Abstract:
An ultrasonic sensor, including a diaphragm cup, a housing and a decoupling element, the diaphragm cup and housing having a lateral surface, the decoupling element being at least partially made from an elastic material and having a continuous recess bounded by an inner wall of the decoupling element, the diaphragm cup and/or the housing being at least partially situated in the recess. To prevent sound being transmitted through a gap between the diaphragm cup and the decoupling element and/or between the housing and the decoupling element, the inner wall of the decoupling element is tautened by the contraction of elastic material at least around an area of the lateral surface of the diaphragm cup, circumferentially surrounding the diaphragm cup and/or the housing, and/or a lacquer layer applied on the lateral surface of the diaphragm cup, and/or the lateral surface of the housing so that the inner wall in this area rests flush against the lateral surface of the diaphragm cup and/or the lacquer layer applied on the lateral surface of the diaphragm cup and/or the lateral surface of the housing.
