摘要：An ultrasonic sensor includes a housing having a peripheral side wall and a basesurface, i.e., it is configured as essentially pot-shaped. The base surface is configured as a
diaphragm. A transducer element, which is configured as a piezoelectric element, forexample, and is used for generating and detecting ultrasonic oscillations, is situated onthe base surface. At least one mass element is situated on the base surface so that theresistance of the mass element against an oscillation of the diaphragm increases withrising oscillation frequency.
