Technical Field

[0001] This application belongs to the field of speaker stands, and more specifically, relates to a speaker stand and a stand kit. Background Technology

[0002] Speaker stands, as auxiliary equipment specifically designed to fix and support audio devices, play an indispensable role in creating a high-quality audio environment. To maximize the sound experience, many speaker stands are equipped with height adjustment functions. This feature allows users to flexibly adjust the placement height of the speakers according to the venue layout and listening needs, thereby ensuring that the sound can be propagated to the audience area in the most ideal way.

[0003] However, despite the wide variety of speaker stands on the market, most products still have significant shortcomings in terms of ease of height adjustment. Traditional adjustment methods often rely on manual knobs, clips, or screws, forcing users to repeatedly loosen and tighten them during adjustment, making speaker height adjustment inconvenient.

[0060] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0061] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0063] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0064] Currently, there are various types of speaker stands, such as floor stands, desktop stands, ceiling stands, and wall-mounted stands. Most speaker stands have height adjustment functions, allowing the height of the speaker 6 to be adjusted. Adjusting the height of the speaker 6 can optimize sound propagation, adapt to the acoustic needs of different scenarios, and consider both spatial layout and ease of use. For example, adjusting the height of the speaker 6 to be level with the listener's ears can reduce sound wave reflection interference. Similarly, adjusting the speaker 6 to be as close as possible to the television 7 allows for better matching and a better viewing and listening experience. Furthermore, raising the speaker 6 can prevent furniture from obstructing the sound wave path.

[0065] Currently, the height adjustment methods for speakers include snap-on / pin-type, screw-locking, cylinder-lifting, and motor-driven methods. Among these, the screw-lifting method typically requires rotation, thus its applicability is relatively limited, and it's less suitable for suspended or wall-mounted speaker stands with fixed foundations. Cylinder-lifting and motor-driven methods usually require pneumatic or electrical power, further restricting their use. Therefore, snap-on / pin-type speaker stands are currently the most common. When adjusting the height of a snap-on / pin-type speaker stand, the process usually involves first loosening the snap or pin, forcefully supporting the speaker to adjust it to the appropriate height, and then tightening the snap or pin to lock the speaker in place. This is not only time-consuming and laborious but also significantly reduces the flexibility and efficiency of adjustment, undoubtedly causing inconvenience for users.

[0066] To address the aforementioned problems with speaker stands, this application provides a speaker stand; please refer to [link / reference]. Figures 1 to 7 The speaker stand provided in the embodiments of this application will now be described. The speaker stand includes:

[0067] First frame 1;

[0068] Second frame 2; Second frame 2 is used to install speaker 6, and second frame 2 can move relative to first frame 1 in a first direction;

[0069] Elastic telescopic member 31; the elastic telescopic direction of the elastic telescopic member 31 is parallel to the first direction, and the elastic telescopic member 31 is connected between the first frame 1 and the second frame 2 to provide load-bearing capacity to the second frame 2;

[0070] Friction element 32; Friction element 32 is configured to provide adjustable friction force for the extension and retraction of elastic telescopic element 31 to adjust the load-bearing capacity of elastic telescopic element 31 on the second frame 2.

[0071] The first frame 1 serves as the fixed foundation for the entire speaker bracket, typically connected to the ground, mounting surface, or other installation location. It provides stability to the overall structure and usually possesses sufficient strength to support the entire bracket system and the speaker 6. The structure of the first frame 1 can vary depending on the speaker bracket type. For example, for a floor-standing bracket, the first frame 1 can consist of one or more uprights, fixed to the base with bolts. Similarly, for a wall-mounted bracket, the first frame 1 can be a mounting plate with screw holes, secured to the mounting surface with screws. In this way, the first frame 1 is usually matched to the intended installation location of the speaker bracket, thus providing a stable foundation for its installation.

[0072] The second frame 2 primarily supports the speaker 6, meaning the speaker 6 is mounted on the second frame 2. The second frame 2 can be equipped with mounting parts corresponding to the speaker 6. For example, for a long, narrow speaker 6, a horizontal mounting plate or multiple horizontally arranged mounting brackets are needed; similarly, for a bottom-supported speaker 6, corresponding support brackets are needed; and for a top-suspended speaker 6, corresponding hanging brackets are needed. A protective cover 21 can be installed on the second frame 2 to protect it and improve its aesthetics.

[0073] To achieve height adjustment of the speaker 6, in this example, the second frame 2 can move relative to the first frame 1 in a first direction. This first direction is typically the vertical direction after the speaker bracket is correctly installed, but it can also be tilted relative to the vertical direction. Both methods allow for height adjustment of the second frame 2 relative to the first frame 1. For example… Figure 3 The Z direction shown is the first direction of this embodiment. The relative movement between the second frame 2 and the first frame 1 can be achieved using a sliding rail structure, with up-and-down sliding via a guide rail and roller / slider system; or a nested sleeve structure; the second frame 2 and the first frame 1 are mutually nested tubular structures. Furthermore, if necessary, the first frame 1 and the second frame 2 can also be connected solely by the elastic telescopic member 31. The speaker 6 is mounted on the second frame 2, and its height can be adjusted when the second frame 2 is adjusted relative to the first frame 1.

[0074] The elastic telescopic component 31 is an elastic and extendable element connected between the first frame 1 and the second frame 2. The elastic telescopic component 31 extends in a direction parallel to the first direction, meaning that the direction of extension of the elastic telescopic component 31 is consistent with the direction of movement of the second frame 2 relative to the first frame 1. For example, if the second frame 2 moves vertically, then the elastic telescopic component 31 should also extend in a vertical direction. In this way, the elastic telescopic component 31 can provide force for the relative movement of the second frame 2 and the first frame 1. Specifically, the elastic telescopic component 31 can counteract part or all of the weight of the speaker 6 through the reaction force generated by its elastic deformation, so that when adjusting the height, the user only needs to overcome friction rather than the entire weight, achieving effortless operation.

[0075] The elastic telescopic component 31 can be made of components such as coil springs, gas springs, or constant force springs. In particular, a constant force spring is a special type of spring that can provide a relatively constant elastic force within a certain deformation range. This elastic force does not change significantly with increasing deformation. Thus, within a given compression or tension range, it can provide an almost constant supporting force for the second frame 2. When the supporting force of the constant force spring is equal to the total weight of the second frame 2 and its components such as the speakers 6, the second frame 2 can be stopped at any position within the given compression or tension range of the constant force spring. However, since the weight of each speaker 6 is different, for non-dedicated speaker stands, it cannot be guaranteed that the elastic force provided by the constant force spring is exactly equal to the total weight of the second frame 2 and its components such as the speakers 6.

[0076] The impact bracket in this embodiment solves this problem. The speaker bracket in this embodiment also includes a friction element 32, an elastic telescopic element 31, and the friction element 32 forming a load-bearing assembly 3. This provides adjustable friction for the extension and retraction of the elastic telescopic element 31. The size of the friction element 32 can be adjusted by changing the pressure, contact area, and roughness of the contact between the friction element 32 and the elastic telescopic element 31. Adjusting the pressure between the friction element 32 and the elastic telescopic element 31 is the simplest method. The direction of friction is always opposite to the direction of the object's movement. Adjustable friction allows adjustment of the supporting force output by the constant force spring, thereby adjusting the load-bearing capacity of the elastic telescopic element 31 on the second frame 2.

[0077] by Figure 2 For example, if the weight of the speaker 6 is too large, the elastic telescopic member 31 is insufficient to support the total weight of the second frame 2 and the speaker 6 on it, and the speaker 6 will tend to descend. At this time, the direction of the frictional force is opposite to the descending trend, that is, the frictional force is an upward force. At this time, the sum of the frictional force and the elastic force of the elastic telescopic member 31 can be equal to the total weight of the second frame 2 and the speaker 6 on it, so that the second frame 2 stays at the expected height.

[0078] If the weight of the speaker 6 is too small, the elastic force of the elastic telescopic member 31 will exceed the total weight of the second frame 2 and the speaker 6 on it. The speaker 6 will have an upward tendency. At this time, the direction of the friction force is opposite to the upward tendency, that is, the friction force is a downward force. At this time, the sum of the friction force and the elastic force of the elastic telescopic member 31 can also be equal to the total weight of the second frame 2 and the speaker 6 on it, so that the second frame 2 stays at the expected height.

[0079] As can be seen, the friction element 32 can provide an adjustable additional friction force to the elastic telescopic element 31 to adjust the output load-bearing capacity of the elastic telescopic element 31, so as to match it with the total weight of the second frame 2 and the speaker 6 on it. When the weight of the speaker 6 is different, the elastic telescopic element 31 can automatically adjust the support force to maintain a balanced state, thereby improving the versatility of the speaker bracket.

[0080] It is important to emphasize that the friction force provided by the friction member 32 in this embodiment is different from the locking force. It does not lock the relative position between the second frame 2 and the first frame 1. When it is necessary to adjust the position of the second frame 2 and the speaker 6 on it, it is not necessary to loosen the friction member 32; the adjustment can be made directly. Generally, the friction force of the friction member 32 only needs to be adjusted when the total weight on the second frame 2 changes, for example, when a new speaker 6 is installed or the speaker 6 is replaced.

[0081] It should also be noted that the presence of friction element 32 allows for adjustment of the load-bearing capacity of elastic telescopic element 31 on the second frame 2. Therefore, elastic telescopic element 31 does not necessarily need to be a constant-force spring; using a regular spring is also feasible. When the second frame 2 is stationary, friction element 32 and elastic telescopic element 31 are also relatively stationary. Within the range of maximum friction, since the size of friction element 32 automatically adjusts according to the magnitude of the external force, when the second frame 2 is adjusted to a new position and comes to rest, although the output elasticity of a regular spring will change, within an allowable range, the friction provided by friction element 32 can automatically adjust to match it, thus keeping the second frame 2 stationary in the new position. In other words, due to the adaptive nature of the friction provided by friction element 32, elastic telescopic element 31 in this embodiment does not necessarily need to be a constant-force spring; even using an elastic telescopic element 31 whose output elasticity changes with deformation is feasible.

[0082] Please see Figures 3 to 7 In some embodiments of this application, the elastic telescopic member 31 includes a constant force spring, which includes a coiled portion 311 and an extension portion 312 connected to each other.

[0083] The curled part 311 is rotatably disposed on one of the first frame 1 and the second frame 2, and the extension part 312 is connected to the other of the first frame 1 and the second frame 2.

[0084] The friction member 32 abuts against the curled portion 311, and the abutment pressure applied by the friction member 32 to the curled portion 311 is adjustable to provide adjustable friction force.

[0085] In this embodiment, the elastic telescopic member 31 in the supporting component 3 includes a constant force spring, which can maintain a relatively constant force during extension and contraction. This characteristic makes it very suitable for applications requiring stable support. This embodiment utilizes this characteristic in an audio speaker bracket. The elastic telescopic member 31 includes a coiled portion 311 and an extension portion 312 connected to each other. The coiled portion 311 is the coiled part of the constant force spring, which is typically a coiled metal part. The extension portion 312 is the portion extending from the coiled portion 311. The coiled portion 311 is rotatably disposed on one of the first frame 1 and the second frame 2, allowing it to rotate, thereby enabling the extension and contraction of the extension portion 312 while providing a constant elastic force. The extension portion 312 is connected to the other of the first frame 1 and the second frame 2. Specifically, if the coiled portion 311 is disposed on the first frame 1, the extension portion 312 is connected to the second frame 2, and vice versa. The curling part 311 can provide a constant elastic force, and the extension part 312 is responsible for transmitting the elastic force provided by the curling part 311 to the second frame 2, thereby providing load-bearing capacity to the second frame 2.

[0086] Friction element 32 is in direct contact with the coiled portion 311 of the constant force spring, and friction is generated by applying adjustable pressure. This design allows the user to adjust the magnitude of the friction force according to the weight of the speaker 6 and the required positional stability. When the difference between the elastic force provided by the constant force spring and the total weight of the second frame 2 and the speaker 6 on it is large, the pressure of friction element 32 on the coiled portion 311 can be increased, thereby increasing the friction force. This friction force compensates for the difference, ensuring sufficient support and positional stability. When the difference between the elastic force provided by the constant force spring and the total weight of the second frame 2 and the speaker 6 on it is small, the pressure of friction element 32 on the coiled portion 311 can be decreased, thereby decreasing the friction force. The friction force is kept sufficient to compensate for the difference, and the lower friction force makes position adjustment easier and more flexible. The coiled portion 311 is rotatable, and friction element 32 abuts against it, which generally maintains a relatively large contact area and relatively high contact stability.

[0087] In summary, in this embodiment, the constant force spring provides a relatively stable and continuous load-bearing force during the movement of the second frame 2, ensuring reliable support for the speaker 6 mounted on the second frame 2 in different positions. This is crucial for protecting the speaker 6 and preventing damage caused by shaking or unstable support. The friction force is altered by adjusting the contact pressure of the adjustable friction element 32 against the coiled portion 311, thereby adjusting the load-bearing force of the elastic telescopic element 31 on the second frame 2, greatly improving the adaptability of the bracket. In practical use, users can flexibly adjust the friction force according to factors such as the weight of the speaker 6 and the requirements of the installation environment, allowing the bracket to better match different usage scenarios.

[0088] Please see Figures 5 to 7 In some embodiments of this application, the speaker bracket includes a mounting shaft 34 and an adjusting nut 33; the mounting shaft is disposed on the first frame 1 or the second frame 2, the curled part 311 is sleeved on the mounting shaft 34, and the curled part 311 can rotate relative to the mounting shaft 34.

[0089] The friction element 32 is sleeved on the mounting shaft 34 and can move axially along the mounting shaft 34. The adjusting nut 33 abuts against the end of the friction element 32 away from the curled part 311. The adjusting nut 33 is threadedly connected to the mounting shaft 34 so as to adjust the abutting pressure applied by the adjusting nut 33 to the friction element 32 by rotating the adjusting nut 33, thereby adjusting the abutting pressure applied by the friction element 32 to the curled part 311.

[0090] In this embodiment, the mounting shaft 34 and the adjusting nut 33 are mounted on the first frame 1 or the second frame 2. The mounting shaft 34 provides a stable axis for the entire mechanical structure and serves as the basic support for the installation and operation of the coiled part 311 and the friction element 32. The adjusting nut 33 is the key operating component of the entire friction adjustment mechanism. It cooperates with the friction element 32 to adjust the friction pressure and friction force of the friction element 32.

[0091] The coiled portion 311 of the constant force spring is mounted on the mounting shaft 34 in a sleeve manner. This design gives the coiled portion 311 the ability to rotate around the mounting shaft 34. When the second frame 2 moves relative to the first frame 1 in a first direction, the extension portion 312 of the constant force spring is stretched or retracted due to the movement of the second frame 2. At the same time, the coiled portion 311 rotates accordingly on the mounting shaft 34. For example, if the second frame 2 moves upward, the extension portion 312 is stretched, and the coiled portion 311 will rotate around the mounting shaft 34. Through this rotation, the elastic potential energy stored inside the constant force spring is converted into an upward supporting force on the second frame 2, thereby providing a stable load-bearing force for the speaker 6 mounted on the second frame 2. The coiled part 311 of the constant force spring is sleeved on the mounting shaft 34. If the coiled part 311 is to be mounted on the first frame 1, the mounting shaft 34 and the corresponding adjusting nut 33 are set on the first frame 1. Conversely, if the coiled part 311 is to be mounted on the second frame 2, the mounting shaft 34 and the corresponding adjusting nut 33 are set on the second frame 2.

[0092] Friction element 32 is also fitted onto mounting shaft 34, but its movement differs from that of the coiled part 311. It can move along the axial direction of mounting shaft 34, allowing friction element 32 to move closer to or further away from coiled part 311 as needed, thereby applying different contact pressures to coiled part 311. This axial movement design provides the necessary conditions for precise adjustment of friction force via adjusting nut 33, and is an important component of the entire friction force adjustment system.

[0093] The adjusting nut 33 is threadedly connected to the mounting shaft 34, which is the core mechanism for achieving precise adjustment. One end of the adjusting nut 33 abuts against the friction element 32. When the user rotates the adjusting nut 33, due to the characteristics of the thread, the adjusting nut 33 will move axially along the mounting shaft 34. For example, when the adjusting nut 33 is rotated clockwise, the adjusting nut 33 moves towards the friction element 32, thereby squeezing the friction element 32 and increasing the abutting pressure of the friction element 32 against the coiled part 311. At this time, the frictional force on the coiled part 311 during rotation increases accordingly, which will hinder the extension and retraction of the constant force spring, thereby changing the load-bearing capacity of the elastic telescopic element 31 on the second frame 2. Conversely, when the adjusting nut 33 is rotated counterclockwise, the adjusting nut 33 moves away from the friction element 32, reducing the abutting pressure on the friction element 32. The frictional force when the coiled part 311 rotates decreases, making the extension and retraction of the elastic telescopic element 31 easier, and the load-bearing capacity on the second frame 2 will be adjusted accordingly.

[0094] like Figure 5 and Figure 6In the illustrated embodiment, a bushing 35 is fitted onto the mounting shaft 34, and the coiled portion 311 of the constant force spring is fitted onto the bushing 35 to ensure stable rotation of the coiled portion 311. The friction element 32 comprises two pieces, respectively disposed at both ends of the coiled portion 311, serving a clamping function. The inner hole of the friction element 32 is a waist-shaped hole, corresponding to the waist-shaped cross-section of the mounting shaft 34, which prevents the friction element 32 from rotating with the coiled portion 311, thus providing stable friction. Since the friction force adjustment of the friction element 32 is typically only performed during the installation and replacement of the speaker 6, an outer retaining ring 36 is fitted over the mounting shaft 34 to protect the adjusting nut 333 and prevent accidental contact. The outer retaining ring 36 can be fixed to the mounting shaft 34 with screws.

[0095] like Figure 7 In the embodiment shown, a fixing plate 37 is provided on the first frame 1, and the extension 312 is connected to the first frame 1 through the fixing plate 37 to facilitate the installation of the extension 312.

[0096] Please see Figures 8 to 13 In some embodiments of this application, the speaker bracket includes a locking member 41, which is disposed on one side of the curled portion 311. The locking member 41 can move along a second direction, which is the direction in which the locking member 41 approaches or moves away from the curled portion 311.

[0097] The locking member 41 has a first position and a second position in the second direction;

[0098] In the first position, the locking member 41 abuts against the side of the curled portion 311 to lock the curled portion 311;

[0099] In the second position, the locking member 41 releases the coiled portion 311 to release the locking of the coiled portion 311.

[0100] In the preceding embodiments, it was emphasized that the function of the friction member 32 was to compensate for the load-bearing capacity of the elastic telescopic member 31, keeping the second frame 2 balanced in a certain position, rather than locking it to a certain position. In this embodiment, to achieve locking of the second frame 2, the speaker bracket is equipped with a locking member 41. The locking member 41 is positioned on one side of the constant force spring coil portion 311, providing a basis for subsequent locking operations on the coil portion 311. The locking member 41 has the ability to move along a specific direction, which is defined as the second direction. It is worth noting that the second direction refers to the direction in which the locking member 41 can move closer to or further away from the coil portion 311, for example, Figure 8 The X direction shown is the second direction of this embodiment. This design allows the locking member 41 to establish different contact states with the curled part 311 by moving, thereby realizing the locking and unlocking functions of the curled part 311.

[0101] During its movement along the second direction, the locking member 41 has two key positional states, defined as the first position and the second position. When the locking member 41 moves to the first position, it presses firmly against the side of the coiled portion 311, restricting its rotation. Once the coiled portion 311 of the constant force spring is locked, its extension 312 can no longer freely extend or retract with the movement of the second frame 2. For example, when the speaker bracket is adjusted to a suitable height and the user wants to fix this height, the locking member 41 is moved to the first position, pressing firmly against the coiled portion 311. In this way, the second frame 2 can no longer move freely due to the action of the constant force spring, thereby locking the position of the speaker 6 and preventing changes in the height of the speaker 6 due to accidental contact or other external forces.

[0102] When the locking member 41 is in the second position, the tight contact between it and the coiled part 311 is released, i.e., the coiled part 311 is unloaded. At this time, the coiled part 311 is no longer restricted by the locking member 41 and can rotate freely. This means that the extension 312 of the constant force spring can again stretch or retract normally as the second frame 2 moves in the first direction. For example, when the user needs to readjust the height of the speaker 6, moving the locking member 41 to the second position unlocks the coiled part 311, and the second frame 2 can then move freely in the first direction according to the user's operation under the action of the constant force spring, making it convenient for the user to adjust the speaker 6 to a new position.

[0103] This embodiment includes a locking element 41, adding extra functionality and practicality to the speaker bracket. From a stability perspective, in the first position, the locking element 41 effectively locks the coiled portion 311, thereby fixing the position of the second frame 2 and greatly enhancing the stability of the speaker bracket in a specific position. This is particularly important for scenarios where the speaker 6 needs to be fixed at a certain height for extended use, such as conference rooms or performance stages. It prevents the position of the speaker 6 from changing due to vibrations caused by people walking, vibrations of the equipment itself, or other external interference factors, thus ensuring that the speaker 6 is always in optimal working condition. From a flexibility perspective, in the second position, the locking element 41 releases the lock on the coiled portion 311, allowing the user to easily adjust the position of the speaker 6. The user can freely adjust the height of the speaker 6 according to different acoustic needs, changes in venue layout, and other factors. For example, in a home theater scenario, the user may need to flexibly adjust the height of the speaker 6 according to different viewing angles to obtain a better sound experience; in this case, the unlocking function of the locking element 41 provides great convenience. This design also extends the lifespan of the speaker stand because the locking coil section 311 prevents the constant force spring from frequently extending and contracting unnecessarily, reducing spring fatigue. At the same time, this embodiment also enhances the user experience, allowing users to easily and quickly switch the speaker stand's operating state according to actual needs, achieving both stable support and flexible position adjustment to meet diverse usage scenarios.

[0104] Please see Figures 8 to 13 In some embodiments of this application, the speaker bracket includes a swing rod 42 and a locking shaft 43; the swing rod 42 is hinged to the first frame 1 or the second frame 2 via a first hinge shaft 47, and the first hinge shaft 47 and the curled part 311 are located on the same one of the first frame 1 and the second frame 2; the locking shaft 43 is disposed on the swing rod 42 so that the locking shaft 43 can rotate around the first hinge shaft 47.

[0105] The locking member 41 is provided with a drive elongated hole 411, the locking shaft 43 is inserted into the drive elongated hole 411 and can move along the drive elongated hole 411, and the curled part 311 is located on the side of the locking member 41 away from the first hinge shaft 47.

[0106] The drive hole 411 gradually approaches the first hinge shaft 47 in the first rotational direction of the locking shaft 43, so that the locking shaft 43 rotates in the first rotational direction to drive the locking member 41 to press against the coiled part 311.

[0107] The drive hole 411 gradually moves away from the first hinge shaft 47 in the second rotation direction of the locking shaft 43, so that the locking shaft 43 rotates in the second rotation direction to drive the locking member 41 to release the curled part 311. The second rotation direction is the opposite of the first rotation direction.

[0108] In this embodiment, a swing rod 42 and a locking shaft 43 are added based on the above embodiment. The swing rod 42 and the locking shaft 43 are used to tighten and loosen the locking member 41 against the curled part 311, thereby realizing the position locking and unlocking of the second frame 2.

[0109] Specifically, the swing rod 42 and the second frame 2 are hinged together via a first hinge pin 47. This hinge allows the swing rod 42 to swing around the first hinge pin 47. A locking pin 43 is mounted on the swing rod 42. Since the swing rod 42 can rotate around the first hinge pin 47, the locking pin 43 also has the ability to rotate around the first hinge pin 47. The first hinge pin 47 and the curled part 311 are located on the same part of the first frame 1 and the second frame 2. That is, if the curled part 311 is located on the first frame 1, then the first hinge pin 47 and the swing rod 42 are also located on the first frame 1; if the curled part 311 is located on the second frame 2, then the first hinge pin 47 and the swing rod 42 are also located on the second frame 2. This allows the swing rod 42 and the locking pin 43 thereon to stably control the locking member 41 to lock and release the curled part 311.

[0110] The locking member 41 has a drive elongated hole 411 machined on it. The locking shaft 43 passes through the drive elongated hole 411 and can move freely within it, allowing the locking shaft 43 to drive the locking member 41 through the drive elongated hole 411. When the locking shaft 43 rotates along the first rotation direction, the drive elongated hole 411 gradually approaches the first hinge shaft 47. Therefore, during the rotation of the locking shaft 43 along the first rotation direction, the locking member 41 can be pushed away from the first hinge shaft 47. The curled portion 311 is located on the side of the locking member 41 away from the first hinge shaft 47, meaning that the locking member 41 can be pushed towards the curled portion 311. As the locking shaft 43 continues to rotate, the locking member 41 will continuously approach the curled portion 311, eventually pressing tightly against the curled portion 311, thereby locking the curled portion 311. This design utilizes the rotational motion of the locking shaft 43 and the special shape of the drive elongated hole 411 to cleverly convert the rotational motion into the linear motion of the locking member 41, thereby achieving effective locking of the curled part 311.

[0111] The second rotation direction is the opposite of the first rotation direction. The driving elongated hole 411 gradually approaches the first hinge shaft 47 in the first rotation direction of the locking shaft 43, and correspondingly, the driving elongated hole 411 gradually moves away from the first hinge shaft 47 in the second rotation direction of the locking shaft 43. When the locking shaft 43 rotates in the second rotation direction, the movement of the locking shaft 43 will cause the locking member 41 to move away from the curled portion 311. As the locking shaft 43 rotates, the locking member 41 will gradually disengage from the curled portion 311, thereby releasing the lock on the curled portion 311.

[0112] like Figure 8 and Figure 9 In the illustrated embodiment, the counterclockwise direction α is the first rotation direction, and the clockwise direction β is the second rotation direction, such as... Figure 12 As shown, the rocker arm rotates counterclockwise, causing the locking assembly 4 to enter the locking state; as Figure 13 As shown, the lever rotates clockwise, causing the locking assembly 4 to enter the unlocked state.

[0113] Please see Figure 9 In some embodiments of this application, the speaker 6 further includes a guide shaft 44. The guide shaft 44 and the coiled portion 311 of the constant force spring are located on the same frame as either the first frame 1 or the second frame 2. This ensures that the guide shaft 44 and the coiled portion 311 are relatively stable, so that the guide shaft 44 can provide a guiding effect on the locking member 41, allowing it to stably move closer to or away from the coiled portion 311. If the coiled portion 311 is installed on the first frame 1, then the guide shaft 44 will also be installed at the corresponding position on the first frame 1. If the coiled portion 311 is installed on the second frame 2, then the guide shaft 44 will also be installed at the corresponding position on the second frame 2.

[0114] A guide hole 412 is machined into the locking member 41. The guide hole 412 is oriented along a second direction. The second direction refers to the direction in which the locking member 41 approaches or moves away from the curled portion 311. Figure 9 In the illustrated embodiment, the second direction is the left-right direction. The guide shaft 44 is inserted into the guide elongated hole 412. The guide shaft 44 plays a role in restricting and guiding within the guide elongated hole 412, which runs along the second direction. The guide shaft 44 slides within it, ensuring that the locking member 41 moves stably along the second direction and preventing offset or shaking in other directions.

[0115] The number of guide shafts 44 and guide holes 412 can both be multiple. For example, multiple guide shafts 44 can be provided for the same guide hole 412, and multiple guide holes 412 can be provided on the same locking member 41, thereby improving the stability of the guide. Figure 9 In the embodiment shown, two parallel guide holes 412 are provided on the same locking member 41, and two guide shafts 44 are provided in the same guide hole 412, thereby ensuring the stability of the movement of the locking member 41.

[0116] Please see Figure 10 In some embodiments of this application, the speaker bracket further includes a stop member 46, which is disposed on the side of the curled portion 311 away from the locking member 41, so as to stop the curled portion 311 when the locking member 41 is pressed against the curled portion 311.

[0117] This embodiment adds a stopper 46 to the above embodiments. The stopper 46 is disposed on the side of the constant force spring coiled portion 311 opposite to the locking member 41. When the locking member 41 functions and presses tightly against the coiled portion 311, the stopper 46 blocks it from the other side of the coiled portion 311. Specifically, when the locking member 41 applies pressure causing the coiled portion 311 to tend to move towards the stopper 46, the stopper 46 can withstand this pressure, preventing the coiled portion 311 from moving excessively, thereby maintaining the stable state of the constant force spring.

[0118] Please see Figure 8 and Figure 10 In some embodiments of this application, the elastic telescopic member 31 includes a plurality of constant force springs, among which a first constant force spring and a second constant force spring are spaced apart along the second direction.

[0119] The speaker bracket includes multiple locking members 41 and multiple locking shafts 43. Among the multiple locking members 41, there is a first locking member 41 and a second locking member 41. The coiled portion 311 of the first constant force spring is located on the side of the first locking member 41 away from the first hinge shaft 47, and the coiled portion 311 of the second constant force spring is located on the side of the second locking member 41 away from the first hinge shaft 47.

[0120] The plurality of locking shafts 43 include a first locking shaft 43 and a second locking shaft 43. The first locking shaft 43 is disposed at the first end of the swing rod 42, the second locking shaft 43 is disposed at the second end of the swing rod 42, and the first hinge shaft 47 is located between the first end and the second end.

[0121] The first locking shaft 43 is inserted into the drive elongated hole 411 of the first locking member 41, and the second locking shaft 43 is inserted into the drive elongated hole 411 of the second locking member 41.

[0122] The drive elongated holes 411 of the first locking member 41 and the second locking member 41 gradually approach the first hinge shaft 47 in the first rotation direction, and the drive elongated holes 411 of the first locking member 41 and the second locking member 41 gradually move away from the first hinge shaft 47 in the second rotation direction.

[0123] Although a single constant-force spring can provide the force to support the speaker 6, in this embodiment, the elastic telescopic component 31 of the speaker bracket is not a single constant-force spring, but rather composed of multiple constant-force springs. The arrangement of multiple constant-force springs means that when the bracket provides elastic support, it can exert force from multiple parts in a coordinated manner, which can improve the stability and load-bearing capacity of the support compared to a single constant-force spring.

[0124] Because there are multiple constant force springs, the speaker bracket is equipped with multiple locking elements 41 and locking shafts 43. Specifically, in this embodiment, the speaker bracket includes a first constant force spring and a second constant force spring, which are spaced apart along the second direction to facilitate driving by the same swing arm 42. Correspondingly, the speaker bracket includes a first locking element 41 and a second locking element 41. The coiled portion 311 of the first constant force spring is located on the side of the first locking element 41 away from the first hinge shaft 47, and the coiled portion 311 of the second constant force spring is located on the side of the second locking element 41 away from the first hinge shaft 47. This arrangement allows the coiled portion 311 of each constant force spring to be locked or unlocked by the corresponding locking element 41, that is, the first locking element 41 can lock the coiled portion 311 of the first constant force spring, and the second locking element 41 can lock the coiled portion 311 of the second constant force spring.

[0125] Among the multiple locking shafts 43, there is a first locking shaft 43 and a second locking shaft 43. The first locking shaft 43 is installed at the first end of the swing rod 42, and the second locking shaft 43 is installed at the second end of the swing rod 42. The first hinge shaft 47 is located between the first end and the second end of the swing rod 42. The swing rod 42 is hinged to the second frame 2 through the first hinge shaft 47. This structural design allows the swing rod 42 to rotate around the first hinge shaft 47. Since the first locking shaft 43 and the second locking shaft 43 are respectively located at both ends of the swing rod 42, when the swing rod 42 rotates, the locking shafts 43 at both ends will rotate around the first hinge shaft 47, laying the foundation for the subsequent movement of the locking member 41 through the drive elongated hole 411.

[0126] The first locking shaft 43 is inserted into the drive elongated hole 411 of the first locking member 41, and the second locking shaft 43 is inserted into the drive elongated hole 411 of the second locking member 41. The existence of the drive elongated hole 411 provides a specific trajectory for the movement of the locking shaft 43. When the swing rod 42 drives the locking shaft 43 to rotate around the first hinge shaft 47, the locking shaft 43 moves within the drive elongated hole 411, thereby pushing or pulling the corresponding locking member 41. Thus, the locking and unlocking of the first and second locking members 41 can be controlled simultaneously by the same swing rod 42.

[0127] In the first rotational direction, the drive elongated holes 411 of both the first locking member 41 and the second locking member 41 gradually approach the first hinge shaft 47; in the second rotational direction, the drive elongated holes 411 of both the first locking member 41 and the second locking member 41 gradually move away from the first hinge shaft 47. Since both the first locking shaft 43 and the second locking shaft 43 are located on the swing rod 42, their rotational directions are the same. When the swing arm 42 rotates in the first rotation direction, due to the characteristic that the driving elongated hole 411 gradually approaches the first hinge shaft 47, the first locking shaft 43 will push the first locking member 41 to move towards the coiled portion 311 of the first constant force spring. At the same time, the second locking shaft 43 will push the second locking member 41 to move towards the coiled portion 311 of the second constant force spring, thereby achieving synchronous locking of the first constant force spring and the second constant force spring. When the swing arm 42 rotates in the second rotation direction, due to the characteristic that the driving elongated hole 411 gradually moves away from the first hinge shaft 47, the first locking shaft 43 will pull the first locking member 41 away from the coiled portion 311 of the first constant force spring. At the same time, the second locking shaft 43 will pull the second locking member 41 away from the coiled portion 311 of the second constant force spring, thereby achieving synchronous unlocking of the first constant force spring and the second constant force spring.

[0128] Therefore, this embodiment can use the same swing lever 42 to synchronously control the locking and unlocking of the first constant force spring and the second constant force spring, thereby greatly simplifying the structure and operation.

[0129] Please see Figure 9 and Figure 10 In some embodiments of this application, a handwheel 45 is also provided on the locking shaft 43. The handwheel 45 and the locking shaft 43 are threadedly connected. When the handwheel 45 and the locking shaft 43 are rotated and gradually tightened, the end faces of the handwheel 45 and the locking shaft 43 will slowly press against the frame, thereby maintaining the position of the locking member 41. For example, when the locking member 41 locks the constant force spring, the handwheel 45 can be tightened to prevent the locking member 41 from shifting and causing locking failure. Similarly, when the locking member 41 leaves the constant force spring, the handwheel 45 can also be tightened to prevent the locking member 41 from shifting. If the locking member 41 shifts and contacts the constant force spring, it will affect the rotation of the constant force spring coiled portion 311.

[0130] Please see Figure 14 , Figure 15 as well as Figure 4 In some embodiments of this application, the first frame 1 includes a first through hole extending in a first direction, and the second frame 2 includes a first rod 22 extending in the first direction. The first rod 22 is inserted into the first through hole to restrict the movement of the second frame 2 relative to the first frame 1 in the first direction. The first rod 22 includes a first groove 221 extending in the first direction, a curled portion 311 connected to the second frame 2, and an extension portion 312 disposed in the first groove 221 and connected to the first frame 1.

[0131] In this embodiment, the first frame 1 has a first through hole, the orientation of which is consistent with the previously mentioned first direction, extending along the first direction. This means it provides a specific track for the movement of the second frame 2. The second frame 2 is equipped with a first rod 22 extending along the first direction. The function of the first rod 22 is to cooperate with the first through hole of the first frame 1. When the first rod 22 is inserted into the first through hole, a guiding and restricting structure is formed. Since the first rod 22 can only move along the first direction within the first through hole, it effectively restricts the direction of movement of the second frame 2 relative to the first frame 1, allowing linear movement in the first direction and preventing the second frame 2 from swaying or deviating in other directions, thus ensuring the stability and accuracy of the movement of the second frame 2. For example, if the first direction is vertical, after the first rod 22 is inserted into the first through hole, the second frame 2 can only move up and down, without any displacement to the left, right, or front and back.

[0132] On the first rod 22, there is a first groove 221 extending along a first direction. The first groove 221 is mainly for accommodating the extension 312 of the constant force spring. The first groove 221 extends along the first direction, which is consistent with the extension direction of the first rod 22 and the movement direction of the second frame 2.

[0133] The coiled portion 311 of the constant force spring is connected to the second frame 2, and the extension portion 312 is connected to the first frame 1. Thus, the extension portion 312 can be placed within the first groove 221. This arrangement serves two purposes: firstly, the first groove 221 provides a safe protective space for the extension portion 312 of the constant force spring. During the movement of the second frame 2, the extension portion 312 is surrounded by the first groove 221, effectively preventing collisions or interference from external objects, thereby reducing the risk of deformation or damage to the extension portion 312. Secondly, since the first groove 221 moves in the same direction as the second frame 2, when the second frame 2 moves in the first direction, the first rod 22 also moves accordingly. At this time, the extension portion 312 of the constant force spring can smoothly stretch or retract within the first groove 221, thus providing a certain limiting effect. Finally, the first groove 221 also serves to conceal the extension portion 312, preventing it from being exposed and making the overall speaker bracket more aesthetically pleasing. Figure 4 and Figure 14 In the illustrated embodiment, the first rod 22 is made of profile material and has a natural groove as the first groove 221. The first groove 221 is located on its side, and the extension 312 is placed inside it, completely concealing it and providing a good hiding effect. Additionally, an end cap 222 can be provided at the end of the first rod 22 to protect the end. Figure 14 and Figure 15 In the embodiment shown, a sliding sleeve 11 is provided on the first frame, and the first rod 22 is inserted into the sliding sleeve 11.

[0134] Please see Figure 16 and Figure 17 In some embodiments of this application, the second frame 2 includes a speaker mounting part 24 and a main body part 23. The speaker mounting part 24 is used to mount a speaker 6. The speaker mounting part 24 can move relative to the main body part 23 in a third direction, and the first direction and the third direction are not parallel.

[0135] In this embodiment, the second frame 2 includes a speaker mounting section 24 and a main body 23. The main function of the speaker mounting section 24 is to provide a mounting position for the speaker 6. It is designed to specifically fit the shape and size of the speaker 6 and may have specific fixing interfaces, screw holes, or clips to securely mount the speaker 6. The main body 23 is the main supporting part of the second frame 2. It is connected to the first frame 1 through the first rod 22 and the first through hole, and provides a foundation for the installation and movement of the speaker mounting section 24.

[0136] The speaker mounting section 24 has the ability to move relative to the main body section 23 in a third direction. This third direction is not parallel to the first and second directions mentioned earlier. The first direction refers to the direction in which the second frame 2 moves relative to the first frame 1, i.e., one adjustment direction for the speaker 6. The third direction is another adjustment direction for the speaker 6. Since the first and third directions are not parallel, the speaker 6 can be adjusted in both directions. For example, in the most common case, the first direction is vertical, and the third direction is the front-to-back direction in the horizontal direction, i.e. Figure 16 The Y direction shown allows the speaker 6 to be adjusted in both vertical and horizontal positions.

[0137] Various adjustment components of different structures can be installed between the speaker mounting section 24 and the main body section 23 to achieve relative adjustment, such as tracks, electric actuators, pneumatic actuators, etc. Figure 16 and Figure 17In the illustrated embodiment, the adjustment assembly is positioned between the speaker mounting section 24 and the main body 23, and its working principle is based on the scissor arm 5 structure. The following explanation uses the installation of a long, narrow speaker 6 as an example to illustrate this structural principle. For speakers 6 of other shapes, the installation method may need to be adjusted accordingly. This assembly is designed with two sets of scissor arms 5, left and right, for mounting the long, narrow speaker 6. This design not only allows adjustment of the front-to-back distance between the speaker 6 and the television 7, but also allows adjustment of the angle between the speaker 6 and the television 7 within a certain range. The assembly mainly includes a main sheet metal body, a first mounting plate 241, scissor arms 5, a large slider 52, a second hinge pin 54, a mounting base 231, a small slider 53, a spacer post 57, and a second mounting plate 242. The main sheet metal body and the mounting base 231 are connected by screws, separated by a spacer pad 56.

[0138] Since the left and right sets of scissor arm 5 have the same structure, the left scissor arm 5 will be used as an example for explanation. The scissor arm 5 is connected to components such as the pad 51 and washer 55 via screws. The rotating ends of the scissor arm 5 are fixed to the first mounting plate 241 and the mounting base 231, respectively, with the first mounting plate 241 and the mounting base 231 connected by a spacer 57 and a large slider 52. One moving end of the scissor arm 5 is mounted in the left mounting plate via the second hinge 54 and the large slider 52, while the other moving end is mounted in the mounting base 231 via the second hinge 54 and the small slider 53.

[0139] When the front-to-back position of the speaker 6 needs to be adjusted, the rotating end of the scissor arm 5 rotates within the left mounting plate and mounting base 231. Simultaneously, under the action of the second hinge pin 54 and the large slider 52, one moving end of the scissor arm 5 moves within the left mounting plate; under the action of the second hinge pin 54 and the small slider 53, the other moving end moves within the mounting base 231. This changes the included angle of the scissor arm 5, causing a change in the distance between the speaker 6 mounting plate and the mounting base 231, thus achieving the adjustment of the front-to-back distance of the speaker 6.

[0140] Based on the speaker stand described above, please refer to Figure 18 and Figure 19 This application also provides a bracket kit, which includes:

[0141] The aforementioned speaker stand;

[0142] Display device bracket; the display device bracket includes a display mounting component for mounting a display device; the first frame 1 of the audio bracket is connected to the display mounting component.

[0143] For those who demand a high level of audiovisual ambiance, the built-in speakers of display devices such as TVs and monitors are often insufficient, necessitating the purchase of dedicated speakers. Currently, most speakers are designed for floor-standing or wall-mounted use. However, these speakers are not ideal for TVs equipped with extendable, height-adjustable, and rotatable multi-functional TV stands. Firstly, adjusting the height, angle, or distance of the TV without moving the speakers negatively impacts the overall ambiance. Secondly, the inconsistency between the viewing position and the speaker placement disrupts the overall audiovisual atmosphere, especially for those with high expectations, requiring adjustments to the speaker position after each TV viewing. Therefore, speakers that can move synchronously with the TV and are suspended from it have emerged. The challenge then becomes how to perfectly integrate these speakers with TVs of different models and sizes.

[0144] This embodiment solves this problem. In this embodiment, the bracket kit includes the speaker bracket and display device bracket from the above embodiments. The main function of the display device bracket is to mount display devices, such as televisions, computer monitors, etc. The display mounting component is a key part of the display device bracket; it is designed to be specifically adapted to various display devices and may have screw holes, slots, or other fixing devices to securely mount the display device.

[0145] The first frame 1 of the speaker bracket is connected to the display mounting component of the display device bracket. This connection method ensures that when the display device bracket is adjusted, such as by adjusting the height or angle of the display device, the speaker bracket will adjust synchronously. Because the first frame 1 of the speaker bracket is connected to the display mounting component, any movement or adjustment of the display mounting component will be transmitted to the first frame 1 of the speaker bracket, thereby causing a corresponding positional change in the entire speaker bracket, thus matching the viewing position with the position of the speakers 6. For example, when the user wants to raise the height of the display device, by operating the display device bracket to move the display mounting component upwards, the first frame 1 of the speaker bracket connected to the display mounting component will also move upwards, thereby raising the entire speaker bracket, and the speakers 6 mounted on the second frame 2 of the speaker bracket will also rise to the corresponding position.

[0146] Furthermore, since the position of the speaker 6 can be adjusted by the relative movement of the first frame 1 and the second frame 2, the speaker 6 can be matched with display devices of different sizes.

[0147] In such Figure 18 and Figure 19In the embodiment shown, the display device bracket is a TV bracket 8. After aligning the lower row of mounting holes of the TV 7 with the corresponding mounting holes on the crossbar of the speaker bracket and the corresponding lower mounting holes of the TV bracket 8, screws are used to tighten them. The upper row of mounting holes of the TV 7 is aligned with the corresponding upper mounting holes of the TV bracket 8. The space in the middle is leveled by a spacer 81 and then tightened with screws, so that the speakers 6 on the speaker bracket can be adjusted synchronously with the TV 7.

[0148] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
