The respective outer peripheries of two cone-shaped diaphragm base materials having different half apex angles are bonded to each other and joined to the inner periphery of a common edge member, and Among the diaphragm substrates, the diameter of the inner periphery of the diaphragm substrate on the back side with the smaller half apex angle is made larger than the diameter of the voice coil bobbin to reduce the height, and the inner periphery of the diaphragm substrate is A spacer is interposed between the part and the bobbin of the voice coil to provide a gap having a wedge-shaped cross section between the two diaphragm base materials, and the edge member is attached to the diaphragm having a structure in which the gap is filled with a core material. A speaker characterized in that the speaker is held in a frame through a frame. 2. The speaker according to claim 1, wherein the core material is a sheet of paper or the like folded in a zigzag manner in a circumferential direction and in a radial direction in a wedge shape. 3. The speaker according to claim 1, wherein the core material is a honeycomb core material.
