Description

Technical Field

[0001] This utility model relates to the field of audio pivot technology, and more specifically, to a pivot for audio equipment. Background Technology

[0002] With the continuous advancement of audio technology, people's pursuit of high-fidelity and immersive audio experiences is increasing. For example, surround sound systems have gradually evolved from the traditional 5.1 channels to more complex audio formats such as 7.1 channels and Dolby Atmos. This requires audio equipment to more accurately position the direction of sound propagation, ensuring that the sound from each channel reaches the listener's ears precisely, thereby creating a realistic three-dimensional spatial sound effect. This high demand for sound precision has driven the development of audio pivot structures towards high-precision adjustment.

[0003] Existing speaker pivots are becoming increasingly diverse due to the evolving use of modern audio equipment, extending beyond fixed indoor locations to include outdoor gatherings, car audio systems, and portable Bluetooth speakers. Different scenarios demand different adjustments to the speaker's angle and position. Furthermore, during use, speakers can be affected by various external forces, such as accidental collisions, wind, or contact with other objects, causing movement and displacement. This can easily disrupt the frequency response and phase characteristics of the sound, leading to sound quality degradation and affecting the original speaker setup.

[0004] Therefore, a pivot for audio equipment is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pivot for audio equipment to solve the problems mentioned in the background art.

A double-wrap support is provided on the right side of the single-wrap support, and the fixed support is installed on the upper end face of the double-wrap support. A sliding cavity is provided at the center of the fixed support, and a rotating shaft is installed in the inner cavity of the single-wrap support. Bosses are provided at the upper and lower ends of the rear end face of the fixed support, and mounting holes are provided at the four corners of the fixed support.

[0008] Preferably, one side of the single-package support is inserted into the center of the inner cavity of the double-package support, and the single-package support is connected to the double-package support through the pivot.

[0009] Preferably, the front end face of the double-walled support abuts against the rear end faces of the two sets of protrusions respectively, and the guide shaft is fixed in the double-walled support by being riveted to the first fixing plate. When the guide shaft is inserted into the sliding cavity, the second fixing plate abuts against one side of the front end face of the fixed support.

[0010] Preferably, both sides of the guide shaft and the outer surface of the card block are flat, and both the guide shaft and the outer surface of the card block achieve linear guiding movement along the inner surface of the sliding cavity.

[0021] 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.

[0022] Example 1

[0023] As attached Figures 1 to 5 The pivot shown includes a single-wrap support 1, a fixed support 3, a threaded rod 11 and a crescent-shaped limiting mechanism 13. A double-wrap support 2 is provided on the right side of the single-wrap support 1. The fixed support 3 is installed on the upper end face of the double-wrap support 2. A sliding cavity 21 is provided at the center of the fixed support 3. A rotating shaft 4 is installed in the inner cavity of the single-wrap support 1. A boss 5 is provided at the upper and lower ends of the rear end face of the fixed support 3, and mounting holes 6 are provided at the four corners of the fixed support 3.

[0024] A guide shaft 7 is installed on the left side of the inner cavity of the slide cavity 21. A first fixing plate 8 is installed on the rear end face of the guide shaft 7. A spring piece 9 is provided on the front end face of the first fixing plate 8. A second fixing plate 10 is installed on the front end face of the guide shaft 7. A threaded rod 11 is installed on the right side of the inner cavity of the slide cavity 21. A locking block 12 is installed on the front end face of the threaded rod 11. A nut 15 is installed on the outer surface of the end of the threaded rod 11 away from the locking block 12. A crescent-shaped limiting mechanism 13 is installed on the front end face of the locking block 12. A contact pad 14 is installed between the locking block 12 and the crescent-shaped limiting mechanism 13.

[0025] The single-walled support frame 1 and the double-walled support frame 2 together form the main structural framework for adjusting the speaker angle. Their combination provides a stable support platform for the speaker, allowing it to change angle within a certain range. The fixed support frame 3, through the mounting holes 6 at the four corners, uses bolts and other fasteners to firmly install the entire pivot structure onto the speaker base, providing a stable foundation platform for other components. The sliding cavity 21 at its center provides a precise guide track for the movement of the guide shaft 7, ensuring that the guide shaft 7 maintains linear motion during forward and backward movement, thus guaranteeing the accuracy and stability of the speaker during forward and backward adjustment. The boss 5 on the rear end face not only helps prevent the double-walled support frame 2 from wobbling during forward and backward movement, but also allows the guide shaft 4, installed inside the single-walled support frame 1, to act as a connecting hub between the single-walled support frame 1 and the double-walled support frame 2, enabling relative rotation between them and thus realizing the speaker's vertical angle adjustment function. The forward and backward movement of the guide shaft 7 within the sliding cavity 21 realizes the speaker's forward and backward position adjustment function. The first fixing plate 8 and the second fixing plate 10 are located at the two ends of the guide shaft 7, respectively, serving to fix and position the guide shaft 7, ensuring... It will not deviate during movement, which helps the guide shaft 7 to be riveted to the double-walled support 2. The spring 9 is set on the front end face of the first fixed plate 8. Its main function is to control the friction between the guide shaft 7 and the double-walled support 2. Appropriate friction allows the user to feel comfortable and accurately control the adjustment range when adjusting the audio. The threaded rod 11 cooperates with the locking block 12 to realize the limiting function of the guide shaft 7 by moving in the slide cavity 21. The crescent limiting mechanism 13 is installed on the front end face of the locking block 12. By engaging the nut 15 with the threaded rod 11, the entire limiting structure can be fixed in a suitable position in the slide cavity 21, ensuring the durability and stability of the limiting effect. It can effectively limit the position of the guide shaft 7 in the slide cavity 21 and prevent it from being over-displaced during the forward and backward guiding movement, ensuring the stability of the audio position and helping the audio to accurately produce stable sound. The contact pad 14 can not only buffer the impact force between the locking block 12 and other components, but also increase the friction force and further improve the reliability of the limiting.

[0026] Example 2

[0027] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details:

[0028] In a preferred embodiment, one side of the single-pack support 1 is inserted into the center of the inner cavity of the double-pack support 2, and the single-pack support 1 is connected to the double-pack support 2 through a rotating shaft 4. Furthermore, the design of the single-pack support 1 being inserted into the center of the inner cavity of the double-pack support 2 and connected through the rotating shaft 4 makes the vertical angle adjustment more precise, and the speaker rotates with a stable central axis as a reference.

[0029] In a preferred embodiment, the front end face of the double-walled support 2 abuts against the rear end faces of the two sets of bosses 5 respectively. The guide shaft 7 is fixed by being riveted to the double-walled support 2 through the first fixing plate 8. When the guide shaft 7 is inserted into the sliding cavity 21, the second fixing plate 10 abuts against one side of the front end face of the fixed support 3. Furthermore, the guide shaft 7 is fixed by being riveted to the double-walled support 2 through the first fixing plate 8, and when inserted into the sliding cavity 21, the second fixing plate 10 abuts against one side of the front end face of the fixed support 3, so that the guide shaft 7 and the double-walled support 2 form a relatively stable whole.

[0030] In a preferred embodiment, both sides of the outer surfaces of the guide shaft 7 and the locking block 12 are flat. The outer surfaces of the guide shaft 7 and the locking block 12 achieve linear guiding movement along the inner surface of the sliding cavity 21. When the double-walled support 2 moves with the guide shaft 7, it moves linearly along the rear end faces of the two sets of bosses 5. Furthermore, the flatness of the outer surfaces of the guide shaft 7 and the locking block 12 and their ability to achieve linear guiding movement along the inner surface of the sliding cavity 21 allow them to move strictly along a predetermined straight trajectory during movement. When adjusting the front and rear position of the speaker, the user can precisely control the distance and direction of movement. Each push or pull of the double-walled support 2 to move the guide shaft 7 can achieve accurate position changes, thereby precisely positioning the speaker in the required front and rear position. Even if the speaker is subjected to a slight collision from the side or vibration caused by its own speaker sound, the double-walled support 2 is not prone to left or right deviation or up and down swaying due to the blocking effect of the bosses 5, thus ensuring that it moves smoothly along the designed front and rear direction, laying the foundation for precise adjustment of the speaker position.

[0031] In a preferred embodiment, when the threaded rod 11 is inserted into the sliding cavity 21 along with the locking block 12, the contact pad 14, in conjunction with the crescent-shaped limiting mechanism 13, abuts against the other side of the front end face of the fixed support 3. The contact pad 14 is made of silicone. Furthermore, through the buffering and friction adjustment effect of the contact pad 14, the crescent-shaped limiting mechanism 13 can abut against the fixed support 3 more precisely, thereby achieving a more stable limiting of the guide shaft 7. The silicone material fills the tiny gaps that may exist between the components, making the limiting contact tighter and more stable.

[0032] In a preferred embodiment, the inner cavity of the crescent-shaped limiting mechanism 13 has space for the second fixing plate 10 to abut against. After the threaded rod 11 passes into the sliding cavity 21, it engages with the nut 15. Furthermore, the user can move the guide shaft 7 to a specific position as needed, and then tighten the nut 15 to fix the threaded rod 11 in place with the locking block 12 and the crescent-shaped limiting mechanism 13 connected thereto, thereby firmly restricting the guide shaft 7 to the desired position, ensuring that the speaker is always accurately in the adjusted position, and guaranteeing the accuracy and stability of the sound propagation direction.

[0033] The working process of this utility model is as follows: First, the fixed support frame 3 is connected to the base of the speaker through four sets of mounting holes 6. When it is necessary to adjust the vertical angle of the speaker, the user manually applies external force to the single-enclosed support frame 1 or the double-enclosed support frame 2. Since the single-enclosed support frame 1 is connected to the double-enclosed support frame 2 through the rotating shaft 4, and the single-enclosed support frame 1 is inserted into the center of the inner cavity of the double-enclosed support frame 2, the two can rotate relative to each other around the rotating shaft 4, thereby realizing the vertical adjustment of the speaker angle and meeting the needs of different scenarios for the vertical direction of sound propagation. When adjusting the front and rear position of the speaker, external force is applied to the double-enclosed support frame 2. Since the guide shaft 7 is riveted to the double-enclosed support frame 2 through the first fixing plate 8, the external force is applied to the double-enclosed support frame 2. Inside the frame 2, the guide shaft 7 and the outer surfaces of the locking block 12 are flat and can move linearly along the inner surface of the sliding cavity 21. When the double-walled support frame 2 is moved by force, it will drive the guide shaft 7 to move back and forth in the sliding cavity 21. At the same time, the double-walled support frame 2 will move linearly along the rear end face of the two sets of protrusions 5 on the rear end face of the fixed support frame 3 to ensure the stability and directionality of its movement trajectory and prevent deviation or shaking. During this process, the spring piece 9 on the front end face of the first fixed plate 8 will contact the inside of the double-walled support frame 2 to control the friction between the guide shaft 7 and the double-walled support frame 2. The appropriate friction allows the user to feel moderate resistance when pushing the double-walled support frame 2.

[0034] After the guide shaft 7 moves to the desired position, the threaded rod 11 is inserted into the sliding cavity 21 along with the locking block 12. At this time, the silicone contact pad 14 will be linked with the crescent-shaped limiting mechanism 13 to abut against the other side of the front end face of the fixed support 3. At the same time, the second fixing plate 10 abuts against the inner cavity of the crescent-shaped limiting mechanism 13. Since the contact pad 14 has a certain elasticity and buffering performance, on the one hand, it can buffer the impact force between the crescent-shaped limiting mechanism 13 and the fixed support 3 during the abutment process, protecting the surface of the component from hard collision damage. On the other hand, it can increase the friction force to ensure the tight connection between the crescent-shaped limiting mechanism 13 and the fixed support 3. By engaging the nut 15 with the threaded rod 11, two sets of such limiting structures are added to limit the guide shaft 7 at the front and back, so that the entire limiting structure is fixed, thereby firmly restricting the guide shaft 7 to the current position and preventing it from being displaced due to external interference. The above is the working principle of this kind of pivot used in audio equipment.
