Abstract

A transducer includes a supporting body and a suspended structure mechanically coupled to the supporting body. The suspended structure has a first and a second surface opposite to one another along an axis, and is configured to oscillate in an oscillation direction having at least one component parallel to the axis. A first piezoelectric transducer is disposed on the first surface of the suspended structure, and a second piezoelectric transducer is disposed on the second surface of the suspended structure.
