LOUDSPEAKER

摘要

A loudspeaker includes a diaphragm body having a dome shape protruding upwardly, a magnetic circuit disposed below the diaphragm body, a voice coil coupled to the diaphragm body, an edge coupled to an outer circumference of the diaphragm body, and a frame coupled to the edge. The edge includes a first coupling portion provided at an outer circumference of the edge, a second coupling portion provided at an inner circumference of the edge and coupled to an outer circumference of the diaphragm body, and a roll portion disposed between the first coupling portion and the second coupling portion. The edge has a surface facing downward. The frame has a connecting surface disposed below the second coupling portion and coupled to the surface of the edge at the first coupling portion of the edge. This loudspeaker can decrease distortion of sound.
