ABSTRACT:
A loudspeaker diaphragm affixed with a coil includes an edge portion located outside of a portion affixed with the coil and a center portion located inside of the portion affixed with the coil. The center portion is provided thereon with ribs. With these ribs, the height of the center portion can be limited to the height of the ribs. Therefore, it is possible to save a space of a loudspeaker where the loudspeaker diaphragm is placed, thereby slimming down the loudspeaker. Furthermore, with these ribs, the rigidity of the center portion can be improved without using a conventional solution of forming, for example, a dome shape on the center portion.
