Abstract
An ultrasound transducer has a housing, at least one piezoelectric element, and a membrane emitting or receiving ultrasound. A mass ring is arranged at an edge portion of the membrane for the dampening of undesirable resonances. To provide an ultrasound transducer with the smallest possible dimensions, the ultrasound transducer is configured as a lengthwise or longitudinal oscillator, the mass ring is separate from the membrane and is joined to both the edge portion of the membrane and the inside of the housing. A ring-shaped dampening element is attached to the inside of the housing and is located next to the mass ring.
