Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tampo used for a woodwind instrument such as an oboe, and particularly to prevent breath leakage and improve sound quality and touch feeling.

[0002]

2. Description of the Related Art As shown in FIGS. 3 and 4, a woodwind instrument such as an oboe, a clarinet, a saxophone, etc. is opened and closed by a tampo 4 operated by a key mechanism 3 to open a sound hole 2 provided in a peripheral surface of a pipe body 1. By controlling it, a sound of a desired pitch is generated. The sound hole 2 is an opening of a branch pipe 5 projecting from the pipe body 1. The key mechanism 3 is the tube body 1
It is composed of a connecting pipe 7 which is rotatably supported by a pillar 6 which is erected on the outer peripheral surface of the rotating pipe 7 and which is rotated by a key (not shown), and a tampo plate 9 provided on the connecting pipe 7 via an arm 8. The tampo 4 is attached to 9 through a cushioning member 10.

Since the tampo 4 directly seals the sound hole 2, high sound tightness is required because the pitch, volume, timbre, etc. will not change and stable performance sound cannot be obtained unless it is sealed tightly. To be done. Therefore, the tampo 4 is made into a core material 13 by stacking a backing sheet 12 on the back surface of a generally disk-shaped felt 11 that is compression formed, that is, the center of the surface opposite to the sound hole 2, and this core material 13 is formed into a bag shape. What is covered with the covering material 14 formed of a material having airtightness is used (for example, Japanese Utility Model Laid-Open No. 3-2951 and Japanese Patent Laid-Open No. 07-056559). As the material of the covering material 14, usually, skin (leather of sheep and cows), bladder (built-in skin of sheep and goats) and the like are used.

5 and 6 are sectional views showing other conventional examples of tampo. The tampo 4 shown in FIG. 5 is obtained by wrapping the core material 13 with a skin as a material of the covering material 14. In the tampo 4 shown in FIG. 6, the same skin is used as the material of the covering material 14, and the bladder 15 is interposed between the surface of the felt 11 and the inner surface of the covering material 14.

[0005]

However, each of the above-mentioned conventional tampo for woodwind instruments has merits and demerits, and there is room for improvement. That is, in the tampo 4 shown in FIG. 4, since the bladder is used as the covering material 14, it has a high airtightness, but on the other hand, since it is a thin film, it easily breaks and has a problem of lacking durability. Further, there is a problem that the felt 11 is apt to change with time and durability is poor. In the tampo 4 shown in FIG. 5, the covering material 14
It has more durability than bladder because it uses a skin as the material of the skin, but the skin has numerous pores, which can cause a large leak of breath and cannot seal the sound hole with high airtightness. There was a problem. As a result, a stable performance sound cannot be obtained, and it is difficult to pronounce and the sound rises poorly. Also, the presence of pores reduces the sound resonance. In the tampo 4 shown in FIG. 6, the covering material 1
Using the skin as the material of No. 4, felt 11 and covering material 1
Since the bladder 15 is interposed between the pad 4 and 4, the impact when hitting the opening edge of the sound hole is smaller than that of the tampo shown in FIGS. 4 and 5, and a light touch feeling can be obtained.
Although it has a feature that it is excellent in airtightness and can prevent breath leakage, there is a problem in that the presence of pores in the covering material 14 stops sound reverberation and the sound quality is poor.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a woodwind instrument tampo which is improved in airtightness, sound quality and touch feeling. It is in.

[0007]

In order to achieve the above object, the present invention provides a felt having a front surface facing a sound hole, a mount which constitutes a core material together with the felt, and a bag-shaped covering material for covering the core material. In a woodwind instrument tampo provided with a bladder as a covering material, a skin is interposed between the inner surface of the covering material and the surface of the felt. In addition, the present invention is characterized in that the skin is formed in a bag shape and covers the outer peripheral portions of the front surface, the side surface, and the back surface of the felt which are not covered by the mount.

In the present invention, the covering material made of a bladder has high airtightness and prevents breathing. Since the skin has flexibility together with the covering material, it fits well with the opening edge of the sound hole and reduces the impact when hitting. Moreover, since the pores of the skin are covered by the bladder, the sound is not adversely affected.
