ABSTRACT:
An ultrasonic sensor with a cylinder-shaped housing whose base forms a diaphragm of the ultrasonic sensor. The diaphragm is manufactured as an independent component and directly mounted in the cylinder-shaped housing. A method for manufacturing the ultrasonic sensor includes the steps of manufacturing the diaphragm and the cylinder-shaped housing separately from each other, and mounting the diaphragm directly in the cylinder-shaped housing.
