Between distance it is constant, turn next to Fig. 3.
In figure 3, the continuous perpendicular bisector between the first audio collection unit and the second audio collection unit represents electronics
The vertical plane of equipment placed side, in order to obtain first angle, it is necessary to rotate two collecting units, so that two collecting units obtain
Multigroup acoustic information, the position of the first sound source is determined according to multigroup acoustic information, so as to obtain first angle.
Assuming that the initial position of two audio collection units is the horizontal linear in Fig. 4, two audio collection units are revolved
The time circled is T, and the sample rate of two audio collection units is 6kHz, and the length of a frame sound is M.So, one is rotated
All collectable N frames voice data or N group voice datas, wherein, N=6000T/M.Due to the first audio collection unit and second

Individual is mirror image estimate and the angle γ of two audio collection unit line perpendicular bisectorsi2, γ is understood by geometrical relationshipi1+γi2=
180°.In addition, two audio collection units are when i-th group of data is gathered, the line and initial position of two collecting units
Angle be αi=i360 °/N, i=0~N-1.
By above-mentioned calculating, the angle β of the first sound source actual position and initial position can be obtainedi1With mirror position and initially
The angle β of positioni2,
βi1=αi+90°-γi1
βi2=αi+90°-γi2, formula 5
Wherein, i=0,1 ..., N-1.Calculate the angle and mirror-bit of each group of the first sound source actual position and initial position
Put the difference △ β between the angle of initial positioni, multigroup estimated location less than threshold value is done into average value, it is most average at last
It is worth the actual position of position sound.
By above-mentioned algorithm, calculate the position for obtaining the first sound source, so with regard to can obtain electronic equipment and the first sound source it
Between first angle, as shown in Figure 3.Specifically, in the embodiment of the present application, it is assumed that first angle is specially that the first audio is adopted

First angle is equal to the first predetermined angle, then the first judged result is yes；First predetermined angle is 30 °, and first angle is 15 °,
So first angle is less than the first predetermined angle, then the first judged result is yes.
When the first judged result when being, to show that first angle is less than or equal to the first predetermined angle, i.e. the first sound and
The angle of electronic equipment is smaller, then can determine the first voice data to intend collection voice data；When the first judged result is
When no, show that first angle is more than the first predetermined angle, i.e. the angle of the first sound and electronic equipment is larger, then can determine
First voice data is noise sound data.
