[0023] Unless explicitly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising”, etc., will be understood to include the stated elements or components but not to exclude other elements or components.
[0024] A multifunctional microphone stand, such as Figures 1 to 5 As shown, it includes: a bracket body 1, which is a tubular structure, and an angle positioning line 11 is provided on the outer surface of the bracket body 1, and the angle positioning line 11 is distributed along the height direction of the bracket body 1; a base 2, which is located at the bottom of the bracket body 1 and is used to support the bracket body 1; a microphone adjustment seat 3, including an adjustment seat body 31, the adjustment seat body 31 is a tubular structure with an inner diameter matching the outer diameter of the bracket body 1, and the adjustment seat body 31 is located outside the bracket body 1 and can slide and rotate freely on the bracket body 1; a first mounting member 3 2. The first mounting member 32 is located on the side wall of the adjustment seat body 31, and is used to fix the microphone adjustment seat 3 and the bracket body 1; the adjustment seat engraved line 33, the adjustment seat engraved line 33 is located on the inner surface of the adjustment seat body 31, and the adjustment seat engraved line 33 is distributed along the height direction of the adjustment seat body 31. By matching the adjustment seat engraved line 33 and the angle positioning line 11, the required rotation angle of the microphone adjustment seat 3 can be determined; the microphone installation position 34, the microphone installation position 34 is located on the side wall of the adjustment seat body 31, and is used to fix the microphone.
[0025] Specifically, determining the rotation angle of the microphone adjustment seat 3 means that by rotating the microphone adjustment seat 3, aligning the adjustment seat engraved line 33 and the angle positioning line 11, the position where the microphone adjustment seat 3 needs to be aligned is determined, thereby realizing rapid adjustment of the preset angle of the microphone. The microphone installation position 34 is arranged horizontally. The adjustment seat body 31 is located outside the bracket body 1, which means that the adjustment seat body 31 is sleeved on the outside of the bracket body 1.
[0026] As an optional embodiment, the outer surface of the bracket body 1 is also provided with a height positioning line 12, and the height positioning line 12 is distributed around the circumferential direction of the bracket body 1; the side wall of the adjustment seat body 31 is also provided with an observation window 35, and the observation window 35 is a long hollow structure. The observation window 35 is arranged along the circumference of the adjustment seat body 31, and the outer wall of the bracket body 1 wrapped by the microphone adjustment seat 3 can be seen through the observation window 35.
[0027] Specifically, the height positioning line 12 is used to meet the need to quickly adjust the microphone to a suitable height from the ground during the installation process. In the pass-by noise test project, the height of the microphone from the ground during the test needs to be 1.2 meters, and the height of the height positioning line 12 corresponds to it. The specific method of adjusting the height of the microphone is: make the microphone adjustment seat 3 pass through the bracket body 1 from the top, then make the microphone adjustment seat 3 gradually slide downward from the top of the bracket body 1, and when the height positioning line 12 is observed to pass through the observation window 35, stop sliding, and adjust the first mounting member 32 to fix the relative height of the microphone adjustment seat 3 and the bracket body 1, so as to achieve convenient adjustment of the microphone height. The observation window 35 is a long strip structure, which increases the length of the height positioning line 12 that can be observed and reduces the probability of misreading. As a preferred embodiment, the width of the observation window 35 is greater than the width of the height positioning line 12. The meaning of the observation window 35 being arranged along the circumference of the adjustment seat body 31 is that the observation window 35 is a long strip arc observation window 35 with an arc length greater than the width. As a preferred embodiment, the observation window 35 is at the same height as the microphone installation position 34 , so that when the height positioning line 12 passes through the observation window 35 , the height of the microphone can just meet the requirement of the height of the microphone from the ground.

[0031] Specifically, the bracket body 1 can be installed on the base 2 by aligning the first positioning pin 13 with the second positioning pin 23. The end of any end of the cross-shaped structure refers to the end of any structure where the corner of the cross-shaped structure extends outward from the mounting tube 21. The second positioning pin 23 faces the end of the cross structure. By observing the position of the end of the cross structure that the second positioning pin 23 faces, so that it faces the exhaust direction of the muffler, combined with the angle positioning line 11, the microphone can be conveniently adjusted to the 45 degree and -45 degree positions toward the muffler exhaust. Observing the end of the cross structure is more convenient and intuitive than observing the second positioning pin 23, and can improve the adjustment efficiency of the microphone.
[0032] As an optional implementation, the number of the angle positioning lines 11 is two, including a 45-degree positioning line 111 and a -45-degree positioning line 112 spaced apart in the circumferential direction of the bracket body 1 .
