Description

Technical Field

[0001] This utility model belongs to the field of microphone technology, specifically relating to a conference microphone with a folding and storage structure. Background Technology

[0002] A microphone, also known as a transducer or microphone, is an energy conversion device that converts sound signals into electrical signals. In meetings, because people's voices are relatively soft, a conference microphone is needed to amplify the sound so that it can be heard more clearly.

[0003] Existing microphones mainly consist of a speaker and a microphone. The microphone receives sound, which is then converted by an audio amplification circuit and played synchronously by the speaker to increase the volume of speech in the conference room. However, traditional conference microphones (such as gooseneck and desktop microphones) usually adopt an integrated fixed structure, and the microphone pole, base and other components cannot be folded. After the meeting, the microphone takes up a lot of storage space. If it needs to be carried to a temporary venue (such as a hotel conference room or an outdoor forum), it is easy to be damaged by the collision of the protruding parts. Moreover, it is difficult to pack into a regular briefcase or equipment case, which increases transportation costs and inconvenience. Utility Model Content

[0004] The purpose of this invention is to provide a conference microphone with a foldable storage structure 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 with a folding and storage structure, comprising:

[0006] A base is provided to provide a stable place for the microphone. The top of the base is provided with a U-shaped bracket for mounting the microphone, and the microphone is rotatably connected to the U-shaped bracket.

[0007] A folding assembly, located within a U-shaped frame, is used to enable the microphone to rotate and fold. By controlling the rotation angle of the microphone through the folding assembly, the stability of the folding and storage action and the fixed adjustment of the microphone angle during use are ensured.

[0008] A protective mesh cover is provided on top of the microphone, and the protective mesh cover and the microphone are connected in a stable manner by a fixing component. This not only provides effective protection for the microphone's pickup components, but also ensures that the protective mesh cover is not easy to loosen or fall off during use.

[0009] The suction cups are arranged in several groups and are all located inside the base. When the base is placed on a smooth tabletop, atmospheric pressure is used to make the suction cups adhere tightly to the tabletop, preventing the microphone from being knocked over.

[0010] Preferably, the folding assembly includes a rotating ball, which is provided in two sets and respectively connected to the bottom two ends of the microphone. The top two ends of the U-shaped frame are connected to rotating sleeves. One end of the rotating ball is rotatably connected to the rotating sleeve, so that the microphone can achieve flexible angle adjustment by means of the rotating ball rolling in the rotating sleeve.

[0011] Preferably, both ends of the top of the U-shaped frame are provided with threaded cylinders and the threaded cylinders are connected to hand-tightening bolts. By tightening the hand-tightening bolts, the ends of the bolts abut against the rotating ball, thereby fixing the folding angle of the microphone.

[0012] Preferably, the fixing component includes arc-shaped blocks, and the arc-shaped blocks are provided in two sets and respectively disposed inside the top of the microphone. The top of the microphone is symmetrically provided with two sets of sliding grooves, and the two sets of arc-shaped blocks are slidably connected in the two sets of sliding grooves respectively.

[0013] Preferably, a spring is connected inside the sliding groove, and one end of the spring is connected to the arc-shaped block.

[0014] Preferably, the microphone has an arc-shaped mounting groove at the top, and one end of the arc-shaped block protrudes into the arc-shaped mounting groove.

[0015] Preferably, the bottom of the protective mesh cover is connected to an installation ring, and the installation ring has two sets of symmetrical locking holes. After the installation ring at the bottom of the protective mesh cover is inserted into the arc-shaped installation groove, the arc-shaped block is locked into the locking hole, thereby fixing the protective mesh cover to the microphone.

[0016] Preferably, a support frame is connected between the base and the U-shaped frame.

[0017] Preferably, the base has a slot and a suction cup frame is slidably connected in the slot. Several suction cups are connected to the bottom of the suction cup frame. A threaded rod is rotatably connected to the base through a bearing. The middle part of the suction cup frame is connected to the threaded rod through a nut.

[0018] Preferably, the base has a guide groove, the suction cup holder is slidably connected to the guide groove via a guide block, and two sets of guide rods are symmetrically connected inside the base, with the suction cup holder slidably sleeved on the guide rods.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) The rotating balls at both ends of the microphone are connected to the rotating sleeve by the folding component, so that the microphone can roll in the rotating sleeve with the help of the rotating balls to achieve flexible angle adjustment. The microphone pole can rotate and fold flexibly relative to the U-shaped frame, which greatly reduces the overall volume of the device in the storage state and reduces the storage space occupied.

[0021] (2) Based on the rotation characteristics of the folding component (the rotating ball can roll freely in the rotating sleeve), users can flexibly adjust the microphone angle according to the needs of the scenario. The combination design of the hand-tightening bolt and the threaded cylinder can fix the rotating ball by the bolt after adjustment, ensuring that the microphone can be used stably in different forms. It can adapt to diverse scenarios without additional accessories, improving the practicality of use.

[0022] (3) The protective mesh cover is fixed to the outside of the microphone pickup head by the "elastic engagement of the arc block and the card hole". It can directly block the impact of external bumps on the pickup components and reduce noise generation. Its fine mesh can not only intercept dust and prevent impurities from entering the microphone and affecting the sound quality, but also effectively block the saliva that may splash out when speaking, preventing saliva from adhering to the pickup head and causing pollution. The protective mesh cover can be disassembled and cleaned, which can further reduce maintenance costs. In addition, when folded for storage, the microphone fits with the U-shaped frame, and the microphone pickup head is wrapped inside the protective mesh cover, reducing the risk of squeezing and deformation during transportation or storage, structurally reducing equipment wear and tear and extending service life.

[0023] (4) In scenarios such as meetings, the desktop may vibrate slightly due to people walking or objects moving, or the microphone may shift due to accidental touch. The suction cup tightly adheres to the desktop through atmospheric pressure and is compatible with a variety of smooth surfaces. Whether it is a glass desktop, a wooden lacquered desktop, or a marble tabletop in a hotel venue, the suction cup can adapt to different smooth surfaces by adjusting the suction strength. It can be placed stably without additional fixing tools, enhancing the device's scene adaptability, effectively resisting external impacts, preventing the microphone from tipping over or sliding, ensuring a stable pickup position, and reducing the problem of sound interruption caused by device displacement.

[0033] 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.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0035] This utility model provides, for example Figure 1-8 The conference microphone shown includes a folding and storage structure, comprising a microphone 2, a U-shaped frame 3, a folding assembly, a protective mesh cover 4, a base 1, a stand 15, and a suction cup 17. The folding assembly is used to realize the rotational connection and angle adjustment between the microphone 2 and the U-shaped frame 3. The protective mesh cover 4 is used to protect the pickup component of the microphone 2. The base 1 is used to provide a supporting foundation for the entire microphone 2 device. The stand 15 is used to connect the base 1 and the U-shaped frame 3 to enhance the overall structural stability.

[0036] The folding assembly includes a rotating ball 5, which has two sets and is respectively connected to the bottom ends of the microphone 2. The other end of the rotating ball 5 is rotatably connected to the rotating sleeves 6 at the top ends of the U-shaped frame 3, thereby enabling the microphone 2 to rotate flexibly relative to the U-shaped frame 3 to meet the requirements of folding and multi-angle adjustment.

[0037] The suction cups 17 are provided in several groups and are all located inside the base 1. When the base 1 is placed on a smooth table, atmospheric pressure is used to make the suction cups 17 adhere tightly to the table, preventing the microphone 2 from being knocked over.

[0038] The U-shaped frame 3 is equipped with a threaded cylinder 7, through which a hand-tightening bolt 8 passes. After passing through the threaded cylinder 7, the end of the hand-tightening bolt 8 can extend to the inside of the rotating sleeve 6 and abut against the side of the rotating ball 5. When it is necessary to fix the rotation angle of the microphone 2, the hand-tightening bolt 8 is rotated clockwise. Under the action of the threaded engagement, the hand-tightening bolt 8 moves along the threaded cylinder 7 towards the rotating ball 5 until its end is in close contact with the side of the rotating ball 5 and applies pressure. At this time, the rotating ball 5 is subjected to the pressure of the hand-tightening bolt 8 and the friction of the inner wall of the rotating sleeve 6, and can no longer roll. The rotation angle of the microphone 2 is fixed. When it is necessary to adjust the rotation angle of the microphone 2, the hand-tightening bolt 8 is rotated counterclockwise. The hand-tightening bolt 8 moves along the threaded cylinder 7 away from the rotating ball 5, and its end is no longer in contact with the side of the rotating ball 5. The rotating ball 5 is no longer constrained by pressure and can roll freely in the rotating sleeve 6, thereby unlocking the rotation angle of the microphone 2 so that the microphone 2 can be readjusted to the required angle.

[0039] The microphone 2 has an arc-shaped mounting groove 12 at its top, with symmetrically distributed sliding grooves 10 inside. A spring 11 and an arc-shaped block 9 are located within each sliding groove 10. One end of the spring 11 is fixed to the bottom of the sliding groove 10, and the other end is connected to the arc-shaped block 9. In its natural state, the arc-shaped block 9 partially protrudes into the arc-shaped mounting groove 12. The bottom of the protective mesh cover 4 has a mounting ring 13 that matches the arc-shaped mounting groove 12. The outer side of the mounting ring 13 has a locking hole 14 corresponding to the arc-shaped block 9. During installation, the mounting ring 13 presses against the arc-shaped block 9 to contract it and compress the spring 11. After reaching its position, the spring 11 rebounds, pushing the arc-shaped block 9 into the locking hole 14 for fixation. During disassembly, external force pulls the protective mesh cover 4, causing the locking hole 14 to compress the arc-shaped block 9, allowing the mounting ring 13 to be pulled out.

[0040] The base 1 adopts a flat design with a low center of gravity and is equipped with an anti-slip pad on the bottom. When placed, the bottom surface is in full contact with the table. The anti-slip pad increases friction and reduces the risk of the device sliding or tipping over due to collision. The stand 15 is a metal rod or a high-strength plastic rod. Its lower end is fixedly connected to the center of the base 1, and its upper end is fixedly connected to the center of the bottom of the U-shaped frame 3. It transfers the weight of the microphone 2 and the U-shaped frame 3 to the base 1 through its rigid structure. The U-shaped frame 3 has a symmetrical structure. The two ends are connected to rotating sleeves 6 to support the microphone 2, and the middle is connected to the stand 15 to ensure that the weight of the microphone 2 is evenly distributed and to prevent the overall structure from tilting due to excessive force on one side.

[0041] The protective mesh cover 4 is made of metal, which can effectively protect the microphone head of the microphone 2, prevent it from contaminating the microphone 2's pickup components, and ensure the normal transmission of sound signals without affecting the microphone 2's pickup effect.

[0042] The base 1 has a slot 19, and a suction cup frame 16 is slidably connected within the slot 19. Several suction cups 17 are connected to the bottom of the suction cup frame 16. A threaded rod 18 is rotatably connected to the base 1 via a bearing. The middle part of the suction cup frame 16 is connected to the threaded rod 18 via a nut. The base 1 has a guide groove 20, and the suction cup frame 16 is slidably connected to the guide groove 20 via a guide block 21. Two sets of guide rods 22 are symmetrically connected within the base 1, and the suction cup frame 16 is slidably sleeved on the guide rods 22. The suction cups 17 inside the base 1 are made of soft silicone and have a bowl-shaped structure (diameter 3-4cm). The edges are designed with a 0.5mm thick inclined lip. This thick inclined lip structure allows it to tightly fit the gaps in the tabletop under pressure, improving sealing performance. The suction cups 17 are connected by a "large"... The "air pressure adsorption" mechanism achieves the fixing effect. Specifically, when it is necessary to use the suction cup 17 to fix the microphone 2, rotate the threaded rod 18. Under the action of the threaded transmission, the suction cup frame 16 slides down along the guide groove 20, causing the suction cup 17 to contact the smooth table. As the suction cup frame 16 continues to move down, the air between the suction cup 17 and the table is gradually discharged. The internal air pressure is lower than the external atmospheric pressure. The external atmospheric pressure presses the suction cup 17 tightly against the table, forming a stable adsorption. If it is necessary to release the fixation, rotate the threaded rod 18 in the opposite direction. The suction cup frame 16 moves upward, the suction cup 17 separates from the table, and air enters the inside of the suction cup 17, releasing the adsorption state. Alternatively, use both hands to pull the stand 15 to drive the suction cup 17 in the base 1 to detach from the adsorption on the table. Finally, reset the suction cup 17 and move it into the slot 19 for storage.

[0043] The guide block 21 is embedded in the guide groove 20 and maintains a sliding fit. It can restrict the lateral displacement of the guide block 21 through the side wall of the guide groove 20, and together with the guide rod 22, force the suction cup frame 16 to move only along the vertical direction of the guide groove 20 and the guide rod 22, ensuring that the suction cup 17 always contacts the table in a horizontal state, avoiding uneven force on the suction surface and air leakage gaps caused by tilting.

[0044] The conference microphone 2 with a folding and storage structure comprises a rotating ball 5 and a rotating sleeve 6. One end of the rotating ball 5 is fixedly connected to the bottom two ends of the microphone 2, and the other end is embedded in the rotating sleeve 6 at the top two ends of the U-shaped frame 3. The inner wall of the rotating sleeve 6 is arc-shaped, which fits perfectly with the curved surface of the rotating ball 5 and leaves sufficient clearance for movement. When folding is required, push the microphone 2 rod, and the rotating ball 5 will roll along the inner wall of the rotating sleeve 6, causing the microphone 2 to rotate relative to the U-shaped frame 3 until the microphone 2 rod is parallel to the U-shaped frame 3, completing the folding state. To unfold for use, pull the microphone 2 rod in the opposite direction, and the rotating ball 5 will roll in the opposite direction, allowing the microphone 2 to be adjusted to the desired angle.

[0045] A threaded cylinder 7 is located next to the rotating sleeve 6 of the U-shaped frame 3. A hand-tightening bolt 8 passes through the threaded cylinder 7, with the end of the bolt facing the side of the rotating ball 5. When the microphone 2 is adjusted to the folding angle, the hand-tightening bolt 8 is rotated clockwise. The bolt will move along the threaded cylinder 7 toward the rotating ball 5 until its end is tightly pressed against the curved surface of the rotating ball 5. At this time, the rotating ball 5 is subjected to the pressure of the bolt and the friction of the inner wall of the rotating sleeve 6, and can no longer roll freely. The angle of the microphone 2 is then firmly fixed. If it needs to be adjusted again, the hand-tightening bolt 8 is rotated counterclockwise to disengage it from the rotating ball 5, and the rotating ball 5 returns to its free-rolling state.

[0046] When installing the protective mesh cover 4, the microphone 2 has an arc-shaped mounting groove 12 at its top, with two symmetrically distributed sliding grooves 10 (the sliding grooves 10 communicate with the arc-shaped mounting groove 12) inside. Each sliding groove 10 contains a spring 11 and an arc-shaped block 9. Under normal conditions, the spring 11 will push a part of the arc-shaped block 9 out of the sliding groove 10 and into the arc-shaped mounting groove 12 (the protruding part of the arc-shaped block 9 is hemispherical). The bottom of the protective mesh cover 4 has a mounting ring 13 that matches the arc-shaped mounting groove 12. The outer side of the ring has a locking hole 14 corresponding to the arc-shaped block 9 (the locking hole 14 is a hemispherical groove). During installation, the mounting ring 13 at the bottom of the protective mesh cover 4 is aligned with the arc-shaped mounting groove 12 and inserted. The edge of the ring will first contact the protruding part of the arc-shaped block 9 and squeeze it. After the arc-shaped block 9 is subjected to force, it retracts into the sliding groove 10 and compresses the spring 11 at the same time until the mounting ring 13 is fully inserted into the arc-shaped mounting groove 12. At this time, the position of the arc-shaped block 9 and the locking hole 14 are exactly aligned. The spring 11 is no longer squeezed and rebounds, pushing the protruding part of the arc-shaped block 9 into the locking hole 14 to form a "locking". The protective mesh cover 4 is then fixed on the microphone 2 to protect the microphone 2's pickup head.

[0047] If the protective net cover 4 needs to be removed, apply a certain external force to pull the protective net cover 4 outward. The installation ring 13 will cause the inner wall of the locking hole 14 to squeeze the protruding part of the arc block 9. The arc block 9 will be pressed into the sliding groove 10 again and the spring 11 will be compressed. When the arc block 9 is completely disengaged from the locking hole 14, the ring can be pulled out from the arc mounting groove 12 to complete the disassembly.

[0048] 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.
