ABSTRACT:
An energy coupling for piezo-electric crystals and mounting for the crystals wherein the crystal is flexibly edge mounted and isolated from a rigid holder and is backed by a flexible and compressible conductor to which selected frequency energy is transmitted having an adjustable compression plate therebehind for maintaining proper energy transmitting contact between the crystal and conductor for production of a collimated sound beam from the face of the crystal from a plurality of electrodes on the back face of the crystal. The system provides for energy transmission with no possibility of isolation at any frequency other than at the desired frequency of transmission.
