The following describes the control method provided by the embodiments of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Referring to fig. 1, a flowchart illustrating steps of a control method according to an embodiment of the present application is shown, where the control method is applicable to an electronic device that can establish a communication connection with a digital headset. As shown in fig. 1, the method may specifically include:
step 101: and acquiring sampling parameters of the transmitted audio signal under the condition that the electronic equipment establishes communication connection with the digital earphone.
In this embodiment of the present application, the electronic device may include, but is not limited to, at least one of a mobile phone, a tablet computer, and a wearable device, and the specific type of the electronic device may not be limited in this embodiment of the present application. The digital headset is a headset product that uses a digital interface to directly communicatively connect with an electronic device. The digital headset may include, but is not limited to, a design of a carry-on ear bud and a headset.
In practical applications, the electronic device may be provided with a data line interface, where the data line interface may include, but is not limited to, at least one of a Universal Serial Bus (USB) interface or a lightning interface, and the specific type of the data line interface may not be limited in this application. And under the condition that the digital earphone is inserted into the data line interface, the communication connection between the electronic equipment and the digital earphone can be established.
In the embodiment of the present application, under the condition that the electronic device establishes a communication connection with the digital headset, a sampling parameter of an audio signal transmitted by the digital headset may be obtained.
Referring to fig. 2, which shows a hardware structure diagram of the electronic device and the digital headset according to the embodiment of the present disclosure, as shown in fig. 2, the electronic device 100 may include a processor 101, and first audio codec chips 102 and 103, where one end of the first audio codec chip 102 is electrically connected to the processor 101, and the other end is electrically connected to the data line interface 103. The digital earphone 200 may include a receiver 201, a second audio codec chip 202, and a second data line interface 203, wherein one end of the second audio codec chip 202 is electrically connected to the receiver 201, and the other end is electrically connected to the second data line interface 203. In the case where the second data line interface 203 of the digital headset 200 is inserted into the first data line interface 103 of the electronic device 100, a communication connection between the electronic device 100 and the digital headset 200 may be established.
In a specific application, in a case that the electronic device 100 establishes a communication connection with the digital headset 200, the first audio codec chip 102 on the electronic device 100 may be used to acquire sampling parameters of an audio signal transmitted by the digital headset 200.
In particular, the sampling parameters of the audio signal may include, but are not limited to, a sampling size and a sampling frequency. In practical applications, the sampling parameters of the audio signal are related to the audio quality, and the higher the audio quality of the audio signal is, the larger the sampling parameters are. And the larger the sampling parameter is, the larger the audio data which needs to be transmitted between the electronic device and the digital headset is, the higher the data transmission rate between the electronic device and the digital headset is, and the larger the influence on the cellular communication quality of the electronic device is.
For example, in the case where a user listens to high-quality music or high-definition movies using the digital headphones, the sampling frequency of the audio signal may reach 24bit and 192Khz and two channels due to the high quality of the audio signal. And in the scene that the user uses the digital earphone to watch short video or make a call, the sampling parameter of the audio signal is correspondingly low due to the low quality of the audio signal.
Step 102: and acquiring a theoretical receiving level and an actual receiving level of the radio frequency signal.
In this embodiment, in the case that the electronic device establishes a communication connection with the digital headset, the processor 101 in the electronic device may further be configured to obtain a theoretical reception level and an actual reception level of the radio frequency signal.
Specifically, the radio frequency signal may be received by an antenna of the electronic device, demodulated by a modem after low noise amplification, and identified by a processor of the electronic device after digital-to-analog conversion to an actual reception level R1 at which the radio frequency signal is received. The theoretical received level of the rf signal may be calculated according to the processor 101 of the electronic device.
In an optional embodiment of the present application, the method for obtaining the theoretical reception level of the radio frequency signal may specifically include the following sub-steps:
sub-step S11: a first transmit level of the electronic device, a second transmit level of the base station, and a first receive level are obtained.
In the embodiment of the present application, in the case that the user uses the cellular network of the electronic device and the digital headset at the same time, the electronic device may obtain the respective transmission level and reception level through communication with the base station, so as to calculate the theoretical reception level of the radio frequency signal without interference.
Specifically, based on the communication connection between the electronic device and the base station, the processor 101 of the electronic device may obtain the first transmission level P1 of the electronic device, and the second transmission level P2 and the first reception level R3 of the base station.
Substep S12: and determining the theoretical receiving level of the radio frequency signal according to the first transmitting level, the second transmitting power level and the first receiving level.
In the embodiment of the present application, after the first transmission level P1 of the electronic device, and the second transmission level P2 and the first reception level R3 of the base station are obtained, the uplink path loss L2 and the downlink path loss L1 of the radio frequency signal may be calculated accordingly.
Specifically, the uplink path loss L2 and the downlink path loss L1 of the radio frequency signal can be calculated according to the following formulas:
l2 ═ P1-R3 (formula 1)
L1 ═ P2-R2 (formula 2)
Wherein R2 is a theoretical received level of the radio frequency signal received by the electronic device. In practical applications, the uplink path loss L2 and the downlink path loss L1 of the rf signal are substantially equal under the condition of default no frequency selective fading, that is, the uplink path loss L2 and the downlink path loss L1 are substantially equal
L2 ≈ L1 (equation 3)
From equation 1, equation 2 and equation 3, a calculation equation for the theoretical received level R2 of the radio frequency signal may be determined:
r2 ═ P2-P1+ R3 (formula 4)
In the embodiment of the application, after the theoretical reception level R2 and the actual reception level R1 of the radio frequency signal are obtained, whether the radio frequency signal is a strong signal or a weak signal can be determined according to the theoretical reception level R2. Furthermore, the processor 101 of the electronic device may compare the actual reception level R1 with the theoretical reception level R2 and determine whether there is interference with the transmission of the radio frequency signal of the electronic device by the digital headset based on the difference between the actual reception level R1 and the theoretical reception level R2.
Step 103: and processing the audio signal according to the sampling parameter, the theoretical receiving level and the actual receiving level.
In the embodiment of the present application, the transmission quality requirement of the audio signal and the influence of the audio signal on the cellular communication quality may be determined according to the sampling parameter. From the theoretical reception level R2 and the actual reception level R1, it can be determined whether the radio frequency signal is of the type and whether the radio frequency signal is subject to interference. According to the transmission quality requirement of the audio signal, the influence of the audio signal on the cellular communication quality, the type of the radio frequency signal and the condition whether the radio frequency signal is interfered, the audio signal is processed, the influence of the audio signal on the communication quality of the lower antenna can be reduced on the premise of meeting the transmission quality of the audio signal, and therefore the cellular communication quality of the electronic equipment is improved.
In summary, the control method according to the embodiment of the present application may include at least the following advantages:
in the embodiment of the application, under the condition that the electronic equipment and the digital earphone establish communication connection, sampling parameters of transmitted audio signals can be acquired; acquiring a theoretical receiving level and an actual receiving level of the radio frequency signal; and processing the audio signal according to the sampling parameter, the theoretical receiving level and the actual receiving level so as to reduce the influence of the audio signal on the communication quality of a lower antenna, thereby improving the cellular communication quality of the electronic equipment.
Referring to fig. 3, a flowchart illustrating steps of another control method according to an embodiment of the present application is shown, and as shown in fig. 3, the control method may specifically include the following data:
step 301: and acquiring sampling parameters of the transmitted audio signal under the condition that the electronic equipment establishes communication connection with the digital earphone.
In the embodiment of the present application, the specific implementation process of step 301 may refer to step 101 in the foregoing embodiment, which is not described herein again.
Step 302: and acquiring a theoretical receiving level and an actual receiving level of the radio frequency signal.
In the embodiment of the present application, the specific implementation process of step 302 may refer to step 102 in the foregoing embodiment, which is not described herein again.
Step 303: and determining the audio type of the audio signal according to the sampling parameter.
In the embodiment of the present application, the sampling parameters of the audio signal may include, but are not limited to, a sampling size and a sampling frequency. The sampling parameters of the audio signal are related to the audio quality, and therefore, according to the sampling parameters, the audio type of the audio signal can be determined.
Specifically, the audio types may include a first audio type and a second audio type, the first audio type may be an audio type with higher audio quality, and the second audio type may specifically be an audio type with lower audio quality.
For example, in the case of listening to high-quality music or high-definition movies using the digital headphones, the sampling frequency of the audio signal may reach 24bit and 192Khz and two channels due to the high quality of the audio signal, and at this time, the type of the audio model may be determined to be the first audio type according to the sampling parameters. And in the scene that the user uses the digital earphone to watch short videos or make a call, because the quality of the audio signal is low, the sampling parameter of the audio signal is correspondingly low, and at the moment, the audio type can be determined to be the second audio type.
Step 304: and processing the audio signal corresponding to the audio type according to the audio type, the theoretical receiving level and the actual receiving level.
In the embodiment of the present application, according to the audio type, a transmission quality requirement of the audio signal and an influence of the audio signal on the cellular communication quality may be determined. From the theoretical reception level R2 and the actual reception level R1, it can be determined whether the radio frequency signal is of the type and whether the radio frequency signal is subject to interference. According to the transmission quality requirement of the audio signal, the influence of the audio signal on the cellular communication quality, the type of the radio frequency signal and the condition whether the radio frequency signal is interfered, the audio signal is processed, the influence of the audio signal on the communication quality of the lower antenna can be reduced on the premise of meeting the transmission quality of the audio signal, and therefore the cellular communication quality of the electronic equipment is improved.
Optionally, the method for processing the audio signal corresponding to the audio type according to the audio type, the theoretical reception level, and the actual reception level may specifically include the following sub-steps:
at step S21: and determining the interference condition of the transmission of the audio signal to the transmission of the radio frequency signal based on the theoretical receiving level and the actual receiving level under the condition that the audio type is the first audio type.
In the embodiment of the present application, when the audio type is the first audio type, it may be considered that the audio quality of the audio signal is higher, the transmission rate of the audio signal is faster, and the influence on the quality of cellular communication of the electronic device is larger. In this case, an interference situation of the transmission of the audio signal with the transmission of the radio frequency signal may be determined based on the theoretical reception level R2 and the actual reception level R1.
Substep S22: and determining that the audio signal has interference on the radio frequency signal under the condition that the theoretical receiving level is smaller than a first threshold value and the difference value between the actual receiving level and the theoretical receiving level is larger than a second threshold value.
In the embodiment of the present application, whether the radio frequency signal is a strong signal or a weak signal is determined according to the theoretical reception level R2. In the case where the theoretical reception level R2 is less than the first threshold, the radio frequency signal may be considered to be a weak signal, and when cellular communication is performed using the weak signal, the communication quality is generally poor. In the case where the theoretical reception level R2 is greater than or equal to the first threshold, the radio frequency signal may be considered to be a strong signal, and when cellular communication is performed using the strong signal, the communication quality is generally good.
Specifically, the first threshold may be a threshold for determining the strength of the radio frequency signal, and a specific value of the first threshold may be set according to an actual situation. For example, the first threshold may be-80 dbm, the radio frequency signal may be considered to be a weak signal in the case of a theoretical reception level R2< -80dbm, and the radio frequency signal may be considered to be a strong signal in the case of a theoretical reception level R2> -80dbm or R2 ═ 80 dbm.
In a specific application, when the radio frequency signal is a strong signal, the interference of the audio signal to the radio frequency signal is negligible due to the good communication quality of the radio frequency signal. Under the condition that the radio-frequency signal is a weak signal, the influence of the interference of the audio signal on the radio-frequency signal on the communication quality is large due to the poor communication quality of the radio-frequency signal.
In the embodiment of the present application, due to the interference of the audio signal of the digital headset to the radio frequency signal, the actual reception level R1 and the theoretical reception level R2 of the radio frequency signal of the electronic device tend to be different. Therefore, based on the difference between the theoretical reception level R2 and the actual reception level R1, it can be determined whether the radio frequency signal is interfered. Specifically, in the case that the difference between the actual receiving level R1 and the theoretical receiving level R2 is greater than the second threshold, it can be considered that the audio signal has a larger interference to the current frequency band of the radio frequency signal. In the case that the difference between the actual reception level R1 and the theoretical reception level R2 is less than or equal to the second threshold, the interference of the audio signal to the current frequency band of the radio frequency signal may be considered to be small and may be ignored.
Specifically, the second threshold may be a threshold for determining an influence of the audio signal on the communication quality of the radio frequency signal, and a specific value of the second threshold may be set according to an actual situation. For example, the second threshold may be 6 db. Thus, at the difference R1-R2>6db between the actual reception level R1 and the theoretical reception level R2, it can be considered that the interference of the audio signal to the current frequency band of the radio frequency signal is large.
In the case that the difference R1-R2 between the actual reception level R1 and the theoretical reception level R2 is <6db or R1-R2 is 6db, it can be considered that the interference of the audio signal to the current frequency band of the radio frequency signal is small and negligible.
In the embodiment of the present application, when the theoretical reception level R2 is greater than or equal to the first threshold, the radio frequency signal may be considered as a strong signal, and when cellular communication is performed using the strong signal, the communication quality is generally good, in which case, the interference of the audio signal to the radio frequency signal is negligible. In the case that the difference between the actual reception level R1 and the theoretical reception level R2 is less than or equal to the second threshold, the interference of the audio signal to the current frequency band of the radio frequency signal may be considered to be small and may be ignored. Therefore, only in the case that the theoretical receiving level is smaller than a first threshold and the difference between the actual receiving level and the theoretical receiving level is greater than a second threshold, it can be determined that the audio signal interferes with the radio frequency signal, and the audio signal transmitted by the digital headset has a large influence on the communication quality of the radio frequency signal.
Substep S23: performing interference reduction processing on the audio signal in the presence of interference on transmission of the radio frequency signal by transmission of the audio signal.
In the embodiment of the application, under the condition that the transmission of the audio signal of the digital earphone has interference to the transmission of the radio frequency signal, the interference reduction processing can be performed on the audio signal so as to reduce the interference of the audio signal to the radio frequency signal and reduce the influence of the audio signal on the communication quality of the lower antenna, thereby improving the cellular communication quality of the electronic equipment.
Specifically, the interference reduction processing may specifically include: reducing the sampling parameters of the audio signal. I.e. the sample size and the sample frequency of the audio signal is reduced. Thus, the transmission rate of the audio signal can be reduced, and further, the interference of the audio signal to the radio frequency signal can be reduced.
In practical applications, after reducing the sampling size and the sampling frequency of the audio signal, the interference of the audio signal to the radio frequency signal is also reduced in response, and accordingly, the difference between the actual reception level R1 and the theoretical reception level R2 of the radio frequency signal is also reduced. In order to guarantee the audio quality of the audio signal as much as possible, the sampling size and the sampling frequency of the audio signal may be adjusted with reference to the difference between the actual reception level R1 and the theoretical reception level R2.
In a specific application, when the difference between the actual receiving level R1 and the theoretical receiving level R2 is reduced to be less than the second threshold, it can be considered that the transmission of the audio signal has less interference to the transmission of the radio frequency signal, and therefore, the continuous reduction of the sampling size and the sampling frequency of the audio signal can be stopped, so as to ensure the audio quality of the audio signal as much as possible.
Illustratively, when the second threshold is 6db, in the case that the difference R1-R2 between the actual reception level R1 and the theoretical reception level R2 is <6db, the continuous reduction of the sampling size and the sampling frequency of the audio signal may be stopped to ensure the audio quality of the audio signal as much as possible.
It should be noted that, in the embodiment of the present application, in the case that the audio type is the first audio type, in the case that the theoretical reception level R2 is greater than or equal to the first threshold, or in the case that the difference between the actual reception level R1 and the theoretical reception level R2 is less than or equal to the second threshold, the interference of the audio signal on the radio frequency signal is negligible. At this time, the audio signal does not need to be processed, so that the audio signal can maintain high-quality output, and the use experience of a user is improved.
Substep S24: and under the condition that the audio type is a second audio type, performing interference reduction processing on the audio signal.
In the embodiment of the present application, in the case that the audio type is the second audio type, it may be considered that the user may watch short videos or make calls using the digital headset, and the requirement on the audio quality is low. In this case, the audio signal may be directly subjected to interference reduction processing to reduce interference of the audio signal with the radio frequency signal, and reduce an influence of the audio signal on communication quality of the lower antenna, so that cellular communication quality of the electronic device may be improved.
Specifically, the interference reduction processing performed on the audio signal in this step may specifically refer to the interference reduction processing in sub-step S23, which is not described herein again.
In summary, the control method according to the embodiment of the present application may include at least the following advantages:
in the embodiment of the present application, the transmission quality requirement of the audio signal and the influence of the audio signal on the cellular communication quality may be determined according to the sampling parameter. From the theoretical receive level and the actual receive level, the type of the radio frequency signal and whether the radio frequency signal is interfered may be determined. According to the transmission quality requirement of the audio signal, the influence of the audio signal on the cellular communication quality, the type of the radio frequency signal and the condition whether the radio frequency signal is interfered, the audio signal is processed, the influence of the audio signal on the communication quality of the lower antenna can be reduced on the premise of meeting the transmission quality of the audio signal, and therefore the cellular communication quality of the electronic equipment is improved.
