Description

Technical Field

[0001] This utility model relates to the field of stage acoustic equipment, specifically a detachable stage acoustic reflector. Background Technology

[0002] Stage acoustic reflectors are devices specifically designed to optimize sound propagation in performance venues. Their purpose is to improve the clarity, balance, and naturalness of sound, especially for live music performances that do not use electronic amplification systems.

[0003] Acoustic reflectors work by reflecting and diffusing sound to ensure a more even distribution of sound energy throughout the audience seating area. This is achieved in the following ways:

[0004] Reflection: Reflecting sound upwards and around the stage to ensure that the sound reaches every corner, not just the direct audience.

[0005] Diffusion: To avoid sound focusing and creating hotspots or dead spots, diffusion of sound eliminates echoes and resonance, improving sound clarity.

[0006] A reflector typically consists of several parts, including a top panel, side panels, and a back panel, forming a semi-enclosed space. These panels are usually made of engineered aluminum honeycomb panels, which have good acoustic reflection properties and are lightweight enough to facilitate installation and adjustment.

[0007] However, existing stage acoustic reflectors are not easy to disassemble and install, making them inconvenient to use. Utility Model Content

[0008] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide an acoustic reflector device that can be easily adjusted, installed and disassembled.

[0009] To solve the above problems, the technical solution of this utility model is as follows: a detachable stage acoustic reflector, including a reflector body, the bottom of which is provided with a threaded groove, a connecting cylinder is threadedly connected in the threaded groove, a fixing plate is sleeved on the connecting cylinder, a sliding groove is provided at the bottom of the fixing plate, connecting cylinders are fixedly connected to both sides of the sliding groove, springs are fixedly connected in the connecting cylinder, and a locking block is fixedly connected to the ends of the two springs. The locking block is slidably connected to the sliding groove, and its shape is the same as the cross-section of the sliding groove.

[0010] Furthermore, the reflector body has a conical structure.

[0011] Furthermore, the groove has a T-shaped cross-section.

[0012] Furthermore, the card block has a U-shaped structure, with the length of one side wall being greater than the length of the other side wall.

[0013] Furthermore, the length of the card block is adapted to the depth of the groove.

[0014] Furthermore, a protective cover plate can be snapped onto the fixing plate to protect the spring.

[0015] Furthermore, the reflector body is composed of honeycomb panels.

[0016] The advantages of this invention compared to existing technologies are as follows:

[0017] This utility model has a fixing plate on the rear side of the reflector body. The spring in the groove of the fixing plate can be used to clamp and fix the reflector body by the end of the clamp. When clamping and fixing, the U-shaped structure of the clamp can be used to fix it. During this process, a connecting tube is sleeved on the outside of the spring to restrict the direction, which makes it more convenient to use. Attached Figure Description

[0018] Figure 1 This utility model is a three-dimensional detachable stage acoustic reflector. Figure 1 .

[0019] Figure 2 This is a perspective view of the detachable acoustic reflector for stage use according to this utility model.

[0020] As shown in the figure: 1. Reflector body; 2. Fixing plate; 3. Slide groove; 4. Connecting cylinder; 5. Spring; 6. Locking block. Detailed Implementation

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0022] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0023] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figures 1 to 2As shown, a detachable stage acoustic reflector includes a reflector body 1, which has a conical structure and is composed of honeycomb panels. The bottom of the reflector body 1 has a threaded groove, and a connecting cylinder is threadedly connected within the groove. A fixing plate 2 is fitted onto the connecting cylinder. The bottom of the fixing plate 2 has a sliding groove 3 with a T-shaped cross-section. Connecting cylinders 4 are fixedly connected to both sides of the sliding groove 3. Springs 5 ​​are fixedly connected inside the connecting cylinders 4. Locking blocks 6 are fixedly connected to the ends of the two springs 5. The locking blocks 6 have a U-shaped structure, with one side wall longer than the other. The locking blocks 6 are slidably connected to the sliding groove 3, and their shape is the same as the cross-section of the sliding groove 3. The length of the locking blocks 6 is adapted to the depth of the sliding groove 3. A protective cover plate can be fitted onto the fixing plate 2 to protect the springs 5.

[0025] In practical use, a fixing plate 2 is set on the rear side of the reflector body 1. The spring 5 in the sliding groove 3 on the fixing plate 2 can clamp and fix the reflector body 1 by means of the clamping block 6 at its end. When clamping and fixing, the U-shaped structure of the clamping block 6 can achieve fixation. During this process, a connecting cylinder 4 is sleeved on the outside of the spring 5 to restrict the direction, which makes it more convenient to use.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
