A compound electro-acoustic transducer for producing acoustic signals has a plurality of elements. Each element has a piezoelectric disk with electrically conductive plates fixed on the top and bottom sides of the piezoelectric disk. A stud is joined to an outer face of each plate. Conductors can be joined to each stud. The elements can be assembled on a resilient structure to form an array. Elements can be used in the array or individually accessed.

A mount for acoustic transducers has a resilient sheet with a plurality of mounting apertures therein. Each mounting aperture has an annular groove formed about the inside surface of the sheet to accommodate one of the acoustic transducers. A pair of rigid, acoustically transparent plates are mounted on each side of the resilient sheet. Each plate has a plurality of communication apertures in it which correspond to the mounting apertures of the resilient sheet. The acoustic transducers are inserted into the mounting aperture of the resilient sheet. The acoustically transparent plates provide structural support for the mount.
