Abstract:
An underwater sound source includes an acoustical driver, a controller of the acoustical driver, and a resonant tube acoustically coupled to the acoustical driver. The resonant tube has a pair of slotted portions, in which each slotted portion is disposed along the length of the resonant tube at a location corresponding to a node of a harmonic of the resonant tube. The sound system is configured to emit an output signal within a bandwidth defined by a dual resonance characteristic of the resonator tube. The sound source may also include a pair of coaxial tubular sleeves disposed around the resonant tube, each sleeve configured to slidably cover one of the slotted portions, and tune the resonance frequency of the tube over a wide range. At a high frequency end, when slots are uncovered, the frequency response of the resonant tube obtains a dual-resonant form.

Claim (Index 12):
An underwater sound system, comprising:\n an underwater sound source, comprising:\n an acoustical driver; \n a controller of the acoustical driver; \n a resonator tube acoustically coupled to the acoustical driver, wherein the resonator tube further comprises:\n a first slotted portion comprising a first at least two co-radial resonator slots; and \n a second slotted portion comprising a second at least two co-radial resonator slots, \n wherein a total length of the resonator tube defines a plurality of harmonics of the resonator tube, \n wherein the first slotted portion is located at a position along the total length of the resonator tube corresponding to a first node of one of the plurality of harmonics, \n wherein the second slotted portion is located at a position along the total length of the resonator tube corresponding to a second node of one of the plurality of harmonics; and \n \n a first coaxial tubular sleeve and a second coaxial tubular sleeve,\n wherein the resonator tube is disposed within the first coaxial tubular sleeve thereby forming a first gap between a first portion of an exterior surface of the resonator tube and an interior surface of the first coaxial tubular sleeve, \n wherein the resonator tube is disposed within the second coaxial tubular sleeve thereby forming a second gap between a second portion of the exterior surface of the resonator tube and an interior surface of the second coaxial tubular sleeve, and \n wherein the first coaxial tubular sleeve is configured to slide upon the first portion of the exterior surface of the resonator tube and the second coaxial tubular sleeve is configured to slide upon the second portion of the exterior surface of the resonator tube, \n \n wherein the underwater sound source is configured to operate in a first acoustic mode when the first slotted portion is covered by the first coaxial tubular sleeve and the second slotted portion is covered by the second coaxial tubular sleeve, and \n wherein the underwater sound source is configured to operate in a second acoustic mode when the first slotted portion is uncovered by the first coaxial tubular sleeve and the second slotted portion is uncovered by the second coaxial tubular sleeve; \n a transmission comprising a lead screw in mechanical communication with the first coaxial tubular sleeve and the second coaxial tubular sleeve; a motor in mechanical communication with the transmission and configured to impart a rotary motion to the lead screw, thereby moving the first coaxial tubular sleeve and the second coaxial tubular sleeve; and a water pressure housing, wherein an exterior surface of the water pressure housing is in mechanical communication with the transmission and the motor, and wherein an interior of the water pressure housing is configured to contain one or more electrical components configured to control and power the motor.
