Abstract
A method of manufacturing a sonar projector is disclosed. The method comprises the steps of: bonding a flat piezo-ceramic plate to a flexible conducting sheet; dicing the plate to form an assembly comprising a matrix of piezo-ceramic pegs bonded to the flexible conducting sheet, the pegs being separated by kerfs; bending the assembly to a predetermined curvature, thereby expanding the kerfs; filling the expanded kerfs with a filler material; and applying conductive material to the exposed surfaces of the pegs, such that the conductive material and the flexible conducting sheet in combination form electrodes operable to apply a voltage to the piezo-ceramic pegs. Methods of manufacturing a curved piezo-ceramic structure are also disclosed.
