[0070] Further, in the following description of the present disclosure, components that are determined to unclearly make the spirit of the present disclosure unclear, for example, well-known technology including the related art may not be described in detail.

[0071] FIG. 3 is a view showing a first embodiment of a head joint having a blow hole and a reed part for a wind instrument according to the present disclosure.

[0072] A head joint 10 having a blow hole 11 and a reed part 13 for a wind instrument according to the present disclosure is formed in a tube shape with one closed end, in which the blow hole 11 and the reed part 13 are spaced apart from each other at predetermined distances from the closed end.

[0073] The center of the blow hole 11 and the center of the reed part 13 are positioned at the same distance from the closed end, and the blow hole 11 and the reed part 13 are positioned to be spaced apart from each other in the circumferential direction of the head joint 10.

[0074] A wind instrument including the head joint 10 has both the blow hole 11 and the reed part 13, so it is operated as a both side open-type wind instrument by blocking the reed part 13 when it is played through the blow hole 11, and it is operated as a one side open-type wind instrument by blocking the blow hole 11 when it is played through the reed part 13. Accordingly, the wind instrument generates low tones that are one octave lower than the musical range of both side open-type wind instruments that are played through the blow hole 11, whereby it is possible to implement a wind instrument having expanded low tones and generate a musical range expanded one octave from the existing musical range.

[0075] When a sound is generated by blowing into a blow hole of a transverse flute of which one end of the tube is closed and that has a blow hole, it operates as a both side open-type wind instrument, tones of which the fundamentals are half wavelengths of the tube length are generated.

[0076] When a reed is attached and it is played through a reed part instead of the blow hole, it operates as a one side open-type wind instrument, so tones of which the fundamentals are ¼ wavelengths of the tube length are generated.

[0077] As described above, both the blow hole 11 and the reed part 13 are formed, the reed part 13 is blocked when an instrument is played through the blow hole 11, and the blow hole 11 is blocked when the instrument is played through the reed part 13, whereby a fundamental and a partial of a both side open-type wind instrument are generated through the blow hole 11 and a fundamental of a one side open-type wind instrument that is one octave lower than the fundamental of a both side open-type wind instrument is implemented through the reed part 13. Accordingly, it is possible to implement a wind instrument having expanded low tones by implementing low tones that are one octave lower than instruments having only a blow hole in the related.

[0078] Further, tones slightly over three octaves are implemented from an instrument that having only finger holes without keys and implements only tones slight over two octaves, and when the head joint 10 to which the present disclosure is applied is connected and used instead of the head joint of a piccolo or a flute that implements tones over three octaves, tones are expanded one octave lower than fundamental tones, so a wind instrument that implements tones over four octaves is achieved.

[0079] Meanwhile, the reed part 13 is a free reed and it is preferable that the width of a fixing part that is fixed of the free reed is larger than the width of the opposite end.

[0080] When the length of the reed of the reed part 13 is 1 and the acoustic tube length of a wind instrument is L, 0.04≤l.sup.2/L<0.11 is satisfied.

[0081] FIG. 4A is a view showing a region for blocking a reed part with diagonal solid lines and FIG. 4B is a view showing a region for blocking a mouth with diagonal solid lines.

[0082] The blow hole 11 and the reed part 13 are spaced apart from each other in the circumferential direction of the head joint 10 so that a user can close the reed part 13 with the portion of the face between the lower lip and the jaw when playing through the blow hole 11 and a user can close the blow hole 11 with the portion between the upper lip and the nose when playing through the reed part 13.

[0083] FIG. 5A and FIG. 5B are views showing a second embodiment of a head joint for a wind instrument having a mouth part and a reed part according to the present disclosure, in which FIG. 5A shows the state in which a reed part is covered with a cover and FIG. 5B shows the state in which a mouth is covered with a cover.

[0084] The blow hole 11 and the reed part 13 may be spaced apart from each other in the longitudinal direction of the head joint 10.

[0085] In this case, a cover 15 that can longitudinally slide is disposed on the outer circumferential surface of the head joint 10. The cover 15 is configured to block the reed part 13 when playing through the blow hole 11 and to block the blow hole 11 when playing through the reed part 13.

[0086] Further, the cover may be provided to be able to slide in the circumferential direction of the head joint.

[0087] The technique of providing the cover 15 to be slidable on the outer circumferential surface of the head joint 10 is well known in the art, so it is not described in detail.

[0088] For example, this configuration may be implemented by forming a sliding protrusion and a sliding groove.

[0089] A through-hole 15a is formed at the cover 15, and the blow hole 11 or the reed part 13 is opened through the through-hole 15a.

[0090] Further, one or more protrusions 15b are formed at the cover 15, and it is preferable that protrusions are formed in a pair at both sides of the through-hole 15a.

[0091] A user can open the blow hole 11 or the reed part 13 to the outside by sliding the cover 15 with his/her face in contact with the protrusion 15b such that the through-hole 15a is positioned over the blow hole 11 or the reed part 13.

[0092] FIG. 6 is a view showing a third embodiment of a head joint for a wind instrument having a mouth part and a reed part according to the present disclosure.

[0093] The reed part 13 is a free reed and a protector 17 formed in an elliptical ring shape is installed on the free reed at the reed part 13 to protect the free reed and make playing easy.

[0094] In this case, it is preferable that a hole of the ring-shaped protector 17 is positioned to communicate with the reed part 13.

[0095] A lower portion (an inner edge line of the bottom 17b and an outer edge line of the bottom 17c) of the hole of the protector 17 that comes in contact with the reed part 13 is formed larger than the free reed and the upper portion 17a is formed smaller than the free reed.

[0096] A hole larger or smaller than the length or width of a free reed is formed to be fitted to the size of the lips of a user by installing the protector 17 and adjusting the sizes of the upper and lower holes of the protector 17, whereby it is possible to easily play through the reed part 13 and easily block the reed part 13 when playing with the blow hole 11.

[0097] Meanwhile, when the head joint 10 described above is manufactured to the tube thickness of a flute or a piccolo that are existing wind instruments and then connected to the wind instruments, it is possible to implement expanded tones that are one octave lower than the first octave tones in an existing musical range.

[0098] FIG. 7 is a view showing a wind instrument including a head joint for a wind instrument having a blow hole and a reed part according to the present disclosure.

[0099] A wind instrument 1 according to the present disclosure is characterized by including the head joint 10 having a blow hole 11 and a reed part 13 for a wind instrument described above.

[0100] A both side open-type wind instrument was manufactured such that the tube length L was 31.1 cm and the tube diameter D was about 18 cm, and in this case, a musical range that could be easily made by playing the instrument through the blow hole was C5 (523 Hz)˜E7(2637 Hz), which corresponds to two octaves and two tones, and C4 (262 Hz)˜B4(494 Hz) was possible when playing through the reed part.

[0101] That is, an instrument that implements two octaves and two tones within from C5 to E7 when there is no reed part became an instrument that implements three octaves and two tones from C4 to E7.

[0102] That is, the musical range of a soprano flute of which the acoustic tube length is about 60 cm could by implemented as a wind instrument of which the acoustic tube length is about 30 cm.

[0103] In this case, the fundamental frequency of a reed is also important, and a free reed having a fundamental frequency higher than the frequency of the highest tone that is generated when a wind instrument is played through a reed part was used, the musical range of the wind instrument was generated well.

[0104] That is, when a free reed that generates a tone over C5 (523 Hz) as a fundamental frequency was formed and attached, high tones were easily generated from C4 (263 Hz) at the tube length of a sample.

[0105] A free reed is a reed that vibrates with a side fixed and the resonance frequency thereof is expressed as the following equation.

[00003]$f_n=\frac{\pi c\kappa }{8L^2}\left(1{\text{.194}}^2,{2.988}^2,5^2,7^2,.Math.\right)$

[0106] κ is a number corresponding to a radius of gyration when a reed bends, the number in the parentheses are constants that are multiplied for a fundamental, a second harmonic, a third harmonic, . . . .

[0107] That is, the resonance frequency is inversely proportion to a square of the length of a reed.

[0108] The reed length of the sample was about 14 mm.

[0109] A head joint having a mouth part and a reed part for a wind instrument according to the present disclosure and a wind instrument including the head joint were described by exemplifying a wind instrument such as a transverse flute, but can be applied to wind instruments such as a vertical flute too.

[0110] Various preferred embodiments of the present disclosure were described above through some examples, but the various embodiments described in “Best Mode for the Invention” are only examples and it would be clearly understood by those skilled in the art the present disclosure may be changed in various ways or equivalently implemented from the above description.

[0111] Further, it should be noted that since the present disclosure may be implemented in other various ways, the present disclosure is not limited to the above description, the above description is provided to completely explain the present disclosure and provided only to completely inform those skilled in the art of the range of the present disclosure, and the present disclosure is defined by only claims.
