Description

Flute family instrument headstock assembly

The present invention relates to a mouthpiece assembly, and in particular to a mouthpiece assembly for a flute family musical instrument.

The flute is the main high-pitched melody wind instrument in wind and chamber music. Its main structure is a cylindrical long tube with several sound holes and multiple keys that can cover or expose the sound holes. The flute itself is usually made of wood (such as ebony or coconut wood) or metal (such as nickel-silver alloy, silver alloy, gold alloy or platinum and gold). The timbre of a wooden flute is round, warm and delicate, while the timbre of a metal flute is clearer.

Please refer to the first to third figures, the first figure is a partial three-dimensional diagram of the mouthpiece assembly and the flute body assembly in the prior art after being decomposed, the second figure is an exploded diagram of the components of the mouthpiece assembly in the prior art, and the third figure is a cross-sectional view of the mouthpiece assembly along the A-A section in the first figure. As shown in the first to third figures, from a structural point of view, the flute in the prior art mainly includes a mouthpiece assembly PA1, a flute body assembly PA2 and a flute tail assembly (not shown), wherein the mouthpiece assembly PA1 mainly includes a mouthpiece tube PA11, a reverberation plate PA12, a cork PA13, a locking screw PA14, a clamping plate PA15, a mouthpiece nut PA16 and a connecting tube PA17.

The mouthpiece PA11 includes a body PA111 and a lip pad PA112. The body PA111 is a hollow tube structure, and has a first end opening PAOP1 and a second end opening PAOP2 at both ends. The lip pad PA112 is disposed on the outer peripheral wall of the body PA111, between the first end opening PAOP1 and the second end opening PAOP2, and has a blowing hole PABH.

The clamping plate PA15 is disposed near the first end opening PAOP1 of the body PA111 and is fixed in the body PA111. The resonant plate PA12 is located in the body PA111 near the lip pad PA112. The cork PA13 is disposed between the clamping plate PA15 and the resonant plate PA12. The locking screw PA14 extends from the resonant plate PA12, passes through the cork PA13 and the clamping plate PA15 in sequence, and is screwed and fixed to the mouthpiece nut PA16. The mouthpiece nut PA16 can be screwed or clamped to the first end opening PAOP1 to close the first end opening PAOP1 and be fixed to the mouthpiece tube PA11. In the above structure, the reverberation board PA12 and the cork PA13 act like a stopper.

Next, the main functions of the above-mentioned related structures are explained as follows: by adjusting the number of threads of the locking screw PA14 locking into the mouthpiece nut PA16, the position of the reverberation plate PA12 can be fine-tuned, that is, the distance between the mouthpiece plug and the second end opening PAOP2 can be adjusted to adjust the position of the reverberation node and the effective tube length; the reverberation plate PA12 and the clamping plate PA15 can be clamped and clamped with the cork PA13, so that the cork PA13 provides an elastic restoring force; and the elastic restoring force provided by the cork PA13 can push and fix the reverberation plate PA12 to prevent the reverberation plate PA12 from being skewed by airflow or sound wave vibration.

However, in the above structure of the prior art, there is a very serious and difficult to overcome problem. The problem is that the material of softwood PA13 itself is easy to shrink and deform, and the long-term compression by the reverberation board PA12 and the pressing board PA15 causes elastic fatigue, which further aggravates the shrinkage and deformation. Once the shrinkage and deformation reaches a certain degree, not only can it no longer provide sufficient elastic recovery force for the reverberation board PA12 to maintain a fixed reverberation node position and effective tube length, but it will also produce cracks and cause air leakage, thus causing serious pitch deviation problems.

In view of the fact that the method of fixing the reverberation board by tightening the cork in the prior art is prone to cause serious pitch deviation problems, the main purpose of the present invention is to develop a new structure to achieve the purpose of fixing the reverberation node position and maintaining the effective tube length, so as to solve the serious pitch deviation problem. Accordingly, a necessary technical means adopted by the present invention to solve the problems of the prior art is to provide a mouthpiece assembly of a flute family musical instrument, which is used to be assembled on a flute body assembly of a flute family musical instrument and includes a mouthpiece tube and a connecting tube.

The mouthpiece includes a body and a lip pad. The body is an integral component having a closed end and an open end, and is provided with an opening and an air flow vibration chamber. The opening is provided at the open end. The air flow vibration chamber extends from the opening toward the closed end and has a resonant concave surface adjacent to the closed end.

The lip pad is formed between the closed end and the open end, and protrudes from the main body in an integral manner. A blowing hole connected to the air flow vibration chamber is provided, so that a player's lips can approach to blow an inflow into the air flow vibration chamber, and the inflow vibrates and reverberates on the reverberating concave surface to generate a blowing sound wave. The connecting pipe is inserted and fixed at the open end, and extends out of the opening for assembly to the flute body assembly. The flute family musical instrument described above can be any one of a treble flute, an alto flute, a bass flute and a piccolo.

Based on the above necessary technical means, the following subsidiary technical means can be derived. Preferably, the resonant concave surface can be a hemispherical concave surface or an arc-shaped concave surface. The mouthpiece assembly can further include a mouthpiece crown, and the closed end of the body is further provided with a mouthpiece crown mounting groove, and the mouthpiece crown is mounted and fixed in the mouthpiece crown mounting groove. In addition, with respect to the material part of the mouthpiece assembly, preferably, the mouthpiece tube can be a wooden mouthpiece tube or a metal mouthpiece tube; and the connecting tube can be a metal connecting tube.

In summary, in the mouthpiece assembly of the flute family musical instrument provided by the present invention, the mouthpiece tube itself is an integrated component having a closed end and an open end. Therefore, after an air flow vibration chamber is opened from the open end toward the closed end, the reverberation concave curved surface adjacent to the closed end in the air flow vibration chamber can always maintain a consistent distance from the open end, so as to ensure that the reverberation node position and the effective tube length can always be maintained consistent, thereby achieving the effect of maintaining a fixed pitch after long-term use.

Since the mouthpiece assembly of the flute family musical instrument provided by the present invention can be widely used in various flute family musical instruments, it will not be described one by one here. Only a preferred embodiment is listed to be specifically explained, and this embodiment is only used to conveniently and clearly assist in explaining the purpose and effect of the embodiment of the present invention.

Please refer to the fourth to sixth figures, the fourth figure is a partial stereogram showing the mouthpiece assembly provided by the preferred embodiment of the present invention and the existing flute body assembly after being decomposed, the fifth figure is a decomposition diagram showing the components of the mouthpiece assembly provided by the preferred embodiment of the present invention, and the sixth figure is a cross-sectional view of the mouthpiece assembly along the B-B section in the fourth figure. As shown in the fourth to sixth figures, a mouthpiece assembly 1 of a flute family musical instrument is used to be assembled on a flute body assembly 2 of a flute family musical instrument, and includes a mouthpiece tube 11, a connecting tube 12 and a mouthpiece crown 13.

The flute family musical instrument described in the present invention refers to any one of the musical instrument family groups with similar structure or timbre to the flute, that is, any one of the treble flute, alto flute, bass flute and piccolo. Most of the musical instrument family groups to which the flute family musical instrument belongs are three-section structures including a mouthpiece assembly 1, a flute body assembly 2 and a flute tail assembly (not shown), but a small number (such as the piccolo) are two-section structures including only a mouthpiece assembly 1 and a flute body assembly 2.

The mouthpiece 11 comprises a body 111 and a lip pad 112. The body 111 is an integral member having a closed end 111a and an open end 111b, and is provided with an opening OP, an air flow vibration chamber RC and a mouthpiece crown mounting groove AG. The opening OP is provided at the open end 111b.

The air flow oscillation chamber RC extends from the opening OP toward the closed end 111a and has a resonant concave surface RCS adjacent to the closed end 111a. The resonant concave surface RCS can be a hemispherical concave surface or an arcuate concave surface. In the hemispherical concave surface, the edge contour where the depression begins is circular, and the center of curvature is coplanar with the circular edge contour. The curvatures of the various parts of the arcuate concave surface can be equal or different, preferably the same curvature. The mouthpiece crown mounting groove AG is opened at the closed end 111a of the main body 111.

The lip pad portion 112 is integrally formed and protrudes from the main body portion 111 between the closed end 111a and the open end 111b, and is provided with a blowing hole BH connected to the air flow vibration chamber RC, so that a player's lips can approach to blow an incoming air flow BF into the air flow vibration chamber RC, and make the blown air flow BF vibrate and resonate on the resonant concave surface RCS to generate a blowing sound wave PSW.

Since the body 111 and the lip pad 112 are formed integrally with each other, the entire mouthpiece 11 is an integral component. Preferably, the mouthpiece 11 can be a wooden mouthpiece or a metal mouthpiece, that is, an integral component made of wood or metal. As computer numerical control (CNC) processing technology becomes increasingly mature, the mouthpiece 11 can be directly manufactured by cutting a wooden or metal column material using CNC processing technology.

The connecting tube 12 can be a metal connecting tube, which is inserted and fixed to the opening end 111b by means of snap-fitting or screwing, and extends out of the opening OP for assembly to the flute body assembly 2. The mouthpiece crown 13 can be installed and fixed to the mouthpiece crown mounting groove AG by means of threaded screwing or interference snap-fitting. In this way, the mouthpiece assembly 1 provided by the present invention can be maintained similar or identical in appearance to the mouthpiece assembly PA1 in the prior art shown in the first figure.

In summary, in the mouthpiece assembly 1 of the flute family musical instrument provided by the present invention, the mouthpiece tube 11 (composed of the body portion 111 and the lip pad portion 112) itself is an integrated component having a closed end 111a and an open end. Therefore, after an air flow vibration chamber is opened from the open end toward the closed end, the reverberation concave curved surface adjacent to the closed end in the air flow vibration chamber can always maintain a consistent distance from the open end, so as to ensure that the reverberation node position and the effective tube length can always be maintained consistent, thereby achieving the effect of maintaining a fixed pitch after long-term use.

In addition, by means of precision machining using CNC technology, an airflow vibration chamber RC with a precise effective tube length and a resonant concave surface RCS with a precise curvature can be accurately cut out, so that a flute family instrument equipped with the mouthpiece assembly 1 can have extremely high pitch when it is completed.

The above detailed description of the preferred specific embodiments is intended to more clearly describe the features and spirit of the present invention, but is not intended to limit the scope of the present invention by the preferred specific embodiments disclosed above. On the contrary, the purpose is to cover various changes and arrangements with equivalents within the scope of the patent application for the present invention.
