Description

Technical Field

[0001] This utility model belongs to the technical field of conference sound reinforcement devices, and particularly relates to an equal sound pressure digital conference sound reinforcement device. Background Technology

[0002] In conference sound reinforcement systems, the installation, deployment, and stable operation of loudspeakers directly affect the sound pressure level amplification effect. However, existing conference sound reinforcement devices have many problems that urgently need to be solved in practical use.

[0003] First, the installation process for traditional loudspeakers is complex, relying heavily on bolts, clips, and other fasteners. It requires specialized tools such as screwdrivers and wrenches for step-by-step assembly, making the process cumbersome and demanding professional precision control, resulting in lengthy deployment times. In conference settings, there are often needs to adjust venue layouts or urgently add equipment; traditional installation methods struggle to meet the requirements for rapid deployment, easily delaying conference preparation.

[0004] Secondly, existing devices lack sufficient stability in supporting the loudspeakers. Some devices rely solely on a single connection structure to bear the speaker's weight, resulting in concentrated stress points. Over long-term use, vibrations and the device's own weight can cause the connection to loosen, leading to speaker wobbling. Even worse, if the support structure fails, there is a risk that the speaker may deflect or even detach from the mounting base, affecting not only the sound reinforcement effect but also posing a safety hazard of the device falling.

[0005] Finally, meeting spaces vary in size, requiring adjustments to the spacing of multiple speakers to achieve equal sound pressure coverage. However, traditional devices lack stable positioning mechanisms. After adjusting the spacing, they are fixed only by simple limiting components, which can easily lead to spacing deviation due to external interference, disrupting the equal sound pressure field distribution. This results in significant differences in the auditory experience of participants in different positions, failing to guarantee the consistency of the sound reinforcement effect, and urgently needs improvement. Therefore, we propose an equal sound pressure digital conference sound reinforcement device. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned technical problems by providing an equal sound pressure level digital conference sound reinforcement device, which achieves the effect of quickly installing and adjusting the distance and positioning of loudspeakers.

[0007] In view of this, the present invention provides an equal sound pressure level digital conference sound reinforcement device, including a fixed frame, a speaker at the lower end of the fixed frame, a fixed rod detachably mounted at the upper end of the speaker, a support block mounted at the upper end of the fixed rod, a strip groove in the middle of the upper end of the fixed frame, a horizontal end face on one side of the support block, an I-shaped plate at the upper end of the support block, a mounting assembly disposed above the fixed frame, the horizontal end face of the support block being perpendicular to the direction of the strip groove for mounting and limiting the speaker, and a positioning assembly comprising fixed plates disposed on both sides of the fixed frame, a first toothed plate at the upper end of the fixed plate, and second toothed plates on both sides of the I-shaped plate for positioning the multiple speakers with adjustable spacing.

[0008] Furthermore, the installation assembly includes hangers mounted on a fixed frame, the hangers being symmetrically arranged and fixedly connected to the fixed frame by bolts, and a support block being mounted on the upper end of the strip groove, with the lower end of the support block abutting against the upper end of the fixed frame.

[0009] Furthermore, the fixing plate is fixedly connected to the first toothed plate by welding, and the second toothed plate is welded to both sides of the I-shaped plate, with the two second toothed plates arranged symmetrically.

[0010] Furthermore, the upper ends of the I-shaped plate are provided with support ends on both sides, the upper end of the first toothed plate is aligned with the support ends, and the upper edge of the first toothed plate is in contact with the lower end of the support end.

[0011] Furthermore, a positioning rod is welded to the inner side of one end of the fixing plate, and a sleeve is provided on the side of the fixing frame near the positioning rod, and the sleeve is movably connected to the positioning rod.

[0012] Furthermore, a lead screw sleeve is fixedly installed at the other end of the fixing plate, and a bidirectional lead screw is provided on the side of the fixing frame near the lead screw sleeve. The size of the bidirectional lead screw is adapted to the size of the lead screw sleeve, and the bidirectional lead screw is threadedly connected to the lead screw sleeve.

[0013] Furthermore, the length of the first toothed plate is the same as the length of the strip groove, and the two first toothed plates are arranged symmetrically.

[0014] Furthermore, the first toothed plate corresponds to the second toothed plate, and the first toothed plate meshes with the second toothed plate.

[0015] Furthermore, the width of the I-shaped plate is smaller than the diameter of the support block.

[0016] The beneficial effects of this utility model are: By using the horizontal end face of the support block to engage with the strip groove, the speaker installation process is greatly simplified, allowing for quick assembly without complex tools and significantly improving installation efficiency. This makes it suitable for rapid deployment and adjustment of equipment in conference settings. Secondly, the contact support between the edge of the support block and the mounting bracket provides a stable foundation for the speaker, preventing equipment shaking due to unstable support during initial installation. Thirdly, the interlocking structure of the first toothed plate and the I-shaped plate in the positioning assembly not only provides secondary support to the support block, further enhancing the overall support strength, but also effectively restricts speaker rotation, avoiding the risk of the support block detaching from the mounting bracket due to speaker deflection. This ensures long-term stable operation of the equipment during conference use and ensures that the equal sound pressure level amplification effect is not affected by equipment displacement. Finally, after the speaker spacing is adjusted, the first and second toothed plates mesh with each other to position multiple speakers with adjustable spacing. Attached Figure Description

[0023] Reference Figures 1 to 4 A digital conference sound reinforcement device with equal sound pressure level includes a mounting frame 1, a speaker 13 at the lower end of the mounting frame 1, a fixing rod 14 detachably mounted at the upper end of the speaker 13, a support block 15 mounted at the upper end of the fixing rod 14, a strip groove 12 in the middle of the upper end of the mounting frame 1, a horizontal end face 16 on one side of the support block 15, an I-shaped plate 22 at the upper end of the support block 15, a mounting assembly, located above the mounting frame 1, perpendicular to the direction of the horizontal end face 16 of the support block 15 and the strip groove 12, used to limit the installation of the speaker 13, and a positioning assembly, including fixing plates 2 on both sides of the mounting frame 1, a first toothed plate 21 at the upper end of the fixing plate 2, and second toothed plates 24 on both sides of the I-shaped plate 22, used to position multiple speakers 13 with adjustable spacing.

[0024] During installation, the mounting bracket 1 is first installed in a suitable location in the conference room using the hanger 11. Then, the support block 15 is inserted into the slot 12. The support block 15 (its width is less than the width of the slot 12, but its length is greater than the width of the slot 12) is rotated so that its horizontal end face 16 is perpendicular to the slot 12. This allows the speaker 13 assembly to be quickly snapped into the slot 12, completing the initial assembly without complex fasteners and enabling rapid installation and deployment in conference settings. Furthermore, the contact between the edge of the support block 15 and the upper surface of the mounting bracket 1 forms the first layer of support for the speaker 13. The force transmission characteristics of surface contact distribute the weight of the speaker 13. This allows for the placement of multiple speakers 13. After the distance is adjusted to the correct position, the positioning component is activated. The first toothed plate 21 is inserted into the structural gap of the I-shaped plate 22 along a preset trajectory. On the one hand, the mechanical engagement between the first toothed plate 21 and the I-shaped plate 22 forms a second layer of support, further enhancing the structural load-bearing capacity and distributing the weight of the speaker 13 again, ensuring the stability of the speaker 13 installation. On the other hand, the toothed plate and the I-shaped plate 22 cooperate to restrict the rotation of the support block 15, preventing the support block 15 from deflecting and disengaging from the strip groove 12 due to vibration or collision. At the same time, the first toothed plate 21 and the second toothed plates 24 on both sides of the I-shaped plate 22 form a meshing lock, and the synchronous positioning of multiple speakers 13 is achieved through the mechanical limiting between the teeth, providing a structural basis for equal sound pressure level sound reinforcement.

[0025] In the example of this application, the installation component includes a hanger 11 disposed on the fixed frame 1. The hangers 11 are symmetrically arranged and are fixedly connected to the fixed frame 1 by bolts. The support block 15 is disposed at the upper end of the strip groove 12, and the lower end of the support block 15 is in contact with the upper end of the fixed frame 1.

[0026] As a preferred example of this utility model, the total weight of the mounting bracket 1 and the speaker 13 is evenly transferred to the mounting base (such as the ceiling or bracket) by symmetrically arranged hangers 11, which avoids bending and deformation of the mounting bracket 1 caused by unilateral force and ensures the long-term stability of the overall structure.

[0027] In the example of this application, the fixing plate 2 is fixedly connected to the first toothed plate 21 by welding, and the second toothed plate 24 is welded to both sides of the I-shaped plate 22, and the two second toothed plates 24 are symmetrically arranged.

[0028] As a preferred example of this utility model, the fixing plate 2 and the first toothed plate 21, and the second toothed plate 24 and the I-shaped plate 22 are all welded together, thus forming an integrated rigid structure and avoiding positioning errors caused by loose connections. The symmetrical arrangement of the second toothed plate 24 creates symmetrical force points on both sides of the I-shaped plate 22. When the first toothed plate 21 and the second toothed plate 24 mesh, the tooth surfaces on both sides bear the force simultaneously, ensuring full contact of the meshing surfaces. This, in turn, ensures the accuracy of the speaker spacing adjustment and guarantees the achievement of equal sound pressure level amplification.

[0029] In the example of this application, support ends 23 are provided on both sides of the upper end of the I-shaped plate 22, the upper end of the first toothed plate 21 is aligned with the support ends 23, and the upper edge of the first toothed plate 21 is in contact with the lower end of the support ends 23.

[0030] As a preferred example of this utility model, when the first toothed plate 21 and the second toothed plate 24 are engaged, the support end 23 forms a surface contact with the upper surface of the first toothed plate 21, transferring part of the vertical load borne by the I-shaped plate 22 to the first toothed plate 21, thereby distributing the weight of the speaker 13, avoiding the weight being concentrated on the support block 15, and thus ensuring the stable operation of the speaker 13 in the set position, and ensuring the coverage effect of the sound reinforcement range.

[0031] In the example of this application, a positioning rod 26 is welded to the inner side of one end of the fixing plate 2, and a sleeve 25 is provided on the side of the fixing frame 1 near the positioning rod 26. The sleeve 25 is movably connected to the positioning rod 26.

[0032] As a preferred example of this utility model, the movement trajectory of the positioning rod 26 is constrained by the inner wall of the sleeve 25, so that when the fixing plate 2 drives the first toothed plate 21 to move, it always moves in a direction perpendicular to the strip groove 12, avoiding the misalignment between the first toothed plate 21 and the second toothed plate 24 caused by lateral displacement.

[0033] In the example of this application, a lead screw sleeve 4 is fixedly installed at the other end of the fixing plate 2, and a bidirectional lead screw 3 is provided on the side of the fixing bracket 1 near the lead screw sleeve 4. The size of the bidirectional lead screw 3 is adapted to the size of the lead screw sleeve 4, and the bidirectional lead screw 3 is threadedly connected to the lead screw sleeve 4.

[0034] As a preferred example of this utility model, when the bidirectional lead screw 3 rotates under the action of external driving force, its left and right threads drive the lead screw sleeves 4 on both sides to move synchronously in opposite directions. Through the connection between the lead screw sleeves 4 and the fixed plate 2, the first toothed plates 21 on both sides can be driven to move synchronously in opposite directions, thereby achieving the position limitation of the adjusted speaker 13.

[0035] In the example of this application, the length of the first toothed plate 21 is the same as the length of the strip groove 12, and the two first toothed plates 21 are symmetrically arranged.

[0036] As a preferred example of this utility model, by extending the effective engagement length, the installation and adjustment range of the speaker 13 is expanded, thereby improving the adaptability of the device to different conference room spaces. Furthermore, the symmetrical arrangement of the two first toothed plates 21 ensures that both sides of the speaker 13 are simultaneously subjected to the engagement force of the toothed plates, ensuring that the axis of the speaker 13 always remains vertical, thus guaranteeing the stability of the speaker 13's positioning.

[0037] In the example of this application, the first toothed plate 21 corresponds to the second toothed plate 24, and the first toothed plate 21 meshes with the second toothed plate 24.

[0038] As a preferred example of this utility model, the first toothed plate 21 and the second toothed plate 24 adopt a complementary tooth profile design. When meshing, the tooth peaks and tooth valleys form a tight fit. The constraint force of the tooth surface restricts the relative sliding of the two toothed plates, thereby fixing the relative position of the I-shaped plate 22 and the fixed plate 2, realizing the spacing lock of the speaker 13. This ensures that multiple speakers 13 achieve equal sound pressure effect in the conference space through sound wave superposition and coverage optimization, ensuring the consistency of the auditory experience of participants in different positions.

[0039] In the example of this application, the width of the I-shaped plate 22 is smaller than the diameter of the support block 15.

[0040] As a preferred example of this utility model, the smaller width of the I-shaped plate 22 provides sufficient space for the first toothed plate 21 to be inserted, reducing the structural interference between the first toothed plate 21 and the support block 15, ensuring that the first toothed plate 21 can be smoothly inserted into the gap between the two sides of the I-shaped plate 22 and the support block 15, achieving precise engagement with the second toothed plate 24, thereby ensuring the smooth implementation of the positioning component function.

[0041] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
