Description

Technical Field

[0001] This utility model relates to the field of microphone technology, specifically a conference microphone that can rotate in six directions. Background Technology

[0002] In large conference rooms or meeting halls, when the host needs to speak, they often need to use a microphone to amplify their voice so that the audience can hear them.

[0003] A typical conference microphone structure consists of a base and a microphone stand. The base is generally used for fixation, and the microphone stand has a pickup head at the top. This structure only supports adjustment in one direction (such as only pitch) or limited directions, which cannot guarantee that the microphone tube is accurately aligned with the target position, resulting in positioning deviation due to insufficient adjustment dimensions. Utility Model Content

[0004] The purpose of this invention is to provide a conference microphone that can rotate in six directions to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conference microphone that can rotate in six directions, including a microphone tube, wherein a tail pin is fixed at the tail end of the microphone tube, and a toothed frame is fixedly connected to the front end of the tail pin, and the toothed frame constitutes the bottom foundation of the microphone tube.

[0006] Furthermore, a sliding seat is provided at the bottom of the microphone tube, and the cross-sectional shape of the sliding seat is "I". A pitch pin is fixedly connected to the bottom of the sliding seat, and a gear is rotatably installed inside the sliding seat.

[0007] Furthermore, the toothed frame groove has an "I"-shaped throat portion of a sliding seat that slides within it, and the tooth profile at the side end of the toothed frame groove meshes with the gear inside the sliding seat.

[0008] Furthermore, the bottom of the pitch pin is connected to a pitch seat, and the pitch seat has an inlet that cooperates with the pitch pin to rotate up and down, and an adjusting bolt is connected to the side of the pitch seat.

[0009] Furthermore, the bottom of the pitch seat is connected to a mating pin, which is inserted into the end pin of the rotary seat.

[0010] Furthermore, the rotating seat is rotatably installed inside the connecting screw sleeve, and the bottom end of the connecting screw sleeve is internally threaded with a connecting piece.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. In use, this utility model firstly involves pulling the microphone housing back and forth along the axial direction. The sliding seat with an "I"-shaped throat portion slides within the toothed frame groove. The microphone then extends and retracts by meshing the teeth on the side of the toothed frame groove with the gear inside the sliding seat. Secondly, the pitch pin fixed to the bottom of the sliding seat adjusts the microphone's vertical rotation angle by rotating the inlet located inside the pitch seat, and the angle is fixed by connecting bolts. Finally, the bottom of the pitch seat is connected to the pin at the end of the rotating seat. The microphone's left and right rotation is adjusted by rotating the rotating seat within the annular groove in the middle of the connecting screw sleeve. This solution, through a combination of extension and retraction, vertical pitch, and left and right rotation, directly covers six-way adjustment of the microphone in three-dimensional space. Compared to traditional microphone structures that only support single-direction or limited-direction adjustment, this solution allows the microphone to be precisely aligned with the target position, avoiding positioning deviations caused by insufficient adjustment dimensions. It is especially suitable for scenarios such as conference rooms where frequent microphone position adjustments are required. Attached Figure Description

[0014] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0015] like Figure 3 As shown, a conference microphone that can rotate in six directions includes a microphone tube 1, a tail pin 5 fixed at the tail end of the microphone tube 1, and a toothed frame 6 fixedly connected to the front end of the tail pin 5. The toothed frame 6 forms the bottom base of the microphone tube 1. A sliding seat 2 is provided at the bottom end of the microphone tube 1, and the cross-sectional shape of the sliding seat 2 is "I". A pitch pin 3 is fixedly connected to the bottom end of the sliding seat 2, and a gear 4 is rotatably installed inside the sliding seat 2. The "I"-shaped throat part of the sliding seat 2 slides in the groove of the toothed frame 6, and the tooth profile on the side end of the groove of the toothed frame 6 meshes with the gear 4 inside the sliding seat 2. The specific operation is as follows: Hold the microphone tube 1 and pull it back and forth along the axis. The sliding seat 2 with an "I"-shaped throat part slides in the groove of the tooth frame 6. Then, the microphone tube 1 can move back and forth by meshing with the gear 4 inside the sliding seat 2 through the tooth shape on the side end of the groove of the tooth frame 6. like Figures 1 to 2 As shown, the bottom of the pitch pin 3 is connected to the pitch seat 7, and the pitch seat 7 has an inlet 8 that is engaged with the pitch pin 3 to rotate up and down. The side of the pitch seat 7 is connected to the adjusting bolt 9, and the bottom of the pitch seat 7 is connected to the mating pin 10. The mating pin 10 is inserted into the pin body at the end of the rotating seat 11. The rotating seat 11 is rotatably installed inside the connecting thread sleeve 12, and the bottom end of the connecting thread sleeve 12 is internally threaded with the connecting piece 13. The specific operation is as follows: The pitch pin 3, which is fixed to the bottom of the sliding seat 2, adjusts the up and down rotation angle of the microphone tube 1 by rotating the inlet 8 located inside the pitch seat 7, and fixes the angle by connecting bolts. The bottom of the pitch seat 7 is connected to the pin 10 at the end of the rotating seat 11. The left and right rotation adjustment of the microphone tube 1 is achieved by rotating the rotating seat 11 in the annular groove in the middle of the connecting screw sleeve 12. This solution directly covers the six-way adjustment of the microphone tube 1 in three-dimensional space through the combination design of front and rear extension, up and down pitch and left and right rotation.

[0016] It should be further explained that: the central flange of the rotating seat 11 is provided with a spring piece, and the groove on the inner wall of the connecting screw sleeve 12 is provided with annular teeth. When the rotating seat 11 rotates within the annular groove of the connecting screw sleeve 12, the damping adjustment effect is achieved through the engagement of the spring piece. The above scheme is a common damped rotation adjustment method in the prior art, which is not elaborated in this application.

[0017] Working principle: First, the microphone housing 1 is pulled back and forth along the axial direction. The "I"-shaped throat part of the sliding seat 2 slides in the groove of the gear frame 6. Then, the back-and-forth extension and retraction of the microphone 1 is achieved by the meshing of the side teeth of the groove of the gear frame 6 with the gear 4 inside the sliding seat 2. Second, the pitch pin 3 fixed to the bottom of the sliding seat 2 adjusts the up-and-down rotation angle of the microphone 1 by rotating the inlet 8 inside the pitch seat 7, and the angle is fixed by the connecting bolt. Finally, the bottom of the pitch seat 7 is connected to the pin at the end of the rotating seat 11. The left and right rotation adjustment of the microphone 1 is achieved by rotating the rotating seat 11 in the annular groove in the middle of the connecting screw sleeve 12. This solution directly covers the six-way adjustment of the microphone 1 in three-dimensional space through the combination design of back-and-forth extension, up-and-down pitch, and left and right rotation. Compared with the traditional microphone structure that only supports single-direction or limited-direction adjustment, this solution allows the microphone 1 to be accurately aligned with the target position, avoiding positioning deviation caused by insufficient adjustment dimensions. It is especially suitable for scenarios such as conference rooms where the position of the microphone 1 needs to be frequently adjusted.
