[0031] See also Figure 1-3 A combined linear array speaker comprises a speaker housing 1 and an array component, wherein the array component is arranged on the side of the speaker housing 1.

[0032] An output end protective shell 2 is arranged on the front of the speaker housing 1, three positioning shaft seats 3 are arranged on the upper and lower sides of the speaker housing 1, another speaker housing 1 is installed through the positioning shaft seats 3, and array plates 5 are arranged on the left and right sides of the output end protective shell 2.

[0033] In this embodiment, the output end protection shell 2 is in a 160-degree arc shape, a plurality of small holes are opened on the outer surface of the output end protection shell 2 , and the array plate 5 is fixedly mounted on the side of the speaker housing 1 .

[0034] It should be noted that the arc-shaped design of the output end protective shell 2 can provide a wider protection range and effectively prevent external objects from directly impacting the internal structure of the speaker. At the same time, the material and structural design of the output end protective shell 2 also take durability into consideration and can withstand certain physical pressure and harsh environmental conditions.

[0035] The small holes on the outer surface of the output end protective shell 2 are helpful for the diffusion and uniform distribution of sound. These small holes can ensure that the sound can be smoothly transmitted from the inside of the output end protective shell 2, avoiding local aggregation or weakening of the sound, thereby providing a more uniform and wide sound field effect.

[0036] In this embodiment, the outer surfaces of the three positioning shaft seats 3 are provided with positioning angle bolts 9, and the positioning angle bolts 9 are fixedly installed on the upper and lower sides of the speaker housing 1. The inner sides of the three positioning shaft seats 3 are provided with threaded grooves 10, and the inner sides of the threaded grooves 10 can be threadedly connected with positioning threaded columns 6, and the positioning threaded columns 6 fix the upper and lower speaker housings 1.

[0037] It should be noted that, through the coordinated use of the positioning angle bolt 9 and the positioning shaft seat 3, the positioning of the speaker housing 1 is more precise, ensuring the stability of the speaker during installation and use. This stability helps to reduce distortion and fluctuations in sound transmission and improve sound quality.

[0038] The design of the thread groove 10 and the positioning thread column 6 makes the installation and removal of the speaker housing 1 simple and quick. By rotating the positioning thread column 6, the speaker housing 1 can be easily fixed and separated, thereby improving the maintenance efficiency and convenience of the equipment.

[0039] In this embodiment, a support base 8 is threadedly connected to the inner side of the lowest positioning shaft seat 3, and the support base 8 is tightly combined with the lowest positioning shaft seat 3 through a threaded connection, providing a stable support for the entire speaker system. This not only prevents the speaker from shaking or tipping over due to external force, but also ensures the stability of sound transmission and reduces the sound quality loss caused by vibration.

[0040] A wire guide tube 4 is fixedly installed at the center of two adjacent speaker housings 1 , and the wire guide tube 4 connects the upper and lower speaker housings 1 .

[0041] It should be noted that the design of the wire guide tube 4 enables the wires inside the speaker system to be managed and arranged in an orderly manner. By guiding the wires from the previous speaker housing 1 to the next one, the clutter and crossing of the wires are avoided, the neatness and reliability of the entire system are improved, and this also facilitates the maintenance and replacement of the wires.

[0042] The array component includes an array assembly 7, which is arranged between two adjacent array plates 5. The array assembly 7 fixes the upper and lower speaker housings 1.

[0043] In this embodiment, a clamping plate 11 is fixedly installed on the side surfaces of two adjacent array plates 5 , and the inner sides of the two clamping plates 11 are screwed to a common array fixing bolt 12 , which is in a U-shaped structure.

[0044] It should be noted that two adjacent array panels 5 are firmly connected together through the array fixing bolts 12 to form a stable structure. This connection method not only enhances the connection strength between the array panels 5, but also improves the structural stability of the entire speaker system, and helps to reduce deformation or looseness caused by vibration or external force.

[0045] The U-shaped structure of the array fixing bolt 12 makes the installation and disassembly process simpler and more convenient. The user only needs to fix the array fixing bolt 12 in the screw hole of the snap plate 11 to quickly fix the array plate 5. Similarly, when disassembling, the array fixing bolt 12 only needs to be taken out to easily separate the array plate 5, thereby improving work efficiency.

[0046] In this embodiment, the central section of the array fixing bolt 12 is clamped with an interlocking shaft 13, and the interlocking shaft 13 can divide the array fixing bolt 12 into two upper and lower parts. The two array fixing bolts 12 are each provided with an array assembly 7 at one end close to the interlocking shaft 13. The two array assemblies 7 are clamped on the inner side of the interlocking shaft 13, and the two array assemblies 7 are each provided with a limiting retaining ring 14 at one end away from the interlocking shaft 13.

[0047] It should be noted that the design of the interlocking shaft 13 makes the array fixing bolt 12 more stable and reliable when connected to the array plate 5. By dividing the array fixing bolt 12 into two parts, upper and lower parts, and using the interlocking shaft 13 for clamping, it can be ensured that the array fixing bolt 12 is not easy to loosen or break when subjected to external force, thereby enhancing the stability and reliability of the entire speaker system structure.

[0048] The arrangement of the array assembly 7 and the limit retaining ring 14 makes the installation and removal process more convenient and quick. Through simple clamping and fixing operations, the array plate 5 can be quickly installed and removed, thereby improving work efficiency.

[0049] The working principle of the above embodiment is:

[0050] The output end protective shell 2 on the front side of the speaker housing 1 is used to achieve effective sound propagation and protection.

A threaded groove 10 is provided on the inner side of each positioning shaft seat 3, which can be threadedly connected to the positioning threaded column 6. By rotating the positioning threaded column 6, the upper and lower speaker housings 1 can be firmly fixed together to form an integral array structure.

[0051] An array plate 5 is fixedly installed on the side of the speaker housing 1, and a clamping plate 11 is fixedly installed on the side of the array plate 5. The inner sides of the two clamping plates 11 are connected with a U-shaped array fixing bolt 12 by screws. The central section of the array fixing bolt is clamped with an interlocking shaft 13, which can divide the array fixing bolt 12 into two upper and lower parts. Through the cooperation of the array fixing bolt 12 and the array assembly 7, the array plate 5 can be easily and quickly installed and disassembled, while ensuring the stability and reliability of the connection between the upper and lower speaker housings 1.

[0052] The beneficial effects of the above embodiments are:

[0053] A 160-degree arc-shaped output end protective shell 2 is provided on the front of the speaker housing 1, so that the sound of the speaker can be evenly distributed within a wide horizontal angle, achieving wide horizontal coverage.
