[0057] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0058] Electronic devices (such as laptops) may experience blue screen errors for unknown reasons. These errors can be caused by: software incompatibility issues, hardware driver incompatibility issues, poor contact or damage to the memory modules, etc. A blue screen may also produce noise, affecting the user experience.

[0059] For example, please refer to Figure 1, which is an example diagram of the playback path of noise after a blue screen in an electronic device. As shown in Figure 1, after a blue screen occurs in an electronic device due to the above reasons, the System on Chip (SOC) may emit noise (for example, some components in the SOC emit noise due to malfunction, or the cooling fan emits noise due to a system crash in the SOC). For ease of description, the noise generated by the SOC is referred to as noise 1. Noise 1 can be encoded and decoded by a codec to generate noise 2. Noise 2 is then amplified to a sufficiently high level by a power amplifier (PA) to generate noise 3. Noise 3 is then played to the outside world through a speaker.

[0060] A blue screen is a forced display of an image on an electronic device to protect its data files from corruption when the operating system is unable to recover from a system error. A blue screen can indicate that the operating system has crashed or that a hardware malfunction has occurred.

[0061] To address the issue of noise that may occur after an electronic device experiences a blue screen, this application proposes a control method for such devices. After a blue screen occurs, a callback mechanism enables the hardware layer to receive the blue screen message, and then the state of the hardware (such as a codec, power amplifier, speaker, etc.) is controlled based on this message. For example, controlling the entire codec component shown in Figure 1 to be in a non-operating state prevents noise processing and prevents it from being played to the outside, effectively cutting off the noise transmission path from the inside of the electronic device to the outside, thus achieving a silent effect. Alternatively, controlling the mute pin in the codec shown in Figure 1 to be in an active state ensures that noise is muted during processing by the codec, achieving a silent effect for the electronic device.

[0062] The control method of the electronic device provided in the embodiments of the present application is applied to an electronic device that can have a blue screen phenomenon. The electronic device can also be referred to as a terminal, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), and the like. The electronic device can be a mobile phone, a smart television, a tablet computer (Pad), a notebook computer, a desktop computer, a computer with wireless transceiver function, a virtual reality (VR) electronic device, an augmented reality (AR) electronic device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, and the like.

Among them, the machine instruction refers to the instruction that can be directly recognized and executed by the CPU, and the generalized instruction refers to the software instruction defined and interpreted by the system. Exemplarily, the operating system layer includes a content management module, a process management module, a file management module, a device management module, a driver management module, and the like.

[0095] The memory management module is mainly used for the management of memory, and the main tasks are to allocate memory space, ensure that the storage space occupied by each job does not conflict, and make each job in its own storage area not interfere with each other.

[0096] The essence of the process management module is to manage the central processing unit, so the process management module is often also called the processor management module. The process management module can be used for the management of process control, process synchronization, inter-process communication and process scheduling. Among them, process control mainly handles the creation state conversion of the process, process revocation, and allocation and recovery of related process resources; process synchronization mainly handles the relationship between inheritance, including process synchronization and mutual exclusion, inter-process communication mainly handles the exchange of information between mutually cooperative processes, and process scheduling is to select a process from the ready queue according to a certain algorithm and really execute it in the processor.

[0097] The file management module is used to manage various hardware resources, such as U disk, network disk, keyboard, etc.

[0098] The device management module is mainly used to manage various peripheral devices (referred to as peripherals), including allocation, start and fault handling, etc., and the main tasks are: when the user uses external devices, the user must make a request, and after the operating system is allocated uniformly, the user can use it. When the user's program runs to use a certain peripheral, the operating system is responsible for driving the peripheral.

[0099] The driver management module is used to provide the connection between programs and hardware, and provide various system services and interfaces.

[0100] The driving layer is a layer between hardware and software, and various driving modules are included in the driving layer. The driving modules can drive the programs of the software in the computer. The driving program, full name device driving program, is a special program added to the operating system, which contains information about the hardware device. This information enables the computer to communicate with the corresponding device. For example, the driving layer can include driving module A and driving module B. Driving module A can communicate and coordinate with processor A in the hardware layer, so that the operating system layer can correctly interact with processor A. It should be understood that driving module A can also include an audio driving module, a graphics card driving module, an on-screen display (OSD) driving module, and the like, which are not limited in the embodiments of the present application. Driving module B can communicate and coordinate with processor B in the hardware layer, so that the operating system layer can correctly interact with processor B. It should be understood that driving module A and driving module B are illustrated as separate modules in the embodiments of the present application, and in other embodiments, the above driving modules can be combined, or a single driving module can be integrated into another driving module, which is not limited in the embodiments of the present application.

[0101] The hardware layer, as the lowest module in the device, can include processor A, processor B, codec, speaker, power amplifier, and the like shown in FIG. 3.

[0102] It should be understood that the software and hardware architecture diagram shown in FIG. 3 is only illustrative and should not be limited to the embodiments of the present application.

[0103] The above embodiments introduce the hardware structure and software architecture of the electronic device 100, and the following embodiments introduce the application scenarios of the control method of the electronic device provided in the embodiments of the present application.

[0104] Please refer to FIG. 4, which is an example diagram provided to compare the related scheme with the scheme provided in the embodiments of the present application.

[0105] As shown in (a) of FIG. 4, when the electronic device (such as a notebook computer) appears a blue screen phenomenon, the display screen of the electronic device will display a blue interface 401, and the blue interface displays the words 402 such as “Your computer has encountered a problem, we collect some error information, and then you can restart”, and the speaker will emit “tata” or “zizi” noise.

[0106] After the control method of the electronic device provided in the embodiments of the present application is applied to the electronic device, as shown in (b) of FIG. 4, when the electronic device displays the blue interface 403, the display screen of the electronic device will still display the words 404 such as "Your PC ran into problems and needs to restart. Please save your work first, and don't turn off your computer", but the probability of the speaker emitting noises such as "tata" or "zizi" will be reduced, and in some embodiments, the speaker of the electronic device will not emit noises, thus improving the user experience.

[0107] The above embodiments introduce the application scenarios of the control method of the electronic device provided in the embodiments of the present application. The following embodiments introduce the implementation process of the control method of the electronic device provided in the embodiments of the present application.

[0108] Please refer to FIG. 5, which is an example diagram of a control method of an electronic device provided in the embodiments of the present application. The numbers in the circles shown in FIG. 5 represent steps, for example, the control method shown in FIG. 5 includes steps 501 to 504.

[0109] In step 501, the processor B is connected with the component 1 in the Codec, or the processor B is connected with the component 2 in the PA.

[0110] It should be understood that the role of the processor B is that the processor B can work throughout the life of the electronic device 100, that is, even if the electronic device is powered off, or the software of the processor A in the electronic device crashes or the hardware fails, causing the electronic device to appear a blue screen phenomenon, the processor B can still work. The processor B can be an EC, and the type of the processor B is not limited in the embodiments of the present application.

[0111] It should also be understood that after the electronic device appears a blue screen phenomenon, that is, the software of the processor A in the electronic device crashes or the hardware fails, the processor A cannot control the state of the components on the noise playing path of the electronic device after the electronic device appears a blue screen, causing the electronic device A to emit noises. In the embodiments of the present application, in the case that the software of the processor A crashes or the hardware fails, the electronic device can control the state of the components on the noise playing path of the electronic device after the electronic device appears a blue screen based on the role of the processor B, so as to cut off the noise playing path or make the noises be muted.

[0112] For example, please refer to FIG. 6, which is an example diagram of a hardware structure of a processor B provided in the embodiments of the present application.

[0113] The processor B can include two buses, an internal bus and an EC dedicated bus. The internal bus is used for the processor A to access the logic devices (power management channel (PMC), keyboard controller (KBC)) hung below the internal bus, and can also be used for communication between the logic devices. The EC dedicated bus is used for communication between the functional modules hung below the EC dedicated bus, and communication between the functional modules hung below the EC dedicated bus and the logic devices hung below the internal bus. The functional modules hung below the EC dedicated bus can include an analog-to-digital converter (ADC) and general-purpose input / output ports (GPIO) 601.

[0114] The processor B can also include a single-chip microcomputer. The processor B can realize keyboard control, touchpad control, power management, fan control, battery management, and the like through the single-chip microcomputer.

[0115] The hardware structure of the processor B is introduced as above. It can be understood that the components included in the hardware structure shown in FIG. 6 do not constitute a specific limitation on the processor B. The processor B can have more or fewer components than those shown in the figure, can combine two or more components, or can have a different component configuration. The various components shown in FIG. 6 can be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and / or application-specific integrated circuits.

[0116] In the embodiment of the present application, the GPIO 601 in the processor B shown in FIG. 6 can be connected to the component 1 in the Codec, or the GPIO 601 in the processor B can be connected to the component 2 in the PA. The above hardware connection is used for the processor B to control the component 1 in the Codec or the component 2 in the PA. For example, the processor B controls the component 1 in the Codec to switch from high level to low level, or controls the component 2 in the PA to switch from high level to low level, so as to mute the electronic device or cut off the noise playing path.

[0117] The following embodiment introduces the component 1 in the Codec.

[0118] For example, refer to FIG. 7, which is a hardware structure example diagram of a Codec provided by an embodiment of the present application.

[0119] As shown in FIG. 7, the Codec includes a digital audio interface (DAI) for inputting a digital signal of a specific sampling frequency to a Codec input processor A.

[0120] Digital filters (DF) are used to convert the digital signal of the specific sampling frequency into a multi-bit oversampled digital signal.

[0121] A digital to analog converter (DAC) is used to convert the digital signal into an analog signal.

[0122] A mute pin A (MUTE) 701 is used to set mute, cutting off the output of the digital to analog converter.

[0123] A side tone pin (SIDTONE) is used to select whether to mix the analog signals of the sound signal collected through a microphone (MIC) and the audio signal collected through other audio devices (LINEIN).

[0124] Left and right channel output pins 702 of a speaker are used to connect the left and right channels of the speaker.

[0125] A volume pin is used to set the volume, and a mute pin B (MUTE) 703 is used to set mute.

[0126] A driver pin (DRIVER) is used to maintain the driving current of the earphone, avoiding noise when mute or standby.

[0127] Left and right channel output pins 704 of an earphone are used to connect the left and right channels of the earphone.

[0128] It should be noted that in some embodiments, the above-mentioned name "pin" can also be referred to as "leg", etc., and the embodiments of the present application do not limit this.

[0129] As for the hardware structure of the Codec, it is understood that the components included in the hardware structure shown in FIG. 7 do not constitute a specific limitation on the Codec. The Codec can have more or fewer components than those shown in the figure, can combine two or more components, or can have a different component configuration. The various components shown in FIG. 7 can be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and / or application specific integrated circuits.

[0130] It should be understood that the noise generated by the processor A can be played to the outside world through the components shown in FIG. 7. The noise generated by the processor A can be played to the outside world through the speaker after being processed by the Codec, or can be played to the outside world through the earphone after being processed by the Codec. The following describes an audio playing path A in which the noise is played to the outside world through the speaker, and an audio playing path B in which the noise is played to the outside world through the earphone.

[0131] The audio playing path A:

[0132] As shown in FIG. 7, the noise can be processed by the digital audio interface, the digital filter, the analog-digital converter, the mute pin A 701, the side tone pin, and the left and right channel output pins 702 of the speaker in sequence, and then played to the outside world through the speaker.

[0133] The audio playing path B:

[0134] As shown in FIG. 7, the noise can be processed by the digital audio interface, the digital filter, the analog-digital converter, the mute pin A 701, the side tone pin, the volume pin, the mute pin B 703, the driving pin, and the left and right channel output pins 704 of the earphone in sequence, and then played to the outside world through the speaker.

[0135] In the embodiment of the present application, the component 1 can be the mute pin A 701 shown in FIG. 7, or the left and right channel output pins 702 of the speaker, or the mute pin B 703, or the left and right channel output pins 704 of the earphone, etc. Of course, in other embodiments, the component 2 can also be other components in the Codec, which is not limited in the embodiment of the present application.

[0136] In the implementation, the electronic device can connect the GPIO in the processor B shown in FIG. 6 with the mute pin A 701, or the left and right channel output pins 702, or the mute pin B 703, or the left and right channel output pins 704 of the earphone in the Codec shown in FIG. 7.

[0137] The following embodiment describes the component 2 in the PA.

[0138] For example, please refer to FIG. 8, which is an example diagram of the hardware structure of a PA provided in the embodiment of the present application.

[0139] As shown in FIG. 8, the power amplifier (PA) at least includes the following pins: a mute pin C 801, a power supply pin 802, an output pin 803, and the like. Among them, the PA is used to amplify the power of the input signal to a level suitable for the load. The mute pin C is used to set the mute. The power supply pin is used to connect the power supply module in the electronic device with the PA. The output pin is used to output the audio signal. Of course, the PA can also include other pins, such as the power supply H-bridge of the left channel and the power supply H-bridge of the right channel shown in FIG. 8, the power limit pin (LIMIT), and the like. The power supply H-bridge of the left channel and the power supply H-bridge of the right channel are used for internal connection of the left channel and the right channel power supply input. LIMIT is used to limit or adjust the power of the PA.

[0140] Among them, the output pin 803 can be an H-bridge right channel output pin, a left channel output pin, and the like.

[0141] As for the hardware structure of the PA, it can be understood that the components included in the hardware structure shown in FIG. 8 do not constitute a specific limitation on the PA. The PA can have more or fewer components than those shown in the figure, can combine two or more components, or can have a different component configuration. The various components shown in FIG. 8 can be implemented in hardware, software, or a combination of hardware and software including one or more signal processing and / or application specific integrated circuits.

[0142] In the embodiment of the application, the component 2 can be the mute pin C 801 shown in FIG. 8, or the power supply pin 802, or the output pin 803. Of course, in other embodiments, the component 2 can also be other components in the power amplifier, which is not limited in the embodiment of the application.

[0143] In the implementation, the electronic device can connect the GPIO in the processor B shown in FIG. 6 with the mute pin C 801, or the power supply pin 802, or the output pin 803, and the like in the PA shown in FIG. 8.

[0144] It should be understood that the mute pin in the above embodiment can be a hard mute pin or a soft mute pin, which is not limited in the embodiment of the application.

[0145] In other embodiments, in addition to connecting the processor B with the component 1 in the Codec in step 501, or connecting the processor B with the component 2 in the PA, the processor B can also be connected with other components on the playing path of the noise from the inside of the electronic device to the outside, such as the mute pin, the power supply pin, the output pin, the input pin, and the like in the speaker, which is not limited in the embodiment of the application.

[0146] At step 502, the electronic device registers the callback function in the processor A, and in the case that the electronic device appears the blue screen phenomenon, the processor A acquires the blue screen message through the callback function.

[0147] It should be understood that the callback function is an application of the function pointer, in common parlance, the callback function is to call a function by using the function pointer, and the callback function registration is a process of passing the function pointer as a parameter to facilitate the use of other modules.

[0148] It should also be understood that the blue screen event is an event that causes the electronic device to appear the blue screen phenomenon, such as system crash of the processor A, hardware failure, etc. The blue screen message can refer to the dump file collected by the processor A after the blue screen event occurs. The dump file refers to the dynamic (or volatile) data dumped into a static (such as a file) form after the blue screen event occurs.

[0149] For example, the callback function can be the KeRegisterBugCheckReasonCallback() function, and the embodiments of the present application do not limit the type of function. The callback function can include input, output parameters, etc., and the embodiments of the present application do not limit this.

[0150] It can also be understood that in order to read the blue screen message after the electronic device appears the blue screen phenomenon due to system crash of the processor A, hardware failure, etc., the processor A can register a callback function in the processor A, and the electronic device can fill the blue screen message into the callback function in real time when the blue screen event occurs, and the processor A can acquire the blue screen message through the callback function.

[0151] At step 503, the processor A sends the blue screen message to the processor B.

[0152] It should be understood that the processor A can send the blue screen message to the processor B through the power management channel (PMC).

[0153] It should also be understood that the PMC can be used as a communication channel between the host processor (such as the processor A) and the embedded controller (such as the processor B). The PMC can provide four registers, namely the power management data register (PMDIR), the power management data output register (PMDAT), the power management data input register (PMDIN) and the power management data control register (PMDCR).

[0154] (Power Management Data Output Register, PMDOR), a Power Management Channel Memory Data Register (PMCMDR), and a Power Management State Register (PMSTR). These four registers are used for communication between the host processor (e.g., processor A) and the embedded controller (e.g., processor B). The PMDIR register can be written by the host processor and read by the embedded controller. The PMDOR register can be written by the embedded controller and read by the host processor. Both the host processor and the embedded controller can read the PMCMDR or the PMSTR register.

[0155] It is also understood that the embedded controller (e.g., processor B) also includes three registers, namely, an EC State Register, an EC Command Register, and an EC Data Register. The EC State Register is used for reading data, the EC Command Register is used for writing data, and the EC Data Register is used for transferring data between processor A and processor B.

[0156] In implementation, processor A sends read and write commands to processor B through the PMC to transfer data. For example, processor A can send a read EC register command (e.g., the command can be 0x80) to processor B through the PMC, where the address offset of an EC Random Access Memory (RAM) resource is immediately after 0x80. Processor A can read the content in the EC Data Register when an Output Buffer Full (OBF) signal of the EC State Register is set. The OBF signal being set indicates that the EC has transferred data to the EC Data Register. For another example, processor A can send a write EC register command (e.g., the command can be 0x81) to processor B through the PMC, where the address offset of an EC RAM resource is immediately after 0x81. Processor A can write data (e.g., a blue screen message) in the EC Data Register when an Input Buffer Full (IBF) signal of the EC State Register is zero. The IBF signal being zero indicates that the data in the EC Data Register has been emptied.

[0157] At step 504, processor B controls component 1 in the Codec or component 2 in the PA based on the blue screen message to mute the electronic device.

[0158] It is understood that the meanings of component 1 and component 2 can refer to the above embodiments and will not be repeated here.

[0159] In an implementation, after receiving the blue screen message, the processor B can send a control instruction to the component 1 in the codec or the component 2 in the PA to control the component 1 to switch from the high level state to the low level state or to control the component 2 to switch from the high level state to the low level state, so as to mute the electronic device.

[0160] It should be understood that, referring to FIG. 1, after the electronic device appears the blue screen phenomenon, the processor A (such as the SOC) can generate noise 1. The noise 1 can be coded and decoded by the codec to generate noise 2, at this time, the component 1 in the codec is in the high level state, and the component 1 in the high level state is used to indicate that the component 1 can work normally. For example, when the component 1 is the mute pin shown in FIG. 7, the mute pin in the high level state is used to indicate that the audio signal output is not muted, and for another example, when the component 1 is the left and right channel output pins of the speaker shown in FIG. 7, the left and right channel output pins in the high level state are used to indicate that the left and right channel output pins can normally output the audio signal. Then, the noise 2 is amplified in power by the power amplifier (PA) to a high enough level to generate noise 3, at this time, the component 2 in the PA is in the high level state, and the component 2 in the high level state is used to indicate that the component 2 can work normally. For example, when the component 2 is the mute pin shown in FIG. 8, the mute pin in the high level state is used to indicate that the audio signal output is not muted, and for another example, when the component 2 is the power pin shown in FIG. 8, the power pin in the high level state is used to indicate that the PA can be normally powered, and for another example, when the component 2 is the output pin shown in FIG. 8, the output pin in the high level state is used to indicate that the audio signal can be normally output. Then, the noise 3 is played to the outside through the speaker.

[0161] By the step 504 provided in the embodiments of the present application, the processor B can change the state of the component 1 in the Codec or the component 2 in the PA. For example, when the component 1 is the mute pin shown in FIG. 7, the processor B can control the mute pin to switch from the high level state to the low level state, and the low level state of the mute pin is used to indicate that the output of the audio signal is muted. For another example, when the component 1 is the left and right channel output pin of the speaker, the processor B can control the left and right channel output pin to switch from the high level state to the low level state, and the low level state of the left and right channel output pin is used to indicate that the noise cannot be output through the left and right channel output pin. For another example, when the component 2 is the mute pin shown in FIG. 8, the processor B can control the mute pin to switch from the high level state to the low level state, and the low level state of the mute pin is used to indicate that the output of the audio signal is muted. For another example, when the component 2 is the power pin shown in FIG. 8, the processor B can control the power pin to switch from the high level state to the low level state, and the low level state of the power pin is used to indicate that the PA is powered off, i.e., the PA cannot work normally (it can also be understood as that the PA cannot output the audio signal). For another example, when the component 2 is the output pin shown in FIG. 8, the processor B can control the output pin to switch from the high level state to the low level state, and the low level state of the output pin is used to indicate that the audio signal cannot be output.

[0162] In some embodiments, the mute pin mentioned in the above embodiments (such as the mute pin A and the mute pin B shown in FIG. 7, and the mute pin C shown in FIG. 8) is in the high level state, which can indicate that the output of the audio signal is muted, and the mute pin is in the low level state, which can indicate that the output of the audio signal is not muted. In this case, in the step 504, the processor B can control the mute pin to switch from the low level state to the high level state based on the blue screen message.

[0163] In some embodiments, the output pin mentioned in the above embodiments (such as the left and right channel output pin of the speaker, the left and right channel output pin of the earphone, the output pin shown in FIG. 8, etc.) is in the high level state, which can indicate that the audio signal cannot be output, and the output pin is in the low level state, which can indicate that the audio signal can be normally output. In this case, in the step 504, the processor B can control the output pin to switch from the low level state to the high level state based on the blue screen message.

[0164] In some embodiments, the step 501 is to connect the processor B with other components on the playing path of the noise from the inside of the electronic device to the outside, such as the mute pin, the power pin, the output pin, the input pin, etc. in the speaker, and the present application does not limit this. In the step 504, the processor B can control other components on the playing path of the noise based on the blue screen message to mute the electronic device.

[0165] Step 505, after the electronic device is restarted, the processor B controls the component 1 in the Codec or the component 2 in the PA to reset, so that the audio signal can be normally output.

[0166] It should be understood that after the electronic device appears the blue screen phenomenon, the processor B can control the component 1 in the Codec or the component 2 in the PA to reset, that is, control the component 1 in the Codec or the component 2 in the PA to switch from the low level state to the high level state, so that the audio signal can be normally output.

[0167] In the implementation, after the electronic device is restarted, the processor B can determine the state of the component 1 or the component 2 in the Codec, that is, determine whether the component 1 or the component 2 is in the high level state or the low level state, when the component 1 or the component 2 is in the high level state, there is no need to switch the state of the component 1 or the component 2. When the component 1 or the component 2 is in the low level state, the component 1 in the Codec or the component 2 in the PA needs to be controlled to switch from the low level state to the high level state, so that the audio signal can be normally output.

[0168] In some embodiments, the Codec or the PA can also include a reset pin, and the processor B can perform reset processing through the reset pin to control the component 1 in the Codec or the component 2 in the PA to switch from the low level state to the high level state.

[0169] In some embodiments, step 505 can also be that after the electronic device is restarted, the processor B controls other components on the noise playing path to reset, so that the audio signal can be normally output.

[0170] In related schemes, in the case that the electronic device appears the blue screen phenomenon, the electronic device can emit noise. Through analysis, the applicant finds that the reason why the electronic device emits noise is that: when the electronic device appears the blue screen phenomenon, it means that the operating system of the electronic device has crashed, or the hardware (such as the SOC) of the electronic device has failed (for example, the operating system corresponding to the SOC crashes, or the hardware of the SOC fails), the SOC in the electronic device can emit noise, but the hardware (such as the SOC) in the hardware layer of the electronic device cannot perceive whether the upper layer (such as the application layer shown in FIG. 3) appears the blue screen phenomenon, so that the hardware layer cannot control the components (such as the Codec and the PA) on the noise playing path shown in FIG. 1 after the upper layer appears the blue screen phenomenon, resulting in that the noise can be played through the playing path shown in FIG. 1.

[0171] In the embodiment of the present application, at the software level, the electronic device can register a callback function in the processor A, acquire the blue screen message through the callback function, and then the processor A sends the blue screen message to the processor B. Thus, compared with the related solution, even if the electronic device appears the blue screen phenomenon, the hardware layer (such as the processor B in the hardware layer) can perceive the phenomenon through the callback function and acquire the blue screen message. Subsequently, the processor B controls the component 1 in the Codec or the component 2 in the PA based on the blue screen message, so as to mute the electronic device or cut off the noise playing path, which can reduce the probability of the electronic device emitting noise or eliminate the noise emitted by the electronic device, thereby improving the user experience.

[0172] At the hardware level, the processor B can be connected with the component 1 in the Codec or connected with the component 2 in the PA. Thus, in the case that the software of the processor A crashes or the hardware fails, the processor B which can work throughout the life of the electronic device can be used to control the state of the components (such as the Codec and the PA) in the playing path shown in FIG. 1, and the processor B in the hardware layer can be used to control the state of the components in the playing path.

[0173] The above embodiment introduces the implementation process of the control method of the electronic device provided in the embodiment of the present application in combination with FIGS. 5 to 8. The following embodiment introduces the implementation process of the control method of the electronic device provided in the embodiment of the present application again in combination with the software structure in FIG. 3.

[0174] Please refer to FIG. 9, which is a timing diagram of the control method of the electronic device provided in the embodiment of the present application. The method shown in FIG. 9 includes steps 901 to 907.

[0175] In step 901, a callback function is registered in the driver module A in the driver layer, and the callback function is used to monitor the blue screen event.

[0176] The meanings of the driver module A, the callback function and the blue screen event can be referred to the above embodiments.

[0177] The implementation process of the embodiment has been described in the above embodiments, and will not be described here again.

[0178] In step 902, the application layer displays a blue screen interface.

[0179] It should be understood that the displayed blue screen interface can be the interface shown in (a) or (b) of FIG. 4.

[0180] In step 903, after the application layer displays the blue screen interface, the callback function in the driver module A can monitor the blue screen event.

[0181] In step 904, the driver module A sends a blue screen message to the processor A.

[0182] At step 905, after receiving the blue screen message, the processor A can send the blue screen message to the processor B in the hardware layer through the driver module B.

[0183] The implementation process of the processor A sending the blue screen message to the processor B can refer to the above embodiment, and details are not described herein.

[0184] At step 906, after receiving the blue screen message, the processor B can send a control instruction to the codec or the power amplifier in the hardware layer.

[0185] At step 907, the processor B controls the component 1 in the codec or the component 2 in the power amplifier to switch the level state of the component 1 and the component 2 through the control instruction.

[0186] The implementation process of the embodiment can refer to step 504 in the above embodiment, and details are not described herein.

[0197] Since the software crash or hardware failure of the first processor causes the electronic device to appear the blue screen phenomenon, the first processor cannot control the components on the noise playing path to make the electronic device emit noise when the electronic device is in the blue screen state.
