Description

Technical Field

[0001] The utility model relates to the technical field of linear array speakers, in particular to a linear array speaker with stable angle adjustment. Background Technique

[0002] A linear array speaker is a common and important audio device in a large audio system. The characteristic of a linear array speaker is that the projection of its sound has strong directivity and consistency. By combining multiple speaker units in a linear arrangement, it can achieve sound propagation over a longer distance and maintain uniform sound coverage and clarity in a larger space. For example, in large outdoor music festivals, stadiums, theaters and other places, linear array speakers can provide high-quality sound experiences for audiences. It can effectively solve the problems of sound attenuation and scattering during the propagation process, enabling distant listeners to also feel clear and full sound.

[0003] The Chinese patent with the publication number CN218071672U discloses an angle-adjustable linear array speaker. When the angle of the linear array speaker body needs to be adjusted, the motor is turned on. When the motor is turned on, it drives the rotation of the rotating rod. When the rotating rod rotates, it drives the synchronous rotation of the linear array speaker body. When the linear array speaker body rotates to the required angle, the motor can be turned off.

[0004] However, in the above-mentioned prior art, no mechanism for stabilizing the angle of the speaker is provided. Since the linear array speaker is usually vertically suspended on the built stage frame, after the motor drives the speaker to rotate to the required angle, the position of the speaker may be affected by external factors and thus change the angle.

[0005] Therefore, in order to solve such problems, we propose a linear array speaker with stable angle adjustment. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a linear array speaker with stable angle adjustment, aiming to solve the problem that the existing adjustment method of the motor cannot maintain stability after adjusting the angle of the speaker to the preset position in the above-mentioned background technique.

[0007] To achieve the above object, the utility model adopts the following technical solutions: A linear array sound box with stable angle adjustment, including a stage rack and a buckle installed on one side of the stage rack. There are multiple groups of buckles. One end of the buckle is movably connected with a height adjustment mechanism. The side of the height adjustment mechanism away from the stage rack is fixedly connected with an angle adjustment mechanism. The side of the angle adjustment mechanism away from the height adjustment mechanism is fixedly connected with a sound box. The angle adjustment mechanism includes a group of connecting blocks and an adjustment block installed between the connecting blocks. One side of the connecting block is fixedly connected with the height adjustment mechanism. An arc-shaped groove is opened on the adjustment block. An arc-shaped plate is movably connected in the arc-shaped groove. Both ends of the arc-shaped plate are fixedly connected with the sound box. A plurality of threaded holes are penetrated through the side of the adjustment block close to the height adjustment mechanism. Screws are arranged in the threaded holes. The other end of the screw is threadedly connected with the arc-shaped plate.

[0008] Preferably, a plurality of circular through holes are opened on the arc-shaped plate, and the circular through holes are matched with the screws.

[0009] Preferably, semi-circular grooves are opened on both the upper and lower sides of the buckle.

[0010] Preferably, the height adjustment mechanism includes a housing and a cylindrical tube arranged inside the housing. One end of the housing away from the stage rack is fixedly connected with the connecting block, and the cylindrical tube is matched with the semi-circular groove.

[0011] Preferably, a spring is arranged between the housing and the cylindrical tube. One end of the spring is fixedly connected with the inner wall of the housing, and the other end of the spring is fixedly connected with the cylindrical tube.

[0012] Preferably, a protective cover is arranged on the outer side of the sound box.
