Abstract: A duck call for reproducing the sounds made by certain whistling ducks without having to flutter the tongue comprising a main body, a mouthpiece frictionally connected to the main body and a tubular roller disposed in a central sound chamber located in the main body of the whistle. Air blown by the user enters the open end of the mouthpiece and passes through an air vent on the mouthpiece into the central sound chamber. A slot formed at the interface of the end of the mouthpiece and an air vent in the main body creates a whistle sound that is directed into the sound chamber to rotate the tubular roller to produce the vibrato effect necessary to emulate the whistling-type ducks. A pair of side members having air chambers therein can be connected to the main body to create a larger resonant chamber in which the roller rotates. Apertures at the closed end of the side members can be open or closed by the user's fingers to selectively produce sounds that mimic other whistling-type ducks.

Abstract: A whistle (1) has: a mouthpiece which includes an air inlet (4); a first and a second resonance chambers (5a, 5b) to which air is injected through the air inlet via a first and a second air passages (6a, 6b); a first and a second sound outlets (7a, 7b) in the form of openings formed between the air passages and the resonance chambers; and a first and a second air flow converters (9a, 9b) for varying the flow of air between the air passages and the sound outlets. The air flow converters (9a, 9b) are each part of the sound outlets, and have walls (10a, 10b) which are perpendicular to the air passages (6a, 6b).

Abstract: A cord is formed into a loop with a metal clip, and is knotted about a rigid ear which protrudes from the body of a conventional whistle. A plastic tube is slipped over the knotted lanyard at the whistle ear and heat-shrunk in place, to cause the whistle to protrude from the lanyard on a generally rigid stem. When the lanyard is slipped onto the glove of the wearer, the protruding stem causes the whistle to extend outwardly from the glove and hence presents the mouthpiece of the whistle for ready grasping by the wearer's lips for rapid actuation of the whistle. Alternatively, the whistle is engaged to a hook-and-loop fastener flexible strap by a rigid clip, which extends through a fold in the strap. The connection between the clip and the fastener limits side to side twisting of the whistle, allowing ready blowing by the wearer.
