A diaphragm assembly according to the present invention comprises: a diaphragm for generating sound pressure by means of vibration; and an edge, which is made from an elastic material and has one side coupled to the diaphragm and has the other side coupled to a fixing end, wherein the diaphragm comprises: a diaphragm plane generating sound pressure by means of vibration, and having a rim; an extending part formed by extending outwards from at least a portion of the diaphragm plane; and a coupling part formed at the end of the extending part and coupled to the fixing end. One side of the edge is coupled to the rim of the diaphragm plane. The extending part and/or the coupling part is not formed at a long-axis portion. |
