Active indoor noise shielding system
The invention relates to the technical field of noise shielding, in particular to an active indoor noise shielding system which comprises a track, a transmission component, an adjusting component and an active noise shielding component. The active noise shielding component comprises a sound amplifying cover, and a first lead screw is arranged on the inner side of the sound amplifying cover; a guide sliding rod is arranged at the position, close to the first lead screw, of the inner side of the sound amplifying cover, and a sound output component is installed on the outer side of the first lead screw. The transmission component slides on the upper side of the track to adjust the shielding position, noise shielding operation in the local direction of a building can be completed, each noise shielding system can operate independently, sound output by the sound output component is diffused through the sound amplifying cover, and the noise shielding effect is improved. The noise collector detects noise in the direction where the noise collector is located and adjusts the position of the sound output component, the accuracy of the sound transmission direction is improved, the height and angle of the active noise shielding component are adjusted through the adjusting component, and the convenience of noise elimination angle adjustment is improved.
本发明涉及噪声屏蔽技术领域，具体是一种主动式室内噪声屏蔽系统，包括轨道、传动构件、调节构件与主动式噪声屏蔽构件，所述主动式噪声屏蔽构件包括扩音罩，所述扩音罩的内侧设置有第一丝杆，所述扩音罩的内侧临近第一丝杆的位置处设置有导滑杆，所述第一丝杆的外侧安装有声音输出构件。本发明通过传动构件在轨道的上侧滑动进行屏蔽位置的调节，能完成建筑局部方向的噪声屏蔽操作，每个噪声屏蔽系统能独立运行，通过扩音罩对声音输出构件输出的声音扩散，通过噪声采集器对所在方向的噪声检测并调节声音输出构件的位置，提高声音传播方向的精准度，通过调节构件调节主动式噪声屏蔽构件的高度与角度，提高消声角度调节的便捷度。
