Description

[Detailed description of the invention] The present invention relates to brass instruments such as horns.

In conventional horns, for example, three adjustment valves are usually interposed in the main pipe connecting the mouthpiece and the bell, and by switching these adjustment valves as appropriate, a detour pipe corresponding to the switched adjustment valve is connected to the main pipe. The detour pipe is inserted in series with the detour pipe, thereby increasing the length of the pipe and lowering the pitch of the performance sound by an amount corresponding to the length of the detour pipe.

However, a rotary set of valves is generally used as the adjustment valve for conventional horns of this type, but since the cross-sectional shape of this valve is not circular with direct pressure, it is difficult to obtain a tone close to that of a natural horn. The drawback was that it couldn't be done.

In particular, with a double horn, in addition to the three adjustment valves mentioned above, the main pipe has two switching valves for switching between the Bb pipe and the F pipe, so it is possible to obtain a tone even closer to that of a natural horn. The drawback was that it couldn't be done.

This invention has been made in view of the above circumstances, and aims to provide a brass instrument that can obtain a tone closer to that of a natural horn and improve the tone, and includes a mouthpiece. and a bell can communicate with each other through two switching valves and an auxiliary pipe.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

1 and 2 show schematic structural views of a single horn, in which 1 is a mouthpiece, 2 is a bell, and these are connected by a main pipe 3.

Three normal adjustment valves/L' valves 4, 5, 6 are interposed in the main pipe 3, and detour pipes 7, 8, 9 are attached to these adjustment valves 4, 5, 6, respectively.

When the adjustment valves 4, 5, and 6 are switched by operating a key (not shown), the detour pipes 7, 8, and 9 corresponding to the switched adjustment valves are inserted in series into the main pipe 3. It has become.

Switching valves 10 and 1 are provided in a portion of the main pipe 3 located between the mouthpiece 1 and the adjustment valve 4 and a portion located between the bell 2 and the adjustment valve 6, respectively.
1 is interposed therebetween, and these switching valves 10 and 11 are connected by an auxiliary pipe 12.

When the switching valves 10 and 11 are switched simultaneously by operating a key (not shown), the sub pipe 12
A conduit is established through which the mouthpiece 1 and the bell 2 communicate.

Therefore, according to this single horn, by operating the keys corresponding to the adjustment valves 4, 5, and 6 in the state shown in FIG. When the key corresponding to .11 is operated, the mouthpiece 1 and the bell 2 communicate with each other via the secondary pipe 12, as shown in FIG.
A conduit containing only 11 degrees is formed, and as a result, a tone closer to that of a natural horn can be obtained.

Next, another embodiment of the present invention will be described with reference to FIGS. 3 and 4.

3 and 4 show schematic configuration diagrams of a double horn, in which 20 is a mouthpiece, 21 is a bell, and these are connected by a first main pipe (Bb pipe) 22.

The first main pipe 22 has three normal regulating valves 23 and 24.
゜25 is interposed, and these adjustment valves 23゜24
．． A detour pipe (not shown) is attached to each of the pipes 25.

Further, the first main pipe 22 includes a normal switching valve 26,
27 is interposed therebetween, and these switching valves 26 and 27 are connected by a second main pipe (F pipe) 28.

The second main pipe 28 has three normal regulating valves 29, 30.
, 31 are interposed, and these regulating valves 29, 30
, 31 are each provided with a detour pipe (not shown).

Furthermore, the mouthpiece 20 of the first main pipe 22
Second switching valves 32 and 33 are interposed between the bell 21 and the switching valve 26 and between the bell 21 and the switching valve 27, respectively. The valves 32 and 33 are connected by an auxiliary pipe 34.

Therefore, according to this double horn, in the state shown in FIG.
By operating the keys corresponding to the adjustment valves 24, 30, and 25, 31, the same performance sound as in the past can be obtained.
, 33, the mouthpiece 20 and the bell 21 communicate with each other via the auxiliary pipe 34, as shown in FIG. This allows you to obtain a tone that is closer to that of a natural horn.

In addition, in each of the above-mentioned embodiments, if a detour pipe can be inserted in series into the sub pipe 12.34, the length of this pipe can be changed as appropriate.

Furthermore, in each of the embodiments described above, the switching valve 10.1
If valves 1, 32, and 33 are used that have less cross-sectional deformation than normal valves, a tone even closer to that of a natural horn can be obtained.

Further, in each of the above-described embodiments, the present invention is applied to a horn, but the present invention is not limited thereto, and can be widely applied to brass instruments such as trumpets.

As explained in detail above, the brass instrument according to the present invention has a configuration in which the mouthpiece and the bell can communicate with each other via the two switching valves and the auxiliary pipe.
It is possible to form a conduit with only one valve,
Therefore, it is possible to improve the timbre, for example, to obtain a timbre closer to that of a natural horn.
