Description

Technical Field

[0001] This utility model relates to the field of speaker design, and in particular to an angle-adjustable line array speaker. Background Technology

[0002] A line array speaker is a group of closely spaced radiating units arranged in a straight line, with identical amplitude and phase. Commercially available speakers require angle adjustment during installation based on the site conditions before being secured to their corresponding mounting positions with screws.

[0003] However, most line array speakers consist of multiple speakers, each with a different angle. To complete the on-site arrangement and installation of the speakers, the operators need to adjust and lock them according to the site conditions. Since existing speakers do not have the function of initially defining the angle, and the speakers are very heavy, the angle of the speakers is easy to change before the screws are locked, which affects the installation efficiency. In addition, it is difficult to change the fixed angle of existing speakers after they are installed and locked, which makes them inconvenient to use.

[0004] Therefore, it is necessary to design a structure that can quickly limit the installation angle to achieve preliminary positioning for use in line array speakers. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0006] An angle-adjustable line array speaker includes a speaker enclosure. The middle of the left and right sides of the speaker enclosure is formed with recessed grooves. A rotation limiting block is fixedly installed in the recessed groove. The outer edge of the rotation limiting block is circular. A rotation block is provided on the side of the rotation limiting block. A mounting circular hole is formed on the rotation block. The rotation limiting block is clearance-fitted into the mounting circular hole.

[0007] The outer side of the rotating limiting block is formed with a T-shaped slot. A limiting spring is installed in the T-shaped slot with a clearance fit. The two ends of the limiting spring are respectively snapped into the two sides in the T-shaped slot. An elastic element is installed between the middle of the T-shaped slot and the limiting spring.

[0008] The mounting hole has several limiting grooves formed inside, and the elastic element drives the limiting spring to be stuck in one of the limiting grooves to limit the angle.

[0009] Furthermore: a limiting plate is fixedly installed on the outer side of the rotating limiting block, and the limiting plate covers the mounting hole and several limiting grooves.

[0010] Furthermore, several raised rings are evenly arranged on the outer side of the rotating limiting block, and the limiting plate is locked to the raised rings by screws.

[0011] Furthermore, several of the aforementioned limiting grooves are arranged in a circular array within the mounting hole.

[0012] Furthermore: the middle part of the limiting spring is bent into a U-shaped structure, and both ends of the limiting spring are bent outward to form right angle edges, which are correspondingly snapped into the two sides of the T-shaped slot.

[0013] Furthermore: the elastic element is a compression spring, and a spring groove is formed in the middle of the T-shaped slot, with the inner end of the elastic element abutting in the spring groove.

[0014] Furthermore: countersunk grooves are formed at all four ends of the recessed groove, and four positioning rings are formed on the side of the rotating limiting block near the recessed groove. The positioning rings are installed in the countersunk grooves with a gap fit, and the positioning rings are locked in the countersunk grooves by screws.

[0015] Furthermore: a positioning cylinder is formed in the center of the recessed groove, and a cylindrical through hole is formed in the center of the rotating limiting block. The positioning cylinder is fitted into the cylindrical through hole with a clearance fit.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. A rotating block is installed on the speaker cabinet. The rotation is limited by the cooperation between the rotating block and the limiting block. Specifically, the limiting spring is driven by an elastic element to lock into one of the limiting slots to limit the rotation angle of the speaker cabinet. Then, screws are used to lock the speaker cabinet. Because of the structure that initially limits the angle, there is no need to repeatedly determine the installation angle when locking the screws. This is especially useful for line array speakers, which has higher installation efficiency.

[0018] 2. The locking force when locking the speaker cabinet can be adjusted. When it is not completely locked, the angle can be adjusted by rotating it for convenient use. When it is completely locked, it cannot be rotated anymore, ensuring high stability.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figure 1-5 As shown, the present invention provides an angle-adjustable line array speaker, including a speaker cabinet 1. The middle of the left and right sides of the speaker cabinet 1 is formed with recessed grooves 2. A rotation limiting block 3 is fixedly installed in the recessed groove 2. The outer edge of the rotation limiting block 3 is circular. A rotation block 4 is provided on the side of the rotation limiting block 3. A mounting circular hole 5 is formed on the rotation block 4. The rotation limiting block 3 is fitted into the mounting circular hole 5 with clearance fit.

[0033] The outer side of the rotating limiting block 3 is formed with a T-shaped slot 6. A limiting spring 7 is installed in the T-shaped slot 6 with clearance fit. The two ends of the limiting spring 7 are respectively snapped into the two sides in the T-shaped slot 6. An elastic element 8 is installed between the middle part of the T-shaped slot 6 and the limiting spring 7.

[0034] The mounting hole 5 has several limiting grooves 9 formed inside, and the elastic element 8 drives the limiting spring piece 7 to be stuck in one of the limiting grooves 9 to limit the angle.

[0035] The principle is as follows: A rotatable rotating block 4 is set on the speaker cabinet 1. The rotation is limited by the cooperation between the rotating limiting block 3 and the rotating block 4. Specifically, the elastic element 8 drives the limiting spring 7 to lock in one of the limiting grooves 9 to limit the rotation angle of the speaker cabinet 1. Then, the speaker cabinet 1 is locked with screws. Because of the structure that initially limits the angle, there is no need to repeatedly determine the installation angle when locking the screws. Especially for line array speakers, its installation efficiency is higher.

[0036] This utility model can adjust the locking force when locking the speaker enclosure 1. When it is not completely locked, the angle can be adjusted by rotation, which is convenient for actual use. When it is completely locked, it cannot be rotated anymore, and the stability is high.

[0037] Furthermore, a limiting plate 10 is fixedly installed on the outer side of the rotating limiting block 3, and the limiting plate 10 covers the mounting circular hole 5 and several limiting grooves 9; so that the rotating block 4 is stably installed and will not fall out of the rotating limiting block 3 when adjusting the angle, thereby realizing the quick installation of the speaker cabinet 1.

[0038] Furthermore, several raised rings 11 are evenly arranged on the outer side of the rotating limiting block 3, and the limiting plate 10 is locked to the raised rings 11 by screws; so that a rotation gap is maintained between the limiting plate 10 and the rotating block 4, making the rotation adjustment smoother and more stable.

[0039] Furthermore, several of the aforementioned limiting grooves 9 are arranged in a circular array within the mounting holes 5; they can automatically lock after rotating a certain angle, which facilitates the angle limitation of the speaker cabinet 1.

[0040] Furthermore: the middle part of the limiting spring 7 is bent into a U-shaped structure 81, and both ends of the limiting spring 7 are bent outward to form right angle edges 82. The right angle edges 82 are correspondingly snapped into the two sides in the T-shaped slot 6; making the installation of the limiting spring 7 more stable and preventing it from falling off the T-shaped slot 6.

[0041] Furthermore, the elastic element 8 is a compression spring, and a spring groove 12 is formed in the middle of the T-shaped slot 6, with the inner end of the elastic element 8 resting in the spring groove 12; making the installation of the elastic element 8 more stable.

[0042] Furthermore: countersunk grooves 13 are formed at all four ends of the recessed groove 2, and four positioning rings 14 are formed on the side of the rotating limiting block 3 near the recessed groove 2. The positioning rings 14 are installed in the countersunk grooves 13 with a gap fit, and the positioning rings 14 are locked in the countersunk grooves 13 by screws; making the installation of the rotating limiting block 3 in the recessed groove 2 more stable.

[0043] Furthermore: a positioning cylinder 15 is formed in the center of the recessed groove 2, and a cylindrical through hole 16 is formed in the center of the rotating limit block 3. The positioning cylinder 15 is fitted into the cylindrical through hole 16 with clearance fit; this can effectively prevent the rotating limit block 3 from tilting when the speaker cabinet 1 is suspended and bearing weight, and ensure the stable installation and locking of the rotating limit block 3 in the recessed groove 2.

[0044] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
