Abstract (en)
[origin: WO0163595A1] The invention relates to an ultrasound sensor, especially for parking aids in motor vehicles, comprising a pot-shaped oscillating element (4). The bottom of said element serves as a membrane. According to the invention, at least two disc-shaped piezoelectric transducers (6, 7) are fixed next to one another in the membrane (5). The inventive ultrasound sensor is characterised by a sound directional diagram being provided with particularly high asymmetry.
