Abstract (en)
[origin: WO2011009513A1] The invention relates to a diaphragm (1) for an ultrasonic transducer having a diaphragm body (2) of metallic material, which is provided with a coating (10) on an outer surface region (5; 8). In order to enable the in particular damage-resistant coating of the diaphragm surface, the coating (10) is designed to be transparent such that the surface region (5; 8) of the diaphragm body (2) is visible through the coating (10).
