An ultrasonic transducer having a pot-like casing has an outer bottom face which is designed in part as a vibrating diaphragm. A stabilizing ring is arranged on the outside of the wall of the pot-like casing, imparting a greater rigidity to the casing and limiting the ultrasonic vibration essentially to the bottom of the pot as a vibrating diaphragm. The propagation and reception beams of the ultrasonic waves can be shaped further by an additional arrangement of a sound directing device in the area of the vibrating diaphragm.
