Abstract

The invention belongs to the technical field of sound equipment, and relates to noise reduction type sound equipment. The invention comprises an acoustic body, an elastic protection plate and a bottom block. The two ends of the elastic protection plate are mutually far away so that the elastic protection plate is stored on the sound body. The bottom block is arranged at the bottom of the sound body in a sliding way. The elastic protection plate is outwards bulged and deformed, and the bottom block outwards moves to enlarge the supporting area of the bottom of the sound body. Enclose into sealed space between roof, bottom block, sound body and the elastic protection board, when the elastic protection board received the striking, the elastic protection board was cushioned the striking, was favorable to keeping sound body's stability. And simultaneously when the elastic protection plate is collided and deformed, the air in the sealing space enters into the abdication cavity, so that the second piston plate pulls the first piston plate, negative pressure is generated in the negative pressure cavity, the bottom block is further adsorbed on the ground, and the sound body is further prevented from toppling.
