Detailed description of the invention
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below in conjunction with the accompanying drawings
With embodiment, the present invention is specifically described.Accompanying drawing in describing below is only some realities of the present invention
Execute example.For those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to
Other accompanying drawing is obtained according to these accompanying drawings.
Carry out in semianechoic room in the prior art by (or the test of other similar demands during noise testing
Time), need in measured object both sides, be placed in parallel two row's mikes, length that generally will be the longest.Traditional
In the obviously regulation in terms of distance, the entire row depth of parallelism and height of single microphone holder form the most inconvenient.
The present invention, based on considerations above, devises microphone holder, can be fixed on support by multiple mikes,
And the spacing of mike, position etc. can be carried out harmonious regulation, easy to adjust, it is ensured that acoustics
