Description

Technical Field

[0002] Linear array speakers are a group of closely spaced radiating units arranged in a straight line with the same amplitude and phase. Through linear transmission, the transmission distance is increased and the attenuation of sound transmission is reduced. Traditional linear array speakers are generally fixed, and most of the sites are large, making it difficult to produce the same sound effects at all angles. Therefore, the existing linear array speakers that are easy to adjust the angle have been continuously innovated and developed. It can be seen that the current linear array speakers basically meet people's needs, but there are still some problems.

[0003] For example, the patent document with the announcement number CN216491013U discloses: "A remote linear array speaker, including a hydraulic bending bracket, the hydraulic bending bracket includes a hydraulic bracket chassis, a hydraulic press is installed in the hydraulic bracket chassis, a bottom rotating shaft is fixedly connected to the top of the hydraulic bracket chassis, the bottom rotating shaft is movably connected to the hydraulic lifting column inside, and the hydraulic lifting column is movably connected to the hydraulic press, the top of the hydraulic lifting column is movably connected to the top rotating shaft, and the top rotating shaft is fixedly connected to the speaker array inside. The utility model converts the up and down movement of the hydraulic lifting column into the lateral movement of the speaker array by setting the hydraulic lifting column and the upper and lower rotating shafts, and at the same time, by remotely controlling the hydraulic press, the angle of the speaker can be adjusted according to the actual situation at the installation site, so that the speaker can be more adapted to the application occasion and the sound effect is improved". By converting the up and down movement of the hydraulic lifting column into the lateral movement of the speaker array, and the hydraulic bending bracket only drives the speaker unit at the top, the speaker array can be naturally bent into an arc to realize the function of a linear array speaker.

[0004] However, the speakers of the above-mentioned devices can generally only produce good sound effects within a certain angle range, and many scenes are large in scope, which makes it difficult for the speakers to produce the same sound effects for a large range of scenes. In addition, the array speakers are heavy and difficult to carry, and the speakers are difficult to move at any time when in use, resulting in the sound effects of the scene always remaining unchanged, making it difficult to create different interactive effects for people in different areas. Therefore, linear array speakers are needed to solve the above problems. Utility Model Content
