Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a commodity or system comprising such elements.

Some embodiments of the invention will now be described in detail with reference to the accompanying drawings. In the case of no conflict between the embodiments, the following embodiments and features and steps in the embodiments may be combined with each other. The sequence of steps in the method embodiments described below is only an example and is not strictly limiting.

Before describing the details provided in the following embodiments of the present invention, the details about the validity of the protection program may be further described:

as mentioned in the background, a protection program in a PC may protect speakers in the PC. The operation of the protection program of the loudspeaker can enable the loudspeaker to continuously work under the power exceeding the rated power of the loudspeaker. The protection program can realize the protection of the loudspeaker by reducing the vibration amplitude of the loudspeaker diaphragm and/or reducing the temperature of the loudspeaker. And the continuous operation of the over-rated power of the loudspeaker can provide good sound effect for users.

In practice, the protection program may also fail, and at this time, the method, system or apparatus provided in the embodiments of the present invention described below may be used to continue to provide protection for the speaker.

Alternatively, the reasons for the protection program failure may include: the user prunes the program file of the protection program. Wherein, the user's pruning can be active pruning or false pruning. The program files may include dependency files and configuration files for protecting the program, and so forth. Optionally, the reasons for the protection program failure may further include: the user directly deletes the entire protection program. Alternatively, the user may perform deletion of the protection program through the management application. The management application may be an application program such as a computer manager installed on a PC, and the application program is used for managing the whole life cycle of the protection program.

In addition, in practice, the protection program is not always invalid, and therefore, the protection program can be restored to be valid from the invalidation. Alternatively, the reason why the protection program is restored to be effective may be that the user actively restores the deleted file after discovering that the program file of the protection program was deleted by mistake. The reason for the restoration may be that the user reinstalls the speaker protection program through the management application on the PC after discovering that the protection program is deleted entirely.

It can be seen that the occurrence of changes in the program files in the protection program can result in changes in the effectiveness of the protection program. More specifically, pruning of a program file may cause a protection program to become invalid from valid, and restoration of a program file may cause a protection program to become valid from invalid.

It should be noted that, the speakers protected by the methods, systems or apparatuses according to the embodiments of the present invention are not necessarily provided on the PC. The speaker to be protected may also be installed on a different electronic device, and the program file of the protection program of the speaker in the electronic device is set to be user-modifiable. Alternatively, the electronic device may be a smart screen, a smart speaker, a smart phone, or the like.

Based on the above description, in order to facilitate solution understanding, a control procedure of the speaker may be described based on a system architecture of the electronic device.

Fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present invention. Alternatively, the electronic device in the present embodiment may be any device suitable for the present solution in the above description, such as a PC, a smart screen, or the like.

As shown in fig. 1, the electronic device may include: a main processor, a controller, a power amplifier and a speaker. The host processor may include, among other things, a monitor driver and a speaker protector.

The Power Amplifier (PA) may be specifically represented as a chip. The controller may specifically be an embedded controller (Embedded Controller, EC for short), which may also be represented as a chip.

Optionally, the electronic device further comprises an (Audio Digital Signal Processing, ADSP) audio digital signal processor for audio digital signal processing. The main processor and the audio digital signal processor may in particular be represented as chips.

As shown in fig. 1, the main processor is connected with the audio digital signal processor and the controller, and the power amplifier is connected with the audio digital signal processor, the controller and the speaker. And the main processor, the audio digital signal processor, and the controller may be packaged as one SOP (Small Out-Line Package), and the power amplifier and the speaker may be external devices to the SOP.

The main processor in the electronic device may adopt a layered architecture, an event driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. As shown in fig. 1, a software system of an electronic device provided by an embodiment of the present invention may employ a hierarchical architecture. The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. As shown in fig. 1, the software system of the electronic device may be divided into four layers, namely, an application layer, an application framework layer, an operating system layer and a hardware driving layer from top to bottom. The main processor of the electronic device performs data calculation based on the software architecture.

The application layer may include a series of application packages. As shown in FIG. 1, the application layer may include applications such as a browser, a computer manager, notes, photos, a media player, and the like.

The application framework layer provides an application programming interface (ApplicationProgramming Interface, abbreviated API) and programming framework for the application of the application layer. The application framework layer includes a number of predefined functions.

As shown in FIG. 1, the application framework layer may include a view system and its interfaces, a graphics system and its interfaces, and other system services. Other system services may specifically include: window manager, content provider, resource manager, notification manager, etc.

The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, a display interface including a message notification icon may include a view displaying text and a view displaying a picture.

The window manager is used for managing window programs. The window manager can acquire the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

The content provider is used to store and retrieve data and make such data accessible to applications. The data may include video, images, audio, browsing history, bookmarks, and the like.

The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like.

A notification manager for managing and displaying notification messages from different applications and systems. The notification manager can help users to timely learn and process important events, reminders, and messages. Such as notification manager is used to inform that the download is complete, message alerts, etc.

The application layer and the application framework layer both run in dependence upon the operating environment provided by the operating system. The operating system is responsible for distributing computer resources, managing processes and threads, providing basic functions such as file system access, and providing an interactive interface with hardware devices. The application layer and application framework layer run and execute tasks through these interfaces and functions provided by the operating system.

The operating system layer is typically made up of a number of functional modules, such as: process management, memory management, file systems, device drivers, user interfaces, network communications, security management, system scheduling, and the like.

The hardware driver layer is a layer between hardware and software. The hardware driver layer may include at least a display driver, a camera driver, an audio driver, a sensor driver, a protection program, and the like. In the embodiment of the present invention, in order to continue to provide protection for the speaker when the protection program fails, the hardware driver layer may be further added with a monitoring driver for monitoring whether the protection program is valid. The protection program and the monitoring driver in the hardware driver layer are the drivers which are mainly used in the scheme.

Based on the above software architecture, the control procedure of the electronic device on the speaker can be generally described as:

in response to the audio playback, the monitor driver in the hardware driver layer may obtain an operational state corresponding to the protection program of the speaker. The operating conditions may include normal and abnormal. Normal operation indicates that the protection program may provide protection to the speaker to keep the speaker operating at a power higher than the rated power. Abnormal operation indicates that the protection program cannot provide protection to the speaker, and that continued operation of the speaker at a power higher than the rated power may cause damage to the speaker. Alternatively, the operating state may be reflected in operating data, which in turn may be embodied as key value data in a registry.

Based on the acquired operational status, the monitoring driver may further notify the controller of the operational status. The controller can control the working power of the loudspeaker according to the received running state so as to realize the protection of the loudspeaker. Specifically, when the operation state of the protection program is abnormal, the controller can control the loudspeaker to work under the power smaller than the rated power, namely, the protection of the loudspeaker is realized by the cooperation of the monitoring driver and the controller. When the operation state of the protection program is normal, the protection controller can control the loudspeaker to work under the power higher than the rated power, and the protection program can protect the loudspeaker.

The control procedure of the loudspeaker by the electronic device will be described in detail below.

The user may trigger an audio playback operation, after which the electronic device may implement audio playback through the speaker via the audio driver in the hardware driver layer in response to this operation.

Alternatively, the user may trigger an audio playback operation in an application layer that provides audio playback functionality, such as a music application, a video application, etc., and the application layer in the electronic device may respond to the playback operation.

The process of the audio driver driving the speaker to play audio can be described as follows: after the audio driver is running, a lower power audio signal may be generated. The power amplifier connected with the loudspeaker can further amplify the power of the low-power audio signal, when the power of the amplified audio signal reaches the driving power of the loudspeaker, the loudspeaker starts to amplify the audio, and at the moment, the user can hear the audio.

During the audio playing process, the protection program in the hardware driving layer is also driven to run so as to protect the loudspeaker, namely, the loudspeaker can continuously work under the power exceeding the rated power of the loudspeaker and is not burnt. It is also because the speaker is continuously operated at a high power exceeding the rated power, and thus the speaker can provide a good sound effect to the user.

During audio playback, the speaker protection program may be active, or may be suddenly inactive for some time, and such an invalidation may be maintained for some time. Specific reasons for failure may be found in the above-mentioned related descriptions and will not be described in detail herein. The monitoring driver in the hardware driver layer can perform continuous monitoring of the effectiveness of the protection program. Alternatively, such continuous monitoring may be periodic or may be in response to a user continually triggering operation.

Specifically, during the audio playing process, the monitoring driver may obtain state data corresponding to the protection program of the speaker. The status data is used to reflect the running status of the protection program, i.e. whether the protection program is invalid. When the acquired state data is a first preset value reflecting the failure of the protection program, the monitoring driver may generate a first notification and send the first notification to the controller of the electronic device.

Alternatively, the status data acquired by the monitor driver may be specifically represented as key value data recorded in the registry. The first preset value may be set to 0.

Alternatively, the monitoring driver may call its own callback function and read status data representing key value data from the registry according to the path of the registry contained in the callback function. Alternatively, the callback function may be a CmRegisterCallback function. The callback function may be created when the monitor driver is written and registered in the hardware driver layer of the electronic device when the monitor driver is running. And optionally the callback function is re-registered each time the electronic device is started. Alternatively, the name of the key value data recorded in the registry may be mec_state. Alternatively, the path of the REGISTRY may be REGISTRY\USER\S-1-5-19\Software\AWinicAPO.

The controller of the electronic device may then receive a first notification generated by the monitoring driver. The controller is responsive to the first notification to determine that the protection program of the speaker is disabled, and the controller may further control a preset pin (e.g., GAIN0 pin) of a power amplifier coupled to the speaker to be low.

Since the amplification factor of the power amplifier is reduced at a low level, the operating power of the speaker can be reduced to make the operating power of the speaker lower than the rated power. At this time, damage is not likely to occur even if the speaker is continuously operated.

For controlling the level of the preset pin, optionally, after the controller receives the first notification, the controller may modify data in a preset address in its shared memory to control the level of the preset pin, and optionally, the shared memory is shared by the controller and the underlying software in the electronic device.

In this embodiment, during the process of playing audio, the monitor driver may obtain status data corresponding to the protection program of the speaker, where the status data may reflect whether the protection program of the speaker is effective, that is, reflect that the speaker is easy to damage when continuously working at a power greater than the rated power. The monitoring driver may generate a first notification when the status data is a first preset value reflecting a failure of the protection program. The controller responds to the first notice to control a preset pin of a power amplifier connected with the loudspeaker to be at a low level, so that the amplification factor of the power amplifier is reduced, and the loudspeaker is enabled to continuously work under a first power smaller than rated power.

In the control process, when the monitoring driver determines that the protection program fails, the controller responds to the notification of the monitoring driver, and the amplification factor of the power amplifier can be reduced by adjusting the level value of the pin of the power amplifier, so that the working power of the loudspeaker is reduced, the possibility of damage to the loudspeaker is reduced, and the protection to the loudspeaker is realized.

In summary, when the protection procedure is effective, the protection of the loudspeaker may be achieved by reducing the amplitude of the vibrations of the loudspeaker diaphragm and/or by reducing the temperature of the loudspeaker. When the protection program is invalid, the protection of the loudspeaker can be realized by reducing the working power of the loudspeaker in the mode of the embodiment shown in fig. 1.

According to the embodiment shown in fig. 1, the monitoring driver can continuously monitor the validity of the protection program. And for any one of the processes of continuous monitoring it may be performed in the manner of the embodiment shown in figure 1.

When the previous monitoring determines that the protection program fails, the controller may reduce the speaker operating power by changing the power amplifier pin level value to continue to protect the speaker, as shown in fig. 1. The failure of the protection program in this case can be classified into two cases:

The state data of the protection program acquired by the monitoring driver when the monitoring driver performs the last monitoring or continuously monitors for several times is a first preset value, namely, the protection program is invalid when the monitoring driver performs at least one monitoring before the last monitoring, namely, the state data of the protection program keeps the first preset value unchanged before and after the controller responds to the first notification, namely, the protection program is always in an invalid state in the adjacent at least one monitoring process. At this time, the controller controls the preset pin of the power amplifier to be at a low level, which is to maintain the level of the preset pin at a low level.

In this case, the cooperative operation of the monitor driver and the controller may provide protection for the speaker during the period that the protection program is continuously inactive.

In another case, the state data of the protection program obtained by the monitoring driver during the previous monitoring is a second preset value reflecting the validity of the protection program, that is, before the controller responds to the first notification, the state data of the protection program is converted from the second preset value to the first preset value, that is, the state of the protection program is changed from valid to invalid during the two adjacent monitoring processes. At this time, the controller controls the preset pin of the power amplifier to be low level, which is to change the level value of the preset pin from high level to low level. Alternatively, the second preset value may be set to 1.

In this case, the cooperative operation of the monitor driver and the controller may continue to provide protection to the speaker when the protection program transitions from active to inactive.

In practice, the protection program of the speaker is not always in an inactive state, and when the protection program of the speaker is in an active state, the control process of the electronic device on the speaker may be further described as:

during the audio playing process, the monitoring driver may obtain state data corresponding to the protection program of the speaker. When the acquired state data is a second preset value reflecting that the protection program is valid, the monitoring driver can generate a second notification and send the second notification to the controller of the electronic device. Alternatively, the representation and the acquisition of the status data may be described with reference to the embodiment shown in fig. 1.

The controller of the electronic device may then receive a second notification generated by the monitoring driver. The controller may further control the preset pin of the power amplifier connected to the speaker to be high in response to the second notification to determine that the protection procedure of the speaker is valid. Because the amplification factor of the power amplifier can be increased under the high level, the working power of the loudspeaker can be improved, the working power of the loudspeaker can be higher than rated power, and the loudspeaker can provide good sound effect for users.

Optionally, after the controller receives the second notification, the controller may modify the data in the preset address in the shared memory to control the level of the preset pin.

In this embodiment, when the monitor driver determines that the protection program is effective, the controller may enable the speaker to operate at a power exceeding the rated power by controlling the level value of the pin of the power amplifier, thereby providing a good sound effect for the user.

Similar to the protection program failure described above, in the process of continuously monitoring the effectiveness of the protection program by the monitoring drive program, when the protection program is determined to be effective by the current monitoring, the controller can enable the speaker to operate at a power exceeding the rated power by controlling the pin level value of the power amplifier. The effectiveness of the protection procedure in this case can be divided into two cases:

the state data of the protection program acquired by the monitoring driver when the monitoring driver performs the previous monitoring or continuously performs several times of monitoring is a second preset value, namely the protection program is valid during at least one monitoring before the previous monitoring, namely the state data of the protection program is kept unchanged after the controller responds to the second notification, namely the protection program is always in a valid state during at least one adjacent monitoring. At this time, the controller controls the preset pin of the power amplifier to be at a high level, which is effective to maintain the level of the preset pin at a high level.

In this case, the cooperative operation of the monitor driver and the controller may enable the speaker to operate continuously at an over-rated power during the duration of the protection procedure to provide a good sound effect to the user.

In another case, the state data of the protection program acquired by the monitoring driver during the previous monitoring is a first preset value reflecting that the protection program is invalid, that is, the state data of the protection program is changed from the first preset value to a second preset value before the controller responds to the second notification, that is, the state of the protection program is changed from invalid to valid during the adjacent monitoring. At this time, the controller may control the preset pin of the power amplifier to be at a high level, which is to switch the level value of the preset pin from a low level to a high level.

In this case, the cooperative operation of the monitor driver and the controller can make the speaker continuously operate under the over-rated power when the protection program is recovered from invalid to valid, so as to provide good sound effect for the user.

In the embodiments described above, the monitoring of the effectiveness of the protection program by the monitoring driver may be implemented by means of status data. Then, optionally, for the status data, it may be generated by a protection program.

Specifically, the play protection program responsive to audio also starts running. In the running process of the protection program, the protection program can detect whether the protection program is effective or not by calling a callback function of the protection program, so that state data is obtained. Alternatively, the status data may be represented as key value data and written into a registry of the electronic device.

When the state data is specifically key value data in the registry, if the protection program fails, the protection program writes the key value data of a first preset value in the registry; if the protection program fails, the protection program writes key value data of a second preset value in the registry.

In order to distinguish the callback function used for acquiring the state in the monitoring driver from the callback function in the protection program, the callback function in the protection program may be referred to as a first callback function, and the callback function in the monitoring driver may be referred to as a second callback function.

For the specific working process of the first callback function, optionally, by executing the first callback function, the protection program can query whether the program file of the protection program stored in the electronic device is complete or not, and can also query whether the configuration parameters in the program file are correct or not. It will be readily appreciated that the integrity of the program file and the correctness of the parameters can reflect whether and in what direction the program file is modified.

If the program file is complete and the configuration parameters are correct, which indicates that the program file is not modified or the program file is modified to be correct by an error, the function execution result output by the first callback function indicates that the protection program is effective, and the key value data written in the registry by the protection program is a second preset value. If the program file is incomplete and/or the configuration parameters are wrong, the program file is modified and the program file is modified into errors, the function execution result output by the first callback function indicates that the protection program is invalid, and the key value data written in the registry by the protection program is a first preset value.

Alternatively, the protection program may continuously monitor its own availability as with the drive monitor program. Such continuous monitoring may be periodic or may be in response to a user continually triggering operation. And optionally the monitoring period of the protection program may be the same as or different from the monitoring period of the monitoring driver.

When the protection program is invalid due to the user deleting the program file of the protection program, the method provided by the embodiment can be used, that is, the protection program can monitor the validity of the protection program by querying the file.

In this embodiment, the protection program may monitor its own validity, and write the monitoring result into the registry. Thereafter, the monitoring driver may determine the validity of the protection program by reading the data in the registry. That is, the protection program directly monitors the effectiveness of the protection program, and the monitoring driver indirectly monitors the effectiveness of the protection program. In addition, by means of the monitoring function of the protection program, the effectiveness of the protection program can be determined by the monitoring driver in a form of directly reading data, so that the monitoring logic of the monitoring driver can be simplified, and the development difficulty of the monitoring driver is reduced.

When the user directly deletes the protection program through the management application program to cause the protection program to be invalid, the protection program validity can also be optionally monitored by other programs in the electronic device, such as the management application program. In particular, the management application may continuously monitor the installation of different types of programs in the electronic device.

When the management application monitors that the protection program is not installed in the electronic device, the management application may write key value data reflecting that the protection program is invalid in the registry. The monitor driver may read the key value data and implement protection of the speaker by controlling a preset pin of the power amplifier to be low. The specific process may be referred to the description of the related embodiments, and will not be repeated here.

When the management application program monitors that the protection program is installed in the electronic device, the protection program can further monitor the running state directly, and then the protection program or the monitoring driver and the controller protect the loudspeaker according to the modes provided by the embodiments.

In combination with the above embodiments, the cooperative work of the monitor driver, the protection program, the controller and the power amplifier can realize the control of the working power of the speaker according to the effectiveness of the protection program. The control of the working power of the loudspeaker can also realize that the loudspeaker provides good sound effect for users when the protection program is effective; when the protection program fails, the working power of the loudspeaker is reduced, and the possibility of burning the loudspeaker is reduced.

In addition, in the electronic device shown in fig. 1 or fig. 4, the components for realizing speaker protection may also constitute a speaker control system. The system can be considered as a soft and hard combined system. Fig. 5 is a schematic structural diagram of a speaker control system according to an embodiment of the present invention. As shown in fig. 5, the system includes a monitor driver, a controller, a power amplifier, and a speaker.

The power amplifier is respectively connected with the controller and the loudspeaker; the controller is connected with the monitoring driver.

Optionally, the speaker control system may further include a protection program for the speaker.

And responding to the playing of the audio, and acquiring state data corresponding to the protection program of the loudspeaker by the monitoring driver.

Optionally, when the status data is a first preset value reflecting failure of the protection program, the monitoring driver generates a first notification and sends the first notification to the controller. The controller responds to the first notice and controls a preset pin of a power amplifier connected with the loudspeaker to be low level, so that the working power of the loudspeaker is smaller than rated power, and the possibility of burning the loudspeaker is reduced.

Optionally, when the status data is a second preset value reflecting that the protection program is valid, the monitoring driver generates a second notification and sends the second notification to the controller. The controller responds to the second notice and controls the preset pin of the power amplifier connected with the loudspeaker to be high level, so that the working power of the loudspeaker is higher than the rated power, and good sound effect is provided for a user. At this time, protection is provided for the speaker by the protection program.

In this embodiment, the monitor driver may obtain status data corresponding to the protection program of the speaker, where the status data may reflect whether the protection program of the speaker is valid. The monitoring driver may generate a first notification when the status data is a first preset value reflecting a failure of the protection program. The controller responds to the first notification to control a preset pin of a power amplifier connected with the loudspeaker to be at a low level, so that the amplification factor of the power amplifier is reduced, the loudspeaker continuously works at a power smaller than rated power, namely the working power of the loudspeaker is reduced, the damage possibility of the loudspeaker is reduced, and the protection of the loudspeaker is realized.

In addition, the details and the technical effects that can be achieved in this embodiment are all referred to in the above embodiments, and are not described herein.

Alternatively, the state data in the embodiment shown in fig. 5 may specifically be key value data in a registry, where the key value data may be written by a protection program. The process of writing key value data by the protection program and various situations of the validity transformation of the protection program can be referred to the related descriptions in the embodiments shown in fig. 1 to 3, and are not repeated here.

The control procedure of the loudspeaker can also be described below from a method point of view. Fig. 6 is a flowchart of a method for controlling a speaker according to an embodiment of the present invention. The text generation method provided by the embodiment of the invention can be executed by the electronic equipment provided by the embodiment. As shown in fig. 6, the method may include the steps of:

s101, responding to the playing of the audio, and acquiring state data corresponding to a protection program of the loudspeaker.

S102, when the state data is a first preset value reflecting the failure of the protection program, a first notification is generated.

S103, responding to the first notice, and controlling a preset pin of a power amplifier connected with the loudspeaker to be low level, so that the working power of the loudspeaker is smaller than the rated power.

And the electronic equipment responds to the playing of the audio to acquire the state data corresponding to the protection program of the loudspeaker. The status data is used to reflect whether the protection procedure of the speaker is valid. The protection program effectively indicates that the loudspeaker continuously works under the power higher than the rated power and is not easy to burn.

Alternatively, the state data may be embodied as key value data written into a registry. The electronic device may read the key value data from the registry by calling a callback function to determine if the protection program is valid. And optionally the callback function for reading the key-value data needs to be re-registered each time the electronic device is started.

For the acquired status data, the present embodiment gives a case: when the state data is a first preset value reflecting the failure of the protection program, the electronic device generates a first notification, and controls a preset pin of a power amplifier connected with the loudspeaker to be at a low level in response to the first notification. At low levels, the speaker may operate at less than rated power, thereby reducing the likelihood of the speaker burning out.

Alternatively, in this embodiment, the protection program may be in an invalid state before and after the first notification is generated, or may be changed from valid to invalid. In either case, however, the electronic device may operate the speaker at a power below the rated power by controlling the pin level.

Alternatively, the steps in the present implementation may be specifically performed by a monitoring driver in the electronic device.

In this embodiment, the electronic device may obtain state data corresponding to the protection program of the speaker, where the state data may reflect whether the protection program of the speaker is valid. When the state data is a first preset value reflecting failure of the protection program, a first notification can be generated and responded to control a preset pin of a power amplifier connected with the loudspeaker to be at a low level, so that the amplification factor of the power amplifier is reduced, the loudspeaker continuously works at a power smaller than rated power, namely, the working power of the loudspeaker is reduced, the damage possibility of the loudspeaker is reduced, and the protection of the loudspeaker is realized.

Fig. 7 is a flowchart of another speaker control method according to an embodiment of the present invention. As shown in fig. 7, the following steps may be included:

s201, responding to the playing of the audio, and acquiring state data corresponding to a protection program of the loudspeaker.

The specific implementation process of the above step S201 may refer to the specific description of the related steps in the embodiment shown in fig. 6, which is not repeated herein.

S202, when the state data is a second preset value reflecting that the protection program is valid, a second notification is generated.

S203, responding to the second notice, and controlling a preset pin of the power amplifier to be set to be high level, so that the working power of the loudspeaker is larger than the rated power.

Corresponding to the embodiment shown in fig. 6, this embodiment gives another case: when the state data is a second preset value reflecting the failure of the protection program, the electronic device generates a second notification, and controls a preset pin of a power amplifier connected with the loudspeaker to be at a high level in response to the second notification. At high levels, the speaker may continue to operate at power exceeding the rated power, providing good sound effects to the user, and the speaker is also not easily burned.

Alternatively, in this embodiment, the protection program may be in an active state before and after the second notification is generated, or may be changed from inactive to active. In either case, however, the electronic device may operate the speaker at a power exceeding the rated power by controlling the pin level.

In this embodiment, the electronic device may obtain state data corresponding to a protection program of the speaker. When the state data is a second preset value reflecting the effectiveness of the protection program, a second notification can be generated and responded to control the preset pin of the power amplifier connected with the loudspeaker to be at a high level, so that the amplification factor of the power amplifier is improved, and the loudspeaker continuously works under the power higher than the rated power, so that good sound effect is provided for a user. Meanwhile, since the protection program is effective at this time, protection can be provided for the speaker.

The state data in the embodiments shown in fig. 6 and 7 may be embodied as key value data written into a registry. Alternatively, the writing of the key value data may also be performed by the electronic device.

Specifically, in response to playing audio, the electronic device may determine whether the protection program is valid by calling a callback function, and then determine key value data written in the registry according to the determination result. Alternatively, according to the actual situation, the validity of the protection program may be implemented by means of a callback function in the protection program or the management application program in the electronic device, and the specific process may be referred to as the description in the above related embodiments. For distinguishing, the callback function used for determining the validity of the protection program may be called a first callback function, and the callback function used for reading the key value data may be called a second callback function.

And when the protection program is determined to be invalid, writing a first preset value in the registry. And when the protection program is determined to be effective, writing a second preset value in the registry.

And in view of the foregoing description of the method embodiment, the control flow of the electronic device to the speaker may also be understood in conjunction with the flowchart shown in fig. 8.

The control process of the speaker has been described in detail above from the viewpoint of the apparatus, system and method. The control process of the speaker can be described below by taking a specific application scenario in which the PC plays audio as an example.

An audio application and a protection program for speakers may be installed in the PC, and a program file of the protection program is set to be user-modifiable.

In practice, in one case, the user may delete at least one program file of the protection program or modify parameters in the program file by mistake during the manual system cleaning.

Under the above situation, the user can still trigger the operation on the audio application program in the PC under the condition that the protection program has failed, so as to realize audio playing.

During the audio playing process, the protection program in the hardware driving layer of the PC can monitor the effectiveness of the protection program, in particular, the protection program can determine whether the program file is complete and whether the parameters in the file are correct in a query mode. The protection program may then write key value data reflecting the validity of the protection program to the registry based on the monitored validity. Under the above situation, the protection program determines that the program file is incomplete and/or the parameters in the file are wrong in a query mode, so that the protection program is invalid, and the key value data written into the registry by the protection program is 0.

The monitor driver in the PC hardware driver layer may further read key data reflecting the failure of the protection program from the registry and further generate a notification. The controller in the PC can respond to the notification to control the pin of the power amplifier connected with the loudspeaker to be at a low level, thereby reducing the working power of the loudspeaker, reducing the possibility of burning out the loudspeaker, namely realizing continuous protection of the loudspeaker when the protection program fails.

Optionally, the user may also actively restore the misshapen program file and/or parameters, and the protection program may monitor that the misshapen program file is restored, at which point the protection program may modify the key value data in the registry to 1. Then, the monitoring driver can know that the protection program has been restored to be effective by reading the key value data in the registry, and can send a notification to the controller so that the controller controls the pin of the power amplifier to be at a high level, and the loudspeaker operates at a power exceeding the rated power. At this time, since the protection program is restored to be effective, the protection program can provide protection for the speaker, and the speaker also provides good sound effects for the user.

In another case, the user may also directly delete the whole protection program by mistake in the process of manually cleaning the system. Alternatively, the user may trigger the false deletion of the protection program by a computer manager installed on the PC.

In the above case, when the user triggers an operation on the audio application, the playback of the audio is responded. During the audio playing process, the effectiveness of the protection program can be monitored by a computer manager in the PC. The validity at this time is specifically whether or not the protection program of the speaker is reinstalled in the PC. The computer manager may write key value data reflecting the validity of the protection program to the registry. The monitoring driver in the PC can also control the level of the pins of the power amplifier in a meter reading mode, so that the protection of the loudspeaker is realized.

The working processes not specifically described in the above cases may be referred to the relevant descriptions in the above embodiments, and are not repeated here.
