A whistle is structured for promoting hygienic use of the whistle and for maximizing inlet air pressure to generate sound from the whistle. The whistle includes an air inlet having a channelizer for dividing and channeling air flow received from the air inlet through at least two different channels. A sound-generating chamber is in corresponding fluid communication with each of the channels, and an air exhaust is in fluid communication with the sound-generating chamber. The air exhaust is structured and located on the whistle body for generating a sound, and is positioned and structured at a location suitable for directing air flow away from the air exhaust in a generally downwardly and/or opposing direction with respect to a generally horizontal air flow direction at the air inlet.

A knife with a handle and a blade, associated with means adapted to emit sound using an air flow, the said means being incorporated inside the body of the said handle, and being of the whistle type, and comprising a recess connected to a mouthpiece located upstream, through which the said flow of air is introduced, and connected to an exit window located downstream. An air compression chamber located downstream from the mouthpiece, opens through a hole into an expansion chamber (or pressure relief chamber) which is itself connected to the said exit window. The compression chamber is such that its section along a plane orthogonal to the air flow reduces, preferably in a linear manner, in the direction of the expansion chamber. The exit window has a bevelled edge on the side opposite the compression chamber. The compression chamber opens onto two parallel expansion chambers having different lengths.

The present invention relates to a whistle and mouthpiece for a whistle and method of manufacturing that provides a flavored composition in the whistle mouthpiece material that the wearer can taste to make the use of the whistle more bearable over the course of its long use. A flavorant is infused within the thermoplastic material, which is dissolved to release flavor and allow the user to enjoy for a prolonged period of time. The method of manufacturing involves infusing flavorant within the thermoplastic material of the whistle mouthpiece.

A universal game call includes a barrel having an exhaust end and an intake end and a first inner diameter and the exhaust end and a second inner diameter at the intake end. The barrel is configured to connect to a plurality of calls and accessory pieces. The first call includes an insert end and a reed positioned within the insert end and configured to extend into the barrel when the call is joined to the exhaust end of the barrel. The second call includes an insert end and a mouthpiece end and a reed positioned within the mouthpiece end and extending away from the second call, exterior to the call and barrel. When the first call is connected to the barrel, a first animal sound is produced by forcing air through the barrel from its intake end. When the second call is connected to the barrel, the second animal sound is produced by forcing air through the reed.
