ULTRASONIC RESONATOR WITH SLOT OF NON-UNIFORM WIDTH

摘要

An ultrasonic resonator, for example a sonotrode, comprises a resonant body having an input face (12), an output face (13) and one or more slots (22) that extend through the resonant body substantially perpendicular to the longitudinal axis thereof. The slots (22) are of non-uniform width, to increase the efficiency of the sonotrode.
