The invention relates to a diaphragm () for an ultrasonic transducer having a diaphragm body () which is made of metallic material and is provided on an outer surface region () with a coating (). In order to make it possible for the diaphragm surface to be provided with a particularly damage-resistant coating, the coating () has a transparent form such that the surface region () of the diaphragm body () is visible through the coating ().

Diaphragm and process for producing a diaphragm for an ultrasonic transducer

The invention relates to a sensor () for a short-range detection system and/or parking system of a motor vehicle, especially an ultrasound sensor. The sensor comprises a pot-shaped housing (), whereby the base thereof () is embodied as an oscillating membrane. The housing comprises a coating on at least the outer side. The invention is characterized in that the coating is made of powder () which is weather-proof, which can be coated and which has no or no significant negative influence upon the oscillation behavior of the membrane. The invention also relates to a method for the production of this type of sensor.
