Abstract
Present invention is disclosed a kind of loudspeaker test bracket, it is characterised in that：Multiple microphone fixed chucks (2) are provided with the loudspeaker test bracket (1), the microphone fixed chuck (2) is that the center of circle is equally spaced into semicircle with the loudspeaker (3).The loudspeaker test bracket (1) is shaped as the semi-annular shape for the center of circle with the loudspeaker (3).This loudspeaker test bracket is simple in construction, in that context it may be convenient to fixed multiple microphones, ensure that microphone is in same level, and angular distribution equal with the distance of test horn uniformly, so that convenient test loudspeaker, improves the effect of test.
Description
Technical field
The present invention relates to a kind of loudspeaker test bracket.
Background technology
Many loudspeaker manufacturers are, it is necessary to acoustical behavior of the test horn under different angles, point, level side centered on loudspeaker
To from 0 degree --- all angles of 180 degree are tested, and each angle is placed a microphone and tested.
General way is to arrange multiple microphone holders around loudspeaker semi-circular, such as 10 supports, and by Mike
The height of wind be adjusted to loudspeaker sustained height, disadvantage of this is that workload is big, and it is difficult to ensure that all microphones all
In same horizontal plane, with Radius, and angular distribution is uniform.
The content of the invention
It is an object of the invention to can ensure that all microphones are equal there is provided one kind for drawbacks described above of the prior art
With the equidistant loudspeaker test bracket of test horn.
For achieving the above object, present invention employs following technical scheme：A kind of loudspeaker test bracket, its feature exists
In：Be provided with multiple microphone fixed chucks on the loudspeaker test bracket, the microphone fixed chuck and the loudspeaker away from
From equal.
In addition, the present invention also proposes following attached technical scheme：
The microphone fixed chuck is equally spaced into semicircle.
The loudspeaker test bracket is shaped as semi-annular shape.
The microphone fixed chuck is located in same level with the loudspeaker.
Compared to prior art, the advantage of the invention is that：This loudspeaker test bracket is simple in construction, in that context it may be convenient to fixed
Multiple microphones, ensure that microphone is in same level, and angular distribution equal with the distance of test horn uniformly,
So as to the convenient effect tested loudspeaker, improve test.
Brief description of the drawings
Fig. 1 is the structural representation of loudspeaker test bracket of the present invention.
Fig. 2 is the use schematic diagram of loudspeaker test bracket of the present invention.
Embodiment
Technical solution of the present invention is further non-limitingly described in detail below in conjunction with preferred embodiment and its accompanying drawing.
As shown in figure 1, the loudspeaker test bracket of the present invention is in semi-annular shape, the loudspeaker test bracket 1 is arranged on metope 4
, it is necessary to which the loudspeaker 3 of test are arranged on metope 4 and in the center of loudspeaker test bracket 1 on (metope 4 can also be substituted for shelf)
Position, be further opened with mounting hole 5 on metope 4 to facilitate and place loudspeaker 3.With the support semicircular ring on loudspeaker test bracket 1
To be that the center of circle is distributed with multiple spacing equal and be scattered in semicircular microphone fixed chuck 2 at center (i.e. loudspeaker where locate),
The microphone fixed chuck 2 is used to fix microphone 6.Microphone 6 is attached into microphone fixed chuck 2 when using to be carried out
Test, due to microphone fixed chuck 2 centered on loudspeaker 3 equidistantly distributed into semicircle, therefore, each microphone 6 and loudspeaker
3 apart from equal, and angle interval is uniform, can obtain preferably test effect.It can be needed to make according to test in addition
Greater or lesser annulus, or set on loudspeaker test bracket 1 and multiple rows of to be distributed centered on loudspeaker 3 into different radii semicircle
Microphone fixed chuck 2, to meet the test needs of different distance.
The loudspeaker test bracket of the present invention passes through rational structure design, it is ensured that when loudspeaker are tested, microphone is same
On one horizontal plane, and it is identical with the distance of loudspeaker, and angular distribution is uniform, substantially increases the test effect of loudspeaker.
It is pointed out that the technical concepts and features of above-mentioned preferred embodiment only to illustrate the invention, its object is to
Person skilled in the art can understand present disclosure and implement according to this, the protection of the present invention can not be limited with this
Scope.Any equivalent change or modification in accordance with the spirit of the invention, should all be included within the scope of the present invention.
