Embodiment Construction

[0019] Depend on Figure 1-2 Combining the shown structures, it can be seen that this kind of fixing device for noise measurement microphone includes a connecting piece connected to the vehicle body and a clamping device 1 for fixing the microphone on the connecting piece. It is long, and the two ends of the elastic band 2 are provided with self-coupling adhesive cloth, which can adapt to the length of the headrest of each vehicle model and adjust the tension by adjusting the bonding position of the self-coupling adhesive cloth.

[0020] The clamping device 1 includes a clip 11 and a buckle 12 integrally connected with the clip 11. The clamping device 1 is injection-molded with plastic material, and the buckle 12 is used to be fixed on the elastic band 2; Move up and down and fix the elastic band 2 on the headrest to adjust the position of the microphone,

[0021] Fixing methods using the above-mentioned fixing devices for noise measurement microphones include:

Abstract

The invention discloses a fixing device for a noise measurement microphone and a fixing method thereof. The fixing device comprises an elastic band (2) connected with a vehicle body and a clamping device (1) used for fixing the microphone on the elastic band (2), wherein the elastic band (2) is long strip-shaped, and provided with self-coupling viscose cloth at the two ends; and the clamping device (1) comprises a clamp (11) and a buckle (12) being integrally connected with the clamp (11) and fixed on the elastic band (2). With the structure, the fixing device for the noise measurement microphone can adapt to headrest lengths of the various vehicles by adjusting the bonding position of the self-coupling viscose cloth, and can adjust the tensioning force, and the position of the microphone can be adjusted by moving the microphone clamping device back and forth on the elastic band and adjusting the fixing position of the elastic band on a headrest, so that the universality of the fixing device is increased, and the fixation of all testing points in various vehicles can be achieved.

Description

technical field [0001] The invention relates to a fixing device, in particular to a fixing device for a noise measuring microphone and a fixing method thereof. Background technique [0002] At present, in the process of vehicle noise development at home and abroad, the position of the driver and the position of the software operator cannot place a dummy system to collect noise data. Usually, the microphone is fixed to the headrest of the seat by tying rope or sticking tape. It is also fixed with metal brackets. However, the microphone cannot be fixed firmly by using rope or adhesive tape, and it is inconvenient to operate; while the metal bracket is fixed, although it is firm, it is not very convenient to fix it with tools such as wrenches, and the protruding part of the bracket is easy to be damaged when the vehicle is in an emergency. When braking, there is a hidden danger to the safety of people in the car. Contents of the invention [0003] The technical problem to b...
