Technical Field

[0001] This utility model relates to the field of line array speaker technology, specifically to a new type of arranged and combined line array speaker. Background Technology

[0002] Line array speakers are a type of sound reinforcement system consisting of multiple closely spaced loudspeaker units with the same amplitude and phase. Through linear arrangement, they form a vertical narrow beam directivity, enabling concentrated sound energy and long-distance transmission.

[0003] Chinese patent document CN221900989U discloses a new type of arranged and combined line array speaker and line array speaker assembly, including a speaker shell, with symmetrically arranged support plates fixedly connected to the front and rear sides of the bottom of the speaker shell, and symmetrically arranged vertical combination plates fixedly connected to the left and right sides of the bottom of the speaker shell, with a slot provided on one side of each of the two vertical combination plates.

[0004] In the above scheme, in order to realize the horizontal and vertical array combination of line array speakers, corresponding combination plates and assembly plates are set at the top and bottom, left and right ends of the speaker shell. However, the speaker has an inherent drawback: each connection dimension (horizontal or vertical) between adjacent speakers needs to be realized through an independent physical interface and locking mechanism, so that fixing any two adjacent speakers requires operating one or more locking points, resulting in redundancy and complexity of the overall structure.

[0015] Example 1; as Figure 1 As shown, this utility model proposes a novel arranged combined line array speaker, including a speaker housing 1, connecting blocks 6, and a second bolt assembly 10. Multiple connecting blocks 6 are installed at the corners of the speaker housing 1. The surface of each connecting block 6 has mounting holes 9 for connecting two adjacent speaker housings 1 together during use. The second bolt assembly 10 is installed inside the mounting holes 9. When multiple speaker housings 1 are placed side-by-side or stacked, the second bolt assembly 10 is inserted into the mounting holes 9, thus fixing the connecting blocks 6 of every two speaker housings 1 together, thereby fixing the multiple speaker housings 1 together into a single unit.

[0016] In an optional embodiment, there are two mounting holes 9, which are arranged at equal angles around the center of the connecting block 6. When two adjacent speaker housings 1 are placed side by side or stacked, the mounting holes 9 on the surface of the connecting block 6 on the two adjacent speaker housings 1 overlap, so that the second bolt assembly 10 is inserted into the mounting holes 9 of the two connecting blocks 6, so that the second bolt assembly 10 connects the two adjacent speaker housings 1 and connects the two adjacent speaker housings 1 into a whole.

[0017] In an optional embodiment, the connecting block 6 is shaped like a cube or three-quarters of a cylinder. During use, two mounting holes 9 are formed at a 90-degree angle on the surface of the connecting block 6. This allows the connecting blocks 6 on two speaker housings 1 to fit together when multiple speaker housings 1 are placed side-by-side or stacked. The mounting holes 9 on the two fitting connecting blocks 6 are also coaxially positioned, allowing the second bolt assembly 10 to be inserted into the mounting holes 9 to fix the two connecting blocks 6. This, in turn, fixes the two speaker housings 1 together, integrating the side-by-side and stacked placement structures of the two speaker housings 1 into one unit, reducing structural complexity and improving the convenience of array placement of the speaker housings 1.

[0018] In an optional embodiment, a protrusion 7 is provided on the side of the connecting block 6. The surface of the protrusion 7 is provided with a mounting groove 8 that is arranged to cooperate with the nut of the second bolt assembly 10. The mounting groove 8 is arranged one-to-one with the mounting hole 9. In use, the thickness of the connecting block 6 is increased by the protrusion 7, and the mounting groove 8 on the surface of the protrusion 7 can place the nut of the second bolt assembly 10 and limit the rotation of the nut. At the same time, the bolt of the second bolt assembly 10 in the mounting hole 9 on the side of the connecting block 6 is connected to the nut inside the mounting groove 8, so that the two connecting blocks 6 can be fixed, improving the convenience of installing the speaker housing 1.

[0019] In this embodiment, by installing the connecting block 6 at the corner of the speaker housing 1, it can control the spacing between two adjacent speaker housings 1 when they are side by side or stacked, and also provide support for the speaker housing 1. When multiple speaker housings 1 need to be arranged side by side or stacked, the connecting blocks 6 of two adjacent speaker housings 1 are stacked and placed together, and the mounting holes 9 on their surfaces are aligned coaxially. Then, the second bolt assembly 10 is placed in the mounting holes 9 of the two connecting blocks 6 and tightened, thereby realizing the tight connection of the two connecting blocks 6. The two adjacent speaker housings 1 are connected as one unit through the cooperation of the connecting block 6 and the second bolt assembly 10. Since the connecting block 6 is a cube or three-quarters of a cylinder, and the two mounting holes 9 on it are arranged at a 90-degree angle, the two speaker housings 1, whether side by side or stacked, can be fixed by the same set of connecting blocks 6, mounting holes 9 and second bolt assembly 10, which greatly simplifies the connection structure and improves the ease of assembly.

[0020] Example 2; as Figure 2-4 As shown, this utility model proposes a new type of arranged combination line array speaker. Compared with the first embodiment, the difference is that the speaker housing 1 is provided with a covering plate 2 at each corner. The connecting block 6 is installed on the covering plate 2. A connecting plate 3 is provided at one end of the covering plate 2, and a mounting plate 5 is provided at the other end of the covering plate 2. The mounting plate 5 and the connecting plate 3 of two adjacent covering plates 2 are slidably connected to each other. The end of the connecting plate 3 is provided with a first bolt assembly 4 connected to the mounting plate 5.

[0021] In an optional embodiment, the mounting plate 5 has a waist-shaped hole in the middle, the size of which matches the first bolt assembly 4, and the length of which matches the length of the connecting plate 3. In use, the first bolt assembly 4 is moved inside the waist-shaped hole of the mounting plate 5 through the connecting plate 3, so that the connecting plate 3 is fitted and connected to the corner of the speaker housing 1. The mounting plate 5 and the connecting plate 3 are fixedly connected through the first bolt assembly 4, so that the covering plate 2 is installed on speaker housings 1 of different sizes.

[0022] In this embodiment, by placing the covering plate 2 at the corner of the speaker housing 1 and placing the first bolt assembly 4 inside the waist-shaped hole of the mounting plate 5, the covering plate 2 is attached to the speaker housing 1 by external force, and the position of the first bolt assembly 4 is adjusted inside the waist-shaped hole of the mounting plate 5. At the same time, the first bolt assembly 4 connects the mounting plate 5 and the connecting plate 3 into a whole, fixing the covering plate 2 to the speaker housing 1, and making the connecting block 6 detachably installed on the speaker housing 1, and placing the connecting block 6 on speaker housings 1 of different rectangular sizes.

[0023] Example 3; as Figure 5As shown, this utility model proposes a novel arranged combined line array speaker. Compared with Embodiment 2, the difference in this embodiment is that both ends of the covering plate 2 are provided with fixing plates 11, and the ends of two adjacent fixing plates 11 are provided with third bolt assemblies 12. The number of third bolt assemblies 12 is at least one, and the ends of the fixing plates 11 have ribs. When the third bolt assemblies 12 adjust the spacing between the two fixing plates 11 so that the covering plate 2 is attached to the speaker housing 1, the covering plate 2 exerts pressure on the speaker housing 1, thereby improving the installation tightness of the covering plate 2 and preventing the ends of the fixing plates 11 from bending due to the tension of the third bolt assemblies 12.

[0024] In this embodiment, the third bolt assembly 12 is connected to two adjacent fixing plates 11, so that the third bolt assembly 12 adjusts the distance between the two fixing plates 11, thereby making the cooperation between the third bolt assembly 12 and the fixing plates 11 generate tension on the covering plate 2, so that the covering plate 2 is pressed tightly against the corner of the speaker housing 1, resulting in a high degree of tightness in the connection between the covering plate 2 and the speaker housing 1.

[0025] It should be noted that the bolt assemblies in this application are all composed of hexagonal head screws or internal hexagonal head screws, nuts, and washers.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
