Of course, when the number of the speakers 130 is plural, the position where each speaker 130 is disposed may not be limited.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for controlling a speaker according to an embodiment of the present application. In a specific embodiment, the speaker control method is applied to the speaker control apparatus 400 shown in fig. 6 and the mobile terminal 100 (fig. 7) equipped with the speaker control apparatus 400. The mobile terminal comprises a plurality of loudspeakers and a sensor used for collecting scene data of a scene where the mobile terminal is located, and the loudspeakers are used for generating stereo sound effects when working together. The following will describe a specific flow of the present embodiment by taking a mobile terminal as an example. As will be described in detail with respect to the flow shown in fig. 2, the method for controlling a speaker may specifically include the following steps:

step S110: and when the mobile terminal plays audio through the loudspeaker, detecting the power consumption of the mobile terminal.

In the embodiment of the application, the mobile terminal can detect the condition of playing audio, and when the condition of playing audio is detected, determine whether to output sound by the loudspeaker. The mobile terminal can detect whether an application plays audio or whether an audio decoder works, and the like, and determine whether the audio is played. In some manners, when the mobile terminal detects that the mobile terminal is in an audio playing condition, it may detect whether an external audio playing device (e.g., a wired headset, a bluetooth sound device, etc.) is connected, and if the mobile terminal is not connected with an external audio part device, the mobile terminal may play audio using a speaker, so that it may be determined that the mobile terminal currently plays audio through the speaker; in other manners, the mobile terminal may also determine a current sound output mode (e.g., an earphone mode, a play-out mode, etc.), and if the current sound output mode is the play-out mode, it may be determined that the mobile terminal is currently playing audio through the speaker.

In the embodiment of the application, when the mobile terminal plays audio through the loudspeaker, the power consumption of the mobile terminal can be detected to determine the condition that the power consumption of the mobile terminal is larger, so that the power consumption caused by the loudspeaker can be reduced by subsequently adjusting the output power of the loudspeaker.

In some embodiments, the mobile terminal may determine its current power consumption by detecting a power consumption condition, an internal temperature condition, an operating condition of a sensor with large power consumption, and the like. And the mobile terminal can detect whether the power consumption is larger than the specified power consumption, wherein the power consumption represents the situation that the power consumption of the mobile terminal is larger and the current power consumption needs to be reduced. As an embodiment, the mobile terminal may count power consumption in a specified time period before the current time to determine the current power consumption of the mobile terminal, where the specified time period may be 10 minutes, 20 minutes, and the like, and is not limited herein. After determining the current power consumption, the mobile terminal may compare the current power consumption with the specified power consumption to determine whether the current power consumption of the mobile terminal is larger, wherein if the power consumption of the mobile terminal is larger than the specified power consumption, the current power consumption of the mobile terminal may be determined to be larger. The specific value specifying power consumption may not be limiting. As another embodiment, the mobile terminal may detect the temperature inside the mobile terminal, and regard a case where the temperature is greater than a specified temperature as a case where the power consumption is greater than a specified power consumption, that is, as a case where the power consumption is greater, where a specific value of the specified temperature may not be limited, and may be, for example, 30 degrees, 35 degrees, and the like. As another embodiment, the mobile terminal may detect an application running thereon, determine current power consumption according to power consumption occupied by the application in the past running, and compare the current power consumption with the specified power consumption to determine whether the current power consumption of the mobile terminal is larger; as another implementation manner, the mobile terminal may determine, according to power consumption occupied by the application in the past operation, a target application whose power consumption during operation is greater than specified power consumption, and determine, each time the mobile terminal determines whether current power consumption is greater than the specified power consumption, whether the target application is in an operation state, and if the target application is in the operation state, determine that the power consumption of the mobile terminal is greater than the specified power consumption. As still another embodiment, the mobile terminal may detect whether a sensor with large power consumption therein is working, for example, may detect whether a GPS (Global Positioning System) sensor is in a working state, and if in the working state, determine that the power consumption of the mobile terminal is greater than a specified power consumption. Of course, the manner of specifically determining whether the power consumption of the mobile terminal is greater than the specified power consumption may not be limited.

Step S120: and when the power consumption of the mobile terminal is larger than the specified power consumption, acquiring scene data through the sensor.

In some embodiments, when the mobile terminal determines that the power consumption of the mobile terminal is greater than the specified power consumption, scene data may be collected by a sensor to determine a current scene and reduce the power of a speaker according to the current scene. The mobile terminal can control the sensor for acquiring the scene data of the scene where the mobile terminal is located to work so as to acquire the scene data of the scene where the mobile terminal is located, and the acquired scene data is obtained from the sensor. The scene data is used for the mobile terminal to determine the scene where the mobile terminal is located so as to control the operation of the loudspeaker according to the scene where the mobile terminal is located. The scene data can be used for determining the current scene where the mobile terminal is located, and the scene data can be used for representing the requirement condition of the mobile terminal for the stereo sound effect, that is, the requirements of different scenes for the stereo sound effect are different, so that the scene where the mobile terminal is located can be determined subsequently, the output power of the loudspeaker can be controlled according to different scenes, the stereo sound effect of the scene can be met by the loudspeaker, and meanwhile, the power consumption of the loudspeaker is reduced.

In some embodiments, the scene data may include gravity sensing data of the mobile terminal, motion data of the mobile terminal, and the like, and the scene data may reflect a requirement of a use state of the mobile terminal for a stereo sound effect, so that a current scene where the mobile terminal is located may be determined.

Of course, the scene data may also be used to represent an influence of the current scene on sound propagation, that is, different scenes have different influence on sound propagation, and the scene data may also include an environmental sound of a scene where the mobile terminal is located, an environmental brightness of the scene where the mobile terminal is located, a location where the mobile terminal is located, and the like.

Step S130: and determining the current scene of the mobile terminal according to the scene data, wherein different scenes have different requirements on the stereo sound effect.

In the embodiment of the application, after the mobile terminal acquires the scene data, the current scene where the mobile terminal is located can be determined according to the scene data, and the scene can be divided according to different requirements on the stereo sound effect, so that the mobile terminal can subsequently determine the scene with different requirements on the stereo sound effect according to the scene data. The mobile terminal can pre-store scenes with different requirements for the stereo effect, and can compare the scene data with scene data corresponding to different scenes according to the scene data to determine the current scene where the mobile terminal is located. For example, the mobile terminal also stores the corresponding relationship between different scenes and scene data, and the current scene where the mobile terminal is located can be determined by using the acquired scene data and the corresponding relationship; for another example, a scene recognition model trained in advance is set in the mobile terminal, and the scene recognition model is obtained by training an initial model with a large amount of training data, where the training data may include a plurality of pieces of scene data and a scene labeled to each piece of scene data, and the mobile terminal may input the obtained pieces of scene data to the scene recognition model, so as to obtain a current scene where the mobile terminal is located.

Step S140: according to the current scene, at least one loudspeaker of the at least two loudspeakers is turned off, and/or the volume of at least one loudspeaker is reduced.

In some embodiments, at least one of the at least two speakers may be turned off and/or the volume of at least one speaker may be reduced depending on the determined current scene, since different scenes may have different requirements for the stereo effect. The mobile terminal can reduce the output power of the loudspeaker by different sizes according to different scenes according to different requirements of different scenes on the stereo effect. For example, for a scene that does not require stereo sound effect, at least one speaker may be turned off, or the volume of other speakers may be reduced while at least one speaker is turned off; for scenes where a stereo sound effect is desired, the volume of at least one speaker may be reduced. Therefore, the sound output by the loudspeaker after the output power is reduced can meet the requirement of a scene on the stereo sound effect, the requirement of a user on the playing effect of the audio is met, the power consumption caused by the loudspeaker is reduced, the power consumption of the mobile terminal is effectively reduced, the situation that the power consumption of the mobile terminal is large is avoided, and the cruising ability of the mobile terminal is improved.

The control method of the loudspeaker provided by the embodiment of the application, when the power consumption of the mobile terminal is larger than the specified power consumption, according to the difference of the demands of the scene where the mobile terminal is located on the stereo sound effect, the loudspeaker is closed and/or the volume of the loudspeaker is reduced, so that under the scene where the demands on the stereo sound effect are different, the sound output by the loudspeaker of the mobile terminal can be matched with the scene, the demands of the scene on the stereo sound effect are met, the demands of a user on the audio playing effect are met, the power consumption of the mobile terminal is effectively reduced, the situation that the power consumption of the mobile terminal is large is avoided, and the cruising ability of the mobile terminal is improved.

Referring to fig. 3, fig. 3 is a flow chart illustrating a method for controlling a speaker according to another embodiment of the present application. The method for controlling the speaker is applied to the mobile terminal, and will be described in detail with respect to the flow shown in fig. 3, and the method for controlling the speaker may specifically include the following steps:

step S210: and when the mobile terminal plays audio through the loudspeaker, detecting the power consumption of the mobile terminal.

In the embodiment of the present application, step S210 may refer to the contents of the foregoing embodiments, which are not described herein again.

Step S220: and when the power consumption of the mobile terminal is larger than the specified power consumption, acquiring scene data through the sensor.

In this embodiment of the present application, when the mobile terminal detects that audio is played through a speaker, before performing steps S210 to S250, it may further be determined whether the mobile terminal is in a preset control mode, where the preset control mode is used to control power consumption of the speaker; if the mobile terminal is in the preset control mode, the process from step S210 to step S250 is executed, and if the mobile terminal is not in the preset control mode, the process may be ended. The preset control mode can be turned on or turned off according to the operation of a user, and the requirements of different users can be met by setting the preset control mode, for example, the user does not want the mobile terminal to control the output power of the loudspeaker, and when the user wants to control the output power by the mobile terminal, the preset control mode can be turned off; and the user hopes that the mobile terminal controls the output power of the loudspeaker, and saves the power consumption of the mobile terminal, and can select to start the preset control mode.

Step S230: and determining the current scene of the mobile terminal according to the scene data, wherein different scenes have different requirements on the stereo sound effect.

In some implementations, the scene data can include gravity sensing data. The mobile terminal determines the current scene according to the scene data, and the method comprises the following steps: when the mobile terminal is detected to be in a horizontal screen state according to the gravity sensing data, determining that a current scene where the mobile terminal is located is a scene needing stereo sound effect; and when the mobile terminal is detected to be in a vertical screen state according to the gravity sensing data, determining that the current scene where the mobile terminal is located is a scene with the non-required stereo sound effect.

In this embodiment, if the mobile terminal is in a landscape state, i.e. the screen of the mobile terminal is in a landscape mode, in this case, the mobile terminal is usually playing music, video and game scenes, so that the user usually needs to play a stereo sound; and mobile terminal is in the state of putting of erecting the screen, and when mobile terminal's screen was in the mode of erecting the screen promptly, under this condition, mobile terminal was for output condition such as suggestion audio frequency, conversation audio frequency most of the time, therefore mobile terminal was when erecting screen broadcast state, need not carry out stereophonic broadcast most of the time. Therefore, whether the current scene is the scene requiring the stereo sound effect can be determined according to the horizontal screen placing state or the vertical screen placing state of the mobile terminal. A gravity sensor may be provided in the mobile terminal. The mobile terminal can determine that the mobile terminal is in a horizontal screen placing state or a vertical screen placing state according to the gravity change detected by the gravity sensor.

In other embodiments, the scene data may include motion data. The mobile terminal determines the current scene of the mobile terminal according to the scene data, and the method comprises the following steps: when the mobile terminal is detected to be in a static state according to the motion data, determining that the current scene where the mobile terminal is located is a scene needing stereo sound effect; and when the mobile terminal is detected to be in a moving state according to the motion data, determining that the current scene where the mobile terminal is located is a scene with the non-required stereo sound effect.

In this embodiment, when the mobile terminal is in a mobile state, the mobile terminal is usually in a walking state, a running state, or the like, and at this time, the user often does not have a requirement on the stereo sound effect, so that when the mobile terminal is in the mobile state, it can be determined that the current scene is a scene requiring the stereo sound effect; otherwise, when the mobile terminal is in a motion state, it may be determined that the current scene where the mobile terminal is located is a scene of the sound effect of the non-required stereo. The mobile terminal can determine that the mobile terminal is in a static state or a moving state according to the angular velocity data detected by the gyroscope sensor, the acceleration data detected by the acceleration sensor and the like.

Of course, the specific detection mode of the scene where the mobile terminal is located may not be limited.

Step S240: and when the current scene is a scene with the non-demand stereo sound effect of the mobile terminal, closing at least one loudspeaker of the at least two loudspeakers.

In the embodiment of the application, after the mobile terminal determines the current scene where the mobile terminal is located, the mobile terminal may manage and control at least two speakers according to the current scene. Specifically, when the current scene is a scene in which the mobile terminal is in an undesirable stereo sound effect, at least one speaker is turned off. Since the stereo sound effect is not required in the current scene, one or more speakers may be selected to be turned off to reduce power consumption caused by the speakers. In addition, in some scenarios, it may even be possible to leave only one speaker (e.g., the main speaker) active, while choosing to turn off the other speakers to further reduce power consumption.

In some embodiments, considering that a user may also need a stereo sound effect in some special cases, and the user needs the stereo sound effect usually when multimedia audio is played, the mobile terminal may determine the audio type of the audio when the current scene is a scene without the need for the stereo sound effect; performing turning off at least one speaker of the at least two speakers when the audio type is other than the multimedia audio type; when the audio type is the multimedia audio type, the at least two loudspeakers are controlled to work simultaneously, and the volume of the at least one loudspeaker is reduced, so that the requirement of a user on stereo sound effect can be effectively guaranteed, and the condition that the stereo sound effect cannot be generated due to the fact that the mobile terminal controls the loudspeakers to be closed by mistake is generated.

In this embodiment, the audio types may be divided according to application scenarios, wherein the audio types may include: the voice communication system comprises a multimedia type, an alert tone type, a communication voice type and the like, wherein the multimedia type audio can comprise music, video, game audio and the like, the alert tone type audio can comprise a telephone alert tone, an application alert tone, a short message alert tone and the like, and the communication voice type audio can comprise voice of a communication scene such as a digital communication and a network communication.

Step S250: and when the current scene is a scene in which the mobile terminal needs stereo sound effect, controlling the at least two loudspeakers to work simultaneously and reducing the volume of the at least one loudspeaker.

In the embodiment of the application, when the mobile terminal determines that the mobile terminal is in a scene requiring the stereo sound effect, the mobile terminal can control at least two speakers to work simultaneously in order to ensure the normal stereo sound effect, but because the current power consumption of the mobile terminal is higher, the output power of the speakers can be reduced in a mode of reducing the volume of the speakers, and then the power consumption of the speakers is reduced. Wherein the mobile terminal may decrease the volume of one or more speakers.

In some embodiments, the mobile terminal determining that the mobile terminal is in a scene requiring a stereo sound effect, and reducing the volume of the at least one speaker may include: acquiring a first distance between the left ear of a user and the mobile terminal and a second distance between the right ear of the user and the mobile terminal; if the first distance is smaller than the second distance, reducing the volume of a loudspeaker used for providing left channel sound effect in at least two loudspeakers; and if the first distance is larger than the second distance, reducing the volume of the loudspeaker for providing the sound effect of the right channel in the at least two loudspeakers.

In this embodiment, because the stereo sound effect is obtained by fusing the sounds of different channels after being transmitted into the corresponding ears, the user can feel the stereo sound effect, and therefore, the mobile terminal can adjust the volume of the speaker of the left channel sound effect down without changing the volume of the speaker of the right channel sound effect if the left ear is closer to the mobile terminal by determining the distance between the two ears of the user, so that the volumes of the sounds of the two channels actually perceived by the user are substantially the same, and the power consumption brought by the speaker is reduced while the requirement of the stereo sound effect of the user is met. In some modes, the mobile terminal may acquire a depth image of a face of the user through the depth camera, and determine distances from the left ear and the right ear of the user to the mobile terminal respectively according to the depth image, and of course, the distances from the left ear and the right ear of the user to the mobile terminal may also be acquired in other modes, which is not limited herein.

In some embodiments, the mobile terminal determining that the mobile terminal is in a scene requiring a stereo sound effect, and reducing the volume of the at least one speaker may include: acquiring the distance between the left ear of the user and each loudspeaker and the distance between the right ear of the user and each loudspeaker; determining a first loudspeaker which is closest to the left ear in the at least two loudspeakers according to the distance of the left ear relative to each loudspeaker; determining a second loudspeaker closest to the right ear in the at least two loudspeakers according to the distance of the right ear relative to each loudspeaker; and reducing the volume of the other loudspeakers except the first loudspeaker and the second loudspeaker in the at least two loudspeakers.

In some modes, the mobile terminal can acquire a depth image of a face of a user through the depth camera, determine distances from a left ear and a right ear of the user to the depth camera of the mobile terminal respectively according to the depth image, and then determine distances from the left ear and the right ear of the user to each speaker respectively according to a pre-stored spatial position relationship (relative position, distance and the like) between the depth camera and each speaker by the mobile terminal. Different from the previous embodiment, when the number of the speakers of the mobile terminal is more than two, the mobile terminal may select two speakers to be respectively used as the speaker for the left channel sound effect and the speaker for the right channel, and the selected volume of the first speaker and the second speaker is not changed according to the distance between each ear and the speaker, and the other speakers except the two speakers may perform corresponding volume reduction, so as to better satisfy the requirement of the user for the stereo sound effect and reduce the power consumption brought by the speakers.

The control method of the loudspeaker provided by the embodiment of the application has the advantages that when the power consumption of the mobile terminal is larger than the specified power consumption, according to the difference of the demands of the scene where the mobile terminal is located on the stereo sound effect, when the current scene is the scene needing the stereo sound effect, only the volume of the loudspeaker is reduced, when the current scene is the scene needing the stereo sound effect, at least one loudspeaker is closed, so that under the scenes with the different demands on the stereo sound effect, the sound output by the loudspeaker of the mobile terminal can be matched with the scene, the demands of the scene on the stereo sound effect are met, the demands of a user on the audio playing effect are met, the power consumption of the mobile terminal is effectively reduced, the situation that the power consumption of the mobile terminal is large is avoided, and the cruising ability of the mobile terminal is improved.

Referring to fig. 4, fig. 4 is a flowchart illustrating a method for controlling a speaker according to another embodiment of the present application. The method for controlling the speaker is applied to the mobile terminal, and will be described in detail with respect to the flow shown in fig. 4, and the method for controlling the speaker may specifically include the following steps:

step S310: and when the mobile terminal plays audio through the loudspeaker, detecting the power consumption of the mobile terminal.

Step S320: and when the power consumption of the mobile terminal is larger than the specified power consumption, acquiring scene data through the sensor.

In the embodiment of the present application, step S310 and step S320 may refer to the contents of the foregoing embodiments, and are not described herein again.

Step S330: and determining the current scene of the mobile terminal according to the scene data, wherein different scenes have different requirements on the stereo sound effect.

In the embodiment of the present application, the scene in which the mobile terminal is located may be divided according to the degree of reduction of sound energy, that is, the amount of influence on the volume effect of sound, in addition to the difference in the stereo sound effect. That is, the mobile terminal may determine, according to the scene data, that the current scene is a scene requiring a stereo sound effect or a scene not requiring a stereo sound effect, and may also determine that the current scene is a scene divided according to an influence amount on a volume effect of sound. When the mobile terminal is in different divided scenes and the loudspeaker outputs sound with the same output power, the sound volume effect actually felt by the user is different. Therefore, after the mobile terminal determines the scene where the mobile terminal is located, if the power consumption brought by the loudspeaker needs to be reduced, the output power of the loudspeaker can be controlled according to the influence of different scenes on sound propagation. For example, the scene may be an indoor scene, an outdoor scene, etc.; for another example, the scene may be a scene corresponding to environmental noise of different intensity levels, or the like.

In some embodiments, the scene in which the mobile terminal is located may be divided into an indoor scene and an outdoor scene, and it can be understood that, under the condition that the speakers are at the same output power, the loudness that the user can feel when the mobile terminal is located in the indoor scene to play audio is generally better than the loudness that the user can feel when the mobile terminal is located in the indoor scene to play audio. Thus, by dividing the scenes in this way, the output power of the speakers can be adjusted for different scenes. In this embodiment, the mobile terminal may determine that the mobile terminal is in an indoor environment or in an outdoor environment through ambient brightness, a location of GPS positioning, and the like.

Step S340: and determining that the current scene is the scene of the non-required stereo sound effect.

Step S350: and when the current scene is an indoor scene, closing at least one loudspeaker of the at least two loudspeakers, and simultaneously reducing the volume of at least one loudspeaker in the working state.

Step S360: and when the current scene is an outdoor scene, at least one loudspeaker in the at least two loudspeakers is closed.

In the embodiment of the application, because the sound volume effect of the mobile terminal is lower than that of an indoor scene when the mobile terminal is in an outdoor scene, when the current scene is a scene with no requirement on stereo sound effect, if the current scene is an indoor scene, at least one loudspeaker in at least two loudspeakers can be closed, and the volume of at least one loudspeaker in the loudspeakers in a working state is reduced, so that the power consumption of the loudspeakers is reduced; and if the current scene is an outdoor scene, at least one of the at least two speakers may be turned off. Therefore, the output power reduced by the loudspeaker when the mobile terminal is in an indoor scene can be larger than the output power reduced by the loudspeaker when the mobile terminal is in an outdoor scene, the power consumption of the loudspeaker can be reduced, the sound output by the loudspeaker can be matched with the scene, the power consumption of the loudspeaker can be reduced as much as possible, and the phenomenon that the sound output by the loudspeaker cannot adapt to the scene and a user cannot hear the sound after the output power is reduced is avoided.

Further, considering that turning off the speakers may have an effect on sound playing, the effect will be amplified when the mobile terminal is in an outdoor scene, and therefore, in the outdoor scene, it may be to turn off at least one speaker and raise the volume of at least one speaker in an operating state. For example, the mobile terminal includes a main speaker and a sub-speaker, which may be turned off and the volume of the main speaker raised during an outdoor scene.

Step S370: and determining that the current scene is a scene in which the mobile terminal is in need of stereo sound effect.

Step S380: and when the current scene is an indoor scene, controlling the at least two loudspeakers to work simultaneously and reducing the volume of the at least one loudspeaker.

Step S390: and when the current scene is an outdoor scene, controlling the at least two loudspeakers to work simultaneously.

In the embodiment of the application, when the current scene is a scene requiring the stereo sound effect, because the sound volume effect is lower than that of an indoor scene when the mobile terminal is in an outdoor scene, if the current scene is an indoor scene, because the stereo sound effect needs to be ensured, the simultaneous working of at least two loudspeakers can be controlled, and the volume of at least one loudspeaker is reduced; and if the current scene is an outdoor scene, the at least two loudspeakers can be controlled to work simultaneously without reducing the volume of the loudspeakers, so that the receiving of the sound by the user is not influenced. Therefore, the output power reduced by the loudspeaker when the mobile terminal is in an indoor scene can be larger than the output power reduced by the loudspeaker when the mobile terminal is in an outdoor scene, the power consumption of the loudspeaker can be reduced, the sound output by the loudspeaker can be matched with the scene, and the phenomenon that the sound output by the loudspeaker cannot adapt to the scene and a user cannot hear the sound clearly after the output power is reduced is avoided.

According to the control method of the loudspeaker, when the power consumption of the mobile terminal is larger than the specified power consumption, according to different requirements of a scene where the mobile terminal is located on the stereo sound effect, when the current scene is the scene requiring the stereo sound effect, only the volume of the loudspeaker is reduced, and when the current scene is the scene not requiring the stereo sound effect, at least one loudspeaker is closed. And when controlling the loudspeaker, still consider the influence of indoor scene and outdoor scene to the sound propagation, further control to indoor and outdoor scene for the sound of speaker output can match with the scene, satisfy the demand of user to the stereo effect, also avoid reducing output power after, the sound of speaker output can't adapt to the scene, and make the phenomenon that the user can't hear the sound take place, also effectual reduction mobile terminal's consumption, avoid the great condition of mobile terminal's consumption to take place constantly, and then promoted mobile terminal's duration.

Referring to fig. 5, fig. 5 is a flowchart illustrating a method for controlling a speaker according to still another embodiment of the present application. The method for controlling the speaker is applied to the mobile terminal, and will be described in detail with respect to the flow shown in fig. 5, and the method for controlling the speaker may specifically include the following steps:

step S410: and when the mobile terminal plays audio through the loudspeaker, detecting the power consumption of the mobile terminal.

Step S420: and when the power consumption of the mobile terminal is larger than the specified power consumption, acquiring scene data through the sensor.

In the embodiment of the present application, step S410 and step S420 may refer to the contents of the foregoing embodiments, and are not described herein again.

Step S430: and determining the current scene of the mobile terminal according to the scene data, wherein different scenes have different requirements on the stereo sound effect.

In the embodiment of the application, the scene where the mobile terminal is located may also be divided into a target scene of weak environmental noise and a scene of other strong environmental noise. If the volume of the environmental noise is greater than the preset volume, determining the scene of the environmental noise as weak; if the volume of the environmental noise is less than or equal to the preset volume, the scene of the environmental noise with other intensity can be determined. The specific magnitude of the preset volume may not be limited, and may be, for example, 40 db, or 45 db. It can be understood that, under the condition that the loudspeakers are at the same output power, the loudness that the user can feel when the mobile terminal plays the audio in the scene with weak environmental noise is generally better than the loudness that the user can feel when the mobile terminal plays the audio in the scene with strong environmental noise. Therefore, by dividing the scenes, the output power of the speaker can be adjusted for different scenes.

Step S440: and when the current scene is a scene without the requirement of stereo sound effect and the current scene is a target scene, closing at least one loudspeaker of the at least two loudspeakers and reducing the volume of at least one loudspeaker in the loudspeakers in a working state, wherein the volume of the environmental noise of the target scene is lower than that of a preset volume scene.

In the embodiment of the application, because the sound volume effect of the mobile terminal in the environment with weak environmental noise is higher than the sound volume effect of the mobile terminal in the environment with other environmental noise with strong intensity, when the current scene is a scene without a stereo sound effect and is a target scene, the mobile terminal can turn off at least one speaker of the at least two speakers and simultaneously reduce the volume of at least one speaker of the speakers in a working state; when the current scene is a scene of the non-required stereo sound effect and the current scene is not a target scene, only at least one speaker of the at least two speakers may be turned off. Therefore, the power consumption of the loudspeaker can be reduced, the sound output by the loudspeaker can be matched with a scene, the power consumption of the loudspeaker can be reduced as much as possible, and the phenomenon that the sound output by the loudspeaker cannot adapt to the scene and a user cannot hear the sound after the output power is reduced is avoided.

Step S450: and when the current scene is a scene in which the mobile terminal is in need of stereo sound effect and the current scene is the target scene, controlling the at least two loudspeakers to work simultaneously and reducing the volume of the at least one loudspeaker.

Because the sound volume effect of the mobile terminal in the environment with weak environmental noise is higher than the sound volume effect of the mobile terminal in the environment with other environmental noise with strong intensity, when the current scene is a scene requiring stereo sound effect and the current scene is a target scene, the stereo sound effect is required to be ensured, the sound volume of at least one loudspeaker can be reduced while at least two loudspeakers are controlled to work simultaneously; when the current scene is a scene requiring stereo sound effect and is not a target scene, the at least two loudspeakers can be controlled to work simultaneously without reducing the volume of the loudspeakers. Therefore, the power consumption of the loudspeaker can be reduced, the sound output by the loudspeaker can be matched with a scene, the requirement of a user on the stereo sound effect is met, the power consumption of the loudspeaker can be reduced as much as possible, and the phenomenon that the sound output by the loudspeaker cannot adapt to the scene and the user cannot hear the sound clearly after the output power is reduced is avoided.

In some embodiments, an indoor scene, an outdoor scene, and a target scene may also be combined, that is, when adjusting the output power of the speaker, both the indoor or outdoor situation and the actual ambient noise may be considered.

Specifically, when the current scene is a scene requiring stereo sound effect, if the mobile terminal is in an indoor scene and a target scene, the volume of the first number of speakers may be reduced while controlling the operation of at least two speakers, and if the mobile terminal is in the indoor scene but not in the target scene, the volume of the second number of speakers may be reduced, where the first number is greater than the second number; when the current scene is a scene requiring stereo sound effects, if the mobile terminal is not in an indoor scene but in a target scene, the volume of the speakers of the third number can be reduced while controlling the at least two speakers to work, and if the mobile terminal is neither in the indoor scene nor in the target scene, the volume of the speakers of the fourth number can be reduced, wherein the third number is greater than the second number, and the fourth number is greater than the third number.

Specifically, when the current scene is a scene that does not require stereo sound effect, if the mobile terminal is in an indoor scene and a target scene, the volume of the fifth number of speakers may be reduced while at least one speaker is turned off, and if the mobile terminal is in the indoor scene but not in the target scene, the volume of the sixth number of speakers may be reduced, where the fifth number is greater than the sixth number; when the current scene is a scene requiring stereo sound effects, if the mobile terminal is not in an indoor scene but in a target scene, the volume of the seventh number of speakers may be reduced while at least one speaker is turned off, and if the mobile terminal is neither in the indoor scene nor in the target scene, the volume of the eighth number of speakers may be reduced, where the seventh number is greater than the sixth number, and the eighth number is greater than the seventh number.

Of course, in the above manner, the power consumption of the speaker in different scenes may be controlled by adjusting the volume to different degrees.

According to the loudspeaker control method provided by the embodiment of the application, when the power consumption of the mobile terminal is larger than the specified power consumption, according to different requirements of a scene where the mobile terminal is located on the stereo sound effect, when the current scene is the scene requiring the stereo sound effect, only the volume of the loudspeaker is reduced, and when the current scene is the scene not requiring the stereo sound effect, at least one loudspeaker is closed. And when controlling the loudspeaker, still consider the influence of environmental noise to sound propagation, further control to the target scene of weak environmental noise, further reduce the consumption of loudspeaker, make the sound of loudspeaker output can match with the scene, satisfy the demand of user to the stereo effect, also avoid reducing output power after, the sound of loudspeaker output can't adapt to the scene, and the phenomenon that makes the user can't hear the sound clearly takes place, also effectual the consumption of mobile terminal has been reduced, avoid the great condition of consumption of mobile terminal to take place continuously, and then promoted the duration of the mobile terminal.
