[0057] To make the objectives, features, and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0058] To make the objectives, technical solutions, and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings. The described embodiments should not be regarded as limitations to the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0059] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments. However, it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0060] In the following description, the terms "first / second" involved are only used to distinguish similar objects and do not represent a specific order for the objects. Understandably, "first / second" can be interchanged with a specific order or sequence when allowed, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0062] It should be understood that in various embodiments of the present application, the magnitude of the serial numbers of each implementation process does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of this application.

[0063] The electronic device involved in this application can be a mobile phone, a laptop computer, a tablet computer, a wearable device, etc. Preferably, the electronic device is a laptop computer or a tablet computer.

[0064] In this application, a solution for positioning the position of a target object through two components of an electronic device and determining a working parameter for adjusting the transmission power of an antenna based on the position of the target object and the position of the target antenna can avoid the adverse effects caused by the electromagnetic radiation of the antenna on the target object. Using two existing components of the electronic device to reduce the transmit / receive power of the antenna eliminates the need to set up new detection components, avoiding unnecessary occupation of the space of the electronic device due to the setting up of new detection components. Based on this, an adaptive antenna working parameter adjustment strategy is determined, and different strategies can adapt to different usage scenarios.

[0065] Figure 1 Shows the implementation process schematic of the control method in the embodiments of this application Figure 1 。The control method is applied to an electronic device, such as Figure 1 shown, and the method includes:

[0066] S101: Obtain a first signal, which is collected by a first component.

[0067] S102: Analyze the first signal. If the first signal meets the first condition, determine the first position of the target object based on the first signal and the second signal; the second signal is output by a second component, the first component is different from the second component, and the first condition indicates that the first signal is a reflected signal of the second signal.

[0068] In this application, the electronic device includes two components: a first component and a second component. Among them, the first component is a component for collecting signals, such as a microphone (MIC). The second component is a component for outputting signals, such as a speaker or a horn (Speaker). The second signal emitted by the speaker can be an ultrasonic signal and can be used to locate the (first) position of the target object. For convenience of description, the second signal can be regarded as a signal for locating the human body position, and the first signal can be regarded as a reflected signal for locating the human body position.

[0069] It can be understood that when the speaker emits an ultrasonic signal, if a target object such as a person or a part of a person (hand, leg) approaches the electronic device, the propagation of the ultrasonic signal will be blocked by the target object, and a reflected signal will be generated.

[0070] In S101, the microphone collects the signals in the environment where the electronic device is located, and takes the signals collected by the microphone as the first signal. In S102, the signals collected by the microphone are analyzed. If it is analyzed that the signals collected by the microphone are the reflected signals of the ultrasonic signals emitted by the speaker, it is considered that the first signal meets the first condition.

[0071] Because the reflected signal of the ultrasonic wave is generated due to the presence of an obstacle in the propagation path of the ultrasonic wave, if the signal collected by the microphone is the reflected signal of the ultrasonic signal emitted by the speaker, it means that a target object such as a human hand approaches the electronic device. Based on the ultrasonic signal emitted by the speaker and the signal collected by the microphone, the position where the human hand appears is located to avoid the harm caused by the electromagnetic radiation of the antenna to the human body when the human body approaches the antenna.

[0072] In addition to outputting ultrasonic signals, the speaker can also output the audio required for the operation of different applications of the electronic device, such as the voice of a chat software, the music of a multimedia software, etc. It can be understood that in this embodiment, the output form of the audio signal is related to the type of the microphone. If the speaker is an ultrasonic speaker, then the audio signal is output by the ultrasonic load. If the speaker supports both the output of ultrasonic signals and the output of traditional sound signals, then the audio signal is a traditional sound signal. The audio signal is a signal that can be heard by the human ear, and its frequency is different from that of the ultrasonic signal. The frequency of the ultrasonic signal is usually higher than that of the audio signal, and the frequency of the reflected signal of the ultrasonic signal is slightly lower than the frequency of the ultrasonic signal itself (it should be noted that due to the Doppler effect, the frequency of the reflected ultrasonic wave may also be slightly higher).

[0073] When parsing the first signal, it is possible to parse whether the frequency of the signal collected by the microphone is the same as or close to the frequency of the reflected signal of the ultrasonic signal emitted by the speaker. If so, it is considered that the first condition is met. Since the ultrasonic signal will generate a reflected signal due to the occlusion of the target object, the intensity of the reflected signal is usually less than that of the ultrasonic signal. In the air, there is a corresponding relationship between the propagation intensity of the ultrasonic signal and the propagation distance. For example, when the propagation distance is A kilometers, the propagation intensity drops to B dm. Thus, according to this corresponding relationship and the difference between the intensity of the ultrasonic signal emitted by the speaker and the intensity of the signal collected by the microphone, it is possible to estimate at what propagation distance the ultrasonic signal emitted by the speaker is reflected. Given the position of the speaker and this propagation distance, it is easy to know at what position the ultrasonic signal is reflected, and this position is the position where the human hand is located.

[0074] S103: Determine a target policy based on the first position and the second positions of at least one target antenna, where the target policy is used to adjust the operating parameters of the at least one target antenna.

[0075] In this application, the electronic device includes one or more antennas. The position of each antenna in the (second) position where the electronic device is located is easy to know. The target antenna refers to the antenna in the working state. The states of the antennas in the electronic device include a working state in which signal transmission can be performed, and a sleep or off state in which signal transmission is not required. Usually, the state of the antennas in the electronic device is determined by the processor of the electronic device, such as the CPU (Central Processing Unit). Thus, the state of the antenna can be obtained from the CPU. Considering that the antenna transmits the signal of the electronic device with a certain transmit / receive power, therefore, the operating parameter of the target antenna can be the transmit / receive power (transmission power) of the antenna.

[0076] It can be understood that the closer the human body is to the antenna, the more harm it will cause. If the position where the human hand appears in the electronic device is far from the position of the (working) antenna, a non-target policy that does not adjust the transmit power of the antenna can be determined. If the position where the human hand appears is close to the position of the antenna, a target policy that adjusts the transmission power of the antenna can be determined. Usually, the higher the transmission power, the stronger the electromagnetic radiation to the human body. To reduce the radiation to the human body, the target policy can be a policy of reducing the transmission power of the antenna. The above is an explanation of the scenario of the solution in the case of the position of the human hand and the position of a single antenna.

[0077] In addition, the number of antennas in the working state may also be two or more. If the position where the human hand appears is close to the positions of two or more (working) antennas, then a target strategy for reducing the transmission power of each antenna can be determined. Among them, the reduction amplitude of the transmission power of each antenna may be the same or different, depending on the specific situation. If the position where the human hand appears is close to the position of one of the two or more (working) antennas and far from the positions of other antennas, then a target strategy for reducing the transmission power of that one antenna can be determined, and a non-target strategy for not reducing the transmission power of other antennas.

[0078] In S101 to S103, there is no need to set up new detection components. The existing components of the electronic device are used to implement the positioning of the target object. Based on the position of the target object and the position of the target antenna, the operating parameter of adjusting the transmission power of the antenna is determined, which can avoid the adverse effects caused by the electromagnetic radiation of the antenna on the target object. Based on the position of the target object and the position of the target antenna, an adaptive antenna operating parameter adjustment strategy is determined. Different strategies can adapt to different usage scenarios to meet different usage requirements. It avoids the unnecessary occupation of the space of the electronic device caused by setting up new detection components.

[0079] In this application, the execution subject of S101 to S103 may be the EC (embedded processor) of the electronic device. The EC obtains the first signal by reading or receiving the signal collected by the microphone of the electronic device. In addition, it is also possible that the execution subject of S101 is the microphone of the electronic device, and the execution subjects of S102 to S103 are the EC of the electronic device.

[0080] In this application, the solution shown in S101 to S103 can be used when the electronic device is in the power-on state and uses at least one antenna for signal transmission.

[0081] It can be understood that the frequency range of traditional audio signals is usually 20 - 20000 Hz (Hertz), which is the sound that the human ear can hear. The frequency of ultrasonic signals is greater than 20000 Hz. From the perspective of frequency, traditional audio signals and ultrasonic signals are two different types of signals. For the normal output of these two types of signals by the same speaker, in this application, the second component can be set to include two channels: the first channel and the second channel. The second component can output the second signal through the first channel, and the second component can output the third signal carrying audio through the second channel; where the vibration frequency of the second signal is higher than that of the third signal. Or, the second component outputs the third signal carrying audio through the first channel, and the second component outputs the second signal through the second channel. If there is no special instruction, the first situation is the main one.

[0082] Generally speaking, the loudspeaker in this application can output two different signals through two different channels. Among them, the first channel can be used to output ultrasonic signals. The second channel can output traditional audio signals or ultrasonic signals. In some scenarios, since this application realizes the positioning of the human body based on the ultrasonic signal output by the loudspeaker and the reflected signal of the ultrasonic signal, the loudspeaker can output the ultrasonic signal for human body positioning through the first channel, and the microphone can obtain the reflected signal for human body positioning by collecting the reflected signal of the ultrasonic signal output by the loudspeaker through the first channel.

[0083] For the case where the loudspeaker has two channels, at the same or similar time, the same loudspeaker can output the second signal through the first channel and also output the third signal carrying audio through the second channel to simultaneously realize the positioning of the human body and the normal output of the audio signal. It is also possible that at the same or similar time, the same loudspeaker can only output the signal corresponding to one of the channels to realize the positioning of the human body or the normal output of the audio signal.

[0084] For the case where the loudspeaker has two channels, in some embodiments, in response to the second component outputting the third signal carrying audio through the second channel, the third signal is used as the second signal output by the second component. In response to the second component not outputting the third signal carrying audio through the second channel, the second component outputs the second signal through the first channel. Among them, the third signal can be an audio signal or can include an audio signal and any other reasonable sound signals, such as noise, ultrasonic waves, etc. In the foregoing solution, when the electronic device needs the loudspeaker to output an audio signal, the loudspeaker can output the third signal through the second channel to realize the normal output of the audio signal of the electronic device by outputting the third signal. In this case, the third signal output by the loudspeaker through the second channel can be used as the (second) signal for positioning the human body. When the electronic device does not need the loudspeaker to output an audio signal, the loudspeaker can output the second signal for human body positioning through the first channel. In this way, in different situations, the normal output of the (second) signal for positioning the human body is realized by using two channels, so as to realize the normal positioning of the human body in different situations.

[0085] In this application, it is possible to set the second component to include a single channel. This single channel is used to output two different signals. In some embodiments, if the electronic device meets the audio output condition, the second component outputs a third signal carrying audio through the first channel, and uses the third signal as the second signal output by the second component. If the electronic device does not meet the audio output condition, the second component outputs the second signal through the first channel. Among them, the need for audio output by the electronic device can be regarded as meeting the audio output condition, and the lack of need for audio output by the electronic device can be regarded as not meeting the audio output condition. From the two situations of the electronic device needing to output audio and not needing to output audio, if it is the situation where the electronic device needs to output audio, the speaker can output a third signal carrying audio through this single channel, and use the third signal output by the speaker through this channel as the (second) signal for positioning the human body. If it is the situation where the electronic device does not need to output audio, the speaker can output the second signal for positioning the human body through this single channel. In this way, in different situations, the normal output of the (second) signal for positioning the human body is achieved by using a single channel, so as to achieve the normal positioning of the human body in different situations.

[0086] In this application, for the first component - the microphone, if the environment where the electronic device is located is a relatively quiet environment, such as when the audio-video software of the electronic device does not run or the video software plays audio-video in a mute mode, etc., in the scenario where the application of the electronic device does not require audio output (no audio, no echo of audio), and the external environment where the electronic device is located is relatively quiet (no noise, no speaking sound), the (first) signal collected by the microphone is the reflected signal of the ultrasonic signal output by the speaker. Analyze the first signal, and it is parsed that the first signal is a signal that meets the first condition. If the environment where the electronic device is located is not a relatively quiet environment, such as in the scenario where the audio-video software of the electronic device plays audio-video and the electronic device has audio output (there is audio, there is an echo of audio), and the external environment where the electronic device is located is relatively noisy (there is noise, speaking sound), the (first) signal collected by the microphone includes not only the reflected signal of the ultrasonic signal output by the speaker, but also various types of sounds shown above. That is, the (first) signal collected by the microphone also includes a fourth signal that meets the second condition, and the fourth signal includes at least one type of audio. Among them, the audio signal that meets the frequency of the sound signal, the frequency of the echo, the noise frequency, and the speaking sound frequency can be regarded as a signal that meets the second condition. The fourth signal can be at least one of types of sounds such as the echo of the audio sound, noise, speaking sound, etc.

[0087] Considering that the reflection signal of the ultrasonic signal has a different frequency from each type of sound shown above, the signal that meets the first condition can be parsed from the first signal collected by the microphone through frequency identification of the sound signal, that is, the reflection signal of the ultrasonic signal output by the speaker, so as to realize the positioning of the target object based on the ultrasonic signal output by the speaker and the parsed reflection signal of the ultrasonic signal. For the fourth signal shown above, it can be processed as needed to avoid the adverse effects brought by these sounds. For example, for the noise in the above fourth signal, the noise can be processed according to the noise reduction scheme to remove the noise or reduce it to a certain level so as not to affect the clear output of the audio by the speaker and the impact on position positioning.

[0088] In this application, for the first component - the microphone, it has a first state and a second state. Among them, the first state indicates that the first component is closed, and the second state indicates that the first component is turned on. The collection of the first signal by the microphone is usually the collection of the reflection signal when the microphone is in the on state. In addition, in this application, for the microphone in the off state, a method is provided to enable the microphone in the off state to collect the reflection signal normally. The method is: the first component in the first state can collect the first signal that meets the first condition and cannot collect the signal that meets the second condition. Or, the first component in the first state can collect all the first signals, but cannot output based on the first signal that meets the second condition.

[0089] Generally speaking, when the speaker outputs an audio signal and an ultrasonic signal for positioning at the same time and the microphone is off, the virtual microphone designed based on the (physical) microphone can be used to collect the reflection signal. If the echo, noise, and speech of the audio sound are regarded as interference sounds for the ultrasonic signal used for human positioning, then the virtual microphone can distinguish the reflection signal of the ultrasonic wave and the interference sound based on the frequency of the reflection signal of the ultrasonic wave and the frequency of these interference sounds, and only collect the reflection signal of the ultrasonic wave without collecting the interference sound. Or, the virtual microphone collects all the signals (reflection signal and interference sound), but does not output the interference sound. For example, it does not output the voice of the speaker to the opposite end, and only uses the reflection signal to execute the process of positioning the human body position. In this way, even when the microphone is physically muted, it is also possible to collect the reflection signal of the ultrasonic signal output by the speaker and realize the normal positioning of the human body, and the normal reduction of the antenna transmission power to avoid the impact of antenna radiation on the human body.

[0090] It can be understood that when users use electronic devices for meetings, considering the quietness of the meetings, the microphones of the participants are usually turned off, and only the microphone of the host is retained. There is a need to reduce the radiation of the electronic devices to the human body for both the electronic devices of the participants and the host. For the electronic devices of the participants, even when their microphones are physically muted, through the foregoing solution, it is still possible to reduce the transmission power of the antenna and reduce the harm caused to the human body when the electronic devices are in normal use.

[0091] In the electronic device of the present application, the number of microphones and speakers can be one, two or more. To ensure the accuracy of human body positioning, two or more microphones and two or more speakers can be provided in the electronic device. In the electronic device as Figure 2 shown, it includes two microphones (MIC 1 and MIC 2) and four speakers (SPK 1 - SPK4).

[0092] In the present application, taking the electronic device as a laptop computer, the antenna in the laptop computer is located in the main body where the keyboard is located, and the main body where the keyboard is located and the main body where the screen is located can be linked through a linkage mechanism as an example, and taking the lower left corner of the main body where the keyboard is located as the coordinate origin, a coordinate system is established, as Figure 2 and Figure 3 shown.

[0093] The positions of each microphone and each speaker in the coordinate system are easily known. Based on each speaker, each microphone, and the ultrasonic signals emitted by each speaker, and the reflected signals of the ultrasonic signals collected by each microphone, the (first) position of the target object can be calculated.

[0094] Specifically, as shown in Figure 3 , each of the four speakers emits its own ultrasonic signal and records the time when each speaker emits the ultrasonic signal. Each microphone collects the reflected signals of the ultrasonic signals emitted by each speaker and records the time when each collected reflected signal is received. For the emission time of an ultrasonic signal and the collection time of the reflected signal of this ultrasonic signal, the propagation time of this ultrasonic signal in the air can be obtained. Ultrasonic waves have a transmission speed in the air, and the propagation distance of this ultrasonic signal in the air is the product of the propagation speed of the ultrasonic signal in space and the transmission time of this ultrasonic signal in the air. Four speakers emit ultrasonic signals, and each of the two microphones collects the reflected signals of the ultrasonic signals emitted by these four speakers. There are 8 propagation paths from the emission to the collection of the ultrasonic waves, and 8 propagation distances d 1 ~d 8 can be obtained. Through these 8 propagation distances, the positions of the four speakers, and the positions of the two microphones, the following equations can be constructed.

[0095]

[0096] Among them, is the coordinate of MIC 1 in the coordinate system; is the coordinate of MIC 2 in the coordinate system. (x 1 , y 1 , z 1 ) is the coordinate of SPK 1 in the coordinate system; (x 2 , y 2 , z 2 ) is the coordinate of SPK 2 in the coordinate system; (x 3 , y 3 , z 3 ) is the coordinate of SPK 3 in the coordinate system; (x 4 , y 4 , z 4 ) is the coordinate of SPK 4 in the coordinate system at the position. Solving the above system of equations can obtain the position (x, y, z) of the target object.

[0097] As described above, the number of antennas in the present application can be one, can be two or more, preferably two or more. As Figure 4 shown in the electronic device, it includes four antennas such as Ant1, Ant 2, Ant 3, and Ant 4.

[0098] In the present application, the foregoing S103: The solution for determining the target strategy based on the first position and the second positions of at least one target antenna can be implemented through S1031 to S1032. As Figure 5 shown, the method includes:

[0099] S1031: Obtain the reference position range of the target antenna based on the second position of the target antenna and the safety position value of the target antenna.

[0100] In the present application, the second position refers to the actual position of the target antenna in the electronic device. The actual position of each antenna in the electronic device is easily known. Naturally, when the microphone collects the reflected signal for human body position positioning, the actual position of the antenna in the working state is easily known. Considering the harm of the radiation generated by the antenna to the human body, in this step, a safety position value is configured for the target antenna. This safety position value can be understood as: the radiation harm received outside this safety position value is much smaller than the radiation harm received inside this safety position. This safety position value can be a critical value to maximize the protection of the human body from radiation harm. In this step, it can be regarded as the construction scheme of the reference position range of the target antenna.

[0101] S1032: If the first position is within the reference position range, determine the target policy; if the first position is outside the reference position range and the motion state of the target object is moving from the first position to within the reference position range, determine the target policy.

[0102] It can be understood that relative to the actual position of the target antenna, the reference position range of the target antenna can be a position range that covers the actual position of the target antenna. For example, with the actual position of the target antenna as the center, a certain position area is expanded outward, and this position area can be regarded as the reference position range of the target antenna. In this way, once it is determined that the human body position is within the reference position range, the radiation damage can be reduced by reducing the transmission power of the antenna. It can effectively avoid the problem of radiation damage to the human body caused by the lack of timeliness in reducing the antenna transmission power when the human body approaches the actual position of the target antenna. If it is determined that the human body position is outside the reference position range, but the human body moves from the current position towards the reference position range of the target antenna, the harm caused by the antenna radiation to the human body can also be reduced by reducing the transmission power of the antenna.

[0103] Among them, when the human body is at the first position and the first position is outside the reference position range, the motion image of the human body can be collected by an image acquisition device such as a camera of the electronic device, and the motion direction of the human body can be estimated from the collected image, so as to realize the judgment of whether it moves from the first position to within the reference position range. In addition, the speaker can emit ultrasonic signals at different times, and the microphone can collect the reflected signals of the ultrasonic signals emitted by the speaker at different times. Based on the ultrasonic signal emitted by the speaker in the previous time and the reflected signal collected by the microphone for the ultrasonic signal in the previous time, the previous position of the human body is calculated. Based on the ultrasonic signal emitted by the speaker in the subsequent time and the reflected signal collected by the microphone for the ultrasonic signal in the subsequent time, the subsequent position of the human body is calculated. Through the analysis of the previous position and the subsequent position, the judgment of whether the human body moves from the first position to within the reference position range can also be realized.

[0104] In S1031 - S1032, based on the judgment of the human body's position and the constructed reference position range, the determination of whether to reduce the power of the antenna is realized, which can protect the human body to the greatest extent and reduce the harm of antenna radiation to the human body.

[0105] In this application, the target antenna can be of the first shape. The second position of the target antenna includes the coordinate information of multiple first boundaries of the target antenna in the first shape. Thus, the construction scheme of the reference position range of the target antenna can be as Figure 6 shown.

[0106] S601: Obtain multiple second boundary information based on the coordinate information of multiple first boundaries of the target antenna and the safety position values of the target antenna under the multiple first boundaries.

[0107] Take the first shape as a cuboid or a cube as an example. As Figure 4 shown, the shape of the antenna is a cuboid. The cuboid includes six faces, and the six faces can be regarded as the (first) boundaries of the cuboid. Taking Ant 3 among the four antennas as an example, it includes six faces: the front face, the back face, the left side face, the right side face, the upper face, and the lower face. Under the established coordinate system, the point coordinates on each face can be easily obtained.

[0108] Considering that in practical applications, the human hand approaches the antenna gradually by approaching the edge of the notebook body and then approaching the inside along the edge of the body, and due to the particularity of the actual position of each antenna, some of the six faces can be taken as the first boundaries for constructing the reference position range. For example, Ant 3 is located in the lower right corner of the body where the keyboard is located. Its right side face (right Sideedge), lower face (bottom), upper face (top), and front face (Front edge) are close to the edge of the body, and these four faces can be used to construct the reference position range of Ant 3.

[0109] In this application, under the requirements or constraints of SAR laws and regulations, measure the safety position values of the four faces of the selected Ant 3. As Figure 7 shown in the right figure, from the perspective of the Top view of the antenna, the safety position value a' under the right Side edge and the safety position value b' under the Front edge can be measured. From the side view perspective of the antenna, the safety position value c' under the top and the safety position value d' under the bottom can be measured. a', b', c', and d' can be the safety values of the corresponding faces among the four faces of Ant 3. The radiation damage to the human body by the antenna outside this value is much less than that inside this value. Add the coordinate points on each of the four faces of Ant 3 to the corresponding safety values on each face, and use the four obtained results as the four second boundary information.

[0110] S602: Construct a target object based on the multiple second boundary information and the shape of the target antenna; where the target object is of the second shape and can wrap the target antenna of the first shape;

[0111] In this step, four results are obtained by adding the coordinate points on each of the four faces of Ant 3 to the corresponding safety values on the same faces. These four results represent four new faces (the new upper face, the new lower face, the new right face, and the new front face). Based on these four new faces, a new cuboid is constructed. The constructed new cuboid is the target object, and constructing the new cuboid can enclose Ant 3 in the shape of a cuboid.

[0112] In this application, the constructed target object can be any shape that can enclose the antenna, such as a cuboid, a cube, or a sphere. Considering that Ant 3 is a cuboid, in this article, the example of the constructed target object being a cuboid is used for illustration. As Figure 7 and / or Figure 4 shown, the cuboid that surrounds Ant 3 and is located outside Ant 3 is the target object constructed for Ant 3 in this application.

[0113] S603: Obtain the reference position range of the target antenna based on the coverage position information of the target object.

[0114] In this application, in the coordinate system, the target object constructed for Ant 3 covers a certain position range, and this covered position range is used as the reference position range of the target antenna. From Figure 7 and / or Figure 4 it can be seen that since the constructed target object can enclose Ant 3, compared with the position range covered by Ant 3 itself in the coordinate system, the position range covered by the target object is larger. In this way, when the human body has not yet approached the antenna itself but only approaches the target object that encloses the antenna, the antenna transmission power can be reduced, and the harm of antenna radiation to the human body can be minimized to the greatest extent.

[0115] The solution for constructing the reference position of the antenna based on the requirements of SAR laws and regulations and the position of the antenna itself, as shown in S601 - S603, can minimize the harm of antenna radiation to the human body to the greatest extent.

[0116] Combined with Figure 7 shown, since a', b', c', and d' are values tested or measured under the requirements of SAR laws and regulations, the reference position range of the antenna constructed based on these values and the actual position of the antenna itself can be regarded as the SAR boundary field or the SAR field. From the perspectives of the right side, the front, the bottom, and the top of the target object, the SAR boundary field can be expressed as the following inequalities. Among them, x d is the coordinate of the point that constitutes the right side of the antenna in the coordinate system. y d is the coordinate of the point that constitutes the front of the antenna in the coordinate system. z d1 is the coordinate of the point that constitutes the bottom surface of the antenna in the coordinate system. z d2 is the coordinate of the point that constitutes the top surface of the antenna in the coordinate system.

[0117] SAR boundary inequality for the side edge: x ≤ a′ + x d

[0118] SAR boundary inequality for the front edge: y ≤ b′ + y d

[0119] SAR boundary inequality for the bottom: z ≤ d′ + z d1

[0120] SAR boundary inequality for the top: z ≤ c′ + z d2

[0121] Generally speaking, it is possible to determine whether to reduce the antenna transmission power by checking whether the position of the human body satisfies the above boundary inequalities. If the coordinates of the position of the human body are calculated as (x’, y’, z’) through the calculation of the ultrasonic wave and its reflected signal, then it is determined whether x’ satisfies the SAR boundary inequality, whether y’ satisfies the SAR boundary inequality of the front edge, whether z’ satisfies the SAR boundary inequality of the bottom, and whether z’ satisfies the SAR boundary inequality of the top. If x’ satisfies the SAR boundary inequality (x’ is less than or equal to a′ + x d ), y’ satisfies the SAR boundary inequality of the front edge (y’ is less than or equal to b′ + y d ), and z’ satisfies one of the SAR boundary inequalities of the bottom and the top (z’ is less than or equal to d′ + z d1 , or z’ is less than or equal to c′ + z d2 ), it is considered that the human body has entered the SAR boundary field of the antenna, and the radiation damage caused by the antenna to the human body can be reduced by reducing the transmission power of the antenna.

[0122] In this application, four antennas can form an antenna module, such as a WWAN antenna module. When the EC determines that the human body has entered the SAR boundary field of the antenna, it can notify the Bios to turn on the function of adjusting the transmission power of the antenna. When this function is enabled, the transmission power of the antenna that the human body has entered its SAR boundary field is reduced. Among them, if power adjustment is not required, the function of adjusting the transmission power of the antenna is usually turned off.

[0123] In this application, for each antenna of the electronic device, the foregoing solution is adopted to construct the target body for each antenna. The target body constructed for each antenna has a certain coverage range, and the positions within the coverage range are used as the reference position range corresponding to the antenna. That is, each antenna has its own SAR boundary field. During implementation, it is necessary to compare the SAR boundary field inequalities of each working antenna based on the position of the human body, so as to reduce the transmission power of the antenna whose position of the human body is within the SAR boundary field, while the transmission power of the antenna whose position of the human body is outside the SAR boundary field does not need to be reduced.

[0124] In this application, when the target strategy for reducing the transmission power of the antenna is determined, the reduction of the transmission power of the antenna can be a fixed value. Or, the closer the human body is to the antenna, the more it is reduced. However, it can be understood that the reduction of the transmission power of the antenna in this application should not affect the normal operation of the antenna.

[0125] In some embodiments, in this application, the solution for determining the target strategy based on the first position and the second position of at least one target antenna can also be as follows:

[0126] If the first position has a first distance relationship with the boundary of the reference position range of the target antenna, determine that the operating parameters of the target antenna are reduced by the first level value; if the first position has a second distance relationship with the boundary of the reference position range of the target antenna, determine that the operating parameters of the target antenna are reduced by the second level value; if the first position has a third distance relationship with the boundary of the reference position range of the target antenna, determine that the operating parameters of the target antenna are reduced by the third level value. Among them, the first level value, the second level value, and the third level value gradually decrease, and the difference between the first level value and the second level value is greater than the difference between the second level value and the third level value.

[0127] If the first level value, the second level value, and the third level value are regarded as the reduction amplitudes △p1, △p2, and △p3, then in this application, the values of △p1, △p2, and △p3 can be set to decrease in sequence. The boundary of the reference position range can be the case where the equal sign is taken in the foregoing SAR boundary field inequality. The first distance relationship can be that the position of the human body is outside the SAR boundary field and within a certain distance from the SAR boundary field. For example, for the coordinates (x’, y’, z’) of the position of the human body, if x’ does not satisfy the SAR boundary inequality (x’ is greater than a′ + x d ) and x’ is less than the first threshold, y’ does not satisfy the SAR boundary inequality of the Front edge (y’ is greater than b′ + y d ) and y’ is less than the second threshold, z’ does not satisfy the SAR boundary inequalities of the Bottom and Top (z’ is greater than d′ + z d1 and z’ is greater than c′ + zd2 ) If z' is less than the third threshold, it is considered that the position of the human body is outside the SAR boundary field and within a certain distance from the SAR boundary field. Among them, x' being less than the first threshold, y' being less than the second threshold, and z' being less than the third threshold indicate within a certain distance from the SAR boundary field. With respect to a relatively small reduction amplitude, the transmission power is reduced with a relatively large reduction amplitude △p1, so that the antenna uses the difference between the original power of the antenna and △p1 for normal signal transmission.

[0128] The second distance relationship can be that the position of the human body is on the edge of the SAR boundary field. For example, for the coordinates (x', y', z') of the position of the human body, if x' is equal to a′ + x d , y' is equal to b′ + y d and z' is equal to d′ + z d1 or z' is equal to c′ + z d2 Among them, it is considered that the position of the human body is on the edge of the SAR boundary field. With respect to relatively small and large reduction amplitudes, the transmission power is reduced with a medium reduction amplitude △p2, so that the antenna uses the difference between the original power of the antenna and △p2 for normal signal transmission.

[0129] The third distance relationship can be that the position of the human body is within the SAR boundary field. For example, for the coordinates (x', y', z') of the position of the human body, if x' is less than a′ + x d ), y' is less than b′ + y d and z' is less than d′ + z d1 , or z' is less than c′ + z d2 ), then it is considered that the human body is located within the SAR boundary field. With respect to relatively large and medium reduction amplitudes, the transmission power is reduced with a relatively small reduction amplitude △p3, so that the antenna uses the difference between the original power of the antenna and △p3 for normal signal transmission.

[0130] Considering that while trying to ensure minimizing the harm caused by antenna radiation to the human body, ensuring the normal signal transmission of the antenna, the difference between the first level value and the second level value can be made greater than the difference between the second level value and the third level value, that is, the power reduction amplitude outside the SAR field edge can be made greater than the power reduction amplitude within the SAR.

[0131] The above several different power reduction schemes can be regarded as a phased or case - by - case reduction scheme. If a person's movement trajectory is from outside the SAR boundary field of an antenna, to the edge of the SAR boundary field, and then to within the SAR boundary field, the antenna reduces the transmission power in turn with three reduction amplitudes △p1, △p2, and △p3, so as to reduce the adverse effects of antenna radiation on the human body by means of phased reduction of the antenna transmission power.
