Abstract

The device has at least one piezoelectric element (16) between two clamp sections (12,14) and at least one clamp element (18) with which the piezoelectric element is biased by the clamp sections. The clamp element is in the form of an annular clamping spring with at least one peripheral recess (22,24) in its wall. Independent claims are also included for the following: a clamp element for an ultrasonic transducer.
