ABSTRACT:
The present invention relates to an underwater acoustic projector compris a housing formed from a rigid material, a fixed plate secured to the housing, first and second annular electrostrictive rings positioned on one side of the fixed plate, and third and fourth annular electrostrictive rings positioned on a second side of the fixed plate. The first and second annular rings are separated by a first moving plate, while the third and fourth annular rings are separated by a second moving plate. Each moving plate is connected to a drive piston which contacts an inner surface of an outer housing surrounding the inner housing. The outer housing is caused to move in a flexural mode by the drive pistons in contact with it. The annular rings are formed from lead magnesium niobate or lead magnesium niobate-lead titanate and are wired for dual push-pull operation to reduce the non-linearity of the response of the annular rings.
