Specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail, but the protection scope of the utility model is unlimited
In following embodiment.
A kind of array surface that microphone arrangement mode is variable, including arraying bread board 1, as shown in Figure 1, being set on arraying bread board 1
It is equipped with microphone slot 2, microphone slot 2 is square array arrangement, and microphone slot 2 matches with microphone 3, i.e. array surface
Multiple microphone slots 2 are provided on plate 1, microphone 3 can need that suitable microphone slot 2 is selected to be inserted into according to array, such as
Arrangement is in cross array, circular array, rectangular array or spiral shape, i.e., respectively such as Fig. 2, Fig. 3, Fig. 4 and shape shown in fig. 5
Formula, microphone 3 can so be able to achieve the quick fixation of microphone 3 with quick insertion.It can so be conducive to improve transform array row
The working efficiency of column mode, and by the transformation of different arrays, the accuracy rate of live transformer noise identifing source can be improved.
Further, the present embodiment needs to provide specific quantity according to field operation, in general, microphone slot
2 are provided with M row and N column, the integer that M and N are 5 or more.The specific value that the present embodiment uses are as follows: M=25, N=25, i.e. microphone
Slot 2 totally 625, each 2 diameter 2cm of microphone slot, between microphone slot 2 between be divided into 2cm.
It further, is the array position for preferably assisting in microphone insertion, the present embodiment further includes array instruction
Board 4, array direction board 4 is identical as 1 size of arraying bread board and size, and array direction board 4 includes cross array direction board, circle
