A method of manufacturing a diaphragm for an electroacoustic transducer which operates in accordance with the electrodynamic principle and has portions with different thicknesses made from a thermoplastically deformable material having a constant thickness, wherein, in a first work step, that portion of the diaphragm material which is to have the greater thickness in the finished diaphragm, is held by an inner positioning device, while the remaining area of the diaphragm is additionally held by an outer positioning device, and the remaining area of the diaphragm is pulled or stretched with the influence of tension and heat to reduce the thickness thereof. In a second workstep, the entire diaphragm is thermoplastically stamped in a mold.
