Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, below in conjunction with attached drawing and specific implementation
The utility model is described in detail in example.
The utility model fixes Mike using adhesive tape and wooden unit on glass and vehicle body sheet metal in usual NVH test
Wind, heavy workload and easy the problem of scratching vehicle paint, provide a kind of microphone fixator.
As shown in Figures 1 to 4, the utility model embodiment provides microphone fixator, comprising:
Positioning plate 1；
Shackle member is fixedly connected with the positioning plate 1, and the shackle member includes the upper table for protruding from the positioning plate 1
The clamping groove 2 of face setting, the size of the clamping groove 2 are matched with the size of microphone to be fixed；
Sucker 3 is set to the lower surface of the positioning plate 1.
It should be noted that microphone is fixed in test point by the microphone fixator when carrying out NVH test,
The design of sucker 3 can effectively increase adsorption area, convenient for being fixed on the vehicle body sheet metal or glass of out-of-flatness, and
And it is easy for assemble or unload；The microphone fixator selects plastic material, light weight and at low cost；Meanwhile the microphone is fixed
Device height is moderate, can effectively improve the accuracy of test.
Specifically, mounting hole 4 is offered on the positioning plate 1, it is preferable that 1 shape of positioning plate is circle, the peace
Dress hole 4 is located at the center of the positioning plate 1.
In order to guarantee test point accuracy, microphone needs at a distance from 2 to 3 centimetres between glass or vehicle body sheet metal,
It is typically required one piece of high 2 to 3 centimetres of wood particle of pad between microphone and glass or vehicle body sheet metal, but wooden unit is easy to draw
