Description

Technical Field

[0001] The utility model relates to the technical field of stage speakers, and specifically discloses an installation mechanism for a linear array speaker for the stage. Background Technique

[0002] A linear array speaker is a professional audio system with unique acoustic characteristics and application advantages. A linear array speaker consists of multiple speaker units, and these speakers are usually arranged in a straight line. Its main characteristics include: a powerful sound pressure level and long-distance projection ability: it can evenly cover the sound in a large venue and is suitable for occasions such as large-scale performances, stadiums, and outdoor music festivals; good directivity control: it can project the sound more precisely to a specific area, reduce the scattering and reflection of the sound, and improve the clarity of the sound.

[0003] A stage audio installation structure disclosed in Chinese Patent CN211209869U includes a mounting plate. An installation groove is opened at the bottom of the mounting plate. A threaded rod is movably connected to the inner wall of the installation groove. One end of the threaded rod is fixedly connected to a support column. A suction cup is fixedly connected to the bottom of the support column. A universal wheel is fixedly connected to the bottom of the mounting plate. A chute is opened at the top of the mounting plate. A first telescopic sleeve is fixedly connected to the inner wall of the chute. A shock-absorbing spring is fixedly connected to the inner wall of the first telescopic sleeve. A first telescopic rod is movably connected to the inner wall of the first telescopic sleeve. One end of the first telescopic rod is fixedly connected to one end of the shock-absorbing spring. This stage audio installation structure can achieve the purpose of good shock absorption effect.

[0004] During the use of the stage audio installation structure disclosed in the above document, when installing the stage audio through it, it is difficult to firmly fix the stage audio inside it, resulting in the stage audio being prone to detachment from it. And after installing the stage audio, it is difficult to change the angle of the stage audio according to the use requirements, resulting in an increase in the use difficulty of the stage audio due to the inability to adjust the angle. Therefore, an installation mechanism for a linear array speaker for the stage is needed to solve this problem. Content of the Utility Model
