Background Along with increasing importance of society on noise pollution problem, the soundproof curtain is widely used as an important auxiliary device for building soundproof in environments such as office places and video and audio rooms which need acoustic control. The traditional soundproof curtain adopts a mode of increasing the thickness of the curtain body or arranging a plurality of layers of sound absorbing materials to improve the soundproof performance, but has obvious defects in practical use. In the prior art, the sound insulation curtain is usually opened and closed through a sliding rail, but a certain movable gap is required to be kept at the connecting part of the curtain body and the sliding rail, so that a sound leakage channel is easy to form between the edge of the curtain body and the rail in the unfolded state of the curtain. Such structural gaps can significantly impair the overall sound-insulating effect, particularly during the propagation of medium-high frequency sound waves. Part of the improvement schemes attempt to add sealing structures at the track, but the problems of increased curtain moving resistance, easy abrasion of parts and the like are often caused, and the sound insulation performance and the use convenience are difficult to be considered.
