INHALATION-BASED REEDLESS WIDGEON DUCK CALL

机译:基于吸气的无胸野鸭电话

摘要

A duck call device is disclosed for emitting sounds resembling Widgeon duck sounds. The device includes a barrel having an open proximal end configured to make airtight contact with the user's lips, and an open distal end. The device also includes an open resonant chamber sealed circumferentially within the barrel, the open resonant chamber formed by an open convex dome sealed circumferentially to an open concave dome, each dome having a similarly sized central hole in coaxial relationship with the barrel. The open resonant chamber is sized, shaped, and made from a material so as to easily produce a realistic sound of a widgeon duck when a user sucks air in through the barrel. The open resonant chamber is substantially symmetric in that the open convex dome is a mirror reflected version of the open concave dome. The barrel includes a loop for securing a lanyard. No reed is used.
