The present invention relates to a diaphragm assembly. The diaphragm assembly is to provide an even damping force to whole areas of the diaphragm without increasing the area of a bobbin and a magnetic field circuit, by coupling a damper to a rod and not the bobbin. The diaphragm assembly includes a diaphragm; a bobbin which has a predetermined cross-section area and is coupled to the bottom of the diaphragm; a voice coil wound on the side of the bobbin; a rod which has a cross-section area which is larger than that of the bobbin and is coupled to the bottom of the diaphragm by the upper surface in order for the bobbin to be located on the inner side; and a damper which is coupled to the rod and elastically supports the rod. |
