Abstract
The invention discloses a microphone support capable of multipoint testing. The microphone support comprises a lower supporting piece, an upper supporting piece and a plurality of connecting rods which connect the upper supporting piece with the lower supporting piece. The lower supporting piece is provided with a center point which is used for supporting a product to be tested. A microphone can be mounted on each connecting rod. The distances between all the connecting rods and the center point are roughly equal. Therefore, multiple microphones can be mounted at the same time to conduct acoustic testing of the product to be tested in multiple directions.
Description
Technical field
The present invention relates to a kind of microphone arm, but relate in particular to a kind of transaudient support of multi-point sampler.
Background technology
In acoustical testing, sometimes need the multiple directions of a product are carried out to the sound test.During such as the test acoustical power, 6 to 10 microphones just need to be arranged at different directions, and all microphones all want the position of 1 meter of distance product to be tested.So, is necessary to design one and can fixes a plurality of microphones simultaneously, and each microphone is to the equal microphone arm of test products distance.
Summary of the invention
The object of the invention is to, for above-mentioned defect of the prior art, provides a kind of microphone arm, the acoustic characteristic that it can the multi-point sampler product.
For achieving the above object, the present invention has adopted following technical scheme: but a kind of microphone arm of multi-point sampler, it is characterized in that the many connecting rods that it comprises lower support element, upper supporting piece and connects upper and lower strutting piece, described lower support element has central point to place product to be tested, each root connecting rod can be installed microphone, each root connecting rod to central point the distance about equally.
In addition, the present invention also provides following attached technical scheme:
But the microphone arm of described multi-point sampler also comprises the top braces parts that are arranged on the upper supporting piece top, it comprises and is arranged on the upper frame on described upper supporting piece and is arranged on the connector on described upper frame, described upper supporting piece is connected with connecting rod, and described connector connects microphone.
Described upper supporting piece and lower support element the best are circular, and are parallel to each other.
Described connecting rod the best is arc.
But the microphone arm integral body of described multi-point sampler is made by round steel.
Than prior art, advantage of the present invention is: but the many connecting rods that the microphone arm of this multi-point sampler comprises lower support element, upper supporting piece and connects upper and lower strutting piece, lower support element has central point to place product to be tested, each root connecting rod can be installed microphone, each root connecting rod to central point the distance about equally.So it can install a plurality of microphones simultaneously, the multiple directions of test products are carried out to acoustical testing.
The accompanying drawing explanation
But Fig. 1 is corresponding to the microphone arm stereogram of the multi-point sampler of preferred embodiment of the present invention.
Embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solution of the present invention is further non-limitingly described in detail.
With reference to Fig. 1, but, corresponding to the microphone arm of the multi-point sampler of preferred embodiment of the present invention, it is mainly used in placing microphone, carries out the acoustical testing of product.In the present embodiment, whole of this microphone arm is made by round steel, and it comprises lower support element 12, upper supporting piece 14, many connecting rods 18 and top braces parts 22.Wherein, connecting rod 18 connects upper and lower strutting piece 14,12, and top braces parts 22 comprise the upper frame 23 be connected with upper supporting piece 14 and are arranged on the connector 24 on upper frame 23.
Particularly, above-mentioned lower support element 12 is rounded, and has central point a, and tested product is placed on central point a place.Above-mentioned connecting rod 18 is curved, and its optimal number is 6 in the present embodiment.One end and the lower support element 12 of connecting rod 18 are fixedly connected, and the Best link mode is welding, and the spacing between adjacent connecting rod 18 equates.Removably be connected with microphone on connecting rod 18, microphone equals the radius of lower support element 12 to the distance of central point a.Above-mentioned upper supporting piece 14 is rounded, has central point b.Upper supporting piece 14 is fixedly connected with the other end of connecting rod 18, and the Best link mode is welding, and similarly, the spacing between adjacent connecting rod 18 equates.Above-mentioned upper frame 23 is comprised of the many round steel with perpendicular corners, and its optimal number is 4.Upper frame 23 is welded on upper supporting piece 14, and the spacing of the tie point on upper supporting piece 14 equates.Connector 24 is welded on upper frame 23, is mainly used in connecting microphone, and this microphone equals the radius of lower support element 12 to the distance of central point a.In the present embodiment, the microphone on connector 24 and central point a, b are located on the same line, and perpendicular to lower support element 12 and upper supporting piece 14.
When test, test products is placed on to the central point a place of lower support element 12, because the distance of the microphone on the microphone on connecting rod 18 and connector 24 to central point a equates, and all with the radius of lower support element 12, equate.Quantity due to connecting rod 18 is 6 again, so this microphone arm can be fixed a plurality of microphones simultaneously, and measuring distance is equal, meets the demand of multi-point sampler.
It is pointed out that above-mentioned preferred embodiment is only explanation technical conceive of the present invention and characteristics, its purpose is to allow the person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
Claims (5)
1. but the microphone arm of a multi-point sampler, it is characterized in that the many connecting rods that it comprises lower support element, upper supporting piece and connects upper and lower strutting piece, described lower support element has central point to place product to be tested, each root connecting rod can be installed microphone, each root connecting rod to central point the distance about equally.
2. but the microphone arm of multi-point sampler according to claim 1, it is characterized in that it also comprises the top braces parts that are arranged on the upper supporting piece top, it comprises and is arranged on the upper frame on described upper supporting piece and is arranged on the connector on described upper frame, described upper supporting piece is connected with connecting rod, and described connector connects microphone.
