[0035] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 1 The direction of the microphone body is "up" and the direction of the base is "down".

[0036] A desktop steering microphone proposed in an embodiment of the utility model includes a microphone body, a base and a rotating shaft. The rotating shaft body includes a bolt, a nut, a first damping turntable and a second damping turntable. The first damping turntable is fixed to the top of the fixed rod, and the second damping turntable is installed on the rotating part of the rotating device. One end of the bolt passes through and is fixed on the first damping turntable, and the other end passes through the second damping turntable and cooperates with the nut to hinge the rotating device and the fixed rod together; its beneficial effect is that the bolt is fixed and does not rotate, which can provide a stable support point for the entire steering structure. By arranging the second damping turntable and the rotating device to rotate on the bolt, the stability of the rotating shaft can be improved, and the technical problem that the steering force and speed of the existing conference microphone are difficult to control during steering, resulting in inaccurate steering angles, is solved.

[0037] To better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0038] Example 1:

[0039] Reference Figure 1 The embodiment of the present utility model provides a desktop steering microphone, which includes a microphone body 1, a rotating shaft and a base 3. The rotating shaft is fixed on the base 3, and the microphone body 1 is connected to the rotating shaft.

[0040] See Figures 1 to 4 The rotating shaft includes a rotating shaft body, a rotating device 4 and a fixed rod 5. The rotating device 4 is fixed at the rear end of the microphone body 1. The tail end of the fixed rod 5 is fixed on the base 3, and the top end is connected to the rotating device 4. The rotating shaft body includes a bolt 21, a nut 22, a first damping turntable 23, a second damping turntable 24, a gasket 26, a damping plate 27 and a sleeve 25.

[0041] The bolt 21 includes a bolt head and a connecting portion. The outer wall of the connecting portion is provided with threads that connect to the threads provided on the inner wall of the nut 22. The bolt 21 passes through the first damping rotary plate 23, the shaft sleeve 25, the washer 26, the second damping rotary plate 24, and the two damping plates 27 in sequence, and cooperates with the nut 22 to hinge the rotating device 4 and the fixed rod 5 together.

[0042] The cross-section of the connecting portion of the bolt 21 is drum-shaped, and the through holes of the first damping turntable 23 and the gasket 26 are both set to a drum shape that matches the connecting portion. The purpose of this setting is to clamp the following first damping turntable 23 and gasket 26 so that the bolt 21 is fixed in the first damping turntable 23 and the gasket 26 and cannot rotate, while the through holes of the second damping turntable 24 and the damping plate 27 are circular holes, so that the second damping turntable 24 and the rotating device can rotate on the bolt 21.

[0043] Continue reading Figure 2 Gaskets 26 are provided between the sleeve 25 and the second damping turntable 24, between the second damping turntable 24 and the adjacent damping plate 27, and between the nut 22 and the adjacent damping plate 27 to avoid direct contact between adjacent components and disperse pressure to reduce component wear. The gasket 26 has a certain elasticity and can absorb the vibration generated when the shaft is running, thereby effectively reducing the noise generated when the equipment is running and ensuring the quality of audio collection.

[0044] In the shaft body, the sleeve 25 is located between the first damping turntable 23 and the second damping turntable 24, and the two damping plates 27 are arranged between the second damping turntable 24 and the nut 22. By setting the front side of one damping plate 27 to be connected with the back side of the other damping plate 27, a V-shaped angle is formed at the connection point. The resistance generated by the damping plate can effectively control the rotation speed and force, preventing the microphone from rotating too fast or too slow, so that the user can adjust the direction of the microphone more accurately.

[0045] See Figures 2 to 7 The rotating device 4 also includes a mounting plate 42 mounted on the rotating part 41. The mounting plate 42 is fixed to the top of the rotating device 4 and is connected to the rear end of the microphone body 1. Openings are provided at both ends of the rotating part 41 to provide installation space for the shaft body. An annular step is provided in the rotating part 41, on which a second mounting hole 411 is provided. A through hole is provided on the second damping disc 24 corresponding to the second mounting hole 411. A screw passes through the through hole and cooperates with the second mounting hole 411 to fix the second damping turntable 24 on the rotating part 41, so that the second damping turntable 24 can drive the shaft device 4 to rotate in the rotating device mounting part of the fixed rod 5.

[0046] The fixing rod 5 is provided with a connecting rod 51 and a rotating device mounting portion fixed to the top of the connecting rod 51, wherein the rotating device mounting portion is a column-mounted housing. An opening is provided on one end face of the rotating device mounting portion, and a rotating window 53 is provided on the side. The inner wall of the opening is provided with three raised steps, and a first mounting hole 52 is provided on the raised steps. A through hole is provided on the first damping turntable 23 corresponding to the first mounting hole 52. A screw passes through the through hole and cooperates with the first mounting hole 52 to fix the first damping turntable 23 to the rotating device mounting portion. One end of the bolt 21 passes through and is fixed to the first damping turntable 23;

[0047] Two cover plates are mounted on the outside of the two end surfaces of the rotating device mounting portion. The tail end of the connecting rod 51 is connected to the base 3. The rotating device 4 is placed on the rotating device mounting portion, and its mounting plate 42 is exposed from the rotating window 53.

[0048] The rotating device 4 can only rotate up and down along the axis to adjust the position of the microphone body 1. The connecting rod 51 of the base 3 is relatively short and compact, which makes the center of gravity of the desktop steering microphone move downward, making the center of gravity more stable and not easy to tip over.

[0049] See Figure 2 、 Figure 4 and Figure 5 Both the rotating mechanism 4 and the fixed rod 5 are equipped with wiring holes. The power cable, electrically connected to the first circuit board of the microphone body 1, passes through the wiring hole, through the mounting plate 42 of the rotating mechanism 4, into the interior of the fixed rod 5, and then through the connecting rod 51 at the lower end of the fixed rod 5 into the base, where it is electrically connected to the second circuit board. As a result, the wiring of the entire conference system microphone is concealed, resulting in a rational structure and a more aesthetically pleasing appearance.

[0050] See Figure 1 The microphone body 1 includes a shell, a microphone core, a fixing bracket and a first circuit board. A plurality of hollow holes for sound pickup are evenly arranged on the top and side surfaces of the shell. A fixing bracket is arranged inside the shell, and multiple chambers are provided. The microphone core and the first circuit board are fixed in the corresponding chambers, making assembly faster and more convenient.

[0051] The base 3 includes a base upper cover, a second circuit board and a base lower cover. The second circuit board is fixed in the base lower cover, and a cable plug interface is provided on the rear end of the base lower cover. The base upper cover and the base lower cover are detachably connected together.
