Title: Aquatic sound generating system for fishing lures

Abstract: The present invention is for fishing lures having a variable pressure diffuser system for generating a particular frequency simulating aquatic sounds. As a fishing lure is pulled through the water, water flows through an entrance venturi into a fluidic diffuser chamber. Also connected to the fluidic diffuser chamber, perpendicular to the normal direction of flow of the fluid, are two control channels. From the fluidic diffuser chamber, the flow of the fluid is exhausted through channels angling off at a predetermined angle from the center line of the normal flow of the fluid through the venturi. The predetermined angle, along with size of the fluidic diffuser chamber determines the frequency at which the diffuser system will self resonate. Fish hooks are attached to the lure having the self resonating system for catching the fish.
