Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to a vertical loudspeaker mounting bracket and loudspeaker system. Background Technology

[0002] Point source loudspeakers play a crucial role in audio systems. Their enclosures are often designed as symmetrical equilateral trapezoids with angles typically between 18° and 24° or greater. This design helps reduce sound wave reflections and standing wave phenomena in front of and behind the loudspeaker, improving sound quality. However, traditional vertical mounting brackets for these loudspeakers usually require additional adapters to accommodate the specific angle of the enclosure. Since the enclosure angle is not fixed, each enclosure angle requires a custom-made adapter. Furthermore, the speaker angle is fixed using angle adjustment screws, which necessitates frequent tightening and loosening of these screws when adjusting the enclosure's tilt angle. This significantly increases the complexity and time cost of installation and setup. Utility Model Content

[0034] Figure 1 and Figure 2 A loudspeaker system according to some embodiments of the present application is shown, for example, Figure 1 and Figure 2As shown, the loudspeaker system comprises a loudspeaker 20 and a loudspeaker vertical mounting bracket 10 for mounting the loudspeaker 20. The loudspeaker 20 can be a point sound source loudspeaker, and the cabinet 201 of the point sound source loudspeaker is generally in the shape of a symmetrical isosceles trapezoid with an angle generally between 18°-24° or more. The loudspeaker vertical mounting bracket 10 can be adapted to loudspeaker cabinets 201 with different angles of inclination, and can be used to adjust the angle of inclination of the loudspeaker 20.

[0035] As shown in Figure 3 and Figure 4 , the loudspeaker vertical mounting bracket 10 comprises a bracket body 1 and an angle adapting assembly 2. The bracket body 1 comprises support arms 11 provided on the side portions, which are used to mount the angle adapting assembly 2 to mount and support the loudspeaker 20.

[0036] The angle adapting assembly 2 is provided on the inner side of the support arms 11. Preferably, the support arms 11 can be provided with at least two, which are used to support the cabinet 201 of the loudspeaker 20 on at least two sides. The angle adapting assembly 2 is provided corresponding to the support arms 11 and on the inner side of the support arms 11.

[0037] The angle adapting assembly 2 comprises a first connecting piece 21 connected with the support arms 11 and a second connecting piece 22 used to connect with the loudspeaker 20. The first connecting piece 21 can rotate relative to the support arms 11 about a first axis A intersecting the support arms 11 and the first connecting piece 21. Understandably, the angle adapting assembly 2 is connected with the support arms 11 through the first connecting piece 21, which can rotate relative to the support arms 11 to adjust the angle of inclination of the angle adapting assembly 2, thereby adjusting the angle of inclination of the loudspeaker 20.

[0038] The first connecting piece 21 and the support arms 11 can be connected and locked by a locking structure 3. The locking structure 3 comprises a connecting rod 31 penetrating through the support arms 11 and the first connecting piece 21. The first axis A is the axis of the connecting rod 31.

[0039] As shown in Figure 3 and Figure 4 , the locking structure 3 can be a combination screw, the connecting rod 31 is a screw rod, and the first connecting piece 21 and the support arms 11 are provided with first and second hole positions 2111 and 111 for the connecting rod 31 to penetrate. The locking structure 3 further comprises a pre-tightening elastic washer 32 and a flat washer 33 provided between the screw head of the connecting rod 31 and the support arms 11, and a nut 34 fitted and locked on the side of the first connecting piece 21 away from the support arms 11. The pre-tightening elastic washer 32 and the flat washer 33 serve the function of preventing loosening.

[0040] Preferably, the nut 34 is fixed to the side of the first connecting piece 21 away from the support arm 11, for example, the nut 34 is welded with the first connecting piece 21 as a whole, so that the nut 34 does not need to be repeatedly adjusted when adjusting the inclination angle of the loudspeaker 20.

[0041] The first connecting piece 21 and the support arm 11 can be arranged in parallel, the connecting rod 31 is perpendicular to the first connecting piece 21 and the support arm 11, and the first connecting piece 21 can rotate 360° around the connecting rod 31 relative to the support arm 11, so as to facilitate adjusting the loudspeaker 20 to different inclination angles.

[0042] As shown in Figure 3 and Figure 4 , the loudspeaker vertical mounting bracket 10 further comprises an inclination adjusting structure 4, which is used for adjusting the first connecting piece 21 to different inclination angles and fixing the first connecting piece 21 at the inclination angle position. The inclination adjusting structure 4 comprises at least two insertion holes 41 arranged on the first connecting piece 21, and a latch structure 42 arranged on the support arm 11. The at least two insertion holes 41 are arranged in the circumferential direction of the first axis A, i.e. the at least two insertion holes 41 are arranged in the circumferential direction of the first hole position 2111. The latch structure 42 can move towards the first connecting piece 21 and be inserted into the insertion hole 41, and can move away from the first connecting piece 21 to be detached from the insertion hole 41.

[0043] It can be understood that the at least two insertion holes 41 are arranged in the circumferential direction of the first axis A, so that when the first connecting piece 21 rotates, the latch structure 42 can correspond to different insertion holes 41. In this way, the latch structure 42 is inserted into different insertion holes 41, so that the first connecting piece 21 is kept at different inclination angles.

[0044] The latch structure 42 can be a spring latch structure, as shown in Figure 5 and Figure 6 , the latch structure 42 comprises a fixed seat 421 fixed to the support arm 11, a receiving cavity 422 arranged in the fixed seat 421 and penetrating the fixed seat 421 close to the end of the first connecting piece 21, an insertion part 423 arranged in the receiving cavity 422 and at least partially extending out of the receiving cavity 422, an elastic member 424 providing an elastic force to the insertion part 423 towards the side of the first connecting piece 21, and an operation part 425 arranged outside the fixed seat 421 and connected with the insertion part 423.

[0045] It can be understood that the fixing seat 421 can be arranged on the side of the support arm 11 away from the first connecting piece 21, and the support arm 11 is provided with a through hole 112 for the insertion part 423 to pass through. When the inclination angle of the loudspeaker 20 needs to be adjusted, the operation part 425 is moved to drive the insertion part 423 to move towards the side away from the first connecting piece 21, so that the insertion part 423 is pulled out of the insertion hole 41, and then the first connecting piece 21 is rotated to the desired inclination angle position, and then the operation part 425 is released. The insertion part 423 is inserted into the corresponding insertion hole 41 under the elastic force of the elastic member 424, so as to realize the inclination angle adjustment.

[0046] The elastic member 424 is arranged to automatically lock the insertion part 423 in the new position after the adjustment is completed, thereby ensuring the stability and reliability of the adjustment. The fixing seat 421 can be integrally welded with the support arm 11.

[0047] Further, the insertion part 423 can include an embedded segment 4231 and an insertion segment 4232 arranged in the axial direction, the insertion segment 4232 is closer to the first connecting piece 21 than the embedded segment 4231, and the radial dimension of at least part of the insertion segment 4232 is greater than the radial dimension of the embedded segment 4231; the fixing seat 421 is provided with an opening 4211 at the end away from the first connecting piece 21 for the embedded segment 4231 to extend out and limit the insertion segment 4232 to extend out; the operation part 425 is connected to the end of the embedded segment 4231 away from the insertion segment 4232; and the elastic member 424 is sleeved on the outer periphery of the embedded segment 4231 and abuts against the insertion segment 4232. The elastic member 424 can be a spring.

[0048] The operation part 425 can be a pull ring connected to the end of the embedded segment 4231 away from the insertion segment 4232 and located outside the fixing seat 421, and the embedded segment 4231 is provided with a hole position for the pull ring to pass through. The size of the opening 4211 can be slightly larger than the size of the embedded segment 4231 and smaller than the size of the insertion segment 4232, so as to allow the embedded segment 4231 to extend out and limit the insertion segment 4232 to extend out, and the size of the operation part 425 is greater than the size of the opening 4211, so as to be exposed outside the fixing seat 421 for the user to grasp.

[0049] Therefore, when the pull ring is pulled towards the side away from the first connecting piece 21, the pull ring drives the embedded segment 4231 to extend outwards through the hole position, and the insertion segment 4232 extends into the accommodating cavity 422 and is pulled out of the insertion hole 41.

[0050] The inclination adjustment structure 4 is arranged to allow the user to quickly adjust the inclination angle of the loudspeaker 20 by simply pulling the operation part 425 and rotating the first connecting piece 21, thereby improving the flexibility and convenience of installation.

[0051] In some embodiments, the pin structure 42 may also be implemented using a single pin with a locking mechanism, which is characterized by low cost and ease of implementation.

[0052] like Figure 4 As shown, at least two sockets 41 on the first connector 21 include a plurality of sockets 41, which form a circular array. Understandably, there are multiple sockets 41 to allow for various tilt angle adjustments.

[0053] Optionally, adjacent sockets 41 may differ by less than 18° in the circumferential direction. For example, each socket 41 may be arranged in a manner that differs by 1°-18° in the circumferential direction. These sockets 41 may be evenly spaced or non-uniformly spaced.

[0054] Preferably, such as Figure 4 As shown, the plurality of sockets 41 are symmetrically arranged relative to the axis C of the first connector 21. It can be understood that in the embodiment where the angle adapter 2 is arranged on both sides, if the sockets 41 on the first connector 21 are symmetrical relative to the axis C of the first connector 21, the same angle adapter 2 can be applied to both sides without distinguishing between production and installation.

[0055] A support arm 11 extends radially along the first axis A and blocks at least two insertion holes 41; and / or, a damping plate 5 is provided between the support arm 11 and the first connector 21. Understandably, in some embodiments, the support arm 11 extends radially along the first axis A and blocks at least two insertion holes 41. In some embodiments, a damping plate 5 is provided between the support arm 11 and the first connector 21. In some embodiments, the support arm 11 extends radially along the first axis A and blocks at least two insertion holes 41; and a damping plate 5 is provided between the support arm 11 and the first connector 21.

[0056] Understandably, the support arm 11 is located outside the first connector 21. The support arm 11 extends radially along the first axis A and completely blocks the socket 41 on its outer side. That is, the distance by which the support arm 11 extends radially along the first axis A is at least equal to the distance between the socket 41 and the first axis A. Understandably, when adjusting the tilt angle of the speaker 20, the support arm 11 can still completely block the socket 41, so that the socket 41 is not exposed, thus serving an aesthetic purpose.

[0057] like Figure 3 and Figure 4As shown, the damping sheet 5 is arranged between the support arm 11 and the first connecting piece 21 and is penetrated by the connecting rod 31. The damping sheet 5 is arranged in a staggered manner with the insertion hole 41, that is, the damping sheet 5 is located inside the circle formed by the insertion hole 41 and does not block the insertion hole 41, so as to avoid affecting the adjustment of the tilt angle of the loudspeaker 20. The thickness of the damping sheet 5 is preferably greater than 2 mm, and the damping sheet 5 can be made of nylon material, rubber material, silica gel material or PP material. The greater the surface roughness of the damping sheet 5, the better the damping effect.

[0058] As shown in Figures 2 to 4 , the angle adapting assembly 2 is connected with the loudspeaker 20 through the second connecting piece 22, the second connecting piece 22 is arranged on the side of the first connecting piece 21 away from the support arm 11 and can rotate relative to the first connecting piece 21 around the second axis B and change the included angle between the plane where the second connecting piece 22 is located and the plane where the first connecting piece 21 is located during the rotation; the second axis B is at an angle with the first axis A.

[0059] As can be understood, when the second connecting piece 22 rotates relative to the first connecting piece 21, the included angle between the plane where the second connecting piece 22 is located and the plane where the first connecting piece 21 is located will change, so that the second connecting piece 22 can be in different tilt angle states, so as to be fitted to loudspeakers 20 with different tilt angles, thereby realizing stable installation.

[0060] The second connecting piece 22 can be hingedly connected with the first connecting piece 21, wherein the angle adapting assembly 2 further comprises a rotating shaft 23, the first connecting piece 21 and the second connecting piece 22 are respectively provided with shaft tubes 24 on the side portions and are respectively sleeved on the rotating shaft 23 through the shaft tubes 24; wherein the second axis B is the axis of the rotating shaft 23, and the axis of the rotating shaft 23 is perpendicular to the axis of the connecting rod 31.

[0061] As can be understood, the angle adapting assembly 2 has a loose-leaf structure, and the shaft tube 24 on the first connecting piece 21 and the shaft tube 24 on the second connecting piece 22 can be alternately sleeved on the rotating shaft 23, wherein the shaft tube 24 on the first connecting piece 21 can be arranged at intervals along the axial direction of the first connecting piece 21, and the shaft tube 24 on the second connecting piece 22 can be arranged at intervals along the axial direction of the second connecting piece 22.

[0062] Further, as shown in Figure 3 and Figure 4 , the first connecting piece 21 can include a first connecting portion 211 connected with the support arm 11 and a second connecting portion 212 extending from one side of the first connecting portion 211 away from the support arm 11, the first connecting portion 211 is parallel to the support arm 11, the first hole 2111 and the insertion hole 41 are arranged on the first connecting portion 211, and the axis C is the axis of the first connecting portion 211; the shaft tube 24 is arranged on the side of the second connecting portion 212 away from the first connecting portion 211.

[0063] The second connecting part 212 is arranged at an angle with the first connecting part 211, for example, the first connecting part 21 is arranged in an L shape as a whole, so as to form a containing space between the first connecting part 21 and the second connecting part 22, facilitating the arrangement of the locking structure 3.

[0064] The second connecting part 212 is arranged at an angle with the first connecting part 211, for example, the first connecting part 21 is arranged in an L shape as a whole, so as to form a containing space between the first connecting part 21 and the second connecting part 22, facilitating the arrangement of the locking structure 3.

[0065] As shown in the figure, the support body 1 can further include a bottom 12, and the support arms 11 are arranged on both sides of the bottom 12, and the support body 1 is arranged in a U shape as a whole, and has good stability. Figure 3

[0066] Of course, in other embodiments, the support arm 11 can also be provided in three or more quantities, and the angle adapting assembly 2 is correspondingly arranged on each support arm 11, so as to enhance the installation stability of the loudspeaker 20.

[0067] As shown in the figure, in the loudspeaker system, the loudspeaker 20 is installed on the loudspeaker vertical mounting bracket 10 and connected with the second connecting part 22. Figure 2 Specifically, the loudspeaker 20 is installed between the angle adapting assemblies 2, and after the second connecting part 22 of the angle adapting assembly 2 is turned to fit the box body 201 of the loudspeaker 20, the second connecting part 22 and the box body 201 of the loudspeaker 20 are connected and locked through the locking structure.

[0068] The loudspeaker vertical mounting bracket 10 of the utility model can flexibly adapt to the isosceles trapezoidal loudspeaker 20 box body 201 with different inclination angles, without the need to customize multiple angle adapting assemblies 2, improving the universality and reducing the cost, and the inclination angle of the loudspeaker 20 can be adjusted through simple operation, greatly improving the efficiency and convenience of installation and debugging, and the stability and reliability are also guaranteed.
