Loudspeaker device

The utility model discloses a loudspeaker device. The loudspeaker device comprises a peripheral frame and a loudspeaker monomer which is accommodated in the peripheral frame. The loudspeaker monomer comprises a diaphragm. The diaphragm comprises an edge part which is located at the edge. The edge part is a structure which protrudes upward. The peripheral frame comprises a cover body which is located on the upper side of the diaphragm. A first step-shaped structure is arranged on the outer surface of the cover body. A second step-shaped structure which is corresponding to the first step-shaped structure is arranged on the side, which is close to the diaphragm, of the cover body. The second step-shaped structure is provided with a first plane which is relatively close to the diaphragm and a second plane which is relatively far away from the diaphragm. A concave avoiding part is arranged on the position, which is corresponding to the edge part, on the first plane. The structure can prevent the collision between
