Abstract
The invention discloses diaphragms for use in air horns or similar noise-producing devices. The diaphragms may have concave or convex non-linear shapes, wherein protrusions are included in the body of the rigid or semi-rigid diaphragm. The diaphragms made be made of any relevant materials and keep their non-flat shapes during and without application of compressed gas.
Claims19
A diaphragm for use in an air horn, wherein said diaphragm has a concave or convex profile or part of it substantially in the shape of a parabola or a plurality of superimposed or adjacent parabolas.
A diaphragm for use in an air horn, wherein said diaphragm has a rigid or semi-rigid non-flat resting surface shape.
A device for underwater communication, including the following:
- a source of compressed gas;
- an air horn, wherein the diaphragm used in said air horn has a rigid or semi-rigid non-flat resting surface shape;
- a hose connecting said source of compressed gas to said air horn;
- and,
- an activation element for allowing gas from said source to pass through said air horn, wherein said gas causes said diaphragm to vibrate before said gas egresses said air horn.
