Suspension type sound reflecting cover
The invention discloses a sound reflecting cover for a stage. The top plate, the side plates and the back plate of the sound reflecting cover are all hung on the stage top, are put down when in use and are hung up when not in use. Due to suspension installation, the sound reflecting plate structure can be made simple and light. A top plate and side plates of the sound reflecting cover are of folding structures and are hung on the upper portion of the stage through steel cables. The top plate and the side plates are suspended through the lifting steel cables and the positioning steel cables, the positioning steel cables are used for determining the suspension positions of the top plate and the side plates, and the lifting steel cables play roles in folding the top plate and storing the top plate. The hoisting steel cable is fixed on a stage suspender, and the stage suspender is used for lifting the sound reflecting cover.
一种舞台使用的反声罩。反声罩的顶板、侧板和背板都吊装在舞台顶上，使用时放下，不使用时吊起。由于悬吊安装，反声板结构可以做的简单轻巧。反声罩顶板和侧板都采用折叠结构，使用钢索悬吊在舞台上部。顶板和侧板都起吊钢索和定位钢索悬吊，定位钢索是确定顶板和侧板的悬吊位置，起吊钢索是起作折叠顶板和收储的作用。起吊钢索固定在舞台吊杆上，使用舞台吊杆升降反声罩。
