Noise reduction unit, for carrying out noise reduction process according to noise reduction parameters.
Further, this device also comprises:
Setting unit, for arranging noise reduction parameters corresponding to noise reduction levels.
Further, this noise reduction unit specifically for:
Corresponding voice-frequency channel is loaded, the adaptive corresponding noise reduction algorithm with this grade noise reduction parameters inside voice-frequency channel according to noise reduction levels.
Further, this noise reduction unit specifically for:
Noise reduction parameters corresponding under noise reduction levels is write digital signal processor DSP, in real time according to default DSP noise reduction algorithm determination noise reduction.
Another object of the present invention is to provide a kind of mobile terminal, this mobile terminal comprises above-mentioned adjustable denoising device.
Adjustable noise-reduction method provided by the invention, device and mobile terminal, due to the noise reduction levels of input can be received, noise reduction parameters is upgraded according to noise reduction levels, then noise reduction process is carried out according to noise reduction parameters, reach the object that can regulate noise reduction, meet the different demands of user to noise processed.
Accompanying drawing explanation
Fig. 1 is the realization flow figure of adjustable noise-reduction method provided by the invention;
Fig. 2 is the function structure chart of adjustable denoising device provided by the invention.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and the embodiments, the present invention is further elaborated.Should be appreciated that embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, be the realization flow of a kind of adjustable noise-reduction method provided by the invention, details are as follows:
In step S101, receive the noise reduction levels of input.
It should be noted that, mobile terminal or adjustable denoising device comprise button, just can be received the noise reduction levels of input by button.
In step s 102, noise reduction parameters corresponding to noise reduction levels is upgraded according to noise reduction levels.
Wherein, noise reduction parameters and noise reduction levels are relations one to one, the noise reduction parameters that different noise reduction levels is corresponding different.
Before upgrading noise reduction parameters corresponding to noise reduction levels according to noise reduction levels, can also arrange the noise reduction parameters that noise reduction levels is corresponding, can be linear relationship between noise reduction levels and noise reduction parameters, also can be non-linear relation.
Wherein, the noise reduction parameters that specific implementation upgrades noise reduction levels corresponding according to noise reduction levels comprises two kinds of modes:
Mode one: load corresponding voice-frequency channel according to noise reduction levels, the adaptive corresponding noise reduction algorithm with this grade noise reduction parameters inside voice-frequency channel.
Mode two: noise reduction parameters corresponding under noise reduction levels is write digital signal processor DSP, in real time according to default DSP noise reduction algorithm determination noise reduction.
In step s 103, noise reduction process is carried out according to noise reduction parameters.
Such as a user uses mobile phone to call at concert scene, and in order to the atmosphere making the other side also experience concert scene, noise reduction levels is adjusted to minimum by this user, and telephone signal does not shield on-the-spot background effect.Such as another user is in supermarket again, and site environment is very noisy, in order to keep good communication effect with the other side, noise reduction levels being improved, effectively can shield on-the-spot noise, can reach good communication effect.
As shown in Figure 2, be the structure of a kind of adjustable denoising device provided by the invention, details are as follows:
The structure of this adjustable denoising device comprises receiving element 21, updating block 22 and noise reduction unit 23.
Receiving element 21, for receiving the noise reduction levels of input;
Updating block 22, for upgrading noise reduction parameters corresponding to noise reduction levels according to noise reduction levels;
Noise reduction unit 23, for carrying out noise reduction process according to noise reduction parameters.
This device can also comprise setting unit.
Noise reduction unit 23 specifically for: load corresponding voice-frequency channel according to noise reduction levels, the adaptive corresponding noise reduction algorithm with this grade noise reduction parameters inside voice-frequency channel.
Noise reduction unit 23 can also be specifically for: noise reduction parameters corresponding under noise reduction levels is write digital signal processor DSP, in real time according to default DSP algorithm determination noise reduction.
Another object of the present invention is to provide a kind of mobile terminal, this mobile terminal comprises above-mentioned adjustable denoising device.
In a word, adjustable noise-reduction method provided by the invention, device and mobile terminal, due to the noise reduction levels of input can be received, noise reduction parameters is upgraded according to noise reduction levels, then noise reduction process is carried out according to noise reduction parameters, reach the object that can regulate noise reduction, meet the different demands of user to noise processed.
