The present invention relates to a diaphragm assembly used in a speaker device. The diaphragm assembly according to the present invention comprises a vibration plane with the bottom surface coupled with a voice coil and the top surface generating a sound pressure; and a surround having an opening at the center, including a vibration plane coupling portion including a flat plane of the exterior of the opening and coupled with an outer region of the top surface of the vibration plane, a convex portion extending from the perimeter of the vibration plane coupling portion and formed to be convex upwards, and a frame coupling portion extending from the perimeter of the convex portion, including a flat plane, and coupling with a frame. The vibration plane includes a radiant heat blocking portion having at least some of the perimeter extending further than the perimeter of the vibration plane coupling portion to prevent some of radiant heat generated from the voice coil from being transferred to the surround. |
