The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.It is understood that
Specific embodiment described herein is used only for explaining the present invention, rather than limitation of the invention.Additionally
Also, it should be noted for the ease of describe, accompanying drawing illustrate only part related to the present invention rather than
Full content.
Embodiment one
A kind of method embodiments providing volume adjusting, it is adaptable to user uses mobile terminal to listen
Audio frequency and/or see video, due to the interference of background noise, user can not hear clearly audio sound and video sound,
In the case of needing volume is adjusted, as it is shown in figure 1, the volume adjusting that the embodiment of the present invention provides
Method include step S101-S104:
Step S101, volume of reception regulation signal.
In this step, run on the audio playing software on mobile terminal or video jukebox software starts to broadcast
When putting audio or video, the screen of mobile terminal can display whether regulate the icon of volume, volume is adjusted
Joint signal is to trigger the signal that this icon whether regulating volume produces.If receiving volume adjustment signals,
Then can represent that the volume of mobile terminal needs regulation.If not receiving volume adjusting letter in Preset Time
Number, then can represent that the volume of mobile terminal need not regulation.Triggering can be to click, double-click or slide
The operation of this volume adjusting icon.This mobile terminal may include that mobile phone, notebook computer and flat board electricity
Brains etc. can carry out listening audio frequency and/or seeing the device of video.Volume adjustment signals at least includes current default
Volume, current default volume can be the volume of current time mobile terminal, current time mobile terminal
Volume can be to listen audio frequency last time and/or saw the volume of video, it is also possible to is to listen audio frequency in last time and/or saw
The volume reset after video.
Step S102, according to volume adjustment signals sampling background audio, it is thus achieved that the volume of background audio.
In this step, mobile terminal has upstream tones device and downstream tones device, it is possible to use move
The upstream tones device of dynamic terminal gathers background audio, and upstream tones device can be built-in mike,
Downstream tones device can be receiver and speaker.Background audio can be the sound that mankind's activity sends,
Such as, speak sound and singing sound；Can also be the sound of nature, such as, sound of the wind, singing of the stream
And chirm.
Step S103, according to volume and the current default volume of background audio, calculates broadcast sound volume.
In this step, can be according to the volume of background audio, current default volume and default algorithm meter
Calculate and play consumption, listen audio frequency and the optimal auditory effect of viewing video, optionally, in advance realizing user
If algorithm can include but not limited to the K level weights accumulation algorithm of volume.Broadcast sound volume would generally be than the back of the body
Giving great volume of scape audio frequency, to cover the volume of background audio so that user can catch audio sound and
Video sound.
Step S104, is adjusted volume to broadcast sound volume by current default volume.
In this step, if current default volume is more than broadcast sound volume, then reduce volume to broadcast sound volume；
If current default volume is less than broadcast sound volume, then elevated volume is to broadcast sound volume.
By the method for volume adjusting a kind of disclosed in the embodiment of the present invention, volume adjusting can received
After signal, according to current default volume and the volume of background audio, calculate applicable user and listen audio frequency and see
The volume of video, and by the volume of mobile terminal by current default volume adjusting to be suitable for user listen audio frequency and
See the volume of video, to meet user's audition demand under different scenes.
Embodiment two
The method embodiments providing another kind of volume adjusting, such as Fig. 2, the embodiment of the present invention carries
The method of the volume adjusting of confession comprises the following steps S201-S209:
Step S201, receives playing audio signal.
In this step, playing audio signal may include that and plays the audio signal of video and play audio frequency
Audio signal in any one.When the audio software run on mobile terminal commences play out audio frequency
Time, the audio signal playing audio frequency can be received；Or, when row video software on mobile terminal
When commencing play out video, the audio signal playing video can be received.
Step S202, according to playing audio signal, displays whether to regulate the icon of volume, triggers icon
Then generate volume adjustment signals.
In this step, when receiving playing audio signal, on the interactive interface of mobile terminal, display is
The icon of no regulation volume, if triggering this icon representation volume volume less than background noise, needs regulation
Volume, then generate volume adjustment signals；If not triggering this icon in Preset Time, do not receive volume
Regulation signal then represents that the volume playing audio frequency is more than the volume of background noise, it is not necessary to regulation volume just may be used
To converse, to listen audio frequency and see video normally.
Step S203, volume of reception regulation signal.
In this step, volume adjustment signals at least includes current default volume.
Step S204, according to volume adjustment signals sampling background audio, it is thus achieved that the volume of background audio.
In this step, along with User Activity, mobile terminal place scene can change at any time, example
As total indoor scene is changed to Outdoor Scene.In order to obtain preferable auditory effect under different scenes, can
With according to volume adjustment signals, according to default periodic sampling background audio, it is thus achieved that the volume of background audio.
Owing to the electric quantity of power supply of mobile terminal is limited, for improving the cruising time of power supply, can sample with proper extension
The cycle of background audio.
Step S205, compares volume and the current default volume of background audio, if the volume of background audio
Less than current default volume, then can perform the operation of step S206；If the volume of background audio is more than
Equal to described current default volume, then perform the operation of step S207.
In this step, if the volume of background audio is less than current default volume, then can represent that user can
Normally to listen audio frequency or viewing video, volume can not be adjusted；If the volume of background audio is more than or equal to working as
Front default volume, then can represent that user can not hear clearly the sound of audio or video, needs to adjust volume.
Step S206, using current default volume as broadcast sound volume.
Step S207, according to volume and the current default volume of background audio, calculates broadcast sound volume.
Step S208, by volume by current default volume adjusting to broadcast sound volume.
In this step, for avoiding mobile terminal loudness to suddenly change, can by volume by current default volume gradually
Fade to broadcast sound volume.Such as, current default volume is 45 decibels, and broadcast sound volume is 78 decibels, then may be used
It is 46,47,48 so that volume is gradually increased by 45 decibels ... 78 decibels, to realize volume by currently
Default volume gradual change, to broadcast sound volume, prevents volume from increasing to suddenly 78 decibels of audition to user and causes
Damage.
Step S209, using broadcast sound volume as default volume.
In this step, after adjusting, broadcast sound volume is as default volume, when once carrying out volume tune upper
During joint, if consistent with the scene of this volume adjusting, such as, it be Outdoor Scene equally, then need not adjust
Joint volume, i.e. carries out listening audio frequency and seeing video with default volume, it is not necessary to carry out volume adjusting again.
The technical scheme provided by the present invention, can be after receiving volume adjustment signals, according to working as
Front default volume and the volume of background audio, calculate applicable user, listen audio frequency and see the volume of video, and
The volume of mobile terminal to being suitable for user by current default volume adjusting is listened audio frequency and is seen the volume of video,
To meet user's audition demand under different scenes.
