Piezoelectric telephone capsule

摘要

The invention relates to a piezoelectric telephone capsule with a mounting body (24). This mounting body (24) performs a plurality of functions. It serves to carry a piezoelectric diaphragm (21) and also to press a soldering tag (60), with which an earth connection is established between a printed circuit board (34) and a metal housing (2) of the telephone capsule (1), tightly against this metal housing (2). Furthermore, this mounting body (24) is designed in such a way that it surrounds the printed circuit board (34) in a circular form, thus allowing a space-saving arrangement of the printed circuit boards in the metal housing (2). <IMAGE>
