[0025] The antenna transmit power adjustment method, device, equipment and medium provided by the embodiments of the present application will be described in detail below with reference to the drawings, specific embodiments and application scenarios.

[0026] It should be noted that the antenna transmission power adjustment method provided in the embodiments of the present application can be executed by a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted electronic device, or the like. The antenna transmission power adjustment method is executed by an electronic device as an execution subject in some embodiments of the present application, and the antenna transmission power adjustment method provided in the embodiments of the present application is described.

[0027] The electronic device in the embodiments of the present application includes a speaker module, a specific absorption rate sensor, and an antenna module.

[0028] Figure 1 FIG. 1 is a flowchart of the antenna transmission power adjustment method provided in some embodiments of the present application. The antenna transmission power adjustment method includes the following steps:

[0029] In step 101, when the speaker module and the specific absorption rate sensor are both in a working state, a first capacitance value collected by the specific absorption rate sensor through a first data collection time slot and a second capacitance value collected by the specific absorption rate sensor through a second data collection time slot are obtained. The first data collection time slot and the second data collection time slot are time slots for collecting capacitance values by the specific absorption rate sensor, and the first data collection time slot and the second data collection time slot are different collection time slots.

[0030] For example, the first data collection time slot is from the 0th second to the 1st second, from the 2nd second to the 3rd second,..., from the 2nth second to the 2n+1th second, and the second data collection time slot is from the 1st second to the 2nd second, from the 3rd second to the 4th second,..., from the 2n-1th second to the 2nth second, where n is a natural number.

[0031] In step 102, the transmission power of the antenna module is adjusted according to the first capacitance value and the second capacitance value.

[0032] In the embodiments of the present application, when the speaker module and the specific absorption rate sensor are both in a working state, the first capacitance value collected by the specific absorption rate sensor through the first data collection time slot and the second capacitance value collected by the specific absorption rate sensor through the second data collection time slot are obtained. The first data collection time slot and the second data collection time slot are time slots for collecting capacitance values by the specific absorption rate sensor, and the first data collection time slot and the second data collection time slot are different collection time slots. The transmission power of the antenna module is adjusted according to the first capacitance value and the second capacitance value. In this way, the specific absorption rate sensor collects capacitance values through two data collection time slots, and the transmission power of the antenna module is adjusted according to the capacitance values collected by the specific absorption rate sensor through the two data collection time slots, which can improve the accuracy of adjusting the transmission power of the antenna module and reduce the probability of adverse effects on human health caused by the high antenna transmission power of the electronic device when the human body is close to the electronic device.

[0033] In some embodiments of the present application, step 102 can include: increasing the transmission power of the antenna module when the first capacitance value is less than or equal to the first capacitance threshold and the second capacitance value is less than or equal to the second capacitance threshold; and decreasing the transmission power of the antenna module when the first capacitance value is greater than the first capacitance threshold or the second capacitance value is greater than the second capacitance threshold.

[0034] In some embodiments of the present application, the first capacitance threshold and the second capacitance threshold in the embodiments of the present application can be set according to actual needs, wherein the first capacitance threshold and the second capacitance threshold can be the same or different.

[0035] For example, when the loudspeaker module and the specific absorption rate sensor are in a working state at the same time, when the first capacitance value C1 collected by the specific absorption rate sensor through the first data collection time slot is greater than the first capacitance threshold A1 and the second capacitance value C2 collected through the second data collection time slot is less than or equal to the second capacitance threshold A2, it is determined that the user is close to the electronic device through the first capacitance value C1 and that the user is away from the electronic device through the second capacitance value C2, indicating that there is interference in the data collection channel, at this time, since it is determined that the user is close to the electronic device through the first capacitance value C1, the transmission power of the antenna module is reduced.

[0036] For example, when the loudspeaker module and the specific absorption rate sensor are in a working state at the same time, when the second capacitance value C2 collected by the specific absorption rate sensor through the second data collection time slot is greater than the second capacitance threshold A2 and the first capacitance value C1 collected through the first data collection time slot is less than or equal to the first capacitance threshold A1, it is determined that the user is away from the electronic device through the first capacitance value C1 and that the user is close to the electronic device through the second capacitance value C2, indicating that there is interference in the data collection channel, at this time, since it is determined that the user is close to the electronic device through the second capacitance value C2, the transmission power of the antenna module is reduced.

[0037] For example, when the loudspeaker module and the specific absorption rate sensor are in a working state at the same time, when the first capacitance value C1 collected by the specific absorption rate sensor through the first data collection time slot is greater than the first capacitance threshold A1 and the second capacitance value C2 collected through the second data collection time slot is greater than the second capacitance threshold A2, it is determined that the user is close to the electronic device through the first capacitance value C1 and that the user is close to the electronic device through the second capacitance value C2, indicating that there is no interference in the data collection channel, at this time, since it is determined that the user is close to the electronic device through the first capacitance value C1 and the second capacitance value C2, the transmission power of the antenna module is reduced.

[0038] Exemplarily, when the loudspeaker module and the specific absorption rate sensor are both in a working state, when a first capacitance value C1 collected by the specific absorption rate sensor through a first data collection time slot is less than or equal to a first capacitance threshold A1, and a second capacitance value C2 collected through a second data collection time slot is less than or equal to a second capacitance threshold A2, it is determined that the user is close to the electronic device through the first capacitance value C1 and the second capacitance value C2, which indicates that there is no interference in the data collection channel, and at this time, since it is determined that the user is away from the electronic device through the first capacitance value C1 and the second capacitance value C2, the transmission power of the antenna module is increased.

[0039] It should be noted that the closer the distance between the human body and the electronic device, the greater the capacitance value collected by the specific absorption rate sensor.

[0040] In some embodiments of the present application, before step 101, the antenna transmission power adjustment method provided by the embodiments of the present application can further include: determining a first sampling rate corresponding to the first data collection time slot and a second sampling rate corresponding to the second data collection time slot according to the pulse width modulation frequency of the loudspeaker module, wherein the first sampling rate and the second sampling rate are the frequencies at which the specific absorption rate sensor samples the capacitance value; and at least one of the first sampling rate and the second sampling rate is an odd multiple of the pulse width modulation frequency.

[0041] Exemplarily, assuming that the PWM frequency of the loudspeaker module is 1.5KHz, the determined first sampling rate is 0.5KHz, and the second sampling rate is 1KHz, the PWM frequency of the loudspeaker module is 3 times the first sampling rate, and the PWM frequency of the loudspeaker module is 1.5 times the second sampling rate, that is, the PWM frequency of the loudspeaker module is an odd multiple of the first sampling rate, and the PWM frequency of the loudspeaker module is not an odd multiple of the second sampling rate.

[0042] Exemplarily, assuming that the PWM frequency of the loudspeaker module is 1.5KHz, the determined first sampling rate is 1KHz, and the second sampling rate is 0.3KHz, the PWM frequency of the loudspeaker module is 1.5 times the first sampling rate, and the PWM frequency of the loudspeaker module is 5 times the second sampling rate, that is, the PWM frequency of the loudspeaker module is not an odd multiple of the first sampling rate, and the PWM frequency of the loudspeaker module is an odd multiple of the second sampling rate.

[0043] Exemplarily, assuming that the PWM frequency of the loudspeaker module is 1.5KHz, the determined first sampling rate is 1KHz, and the second sampling rate is 0.75KHz, the PWM frequency of the loudspeaker module is 1.5 times the first sampling rate, and the PWM frequency of the loudspeaker module is 2 times the second sampling rate, that is, the PWM frequency of the loudspeaker module is neither an odd multiple of the first sampling rate nor an odd multiple of the second sampling rate.

[0044] In the embodiments of the present application, by determining that the odd multiple of at least one of the two sampling rates is different from the pulse width modulation frequency of the loudspeaker module, it can be avoided that at least one of the two sampling rates is interfered by the loudspeaker module, and thus the accuracy of adjusting the transmission power of the antenna module can be improved, and the probability of causing adverse effects on human health due to the high transmission power of the antenna of the electronic device when the human body is close to the electronic device can be reduced.

[0045] In some embodiments of the present application, two single-chip circuit boards for testing the PWM frequency of the loudspeaker module can be arranged on the production line of the electronic device, and the two single-chip circuit boards are connected with the host board through an Inter-Integrated Circuit (I2C) transmission protocol, and the two single-chip circuit boards are also connected with the loudspeaker of the electronic device under test.

[0046] The host board controls the loudspeaker to work through a Universal Asynchronous Receiver / Transmitter (UART), and the two single-chip circuit boards measure the PWM frequency of the loudspeaker respectively and send the measured two PWM frequencies to the host board through the I2C transmission protocol. The host board judges whether the difference between the two PWM frequencies is less than a frequency threshold value and whether the two PWM frequencies are all within a given frequency range, and if so, the average of the two PWM frequencies is taken as the PWM frequency of the loudspeaker, and the PWM frequency of the loudspeaker is written into the electronic device.

[0047] In some embodiments of the present application, n SAR sampling rates can be set in advance, and the n SAR sampling rates set in advance are compared with the PWM frequency of the loudspeaker written into the electronic device in sequence, when the PWM frequency of the loudspeaker is an odd multiple of the i th SAR sampling rate, it is judged whether the PWM frequency of the loudspeaker is an odd multiple of the i+1 th SAR sampling rate, and when the loudspeaker frequency is not an odd multiple of the i+1 th SAR sampling rate, the sampling rate of the data acquisition time slot is set to the i+1 th SAR sampling rate, wherein n is a positive integer, and i is a positive integer less than or equal to n.

[0048] In some embodiments of the present application, step 102 can include: determining whether the first sampling rate corresponding to the first data acquisition time slot and the second sampling rate corresponding to the second data acquisition time slot are interfered by the loudspeaker module according to the pulse width modulation frequency of the loudspeaker module, to obtain a first interference result; determining whether the first capacitance value and the second capacitance value are interfered by the loudspeaker module, to obtain a second interference result; and adjusting the transmission power of the antenna module according to the first interference result and the second interference result.

[0049] In some embodiments of the present application, according to the pulse width modulation frequency of the loudspeaker module, it is determined whether the first sampling rate corresponding to the first data acquisition time slot is disturbed by the loudspeaker module and whether the second sampling rate corresponding to the second data acquisition time slot is disturbed by the loudspeaker module, to obtain a first interference result, which can include: in the case that the difference between the odd multiple of the sampling rate corresponding to the third data acquisition time slot and the pulse width modulation frequency is within the preset frequency range, it is determined that the sampling rate corresponding to the third data acquisition time slot is disturbed by the loudspeaker module, wherein the third data acquisition time slot is the first data acquisition time slot or the second data acquisition time slot; in the case that the difference is not within the preset frequency range, it is determined that the sampling rate corresponding to the third data acquisition time slot is not disturbed by the loudspeaker module.

[0050] In some embodiments of the present application, the preset frequency range can be set according to actual needs, for example, the preset frequency range is -35KHz to 35KHz.

[0051] In some embodiments of the present application, when at least one of the odd multiples of the sampling rate corresponding to the third data acquisition time slot and the pulse width modulation frequency of the loudspeaker is within the preset frequency range, it is determined that the sampling rate corresponding to the third data acquisition time slot is disturbed by the loudspeaker module; when all the odd multiples of the sampling rate corresponding to the third data acquisition time slot and the pulse width modulation frequency of the loudspeaker are not within the preset frequency range, it is determined that the sampling rate corresponding to the third data acquisition time slot is not disturbed by the loudspeaker module.

[0052] Figure 2 is a flowchart of determining the interference state of the sampling rate provided by some embodiments of the present application; the flow of determining whether the sampling rate is disturbed includes the following steps:

[0053] Step 201: judge whether the difference between the odd multiple of the sampling rate corresponding to the data acquisition time slot and the pulse width modulation frequency of the loudspeaker is within the preset frequency range, if yes, execute step 202, if not, execute step 203;

[0054] Step 202: determine that the sampling rate corresponding to the data acquisition time slot is disturbed by the loudspeaker module;

[0055] Step 203: determine that the sampling rate corresponding to the data acquisition time slot is not disturbed by the loudspeaker module.

[0056] Exemplarily, it is assumed that the sampling rate corresponding to the first data acquisition time slot is 30KHz, the pulse width modulation frequency of the loudspeaker is 100KHz, and the preset frequency range is -35KHz to 35KHz.

[0057] If the difference between the sampling rate of 30kHz corresponding to the first data acquisition time slot and the pulse width modulation frequency of the speaker (100kHz) is -10kHz, and this difference is within the preset frequency range of -35kHz to 35kHz, then it is determined that the sampling rate corresponding to the first data acquisition time slot is being interfered with by the speaker module.

[0058] For example, assume that the sampling rate of the first data acquisition time slot is 60KHz, the pulse width modulation frequency of the speaker is 100KHz, and the preset frequency range is -35KHz to 35KHz.

[0059] If the difference between (2n-1) times the sampling rate of 60KHz corresponding to the first data acquisition time slot and the pulse width modulation frequency of 100KHz of the speaker is not within the preset frequency range of -35KHz to 35KHz, then it is determined that the sampling rate corresponding to the first data acquisition time slot is not interfered with by the speaker module, where n is a positive integer.

[0060] In some embodiments of this application, determining whether the first capacitance value is interfered with by the speaker module and whether the second capacitance value is interfered with by the speaker module to obtain a second interference result may include: dividing multiple capacitance values ​​acquired through the fourth data acquisition time slot into M groups, wherein each group of capacitance values ​​includes N capacitance values, wherein the fourth data acquisition time slot is either the first data acquisition time slot or the second data acquisition time slot, and M and N are positive integers; calculating the absolute value of the difference between the last capacitance value in the i-th group of capacitance values ​​in the M groups and the values ​​in the i-th group, wherein i is a positive integer less than or equal to N; calculating the sum of the absolute values ​​to obtain the group data of the i-th group of capacitance values; if the fourth condition is met, determining that the first capacitance value is not interfered with by the speaker module and the second capacitance value is interfered with by the speaker module; if the fifth condition is met, determining that the second capacitance value is not interfered with by the speaker module and the first capacitance value is interfered with by the speaker module. The fourth condition includes: all M groups of data in the first data acquisition time slot are less than the first threshold, and the difference between the M groups of data in the second data acquisition time slot and the M groups of data in the first data acquisition time slot is greater than the first threshold; the fifth condition includes: some M groups of data in the first data acquisition time slot are less than the first threshold, all M groups of data in the second data acquisition time slot are less than the first threshold, and the difference between the M groups of data in the first data acquisition time slot and the M groups of data in the second data acquisition time slot is greater than the first threshold.

[0061] For example, assume that each group of capacitance values ​​includes 8 capacitance values.

[0062] The capacitance values ​​acquired through the first data acquisition time slot are d in sequence. 1-1 d 1-2 ... d 1-n The capacitance values ​​acquired through the second data acquisition time slot are d in sequence.2-1 , d 2-2 , …, d 2-n .

[0063] d 1-1 to d 1-8 are divided into a group, d 1-9 to d 1-16 are divided into a group, …, that is, d 1-8M-7 to d 1-8M are divided into a group, wherein M is a positive integer.

[0064] d 2-1 to d 2-8 are divided into a group, d 2-9 to d 2-16 are divided into a group, …, that is, d 2-8M-7 to d 2-8M are divided into a group.

[0065] The group data of the i-th group of capacitance values in the capacitance values collected by the first data collection time slot is denoted as D 1-i , the group data of the i-th group of capacitance values in the capacitance values collected by the second data collection time slot is denoted as D 2-i , wherein i is a positive integer less than or equal to M, then

[0066] D 1-i = |d 1-8i -d 1-8i-7 | + |d 1-8i -d 1-8i-6 | + |d 1-8i -d 1-8i-5 | + |d 1-8i -d 1-8i-4 | + |d 1-8i -d 1-8i-3 | + |d 1-8i -d 1-8i-2 | + |d 1-8i -d 1-8i-1 |;

[0067] D 2-i = |d 2-8i -d 2-8i-7 | + |d 2-8i -d 2-8i-6 | + |d 2-8i -d 2-8i-5 | + |d 2-8i -d 1-8i-4 | + |d 2-8i -d 1-8i-3 | + |d 2-8i -d 1-8i-2 | + |d 2-8i -d 2-8i-1 |。

[0068] When D 1-1 , D 1-2 , … D 1-M are all less than the first threshold value and the difference between D 2-i and D 1-i is all greater than the first threshold value, it is determined that the capacitance value collected by the second data collection time slot is not disturbed by the loudspeaker module, and the capacitance value collected by the first data collection time slot is disturbed by the loudspeaker module.

[0069] When D 1-1 , D 1-2 , … D 1-M are partially less than the first threshold value, D 2-1 , D 2-2 , … D 2-M are all less than the first threshold value, and the difference between D 1-i and D 2-i is all greater than the first threshold value, it is determined that the capacitance value collected by the first data collection time slot is not disturbed by the loudspeaker module, and the capacitance value collected by the second data collection time slot is disturbed by the loudspeaker module.

[0070] Figure 3 is a flowchart of determining the interference state of the capacitance value provided by some embodiments of the present application. The flow of determining whether the capacitance value is disturbed includes the following steps:

[0071] Step 301: Obtain a plurality of capacitance values collected by a specific absorption rate sensor through a first data collection time slot and a plurality of capacitance values collected through a second data collection time slot;
