Abstract
The invention discloses a microphone support for acoustic testing. The microphone support comprises at least two connecting rods and at least one connecting piece which is adjustably connected between two adjacent connecting rods. A microphone is arranged on one of the connecting rods. The microphone can move and/or rotate by adjusting the connecting piece. Accordingly, the position can be changed for adjusting the microphone support according to the shape and size of a tested product so that the microphone can be adjusted in multiple directions by moving up and down, left and right and rotating, and the fact that the support is placed at the best testing position each time is guaranteed.
Description
Technical field
The present invention relates to a kind of microphone arm, relate in particular to the microphone arm that a kind of acoustical testing is used.
Background technology
In acoustical testing, usually need to use microphone, wherein, microphone is voice signal to be converted to the energy conversion device of the signal of telecommunication.Such as in the test horn acoustic characteristic, just microphone need to be set in quiet room, after being converted to the signal of telecommunication by conveyer, sound that loudspeaker send demonstrates its related data by related software again, just can know the acoustic characteristic of these loudspeaker.But, in existing quiet room, the support that supports microphone is a simple connecting rod, do not have the function that the directions such as upper and lower, left and right and rotation are regulated, so the microphone on this support only have one towards.So just cause when the test different types product, microphone towards being adjusted to optimum orientation, can't reach best test effect.
Summary of the invention
The object of the invention is to for above-mentioned defect of the prior art the microphone arm of provide that a kind of microphone can carry out up and down, the acoustical testing of the multi-direction adjusting such as left and right and rotation being used.
For achieving the above object, the present invention has adopted following technical scheme: the microphone arm that a kind of acoustical testing is used, it is characterized in that it comprises that at least two connecting rods and adjustable ground are connected at least one connector between adjacent two connecting rods, microphone is arranged on wherein on a connecting rod, regulates the position that described connector can make described microphone and is moved and/or rotate.
In addition, the present invention also provides following attached technical scheme:
Described connector is provided with the first connecting hole and the second connecting hole to accommodate respectively described adjacent two connecting rods.
Described connector also is provided with the screw hole that lays respectively at the first connecting hole and the second connecting hole side.
In described screw hole, screw is installed, regulates described screw, can change the pore size of first and second connecting hole.
The side of described connector offers groove, and described groove is connected with described screw hole and is mutually vertical.
Described groove is connected with described the first connecting hole or described the second connecting hole.
Described the first connecting hole is parallel to each other with the second connecting hole or is mutually vertical.
Described connecting rod is made by round steel.
Described microphone arm is arranged in audiometric room.
Than prior art, advantage of the present invention is: the microphone arm that this acoustical testing is used comprises at least two connecting rods and adjustable ground is connected at least one connector between adjacent two connecting rods, microphone is arranged on wherein on a connecting rod, and adjusting connector can make the position of microphone be moved and/or rotate.So, can change position according to the shape size of test products, regulate this microphone arm, make that microphone can carry out up and down, the multi-direction adjustment such as left and right and rotation, guarantee that each test all is positioned at best test position.

The microphone arm of Fig. 1 for using corresponding to the acoustical testing of preferred embodiment of the present invention.
Fig. 2 is the cutaway view of a kind of contiguous block in the microphone arm of using corresponding to the acoustical testing of preferred embodiment of the present invention.
Fig. 3 is the stereogram of another kind of contiguous block in the microphone arm of using corresponding to the acoustical testing 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.
Referring to figs. 1 through Fig. 3, the microphone arm of using corresponding to the acoustical testing of preferred embodiment of the present invention, it is mainly used in connecting the microphone that acoustical testing is used.This microphone arm comprises that at least two connecting rods 12, adjustable ground are connected at least one connector 14 between adjacent two connecting rods 12 and are connected to the microphone (not shown) on one of them connector 14.
In the present embodiment, the optimal number of connecting rod 12 is 4, and its best making material is round steel.Particularly, connecting rod 12 comprises head rod 3, the second connecting rod 4, the 3rd connecting rod 5 and the 4th connecting rod 6, and wherein first, second and third connecting rod 3,4,5 is the linear pattern round steel, and the 4th connecting rod 6 is the bending-type round steel, and its optimum shape is roughly V-shaped.
In the present embodiment, the optimal number of connector 14 is 4.Be provided with the first connecting hole 21 and the second connecting hole 22 on each connector 14, at the side of first and second connecting hole 21,22, be respectively arranged with first and second screw hole 25,26, offer respectively groove 29,30 at the dual-side of connector 14 simultaneously.Wherein, groove 29 is connected with the first screw hole 25, the first connecting hole 21, and mutually vertical with the first screw hole 25; Groove 30 is connected with the second screw hole 26, the second connecting hole 22, and mutually vertical with the second screw hole 26.Particularly, connector 14 comprises the first connector 7, the second connector 8, the 3rd connector 9 and the 4th connector 10.Wherein, first, fourth connector 7,10 is roughly symmetrical structure, and first and second connecting hole 21,22 disposed thereon is parallel mutually with first and second screw hole 25,26; First and second connecting hole 21,22, first and second screw hole 25,26 on second and third connector 8,9 are vertical mutually with groove 29,30.Be connected with the screw (not shown) on first and second screw hole 25,26, adjustment screw, can change the width of groove 29,30 and the radius of first and second connecting hole 21,22.
Particularly, connector 14 connects respectively two adjacent connecting rods 12.In the present embodiment, head rod 3 connects respectively anechoic chamber (not shown) and the first connector 7; The second connecting rod 4 connects respectively first and second connector 7,8; The 3rd connecting rod 5 connects respectively second and third connector 8,9; The 4th connecting rod 6 connects respectively third and fourth connector 9,10; Microphone is connected on the 4th connector 10.Wherein, first and second connecting hole 21,22 on each connector 14 all can change its radius size by the screw of regulating on first and second screw hole 25,26.When unclamping screw, it is large that the aperture of first and second connecting hole 21,22 becomes, so, can change the height of microphone by mobile the second connecting rod 4, the second connector 8, the 4th connecting rod 6 and the 4th connector 10, can change the position, left and right of microphone by mobile the 4th connecting rod 6, again due to connecting rod 12 for round steel is made, can rotate microphone so regulate each connector 14.After position adjustments is good, screw screw, connecting rod 12 is fixedly connected with connector 14.
