PROBLEM TO BE SOLVED: To obtain a prescribed acoustic effect during use, prevent a sound reflector from unnecessarily swinging during movement and prevent the displacement from being generated between the right and left ends of the sound reflector. SOLUTION: The sound reflector system has a front sound reflector 10 facing the seat G side on a stage S, right and left sound reflectors 20 horizontally swingably connected to the right and left ends of the front sound reflector 10 and a ceiling sound reflector 30 raisably connected to the upper end of the front sound reflector 10. The top of the front sound reflector 10 is connected to a pair of rails 1 extended from the depth side of a stage S to a seat G side above the right and left sides of the stage S.
