Variable MLS sound absorbing diffuser
The invention relates to a sound absorption and diffusing reflector, in particular a variable MLS sound absorption diffuser. The variable MLS sound absorption diffuser is provided with an upper baffle, a lower baffle, a left side baffle, a right side baffle, a first panel layer, a second panel layer and a sound absorption layer. The upper baffle, the lower baffle, the left side baffle and the right side baffle form a rectangular frame, the first panel layer and the second panel layer are arranged on the front and rear layers inside the rectangular frame respectively, the first panel layer is the same as a first panel layer of a common MLS diffuser, and the top and the bottom of the first panel layer are fixed to the upper baffle and the lower baffle respectively. The second panel layer is composed of at least two longitudinal fixed panels and at least one longitudinal movable panel. Narrow gaps are formed between the longitudinal fixed panels and the longitudinal movable panels. The tops and the bottoms of the longitudinal fixed panels are fixed to the upper baffle and the lower baffle respectively, and the tops and the bottoms of the longitudinal movable panels are arranged inside a movable track of the upper baffle and a movable track of the lower baffle respectively, and the longitudinal movable panels can move left and right along the movable tracks. The sound absorption layer is arranged inside the rectangular frame and tightly attached to the back face of the second panel layer. A cavity is formed in the back face of the sound absorption layer.
