Abstract: The present invention is directed to a method for producing a diaphragm for highly brittle metals used in loudspeakers, comprising a step of making a laminated plate by stacking a plate of superplastic material on a plate of highly brittle metal. The laminated plate is arranged on a mould, and the laminated plate is heated to a predetermined range of temperatures, determined according to the highly brittle metal. Subsequently, the laminated plate is deformed by pressuring the laminated plate in the mould, at the range of temperatures. Thus, a diaphragm can be formed from a plate of highly brittle metals, without causing brittle fracture or generating internal or surface defects.
