Description

Technical Field

[0001] This utility model relates to the field of audio equipment accessories technology, specifically a desktop cantilever microphone stand. Background Technology

[0002] In today's era of information dissemination and communication, microphones, as key devices for sound acquisition, play an irreplaceable and vital role. From professional recording studios to everyday online live streaming, from classroom teaching in schools to large-scale conference speeches, microphones are ubiquitous. They convert sound signals into electrical signals, thereby enabling sound amplification, recording, and transmission. Whether singers use them to showcase their beautiful voices, broadcasters use them to interact with fans, or speakers use them to convey important information, microphones ensure that sound is captured and transmitted clearly and accurately, greatly expanding the scope and effect of sound propagation and improving the quality and efficiency of information exchange.

[0003] Microphone stands, as supporting equipment for microphones, are equally important. They provide stable support for the microphone, ensuring it maintains the correct position and angle during use for optimal sound pickup. At the same time, microphone stands free up the user's hands, allowing for greater freedom in performances, speeches, or other activities.

[0004] However, existing microphone stands have revealed several problems in practical use. Firstly, they have significant limitations in terms of space utilization. Common desktop microphone stands, while convenient to use on a desk, often occupy a large amount of space. For users with limited desk space, such as creators who frequently need to stream or record on small workbenches, these stands further compress the available workspace, making the desk appear cluttered and impacting work efficiency. While floor-standing microphone stands offer better stability, placing them on the floor can make the surrounding space feel cramped. Floor-standing stands occupy valuable floor space, easily obstructing movement and potentially causing accidental bumps that could damage the microphone.

[0005] Secondly, consumers of different heights have significantly different needs for microphone height. Using microphone stands of the same height obviously cannot meet everyone's needs. For taller users, a microphone height that is too low will require them to bend over to speak, leading to fatigue during prolonged use; while for shorter users, a microphone that is too high will result in poor sound pickup and be extremely inconvenient to use. However, most existing microphone stands are difficult to adjust in terms of height. Some stands have complex height adjustment mechanisms that require users to spend considerable time and effort operating them, and may even require additional tools; while others do not have height adjustment functionality at all, which greatly limits their applicable users and usage scenarios.

[0006] Furthermore, microphone usage habits vary greatly among different groups. Some people, such as singers or broadcasters who pursue the ultimate sound quality, prefer to sing or speak very close to the microphone to better capture sound details and obtain a clearer, fuller sound. Others, to maintain a good image and posture, usually choose to keep a certain distance from the microphone. However, existing microphone stands are not convenient for adjusting the distance between the microphone and the user. Most stands only allow for simple position adjustments and cannot precisely meet the personalized distance needs of different people. This often forces users to constantly adjust their position or posture to find a suitable sound pickup point, which not only affects the user experience but may also affect sound quality.

[0007] Traditional microphone stands often suffer from problems such as inconvenient adjustment, large space occupation, or insufficient stability, affecting the user experience. Therefore, there is a need for a microphone stand that is simple in structure, easy to install, and convenient to adjust. Utility Model Content

Detailed Implementation

[0036] 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.

[0037] Please see Figure 1-7 This utility model provides a technical solution:

[0038] A desktop cantilever microphone stand includes a fixed base 1, a support arm 2 fixedly connected to one side of the fixed base 1, a microphone external connector 3 at the end of the support arm 2, and multiple sets of movable connecting arms. The microphone external connector 3 is equipped with a microphone external bolt 25 corresponding to the microphone. The fixed base 1 can be fixed to one side of a desktop, and the microphone can be fixedly mounted at the microphone external bolt 25. By adjusting the multiple connecting arms in the support arm 2, the microphone can be adjusted to different heights and distances. It is convenient to use, suitable for various needs, occupies little space, is securely fixed, and the microphone is not easily tipped over or damaged.

[0039] Furthermore, the fixed base 1 includes an inverted bracket 4, a first screw handle 5, a fixing bolt 6, and a top block 7. The inverted bracket 4 is placed on one side of the desktop, with the desktop positioned at the inverted opening. The lower part of the inverted bracket 4 is threadedly connected to the fixing bolt 6. The end of the fixing bolt 6 facing away from the inverted bracket 4 is coaxially connected to the first screw handle 5. The end of the fixing bolt 6 inside the inverted bracket 4 is provided with the top block 7, and the end of the top block 7 facing away from the fixing bolt 6 abuts against the lower side of the desktop. An anti-slip pad 8 is provided on the top block 7. It is recommended that the anti-slip pad 8 be made of a rubber material with a certain degree of elasticity. When it is necessary to fix the bracket on the desktop, first place the inverted bracket 4 on one side of the desktop, so that the desktop is positioned at the inverted opening. Then, rotate the first screw handle 5. Since the first screw handle 5 is coaxially connected to the fixing bolt 6, and the fixing bolt 6 is threadedly connected to the lower part of the inverted bracket 4, rotating the first screw handle 5 will drive the fixing bolt 6 to rotate. During rotation, the fixing bolt 6 moves along the thread direction into the U-shaped fixing bracket 4, thereby pushing the top block 7 against the underside of the desktop. The anti-slip pad 8 on the top block 7 increases the friction with the desktop, ensuring a secure fixation while preventing damage to the desktop. In this way, the bracket is firmly fixed to the edge of the desktop without taking up too much desktop space.

[0040] Furthermore, the support arm 2 includes a support arm base 9, a first connecting arm 10, a second connecting arm 11, a third connecting arm 12, and a fourth connecting arm 13.

The third connecting arm 12 is provided at one end of the second connecting arm 11 away from the first connecting arm 10. The second connecting arm 11 and the third connecting arm 12 are rotatably connected through a second joint. The fourth connecting arm 13 is provided at one end of the third connecting arm 12 away from the second connecting arm 11. The third connecting arm 12 and the fourth connecting arm 13 are hinged together through a third joint. A microphone external connector 14 is provided at one end of the fourth connecting arm 13 away from the third connecting arm 12. When angle adjustment is required, the second connecting arm 11 can rotate around the first rotating shaft 16 within the rotating shaft hole 15, thereby changing the angle with the first connecting arm 10. The connecting sleeve 17 of the second joint and the second rotating shaft 18 cooperate with each other, allowing the third connecting arm 12 to rotate relative to the second connecting arm 11, achieving angle adjustment in another direction. The first hinge 19, the second hinge 20, and the hinge shaft 21 of the third joint allow the fourth connecting arm 13 to hinge and rotate relative to the third connecting arm 12. Through the coordinated action of these three joints, the support arm 2 can achieve multi-directional angle adjustment, thereby adjusting the height and horizontal position of the microphone external part 3 to meet the needs of different users for the spatial position of the microphone.

[0041] Furthermore, the first joint includes a pivot hole 15 and a first rotating shaft 16.

The connecting sleeve 17 is perpendicular to the second connecting arm 11, and the direction of the connecting sleeve 17 is opposite to the direction of the first rotating shaft 16. One end of the third connecting arm 12 is machined into a second rotating shaft 18 corresponding to the connecting sleeve 17. The second rotating shaft 18 is inserted into the connecting sleeve 17 and coaxially connected with the connecting sleeve 17.

[0043] Furthermore, the third joint includes a first hinge 19, a second hinge 20, and a hinge shaft 21.

The rotating pan / tilt head 24 is coaxially connected to the microphone external connector 14 via the male ring 27. A spherical cavity 28 is formed at the end of the rotating pan / tilt head 24 facing away from the microphone external connector 14. A rotating ball 29 is slidably engaged within the spherical cavity 28. A connecting rod 30 is fixedly connected to one side of the rotating ball 29. The end of the connecting rod 30 facing away from the rotating ball 29 is fixedly connected to the microphone external connector bolt 25. The tightening / loosening assembly 26 is installed on the rotating pan / tilt head 24. The rotating pan / tilt head 24 of the microphone external connector 3 and the microphone external connector 14 are coaxially connected via the male ring 27 and the female groove 23, allowing the rotating pan / tilt head 24 to rotate coaxially relative to the microphone external connector 14. The spherical cavity 28 inside the rotating gimbal 24 is slidably engaged with the rotating ball 29. The rotating ball 29 is fixedly connected to the microphone external bolt 25 via the connecting rod 30, which allows the microphone external bolt 25 to rotate relative to the rotating gimbal 24 at multiple angles.

[0046] Furthermore, the rotating gimbal 24 is divided into a first gimbal component 31 and a second gimbal component 32. The tensioning assembly 26 includes a second screw handle 33 and a fastening bolt 34.

When it is necessary to fix the microphone, it can be adjusted through the tensioning assembly 26. The second screw handle 33 of the tensioning assembly 26 is threadedly connected to the fastening bolt 34. Rotating the second screw handle 33 can make the fastening bolt 34 apply pressure to the first gimbal component 31 and the second gimbal component 32, thereby adjusting the tightness of the rotating ball 29 in the spherical cavity 28, and fixing the microphone angle.

[0047] Furthermore, the microphone external bolt 25 includes a base bolt post 36 and a sleeve bolt member 37. The end of the connecting rod 30 facing away from the rotating ball 29 is coaxially connected to the base bolt post 36. The end of the base bolt post 36 facing away from the connecting rod 30 is machined with a first external thread. The sleeve bolt member 37 is fitted onto the base bolt post 36. The inner side of the sleeve bolt member 37 is machined with an internal thread corresponding to the first external thread, and the outer side of the sleeve bolt member 37 is machined with a second external thread. The sleeve bolt member 37 is threadedly connected to the base bolt post 36. An anti-slip screw ring 38 is provided on one side of the first external thread and the second external thread. The first external thread and the second external thread have different sizes. Through different thread designs, it can be adapted to various models of microphones, making it convenient for users to install and use.

[0048] Working Principle: This device achieves stable fixation and flexible adjustment through the precise cooperation of its various components. When installing the bracket on a desktop, place the C-shaped fixing bracket 4 on one side of the desktop, with the desktop positioned within the C-shaped opening. Then, rotate the first turning handle 5. Since it is coaxially connected to the fixing bolt 6, and the fixing bolt 6 and the lower part of the C-shaped fixing bracket 4 are threaded together, the rotation of the first turning handle 5 will cause the fixing bolt 6 to move into the C-shaped fixing bracket 4 under the action of the threads, thereby pushing the top block 7 tightly against the underside of the desktop. The anti-slip pad 8 on the top block 7 increases friction, making the bracket more securely fixed, and also prevents damage to the desktop. In this way, the bracket is firmly fixed to the edge of the desktop without taking up too much desktop space. The support arm 2 consists of a support arm base 9, a first connecting arm 10, a second connecting arm 11, a third connecting arm 12, and a fourth connecting arm 13, all connected by specific joints. The first joint consists of a pivot hole 15 and a first rotating shaft 16. The second connecting arm 11 is coaxially connected to the pivot hole 15 on the first connecting arm 10 via the first rotating shaft 16, allowing the second connecting arm 11 to rotate around the first rotating shaft 16 and achieve angle adjustment. The connecting sleeve 17 of the second joint cooperates with the second rotating shaft 18. The second connecting arm 11 is inserted into and coaxially connected to the second rotating shaft 18 of the third connecting arm 12 via the connecting sleeve 17, allowing for rotational adjustment in another direction. The third joint, through the first hinge 19, the second hinge 20, and the hinge shaft 21, allows the third connecting arm 12 and the fourth connecting arm 13 to achieve hinged rotation. These three joints work together to enable the support arm 2 to be adjusted in multiple directions and angles, thereby adjusting the height and horizontal position of the microphone external part 3 to meet the various needs of different users for microphone position. The rotating gimbal 24 is coaxially connected to the microphone external part connector 14 through the sliding engagement of the male ring 27 and the female groove 23, achieving relative rotation. The spherical cavity 28 inside the rotating gimbal 24 is slidably engaged with the rotating ball 29. The rotating ball 29 is fixed to the microphone external bolt 25 via the connecting rod 30, allowing the microphone external bolt 25 to rotate at multiple angles. To fix the microphone angle, the tightening component 26 can be operated, and the second turning handle 33 can be rotated. It is threadedly connected to the fastening bolt 34, thereby applying pressure to the first gimbal component 31 and the second gimbal component 32, adjusting the tightness of the rotating ball 29 within the spherical cavity, and thus fixing the microphone angle. Furthermore, the microphone external bolt 25 consists of a base bolt post 36 and a sleeve bolt component 37. Different thread designs can accommodate various microphone models, facilitating user installation and use.
