Abstract

A magnetostrictive transducer apparatus (4) for ultrasonic cleaning applications with a magnetostrictive material portion (18) of stacked laminations bonded to a cou­ pling member (16) made of non-magnetic material such as aluminum for operation at a frequency of about 40 kilohertz and a sound level below 90 DBA, with each of the stacked lamina­ tions (18) and the coupling member (16) being of about one-half wavelength at the desired frequency of operation.
