Description

Technical Field

[0001] The utility model relates to the technical field of sound boxes, in particular to a line array assembleable sound box. Background Art

[0002] A speaker is a device that converts audio signals into sound. Generally speaking, it refers to a speaker cabinet or subwoofer housing with a built-in power amplifier that amplifies the audio signal and then plays it back, making it louder. The speaker is the terminal of the entire sound system, converting audio electrical energy into sound energy and radiating it into the air. It is an extremely important component of the sound system, responsible for converting electrical signals into sound signals for direct human hearing. Line array speakers are a group of closely spaced radiating elements arranged in a straight line with the same amplitude and phase, providing better sound quality, better coverage, and more efficient use of amplifier power.

[0003] The various boxes of the current line array speakers are fixed with bolts, which is not only cumbersome but also inconvenient to adjust. Therefore, we propose a modular line array speaker. Utility Model Content

[0027] Example 1

[0028] Reference Figure 1-Figure 5 , a line array assembled speaker, comprising:

[0029] Base plate 1;

[0030] There are three support rods 2, which are fixedly mounted on the top of the bottom plate 1. A mounting block 3 is slidably connected to the support rod 2. A fixing box 4 is rotatably connected to one side of the mounting block 3. A speaker body 7 is placed on one side of the fixing box 4. The top ends of the three support rods 2 are fixedly mounted with the same top plate.

[0031] The clamping mechanism is mounted on the fixing box 4 and cooperates with the speaker body 7;

[0032] The adjusting component is installed on the clamping mechanism.

[0033] In this embodiment, the clamping mechanism includes four symmetrically arranged clamping plates 6, four symmetrically arranged pull rods 5 are slidably connected to the fixed box 4, the clamping plates 6 are slidably installed on the pull rods 5, and the clamping plates 6 cooperate with the audio body 7. A turntable 14 is rotatably connected to the inner wall of one side of the fixed box 4, and four arc-shaped grooves 15 are opened on one side of the turntable 14. A slider 16 is slidably connected to the inner wall of the arc-shaped groove 15, and the slider 16 is fixedly connected to the corresponding pull rod 5. The rotating turntable 14 is slidably connected to the slider 16 through the arc-shaped groove 15, thereby driving the pull rod 5 to move. The pull rod 5 clamps and fixes the audio body 7 through the clamping plates 6, and at the same time, the pull rod 5 is limited by the sliding connection with the fixed box 4.

[0034] In this embodiment, the adjustment assembly includes a rotating block 8, which is rotatably installed on the splint 6, and the pull rod 5 is provided with a thread. The rotating block 8 is threadedly connected to the pull rod 5. The cross-section of the pull rod 5 is a fan-shaped surface. A fan-shaped hole is provided on the rotating block 8, and the fan-shaped hole is slidingly connected to the pull rod 5. The rotating rotating block 8 is connected to the pull rod 5 through a thread, and the splint 6 is slidingly connected to the pull rod 5, so that the position of the splint 6 on the pull rod 5 can be adjusted, and then the clamping size of the splint 6 can be adjusted, so that the audio body 7 of different sizes can be clamped and fixed.

[0035] In this embodiment, a positioning box 9 is fixedly installed on one side of the fixed box 4, and an active rod 10 is rotatably connected in the positioning box 9. A positioning shaft 11 is fixedly installed on one side of the turntable 14. The active rod 10 is transmission-connected to the positioning shaft 11. A worm 12 is fixedly installed on the active rod 10, and a worm wheel 13 is fixedly installed on the positioning shaft 11. The worm 12 and the worm wheel 13 are engaged with each other. The rotating active rod 10 can drive the positioning shaft 11 to rotate through the mutual engagement of the worm 12 and the worm wheel 13, and then drive the turntable 14 to rotate. At the same time, the mutual engagement of the worm 12 and the worm wheel 13 can lock the angle of the positioning shaft 11.

[0036] In this embodiment, the top of the mounting block 3 is rotatably connected to a rotating plate 17, and a thread is provided on the support rod. The rotating rotating plate 17 is threadedly connected to the support rod. The rotating rotating plate 17 rotates with the mounting block 3, and the rotating plate 17 is threadedly connected to the support rod 2, so that the position of the audio body 7 can be adjusted, and then the distance during assembly can be adjusted to adapt to use in different spaces.

[0037] The implementation principle of the line array assembled speaker of the embodiment of the present application is as follows: when working, the speaker body 7 is placed between the four clamping plates 6, and the active rod 10 is rotated. The rotating active rod 10 is engaged with the worm 12 and the worm wheel 13, thereby driving the positioning shaft 11 to rotate, and then driving the turntable 14 to rotate. At the same time, the worm 12 and the worm wheel 13 are engaged with each other, so that the angle of the positioning shaft 11 can be locked. The rotating turntable 14 is connected to the sliding block 16 through the arc groove 15, thereby driving the pull rod 5 to move. The pull rod 5 clamps and fixes the speaker body 7 through the clamping plates 6, and the pull rod 5 is connected with the sliding block 16 through the arc groove 15. Through the sliding connection with the fixed box 4, the pull rod 5 can be limited. When it is necessary to clamp and fix the audio bodies 7 of different sizes, the rotating block 8 is rotated. The rotating block 8 is connected to the pull rod 5 through a thread, and the clamping plate 6 is slidably connected to the pull rod 5, so that the position of the clamping plate 6 on the pull rod 5 can be adjusted, and then the clamping size of the clamping plate 6 can be adjusted, so that the audio bodies 7 of different sizes can be clamped and fixed. The rotating turn plate 17 is rotated with the mounting block 3, and the turn plate 17 is threadedly connected to the support rod 2, so that the position of the audio body 7 can be adjusted, and then the distance during assembly can be adjusted to adapt to use in different spaces.

[0038] Example 2

[0039] The difference between the second embodiment and the first embodiment is that the bottom plate 1 is a hinged assembly of multiple short rods. The hinged assembly of multiple short rods enables multiple audio bodies 7 to face different angles, so that they can be used to produce sound at different angles, resulting in different effects.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
