Brief description of the drawings
, below will be to embodiment or existing in order to illustrate more clearly of the embodiment of the present application or technical scheme of the prior art
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
The embodiment of application, for those of ordinary skill in the art, on the premise of not paying creative work, can also basis
The accompanying drawing of offer obtains other accompanying drawings.
A kind of flow chart of the method for calibration microphone that Fig. 1 is provided by the embodiment of the present application；
A kind of structural representation of the system for calibration microphone that Fig. 2 is provided by the embodiment of the present application.
Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present application clearer, below in conjunction with the embodiment of the present application
In accompanying drawing, the technical scheme in the embodiment of the present application is clearly and completely described, it is clear that described embodiment is
Some embodiments of the present application, rather than whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belong to the scope of the application protection.
It refer to Fig. 1, a kind of flow chart of the method for calibration microphone that Fig. 1 is provided by the embodiment of the present application, specifically
Scheme is as follows：
S1：When receiving calibration command, setting sentence is presented on a display screen for reading aloud；
Receiving calibration command means that user will calibrate to microphone, and its concrete form is not limited at this
It is fixed, can send to instruct by bluetooth, or by Voice command, such as user say " calibration microphone " start afterwards into
Row calibration, can also there is other forms.
During calibration, setting sentence is presented on a display screen for reading aloud, display screen here can be times of user at one's side
One display screen.Such as on by bluetooth connection, it can be shown in the terminal (mobile phone or tablet personal computer) of user, Huo Zhezhi
It is connected on display screen display of automatic navigator etc..
So-called setting sentence can be any sentence pre-set, preferably have here with practical application scene certainly
The helpful tips sentence of pass.For example traffic safety warm tip term etc. is shown on automatic navigator.
It is noted that can select directly to carry out the calibration function when first using microphone, or first carry out
Functional test is so that user voluntarily judges whether to need calibration etc..
S2：Recorded when user reads aloud the setting sentence, obtain recording data；
User referred herein refers to the people of all adjustable microphones, is not only to refer to the user used.It is but logical
Often for mobile unit, for being driver.
Certainly, this step acquiescence is carried out under a relatively quiet environment, carries out microphone in a noisy environment
Calibrate meaningless.
When reading aloud, user should be read aloud with normal word speed and volume.
S3：Judge the recording data whether in given threshold；If it is not, into S4；If so, then enter S5；
After recording data is obtained, the recording data is detected.The content of detection generally includes to detect the sound of sound
Matter, volume etc., noise reduction process of sound etc. can also be included.The decibel data in recording data can be obtained, then are judged
Whether decibel data are in given threshold.The setting of threshold value should be by those skilled in the art according to experimental result or actual conditions
Set, be not construed as limiting herein accordingly.
Further, when detecting decibel, if being more than given threshold, it is believed that data distortion, can now turn down microphone
Gain parameter；If being less than given threshold, now data waveform and voice-controlled software are not enough to analyze data, can cause other side during call
Hear that wave volume is smaller, therefore the gain parameter of microphone can be heightened.
Certainly other corresponding corrections of recording data can also be related to, differ a citing herein.
Certainly, if recording data is in the range of given threshold, this correction can directly be terminated, and preserve current microphone
Parameter.
S4：The microphone parameters are calibrated, and return to S2；
S5：Terminate correction.
Because once correction be able to might not be set intact, S2 can be repeated to this step repeatedly to be corrected, carried
The success rate of height correction.It is contemplated that Consumer's Experience, can also set a maximum correction number.
The embodiment of the present application provides a kind of method for calibrating microphone, can realize that user reads aloud finger by the above method
After fixed sentence, parameter is calibrated automatically, can so be adapted to different microphone positions, and adapts to specify user's
Sound size.Software is finely adjusted without for specific use environment when developing relative program, reduces exploitation
Difficulty, shorten the construction cycle.
Based on above-described embodiment, as preferred embodiment, the recording data pair of the given threshold can also will be met
The canonical parameter when microphone parameters answered are set to start every time.Make in the microphone relevant parameter for obtaining meeting given threshold
Default standard parameter during every time to start in the future, repeat to calibrate when without user every time starting.Especially for vehicle mounted guidance
For instrument, the driver of a usual car is often the same user, and it is many convenient so to be brought for user.
