Abstract
An animal call includes a mouthpiece, a barrel, and a reed. The mouthpiece defines an air channel therein and has a reed bed proximate the air channel. The barrel is coupled to the mouthpiece and has an internal chamber that is fluidically coupled to the air channel of the mouthpiece. A surface comprising the air channel varies in order to maintain a substantially constant cross-sectional area magnitude along a length of the channel. The reed is disposed adjacent the air channel and proximate the reed bed.
Claims10
An animal call comprising:
- a mouthpiece defining an air channel therein and having a reed bed proximate the air channel, the air channel having a bottom surface that is curved along a length of the air channel, wherein the reed bed has a curvature in a same direction as the curvature of the surface of the air channel;
- a barrel coupled to the mouthpiece and having an internal chamber that is fluidically coupled to the air channel of the mouthpiece;
- wherein the surface of the air channel varies in order to maintain a constant cross-sectional area along the length of the air channel;
- and
- a reed disposed adjacent the air channel and proximate the reed bed.

An animal call comprising:
- a mouthpiece defining an air channel therein and having a reed bed proximate the air channel, the air channel having at least a bottom surface that is curved along a length of the air channel, the reed bed having a curvature in a same direction as the curvature of the bottom surface of the air channel, wherein the mouthpiece includes a bottom surface having a curvature along a length of the bottom surface of the mouthpiece that is in the same direction as the curvature of the reed bed;
- a reed disposed adjacent the air channel and proximate the bottom surface of the air channel;
- a barrel having a top surface spaced apart from a bottom surface to define an internal chamber that is fluidically coupled to the air channel of the mouthpiece, wherein the bottom surface of the barrel is planar and at least a portion of the top surface of the barrel has a curvature;
- and
- wherein the bottom surface of the air channel is curved such that a constant cross-sectional area magnitude is maintained along the length of the air channel.
