Description

The present invention relates to a mouthpiece for a musical instrument, and is not particularly limited, but relates to a mouthpiece for use in a vertical flute.

A variety of wind instruments are available, including woodwinds offered in a variety of shapes and structures. Among them, the vertical flute may include duct flutes, which may include, for example, common recorders, and rim blow flutes, which may include Asian flutes such as shakuhachi in Japan, Dong Xiao in China, and Danso in South Korea. It can be classified into types including (also called edge blow flute or end blow flute). Playing Asian whistles is known to be difficult, and the average performer, especially a novice or inexperienced performer, sometimes sounds good, even after weeks or months of practice. Can often be difficult to issue. The difficulty of playing Asian flutes, such as the Japanese shakuhachi, can be attributed to the unique structure of the instrument. Specifically, it is equivalent to a commonly known Western Asian whistle such as a recorder, which has a ventilation path (also called a fipple) for directing air flow to the internal cutting edge provided inside the whistle body. In contrast to the object, the upper end of the shakuhachi has a wide opening (as in Figure 1), and its proper sound production is such that the performer has an upper opening or an inner peripheral edge or rim of the upper end. This can only be achieved if the air flow can be accurately blown out at an appropriate blow-out angle. In addition, the need for the performer to position the jaws to cover or partially cover the upper opening alters the effect of sound production. This special technique of changing the pitch of the generated sound, also known as the "pitch bend effect," is a unique and characteristic musical effect of Asian flutes, structurally realized in Western flutes such as recorders. It is impossible to do.

Many mouthpieces in the prior art have been developed to allow easier sound production with Asian whistles. However, most of the prior art is a "recorder" type mouthpiece with a limited vent for directing airflow to the outlet edge of the upper opening, as shown in the examples of FIGS. 2 and 3. Or just provide a mouthpiece. However, these types of mouthpieces are structurally incapable of exerting a "pitch bend" effect by the user, which is not desirable.

[Purpose of the device]
An object of the present invention is to provide a mouthpiece for a musical instrument such as a vertical flute.

Another object of the present invention is to, to some extent, alleviate or eliminate, or at least a useful alternative, one or more problems associated with a known vertical flute or mouthpiece for a vertical flute.

The above object is fulfilled by a combination of features of the main claim, the dependent claim discloses a more advantageous embodiment of the present invention.

Those skilled in the art will derive other objectives of the invention from the following description. Therefore, the purpose of the preamble is not exhaustive and merely serves to explain some of the many purposes of the present invention.

In the first main aspect, the present invention provides a mouthpiece for a musical instrument having a tubular structure. The mouthpiece features a body that defines a central hole with an open end, which is a lip engagement acceptable by the user's lips with a connection for detachably connecting the mouthpiece to the top of the instrument. The lip engaging portion, including the portion, defines an air passage separate from the central hole and is adapted to direct the airflow from the user's lips to a portion of the inner peripheral edge at the upper end of the tubular structure of the instrument. Be made to.

The following description is not limited to the combination of features required to carry out the present invention, but is a preferred embodiment as merely an example.

References herein to "one embodied" or "an embodied" are the specific features, structures, or properties described in connection with such embodiments. Means to be included in at least one embodiment of. The appearance of the phrase "in one embodied" in various parts of the specification does not necessarily refer to the same embodiment and is mutually exclusive with other embodiments. Nor is it a separate or alternative embodiment. In addition, various features that may be exhibited by some embodiments and not by others are described. Similarly, various requirements that may be requirements of some embodiments but not of others are described.

The present invention relates to a mouthpiece for a musical instrument, although not exclusively, such as a rim blow flute or an edge blow flute, and more specifically, such as a Japanese shakuhachi, a Chinese dong Xiao, and a Korean danso. Mouthpieces for vertical flutes such as Asian flutes are, but are not limited to. As mentioned above, it is a characteristic structural feature of most traditional Asian whistles that the top 10 or head 10 comprises a relatively wide and substantially circular top opening 12. It is configured to extend along the length of the whistle body as it forms the hollow cylindrical hole 13 of the tubular whistle structure, as shown in FIG. To generate sound, the performer needs to accurately blow airflow toward the inner rim or edge 14 (also referred to as the blowout edge 14) at the top opening 12. The performer may further arrange the jaws to partially close or cover the upper opening 12 to vary the blowing angle and adjust the pitch of the produced sound. In the conventional structure, the blowout edge 14 of the Asian whistle can be either with or without a notch. The top 10 of a traditional shakuhachi with a round top opening 12 and a notched blowout edge 14 is shown in FIG. 1 as an example.

As mentioned above, the wide circular opening 12 at the top 10 is known to be an original structural feature of Asian flutes, in particular the top opening 12 is made by the performer. It makes it possible to perform a sound "pitch bend", which is a characteristic musical effect that can only be achieved with the Asian vertical flute of the rim blow. A sound "pitch bend" is performed by the performer by adjusting the blowout angle and partially closing or covering the top opening 12 through relative movement between the performer's jaw and the top opening 12. Allows for substantial control and pitch changes. Also, as mentioned above, due to these unique structural features, traditional Asian flutes are known to be much more difficult to learn and play than Western vertical flutes such as recorders.

Therefore, the present invention is designed to provide a mouthpiece that helps to provide easier sound generation, more specifically with the characteristic musical effects of Asian whistles such as the shakuhachi. It allows for some pitch bend of the generated sound. In the context of the present specification, references to "rimblow flute", "Asian flute", "vertical flute", "flute" and "shakuhachi" are not limited, but as previously shown, in Japan. Used interchangeably for common types of rim blow flutes, vertical flutes, including various Asian flutes such as shakuhachi, Chinese dong Xiao, Korean danso, or other vertical flutes with similar structure. obtain. It should also be understood that in certain embodiments or illustrations, references to certain types of rim blow flutes, such as the shakuhachi, are not considered limiting. Instead, one of ordinary skill in the art will appreciate that it is readily applicable to musical instruments with similar structure or functionality.

With reference to FIGS. 4 to 7, a first embodiment of the mouthpiece 20 of the present invention is shown. The mouthpiece 20 comprises a body 22 defining a central hole 24 having two open ends, ie, an upper open end 26 and a lower open end 28, the upper open end 26, the lower open end 28 and the center. The holes 24 are spatially connected in forming a single continuous air passage. In one embodiment, the central hole 24 is preferably substantially matched in shape and dimensions to the upper end opening 12 of the shakuhachi tubular whistle body so that the mouthpiece 20 is shakuhachi. When attached or provided to the top 10, the central hole 24 can be joined in line with the cylindrical hole 13 of the whistle body to form a smooth, continuous air passage or conduit.

Preferably, the body 22 of the mouthpiece 20 may further comprise a connecting portion 30 for detachably connecting or attaching the mouthpiece 20 to the upper end 10 of the shakuhachi. For example, in embodiments as shown in FIGS. 4-7, as shown in FIG. 7, the connection 30 engages or accepts at least a portion of the outer peripheral wall 15 of the upper end 10 of the whistle body. Is configured to removably connect the upper end 10 of the shakuhachi. In an alternative arrangement, the connection 30 can be configured to be acceptable by the inner peripheral wall 16 at the top 10 of the shakuhachi, the embodiment of which will be described in more detail later. More preferably, the connection 30 is adapted to connect the top 10 of the shakuhachi by frictional engagement, and thus the connection 30 is preferably between the connection 30 and the top 10 of the shakuhachi. Due to the close fit, the shape and dimensions are substantially identical to the outer or inner circumference of the peripheral wall 15 or 16.

After the mouthpiece body 22 is attached to the upper end 10 of the shakuhachi via the connection portion 30, the open ends 26, 28 of the central hole 24 are along the cylindrical hole 13 of the mouthpiece body 22 and the whistle body. It is important to note that it allows for space / air communication with open air. More specifically, the opening end 26 of the mouthpiece 20, that is, the upper opening 12 of the shakuhachi, remains open to the air, and the size of the opening 26 at the opening end is the size of the mouthpiece 20. Is substantially similar in size to the open end 12 and the cylindrical hole 13 of the shakuhachi after it is attached to the upper end 10 of the shakuhachi. Therefore, the characteristic pitch bend of the shakuhachi can be performed by the user's operation of the upper open end portion 26 of the mouthpiece 20. It is a prior art as shown in FIGS. 2 and 3, where it is structurally impossible to provide a pitch bend effect due to the top being essentially closed except for narrow duct passages or fillles. In contrast to most removable mouthpieces.

Preferably, the body 22 of the mouthpiece 20 may further comprise a lip engaging portion 40 that is acceptable by the user's lips during use. The lip engaging portion 40 defines an air passage 42 so that sound can be easily generated by directing an air flow from the user's lips to the outlet edge portion 14 of the upper end 10 of the whistle body at a preferable angle. It is composed. Specifically, the air passage 42 is provided separately from the central hole 24 so that a gap distance is maintained between the outlet 44 of the air passage 42 and the outlet edge portion 14 of the upper end 10 of the shakuhachi. Preferably, it is separated from the upper end 10 of the whistle body. This interval has been found to be important for sound production. If the distance is too short, the volume produced will be low and the sound quality will be poor, and if the distance is too long, the volume will be high but the sound quality will be more dispersed. In one embodiment, the outlet 44 of the lip engaging portion 40 is preferably separated from the outlet edge portion 14 of the shakuhachi by a distance of about 2 mm to about 10 mm in order to enable the generation of acceptable sound quality. More preferably, they are separated by a distance of about 5 mm to about 6 mm in order to generate appropriate sound quality. In the embodiment shown in the figure, the lip engagement portion 40 may be configured to define an air passage 42 having a bow-shaped or crescent-shaped cross-sectional area (see FIG. 6). However, it is understood that the air passage 42 is not limited to this particular embodiment, but also includes variations in the shape and structure of the air passage, such as shapes such as semi-circular, rectangular or polygonal.

Alternatively, as long as the blowout edge portion 54 of the mouthpiece is provided substantially across the flow direction of the air flow, the blowout edge portion 54 of the mouthpiece may be a linear horizontal edge portion, a linear inclined edge portion, or the like. Can be configured to include. In a further embodiment, the outlet edge portion 54 of the mouthpiece is preferably tapered, with an acute-angled edge facing the air flow, and more preferably an acute angle of about 10 to about 50 degrees. Thus, the mouthpiece outlet 54 optionally functions to replace or collaborate with the shakuhachi outlet 14 to provide an airflow cutting edge for sound generation. do. Next, the air flow that hits the cutting edge is divided, and one of the divided side currents enters the cylindrical hole 13 to resonate the columns of air in it to generate sound.

In one embodiment, as shown in FIG. 6, the central hole 24 may define the maximum hole diameter Dmax and the lip engaging portion 40 may define the maximum width Wmax of the air passage 42. The maximum width Wmax and maximum hole diameter Dmax of the air passage 42 are preferably provided in a ratio of about 1: 1.1 to about 1: 2.5. For example, in one particular embodiment, the maximum hole diameter Dmax of the mouthpiece body 22 can be from about 10 mm to about 60 mm, and the maximum width Wmax of the air passage 42 is from about 5 mm to about 20 mm, more preferably. It can be about 8 mm to about 14 mm. As shown in FIG. 6, the lip engaging portion 40 can further define the maximum height Hmax to the maximum width Wmax of the air passage 42, and the ratio of the maximum height Hmax to the maximum width Wmax is about 1: 1. A ratio of 3 to about 1:20 is desirable.

In a further embodiment, for a standard size shakuhachi with a hole diameter of about 20 mm, a suitable mouthpiece 20 would have a maximum hole diameter Dmax of about 18 mm to about 20 mm, a maximum width Wmax of about 7 mm to about 13 mm, and more. Preferably, it may be provided at about 9.5 mm and a maximum height Hmax of about 1 mm to about 3 mm, more preferably about 1.8 mm. It is understood that changes in the dimensions of various parts of the mouthpiece can affect the quality of the sound produced by the mouthpiece and the instrument. For example, an air passage 42 having a rectangular cross section measuring about 13 mm (width) x about 3 mm (height) can produce poor quality sound.

Referring to FIGS. 8 to 11, in the second embodiment of the mouthpiece 20 of the present invention, when the mouthpiece 20 is arranged or attached to the shakuhachi, the connection portion 30 is the inner peripheral wall 16 of the upper end 10 of the shakuhachi.
