ABSTRACT:
An acoustic transducer comprised of a resonator, an acoustic energy generating means, such as one or more piezoelectric crystals, and a bonding layer comprised of indium or tin for attaching the acoustic energy generating means to the resonator. The resonator comprises a material selected from the group consisting of quartz, sapphire, silicon carbide, silicon nitride, aluminum, ceramics and stainless steel. The resonator may form a detachable part of a container or the acoustic energy generating means may be attached directly to a side or to the bottom of the container, in which case a part of the container acts as the resonator.
