The control method provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of steps of a control method according to an embodiment of the present application is shown, where the control method may be applied to an electronic device, where the electronic device may establish a communication connection with a digital earphone. As shown in fig. 1, the method specifically may include:
step 101: and under the condition that the electronic equipment and the digital earphone are in communication connection, acquiring sampling parameters of the transmitted audio signals.
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 earphone is an earphone product which is directly connected with the electronic equipment in a communication way by using a digital interface. The digital headphones may include, but are not limited to, a pocket earplug and a design of the headphone.
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 (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 this embodiment of the present application, when the electronic device and the digital earphone establish a communication connection, sampling parameters of an audio signal transmitted by the digital earphone may be obtained.
Referring to fig. 2, a schematic hardware structure of an electronic device and a digital earphone according to an embodiment of the present application is shown, and 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 further include a headset 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 headset 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 earphone 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 earphone 200 can be established.
In a specific application, where the electronic device 100 establishes a communication connection with the digital earphone 200, the first audio codec chip 102 on the electronic device 100 may be used to collect sampling parameters of an audio signal transmitted by the digital earphone 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. The larger the sampling parameter is, the larger the audio data to be transmitted between the electronic device and the digital earphone is, the higher the data transmission rate between the electronic device and the digital earphone 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 a high definition movie using the digital earphone, 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 parameters of the audio signal are correspondingly lower due to the lower quality of the audio signal.
Step 102: a theoretical reception level and an actual reception level of the radio frequency signal are obtained.
In this embodiment of the present application, the processor 101 in the electronic device may be further configured to obtain a theoretical reception level and an actual reception level of the radio frequency signal when the electronic device establishes a communication connection with the digital earphone.
Specifically, the radio frequency signal may be received by an antenna of the electronic device, demodulated by a modem after low noise amplification, and then identified by a processor of the electronic device after digital-to-analog conversion to receive an actual reception level R1 of the radio frequency signal. The theoretical reception level of the rf signal may be calculated according to the processor 101 of the electronic device.
In an alternative embodiment of the present application, the method for obtaining the theoretical reception level of the radio frequency signal may specifically comprise the following sub-steps:
sub-step S11: a first transmit level, a second transmit level of a base station, and a first receive level of an electronic device are acquired.
In this embodiment of the present application, in a case where a user uses the cellular network of the electronic device and the digital earphone at the same time, the electronic device may obtain, through communication with a base station, a respective transmission level and a reception level, so as to calculate, based on the respective transmission level and the reception level, a theoretical reception level of the radio frequency signal under a condition of no interference.
Specifically, based on the communication connection between the electronic device and the base station, the processor 101 of the electronic device may obtain a first transmission level P1 of the electronic device, and a second transmission level P2 and a 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 this 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 according to the first transmission level P2 and the first reception level R3.
Specifically, the uplink path loss L2 and the downlink path loss L1 of the radio frequency signal may be calculated according to the following formulas:
l2=p1-R3 (formula 1)
L1=p2—r2 (formula 2)
Wherein R2 is a theoretical reception 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 in the default absence of frequency selective fading, i.e
L2.apprxeq.L1 (equation 3)
From equations 1, 2 and 3, a calculation equation of the theoretical reception level R2 of the radio frequency signal can be determined:
r2=p2-p1+r3 (formula 4)
In this embodiment of the present 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 may be determined according to the theoretical reception level R2. Moreover, the processor 101 of the electronic device may compare the actual reception level R1 with the theoretical reception level R2, and determine whether the digital earphone has interference on the transmission of the radio frequency signal of the electronic device according to 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 this embodiment of the present application, the transmission quality requirement of the audio signal may be determined according to the sampling parameter, and the 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 is possible to determine the type of the radio frequency signal and whether the radio frequency signal is interfered. 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 whether the radio frequency signal is interfered or not, the audio signal is processed, and the influence of the audio signal on the communication quality of a lower antenna can be reduced on the premise of meeting the transmission quality of the audio signal, so that the cellular communication quality of the electronic equipment is improved.
In summary, the control method according to the embodiments of the present application may at least include the following advantages:
in this embodiment of the present application, when the electronic device and the digital earphone establish a communication connection, sampling parameters of a transmitted audio signal may be obtained; 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 to 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.
Referring to fig. 3, a flowchart illustrating steps of another control method according to an embodiment of the present application, as shown in fig. 3, the control method may specifically include the following data:
step 301: and under the condition that the electronic equipment and the digital earphone are in communication connection, acquiring sampling parameters of the transmitted audio signals.
In this embodiment, the specific implementation process of step 301 may refer to step 101 in the foregoing embodiment, which is not described herein.
Step 302: a theoretical reception level and an actual reception level of the radio frequency signal are obtained.
In this embodiment, the specific implementation process of step 302 may refer to step 102 in the foregoing embodiment, which is not described herein.
Step 303: and determining the audio type of the audio signal according to the sampling parameters.
In the embodiment of the 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 thus, from the sampling parameters, the audio type of the audio signal can be determined.
In particular, the audio types may include a first audio type, which may be an audio type with a higher audio quality, and a second audio type, which may be in particular an audio type with a 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, at which time the type of the audio model may be determined to be the first audio type according to the sampling parameters. In a scenario where the user uses the digital earphone to watch a short video or make a call, the audio type may be determined to be the second audio type at this time because the quality of the audio signal is low and the sampling parameter of the audio signal is correspondingly low.
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 application, according to the audio type, the transmission quality requirement of the audio signal and the influence of the audio signal on the cellular communication quality can be determined. From the theoretical reception level R2 and the actual reception level R1, it is possible to determine the type of the radio frequency signal and whether the radio frequency signal is disturbed. 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 whether the radio frequency signal is interfered or not, the audio signal is processed, and the influence of the audio signal on the communication quality of a lower antenna can be reduced on the premise of meeting the transmission quality of the audio signal, so that 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:
in step S21: and determining the interference condition of the transmission of the audio signal on 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 this embodiment of the present application, in the case where 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 also faster, and the influence on the quality of cellular communication of the electronic device is also greater. In this case, the interference situation of the transmission of the audio signal on 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 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 smaller than the first threshold, the radio frequency signal can be regarded as a weak signal, and the communication quality is generally poor when cellular communication is performed using the weak signal. In the case where the theoretical reception level R2 is greater than or equal to the first threshold, the radio frequency signal can be regarded as a strong signal, and the communication quality is generally good when cellular communication is performed using the strong signal.
Specifically, the first threshold may be used as a threshold for determining the strength of the radio frequency signal, and a specific value thereof may be set according to an actual situation. For example, the first threshold may be-80 dbm, the radio frequency signal may be considered a weak signal in case of a theoretical reception level R2< -80dbm, and the radio frequency signal may be considered a strong signal in case of a theoretical reception level R2> -80dbm or r2= -80 dbm.
In a specific application, in the case that the radio frequency signal is a strong signal, the interference of the audio signal to the radio frequency signal is negligible due to the better communication quality of the radio frequency signal. In the case that the radio frequency signal is a weak signal, because the communication quality of the radio frequency signal is poor, the interference of the audio signal on the radio frequency signal has a great influence on the communication quality.
In this embodiment of the present application, due to interference of the audio signal of the digital earphone on the radio frequency signal, the actual receiving level R1 and the theoretical receiving level R2 of the radio frequency signal by 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 is possible to determine 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 may be considered that the audio signal has a greater interference to the current frequency band of the radio frequency signal. In the case that the difference between the actual receiving level R1 and the theoretical receiving level R2 is smaller than or equal to the second threshold, the interference of the audio signal on the current frequency band of the radio frequency signal may be considered to be smaller and may be ignored.
Specifically, the second threshold may be used as a threshold for determining the magnitude of the influence of the audio signal on the communication quality of the radio frequency signal, and a specific value thereof may be set according to actual situations. For example, the second threshold may be 6db. Thus, the difference R1-R2 between the actual reception level R1 and the theoretical reception level R2 is >6db, and it is considered that the audio signal has a large interference with the current frequency band of the radio frequency signal.
In case the difference R1-R2 between the actual reception level R1 and the theoretical reception level R2 is <6db or r1-r2=6db, the audio signal may be considered to have a small interference with the current frequency band of the radio frequency signal, which may be negligible.
In this 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 better, and in this case, the interference of the audio signal on the radio frequency signal may be negligible. In the case that the difference between the actual receiving level R1 and the theoretical receiving level R2 is smaller than or equal to the second threshold, the interference of the audio signal on the current frequency band of the radio frequency signal may be considered to be smaller and may be ignored. Therefore, only if the theoretical reception level is smaller than the first threshold value and the difference between the actual reception level and the theoretical reception level is larger than the second threshold value, it can be determined that the audio signal has interference on the radio frequency signal, and the audio signal transmitted by the digital earphone has a larger influence on the communication quality of the radio frequency signal.
Substep S23: performing interference reduction processing on the audio signal in a case where transmission of the audio signal interferes with transmission of the radio frequency signal.
In this embodiment of the present invention, when there is interference in the transmission of the audio signal of the digital earphone to the transmission of the radio frequency signal, the interference reduction processing may 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 device.
Specifically, the interference reduction processing may specifically include: reducing sampling parameters of the audio signal. I.e. reducing the sampling size and the sampling frequency of the audio signal. In this way, the transmission rate of the audio signal can be reduced, and further, the interference of the audio signal on the radio frequency signal can be reduced.
In practical applications, after the sampling size and the sampling frequency of the audio signal are reduced, the interference of the audio signal on the radio frequency signal is also reduced in a reply manner, and correspondingly, the difference between the actual receiving level R1 and the theoretical receiving level R2 of the radio frequency signal is also reduced correspondingly. In order to ensure 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 smaller 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, so that the continuous reduction of the sampling size and the sampling frequency of the audio signal can be stopped to ensure the audio quality of the audio signal as much as possible.
For example, when the second threshold is 6db, in the case that the difference R1-R2 between the actual receiving level R1 and the theoretical receiving level R2 is less than 6db, the continuous reduction of the sampling size and the sampling frequency of the audio signal may be stopped, so as 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 where the audio type is the first audio type, in the case where the theoretical reception level R2 is greater than or equal to the first threshold value, or in the case where the difference between the actual reception level R1 and the theoretical reception level R2 is less than or equal to the second threshold value, the interference of the audio signal on the radio frequency signal may be negligible. At this time, any processing on the audio signal is not required, so that the audio signal can maintain higher-quality output, and the use experience of a user is improved.
Substep S24: and carrying out interference reduction processing on the audio signal under the condition that the audio type is the second audio type.
In this embodiment of the present application, in the case where the audio type is the second audio type, it may be considered that the user may use the digital earphone to watch a short video or make a call, which has a low requirement on audio quality. In this case, the interference reduction processing may be directly performed on the audio signal, so as to reduce interference of the audio signal on 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 the substep S23, which is not described herein.
In summary, the control method according to the embodiments of the present application may at least include the following advantages:
in this embodiment of the present application, the transmission quality requirement of the audio signal may be determined according to the sampling parameter, and the influence of the audio signal on the cellular communication quality may be determined. Based on the theoretical and actual reception levels, a type of the radio frequency signal and whether the radio frequency signal is subject to interference 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 whether the radio frequency signal is interfered or not, the audio signal is processed, and the influence of the audio signal on the communication quality of a lower antenna can be reduced on the premise of meeting the transmission quality of the audio signal, so that the cellular communication quality of the electronic equipment is improved.
