DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to increase or decrease the volume of a cup by changing the volume of the cup mechanically and steplessly so as to easily produce a wide range of sounds from low to high frequencies. Related to a mouthpiece for a metal wind instrument. The mouthpiece is a portion to be put on the mouth, which is connected to the tip of the metal wind instrument, and the mouthpiece blows out the sound of the instrument, so that it is also called a mouthpiece or a singing mouth.

[0002]

2. Description of the Related Art Generally, a mouthpiece for a metal wind instrument is constructed as shown in FIG.
As shown in FIG. 9, the upper cup 25 and the lower shank 26 are integrally formed in a funnel shape, and the shank 26 has a back bore 28 continuous from the cup bottom 27. Have been.

[0003] The reason that the shape of the mouthpiece is not changed in the past is that it is largely controlled by the function of the mouthpiece itself. In other words, this tone metal wind instrument is referred to the cup volume of the mouthpiece is large (deep) enough Kanade out bass easily, cup volume conversely small (shallow) Ru der those response rates out easily treble as
Is well known. Generally, beginners use a mouthpiece with a large cup volume. This is because sound is easy to emit and the pitch is stabilized. And when you need to improve your performance and get treble, use a small cup mouthpiece.

[0004] In short, it is extremely difficult for even a skilled person to produce both high and low ranges with a single mouthpiece. Therefore, the player should select a mouthpiece that is adapted to the musical piece as much as possible. To play. Players who are said to be excellent performers are performing with a unique technique that ordinary players can not do, that is, a technique like a masterpiece of lips and breath blowing. Even with such a name musicians, at present, it is depending on the music being played by changing the size of Ma Usupisu.

As described above, it is difficult for a player to prepare and prepare a large number of mouthpieces adapted to the music to be played in advance, and even if such a mouthpiece can be prepared, these mouthpieces cannot be tolerated. Does not meet all the conditions, such as physical and mechanical, for each corresponding music piece. This is because the volume of each cup is always constant even for a mouthpiece corresponding to a musical piece.

As described above, the mouthpiece tends to produce a low tone when the cup volume is large, and tends to produce a high tone when the cup volume is small. Therefore, even if the player selects a mouthpiece in accordance with the music to be played in advance, the mouthpiece cannot be replaced properly during the performance, which means that the player's technique must produce a low and high range. There is no.

Generally, each player selects a mouthpiece according to his / her compatibility, necessity, and adaptability to the musical instrument to be used, and sets a constantly constant cup volume by an embouchure method, breath control, lip vibration, and the like. The sound and pitch of the bass and treble range are produced with subtle adjustments. Skilled players have made such adjustments self-expression only over many years, and it must be said that it is extremely difficult to impose this adjustment on beginners.

[0008]

As described above, the mouthpiece is easy to produce a low range and a high range mainly due to the size of the cup volume. In other words, if the performance music has a low tone with a deep, dark tone as a whole, the player applies a mouthpiece with a large cup volume to the musical instrument, but the performance of the performance music is partially high. In order to produce a tone with a vibrant range and a bright glittering atmosphere, you must rely on the player's own technique each time.On the other hand, if the performance music is a high tone with a bright glittering atmosphere as a whole, As a player, a mouthpiece with a small cup volume is applied to the musical instrument.However, in order to produce a tone with a low tone range and a deep dark atmosphere partially in the performance music, the player's own technology You have to make full use of These techniques must be overcome by controlling the strength of the mouthpiece against the lips and subtle breath control, and when the conditions are poor, the above techniques may not be able to be controlled.

It can be said that this is because the configuration of the mouthpiece is invariable, and it is very useful for improving the self-expression unique to each player, that is, for improving the advanced technology.

[0010] However, the conventional mouthpieces have difficulties in teaching and learning performances for beginners, and many mouthpieces which can be adapted to a specific musical instrument used as described above or to different musical instruments. Has to be prepared.

The present invention has been developed in view of the above problems and the function of the cup volume. Even during the performance of the player, only the slight pressing force of the lips against the mouthpiece is changed.
Automatically, and the cup volume of those said mouthpiece by, by allowing changes steplessly, when the time to help out Kanade bass will increase the cup volume, to facilitate out Kanade treble cup The purpose is to reduce the volume to make it easier for beginners to acquire technical skills, and for skilled workers to respond to the pursuit of more advanced skills and richer self-expression.

[0012]

The gist of the present invention to achieve the above object is to provide a hollow inverted convex.

It is an object of the present invention to provide a mouthpiece for a metal wind instrument, wherein the mouthpiece slides up and down in a cylindrical body of a rim cup .

[0013] The present invention is based on the above configuration,
Connect previously not a Kappushi Yanku end Rukin genus wind instrument to use of to connect the mouthpiece to the instrument. At this time, the upper portion of the cup shank which engages tightly the lower part of Rimukappu is pressed by the restoring force of the elastic repulsion member, and joint
Ca Ppura are constrained by located at the lowermost end portion of Rimukappu, the telescopic cup volume up. Therefore, players in this state is likely response rates out dark tone of bass blows addressed mouth like a flange Trim.

Further, if a little pressed against the mouth brim Trim rebound body shrinks, subtle stretch cup volume pushed continuously while sliding the lower top of Rimukappu cup shank from the bottom at the same time To make it easier to produce a brilliant tone in the high range. And the mouth is Tsuba
If stop pressing against Jori arm, cup shank is pressed by the restoring force of the elastic repulsion member, and fitting mosquito Ppura <br/> over the full cow the function of the stopper, it is pushed back again to the lowermost end of Rimukappu To maximize telescopic cup volume. In this manner, the volume of the telescopic cup can be changed within the range of the stroke in which the cup shank closely fitted to the rim cup can slide steplessly within the rim cup.

Here, the term "sound" refers to the content of hearing running by sound waves, and refers to the sound waves themselves, and the pitch of the sounds has a property that differs depending on the frequency. In addition, "sound waves" are elastic waves generated by the vibration of the sounding body in the air or other sound medium, and are determined by the ratio of the frequency and intensity of the upper sound contained in the sound and the degree of attenuation thereof. The tone is determined.

[0016] As described above, telescopic cup according to the present invention is composed of a Rimukappu and cup shank, and stroke (longest cylindrical barrel of the cup shank predetermined range
Since the length of the part can be freely and continuously changed in a stepless manner, the volume of the telescopic cup slightly changes with this change.

The sound wave generated by the vibration of the lips is
The air in the telescopic cup is used as a medium to generate elastic waves and transmitted to the telescopic cup. This elastic wave, if there is more air in the telescopic cup, the resistance will be proportional and the damping will be greater,
Conversely, if the air inside the telescopic cup is small, the resistance is proportional and the degree of attenuation is small. Therefore, a large and deep telescopic cup has a large volume, so that it is easy to produce low tone and has a deep dark tone, and when the telescopic cup is small and shallow, it is easy to produce a high tone range and a bright tone.

According to the present invention described above, a single mouthpiece makes it easy to easily produce low-, mid-, and high-tone sounds, so that a beginner can easily learn the technology in a short time. In addition, the skilled person can pursue more advanced technology development. The upper cup shank may protrude into the Rimukappu, The setting of the joint mosquito Ppura may be a mechanical arrangement according screwing or Mitsugo with Rimukappu.

[0019] In summary, the present invention is combined tightly through the elastic repulsion member mosquitoes Ppushanku to Rimuka' flop, which joint cut
That form a stretched or squeezed cup by restrained puller
It is. Therefore, close the cup shank to the rim cup.
With a delicate pressing force of the lips against the rim cup
The rim cup can be stretched and slid in a stepless manner by only the strength.
Can be made. At this time, the movement of the rim cup
The coupling coupler moves along the annular collar of the cup shank.
