Abstract
The utility model discloses an acoustic test-used microphone support. The acoustic test-used microphone support includes at least two connecting rods and at least one connecting piece which is adjustably connected between two adjacent connecting rods; a microphone is mounted on one of the connecting rods; and the connecting piece can be adjusted so that the position of the microphone can move and/or rotate. Therefore, position change can be realized according to the shape and size of testing products, so that the microphone support can be adjusted, and therefore, multi-direction adjustment can be performed on the microphone, for example, the microphone can move upwards and downwards as well as leftwards and rightwards, and can rotate, and as a result, it can be ensured that each test can be located at an optimal test location.
Description
Technical field
The utility model relates to a kind of microphone arm, relates in particular to the microphone arm that a kind of acoustical testing is used.
Background technology
In acoustical testing, conventionally need to use microphone, wherein, microphone is the energy conversion device that voice signal is converted to the signal of telecommunication.Such as in test horn acoustic characteristic, microphone just need to be set in quiet room, after being converted to the signal of telecommunication by conveyer, the 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, supporting the support of microphone is a simple connecting rod, do not have the function that the directions such as upper and lower, left and right and rotation regulate, so the microphone on this support only have one towards.So just cause in the time of test different types product, microphone towards being adjusted to optimum orientation, cannot reach best test effect.
Utility model content
The purpose of this utility model is 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 realizing above-mentioned utility model object, the utility model 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, described connector is provided with the first connecting hole and the second connecting hole to accommodate respectively described adjacent two connecting rods, described the first connecting hole is parallel to each other with the second connecting hole or is mutually vertical, microphone is arranged on wherein on a connecting rod, regulate described connector can make the position of described microphone move and/or rotate.
In addition, the utility model also provides following attached technical scheme:
Described connector is also 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 connecting rod is made by round steel.
Described microphone arm is arranged in audiometric room.
Than prior art, advantage of the present utility model 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 move 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 is all positioned at best test position.

Fig. 1 is the microphone arm of using corresponding to the acoustical testing of the utility model preferred embodiment.
Fig. 2 is the cutaway view of a kind of contiguous block in the microphone arm of using corresponding to the acoustical testing of the utility model preferred embodiment.
Fig. 3 is the stereogram of another kind of contiguous block in the microphone arm of using corresponding to the acoustical testing of the utility model preferred embodiment.
Embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solutions of the utility model are further non-limitingly described in detail.
Referring to figs. 1 through Fig. 3, the microphone arm of using corresponding to the acoustical testing of the utility model preferred embodiment, 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 linear pattern round steel, and the 4th connecting rod 6 is bending-type round steel, and its optimum shape is roughly V-shaped.
In the present embodiment, the optimal number of connector 14 is 4.On each connector 14, be provided with the first connecting hole 21 and the second connecting hole 22, be respectively arranged with first and second screw hole 25,26 at the side of first and second connecting hole 21,22, 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 on second and third connector 8,9 21,22, first and second screw hole 25,26 are vertical mutually with groove 29,30.On first and second screw hole 25,26, be connected with screw (not shown), 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 be by regulating the screw on first and second screw hole 25,26 to change its radius size.In the time 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 because connecting rod 12 is for round steel is made, so regulate each connector 14 can rotate microphone.After position adjustments is good, screw screw, connecting rod 12 is fixedly connected with connector 14.
It is to be noted; above-mentioned preferred embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection range of the present utility model.
