摘要：
A loudspeaker diaphragm comprising a molded, sintered ceramic body is described. The body is made of ceramic crystalline particles whose maximum size is below 1/5 time a thickness of the body which is in the form of a dome or cone. The dome- or cone-shaped diaphragm may have a flange along an opening side thereof in order to prevent deformation as may occur during firing.
