The electronic device may select different communication channels according to different cells, and frequency channels of the different communication channels may overlap frequencies of the speaker, so that the frequencies of the speaker interfere with the frequency channels of the communication channels, thereby affecting quality of the communication channels and user experience.
Referring to fig. 2, fig. 2 is a method for preventing speaker interference in communication according to the present disclosure, where the method is executed by an electronic device, and the electronic device may specifically include: one of a smart phone, a tablet computer, a palm computer, a notebook computer, a mobile internet device or a wearable device, where the method is shown in fig. 2 and includes the following steps:
step S201, the electronic device determines a first mode of power amplifier work of a loudspeaker, and N channels (N is an integer larger than or equal to 1) interfered by the first mode are obtained according to the first mode;
the first working frequency point of the speaker is determined according to the first mode, and a calculation mode or a test mode may be adopted according to the mode of the N channels with which the first working frequency point interferes, which is obtained by calculation of the first working frequency point.
Step S202, when the electronic device starts the communication module, the electronic device receives a first traffic channel designated by the network side equipment.
The specific method for the electronic device to receive the first traffic channel specified by the network-side device in step S202 may be that, for the calling process, a corresponding flowchart is shown in fig. 2a, as shown in fig. 2a, the method includes the following steps:
step S201a, the electronic device sends a channel requirement to the base station, and the specific implementation manner may be that the electronic device sends a short random access burst to the base station.
Step S202a, the base station assigns an Independent dedicated channel (SDCCH) to the electronic device on a Broadcast Channel (BCH).
Step S203a, the electronic device communicates with the base station on SDCCH.
Step S204a, the electronic device performs authority authentication with the base station.
Step S205a, after the authority authentication is successful, the base station sends a designated traffic channel (TCH for short) to the mobile phone.
Step S206a, the electronic device performs voice data transmission with the base station through the TCH.
For the called flow, the flow is shown in FIG. 2b,
step S201b, the base station uses IMSI number in SIM to call the called terminal on the calling channel of paging channel (PCH for short);
step S202b, the called terminal sends an Access request to the base station in a Random Access Channel (RACH);
step S203b, the base station appoints BCH to the called terminal;
step S204b, the called terminal communicates with the base station on SDCCH.
Step S205b, the called terminal performs authority authentication with the base station.
Step S206b, after the authority authentication is successful, the base station sends a designated service signal to the called terminal.
Step S207b, the called terminal performs voice data transmission with the base station through the TCH.
Step S203, the electronic device determines whether the first traffic channel belongs to the N channels, and if the first traffic channel belongs to the N channels, the electronic device changes the power amplifier operating mode of the speaker from the first mode to the second mode.
The second mode may specifically be a working mode different from the first mode, and specifically, an absolute value of a difference between a second working frequency point and a first working frequency point of the speaker in the second mode is greater than a frequency threshold. The setting can ensure that the channels interfered by the second mode are not N channels, so that the mode of the power amplifier of the loudspeaker is adjusted from the first mode to the second mode to have certain significance.
According to the technical scheme, whether a first service channel belongs to N channels or not is determined according to a first mode of working of the loudspeaker, if the first service channel belongs to the N channels, the working mode of the loudspeaker power amplifier is changed from the first mode to a second mode by the electronic device, so that the working mode of the loudspeaker power amplifier is in the second mode, interference on the N channels is avoided, the communication quality of the electronic device is improved, the communication quality is improved, and the user experience is improved.
Optionally, after step S203, the method may further include:
and the electronic device receives a second service channel appointed by the network side equipment, and if the second service channel does not belong to the N channels, the electronic device adjusts the working mode of the power amplifier of the loudspeaker back to the first mode.
For electronic equipment, the optimal operating mode of the speaker power amplifier may also be referred to as a default operating mode as a first mode, where the operating efficiency of the power amplifier is highest and the effect of the speaker is best in the first mode, but the optimal operating mode may interfere with a part of communication channels in a GSM communication channel (e.g., a traffic channel), and at this time, if the GSM communication channel belongs to the part of communication channels, the operating mode of the speaker power amplifier needs to be adjusted from the default mode to a second mode, so that although a part of the audio effect is sacrificed, the interference with N channels is avoided, and the quality of the channels is improved.
Optionally, the method may further include:
and the electronic device receives a third service channel appointed by the network side equipment again, if the third service channel belongs to the N channels, whether the electronic device is connected with the earphone is detected, if the electronic device is connected with the earphone, the conversation of the electronic device is switched to the earphone for answering, and the power amplifier of the loudspeaker is closed.
When the current service channel is switched to the N channels again, the communication of the electronic device is switched to the earphone to answer by detecting whether the earphone is connected or not of the electronic device, for example, the earphone is connected (the connection can comprise wired connection or wireless connection), the power amplifier of the loudspeaker is closed, the frequency of the power amplifier of the loudspeaker is zero, and the power amplifier of the loudspeaker cannot generate any interference on the communication channel, so that the communication channel has the advantages of avoiding interference and improving the communication quality.
Optionally, the method may further include:
the electronic device detects the MIPI frequency of the display equipment, determines whether the MIPI frequency is interfered with a first working frequency point corresponding to the first mode, and if the MIPI frequency is determined to be interfered with the first working frequency point corresponding to the first mode, the electronic device starts the MIPI spread spectrum of the display equipment.
For the MIPI frequency of the display device, if the MIPI frequency is close to the first working frequency point corresponding to the first mode of the speaker, the MIPI frequency of the display device interferes with the frequency of the speaker, the frequency of the speaker also interferes with the display device, at this time, the MIPI spread spectrum is started, although the frequency of the speaker also interferes, the interference of the MIPI spread spectrum is much smaller than the interference of normal display of the display device, so the MIPI spread spectrum of the display device is started at this time, after the MIPI spread spectrum is started by the display device, the frequency range of the interference of the display device is increased, but the interference strength is reduced, although the interference of the MIPI frequency with the speaker cannot be completely avoided, the interference of the MIPI frequency with the speaker can be reduced, so that the communication quality is improved, and the user experience is improved.
Referring to fig. 3a, fig. 3a is a schematic diagram of data transmission of a display device (e.g., a liquid crystal panel), as shown in fig. 3a, the digital signals output by the LCD driving board include RGB data signals, i.e., RGB colors representing three channels of Red, Green, and Blue, which are commonly known as three primary colors, wherein R represents Red (Red), G represents Green (Green), and B represents Blue (Blue); and also includes signals such as line synchronization (Hsync, Vertical synchronization), field synchronization (Vsync, Vertical synchronization), Data Enable (DE, Data Enable), and pixel clock. Taking the output of a low-voltage differential signaling (LVDS) interface as an example, the arrangement of the signals is shown in fig. 3 a. Two transmission modes are defined in the LVDS transmission protocol: a Data Enable mode (DE mode, full name of Data Enable mode) and a synchronization mode (Sync mode, full name of synchronization mode); DE mode only needs the DE signal to synchronize RGB data, Sync mode needs to synchronize RGB data with Hsync and Vsync.
Referring to fig. 3b, a schematic diagram of a relationship between an LCD display timing and an operating timing of a speaker is shown, as shown in fig. 3b, input DE may be an input enable signal, input RGB data may be input RGB data for a line buffer in a TCON IC, output RGB data may be output RGB data for a line buffer in a TCON IC, and STV is a start signal generated or generated in a TCON IC, where the STV is used for processing input RGB data only by data in a clock control chip (TCON IC) after an STV timing, and since an electronic device normally operates, a corresponding display is normally displayed, as shown in fig. 3b, that is, in an interval shown by tx, if the timing of the speaker is also at a high level, the input RGB data and the output RGB data interfere with the speaker. Therefore, according to the technical scheme provided by the application, the MIPI frequency of the display device is detected, whether the MIPI frequency is interfered with the first working frequency point corresponding to the first mode or not is determined, the electronic device determines the first time t1 when the loudspeaker is turned on and the second time t2 when the loudspeaker is turned off, and the electronic device keeps the start signal STV of the clock control chip of the display device at a low level (namely, the level signal is 0) in the interval between t1 and t 2. The specific timing diagram is shown in fig. 3 c.
In this way, by controlling the level of the STV, the on-time and the off-time can be recorded when the speaker is turned on, and the transmission of output RGB data of the display device is cut off between the on-time and the off-time, and the frequency of the STV at this time is also zero, so that the interference to the speaker due to the display of the display device is not affected, and the interference to the communication channel is not affected to the MIPI frequency of the display device.
As shown in fig. 3c, the input DE may be an input enable signal, the input RGB data may be input RGB data for a line buffer in the TCON IC, the output RGB data may be output RGB data for a line buffer in the TCON IC, and the STV is a start signal generated or generated in the TCON IC, and the STV is used for processing the input RGB data only in the clock control chip (TCON IC) after the STV timing sequence, and since the electronic device normally operates, the corresponding display is normally displayed, as shown in fig. 3c, that is, in the interval shown in [ t1, t2 ], if the speaker also operates, and the STV also has a certain frequency, the input RGB data, the output RGB data, and the STV interfere with the speaker. Therefore, according to the technical scheme provided by the application, the first time t1 when the loudspeaker is turned on and the second time t2 when the loudspeaker is turned off are determined, and the electronic device keeps the starting signal STV of the clock control chip of the display device at a low level (namely, the level signal is 0) in the interval between t1 and t 2. Since the speaker is operated without a display device, the STV is set to a low level, which does not affect the user experience, since the user does not need to view the content of the display screen.
