DETAILED DESCRIPTION OF THE EMBODIMENTS
The present invention discloses a wind instrument made of a suitable foodstuff, and which is configured such that a user thereof blowing into an air entry of the wind instrument causes the vibration of a column of air in the instrument's cavity, thereby generating sound.
In accordance with an embodiment of the present invention, the foodstuff comprises flour. Accordingly, the wind instrument may be made of the same ingredients as pasta (i.e., at least dried dough). Consequently, a plurality of edible wind instruments may for example be offered in packages for sale to potential buyers, whereby a buyer of such a package may for example use some of the wind instruments for amusement of, e.g., his children by generating a sound therewith, and later process (e.g. cook) the same wind instruments to render the foodstuff of which the wind instruments are made of edible.
Where applicable, although state diagrams, flow diagrams or both may be used to describe embodiments, the invention is not limited to those diagrams or to the corresponding descriptions. For example, flow need not move through each illustrated box or state, or in exactly the same order as illustrated and described.
Referring now to FIG. 1A, FIG. 1B, FIG. 1C and FIG. 1D, a wind instrument 101 according to an embodiment of the invention comprises an envelope defining a tubular body 131 having a resonator cavity 110.
It should be noted that terms “tubular body”, “tubular envelope”, and grammatical variations thereof as used herein, refers to any envelope defining a hollow cavity, wherein the cross-section of the envelope may define any kind of closed curve.
Wind instrument 101 has a first end 120 and second end 125, wherein first end 120 and second end 125 may selectably constitute an air entry 121 and a sealable opening of resonator cavity 110. Additionally, wind instrument 101 further includes a labium opening 115, which is an opening of resonator cavity 110 to the air ambient and which is disposed across a middle portion of tubular body 131. If one end of resonator cavity 110 is sealed and a user of wind instrument 101 blows via the other end into resonator cavity 110, the oscillation of air in resonator cavity 110 may be effected, which may result in the generation of sound. Each portion of resonator cavity 110 on either side of labium opening 115 may vary and/or differ in length and/or shape, thereby influencing the tone and/or tone pitch that may be generated by means of resonator cavity 110.
It should further be noted that the termination of resonator cavity 110 may be sealed by various means. For example, a tip (e.g. second end 125) of resonator cavity 110 may be sized such that it is sealable by a finger of a user blowing into wind instrument 101. Alternatively, the respective tip of resonator cavity 110 may, for example, be tapered to achieve sealing of the same tip of resonator cavity 110. Thusly configured, wind instrument 101 may in some embodiments of the invention constitute a whistle. It should be noted that if wind instrument 101 is made of dough or any other material that undergoes hardening, then such tapering may be performed prior to or after the hardening process.
Additional reference is now made to FIG. 2A, FIG. 2B, FIG. 2C, FIG. 2D, FIG. 2E, FIG. 3A, FIG. 3B, FIG. 3C, FIG. 3D, FIG. 3E, FIG. 3F, FIG. 3G, FIG. 3H, FIG. 3I, FIG. 3J, FIG. 4A, FIG. 4B, FIG. 4C, FIG. 4D, FIG. 4E, FIG. 4F, FIG. 4G, FIG. 4H, FIG. 4I, FIG. 4J, FIG. 4K, FIG. 4L, FIG. 4M, FIG. 4N, FIG. 5A, FIG. 5B, FIG. 5C, FIG. 5D, FIG. 6A, FIG. 6B and FIG. 6C, FIG. 7A, FIG. 7B and FIG. 7C which schematically illustrate further embodiments of wind instrument 101.
In some embodiments of the invention, air entry 121 of respective wind instruments 102, 103 104, 105, 106 and 107 may have different shapes. For example, air entry 121 may be cup-shaped or tapered.
Specifically referring now to FIG. 2A, FIG. 2B, FIG. 2C, FIG. 2D and FIG. 2E, wind instrument 102 has a second end 126 that is fixedly sealed. Such sealing may be achieved, for example, by exerting forces (F) against the envelope of wind instrument 102, to cause the reshaping of second end 125 into a sufficiently tapered form, and consequently result in a sealed second end 126 and a substantially flat or compressed portion 135.
Specifically referring now to FIG. 4A, FIG. 4B, FIG. 4C and FIG. 4D, wind instrument 105 has two open ends, and includes a compressed or bent portion 142 located substantially in the center of wind instrument 105. The cavity of wind instrument 105 is narrower at bent portion 142. A labium opening 115 is formed in the bent portion 142 of wind instrument 105.
Specifically referring now to FIG. 4E, FIG. 4F, FIG. 4G, FIG. 4H and FIG. 4I, wind instrument 106 has two open ends, and includes a compressed or bent portion 143 located in a middle portion of wind instrument 106, closer to one of the two ends (i.e., not in the center thereof). A labium opening 115 is formed in the bent portion 143 of wind instrument 106.
Specifically referring now to FIG. 4J, FIG. 4K, FIG. 4L, FIG. 4M and FIG. 4N, wind instrument 107 has one open end and one sealed end, and includes a compressed or bent portion 144 located in a middle portion of wind instrument 107, closer to the open end (i.e., not in the center thereof). A labium opening 115 is formed in the bent portion 144 of wind instrument 107.
Specifically referring now to FIG. 5A, FIG. 5B, FIG. 5C and FIG. 5D, wind instrument 108 further includes at least one fingerhole 130. Closing and opening at least partially one or more fingerholes 130 (e.g., with a finger) while blowing into air entry 121 changes the effective volume of the vibrating air column. Consequently, an alteration of the air's frequency of vibration in resonator cavity 110 is effected, which in turn changes the musical note and/or the note's pitch sounding from wind instrument 108.
With reference to FIG. 5B, both ends 125 and 126 of a wind instrument 102 may be open to the ambient. Moreover, labium 115 may be located off-centered with respect to the overall length of wind instrument 102. Thusly configured, each end 125 and 126 may selectably constitute an air inlet and be closeable by, e.g., a finger of the user, where the blowing of air into either one end 125 and 126, whilst closing the corresponding other end, results in different tones, due to the respective different volumes of resonator cavity in wind instrument 102 created by the off-centered location of labium 115.
It should be noted that wind instrument 101 and embodiments thereof may be made of edible material such as, for example, dried dough, in its hardened or rigid form. In some embodiments of the invention, wind instrument 101 may for example be made of dried dough and shaped to have the functionality that is respectively analogous to, e.g., a panpipe, a mouth harmonica, or any other typically wood and/or plastic-based wind instrument.
Specifically referring now to FIG. 6A, FIG. 6B and FIG. 6C, according to corresponding embodiments of the invention, the longitudinal section of tubular body 131 delineates at least one of the following shapes: straight, curved, helical, and S-shaped.
Specifically referring now to FIG. 7A, FIG. 7B and FIG. 7C, according to corresponding embodiments of the invention, the cross-section of tubular body 131 of wind instruments delineates at least one of the following shapes: elliptic, circular, rectangular, triangular and pentagonal.
Reference is now made to FIG. 8. As indicated by box 810, the method for manufacturing a wind instrument includes the procedure of shaping flour based foodstuff (e.g. a dried dough piece) to a tubular envelope defining a cavity. Referring back to FIG. 1A, flour based foodstuff, such as dried dough for the preparation of pasta, is formed into tubular body 131 defining resonator cavity 110.
As indicated by box 820, the method further includes the procedure of cutting the tubular envelope to form a first end and a second end, where the first end is an open end, enabling a user of the wind instrument to blow air thereinto to generate sound while the second end is being sealed. Referring back to FIG. 1A, tubular body 131 is cut to form a first end 120 and a second end 125, such that when a user blows into open end 120 while sealing the other end 125 (e.g., by pressing a finger to seal the end), it results in the generation of sound from tubular body 131.
As indicated by box 830, the method further includes the optional procedure of compressing a portion of the tubular envelope, for narrowing the diameter of the cavity at the portion. The compressing may be achieved by bending the tubular envelope. The compressing may also result in the formation of different shapes for the tubular envelope. Referring back to FIG. 4A, FIG. 4B, FIG. 4C, and FIG. 4D, wind instrument 105 is compressed at section 142, resulting in a narrowed resonator cavity 110 at section 142 of wind instrument 105.
As indicated by box 840, the method further includes the optional procedure of sealing the second end of the tubular envelope. The sealing process is performed prior to hardening the foodstuff (procedure 850), when the open end is deformable without causing breaking of the flour based foodstuff. Referring back to FIG. 2A, FIG. 2B, FIG. 2C, FIG. 2D, and FIG. 2E, second end of tubular body 131 is fixedly sealed, resulting in sealed end 126.
As indicated by box 850, the method further includes the procedure of hardening the flour based foodstuff. The hardening process may be performed by drying the foodstuff.
As indicated by box 860, the method further includes the procedure of cutting an opening constituting a labium on a portion of the tubular envelope. It is noted that procedure 860 may alternatively be performed prior to hardening the foodstuff (procedure 850). The labium is generally disposed in a middle portion of the tubular envelope. Referring back to FIG. 1A, FIG. 1B, FIG. 1C, and FIG. 1D, labium 115 is cut into a portion of tubular body 131. Referring back to FIG. 4A, FIG. 4B, and FIG. 4C, labium 115 may be formed in the compressed section 142 of tubular body 131.
While the invention has been described with respect to a limited number of embodiments, these should not be construed as limitations on the scope of the invention, but rather as exemplifications of some of the embodiments. Those skilled in the art will envision other possible variations, modifications, and programs that are also within the scope of the invention.
