Description

Technical Field

[0001] This utility model relates to the field of microphones, and more particularly to a novel conference microphone. Background Technology

[0002] In meetings, discussions, lectures, or other forms of group communication, conference microphones are used to improve communication efficiency and ensure sound quality, especially in situations involving multiple participants or remote individuals, ensuring that everyone's voice is clearly conveyed to others. These microphones are typically placed on the conference table beforehand so they can be readily used at the start of the meeting.

[0003] During meetings, microphones are usually placed directly on the table to make it easier for people to adjust them to a suitable position. However, most microphones have small bases and poor stability. During meetings or cleaning, the microphones are easily bumped and fall onto the table, causing noise or damage. Therefore, a new type of conference microphone is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a new type of conference microphone, which aims to improve the problem that the microphone base in the prior art is small and easily bumped and dropped.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel conference microphone, comprising a base, a spring tube fixedly connected to the top of the base, a microphone fixedly connected to the other end of the spring tube, a round rod rotatably connected to the inner top of the base, a rotating rod rotatably connected to the inner top of the base, a support rod fixedly connected to the outer periphery of the rotating rod, a gear assembly fixedly connected to the outer periphery of the round rod and the rotating rod, a connecting column rotatably connected to the inner top of the base, a movable block and a top block fixedly connected sequentially from top to bottom to the outer periphery of the connecting column, a connecting block fixedly connected to the inner top of the base, and an elastic component slidably connected to the middle of the connecting block; the elastic component includes a slider, the slider slidably connected to the middle of the connecting block, a limit block fixedly connected to one end of the slider, a limit groove formed in the middle of the movable block, the limit block slidably connected to the middle of the limit groove, a push block fixedly connected to the other end of the slider, a compression spring sleeved on the outer periphery of the slider, and the push block penetrating and slidably connected to the middle of the rear wall of the base.

[0006] Twisting the screw block drives the round rod to rotate. Under the action of the gear assembly, the rotating rod drives the support rod to rotate out from the bottom of the base, thereby increasing the support points of the base so that the microphone can be more stable. At the same time, the top block can prevent the support rod from shaking due to the gear reversal. Pressing the push block can push the top block out of the tooth groove through the movable block and the connecting block, thereby retracting the support rod.

[0007] As a further description of the above technical solution: a threaded tube is fixedly connected to the outer periphery of the spring tube, a support column is fixedly connected to the outer periphery of the threaded tube, a dust cover is rotatably connected to the outer periphery of the support column, a threaded sleeve is threadedly connected to the outer periphery of the threaded tube, a push-pull plate is rotatably connected to the outer periphery of the threaded sleeve, and a connecting component is installed between the push-pull plate and the dust cover.

[0008] Tightening the threaded sleeve moves it around the outer circumference of the threaded tube, allowing the push-pull plate to push or pull the dust cover through the connecting assembly. This allows the dust cover to be closed or opened under the action of the support column, thereby protecting the microphone and preventing dust from falling into the microphone and causing blockage and damage.

[0009] As a further description of the above technical solution: the gear assembly includes a first gear and a second gear, the first gear is fixedly connected to the outer periphery of the round rod, the second gear is fixedly connected to the outer periphery of the rotating rod, and the first gear meshes with the second gear.

[0010] When the round rod rotates, it drives gear one. Under the meshing action, gear one can drive the rotating rod to rotate through gear two.

[0011] As a further description of the above technical solution: the connecting assembly includes a positioning block and a connecting rod. The positioning block is fixedly connected to the outside of the dust cover. A sliding groove is provided in the middle of the positioning block. One end of the connecting rod is rotatably connected to the outside of the push-pull plate. The other end of the connecting rod is rotatably connected to a sliding rod. The sliding rod is slidably connected to the middle of the sliding groove.

[0012] When the push-pull plate moves, it will drive the connecting rod to move, and the connecting rod will drive the sliding rod to slide in the sliding groove, thereby pulling and pushing the positioning block so that the positioning block can drive the dust cover to unfold or close.

[0013] As a further description of the above technical solution: a spring is fixedly connected to the outer periphery of the round rod, and the other end of the spring is fixedly connected to the right side of the inner wall of the base.

[0014] When the gear rotates, it will cause the mainspring to contract. After pressing the push block, the top block will slide out of the tooth groove of the gear. The mainspring will then reset and drive the round rod to rotate, thereby quickly driving the support rod to retract into the bottom of the base.

[0015] As a further description of the above technical solution: the bottom of the support rod is fixedly connected with an anti-slip pad.

[0016] The anti-slip pads can increase friction, making the base more stable on the table.

[0017] As a further description of the above technical solution: the outer periphery of the round rod is fixedly connected with a screw block, which allows the round rod to be rotated more conveniently under the action of the screw block;

[0018] As a further description of the above technical solution: the edge of the dust cover is provided with a notch.

[0019] The notch prevents the dust cover from obstructing rotation.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, through the cooperation of gear one, gear two, support rod, round rod and other structures, the rotating screw block can drive gear one to rotate together through the round rod, gear one drives the rotating rod to rotate through gear two, and the rotating rod drives the support rod to unfold from the bottom of the base, so as to improve the stability of the conference microphone and reduce the occurrence of the conference microphone falling and being damaged due to collision.

[0022] 2. In this utility model, with the cooperation of structures such as threaded tube, threaded sleeve, connecting rod, and dust cover, when the rotating threaded sleeve moves around the outer circumference of the threaded tube, the threaded tube can be pulled or pushed by the push-pull plate so that the connecting rod can drive the dust cover to unfold or close. Thus, when the microphone is not in use, the dust cover can be used to cover the microphone to prevent dust from falling on the microphone. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-4 This utility model provides an embodiment of a novel conference microphone, comprising a base 1, a spring tube 2 fixedly connected to the top of the base 1, a microphone 10 fixedly connected to the other end of the spring tube 2, a round rod 18 rotatably connected to the inner top of the base 1, a rotating rod 12 rotatably connected to the inner top of the base 1, a support rod 3 fixedly connected to the outer periphery of the rotating rod 12, a gear assembly fixedly connected to the outer periphery of the round rod 18 and the rotating rod 12, the gear assembly including a first gear 13 and a second gear 15, the first gear 13 fixedly connected to the outer periphery of the round rod 18, the second gear 15 fixedly connected to the outer periphery of the rotating rod 12, the first gear 13 and the second gear 15 meshing, a connecting post 26 rotatably connected to the inner top of the base 1, a movable block 20 and a top block 17 fixedly connected sequentially from top to bottom to the outer periphery of the connecting post 26, a connecting block 24 fixedly connected to the inner top of the base 1, an elastic component slidably connected to the middle of the connecting block 24, and a screw block 14 fixedly connected to the outer periphery of the round rod 18. Firstly, when preventing the microphone from falling over, turning the screw block 14 causes the round rod 18 to rotate. The round rod 18 simultaneously drives the gear 13 to rotate. Since the round rod 18 meshes with the gear 15, the gear 13 can drive the gear 15 to rotate. As the gear 15 rotates, it will drive the rotating rod 12 to rotate, so that the rotating rod 12 can rotate the support rod 3 from the bottom of the base 1. This increases the support points of the base 1, thereby reducing the possibility of the microphone falling over due to collisions with the microphone 10 during use or cleaning, and improving the safety of the microphone.

[0033] Reference Figures 2-4 The elastic component includes a slider 30, which is slidably connected to the middle of the connecting block 24. One end of the slider 30 is fixedly connected to a limiting block 25. A limiting groove 23 is opened in the middle of the movable block 20. The limiting block 25 is slidably connected to the middle of the limiting groove 23. The other end of the slider 30 is fixedly connected to a push block 21. A compression spring 22 is sleeved on the outer periphery of the slider 30. The push block 21 passes through and is slidably connected to the middle of the rear wall of the base 1. A spring 19 is fixedly connected to the outer periphery of the round rod 18. The other end of the spring 19 is fixedly connected to the right side of the inner wall of the base 1. An anti-slip pad 11 is fixedly connected to the bottom of the support rod 3. When gear 13 rotates, it causes the spring 19 to contract and the outer teeth to move the top block 17. The top block 17 drives the movable block 20 to rotate through the connecting column 26. The movable block 20 pulls the slider 30 to slide in the middle of the connecting block 24 through the limit block 25. At the same time, the slider 30 can drive the push block 21 and squeeze the compression spring 22 under the action of the connecting block 24. When the tooth groove of gear 13 is aligned with the tip of the top block 17, the compression spring 22 will lose pressure and push the push block 21, so that the top block 17 resets and locks gear 13, thereby preventing the support rod 3 from shaking. When it is necessary to retract the support rod 3, press the movable block 20 and push the movable block 20, so that the top block 17 slides out of the tooth groove of gear 13 under the action of the connecting column 26. The contracted spring 19 will reset, thereby pulling gear 13, so as to quickly retract the support rod 3 into the bottom of the base 1.

[0034] Reference Figure 1 , Figure 5 and Figure 6A threaded tube 4 is fixedly connected to the outer periphery of the spring tube 2. A support column 28 is fixedly connected to the outer periphery of the threaded tube 4. A dust cover 9 is rotatably connected to the outer periphery of the support column 28. A threaded sleeve 5 is threadedly connected to the outer periphery of the threaded tube 4. A push-pull plate 6 is rotatably connected to the outer periphery of the threaded sleeve 5. A connecting assembly is installed between the push-pull plate 6 and the dust cover 9. The connecting assembly includes a positioning block 8 and a connecting rod 7. The positioning block 8 is fixedly connected to the outer side of the dust cover 9. A sliding groove 16 is opened in the middle of the positioning block 8. One end of the connecting rod 7 is rotatably connected to the outer side of the push-pull plate 6. The other end of the connecting rod 7 is rotatably connected to a sliding rod 27. The sliding rod 27 is slidably connected to the middle of the sliding groove 16. A notch 29 is provided on the edge of the dust cover 9. After the meeting, the threaded sleeve 5 is turned around the outer circumference of the threaded tube 4, thereby pushing the push-pull plate 6, which in turn moves the connecting rod 7. This allows the connecting rod 7 to drive the sliding rod 27 to slide in the sliding groove 16 in the positioning block 8, so that the dust cover 9 can rotate around the outer circumference of the support column 28. This allows the upper and lower dust covers 9 to merge together and protect the microphone 10, preventing dust from falling into the microphone 10 and causing blockage or damage, thus extending the service life of the microphone 10. At the same time, when using the microphone, turning the threaded sleeve 5 in the opposite direction can open the dust cover 9. Additionally, the notch 29 prevents the two dust covers 9 from obstructing each other during rotation.

[0035] Working principle: First, when placing the microphone, turning the screw block 14 drives the round rod 18 to rotate, which in turn drives the gear 13 to rotate. Since the gear 13 meshes with the top block 17, the gear 2 15 can rotate with the gear 13. This allows the gear 2 15 to drive the support rod 3 to rotate out from the bottom of the base 1 through the rotating rod 12, thereby increasing the support points of the base 1. This makes the microphone more stable and reduces the possibility of the microphone falling over due to collisions, preventing the microphone from being damaged by falling and collisions.

[0036] Tightening the threaded sleeve 5 moves it around the outer periphery of the threaded tube 4, causing the push-pull plate 6 around the outer periphery of the threaded sleeve 5 to push or pull the connecting rod 7. When the connecting rod 7 is pulled, it will cause the sliding rod 27 to slide in the middle of the positioning block 8, so that the positioning block 8 can drive the dust cover 9 to rotate around the outer periphery of the support column 28, thereby allowing the two dust covers 9 to be combined or unfolded. In this way, when the microphone is not used for a long time, the dust cover 9 can be used to cover the microphone 10 to prevent dust from falling into the microphone 10 and causing blockage and damage.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
