Step 403: receiving the correction voice signal for the microphone acquisition that wireless headset is sent.
Wherein, the correction sound that the purpose of this step can acquire to receive the microphone for the preset quantity that wireless headset is sent
Sound signal.
Step 404: the frequency response in the correction voice signal of microphone acquisition being corrected, the microphone of preset quantity is made
There is default corresponding relationship and in corresponding default normal range (NR) in the frequency response in the correction voice signal of acquisition, obtain
Corresponding correction signal；Wherein, it is corresponding with the setting position of loudspeaker to preset corresponding relationship.
It is understood that being carried out in this step to the frequency response in the correction voice signal of the microphone acquisition of preset quantity
After correction, the default corresponding relationship between frequency response in the correction voice signal of the microphone acquisition of preset quantity is corresponded to respective
Default normal range (NR), can be by designer according to practical scene and user demand self-setting, can be according to preset quantity
The corresponding loudspeaker of microphone setting position correspondence be configured, as preset quantity be 2 when, if loudspeaker setting placing
Position on the perpendicular bisector of two microphones of the wireless headset of default placement location, then presetting corresponding relationship can be phase
Deng the microphone acquisition of, preset quantity correction voice signal in the corresponding default normal range (NR) of frequency response it is identical, i.e. this step
It can be corrected for the frequency response in the correction voice signal that acquire to microphone, the correction sound for acquiring two microphones is believed
Frequency response in number is equal and in default normal range (NR).
It should be noted that the purpose of this step can be for by the correction voice signal acquired to each microphone
Frequency response is compared with corresponding default normal range (NR), to the frequency in the correction voice signal of the microphone acquisition of preset quantity
Sound is corrected, and the frequency response in the correction voice signal for acquiring the microphone of preset quantity has default corresponding relationship and exists
In corresponding default normal range (NR).With preset quantity be 2 and loudspeaker is arranged in and is placed on the wireless of default placement location
For position on the perpendicular bisector of two microphones of earphone, it is shown that originally steps are as follows, comprising:
Step 501: judging the frequency response in the correction voice signal of each microphone acquisition whether in default normal range (NR)
It is interior；If it is not, then entering step 502.
It is understood that for the frequency response in the correction voice signal of microphone each in this step acquisition default
Situation in normal range (NR), can be in the frequency response difference in the correction voice signal of two microphone acquisitions, with any Mike
On the basis of frequency response in the correction voice signal of elegance collection, the frequency response corrected in voice signal that another microphone is acquired is corrected
It is identical to the frequency response in the correction voice signal acquired with the microphone, as shown in figure 5, when two microphones are main Mike respectively
When wind and auxiliary microphone, the frequency response in correction voice signal that auxiliary microphone can be acquired is corrected to the school with main Mike acquisition
Frequency response in positive voice signal is identical, and obtains corresponding rectification building-out value.
Step 502: then judging whether there is the frequency response in the correction voice signal of any microphone acquisition default normal
In range；If so, entering step 503；If it is not, then entering step 504.
Step 503: the frequency response not in the correction voice signal of the microphone acquisition in default normal range (NR) is corrected to
It is identical as the frequency response in the correction voice signal of the microphone acquisition in default normal range (NR), and obtain corresponding rectification building-out
Value.
Step 504: the frequency response in the correction voice signal of two microphones acquisition being corrected to default frequency response, and is obtained
Corresponding rectification building-out value；Wherein, frequency response is preset in default normal range (NR).
That is, as shown in figure 5, being 2 with preset quantity and loudspeaker is arranged in and is placed on the nothing of default placement location
For position on the perpendicular bisector of two microphones of line earphone, whether step 404 may determine that two microphone frequency responses pre-
If in normal range (NR): 1, two microphone frequency responses are all being preset in normal range (NR), the school that charging box acquires auxiliary microphone
Frequency response in positive voice signal is corrected to identical with main microphon, and obtains corresponding correction signal；2, only one microphone
In default normal range (NR), storage box will be in the correction voice signal that the microphone in default normal range (NR) acquires
Frequency response is corrected to identical as another microphone, and obtains corresponding correction signal；3, the correction sound letter of two microphone acquisitions
Not in default normal range (NR), charging box can believe the correction sound of two microphone frequency response acquisitions for frequency response in number
Frequency response in number is corrected to the default frequency response (such as the central value of default normal range (NR)) of default normal range (NR), and obtains corresponding school
Positive signal.
Step 405: correction signal being sent to wireless headset, is corrected with the frequency response to microphone.
It is understood that the particular content of the correction signal in this step, it can be by designer according to practical scene
, can be according to the corrected concrete mode of frequency response to microphone with user demand self-setting, correspondence is configured, such as nothing
The processor of line earphone is written to DSP (Digital Signal Processing, at digital signal by that will correct offset
Manage device) corresponding position, when being corrected to the frequency response of microphone, correction signal may include need it is corrected to frequency response
The corresponding rectification building-out value of microphone.As long as the processor of wireless headset can use correction signal and carry out to the frequency response of microphone
Correction, the present embodiment do not do any restrictions to this.
