Harmonica-style goose call

Abstract

A harmonica-style goose call is described. A user assumes a blow position and by blowing through a blow space onto a diaphragm which vibrates and emits a tone. The blow space is made from interior profiles of varying depth on engaged housings. This permits the user to alter the pitch of the tone by selectively altering the blow position. In this way, the user can imitate the sound of a goose by altering the blowing three and the blow position.

DETAILED DESCRIPTION

(5) A harmonica-style goose call generally identified by reference numeral 10, will now be described with reference to FIG. 1 through 3.

(6) Structure and Relationship of Parts:

(7) Referring to FIG. 2, the main components of goose call 10 are an elongated first housing 12, an elongated second housing 14, a flexible diaphragm 16 and wire binders 17. Referring to FIG. 3, first housing 12 has a first end 18, a second end 20, an exterior surface 22 and an interior surface 24. Interior surface 24 has a first supporting and clamping member 26 at first end 18, a second supporting and clamping member 28 at second end 20, and a first profile of varying depth, generally indicated by reference numeral 30, on that portion of interior surface 24 between first supporting and clamping member 26 and second supporting and clamping member 28. Second housing 14 has a first end 32, a second end 34, an exterior surface 36 and an interior surface 38. Interior surface 38 has a first supporting and clamping member 40 at first end 32, a second supporting and clamping member 42 at second end 34, and a second profile of varying depth, generally indicated by reference numeral 44, on that portion of interior surface 38 between first supporting and clamping member 40 and second supporting and clamping member 42. Wire binders 17 extend around first housing 12 and second housing 14, holding the first end of the first housing 18 to the first end of the second housing 32, ensuring that clamping members 26 and 40 remain clamped together, as well as holding the second end of the first housing 20 to the second end of the second housing 34, ensuring that clamping members 28 and 42 remain clamped together.

(8) Referring to FIG. 1 and FIG. 3, first supporting and clamping member 26 and second supporting and clamping member 28 of first housing 12 engage first supporting and clamping member 40 and second supporting and clamping member 42 of second housing 14 with first profile 30 and second profile 44 collectively forming a blow space, generally indicated by reference numeral 46. A flexible diaphragm 16 is stretched between respective engaged first supporting and clamping members 26 and 40 and respective engaged second supporting and clamping members 28 and 42.

(9) Referring to FIG. 3, first profile 30 and second profile 44 are undulating profiles. In the embodiment illustrated, first profile 30 has a second undulation towards second profile 44 to form a centrally located narrowing 50 in blow space 46.

(10) Operation:

(11) Referring to FIG. 1, with harmonica-style goose call 10, as described above, a user assumes a blow position and by blowing through blow space 46 causes diaphragm 16 to vibrate and emit a tone. Referring to FIGS. 2 and 3, the varying depths of first profile 30 and second profile 44 permit the user to alter the pitch of the emitted tone by selectively altering the blow position. in this way, the user can imitate the sound of a goose by altering the blowing force and the blow position.

(12) Differences with Bays Call:

(13) An examination was conducted of the Bays call to determine other factors that may contribute to a less or greater degree to the strong tonal differences. It is not entirely clear exactly how significant each of these factors may be, but these factors are being disclosed to ensure that successful results are always achieved.

(14) Width dimensionIt was noted that goose call 10 is considerably narrower than the Bays call as measured from the blow space positioned at a front of the first housing and the second housing to a back. The Bays call was slightly larger than a standard harmonica. The goose call 10 is smaller than a standard harmonica, with a width dimension of the first housing and the second housing of less than 2 centimetres.

(15) Flexible diaphragm The Bays call and goose call 10 both use an elastic band as a flexible diaphragm. The Bays call has a narrow strip of elastic material that is considerably smaller in width than the width of the housing, covering less than 20%. The flexible diaphragm of goose call 10 is substantially the same width as the housings, covering over 90%.

(16) Embodiments:

(17) In one embodiment, the goose call 10 is primarily constructed from wood. The goose call 10 may also be made from a polymer plastic or other suitable materials. Further, the goose call 10 may vary in overall scale, being larger or smaller to accommodate different users and different goals, in the preferred embodiment, the flexible diaphragm 16 is an elastic band that is substantially the same width as the first housing 12 and the second housing 14. In other embodiments the flexible diaphragm 16 may be narrower and have a smaller width than the first housing 12 and the second housing 14. In the shown embodiment the flexible diaphragm extends the length of the first and second housings 12 and 14. In other embodiments the flexible diaphragm might be shorter than the length of the housings. Slight variations in the shape of the internal profiles 30 and 44, particularly in the steepness of the slopes, may be made to accommodate these different embodiments in order to achieve the goose call sound.

(18) In this patent document, the word comprising is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article a does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.

(19) The scope of the claims should not be limited by the preferred embodiments set forth in the examples, but should be given a broad purposive interpretation consistent with the description as a whole.
