Abstract
An acoustic transducer design having a slotted oval-shaped shell and active transducer elements located on the inner surface of the shell is disclosed. The design provides a high power, ultra-low frequency oval projector having a number of applications, including underwater seismic prospecting and fish mitigation.
Claims11
A method of manufacturing an acoustic transducer that is configured to produce low frequency acoustic energy, comprising:
- providing a projector shell having an oval cross-section with a short axis and a long axis, a slot opening on the short axis, and an outer diameter of at least 18 inches along the short axis;
- and
- disposing a plurality of active transducer elements in a groove along the internal surface of the projector shell;
- wherein the transducer elements are adapted for coupling to a power source and the acoustic transducer operates in the frequency range under 400 Hz.
