ULTRASONIC SENSOR FOR A MOTOR VEHICLE, MOTOR VEHICLE, AND METHOD FOR PRODUCING AN ULTRASONIC SENSOR

摘要

The invention relates to an ultrasonic sensor (4) for a motor vehicle (1), with a pot-shaped membrane (8) having a membrane base (10) and a membrane lateral wall (9), wherein the membrane base (10) has a front side (12) pointing in a transmitting direction (11) of the ultrasonic sensor (4) and a rear side (13) opposite the front side (12), and the ultrasonic sensor (4) is designed to emit and/or receive ultrasonic signals via the membrane base (10), wherein a multiplicity of impressions (15) are formed in the membrane base (10) on the rear side (13) or on the front side (12) of the membrane base (10) and reduce a thickness (16) of the membrane base (10) at positions of the impressions (15). The invention also relates to a motor vehicle (1) and to a method for producing an ultrasonic sensor (4).
