Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the present invention can be wanted by right
The multitude of different ways limited and cover is asked to implement.
Fig. 1 represents the broad flow diagram of the noise-reduction method described in the embodiment of the present invention.
Shown in Figure 1, this noise-reduction method can comprise the steps:
S101: judge whether ambient noise is more than predetermined threshold, and obtain a judged result；
S103: when described judged result is described ambient noise more than or equal to described predetermined threshold, open
The noise reduction algorithm opening described dual microphone carries out noise reduction；
S105: when described judged result is described ambient noise less than described predetermined threshold, close institute
State noise reduction algorithm.
In the technique scheme of the present embodiment, in step S101, before call, system needs detection mobile
Terminal open incoming call or remove Electricity Functional, that is system once detect mobile terminal open incoming call or remove electric work
Can, just automatically turning on the secondary microphone of mobile terminal, this pair microphone is used for collecting ambient noise, i.e. to making
Noise size around user is collected and judges.And system pre-sets a predetermined threshold, this makes a reservation for
Threshold value sets as the case may be, such as, can be 60 decibels, but be not limited to this, set this threshold value main
For deciding whether unlatching dual microphone noise reduction algorithm.
Step S103 is the judged result according to step S101 carries out concrete noise reduction execution, user
When ambient noise around is more than or equal to the threshold value set, open the noise reduction algorithm of the dual microphone of mobile terminal
Carry out noise reduction process, and in step S105, when the ambient noise that result is user judged is less than this threshold
During value, then close the noise reduction algorithm of dual microphone, and further close secondary microphone, open main Mike
Wind, and the most main microphone is operated.
By the technique scheme of the present embodiment, it is judged that the ambient noise around the front user of call, decision is
No unlatching dual microphone decrease of noise functions, thus how avoid the ambient noise around no matter user, the most automatically open
Open dual microphone decrease of noise functions, and the noise reduction algorithm brought has certain damage to call tone quality, easily cause
The slight distortion problem of sound.Further, according to circumstances determine whether to open dual microphone decrease of noise functions, also exempt from
Go artificial switching, improve the experience of user.
Preferably, when ambient noise is more than or equal to the threshold value set, the dual microphone of mobile terminal is opened
Noise reduction algorithm, and send to user and automatically turn on described dual microphone and carry out the prompting message of noise reduction.
Fig. 2 represents the particular flow sheet of the noise-reduction method described in the embodiment of the present invention.
Shown in Figure 2, noise-reduction method specifically can comprise the steps:
Step 20: send a telegram here or remove electricity；
I.e. this method need to be carried out when system detects mobile terminal incoming call or removes electricity.
Step 21: open secondary microphone；
When system detects mobile terminal incoming call or removes electricity, it is first turned on the secondary wheat of mobile terminal dual microphone
Gram wind, first this pair microphone collects the ambient noise around user.
Step 22: judge ambient noise size；
The ambient noise collected in step 21 is judged, it is judged that whether this ambient noise is more than default
Threshold value, in the present embodiment, the threshold value preset is as a example by 60dBA, in ambient noise more than or equal to 60dBA
Time, perform step 24, when this ambient noise is less than 60dBA, perform step 23.
Step 23: close noise reduction algorithm；
I.e. when ambient noise is less than 60dBA, close the noise reduction algorithm of dual microphone, this is because, fall
Algorithm of making an uproar has certain damage to call tone quality, easily causes the slight distortion of sound.Therefore, make an uproar at environment
When sound is less than 60dBA, close the noise reduction algorithm of dual microphone, to avoid because noise reduction algorithm is to call tone quality
Some damages.
Step 24: start noise reduction algorithm；
I.e. when ambient noise is more than or equal to 60dBA, start the noise reduction algorithm of dual microphone, to reduce ring
The impact on call of the border noise.
Step 25: close secondary microphone；
After closing the noise reduction algorithm of dual microphone, close secondary microphone.
Step 26: after starting the noise reduction algorithm of dual microphone, arrange noise reduction algorithm, for starting call
Prepare.
Step 27: open main microphone；
After closing secondary microphone, open main microphone, only use main microphone to be operated.
Step 28: complete Initialize installation, converses ready.
Dual microphone decrease of noise functions or closedown is automatically turned in this embodiment according to the ambient noise around user.
Efficiently solve prior art exists dual microphone noise reduction algorithm need the most manually to arrange and
The awkward problem brought.
Fig. 3 represents the structural representation of the denoising device described in the embodiment of the present invention.
Shown in Figure 3, denoising device, for having the mobile terminal of dual microphone, specifically comprise the steps that
Judge module 30, judges before being used for conversing whether ambient noise is more than predetermined threshold, and obtains a judgement
Result；Opening module 32, is that described ambient noise is more than or equal to described pre-for described judged result
When determining threshold value, the noise reduction algorithm opening described dual microphone carries out noise reduction；Close module 34, in institute
State judged result when being described ambient noise less than described predetermined threshold, close described noise reduction algorithm.
Preferably, described denoising device also includes: sending module (not shown), for sending to user
Automatically turn on described dual microphone and carry out the prompting message of noise reduction.
Preferably, described denoising device also includes: control module (not shown), is used for controlling described pair
The main microphone of microphone opens and controls the secondary microphone cut out of described dual microphone.
Preferably, described predetermined threshold is 60 decibels.
Mobile terminal includes above-mentioned denoising device.
The present invention, by judging the ambient noise around the front user of call, decides whether to open dual microphone noise reduction
Function, thus how avoid the ambient noise around no matter user, all automatically turn on dual microphone decrease of noise functions,
And the noise reduction algorithm brought has certain damage to call tone quality, easily cause the slight distortion problem of sound,
Meanwhile, dual microphone decrease of noise functions or closedown are automatically turned on according to the ambient noise around front user.Efficient solution
Prior art of having determined exists dual microphone noise reduction algorithm need the most manually to arrange and bring
Awkward problem.
The above is the preferred embodiment of the present invention, it is noted that for the common skill of the art
