INHALATION-BASED REEDLESS WIDGEON DUCK CALL

Abstract

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.

DETAILED DESCRIPTION

[0039] FIG. 1 is a side view of a user holding the duck call device 100 and pressing his lips and mouth against a proximal opening 101 of the device 100 before inhaling to cause the duck call device to emit sounds closely resembling Widgeon duck sounds.

[0040] To use the device 100, with the lanyard loop 104 facing away from the user, the user places his lips and mouth over the proximal opening 101 of the device, as shown in FIG. 1. The better the seal with the lips and mouth, the less air is needed to make the device work. The user Inhales with one short breath, one long breath, one short breath, to make a series of sounds like: ho, hoo, ho. The user of the device 100 will soon see ducks appear in response to the sounds.

[0041] FIG. 2 is a perspective view of the duck call device 100 of FIG. 1, looking into the proximal opening 101 of the device 100, showing the inhalation exit hole 105 and the lanyard connector loop 104. When the user inhales into the device 100, air is sucked through the device, including passing through the inhalation exit hole 105. Device 100 includes a barrel 104, defined by a curved surface 107. The curved surface extends to proximal edge 111 to define a proximal open end 101 of barrel 104, and extends to a distal edge 109 to define a distal open end 108 of barrel 104.

[0042] FIG. 3 is an exploded perspective view of one embodiment of the device 100, showing an inner barrel 300. The inner barrel 300 includes a curved surface 332 extending between proximal edge 312 and distal circumferential tab 320b, defining proximal opening 301 and distal opening 330, and has a proximal convex dome 302 disposed therein that extends toward proximal opening 301. In an embodiment, the proximal convex dome 302 is integral with an inner surface of the inner barrel 300. The proximal dome 302 includes an inhalation exit hole 305 concentrically disposed therein.

[0043] FIG. 3 also shows an outer barrel 304. The outer barrel 304 includes a curved surface 307 extending between proximal edge 311 and distal edge 309, defining proximal opening 315 and distal opening 308, and has a distal convex dome 310 disposed therein that extends toward distal opening 308. In an embodiment, the distal convex dome 310 is integral with an inner surface of the inner barrel 300. The distal dome 310 includes an inhalation entry hole 306 concentrically disposed therein. The outer barrel 304 also includes the lanyard connector loop 104 of FIG. 2.

[0044] To assemble, the inner barrel 300 at the distal opening 330 is inserted into the proximal opening 315 of outer barrel 304, bringing the proximal convex dome 302 into a sealed back-to-back relationship with the distal convex dome 310, thereby forming a resonant chamber therebetween, that is sealed circumferentially within the outer barrel 304. When air is drawn into the device by the user inhaling, air rushes through the inhalation entry hole 306, and then exits through the inhalation exit hole 305, causing air flow instability within the resonant chamber, resulting in resonant vibrations that resemble the sound of a widgeon duck.

[0045] The inner barrel 300 and the outer barrel 304, and their respective proximal and distal convex domes 302 and 310, are made from IUPILON S-300UR (a type of Polycarbonate). Materials with similar Young's Modulus (density and stiffness) can also work. This includes many commodity plastics, such as Polycarbonate, ABS, Nylon, Polystyrene, Polyethylene, and Polypropylene.

[0046] FIG. 4 is a cutaway perspective view showing the proximal convex dome 302 of the inner barrel 300 and the distal convex dome 310 of the outer barrel 304, together forming a resonant chamber 502. FIG. 4 also shows the outer barrel 304 including the inhalation entry hole 306 and distal opening 308. The inhalation entry hole 306 is the round hole in the center of the distal convex dome 310. The outer barrel 304 also includes the lanyard connector loop 104.

[0047] FIG. 5 is a cutaway side view showing how the proximal convex dome 302 of the inner barrel 300 joins in a back-to-back relationship with the distal convex dome 310 of the outer barrel 304 to form a seam 500 circumferentially surrounding the resonant chamber 502 of FIG. 4.

[0048] FIG. 6 is a close up cutaway side view of the seam 500 of FIG. 5, showing the interlocking 600 circumferential tabs 320a, 320b of the inner barrel 300 and the outer barrel 304, respectively.

[0049] FIG. 7A is a cutaway top view showing exemplary dimensions of a barrel 700 of an alternative embodiment, the barrel 700 having a convex dome 702 extending towards the proximal open end 701, with an inhalation exit hole 705 disposed concentrically therethrough. The barrel 700 also has a distal open end 708, and a circumferential ledge 720 for sealing with a distal convex dome 710 (shown separately in FIGS. 8A-D). When included within the barrel 700, the distal convex dome 710 is oriented in within barrel 700 so that it extends towards the distal open end 708 of the barrel 700 while in a back-to-back arrangement with proximal convex dome 702, with the dial convex dome 700 to form a resonant chamber (not shown), such as the resonant chamber 502 as illustrated in FIG. 5.

[0050] In some embodiments, the proximal and distal convex domes are integral with an inner surface of the barrel, including at the circumferential ledge, the location at which the two domes are integrally and sealably coupled to one another circumferentially to form a seam.

[0051] FIG. 7B is a side view of the barrel 700 of the alternate embodiment of FIG. 7A, including the lanyard connector loop 706 and its exemplary dimensions. In an embodiment, the two convex domes are identical in dimension as illustrated.

[0052] FIG. 7C is a rear view of the barrel 700 looking into the distal open end 708 of barrel 700 without the presence of distal convex dome 710 of the alternate embodiment of FIG. 7A. FIG. 7A shows the inhalation exit hole 705 concentrically located in the proximal convex dome 702, and the lanyard connector loop 704. FIG. 8A is a perspective view of distal convex dome 710, which in this embodiment is typically formed integrally in back-to-back cooperation with the proximal convex dome 702 within the barrel 700, thereby forming the resonant chamber (such as resonant chamber 502 of FIG. 5) when the concave dome 710 is formed with the open distal end 708 of the barrel 700, thereby being integrally secured in a circumferentially sealed relationship with the circumferential ledge 710. As illustrated, the distal convex dome 710 has an inhalation entry hole 706 concentrically disposed therethrough.

[0053] FIG. 8B is a side view of the concave dome 710 having the inhalation entry hole 706. If FIG. 8C is a cut-away side view of the concave dome 710 having the inhalation entry hole 706, showing exemplary dimensions.

[0054] FIG. 8D is a rear view of the concave dome 710, showing an exemplary dimension of the inhalation entry hole 706.

[0055] While a widgeon duck call has been described and illustrated in detail, it is to be understood that numerous modifications can be made to the embodiments of the present invention without departing from the spirit and scope of the invention as claimed.
