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) configured with the speaker control apparatus 400. The mobile terminal comprises a plurality of speakers and a sensor, wherein the sensors are used for collecting scene data of a scene where the mobile terminal is located, and the speakers are used for generating stereophonic sound effects when working together. The specific flow of the present embodiment will be described below by taking a mobile terminal as an example. The following will describe the flow chart shown in fig. 2 in detail, and the method for controlling the speaker specifically may include the following steps:
Step S110: and detecting the power consumption of the mobile terminal when the mobile terminal plays the audio through the loudspeaker.
In the embodiment of the application, the mobile terminal can detect the condition of playing the audio and determine whether to output the sound by the loudspeaker when detecting the condition of playing the audio. The mobile terminal can detect whether an application plays audio or not, or detect whether an audio decoder works or not, and determine whether the application plays audio or not. In some modes, when the mobile terminal detects that the mobile terminal is in the condition of audio playing, whether an external audio playing device (such as a wired earphone, a Bluetooth sound box and the like) is connected can be detected, if the mobile terminal is not connected with an external audio part device, the mobile terminal plays the audio by adopting a loudspeaker, so that the mobile terminal can be determined to play the audio through the loudspeaker currently; in other embodiments, the mobile terminal may also determine a current sound output mode (e.g., a headset mode, a play-out mode, etc.), and if the current sound output mode is the play-out mode, may determine that the mobile terminal is currently playing audio through a speaker.
In the embodiment of the application, when the mobile terminal plays the 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 brought by the loudspeaker can be reduced by adjusting the output power of the loudspeaker later.
In some embodiments, the mobile terminal may determine its current power consumption by detecting a power consumption condition, an internal temperature condition, a working condition of a sensor with larger power consumption, and the like. And the mobile terminal can detect whether the power consumption is greater than the specified power consumption, wherein the power consumption represents a situation that the power consumption of the mobile terminal is greater and the current power consumption needs to be reduced. As an implementation manner, the mobile terminal may count the power consumption in a specified period of time before the current time to determine the current power consumption of the mobile terminal, where the specified period of time may be 10 minutes, 20 minutes, and the like, which 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, where if the power consumption of the mobile terminal is larger than the specified power consumption, it may be determined that the current power consumption of the mobile terminal is larger. The specific value of the specified power consumption may not be limiting. As another embodiment, the mobile terminal may detect the temperature inside the mobile terminal, and the case that the temperature is greater than the specified temperature is regarded as the case that the power consumption is greater than the specified power consumption, that is, the case that the power consumption is greater, where the specific value of the specified temperature may not be limited, and may be 30 degrees, 35 degrees, and the like, for example. As a further implementation mode, the mobile terminal can detect the running application, determine the current power consumption according to the power consumption occupied by the application in the past running process, and compare the current power consumption with the appointed power consumption to determine whether the current power consumption of the mobile terminal is larger or not; as another implementation mode, the mobile terminal can determine the target application with the power consumption larger than the appointed power consumption in the running process according to the power consumption occupied by the application in the previous running process, and can determine whether the target application is in a running state when the mobile terminal determines whether the current power consumption is larger than the appointed power consumption each time, and can determine that the power consumption of the mobile terminal is larger than the appointed power consumption if the target application is in the running state. As still another embodiment, the mobile terminal may detect whether a sensor having a larger power consumption therein is operated, for example, may detect whether a GPS (global positioning system ) sensor is in an operating state, and if so, 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 designated power consumption, acquiring scene data through the sensor.
In some embodiments, when determining that the power consumption of the mobile terminal is greater than the specified power consumption, the mobile terminal may collect scene data through a sensor to determine a current scene and reduce the power of the speaker according to the current scene. The mobile terminal can control the sensor for collecting the scene data of the scene where the mobile terminal is located to work so as to collect the scene data of the scene where the mobile terminal is located, and the collected scene data is obtained from the sensor. Wherein the scene data is used for the mobile terminal to determine the scene in which it is located in order to control the operation of the speaker according to the scene in which it 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 on the stereo sound effect, namely, different scenes have different requirements on the stereo sound effect, so that the scene where the mobile terminal is located can be subsequently determined, the output power of the loudspeaker can be controlled according to the different scenes, the loudspeaker can meet the stereo sound effect of the scene, 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, where the scene data may reflect a requirement of a use state of the mobile terminal for stereo sound effects, so that a current scene in which the mobile terminal is located may be determined.
Of course, the scene data may also be used to represent the influence condition of the current scene on sound propagation, that is, the influence condition of different scenes on sound propagation is different, and the scene data may also include environmental sound of the scene where the mobile terminal is located, environmental brightness of the scene where the mobile terminal is located, location where the mobile terminal is located, etc., and the specific scene data may not be limited, for example, the scene data may also include air pressure, how many obstacles obstruct sound propagation, the size of the space where the scene data is located, etc.
Step S130: and determining the current scene of the mobile terminal according to the scene data, wherein the requirements of different scenes on the stereo sound effect are different.
In the embodiment of the application, after the mobile terminal acquires the scene data, the current scene of the mobile terminal can be determined according to the scene data, and the scenes can be divided according to different requirements of the stereo effect, so that the mobile terminal can determine the scenes with different requirements of the stereo effect according to the scene data. The mobile terminal can pre-store scenes with different requirements for the stereo sound effect, and can compare the scene data with the scene data corresponding to different scenes according to the scene data so as to determine the current scene of the mobile terminal. For example, the mobile terminal also stores the corresponding relation between different scenes and scene data, and the current scene of the mobile terminal can be determined by using the acquired scene data and the corresponding relation; for another example, a pre-trained scene recognition model is set in the mobile terminal, the scene recognition model is obtained by training a large amount of training data, the training data can include a plurality of scene data and scenes marked on each scene data, and the mobile terminal can input the acquired scene data into the scene recognition model, so that the current scene in which the mobile terminal is located is obtained.
Step S140: and according to the current scene, at least one loudspeaker of the at least two loudspeakers is turned off, and/or the volume of the at least one loudspeaker is reduced.
In some embodiments, because the requirements for stereo sound effects are different for different scenes, at least one of the at least two speakers may be turned off and/or the volume of the at least one speaker may be reduced based on the determined current scene. The mobile terminal can reduce the output power of the loudspeaker by different magnitudes according to different scenes according to different requirements of different scenes on stereo sound effects. For example, for scenes where stereo sound effects are not required, at least one speaker may be turned off, or at least one speaker may be turned off while the volume of the other speakers is reduced; for scenes where stereo sound effects are desired, the volume of at least one speaker may be reduced. Therefore, the sound output by the loudspeaker with the reduced output power can be suitable for the requirement of scenes on stereo sound effect, the requirement of users on the playing effect of audio is met, the power consumption brought 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 to continuously happen, and the cruising ability of the mobile terminal is further improved.
According to the control method of the loudspeaker, when the power consumption of the mobile terminal is larger than the designated power consumption, the loudspeaker is turned off and/or the volume of the loudspeaker is reduced according to different requirements of scenes where the mobile terminal is located on for stereo sound effects, so that the output sound of the loudspeaker of the mobile terminal can be matched with the scenes under the scenes with different requirements for stereo sound effects, the requirements of the scenes for the stereo sound effects are met, the requirements of users for the playing effects of the audio 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 further improved.
Referring to fig. 3, fig. 3 is a flow chart illustrating a method for controlling a speaker according to another embodiment of the 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, where the method for controlling the speaker specifically includes the following steps:
step S210: and detecting the power consumption of the mobile terminal when the mobile terminal plays the audio through the loudspeaker.
In the embodiment of the present application, step S210 may refer to the content of the foregoing embodiment, and is not described herein.
Step S220: and when the power consumption of the mobile terminal is larger than the designated power consumption, acquiring scene data through the sensor.
In the embodiment of the present application, when the mobile terminal detects that audio is played through a speaker, before executing steps S210 to S250, it may also 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 processes from step S210 to step S250 are executed, and if the mobile terminal is not in the preset control mode, the current flow 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, when the user does not want the mobile terminal to control the output power of the loudspeaker and wants to control the loudspeaker by the user, the preset control mode can be turned off; the user hopes that the mobile terminal controls the output power of the loudspeaker, so that the power consumption of the mobile terminal is saved, and the preset control mode can be selected to be started.
Step S230: and determining the current scene of the mobile terminal according to the scene data, wherein the requirements of different scenes on the stereo sound effect are different.
In some implementations, the scene data may 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 the current scene where the mobile terminal is positioned is a scene requiring stereo sound effect; 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 positioned is a scene with non-required stereo sound effect.
In this embodiment, if the mobile terminal is in a landscape screen arrangement state, that is, when the screen of the mobile terminal is in a landscape screen mode, the mobile terminal is generally a case of playing music, video, or game scenes, so that a user generally needs an effect of playing stereo; the mobile terminal is in a vertical screen placing state, namely when the screen of the mobile terminal is in a vertical screen mode, under the situation, the mobile terminal mostly outputs prompt audio, call audio and other conditions, so that when the mobile terminal is in a vertical screen playing state, stereo playing is mostly not needed. Therefore, according to the state of the mobile terminal in the horizontal screen arrangement state or the vertical screen arrangement state, whether the current scene is a scene requiring stereo sound effect can be determined. The mobile terminal may be provided therein with a gravity sensor. 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 positioned is a scene requiring stereo sound effect; 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 positioned is a scene with non-required stereo sound effect.
In this embodiment, when the mobile terminal is in a moving state, the mobile terminal is usually in a walking state, a running state or the like, and the user will not need to have stereo effect at this time, so when the mobile terminal is in a moving state, the current scene can be determined as the scene requiring stereo effect; otherwise, when the mobile terminal is in a motion state, the current scene where the mobile terminal is located can be determined to be a scene with non-required stereo sound effect. 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 of the mobile terminal in which the stereophonic sound effect is not required, closing at least one loudspeaker in the at least two loudspeakers.
In the embodiment of the application, after determining the current scene in which the mobile terminal is located, the mobile terminal can control at least two speakers according to the current scene. Specifically, when the current scene is a scene where the mobile terminal is in a non-required stereo sound effect, at least one speaker is turned off. Wherein, because the current scene does not need stereo sound effect, one or more speakers can be selected to be turned off, so as to reduce the power consumption brought by the speakers. In addition, in some scenarios, it may even be possible to keep only one speaker (e.g., the main speaker) operating, while the other speakers are selected to be turned off to further reduce power consumption.
In some embodiments, considering that the user may also need a stereo effect in some special cases, and the user needs the stereo effect is usually when playing multimedia audio, when the current scene is a scene that does not need the stereo effect, the mobile terminal may determine the audio type of the audio; performing a closing of at least one 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, at least two speakers are controlled to work simultaneously, and the volume of at least one speaker is reduced, so that the stereo effect required by a user can be effectively ensured, and the situation that the stereo effect cannot be generated due to the fact that the mobile terminal mistakenly controls the speakers to be closed can be effectively ensured.
In this embodiment, the audio types may be divided according to application scenes, wherein the audio types may include: the multimedia type, the prompting tone type, the conversation tone type and the like, the audio of the multimedia type can comprise music, video, game audio and the like, the audio of the prompting tone type can comprise telephone prompting tone, application prompting tone, short message prompting tone and the like, and the audio of the conversation tone type can comprise voice of conversation scenes such as digital conversation, network conversation and the like.
Step S250: and when the current scene is a scene of the mobile terminal in which the stereo sound effect is required, controlling the at least two speakers to work simultaneously, and reducing the volume of at least one speaker.
In the embodiment of the application, when the mobile terminal determines that the mobile terminal is in a scene requiring stereo sound effect, the mobile terminal can control at least two speakers to work simultaneously in order to ensure normal stereo sound effect, but the current power consumption of the mobile terminal is higher, so that the output power of the speakers can be reduced by reducing the volume of the speakers, and the power consumption of the speakers is further reduced. Wherein the mobile terminal may reduce the volume of one or more speakers.
In some embodiments, the mobile terminal determining that the active terminal is in a scenario requiring stereo sound effects, reducing the volume of 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 less than the second distance, reducing the volume of a speaker of the at least two speakers that is used to provide the left channel sound effect; if the first distance is greater than the second distance, the volume of the speaker of the at least two speakers that is to provide the right channel sound effect is reduced.
In this embodiment, since the stereo sound effects are fused after the sounds of different channels are transmitted into the corresponding ears, the user can feel the stereo sound effects, so that the mobile terminal can reduce the volume of the speaker of the left channel sound effect and the volume of the speaker of the right channel sound effect without changing by determining the distance between the two ears of the user and the mobile terminal, if the left ear is closer to the mobile terminal, so that the volumes of the sound effects of the two channels actually felt by the user are basically consistent, and the power consumption brought by the speaker is reduced while the requirement of the stereo sound effect of the user is met.

Referring to fig. 4, fig. 4 is a flow chart illustrating a method for controlling a speaker according to another embodiment of the 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, where the method for controlling the speaker specifically includes the following steps:
step S310: and detecting the power consumption of the mobile terminal when the mobile terminal plays the audio through the loudspeaker.
Step S320: and when the power consumption of the mobile terminal is larger than the designated power consumption, acquiring scene data through the sensor.
In the embodiment of the present application, the step S310 and the step S320 may refer to the content of the foregoing embodiment, and are not described herein.
Step S330: and determining the current scene of the mobile terminal according to the scene data, wherein the requirements of different scenes on the stereo sound effect are different.
In the embodiment of the application, the scene where the mobile terminal is located can be divided according to different stereo sound effects, and also can be divided according to the reduction degree of sound energy, namely, the influence quantity of the sound volume effect. That is, the mobile terminal may determine that the current scene is a scene requiring a stereo effect or a scene not requiring a stereo effect according to the scene data, and may also determine that the current scene is a scene divided according to an influence amount of the sound volume effect on the sound. When the mobile terminal is in different divided scenes, the volume effect actually felt by the user is different when the loudspeaker outputs sound with the same output power. Therefore, after determining the scene where the mobile terminal is located, if the power consumption of the loudspeaker needs to be reduced, the output power of the loudspeaker can be controlled according to the influence of different scenes on sound transmission. For example, the scene may be an indoor scene, an outdoor scene, or the like; for another example, the scene may be a scene corresponding to environmental noise of different intensity levels, or the like.
In some embodiments, the scenes in which the mobile terminal is located may be divided into an indoor scene and an outdoor scene, and it may be understood that, under the condition that the speakers are at the same output power, the loudness of sound that the user can feel when the mobile terminal is in the indoor scene to play audio is generally better than the loudness of sound that the user can feel when the mobile terminal is in the indoor scene to play audio. Therefore, by dividing the scenes, the output power of the speaker 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 GPS-located position, etc.
Step S340: and determining the current scene as the scene with the non-required stereo sound effect.
Step S350: when the current scene is an indoor scene, closing at least one of the at least two speakers, and simultaneously reducing the volume of at least one of the speakers in a working state.
Step S360: and when the current scene is an outdoor scene, at least one loudspeaker of the at least two loudspeakers is closed.
In the embodiment of the application, because the sound volume effect 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-demand stereo sound effect, if the current scene is an indoor scene, at least one of at least two speakers can be turned off, and the sound volume of at least one of the speakers in a working state is reduced, so that the power consumption of the speakers 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 after the output power is reduced is avoided, so that a user cannot hear the sound occurs.
Further, considering that the turning off of the speaker may have an effect on sound playing, when the mobile terminal is in an outdoor scene, the effect will be amplified, so that when in the outdoor scene, the at least one speaker may be turned off and the volume of the at least one speaker in an operating state may be raised. For example, the mobile terminal includes a main speaker and a sub speaker, and the sub speaker may be turned off and the volume of the main speaker may be increased when an outdoor scene.
Step S370: and determining the current scene as the scene of the mobile terminal in the requirement of stereo sound effect.
Step S380: and when the current scene is an indoor scene, controlling the at least two speakers to work simultaneously, and reducing the volume of at least one speaker.
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 stereo sound effect, the sound volume effect is lower than that of an indoor scene when the mobile terminal is in an outdoor scene, so that if the current scene is an indoor scene, at least two speakers can be controlled to work simultaneously and the sound volume of at least one speaker is reduced because the stereo sound effect is required to be ensured; and if the current scene is an outdoor scene, at least two loudspeakers can be controlled to work simultaneously without reducing the volume of the loudspeakers, so that the receiving of sound by a 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 after the output power is reduced and a user cannot hear the sound is avoided.
According to the control method of the loudspeaker, when the power consumption of the mobile terminal is larger than the designated power consumption, according to the different requirements of the scenes where the mobile terminal is located on the stereo effect, when the current scene is the scene requiring the stereo effect, the volume of the loudspeaker is only reduced, and when the current scene is the scene not requiring the stereo effect, at least one loudspeaker is closed. And when controlling the speaker, still consider indoor scene and outdoor scene to the influence of sound propagation, further control indoor and outdoor scene for speaker output's sound can match with the scene, satisfies the demand of user to stereophonic sound effect, also avoids reducing after the output, and the unable adaptation scene of speaker output's sound, and the phenomenon that makes the user can't hear sound takes place, also effectually reduced mobile terminal's consumption, avoided mobile terminal's the great circumstances of consumption to take place continually, 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, where the method for controlling the speaker specifically includes the following steps:
Step S410: and detecting the power consumption of the mobile terminal when the mobile terminal plays the audio through the loudspeaker.
Step S420: and when the power consumption of the mobile terminal is larger than the designated power consumption, acquiring scene data through the sensor.
In the embodiment of the present application, step S410 and step S420 may refer to the content of the foregoing embodiment, and are not described herein.
Step S430: and determining the current scene of the mobile terminal according to the scene data, wherein the requirements of different scenes on the stereo sound effect are different.
In the embodiment of the application, the scene where the mobile terminal is located can be divided into a target scene of weak environmental noise and a scene of environmental noise with other intensities. If the volume of the environmental noise is larger than the preset volume, a scene with weak environmental noise can be determined; if the volume of the environmental noise is less than or equal to the preset volume, a scene of the environmental noise of other intensities may be determined. The specific magnitude of the preset sound volume may not be limited, and may be, for example, 40 db, 45 db, or the like. It can be appreciated that, under the condition that the speakers are at the same output power, the loudness of sound that can be perceived by the user when the mobile terminal plays audio in a scene with weak environmental noise is generally better than the loudness of sound that can be perceived by the user when the mobile terminal plays audio in a scene with strong environmental noise. Therefore, the scenes are divided, and the output power of the loudspeaker can be adjusted for different scenes.
Step S440: and when the current scene is a scene with non-required stereo sound effect and the current scene is a target scene, closing at least one of the at least two speakers, and reducing the volume of at least one of the speakers in a working state, wherein the volume of the environmental noise of the target scene is lower than a scene with preset volume.
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 in the environment with other environmental noise, when the current scene is a scene with non-required stereo sound effect and the current scene is a target scene, the mobile terminal can turn off at least one of the at least two speakers and simultaneously reduce the sound volume of at least one of the speakers in a working state; when the current scene is a scene of non-desired stereo sound effect and the current scene is not a target scene, at least one speaker of the at least two speakers may be turned off only. 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 of the mobile terminal in which stereo sound effect is required and the current scene is the target scene, controlling the at least two speakers to work simultaneously, and reducing the volume of at least one speaker.
Because the sound volume effect of the mobile terminal in the environment with weak environmental noise is higher than the sound volume effect in the environment with environmental noise with other intensities, when the current scene is a scene requiring stereo sound effect and the current scene is a target scene, the stereo sound effect needs 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 the current scene is not a target scene, at least two speakers can be controlled to work simultaneously without reducing the volume of the speakers. Therefore, the power consumption of the loudspeaker can be reduced, the sound output by the loudspeaker can be matched with the scene, the requirement of a user on 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 after the output power is reduced, so that the user cannot hear the sound is avoided.
In some embodiments, the indoor scene, the outdoor scene, and the target scene may be combined, that is, when adjusting the output power of the speaker, both the indoor or outdoor situation and the actual environmental 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 a first number of speakers can be reduced while controlling at least two speakers to work, and if the mobile terminal is in an indoor scene but not in a target scene, the volume of a second number of speakers can be reduced, wherein the first number is greater than the second number; when the current scene is a scene requiring stereo sound effect, if the mobile terminal is not in an indoor scene but in a target scene, the volume of a third number of speakers can be reduced while controlling at least two speakers to work, and if the mobile terminal is not in an indoor scene or in a target scene, the volume of a fourth number of speakers can be reduced, wherein the third number is larger than the second number, and the fourth number is larger than the third number.
Specifically, when the current scene is a scene requiring no stereo sound effect, if the mobile terminal is in an indoor scene and a target scene, the volume of a fifth number of speakers may be reduced while at least one speaker is turned off, and if the mobile terminal is in an indoor scene but not in a target scene, the volume of a sixth number of speakers may be reduced, wherein the fifth number is greater than the sixth number; when the current scene is a scene requiring stereo sound effect, if the mobile terminal is not in an indoor scene but in a target scene, the volume of a seventh number of speakers may be reduced while at least one speaker is turned off, and if the mobile terminal is not in an indoor scene or in a target scene, the volume of an eighth number of speakers may be reduced, wherein 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 control of the power consumption of the speaker in different scenes can also be achieved by adjusting the volume of 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 designated power consumption, according to the different requirements of the scene where the mobile terminal is located on the stereo effect, when the current scene is the scene requiring the stereo effect, the volume of the loudspeaker is only reduced, and when the current scene is the scene not requiring the stereo 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 for the sound of speaker output can match with the scene, satisfies the demand of user to stereophonic sound effect, also avoids reducing after the output, and the unable adaptation scene of sound of speaker output, and the phenomenon emergence of messenger's user's unable sound of hearing, also effectually reduced the consumption of mobile terminal, avoided the great circumstances of consumption of mobile terminal to continuously take place, and then promoted mobile terminal's duration.
