic device 10 in any of the above embodiments. The electronic device 10 includes a first body 100, a first antenna 301 disposed on the first body 100, a second body 200, and a second antenna 302 disposed on the second body 200. The first antenna 301 includes a first radiator 310 and a first feed 320, and the second antenna 302 includes a second radiator 330, a second feed 340, and an adjustment module 350. The second body 200 can move relative to the first body 100, so that the electronic device 10 is in an overlapping state where at least a portion of the second body 200 overlaps with the first body 100, or in an deployed state where the first body 100 and the second body 200 are far apart. In the overlapping state, at least a portion of the second radiator 330 can overlap with the first radiator 310. (See reference...) Figure 10 , Figure 10 This is a schematic flowchart of a first embodiment of the antenna control method provided in this application. The antenna control method includes:

[0098] In 101, when the electronic device 10 is in the deployed state, the first feed source 320 is controlled to excite the first radiator 310 to support the first wireless signal, and the second feed source 340 is controlled to excite the second radiator 330 to support the second wireless signal, the second wireless signal being different from the first wireless signal.

[0099] In the deployed state, the first feed source 320 and the second feed source 340 can be controlled to operate. The first feed source 320 can feed a first excitation signal to the first radiator 310 to excite the first radiator 310 to support the first wireless signal, and the second feed source 340 can feed a second excitation signal to the second radiator 330 to excite the second radiator 330 to support the second wireless signal.

[0100] It is understood that the first wireless signal may be, but is not limited to, a mid-to-high frequency wireless signal, and the second wireless signal may be, but is not limited to, a low-frequency wireless signal. Therefore, the electronic device 10 of this application can implement a scheme where the mid-to-high frequency antenna and the opposite low-frequency antenna are designed together.

[0101] In 102, when the electronic device 10 is in an overlapping state, the first feed source 320 is controlled to excite the first radiator 310 to support the first wireless signal, and the control adjustment module 350 is controlled to work and control the second radiator 330 to electromagnetically couple with the first radiator 310 under the excitation of the first feed source 320 and support the third wireless signal, which is different from the first wireless signal.

[0102] In the overlapping state, the first feed source 320 can be controlled to work while the second feed source 340 is controlled to not work. At this time, the first feed source 320 can feed the first excitation signal to the first radiator 310 to excite the first radiator 310 to support the first wireless signal. Under the excitation of the first feed source 320, the second radiator 330 can be electromagnetically coupled with the first radiator 310 to support the third wireless signal. Under the adjustment of the adjustment module 350, the third wireless signal supported by the second radiator 330 can be different from the first wireless signal.

[0103] It is understood that in some embodiments, before step 101, the antenna control method may further include: determining the current state of the electronic device 10. In this case, please refer to... Figure 11 , Figure 11 This is a second flowchart illustrating the antenna control method provided in an embodiment of this application. The antenna control method may further include:

[0104] In step 201, the current state of electronic device 10 is determined;

[0105] In 202, when the electronic device 10 is in the deployed state, the first feed source 320 is controlled to excite the first radiator 310 to support the first wireless signal, and the second feed source 340 is controlled to excite the second radiator 330 to support the second wireless signal. The second wireless signal is different from the first wireless signal.

[0106] In step 203, when the electronic device 10 is in an overlapping state, the first feed source 320 is controlled to excite the first radiator 310 to support the first wireless signal, and the control adjustment module 350 is controlled to work and control the second radiator 330 to electromagnetically couple with the first radiator 310 under the excitation of the first feed source 320 and support the third wireless signal, which is different from the first wireless signal.

[0107] It is understood that the electronic device 10 may be equipped with a variety of attitude sensors, such as, but not limited to, gyroscopes, three-axis sensors, five-axis sensors, proximity sensors, etc. Multiple attitude sensors may be set in different areas of the electronic device 10 to detect whether the current state of the electronic device 10 is an unfolded state or an overlapped state.

[0108] Understandably, the current state of the electronic device 10 can be obtained by detecting the state of the connecting structure 400, such as the hinge. For example, when the electronic device 10 includes a hinge, the electronic device 10 can obtain the opening and closing angle of the hinge. If the opening and closing angle of the hinge is within a preset angle range (e.g., but not limited to, the opening and closing angle of the hinge being less than or equal to 60 degrees), it is determined that the electronic device 10 is in an overlapping state; if the opening and closing angle of the hinge is not within the preset angle range, it is determined that the electronic device 10 is in an unfolded state.

[0109] Understandably, the current state of the electronic device 10 can also be obtained by detecting the bending angle of the flexible display screen 500. For example, if the bending angle of the flexible display screen 500 is within a preset angle range (e.g., but not limited to, the opening and closing angle of the hinge being less than or equal to 60 degrees), it is determined that the electronic device 10 is in an overlapping state; if the bending angle of the flexible display screen 500 is not within the preset angle range, it is determined that the electronic device 10 is in an unfolded state.

[0110] It should be noted that the antenna control method of this application can also obtain the current state of the electronic device 10 in other ways, and the embodiments of this application do not limit this.

[0111] In the deployed state, the first feed source 320 and the second feed source 340 can be controlled to operate. The first feed source 320 can feed a first excitation signal to the first radiator 310 to excite the first radiator 310 to support the first wireless signal, and the second feed source 340 can feed a second excitation signal to the second radiator 330 to excite the second radiator 330 to support the second wireless signal.

[0112] In the overlapping state, the first feed source 320 can be controlled to work while the second feed source 340 is controlled to not work. At this time, the first feed source 320 can feed the first excitation signal to the first radiator 310 to excite the first radiator 310 to support the first wireless signal. Under the excitation of the first feed source 320, the second radiator 330 can be electromagnetically coupled with the first radiator 310 to support the third wireless signal. Under the adjustment of the adjustment module 350, the third wireless signal supported by the second radiator 330 can be different from the first wireless signal.

[0113] It is understood that, in some embodiments, the antenna control method may further include: when the electronic device 10 is in an deployed state, controlling the adjustment module 350 to operate so that the second feed 340 excites the second radiator 330 to support a second wireless signal of a different frequency band; and / or, when the electronic device 10 is in an overlapped state, controlling the adjustment module 350 to operate so that the second radiator 330, under the excitation of the first feed 320, is electromagnetically coupled to the first radiator 310 and supports a third wireless signal of a different frequency band.

[0114] It is understood that, in some embodiments, the adjustment module 350 may include a first switching circuit 351 and a second switching circuit 352. The first switching circuit 351 includes a first switch 3511, a first switching branch 3512, a fourth switching branch 3514, and at least one third switching branch 3513. The first switch 3511 includes a first common terminal a1, a first switching terminal b1, and at least one third switching terminal. The first common terminal a1 is electrically connected to the second radiator 330. One end of the first switching branch 3512 is electrically connected to the first switching terminal b1, and the other end of the first switching branch 3512 is electrically connected to the second feed 340. One end of each third switching branch 3513 is electrically connected to a third switching terminal, and the other end of each third switching circuit is grounded. One end of the fourth switching branch 3514 is electrically connected between the second common terminal a2 and the second radiator 330, and the other end of the fourth switching branch 3514 is grounded. The second switching circuit 352 includes a second switch 3521 and a plurality of second switching branches 3522. The second switch 3521 includes a second common terminal a2 and a plurality of second switching terminals. The second common terminal a2 is electrically connected to the second radiator 330. One end of each second switching branch 3522 is electrically connected to a second switching terminal, and the other end of each second switching branch 3522 is grounded.

[0115] In step 102, when the electronic device 10 is in the deployed state, controlling the second feed source 340 to excite the second radiator 330 to support the second wireless signal includes: when the electronic device 10 is in the deployed state, controlling the first switch 3511 to conduct the first common terminal a1 and the first switching terminal b1, and controlling the second switch 3521 to switch between conducting the second common terminal a2 and multiple second switching terminals, so that the second feed source 340 excites the second radiator 330 to support the second wireless signal of different frequency bands.

[0116] In step 103, when the electronic device 10 is in an overlapping state, the control adjustment module 350 operates and controls the second radiator 330 to electromagnetically couple with the first radiator 310 under the excitation of the first feed source 320 and support the third wireless signal. This includes: when the electronic device 10 is in an overlapping state, controlling the first switch 3511 to disconnect the connection between the first common terminal a1 and the first switching terminal b1, controlling the second switch 3521 to conduct or disconnect the connection between the second common terminal a2 and at least one second switching terminal, and controlling the first switch 3511 to conduct or disconnect the electrical connection between the first common terminal a1 and at least one third switching terminal, so that the second radiator 330 electromagnetically couples with the first radiator 310 under the excitation of the first feed source 320 and supports the third wireless signal, which is different from the first wireless signal.

[0117] It is understood that the switching states of the second switching circuit 352 and the first switching circuit 351 can be controlled according to the frequency range of the first wireless signal supported by the first radiator 310, so that the second radiator 330 can support the third wireless signal in a suitable frequency band under the joint action of the second switching circuit 352 and the first switching circuit 351, so as to avoid the third wireless signal interfering with the first wireless signal.

[0118] It is understandable that when the first wireless signal is in a different frequency range, the second switching circuit 352 and the first switching circuit 351 can be controlled to select different switching states so that the third wireless signal supported by the second radiator 330 under the action of the second switching circuit 352 and the first switching circuit 351 is different from the first wireless signal at this time.

[0119] In the antenna control method of this application, when the electronic device 10 is in the deployed state, the first feed 320 can be controlled to excite the first radiator 310 to support the transmission and reception of the first wireless signal, and the second feed 340 can be controlled to excite the second radiator 330 to support the transmission and reception of the second wireless signal. Thus, the electronic device 10 can support multiple wireless signals, and the electronic device 10 is applicable to a wider range of scenarios. At the same time, when the electronic device 10 is in the overlapping state, the first feed 320 can be controlled to excite the first radiator 310 to support the transmission and reception of the first wireless signal. At this time, under the action of the adjustment module 350, the second radiator 330 can be electromagnetically coupled with the first radiator 310 under the excitation of the first feed 320 and support a third wireless signal different from the first wireless signal. The second radiator 330 is less likely to affect the performance of the first antenna 301 in supporting the first wireless signal, so the first antenna 301 can also have better antenna performance in the overlapping state.

Content not described in the antenna control method embodiments can be found in the descriptions of the electronic device 10 embodiments, and vice versa.
