1. A low frequency underwater acoustic projector comprising:
- a power source;
at least one switching circuit for controlling said power source;
a first encapsulated spiral wound wire contiguous with a second encapsulated spiral wound wire;
wherein said first encapsulated spiral wound wire and said second encapsulated spiral wound wire are flexibly attached to an annular ring positioned around the seam of said first and second encapsulated spiral wound wires; and
said first and second encapsulated spiral wound wires are coupled to said power source through said switching circuit.

Abstract
A reusable low frequency projector system that is capable of producing coherent broadband, high power, low frequency acoustic pressure waves underwater. The projector has two halves each with a spiral wound insulated wire core. The spiral wound wires are separately encapsulated and then joined flexibly in a contiguous parallel orientation. When energized by a voltage source the encapsulated spiral wound wires are repelled from one another and then come back together when not energized, imparting a pressure wave to the water at a desired frequency. The projector requires no pressure compensation devices for operation.
