[0002] Currently, in order to improve antenna signals, the antennas of more and more mobile terminals such as mobile phones are distributed around the body; at the same time, in order to pursue a higher screen-to-body ratio, the control buttons of mobile terminals are also distributed on the side or top of the body.

[0003] However, the above configuration method causes certain mutual influence between the antenna and the button in both design and actual use. For example, the signal routing of the button itself will affect the antenna performance, and the user's contact and pressing of the button will also affect the antenna performance.

[0004] In addition, as the number of antennas in mobile terminals such as mobile phones increases, it is possible that antennas will be designed inside the touch screen of the touch display in the future. In this case, the antenna conductor will generally cover the touch layer of the screen, causing the antenna area to be unable to realize the touch function. Summary of the invention

[0029] 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.

[0030] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0031] The control method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0032] See also Figure 1 , shows a step flow chart of a control method provided in an embodiment of the present application, wherein the method may include steps 100~400.

[0033] In an embodiment of the present application, the method is applied to an electronic device, which includes an antenna. The electronic device can be a mobile electronic device such as a mobile phone, a tablet computer, a laptop computer, a PDA, a vehicle-mounted electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a personal digital assistant (PDA), or a non-mobile electronic device such as a personal computer (PC), a television (TV), a teller machine or a self-service machine, as long as the electronic device is provided with an antenna.

[0034] The antenna may be an exterior antenna or a built-in antenna; the built-in antenna includes but is not limited to an antenna built into the body of the electronic device, or an antenna built into a screen or other component. The wearable device may be a smart watch, smart glasses, etc. The antenna of a smart watch may be arranged on the front of the dial or on the side wall of the dial for easy touch operation by the user; the antenna of smart glasses may be arranged on the lens or on the temple for easy touch by the user.

[0035] Step 100: Detect the ratio of the reflected voltage of the antenna to the input voltage.

[0036] In the above step 100, the electronic device in the embodiment of the present application has a closed-loop tuning system, and can use a closed-loop tuning (Closed Loop Tuner) technology to detect the offset of the antenna impedance. The offset of the above antenna impedance is specifically described by the ratio of the reflected voltage of the antenna to the input voltage. Therefore, it is necessary to continuously detect the reflected voltage and input voltage of the above antenna, and calculate the ratio of the above reflected voltage to the input voltage to obtain the above ratio.

[0037] Step 200 : When the ratio deviates from a preset ratio range, generate a touch signal or a tuning signal according to the duration for which the ratio continuously deviates from the threshold range.

[0038] In the above step 200, the above preset ratio range is a range corresponding to the threshold value that needs to be regulated according to the antenna impedance offset; when the ratio of the above reflected voltage to the input voltage is within the above preset ratio range, it is determined to be a normal antenna impedance fluctuation, and thus no touch signal or tuning signal is generated, which can prevent the user from accidentally touching the area where the antenna is located, causing the ratio of the antenna's reflected voltage to the input voltage to change, thereby causing the electronic device to perform unnecessary control actions;

[0039] When the ratio of the above-mentioned reflected voltage to the input voltage deviates from the above-mentioned preset ratio range, that is, when the above-mentioned ratio exceeds or is not within the above-mentioned preset ratio range, the antenna impedance fluctuates greatly, and the impedance matching state of the antenna needs to be adjusted to reduce the interference to the antenna efficiency, thereby generating a tuning signal to trigger the electronic device to optimize the impedance matching state of the antenna; when the ratio of the above-mentioned reflected voltage to the input voltage deviates from the above-mentioned preset ratio range, it may also be caused by the user's intentional touch operation on the antenna area, thereby generating a touch signal to trigger the electronic device to perform a corresponding touch response operation, thereby realizing the user's usage needs.

[0040] Therefore, when the above-mentioned ratio deviates from the above-mentioned preset ratio range, it is possible to distinguish whether the antenna impedance deviation is caused by a touch operation with touch indication intentionally performed by the user, or by a continuous touch operation on the antenna area without touch indication performed by the user, based on the duration of the ratio deviation from the above-mentioned threshold ratio range, and then generate a touch signal or a tuning signal accordingly.

[0041] In actual applications, since human skin and muscle tissue are materials with very high dielectric constants, when making or receiving calls or using a mobile terminal, as long as human limbs such as hands are close to or in contact with the antenna, it will cause antenna impedance shift and electromagnetic wave absorption. This phenomenon will affect the antenna efficiency within the antenna's operating frequency band, thereby reducing the wireless communication performance of the electronic device.

[0042] Step 300: When the touch signal is detected, a corresponding touch response operation is performed in response to the touch signal.

[0043] In the above step 300, because when a touch signal is detected, it means that the duration of the antenna impedance offset caused by the user's current touch operation on the antenna falls within the duration range corresponding to the touch response. Therefore, the electronic device responds to the above touch signal and executes the touch response operation corresponding to the touch signal, thereby realizing the function corresponding to the user's touch operation.

[0044] In the above step 300, the antenna area is equivalent to being used as a touch button or a physical button, that is, it is equivalent to adding and setting a touch response function in a closed-loop tuning system. By detecting the change in the ratio of the reflected voltage to the input voltage caused by the user's touch operation on the antenna area, the specific touch operation performed by the user is determined, and then a corresponding touch signal is generated, and then the corresponding touch response operation is performed.

[0045] Step 400: When the tuning signal is detected, adjust the impedance matching state of the antenna in response to the tuning signal.

[0046] In the above step 400, because the tuning signal is detected, it means that the duration of the antenna impedance deviation caused by the user's current touch operation on the antenna falls within the duration range corresponding to the tuning response. Therefore, the electronic device responds to the above tuning signal and adjusts the impedance matching state of the antenna to reduce the impact of impedance mismatch on the antenna efficiency within the working frequency band, so as to avoid reducing the performance of wireless communication of the electronic device.

[0047] In actual applications, the impedance offset of the antenna generated when the human body approaches or touches the antenna is detected by using a closed loop tuning (Closed Loop Tuner) technology, and the antenna impedance is adjusted back to a normal state by switching to a matching circuit preset in the closed loop tuning system through a switch, that is, adjusting the above ratio to return to the above threshold ratio range.

[0048] The control method provided by the embodiment of the present application detects the ratio between the reflected voltage and the input voltage of the antenna; when the ratio deviates from the preset ratio range, a touch signal or a tuning signal is generated according to the duration of the ratio continuously deviating from the threshold range; when a touch signal is detected, a corresponding touch response operation is performed in response to the touch signal; when a touch tuning signal is detected, the impedance matching state of the antenna is adjusted in response to the tuning signal. In the above control process, by detecting the change in the ratio of the reflected voltage to the input voltage when the antenna is touched, the response range of the system is determined by the duration of the change, and then a corresponding touch signal or a tuning signal is generated, and a corresponding touch response operation is performed when the touch signal is generated, and the different signal interferences caused by different touch operations to the antenna can be used to realize the corresponding touch input; and when generating the tuning signal, according to the above ratio, the impedance matching state of the antenna is adjusted accordingly, which can improve the impedance matching state of the antenna and enhance the antenna signal. Therefore, the above control method solves the problem of mutual interference between the antenna function and the button function caused by the overlap of the setting position of the antenna and the setting position of the control button in the prior art.

[0049] Optionally, in one implementation, in the control method provided by an embodiment of the present invention, the above step 200 includes steps 201-202.

[0050] Step 201 : When the ratio deviates from a preset ratio range and the duration for which the ratio continuously deviates from the threshold range is less than or equal to a preset duration threshold, generate a touch signal according to the duration.

[0051] In the above-mentioned step 201, the above-mentioned preset duration threshold is a duration threshold for defining a duration range corresponding to a touch response and a duration range corresponding to a tuning response, that is, the duration is divided into two duration ranges, namely, a duration range corresponding to a touch response and a duration range corresponding to a tuning response, using the above-mentioned threshold duration threshold; wherein, because the longer the duration of the antenna impedance offset caused by the user's touch operation on the antenna lasts, the greater the impact on the antenna efficiency and the wireless communication performance of the electronic device, and therefore, the duration range in which the duration of the antenna impedance offset is less than or equal to the above-mentioned preset duration threshold can be set as the duration range corresponding to the touch response, and the duration range greater than the above-mentioned preset duration threshold can be set as the duration range corresponding to the tuning response.

[0052] Therefore, when the duration for which the above-mentioned ratio deviates from the above-mentioned preset ratio range is less than or equal to the above-mentioned preset time threshold, it means that the duration for which the antenna impedance deviation caused by the user's current touch operation on the antenna lasts belongs to the duration range corresponding to the touch response, that is, the current antenna impedance deviation is caused by the user's intentional performance of a touch operation with a touch indication. Therefore, according to the specific duration for which the above-mentioned ratio deviates from the preset ratio range, a corresponding touch signal is generated to respond to the user's touch operation.

[0053] Step 202: When the ratio deviates from the preset ratio range, and the duration for which the ratio continuously deviates from the threshold range is greater than the preset duration threshold, generate a tuning signal according to the ratio.

[0054] In the above step 202, when the duration for which the above ratio deviates from the above preset ratio range is equal to the above preset time threshold, it means that the duration for which the antenna impedance deviation caused by the user's current touch operation on the antenna lasts belongs to the time range corresponding to the tuning response, that is, the current antenna impedance deviation is not caused by the user's intentional touch operation with touch indication. Therefore, according to the specific duration for which the above ratio deviates from the preset ratio range, a corresponding tuning signal is generated to adjust the impedance matching state of the antenna, reduce the influence of impedance mismatch on the antenna efficiency within the working frequency band, and avoid reducing the performance of wireless communication of the electronic device.

[0055] In the above embodiment, when the ratio of the reflected voltage of the antenna to the input voltage deviates from the preset ratio range, if the duration for which the above ratio deviates from the preset ratio range is less than or equal to the preset duration threshold, a touch signal is generated, otherwise a tuning signal is generated. This can more reasonably utilize the different signal interferences to the antenna caused by different touch operations to achieve corresponding touch inputs, and improve the impedance matching state of the antenna to a greater extent, enhance the antenna signal, and effectively reduce the problem of mutual interference between the antenna function and the button function caused by the overlap of the setting position of the antenna and the setting position of the control button.

[0056] Optionally, in a specific implementation, in the control method provided by an embodiment of the present invention, the electronic device pre-establishes a correspondence between the time range for which the ratio of the reflected voltage to the input voltage deviates from the preset ratio range and the touch signal; the above-mentioned step 201 includes steps 2011~2012.

[0057] In this specific implementation, the time range for which the ratio of the reflected voltage to the input voltage of the antenna required for different touch signals deviates from the preset ratio range is set in advance according to the actual conditions of the antenna and the electronic device, thereby determining the above correspondence.

[0058] Step 2011: determine the target duration range within which the duration falls.

[0059] In the above-mentioned step 2011, because the time ranges during which the above-mentioned ratio deviates from the preset ratio range are different to trigger different touch signals, when it is detected that the ratio of the reflected voltage to the input voltage deviates from the preset ratio range, it is necessary to first determine which time range of the time ranges corresponding to each touch signal the duration belongs to, so as to determine the above-mentioned target time range.

[0060] Step 2012: Determine the touch signal according to the target duration range and the corresponding relationship.

[0061] In the above step 2012, because the above correspondence relationship presets the time range for which the ratio of the reflected voltage to the input voltage of the above antenna required for different touch signals deviates from the preset ratio range, when it is determined that the ratio of the reflected voltage to the input voltage of the antenna caused by the user's current touch operation on the antenna area deviates from the preset ratio range, and the duration corresponds to the above target duration range, according to the above correspondence relationship, the touch signal corresponding to the above target duration range can be determined, that is, the control signal expressed by the user's current touch operation on the antenna area.

[0062] In the above implementation, the time range for which the ratio of the reflected voltage to the input voltage of the above antenna required for different touch signals deviates from the preset ratio range is set in advance according to the actual conditions of the antenna and the electronic device. This can improve the fault tolerance rate for users to trigger the required touch signal by touching the antenna area, thereby bringing convenience to users.

[0063] Optionally, in one implementation, the antenna includes multiple antenna areas; the step 201 includes steps 2013 and 2014.

[0064] In this implementation, the antenna surface is divided into a plurality of antenna areas in advance according to the specific structure of the antenna, and when each antenna area is touched by a user, the ratio between the corresponding reflected voltage and the input voltage is different.

[0065] Step 2013: Determine a first touch antenna area according to the ratio.

[0066] In the above step 2013, since each antenna area presents a different ratio between the reflected voltage and the input voltage when touched by the user, the antenna area touched by the user can be distinguished by detecting the degree of change in the ratio between the reflected voltage and the output voltage of the antenna.

[0067] Optionally, a correspondence between a ratio range and an antenna area can be established in advance based on the specific structure of the antenna, where the above ratio is the ratio between the reflected voltage and the input voltage; after calculating the actual ratio between the reflected voltage and the input voltage of the antenna, the ratio range in which the actual ratio lies is determined, thereby determining the antenna area touched by the user.

[0068] The above method can improve the error tolerance of judging the specific antenna area touched by the user through the actual ratio between the reflected voltage and the input voltage of the antenna, avoid the identification error of the antenna area caused by slight fluctuation of the ratio, and provide convenience for the user to touch the antenna area to trigger the corresponding control signal.

[0069] Step 2014: Determine a touch signal corresponding to the first antenna area according to the duration.

[0070] In the above step 2014, after the first antenna area currently touched by the user is determined through step 2013, on the premise that the duration for which the above ratio deviates from the above preset ratio range is less than or equal to the preset duration threshold, the specific touch operation performed by the user on the first antenna area can be determined based on the duration for which the above ratio deviates from the above preset ratio range, thereby generating a touch signal for the first antenna area.

[0071] In the above embodiment, the antenna surface is divided into multiple antenna areas, and the degree of change in the ratio of the reflected voltage to the output voltage of the antenna is detected to distinguish and judge the antenna area specifically triggered by the user, and the specific touch signal for the antenna area is determined in combination with the duration of the change, thereby increasing the touch function achieved through the antenna.

[0072] Optionally, in a specific implementation, in the control method provided by an embodiment of the present invention, the above step 202 includes steps 2021 and 2022.

[0073] Step 2021: Determine a second touch antenna area according to the ratio.

[0074] The above step 2021 can refer to the detailed description of step 2013, which will not be repeated here.

[0075] Step 2022: Determine a tuning signal corresponding to the second antenna area according to the duration.

[0076] In the above step 2022, after the second antenna area currently touched by the user is determined through step 2021, on the premise that the duration for which the above ratio deviates from the above preset ratio range is greater than the preset duration threshold, the touch operation performed by the user on the second antenna area can be determined, thereby generating a tuning signal for the second antenna area.

[0077] In the above embodiment, by dividing the antenna surface into multiple antenna areas, by detecting the degree of change in the ratio of the reflected voltage to the output voltage of the antenna, the antenna area specifically triggered by the user is distinguished and judged, and the specific touch signal or tuning signal for the antenna area is determined in combination with the duration of the change. This can increase the touch function achieved by the antenna and increase the antenna input impedance improvement function.

[0078] See also Figure 2 and Figure 3 , Figure 2 A schematic diagram of the system architecture of the electronic device 21 in the embodiment of the present application is shown. Figure 3 A schematic diagram showing the connection relationship between the various components of the electronic device 21 in the embodiment of the present application is shown.

[0079] like Figure 2 and 3 As shown, the electronic device includes a storage and processing circuit system 210, and an input-output circuit system 220;

[0080] The storage and processing circuit system 210 includes at least a touch input module 211 and a tuning control module 212; the input-output circuit system 220 includes an input-output device 221 and a wireless communication circuit system 222, and the wireless communication circuit system 222 includes a local connection transceiver 223, a cellular network connection transceiver 224, an antenna input-reflection voltage detection circuit 225, a tuning circuit 226 and an antenna 227. The local connection transceiver 223 includes a WiFi module and a Bluetooth module.

[0081] The local connection transceiver 223 and the cellular network connection transceiver 224 are respectively connected to the antenna input-reflection voltage detection circuit 225 through lines 11 and 12, and then respectively connected to the tuning circuit 226 through line 13, connected to the touch input module 211 through line 15, and connected to the tuning control module 212 through line 16; the tuning circuit 226 is respectively connected to the antenna 227 through line 14 and connected to the tuning control module 212 through line 17.

[0082] It should be noted that the local connection transceiver 223 and the cellular network connection transceiver 224 are not necessarily connected to the antenna input-reflection voltage detection circuit 225 at the same time, which needs to be determined according to the actual function of the antenna 227. For example, if the antenna is the antenna corresponding to the cellular network connection transceiver 224, the cellular network connection transceiver 224 needs to be connected to the antenna input-reflection voltage detection circuit 225.

[0083] See also Figure 4 , shows a control logic schematic diagram of an electronic device in an embodiment of the present application.

[0084] like Figure 4 As shown, in step 401, the antenna input-reflection voltage detection circuit 225 detects whether the reflection / input voltage ratio of the antenna deviates from the preset ratio range. If so, step 402 is performed today, otherwise, the detection is restarted;

[0085] In step 402, when a human body touches the antenna area and causes the reflection / input voltage ratio of the antenna to change and exceed a preset ratio range, the response range of the reflection / input voltage ratio of the antenna is determined by the duration of the change;

[0086] In step 403, if the duration of the change is less than the preset duration threshold, it is determined as a touch response range; if the duration is longer than the preset duration threshold, it is determined as a tuning response range;

[0087] The duration of the change is divided into n touch corresponding sub-ranges 1, 2, …, n in advance, and touch signals St1, St2, …, Stn are generated respectively. Then, after the touch sub-range in which the duration of the change is located is determined, the corresponding touch signal is sent to the touch input module 211; the touch input module 211 implements the corresponding touch input function according to the received touch signals St1, St2, …, Stn respectively;

[0088] Among them, the time longer than the above-mentioned preset time threshold is judged as the tuning response range, and a tuning signal Si is generated and sent to the tuning control module 212; and the tuning control module 212 controls the tuning circuit 226 to adjust the circuit working mode according to the received tuning signal Si to optimize the impedance matching state of the antenna 227.

[0089] See also Figure 5 , shows another control logic schematic diagram of the electronic device in an embodiment of the present application.

[0090] like Figure 5 As shown, the surface of the antenna 227 is first divided into n regions A1, A2, ..., An, etc. according to the formation of the antenna. The shape and region division method of the antenna 227 can be referred to in Figure 6 ;

[0091] In step 501, the antenna input-reflection voltage detection circuit 225 detects whether the reflection / input voltage ratio of the antenna deviates from the preset ratio range. If yes, the process proceeds to step 502. Otherwise, the detection is restarted.

[0092] In step 502, when a human body touches the antenna area and causes the antenna reflection / input voltage ratio to change and exceed a preset ratio range, the area touched by the human body is determined by distinguishing the value of the antenna reflection / input voltage ratio after the change;

[0093] In step 503, the response range of the antenna reflection / input voltage ratio is determined by the duration of the change;

[0094] In step 504, if the duration of the change is less than the preset duration threshold, it is determined as a touch response range, and if the duration is longer than the preset duration threshold, it is determined as a tuning response range;

[0095] The touch response range is divided into response sub-ranges (1,1), (1,2), …, (m,n) according to the sub-range where the antenna reflection / input voltage ratio changes for a certain period of time and the touch area, and touch signals (St1,A1), (St1,A2), …, (Stm,An) are generated respectively; the tuning response range is divided into sub-ranges 1, 2, …, n according to the touch area, and tuning signals (A1), (A2), …, (An) are generated respectively;

[0096] Then, according to the range of the duration of the change in the antenna reflection / input voltage ratio and the determined area touched by the human body, a specific touch signal or tuning signal for the area is generated, and the corresponding touch signal is sent to the touch input module 211, and the corresponding tuning signal is sent to the tuning control module 212;

[0097] Among them, the touch input module 211 implements the corresponding touch input function according to the received touch signals St1, St2, …, Stn respectively; and the tuning control module 212 controls the tuning circuit 226 to adjust the circuit working mode according to the received tuning signals (A1), (A2), …, (An) to optimize the impedance matching state of the antenna 227.
