[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are 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 ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] See also Figure 1 , which is a schematic diagram of a head-mounted electronic device according to an embodiment of the present application. The head-mounted electronic device 100 may include: a frame 110 , temples 120 , an antenna array 130 , and a first controller 140 .

[0026] In this embodiment, the temple 120 can be connected to the frame 110. The temple 120 can be folded and unfolded, so the state of the temple 120 can include a folded state and an unfolded state. That is, the state of the temple 120 can include an unfolded state when the temple is fully unfolded and a folded state when the temple is folded relative to the frame. The antenna array 130 can include a plurality of antenna elements, wherein each antenna element can be arranged on at least one of the temple 120 and the frame 110. Each antenna element in the antenna array 130 can enable the head-mounted electronic device to achieve wireless communication connection.

[0027] In this embodiment, the first controller 140 may be electrically connected to at least one antenna element 131 among the plurality of antenna elements. The first controller 140 may be used to control the at least one antenna element 131 to work when the temple 120 is in the unfolded state, and to control the at least one antenna element 131 to stop working when the temple 120 is in the folded state. It should be noted that the first controller 140 controlling the at least one antenna element 131 to stop working may be that the first controller 140 controls the feeding power supply of the at least one antenna element 131 to stop supplying power to the at least one antenna element 131, thereby causing the at least one antenna element 131 to stop working. Alternatively, the first controller 140 controlling the at least one antenna element 131 to stop working may also be that the first controller 140 controls the at least one antenna element 131 to be turned off, thereby causing the at least one antenna element 131 to stop working.

[0028] Therefore, when the user wears the head mounted electronic device 100, the temples 120 of the head mounted electronic device 100 can be unfolded, so that the first controller 140 can control at least one antenna array element 131 to be in a working state. Further, when the user finishes using the head mounted electronic device 100, the head mounted electronic device 100 can be removed and the temples can be folded, and at this time, the first controller 140 can control at least one antenna array element 131 to stop working.

[0029] The head-mounted electronic device provided by the above-mentioned embodiment of the present application can, when the user is not using the head-mounted electronic device 100 and folds the temples 120, the first controller 140 controls at least part of the antenna array elements in the head-mounted electronic device 100 to stop working, thereby reducing the power consumption of the head-mounted electronic device 100, saving electrical energy of the head-mounted electronic device 100, and extending the working time of the head-mounted electronic device 100.

[0030] Optionally, in order to enable the temple 120 to be unfolded or folded relative to the frame 110, the temple 120 can be connected to the frame 110 by means of a hinge, etc. Of course, other ways of keeping the temple 120 and the frame 110 rotatably connected are not excluded.

[0031] It should be noted that Figure 1 The antenna array elements in Figure 1 The arrangement position and the arrangement quantity (indicated as black triangles in FIG. 1 ) are only examples. The antenna array elements in the antenna array 130 may be arranged only on the temple 120, or only on the frame 110, or may be arranged on both the temple 120 and the frame 110. As an example, Figure 1 The antenna array 130 may include 12 antenna elements. In actual applications, the number of antenna elements may be less than 12 or more than 12. In short, the number of antenna elements and the positions of the antenna elements in the antenna array 130 may be selected according to actual needs.

[0032] It should be understood that, under normal circumstances, when the temple 120 is in the unfolded state, the head-mounted electronic device 100 may be worn and used by the user, in which case the first controller 140 may control the at least one antenna array element 131 to work to provide a larger communication bandwidth; when the temple 120 is in the folded state, it means that the user is not using the head-mounted electronic device 100, such as when the user places the head-mounted electronic device 100 somewhere, in which case the communication bandwidth that may be required is smaller, and the first controller 140 may control the at least one antenna array element 131 to stop working. Those skilled in the art can determine the specific number of the at least one antenna array element 131 controlled by the first controller 140 according to actual needs, and there is no specific limitation here.

[0033] In the above embodiment of controlling the at least one antenna array element 131 to work or stop working as a whole according to the state of the temple 120, the above first controller 140 may be implemented in a variety of ways.

[0034] Optionally, to facilitate the implementation of the embodiment of the present application, the first controller 140 may include a simple structure, such as a circuit structure, so as to directly send a simple signal for controlling at least one antenna array element 131 according to the state of the temple 120.

[0035] As an example, Figure 2 As shown, it is a structural schematic diagram of the first controller of the head-mounted electronic device provided according to an embodiment of the present application. The first controller 140 may include: a high-low level switching circuit 141, which is electrically connected to the at least one antenna array element 131 and can be used to output a high level when the temple 120 is in the unfolded state and a low level when the temple 120 is in the folded state. Among them, the high level output by the high-low level switching circuit 141 can be used to control the operation of the connected antenna array element. That is, the high level signal output by the high-low level switching circuit 141 can turn on the antenna array element electrically connected thereto so that it can receive power feeding. The low level output by the high-low level switching circuit 141 can be used to control the connected antenna array element to stop working. That is, the low level signal output by the high-low level switching circuit 141 can turn off the antenna array element electrically connected thereto so that it can not receive power feeding. Here, Figure 2 The high-low level switching circuit 141 can be electrically connected to each antenna array element 1311 - 1313 in the at least one antenna array element 131 to output a level corresponding to the state of the temple 120 to the at least one antenna array element 131 .

[0036] As an example, Figure 3 As shown, it shows Figure 2 Here, the high-low level switching circuit 141 may include: an NPN transistor Q, such as Figure 3 The collector of the NPN transistor Q is electrically connected to the power source VCC of the head mounted electronic device 100 through the first resistor R1, the emitter of the NPN transistor Q is grounded through the second resistor R2, the base of the NPN transistor Q is grounded through the third resistor R3, and is electrically connected to the fourth resistor R4 and the power source VCC through the key S.

[0037] The at least one antenna array element 131 can be connected to the high-low level switching circuit 141 through the high-low level output point. The button S can be replaced by other components such as a hardware switch, which can be used to control the high-low level switching circuit 141 to be turned on or off. The resistors R1 to R4 can limit the current in the circuit and play a role in protecting the circuit.

[0038] like Figure 3 As shown, it should be noted that the power supply VCC in the high-low level switching circuit 141 can be a power supply for feeding the antenna array 130 or a power supply for feeding the at least one antenna array element 131, or it can be an additional power supply, and the embodiment of the present application does not limit this.

[0039] like Figure 3 As shown, when the temple 120 is in the folded state, the button S is disconnected (for example, the button S can be set at the connection between the temple 120 and the frame, so that the button S is controlled to be deformed to turn off when the temple 120 is folded), and the high-low level switching circuit 141 is disconnected. At this time, the connection point 1 is at a low level, the high-low level output point is at a high level, the NPN type transistor Q is cut off, and the at least one antenna array element 131 is turned off, and the current cannot be obtained, so it stops working. When the temple 120 is in the unfolded state, the button S is closed, and the high-low level switching circuit 141 is turned on. At this time, the connection point 1 is at a high level, the high-low level output point is at a low level, the NPN type transistor Q is turned on, and the at least one antenna array element 131 is turned on, and the current can be obtained, so it is in a working state.

[0040] certainly, Figure 3 The NPN transistor Q in the high-low level switching circuit 141 can be adjusted to a PNP transistor, and the connection method between other components in the high-low level switching circuit 141 and the PNP transistor is also adjusted accordingly, which can also realize the function of the high-low level switching circuit 141 in the head-mounted electronic device 100 provided in the embodiment of the present application.

[0041] In conclusion, Figure 3 The high-low level switching circuit 141 shown can directly convert the state of the temple 120 into a high-low level signal that can control whether at least one antenna array element 131 stops working. Figure 3 The circuit diagram in the figure is only an example, and different circuits can actually be used to implement the above functions.

[0042] In another optional implementation, the first controller 140 may include: a mechanical switch 142. The mechanical switch 142 may be connected between a power source and the at least one antenna array element 131. The power source may supply power to the at least one antenna array element 131, and the mechanical switch 142 may be turned off when the temple 120 is in a folded state, so that the at least one antenna array element 131 stops working. The mechanical switch 142 may be turned on when the temple 120 is in an unfolded state, so that the at least one antenna array element 131 works. This implementation simplifies the structure of the first controller 140, reduces the occupied space of the first controller 140, thereby reducing the cost of the head-mounted electronic device and reducing the volume of the head-mounted electronic device.

[0043] Below Figures 4 to 7As an example, the arrangement position and working principle of the mechanical switch 142 in the head mounted electronic device 100 provided in the embodiment of the present application are described in detail. The temple 120 here can be either the first temple 121 or the second temple 122, and the frame 110 is similar.

[0044] Figure 4 A schematic diagram of a position of a mechanical switch in a head-mounted electronic device when the temples are in an unfolded state according to an embodiment of the present application. Figure 4 In the embodiment, the mechanical switch 142 can be fixedly arranged on the frame 110, the temple 120 and the frame branch 111 can be connected through the connecting element 410, and the mechanical switch 142 can be a mechanical button. Therefore, when the temple 120 is unfolded, the mechanical switch 142 can be pressed, so that the mechanical switch 142 is turned on. The frame branch 111 can be a bracket extending outward from the frame 110 to connect the temple 120 and the frame 110.

[0045] The connecting element 410 may be an element connecting the frame branch 111 and the temple 120, such as a hinge. When the user folds the temple 120 in the unfolded state, or unfolds the temple 120 in the folded state, one end of the temple 120 connected to the frame 110 may rotate around one end of the frame branch 410 through the connecting element 410.

[0046] Furthermore, combined with Figure 5 right Figure 4 The following describes area A in FIG. Figure 5 for Figure 4 The schematic diagram of the partial structure of the head-mounted electronic device shown in FIG. Figure 5 As shown, when the temple 120 is in the unfolded state, one end of the temple 120 close to the frame 110 squeezes the mechanical switch 142, so that the exposed key length of the mechanical switch 142 is shortened to x, thereby turning on the mechanical switch 142.

[0047] Figure 6 A schematic diagram of a position of a mechanical switch in a folded state of the temples of a head-mounted electronic device provided according to an embodiment of the present application. Figure 4 Similarly, in Figure 6 In the embodiment, the mechanical switch 142 can be fixedly arranged on the frame 110, the temple 120 is connected to the frame branch 111 via the connecting element 410, and the mechanical switch 142 can be a mechanical button. Therefore, when the temple 120 is folded, it can be separated from the contact with the mechanical switch 142, so that the mechanical switch 142 is turned off.

[0048] Furthermore, combined with Figure 7 right Figure 6 The following describes area B in FIG. Figure 7 for Figure 6The schematic diagram of the partial structure of the head-mounted electronic device shown in FIG. Figure 7 As shown, when the temple 120 is in the folded state, the end of the temple 120 close to the frame 110 is not in contact with the mechanical switch 142, so that the key of the mechanical switch 142 pops up, and the exposed key length is the same as the complete key length y, so that the mechanical switch 142 is turned off. The length y of the mechanical key popping up is usually greater than the length x of the mechanical key being squeezed.

[0049] Optionally, the mechanical switch 142 can also be a common circuit switch. The closing of the mechanical switch 142 can enable the circuits at both ends to be connected through the mechanical switch 142, and the resistance value of the mechanical switch 142 can be ignored. At this time, the mechanical switch 142 can be equivalent to a wire in the circuit. Therefore, when the mechanical switch 142 is closed, the mechanical switch 142 connects the at least one antenna array element 131 with the power supply in the head-mounted electronic device 100 for feeding power to the at least one antenna array element 131, so that the power supply of the head-mounted electronic device 100 can supply power to the at least one antenna array element 131, so that the at least one antenna array element 131 can start working. When the mechanical switch 142 is disconnected, the mechanical switch 142 can disconnect the connection between the at least one antenna array element 131 and the power supply of the head-mounted electronic device 100, so that the power supply of the head-mounted electronic device 100 stops supplying power to the at least one antenna array element 131, and the at least one antenna array element 131 can stop working.

[0050] Of course, it should be understood that the above Figure 3 The button S in the high-low level switching circuit 141 shown can also be implemented by a mechanical switch 142 to cut off or turn on the high-low level switching circuit 141 according to the state of the temple 120.

[0051] It should be noted that Figures 4 to 7 The selection and setting position of the mechanical switch 142, as well as the connection method and relative position of the temple 120 and the frame 110, are only examples to facilitate understanding of the technical solution of the present application, and the embodiments of the present application do not limit their specific implementation.

[0052] Alternatively, if Figure 4 and Figure 6 In the example, in order to be able to timely obtain changes in the state of the temple 120, in the head-mounted electronic device 100 provided in the embodiment of the present application, the mechanical switch 142 can be set at the connection between the frame 110 and the temple 120.

[0053] Optionally, the mechanical switch 142 may also be disposed on an end of the temple 120 away from the connection with the frame 110 , or disposed at a position on the frame 110 that can contact or approach the temple 120 when folded.

[0054] Of course, in addition to the method of directly controlling the antenna array element by the high-low level switching circuit 141 or the mechanical switch 142, the embodiment of the present application can also control the antenna array element by the processor 143. It can be understood that there are also multiple implementations for the first controller including the processor 143.

[0055] It should be understood that there are various ways to obtain the state of the temple 120. In addition to structures such as the mechanical switch 142, the state of the temple 120 can also be obtained through various sensors. Figure 8 FIG. 2 is another structural diagram of a first controller in a head mounted electronic device according to an embodiment of the present application. Figure 8 As shown, the first controller 140 may include a temple state collector 144 and a processor 143. The temple state collector 144 may collect state indication information. The state indication information may be used to indicate the state of the temple 120. The processor 143 may include a signal input terminal and a signal output terminal. The signal input terminal may receive the state indication information, and the signal output terminal may be electrically connected to the at least one antenna array element 131. The processor 143 may determine the state of the temple 120 according to the state indication information, and control the at least one antenna array element 131 to work when the temple 120 is in the unfolded state, and control the at least one antenna array element 131 to stop working when the temple 120 is in the folded state.

[0056] In this way, the temple state collector 144 can be set at different positions of the head-mounted electronic device 100 according to the needs of collecting state indication information, rather than being limited to fixed positions such as the connection between the frame 110 and the temple 120, so that the development and design personnel can more flexibly arrange the internal and external structures of the head-mounted electronic device 100. The processor 143 can determine the state of the temple 120 according to the state indication information collected by the temple state collector 144, and directly turn on or off the antenna array element connected to the temple 120 according to the determined state of the temple 120.

[0057] Here, after receiving the status information of the temple 120, the processor 143 may generate a corresponding enable signal according to the status information of the temple 120, and send the enable signal to the antenna array element electrically connected to the processor 143. The enable signal may directly control the opening and closing of the antenna array element electrically connected thereto, so that the processor 143 may control whether the antenna array element works according to the status indication information.

[0058] Optionally, in addition to the processor 143 directly controlling the operation or stopping of the at least one antenna array element 131, the processor 143 may also control whether the feeding circuit feeds the at least one antenna array element 131 to control whether the at least one antenna array element is operating. The feeding circuit may be a circuit structure capable of providing electrical energy to the at least one antenna array element 131, for example, a circuit including a power supply.

[0059] For example, Fig. 9 FIG. 2 is another structural diagram of a first controller in a head mounted electronic device according to an embodiment of the present application. Fig. 9 As shown, the first controller 140 may include a temple state collector 144, a feeding circuit 145 and a processor 143. The temple state collector 144 may collect state indication information. The state indication information is used to indicate the state of the temple 120. The feeding circuit 145 may include a feeding control terminal and a feeding output terminal. The feeding output terminal is electrically connected to at least one antenna array element 131. The signal input terminal of the processor 143 may receive the state indication information collected by the temple state collector 144, and the signal output terminal of the processor 143 may be electrically connected to the feeding control terminal of the feeding circuit. The processor 143 may include a signal input terminal and a signal output terminal. The signal input terminal may be used to receive the state indication information, and the signal output terminal may be electrically connected to the feeding control terminal. The processor 143 can determine the state of the temple 120 according to the state indication information, and control the feeding output end to feed the at least one antenna array element 131 through the feeding control end when the temple 120 is in the unfolded state, and control the feeding output end to stop feeding the at least one antenna array element 131 through the feeding control end when the temple 120 is in the folded state.

[0060] In this way, the temple state collector 144 disposed at any position of the head mounted electronic device 100 can send the collected state indication information to the processor. Then, the processor 143 can determine the state of the temple 120 according to the correspondence between the state indication information and the state of the temple 120. The processor 143 can send a control signal to the feeding circuit 145 according to the state of the temple 120, so that the feeding circuit 145 stops or starts supplying power to at least one antenna array element 131, thereby controlling whether the at least one antenna array element 131 is working.

[0061] The state indication information of the temple 120 may include the relative position relationship between the temple 120 and the frame 110. Then, the distance between the end of the temple 120 away from the connection and the frame 110 may be determined according to the relative position relationship between the temple 120 and the frame 110, and the distance may represent the state of the temple 120. Here, the connection may be the distance between the temple 120 and the frame 110.

[0062] For example, in order to intuitively determine the state of the temple 120 according to the distance between the temple 120 and the frame 110, the temple state collector 144 may include a distance sensor 1441. The distance sensor 1441 is arranged on the temple 120, and the distance sensor 1441 can collect the distance information between the distance sensor 1441 and the frame 110, wherein the distance information can be used to indicate the state of the temple 120. It should be understood that when the distance sensor 1441 is arranged on the temple 120, the lens or light emitting port of the distance sensor 1441 can be aligned with the frame 110 to accurately obtain the distance information between the distance sensor 1441 and the frame 110.

[0063] It should be understood that Fig.10 , which is another structural diagram of the first controller in the head-mounted electronic device provided according to an embodiment of the present application. The output end of the above-mentioned ranging sensor 1441 can be connected to the signal input end of the processor 143, and the signal input end of the processor 143 can be connected to at least one antenna array element 131.

[0064] like Fig.11 As shown, it is another structural schematic diagram of the first controller in the head-mounted electronic device provided according to an embodiment of the present application. Of course, the output end of the ranging sensor 1441 can be connected to the signal input end of the processor 143, the signal input end of the processor 143 is connected to the feeding control end of the feeding circuit 145, and the feeding output end of the feeding circuit 145 is connected to at least one antenna array element 131.

[0065] Among them, the position of the ranging sensor 1441 on the temple 120 can be an end of the temple 120 away from the connection between it and the frame 110, or it can be a position on the temple 120 at a preset length away from the connection between it and the frame 110, and the embodiment of the present application is not limited to this.

[0066] Optionally, the distance sensor 1441 may also be arranged on the frame 110, and the distance sensor 1441 may collect distance information between the distance sensor 1441 and the temple 120, wherein the distance information between the distance sensor 1441 and the temple 120 may also be used to indicate the state of the temple 120. It should be understood that when the distance sensor 1441 is arranged on the frame 110, the lens or light emitting port of the distance sensor 1441 may be aligned with the temple 120 to accurately obtain the distance information between the distance sensor 1441 and the temple 120.

[0067] The distance measuring sensor 1441 may be arranged on the frame 110 at the center of the frame 110 or at a position on the frame 110 that is a preset length away from the center of the frame 110 , and this embodiment of the present application does not limit this.

[0068] For another example, the distance sensor 1441 included in the temple status collector 144 can also be used to collect distance information between the distance sensor 1441 and the temple 120 when the distance sensor 1441 is set on the frame 110, wherein the distance information is used to indicate the status of the temple 120.

[0069] Among them, the status indication information of the above-mentioned temple 120 may include the relative position relationship between the temple 120 and the frame 110. Then, based on the relative position relationship between the temple 120 and the frame 110, the distance between the frame 110 and the end of the temple 120 away from the connection with the frame 110 can be determined, thereby determining whether the temple 120 is in a folded state or in an unfolded state.

[0070] To facilitate understanding of the process in which the processor 143 controls the at least one antenna array element 131 according to the status indication information of the temple 120, the following example is used for explanation. If the processor 143 determines that the distance between the temple 120 and the frame 110 acquired by the ranging sensor 1441 is greater than or equal to the first preset distance, it can be indicated that the temple 120 is in an unfolded state. The processor 143 can control the at least one antenna array element 131 to work, or control the feeding circuit 145 to feed power to the at least one antenna array element 131. If the processor 143 determines that the distance between the temple 120 and the frame 110 acquired by the ranging sensor 1441 is less than or equal to the second preset distance, it can be indicated that the temple 120 is in a folded state. At this time, the processor 143 can control the at least one antenna array element 131 to stop working, or control the feeding circuit 145 to stop feeding power to the at least one antenna array element 131. Among them, the first preset distance is usually greater than the second preset distance.

[0071] Fig.12 FIG. 1 is another structural diagram of a first controller in a head-mounted electronic device according to an embodiment of the present application. Fig.12 As shown, when the state of the temple 120 is determined according to the distance between the temple 120 and the mirror frame 110, the temple state collector 144 may further include a high-low level switching circuit 1442. The high-low level switching circuit 1442 may output different level signals when the temple is in different states. Wherein, the level signal may be used to indicate the state of the temple 120, and the level signal may include a high level and a low level. For example, it may be determined that the temple 120 is in an extended state according to the high level signal sent by the high-low level switching circuit 1442, and it may be determined that the temple 120 is in a folded state according to the low level signal sent by the high-low level switching circuit 1442.

[0072] In this way, developers can design the circuit structure, setting position, and correspondence between the level signal and the state of the temple 120 of the high and low level switching circuit 1442 according to actual needs, so that the processor 143 can determine the state of the temple 120 according to the level signal emitted by the high and low level switching circuit 1442 and the above correspondence, thereby controlling whether the at least one antenna array element 131 is working.

[0073] For example, when the output end of the high-low level switching circuit 1442 can be connected to the signal input end of the processor 143, and the signal output end of the processor 143 is connected to the at least one antenna array element 131, the high-low level switching circuit 1442 can output high and low level signals for indicating the status of the temple 120 to the processor 143, so that the processor can send an enable signal to the antenna array element connected thereto according to the high and low level signals to control whether the antenna array element connected thereto is working.

[0074] For example, Fig.13 As shown, it is another structural schematic diagram of the first controller in the head-mounted electronic device provided according to an embodiment of the present application. When the output end of the high-low level switching circuit 1442 is connected to the signal input end of the processor 143, the signal output end of the processor 143 is electrically connected to the feeding control end of the feeding circuit, and the feeding output end of the feeding circuit is connected to the at least one antenna array element 131, the high-low level switching circuit 1442 can output a high-low level signal for indicating the state of the temple 120 to the processor 143, so that the processor sends a control signal to the feeding circuit according to the high-low level signal to control whether the feeding circuit provides power to the antenna array element connected thereto.

[0075] For ease of understanding, as an example, the internal structure of the high-low level switching circuit 1442 in the temple state collector 144 can be as follows: Figure 3 The high-low level switching circuit 141 in the first controller is shown. In this example, the high level output by the high-low level switching circuit 1442 can be used to indicate the unfolded state of the temple 120, and the low level output by the high-low level switching circuit 1442 can be used to indicate the folded state of the temple 120.

[0076] Understandably, Fig.13 The high-low level switching circuit in can also be implemented in other ways. For example, Figure 3 The high-low level switching circuit shown in the figure adds an inverter as Fig.13At this time, the high level output by the high-low level switching circuit 1442 can be used to indicate the folded state of the temple 120, and the processor 143 can control the at least one antenna array element 131 to stop working, or control the feeding circuit 145 to stop feeding power to the at least one antenna array element 131. The low level output by the high-low level switching circuit 1442 can be used to indicate the unfolded state of the temple 120, and the processor 143 can control the at least one antenna array element 131 to work, or control the feeding circuit 145 to feed power to the at least one antenna array element 131.

[0077] Fig.14 This is a schematic diagram of the connection relationship between the device parameter collector and the first controller in the head-mounted electronic device provided in the embodiment of the present application. Fig.14 As shown, the head-mounted electronic device 100 may further include a device parameter collector 146. The device parameter collector 146 may be used to collect parameters related to the operating state of the head-mounted electronic device 100. The collected parameters may characterize the environmental state of the head-mounted electronic device and the operating state of the head-mounted electronic device itself. The signal input end of the processor 143 may also be electrically connected to the output end of the device parameter collector 146. The processor 143 may be used to determine the operating state of the at least one antenna array element 131 according to the state of the temple 120, and adjust the operating state of the antenna array elements in the antenna array 130 according to the parameters related to the operation of the head-mounted electronic device 100.

[0078] It is understandable that those skilled in the art can determine the antenna array elements that the processor 143 adjusts according to the parameters related to the operation of the head-mounted electronic device 100 according to the needs of the world, and the determined antenna array elements may include the at least one antenna array element 131 or may not include the at least one antenna array element 131, and the embodiments of the present application are not limited to this. Accordingly, the processor 143 can adjust all antenna array elements in the antenna array 130 or some antenna array elements in the antenna array 130 according to the parameters related to the operation of the head-mounted electronic device 100.

[0079] It should be understood that in the embodiment of the present application, there are many parameters related to the operating state of the head-mounted electronic device 100. For example, it may include at least one of the WIFI connection state parameter of the head-mounted electronic device 100, the ambient light information of the head-mounted electronic device 100, the flow information of the head-mounted electronic device 100, and the remaining power of the head-mounted electronic device 100. Of course, it is not excluded that there are other operating state related parameters that affect the control of the antenna array element, which are not specifically limited here.

[0080] Accordingly, the above-mentioned equipment parameter collector 146 may include one or more collection devices. Fig.15Schematic diagram of a device parameter collector in a head-mounted electronic device according to an embodiment of the present application. In order to determine the working state of each antenna array element by integrating the operating state of the head-mounted electronic device 100 as much as possible, as shown in FIG. Fig.15 As shown, the device parameter collector 146 and the collected parameters related to the operating status of the head-mounted electronic device 100 may include at least one of the following: a WIFI connection parameter collector 1461, which can collect the WIFI connection status parameters of the head-mounted electronic device 100; an ambient light information collector 1462, which can collect the ambient light information of the head-mounted electronic device 100; a power parameter collector 1463, which can collect the remaining power information of the head-mounted electronic device 100.

[0081] It should be understood that the power parameter collector 1463 collects the remaining power information of the power supply that supplies power to the head-mounted electronic device 100, not the power supply that feeds the at least one antenna array element 131.

[0082] More specifically, the WIFI connection status information of the head-mounted electronic device 100 may include whether the head-mounted electronic device 100 is connected to WIFI, the ambient light information of the head-mounted electronic device 100 may include the brightness of the light in the environment where the head-mounted electronic device 100 is located, the remaining power information of the head-mounted electronic device 100 may include the percentage of power remaining in the head-mounted electronic device 100, and so on.

[0083] The following is an example of the first controller 140 controlling the antenna array element of the at least one antenna array element 131. As an example, if the temple 120 is determined to be in a folded state according to the data collected by the temple state collector 144, and the head-mounted electronic device 100 is determined to be connected to WIFI according to the data collected by the WIFI connection state collector 1461 in the device parameter collector 146, the processor 143 can determine that the user is not wearing the head-mounted electronic device 100. At this time, the data transmission requirements of the head-mounted electronic device 100 are relatively low, and there is no need to use data transmission capabilities with strong directivity and / or high transmission rate, and the basic data communication of the head-mounted electronic device 100 when it is in standby mode can be maintained through WIFI. Then, the processor 143 can control the at least one antenna array element 131 (including all high-frequency antenna array elements in the antenna array 130) to stop working.

[0084] As another example, if the temple 120 is determined to be in a folded state according to the data collected by the temple state collector 144, and the head-mounted electronic device 100 is determined to be not connected to WIFI according to the data collected by the WIFI connection state collector 1461 in the device parameter collector 146, the processor 143 can determine that the user is not wearing the head-mounted electronic device 100. At this time, the data transmission requirements of the head-mounted electronic device 100 are relatively low, and there is no need to use data transmission capabilities with strong directivity and / or high transmission rates, but a small number of antenna elements are required to work to maintain basic data communication when the head-mounted electronic device 100 is on standby. Then, the processor 143 can control the at least one antenna element 131 (including a small number of antenna elements in the antenna array 130) to work, and the remaining antenna elements in the antenna array 130 stop working.

[0085] As another example, if the temple 120 is determined to be in the unfolded state according to the data collected by the temple state collector 144, and the head-mounted electronic device 100 is determined to be not connected to WIFI according to the data collected by the WIFI connection state collector 1461 in the device parameter collector 146, the processor 143 can determine that the user is wearing the head-mounted electronic device 100. At this time, the head-mounted electronic device 100 requires higher data transmission requirements, and needs to use data transmission capabilities with stronger directivity and / or higher transmission rate, and there is no WIFI to provide data communication for the head-mounted electronic device 100. Then, the processor 143 can control to keep the at least one antenna array element 131 (including all high-frequency antenna array elements in the antenna array 130) working.

[0086] As another example, if the temple 120 is determined to be in the unfolded state according to the data collected by the temple state collector 144, and the head-mounted electronic device 100 is determined to be connected to WIFI according to the data collected by the WIFI connection state collector 1461 in the device parameter collector 146, the processor 143 can determine that the user is wearing the head-mounted electronic device 100. At this time, the data transmission requirements required by the head-mounted electronic device 100 are relatively high, and a data transmission capability with strong directivity and / or high transmission rate is required, but a part of the data communication can be provided for the head-mounted electronic device 100 through WIFI. Then, the processor 143 can control the at least one antenna array element 131 (including some antenna array elements in the antenna array 130) to stop working.

[0087] Optionally, as an embodiment, the at least one antenna array element 131 is composed of all antenna array elements of the antenna array 130. That is, the first controller 140 can control all antenna array elements in the antenna array 130, so that the first controller 140 can uniformly control whether all antenna array elements in the head-mounted electronic device 100 are working, thereby controlling the opening or closing of the data transmission function of the head-mounted electronic device 100.

[0088] Alternatively, optionally, as another embodiment, the multiple antenna elements of the antenna array 130, in addition to the at least one antenna element 131, also include other antenna elements. Generally, the other antenna elements can remain in a normally open state. In other words, the first controller 140 can only control some of the antenna elements in the antenna array 130, thereby controlling some of the antenna elements in the head-mounted electronic device 100 to stop working, thereby reducing the power consumption of the head-mounted electronic device 100.

[0089] Furthermore, when the at least one antenna array element 131 does not include all antenna array elements in the antenna array 130, in order to be able to uniformly control the working status of all antenna array elements in the antenna array 130 through one controller, the head-mounted electronic device 100 may also include a second controller. The second controller may control the feeding status of all antenna array elements in the antenna array 130 according to the status of the temple 120, or may not control the feeding status of the antenna array 130 according to the status of the temple 120. Assume that the head-mounted electronic device 100 now has m antenna array elements turned on and n antenna array elements turned off. At this time, the second controller may control to stop feeding the m+n antenna array elements, or restore the feeding status of the m+n antenna array elements to: feeding the m+n antenna array elements.

[0090] It should be understood that in the examples of the present application, there are many ways to implement the second controller. For example, the second controller can also directly control whether the antenna array elements in the antenna array 130 stop working. Of course, there may be other implementation methods, which are not limited by the embodiments of the present application. In addition, the embodiments of the present application do not limit the location of the second controller.

[0091] It should be understood that the head-mounted electronic device 100 generally has two temples, a first temple and a second temple, and also has two frames, a first frame and a second frame (the two frames here refer to frames corresponding to each eye of the wearer respectively). Accordingly, when the antenna array element is controlled, the working state or feeding state of the antenna array elements of the two parts can be controlled separately. Among them, the antenna array elements of the two parts refer to the antenna array elements of the first part and the antenna array elements of the second part. The antenna array elements of the first part may include at least one antenna array element 131 arranged on the first temple and the first frame, and the antenna array elements of the second part may include at least one antenna array element 131 arranged on the second temple and the second frame.

[0092] For example, the first controller 140 in the head mounted electronic device 100 provided in the embodiment of the present application may include a first controller and a second controller. The first controller may be used to control the antenna array element of the at least one antenna array element 131 disposed on the first temple 121 and the first frame 111. The second controller may be used to control the antenna array element of the at least one antenna array element 131 disposed on the second temple 122 and the second frame 112.

[0093] As an example, when one side of the head mounted electronic device 100 is close to the interactive device, the temple close to the interactive device can be unfolded, and the temple away from the interactive device can be folded, so as to control whether the antenna array elements of the two parts work. For example, when the first frame and the first temple are close to the interactive device, and the second frame and the second temple are away from the interactive device, the first temple can be unfolded and the second temple can be folded, so that the first controller controls the antenna array elements of the first part to work, and the second controller controls the antenna array elements of the second part to stop working.

[0094] It should be understood that when controlling the antenna array elements, the working state or feeding state of the two parts of the antenna array elements can also be controlled according to the state of one temple, so that the user can control it with one hand.

[0095] For example, the first controller 140 in the head-mounted electronic device 100 provided in the embodiment of the present application may also include one of the first controller or the second controller, so that the at least one antenna array element 131 (including the antenna array element arranged on the first temple 121 and the first frame 111 and the antenna array element arranged on the second temple 122 and the second frame 112) can be controlled to work according to the state of one of the first temple 121 or the second temple 122.

[0096] As an example, when the user wears or takes off the head mounted electronic device 100 with one hand, the user can control whether all antenna elements in the at least one antenna array element 131 are working by unfolding or folding one temple. It should be understood that the controller for controlling the at least one antenna array element 131 can be selected according to the user's left or right hand usage habits.

[0097] Optionally, in the head-mounted electronic device 100 provided in an embodiment of the present application, at least part of the antenna array elements of the at least one antenna array element 131 may be arranged on the upper edge and the lower edge of the frame 110, wherein the upper edge and the lower edge of the frame 110 refer to the edges of the mirror located on both sides of the horizontal midline of the frame 110, and when the user wears the head-mounted electronic device 100, the edge of the mirror close to the user's eyebrows is the upper edge, and the other edge of the mirror is the lower edge.

[0098] For example, Fig.16 As shown, it is a schematic diagram of an antenna array element in a head-mounted electronic device according to an embodiment of the present application. Fig.16 In the figure, the antenna array element is represented by a black triangle, and the direction of the arrow indicates the direction of the antenna array element and the signal transmission direction. In order to prevent the signal transmission direction of the highly directional 5G signal from being limited by the setting direction of the antenna array element, the antenna array element can be set at various positions of the head-mounted electronic device 100, such as the upper and lower edges of the frame 110 and the temples 120. Among them, the signal transmission direction of the antenna array element set on the upper edge of the frame 110 is upward, the signal transmission direction of the antenna array element set on the lower edge of the frame 110 is downward, and the signal transmission direction of the antenna array element set on the temples 120 is toward the outside of the head-mounted electronic device 100.

[0099] Optionally, in order to enable the head mounted electronic device 100 to still transmit data with the interactive device when the user wears the head mounted electronic device 100 with his back to the interactive device, in the head mounted electronic device 100 provided in the embodiment of the present application, at least part of the at least one antenna array element 131 may be arranged at one end of the temple 120 away from the connection with the frame 110, wherein the end of the temple 120 away from the connection with the frame 110 is usually located at the part for hooking the user's ear. Fig.16 As shown in , the antenna array elements 1314 and 1315 can be arranged at one end of the temple 120 away from the connection with the frame 110. In this way, when the user wears the head-mounted electronic device 100, the antenna array elements 1314 and 1315 allow the temple part located at the back of the user's head to also receive signals, thereby expanding the signal coverage range and improving the communication effect of the head-mounted electronic device.

[0100] Furthermore, if the array elements on the temples and frames are set as follows Fig.14As shown, the head-mounted electronic device 100 can provide signals in all directions around the user's head. The antenna array elements arranged on the upper and lower sides of the frame 110 can also provide signals on the upper and lower sides of the head-mounted electronic device 100. Finally, when the user wears the head-mounted electronic device 100, the parts of the head-mounted electronic device 100 located at all directions of the user's head can receive or send signals.

[0101] Optionally, in order to improve the data transmission efficiency of the head-mounted electronic device 100, the antenna array 130 in the head-mounted electronic device 100 provided in the embodiment of the present application may be a 5G antenna array. Then, the above-mentioned design of arranging the antenna array elements 1314 and 1315 at one end of the temple 120 away from the connection with the frame 110 can avoid the 5G signal from being unable to transmit because the antenna array elements are not facing the interactive device. Of course, the antenna array 130 may also be an antenna array other than 5G.

[0102] Optionally, in the head-mounted electronic device 100 provided in the embodiment of the present application, all working antenna array elements in the antenna array 130 may have the ability to jointly provide the head-mounted electronic device 100 with network residency and communicate in a preset communication mode.

[0103] Optionally, the head-mounted electronic device 100 may also include a WIFI module, and all the working antenna elements in the antenna array 130 and the WIFI module in the head-mounted electronic device 100 have the ability to provide the head-mounted electronic device 100 with network residency and communication in a preset communication mode. Among them, the preset communication mode, for example, may include a normal communication mode and a low-speed communication mode, and so on. Among them, the normal communication mode often requires more communication bandwidth, and the low-speed communication mode requires less communication bandwidth. The sleep mode can be understood as a low-speed communication mode. For example, the normal communication mode can be the working mode of the head-mounted electronic device 100 when the temple 120 is unfolded, including a mode in which all antenna elements in the antenna array 130 are required to work. The low-speed communication mode can be the working mode of the head-mounted electronic device 100 when the temple 120 is folded, including a mode in which some antenna elements in the antenna array 130 are required to work.

[0104] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of further restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

[0105] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
