Description

The present invention relates to an improvement in clarinet.

[Conventional technology]

Clarinets have evolved in the course of their development. This is true for the clarinet body, its geometry and the choice of materials, for example for the tendon mechanism. Clarinets are known in which the holes have a different diameter from part to part, unlike the original bore of a sound tube, which had a constant diameter. Furthermore, the individual parts can be configured in a conical shape. A sound tube configured in this way aims to achieve a particular clarity of the individual notes in all ranges, in particular in the 12-tone scale and in the higher range.

It is also known to provide a headpiece (bale tube) located between the clarinet's mouth and the upper tube with a sound hole which can be closed and opened by an operable tendon. This is intended to provide clean sound quality and wide sound range.

All of these known measures require a large and dangerous work burden, especially on the clarinet's upper tube and its tendon mechanism. Therefore, it is extremely difficult to make subsequent changes and adaptations to the tuning and timbre of the clarinet.

[Problems to be solved by the invention]

The present invention provides an improvement. In this case, it is based on the recognition that in the conventional clarinet, the effective proportion of the clarinet to the head piece of the total length of the clarinet is relatively small, however, the head piece is significantly important for the tuning and tone of the clarinet.

The aim is therefore to make the proportion of the length of the clarinet headpiece as large as possible. This is only possible with a limited amount of extension of the headpiece.

Conventionally, the head piece is connected to the mouth and the upper tube by a tenon with a hole firmly connected to the mouth and the upper tube. The outer diameter of the perforated tenon is then significantly smaller than the outer diameter of the mouth or upper tube. Conventionally used head pieces are provided with holes on both end faces thereof, which are adapted to the diameter of the perforated tenon and the length of the perforated tenon. By inserting a tenon with a hole in this hole,
An airtight bayonet connection is formed between the clarinet's mouth, headpiece and upper tube.

[Means for solving the problem]

According to the invention, the head piece is provided with a perforated tenon on each of its two end faces, which itself can be hermetically inserted into the corresponding holes of the upper tube and the mouthpiece. Is achieved by

By providing a tenon with holes on both end faces of the head piece, the effective pipe length of the head piece is increased by a factor of five. By this means, the invention significantly enhances the effect of the headpiece on the clarinet's tuning and timbre. This solution makes it possible to adapt the clarinet player's wishes for tuning and timbre by changing the longitudinal holes in the clarinet's head piece afterwards.

The solution according to the invention is significantly improved compared to the conventional adaptation method, which could only be intended for a subsequent change in the upper well of the instrument. This is because the invention eliminates risky subsequent changes in the vertical hole at the top of the instrument. The solution according to the invention is particularly meaningful in expensive clarinets, since the production of the upper part of the musical instrument requires extreme handicrafts and extreme precision.

〔Example〕

Next, the present invention will be described in detail with reference to the drawings showing a conventional example of a clarinet and an embodiment based on the present invention.

FIG. 1 and FIG. 2 show the connecting portion of the clarinet's singing mouth 1, the head piece 3 and the upper tube 6 in the order of assembly from top to bottom.

For a better understanding of the invention, the parts used for direct bonding are depicted in cross-section. The tendon mechanism is not shown. In the known clarinet shown in FIG. 2, the end of the mouth 1 is a tenon 2 with a hole, the diameter of which is smaller than the diameter of the mouth 1 and the head piece 3. The headpiece 3 is provided with a hole 4 on its end face on the side facing the mouth 1, which hole matches the diameter and length of the perforated tenon 2. Similarly, a hole 5 is provided on the end face on the side facing the upper tube, and this hole is used for accommodating a perforated tenon 7 of the upper tube 6. The bore of the clarinet is shown in this prior art as a cylindrical bore with a constant diameter. However, other hole configurations can be used, for example, different hole diameters and / or conical holes. As can be seen from FIG. 2, the proportion of the effective length of the longitudinal hole is relatively small in the region of the head piece 3.

In the case of the invention according to FIG. 1, a perforated tenon 8 which can be inserted into the hole 9 of the clarinet's upper tube 6 can increase the proportion of the effective length of the vertical hole of the headpiece 3. Such a construction is known from U.S. Pat.
However, this U.S. patent deals with a different problem than the present invention, namely the improvement of the bayonet connection of the individual parts of the clarinet.

According to the invention, the head piece 3 is provided with a perforated tenon 8 on both end faces thereof, the perforated tenon 8 corresponding to the corresponding hole in the mouthpiece 1 and the corresponding hole in the upper tube 6. Pluggable. With this arrangement, the ratio of the effective length of the vertical hole in the head piece 3 becomes about 5 times, and therefore, the influence of the head piece on the tuning and tone of the clarinet is maximized. For the first time, the invention eliminates the adjustment step in the clarinet upper tube.
