METHOD OF AND ARRANGEMENT FOR MANUFACTURING A PLASTIC DIAPHRAGM FOR AN ELECTROACOUSTIC TRANSDUCER

摘要

An arrangement (1) for and a method of manufacturing a plastic diaphragm (2) use a deep-drawing station (20) which has a deep-drawing die (33) of a sintered material, air present between the front surface (34) of the deep-drawing die (33) and the basic foil (10) which faces this front surface (34) is extracted through the deep-drawing die (33) via the particle-free interstices formed in the sintered material between the particles (60) coalesced by sintering.
