An electronic device specific absorption rate adjustment method, an apparatus, an electronic device, and a storage medium according to embodiments of the present application are described below with reference to the drawings.
Fig. 1 is a schematic flowchart of a specific absorption rate adjustment method for an electronic device according to an embodiment of the present disclosure, where the electronic device may be a device with a communication function, such as a smart phone and a tablet computer.
As shown in fig. 1, the electronic device specific absorption rate adjustment method may include the steps of:
The radiation influence of the SAR value on the human body is generally related to the distance between the human body and the electronic device, and when the electronic device is close to the human body, for example, when a user uses the electronic device to perform voice call, the electronic device is generally close to the head of the user, and at this time, the SAR value has a greater radiation influence on the human body; when the electronic equipment is far away from the human body, the SAR value of the electronic equipment is slightly larger, and the SAR value cannot cause radiation influence on the human body. Therefore, the relative position between the electronic device and the user can be used as a condition for determining whether to adjust the specific absorption rate of the electronic device.
Therefore, in this embodiment, the relative position between the electronic device and the user may be detected in real time, or the relative position between the electronic device and the user may be periodically detected, and then whether the electronic device currently satisfies the specific absorption rate adjustment condition is determined according to the detected relative position between the electronic device and the user.
As an example, a distance sensor, a gravity sensor, an infrared sensor, or the like may be built in the electronic device, and a relative position between the electronic device and the user may be detected by the built-in sensor of the electronic device, where the relative position may be a distance between the electronic device and the user. And then, comparing the detected relative position with a preset distance threshold value to judge whether the electronic equipment meets the specific absorption rate adjustment condition currently. If the distance displayed by the relative position is larger than a preset distance threshold, judging that the specific absorption rate adjusting condition is not met currently; and if the distance displayed by the relative position is less than or equal to a preset distance threshold value, judging that the specific absorption rate adjustment condition is met currently.
And 102, if yes, acquiring the current working frequency band of the electronic equipment.
In this embodiment, when the electronic device currently satisfies the specific absorption rate adjustment condition, the current operating frequency band of the electronic device may be further obtained.
According to the mobile communication frequency division standard, different operators and different network systems use different network frequency bands, for example, the frequency bands used by the GSM900 system of the chinese mobile are uplink 890-909MHz and downlink 935-954 MHz; the frequency bands used by the GSM900 system of China Unicom are uplink 909-915MHz and downlink 954-960 MHz; the frequency bands used by the CDMA800 system of China telecom are uplink 825-835MHz and downlink 870-880 MHz; for FDD-LTE system, the frequency band used by China Unicom is uplink 1755 + 1765MHz, downlink 1850 + 1860MHz, the frequency band used by China Unicom is uplink 1765 + 1780MHz, and downlink 1860 + 1875 MHz; for the WLAN network, the operating frequency band is 2400-.
Therefore, as a possible implementation manner, in this embodiment, the current operating frequency band of the electronic device may be determined according to network access data in the electronic device. For example, when the electronic device accesses the WiFi network, it may be determined that the current operating frequency band of the electronic device is 2400-2483 MHz; for another example, when a user uses the electronic device to make a call, if the SIM card installed in the electronic device is a GSM card of china mobile, the current network access data of the electronic device is a 2G network of china mobile, so that it can be determined that the current operating frequency band of the electronic device is 890-909MHz at the uplink and 935-954MHz at the downlink.
A plurality of applications can be installed in the electronic equipment, some applications need network support when running, such as live-broadcast applications, shopping platforms and the like, and some applications do not need to rely on a network when running, such as click game applications. Therefore, applications installed in the electronic equipment can be divided into network applications and non-network applications, applications needing network support during running are the network applications, and applications not needing the network support during running are the non-network applications. As a possible implementation manner, in this embodiment, the current operating frequency band of the electronic device may be determined according to a currently running application type in the electronic device. As an example, if an application running in the electronic device is a voice call application, it may be determined that an application type of the application currently running in the electronic device is a non-network type application, and it is determined that a current operating frequency band of the electronic device is a voice call frequency band, and a specific operating frequency band may be further determined according to a type of a SIM card used by the electronic device; if the application currently running in the electronic device is the shopping platform, the application type of the application currently running in the electronic device is a network type application, and at this time, the current working frequency band of the electronic device may be further determined according to a network currently started by the electronic device, such as a WiFi network, a 3G network, a 4G network, or a 5G network.
And 103, adjusting the connection state of a tuning switch in the electronic equipment according to the current working frequency band of the electronic equipment, wherein the connection end of the tuning switch is respectively connected with an antenna body and a matching circuit in the electronic equipment.
In this embodiment, after the current operating frequency band of the electronic device is determined, the connection state of the tuning switch in the electronic device may be adjusted according to the current operating frequency band of the electronic device.
As an example, when the specific absorption rate is lowest in different operating frequency bands, a corresponding relationship between the operating frequency band and the connection state of the tuning switch may be preset and stored, and after the current operating frequency band of the electronic device is determined, the connection state of the tuning switch corresponding to the current operating frequency band is determined by querying the prestored corresponding relationship, and then the connection state of the tuning switch in the electronic device is adjusted according to the determined connection state of the tuning switch.
According to the method for adjusting the specific absorption rate of the electronic equipment, whether the electronic equipment meets the specific absorption rate adjustment condition currently is judged according to the relative position of the electronic equipment and a user currently, when the adjustment condition is met, the current working frequency band of the electronic equipment is obtained, and then the connection state of a tuning switch in the electronic equipment is adjusted according to the current working frequency band of the electronic equipment, so that the specific absorption rate is reduced. From this, realized adjusting specific absorption rate through tuning switch connection status among the adjustment electronic equipment, compare in prior art, need not to design two sets of antennas and print two-sided antenna and walk the line to reduce the occupation to circuit board layout area, reduced the antenna debugging degree of difficulty, promoted user experience.
To more clearly illustrate the specific implementation process of adjusting the connection state of the tuning switch in the electronic device according to the current operating frequency band of the electronic device in the foregoing embodiment, the present application provides another specific absorption rate adjustment method for the electronic device, and fig. 2 is a schematic flow chart of the another specific absorption rate adjustment method for the electronic device provided in the embodiment of the present application.
As shown in fig. 2, step 103 may include the following steps based on the embodiment shown in fig. 1:
The specific absorption rate can be used for measuring the influence degree of electromagnetic radiation of electronic equipment on a human body, and the specific meaning is that every kilogram of human tissue absorbs electromagnetic radiation energy by taking 6 minutes as timing. At present, two international universal specific absorption rate standards exist, one is the European standard, and the SAR value does not exceed 2 w/kg; one is the US standard, SAR value does not exceed 1.6 w/kg.
In this embodiment, a preset range of the specific absorption rate may be preset, for example, the preset range is set to be 0 to 1.6w/kg, 0.2w/kg to 1.5w/kg, etc., and the electronic device is controlled to operate in different operating frequency bands, and the connection state of the tuning switch is adjusted in each operating frequency band, so that the specific absorption rate of the electronic device is within the preset range, and the connection state of the tuning switch is recorded in each operating frequency band when the specific absorption rate of the electronic device is within the preset range.
In this embodiment, after the specific absorption rate test is performed on the electronic device to obtain the connection state of the corresponding tuning switch under each working frequency band when the specific absorption rate is within the preset range, the mapping relationship between the preset working frequency band and the connection state of the tuning switch can be determined according to the connection state of the corresponding tuning switch under each working frequency band.
In a possible implementation manner of the embodiment of the application, when the specific absorption rate of the electronic device is tested, the electronic device may be controlled to operate in different operating frequency bands, the connection state of the tuning switch is adjusted for each operating frequency band, on the basis of ensuring normal operation of the electronic device, the connection state of the tuning switch corresponding to the lowest SAR value in the operating frequency band is recorded, and the mapping relationship between the preset operating frequency band and the connection state of the tuning switch is determined according to the connection state of the tuning switch corresponding to each operating frequency band.
In a possible implementation manner of the embodiment of the present application, network frequency bands in different network systems may be further divided, and the same network frequency band is divided into three levels, i.e., for the network frequency band 2400 + 2483MHz of the WLAN, 2400 + 2425MHz may be divided into low frequency, 2425 + 2460MHz may be divided into intermediate frequency, and 2460 + 2483MHz may be divided into high frequency. And then, specific absorption rate test is carried out on the electronic equipment according to different network frequency bands and different frequency band grades of the same network frequency band, and finally the mapping relation between the different network frequency bands, the different network frequency band grades and the connection state of the tuning switch is obtained.
It should be noted here that the process of determining the mapping relationship between the preset operating frequency band and the connection state of the tuning switch, which is described in steps 201 to 202, may also be performed before step 101, and the present application is explained by taking the two steps performed before step 203 as an example, and is not limited to the present application. In specific implementation, the mapping relationship between the working frequency band and the connection state of the tuning switch may be preset, determined and stored in a memory of the electronic device before the electronic device leaves a factory, and when the method of the present application is executed, the mapping relationship between the working frequency band and the connection state of the tuning switch stored in the memory may be directly invoked.
And 203, determining a target connection state of the tuning switch corresponding to the current working frequency band according to a mapping relation between the preset working frequency band and the connection state of the tuning switch.
And 204, adjusting the connection state of the tuning switch in the electronic equipment to a target connection state.
In this embodiment, after the current working frequency band of the electronic device is obtained, a mapping relationship between the preset working frequency band and the connection state of the tuning switch may be queried, and a corresponding target connection state of the tuning switch may be determined according to the current working frequency band. And then, adjusting the connection state of the tuning switch in the electronic equipment to a target connection state, so that the SAR value of the electronic equipment is in a preset range, and the purpose of reducing the SAR value of the electronic equipment is achieved.
According to the specific absorption rate adjusting method for the electronic equipment, the specific absorption rate test is carried out on the electronic equipment to obtain the corresponding connection state of the tuning switch when the specific absorption rate of the electronic equipment is within the preset range under each working frequency band, and then the mapping relation between the preset working frequency band and the connection state of the tuning switch is determined according to the corresponding connection state of the tuning switch under each working frequency band, so that a foundation is laid for reducing the SAR value by adjusting the state of the tuning switch. The target connection state of the tuning switch corresponding to the current working frequency band is determined according to the mapping relation between the preset working frequency band and the connection state of the tuning switch, and then the connection state of the tuning switch in the electronic equipment is adjusted to the target connection state, so that the specific absorption rate is adjusted by adjusting the connection state of the tuning switch in the electronic equipment, the antenna debugging difficulty is reduced, and the user experience is improved.
Electronic devices are often equipped with multiple applications, which require different antenna gains. For example, for communication applications, audio/video playing applications, and the like, the requirement on antenna gain is high; and for click game type applications, the requirement on antenna gain is low. The antenna gain is used to quantitatively describe the degree to which the antenna concentrates the input power (i.e., energy), and it can be understood that the greater the antenna gain, the greater the SAR value of the electronic device. Therefore, in a possible implementation manner of the embodiment of the application, the SAR value of the electronic device may be adjusted by adjusting the antenna gain.
As a possible implementation manner, the mapping relationship between the pre-established operating frequency band and the connection state of the tuning switch may further include: and mapping relation between antenna gain and specific absorption rate, working frequency band and tuning switch connection state. Therefore, an embodiment of the present application provides another specific absorption rate adjustment method for an electronic device, and fig. 3 is a flowchart illustrating the another specific absorption rate adjustment method for the electronic device according to the embodiment of the present application.
As shown in fig. 3, on the basis of the embodiment shown in fig. 2, step 203 may include the following steps:
As an example, a distance sensor may be installed in the electronic device, and the distance sensor is utilized to determine a distance value between the electronic device and the user.
It can be understood that the smaller the value of the distance between the electronic device and the user, the better the SAR value of the electronic device. Therefore, in this embodiment, after the distance value between the electronic device and the user is determined, the corresponding target specific absorption rate may be determined according to the distance value.
As an example, different correspondence tables of distance values and specific absorption rates may be set and stored in advance, for example, as shown in table 1.
TABLE 1
| Distance value d (cm) | Maximum SAR value (w/kg) |
| d≤2 | 0.2 |
| 2<d≤10 | 0.5 |
| 10<d≤20 | 0.8 |
| … | … |
Furthermore, after the distance value between the current electronic equipment and the user is determined, the target specific absorption rate corresponding to the current distance value can be determined by inquiring the preset corresponding relation table. For example, if the current distance value is 13cm, it can be determined that the corresponding target specific absorption rate does not exceed 0.8w/kg by referring to table 1.
In practical applications, there may be a plurality of tuning switch connection states that satisfy the same specific absorption rate, for example, under a 4G network and a WLAN network, respectively, because the network frequency bands of the 4G network and the WLAN network are different, the connection states of the tuning switches are different when the SAR values of the electronic device under the two networks are the same, and the corresponding antenna gains are also different. Thus, in this embodiment, after the target specific absorption rate is determined, the corresponding plurality of tuning switch candidate connection states may be determined according to the target specific absorption rate.
And step 304, selecting a target connection state of the tuning switch from a plurality of candidate connection states of the tuning switch according to the type of the application currently running in the electronic equipment.
Different applications have different requirements on antenna gain, for example, for communication applications, audio/video playing applications and the like, because network support is required during application operation, the requirements on antenna gain of the applications are higher; for click game applications, the requirement on antenna gain is low because the applications do not need to rely on a network during running. Therefore, in this embodiment, after determining the plurality of connection state candidates of the tuning switch corresponding to the target specific absorption rate, the target connection state of the tuning switch may be further selected from the plurality of connection state candidates of the tuning switch according to the type of the application currently running in the electronic device.
For example, assuming that an application currently running in the electronic device is a click mini-game and the application does not need to rely on a network during running, a tuning switch candidate connection state with the smallest antenna gain may be selected from the multiple tuning switch candidate connection states as a tuning switch target connection state. Assuming that the currently running application in the electronic device is a live video application and the application needs to rely on a good network during running to avoid the occurrence of blocking during live broadcasting, the candidate connection state of the corresponding tuner with the largest antenna gain can be selected from the candidate connection states of the plurality of tuners to serve as the target connection state of the tuner.
Furthermore, after the target connection state of the tuning switch is selected, the connection state of the tuning switch in the electronic equipment can be adjusted to the target connection state, so that the specific absorption rate of the electronic equipment is matched with the distance value between the current electronic equipment and the user, and the specific absorption rate of the electronic equipment is adjusted by adjusting the antenna gain under the condition of meeting the normal service requirement.
In the method for adjusting the specific absorption rate of the electronic device, the distance value between the current electronic device and a user is determined, the corresponding target specific absorption rate is determined according to the distance value, and then the connection states of multiple tuning switches with different antenna gains are determined according to the target specific absorption rate, and then the target connection state of the tuning switch is selected from the connection states of the multiple tuning switches according to the application type currently running in the electronic device, so as to adjust the connection state of the tuning switch to the target connection state.
