Abstract

A sound changer for a brass instrument mounted on a bell of a brass instrument efficiently collects sound inside the sound changer without affecting standing waves inside the instrument, and directs the sound toward the outside world. It is to provide a new acoustic modifier that can radiate unprecedented metallic special sounds at a high volume.
A sound modifier for a brass instrument mounted on a bell of a brass instrument has a bottom portion and a cylindrical body, and the bottom has a communication hole having a size that does not affect standing waves inside the instrument. The most main feature of the present invention is to have a bell-shaped projection of the brass instrument from the communication hole toward the inside and outside of the acoustic modifier.

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an acoustic modifier for a brass instrument.
[0002]
[Prior art]
There are various types of brass sound modifiers mounted on a brass instrument bell. There are two types of tone changers: one is to change the original sound of brass instruments into various tones by installing those sound modifiers, and the other is to mute the sound. Are indistinguishable, and both are referred to collectively as mute or mute.
[0003]
There are various types of mute for the purpose of changing the tone, such as straight, cup, wah-wah, and the like, but the tone changes variously due to the material and shape. In other words, music always seeks a variety of acoustic modifiers, seeking a variety of timbres. On the other hand, it is important to mute a mute for the purpose of silencing while simultaneously improving the silencing performance and natural feeling of playing.
[0004]
As shown in FIG. 3, some conventional products have a bell-shaped or bowl-shaped projection of a brass instrument directed outward from a mute tip or bottom. The role of the protruding portion is the same as that of the outer bell 4 of the present invention, and is a role of radiating the sound inside the mute to the outside world. However, since these do not have a structure for efficiently collecting the sound inside the mute, there is a disadvantage that a sufficient volume cannot be obtained as a result.
[0005]
When the communication hole 5 which is the outlet of the sound is enlarged for the purpose of increasing the volume radiated to the outside with respect to the conventional product having a protrusion at the tip or bottom of the mute, a standing wave inside the musical instrument is generated. This causes a serious problem that it is impossible to perform even at the correct pitch.
[0006]
[Problems to be solved by the invention]
The problem to be solved by the present invention is to provide a brass instrument sound modifier mounted on a bell of a brass instrument, which efficiently collects sound inside the acoustic modifier without affecting standing waves inside the instrument. The present invention provides a new sound modifier that can emit a special metallic sound at a high volume to the outside world.
[Means for Solving the Problems]
The present invention relates to a brass instrument sound modifier mounted on a bell of a brass instrument, comprising a bottom portion and a cylindrical body portion, wherein the bottom portion has a communication hole having a size that does not affect standing waves inside the instrument. The most main feature of the present invention is to have a bell-shaped projection of the brass instrument from the communication hole toward the inside and outside of the acoustic modifier.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
At the bottom of the conventional mute for brass instruments, a communication hole with a size that does not affect the standing wave inside the instrument is provided, and from the communication hole, a bell-shaped projection of the brass instrument going in and out of the acoustic changer It was realized by the structure equipped.
[0009]
【Example】
FIG. 1 is a sectional view of a sound modifier according to a first embodiment of the present invention. 1 is a trunk, 2 is a bottom, 3 is an inner bell, 4 is an outer bell, 5 is a communication hole, 6 is a bell of a brass instrument, and 7 is a packing. In FIGS. 2 and 3, the same numbers indicate the same parts.
[0010]
The inner bell 3 efficiently collects the sound inside the sound modifier, and the communication hole 5 having a size that does not affect the standing wave inside the musical instrument allows the treble component of the collected sound to selectively pass therethrough. Bell 4 emits amplified radiation. As a result, unprecedented metallic sound can be emitted at a high volume. Since the present invention is provided with a communication hole that does not affect the standing wave inside the musical instrument, the description of the standing wave inside the brass instrument is omitted.
[0011]
The inside diameter of the communication hole 5 that does not affect the standing wave inside the musical instrument of the second embodiment shown in FIG. 2 is 9 mm, but a musical instrument in a high-tone range such as a trumpet requires a communication hole having a smaller diameter. In addition, a low-pitched instrument such as a tuba has a larger diameter communication hole. These actual values vary depending on the type of acoustic modifier and the acoustic characteristics of the corresponding musical instrument. Therefore, it is not a constant value.
[0012]
The shape of the inner bell 3, which plays a role in efficiently collecting the sound inside the acoustic modifier, is not limited to the bell shape of a brass instrument, but may be a bowl shape, a funnel shape, or the like. The timbre and volume can be changed depending on the shape and size of each.
[0013]
The shape of the outer bell 4 is not limited to the bell shape of a brass instrument, but may be a bowl shape, a funnel shape, or the like. The timbre and volume can be changed depending on the shape and size of each.
[0014]
By changing the length and size of the communication hole 5 within a range that does not affect the standing wave inside the musical instrument, it is possible to change the sound to be selectively transmitted and its volume. In the case of a long and small communication hole, the treble component increases, but the volume decreases. Conversely, in the case of a short and large communication hole, the bass component increases and the volume increases.
[0015]
In a second embodiment shown in FIG. 2, the present invention is applied to a brass silencer for silencing a brass instrument.
[0016]
Originally, a muffler for brass instruments intended for silencing leaks a whisper-like volume to the outside world. If the structure of the present invention is implemented in this silencer, it is possible to extract only high-frequency components from the loud sound being played inside the musical instrument, so that only metallic sounds are radiated at a high volume to the outside world. It becomes possible. The sound is metallic, a very special bean. The same metallic sound as the so-called horn's geschtop playing technique can be generated at a large volume, and all brass instruments can obtain new sounds that have never been seen before.
[0017]
【The invention's effect】
As described above, the brass instrument sound modifier of the present invention can include a metallic sound in the tone of the conventional tone modifier for the purpose of changing the tone, so that various tone changes can be obtained. It can be realized. As a result, the present invention is positively effective for music itself that requires diversification of sounds. On the other hand, in a silencer intended for silencing, since the sound leaking to the outside is very small, only a metallic sound can be radiated to the outside at a large volume. In particular, since this new and shocking tone is a sound that is enough to surprise everyone, there is a great possibility that it will be used in future music.
