Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in figures 1-4, in car described in the utility model, the microphone stationary installation of air-conditioning noise test comprises the first vertical rod 1 and the second vertical rod 2, the two vertical rod 0.4m apart that length is 1m; First slide bar 3 of long 1m ~ 1.2m is arranged in the first vertical rod 1 and the second vertical rod 2 with the symmetrical level of the second slide bar 4 of long 0.5m, and the second slide bar 4 is positioned on the first slide bar 3.Described first vertical rod 1, second vertical rod 2 vertical rod, the first slide bar 3 and the second slide bar 4 are equipped with chute 7, first slide bar 3 is connected with two vertical rods respectively by two pairs of screw bolt and nut with the second slide bar 4, and described bolt can move up and down along chute 7 height determining the first slide bar 3 and the second slide bar 4; The chute 7 of described first slide bar 3 and the second slide bar 4 is provided with multiple microphone dop 6.The bottom of described vertical rod is supported by A-frame 5.
Two slide bars all regulate by bolt and move up and down in vertical rod, are then bolted at desired height.
First slide bar 3 is installed 4 to be regulated by bolt and can move left and right on slide bar and the microphone dop 6 in direction can be rotated freely, wherein 2 between two vertical rods, another two are positioned at two vertical rod both sides; Second slide bar 4 is installed 2 and regulated the microphone dop 6 that can move left and right on slide bar and also can rotate freely direction by bolt, all between two vertical rods.
As shown in Figure 2, described microphone dop 6 has internal thread, is arranged on the chute 7 of the first slide bar 3 or the second slide bar 4 by bolt.Described chute 7 penetrates place vertical rod, the first slide bar 3 or the second slide bar 4.Described microphone dop 6 is regulated by bolt and can move left and right on the first slide bar 3 or the second slide bar 4 and sense of rotation.
During test, multiple microphone is separately fixed on microphone dop 6, when two air-conditioner air outlets of the panel board left and right sides in automobile and two air-conditioner air outlets in panel board centre position are positioned on different level, first up-down adjustment first slide bar 3 and the second slide bar 4 to air-conditioner air outlet position, more respectively on left and right adjusting first slide bar 3 on 2 microphones and the second slide bar 42 microphones distinguish testing air conditioner air outlet noises; When in automobile, four air-conditioner air outlets are positioned in same level, first up-down adjustment first slide bar 3 to air-conditioner air outlet position, four microphone testing air conditioner air outlet noises on left and right adjusting first slide bar 3.
