Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a miute worn on wind instruments such as trumpets and trombones in order to weaken the blowing sound.

(Prior Art) In the past, miutes formed from thin sheets of light metal were mainly used for wind instruments.

(Problems that the invention aims to solve) Therefore, there are problems in that Miyuto is easily deformed or damaged when it accidentally collides with another object, and that the color is monotonous because it is limited to the material color, and that each sound range is The problem was that the damping effect on the sound was unbalanced, and because it was made of metal, only the high range remained and the low range was erased.

In view of the above-mentioned problems, the purpose of the present invention is to enhance the intensity characteristics and color effects, equalize the weak tone effect in each range, and improve the acoustic characteristics of the weakened blowing sound over the entire range, and To provide a mute for a wind instrument that can change the degree of a weak tone effect.

(Means for Solving the Problems) The Miute body of the Miyuto for wind instruments of the present invention has a front end edge of a base tube formed of a hard synthetic resin material into a substantially conical tube shape in order to be inserted into the mouthpiece of the wind instrument. In order to cover the front opening of the base cylinder, the head is removably connected to the rear end edge of a head formed of a hard synthetic resin material into a substantially bowl shape by screw means.

(Function) The rear end edge of the head part molded from a hard synthetic resin material is removed by a screw means from the front end edge of the base cylinder part molded from a hard synthetic resin material and inserted into the wind instrument's mouthpiece. The Mute body is releasably joined to produce a Mute body, and the Mute body is provided with a function of removing and replacing the head portion from the base cylinder portion, and the Mute body is provided with acoustic characteristics unique to a hard synthetic resin. .

(Embodiment) Next, an embodiment of the present invention will be described with reference to the drawings. In the figure, 1 is removably inserted into the blowing mouth K1 at the front end of the wind instrument K in order to weaken the blowing sound. It is a Miyut body of Miyut M which is made of a hard synthetic resin material pre-colored in an arbitrary color and is formed into a substantially conical cylinder shape so that the inner diameter gradually increases toward the front, and this base. Front opening 2 of cylinder part 2
A head part 3 is provided in a row in front of the base tube part 2 to cover the base tube part 2, and is formed into a substantially bowl-shaped shape from a hard synthetic resin material colored in the same color as the base tube part 2 or in a different color. are removably connected by a threaded portion 2b formed on the front end edge of the base cylindrical portion 2 and a threaded portion 3a formed on the rear end edge of the head portion 3. On the outer circumferential surface near the rear end of 2, an appropriate number of protrusions 4 to 4 made of cork material etc. are provided on the outer circumferential surface near the rear end of 2 to hold the base cylinder part 2 at a slight interval within the blowing opening K1.
4 are fixed in a spaced manner by adhesive or other means.

Note that various hard synthetic resins such as polyolefin, acrylic, polycarbonate, and ABS are used for the Miyuto body 1, and the hardness is selected depending on the required sound quality, range, etc.

Further, near the front end of the Miyuto body 1, one or more through holes are provided as necessary in order to adjust the sound quality and damping effect.

Next, the operation and effects of the embodiment having the above configuration will be explained.

In this example, in order to be inserted into the mouthpiece K1 of a wind instrument K, a base cylinder part 2 is made of a hard synthetic resin material and is formed into a substantially conical cylinder shape so that the inner diameter gradually increases toward the front;
In order to cover the opening at the front end of the base cylinder part 2, a head part 3 formed of a hard synthetic resin material into a substantially bowl shape is connected to a threaded part 2 formed at the front edge of the base cylinder part 2.
b, and a threaded portion 3 formed on the rear edge of the head portion 3.
a and is removably bonded to form a miute body 1.

Therefore, the design effect and appearance of the Miyuto M can be improved by coloring the Miyuto body 1 in any color, and the production of the Miyuto body 1 can be simplified.

In particular, since the Miyuto body 1 is made of a synthetic resin material whose density is lower than that of metal materials, the Miyuto body 1
The thickness of the Miyuto body 1 can be increased while avoiding an increase in the weight of the Miyuto body 1, the strength of the Miyuto body can be increased, and deformation and damage of the Miyuto body 1 can be suppressed.
By reducing the density and increasing the wall thickness, the vibration absorption performance of the Miyuto body 1 is improved, which increases the damping effect on the blowing sound, softens the tone, and balances the damping degree over the entire range. This eliminates the problem of partially erasing the range of the blowing sound or deteriorating the sound quality locally, and changes the acoustic characteristics of the blowing sound played while wearing Miyuto M from the low range to the high range. There are characteristics that can be improved overall over time.

In addition, since the base tube part 2 and the head part 3 are removably connected to form the miute body 1, the head part 3 can be replaced depending on the type of wind instrument, the required sound quality, range, etc. This makes it possible to change the acoustic characteristics of the Mute body 1, such as the weak tone effect of the blowing sound, the sound quality characteristics, the range characteristics, etc. Also, even if the head part 3 is damaged, the Mute body 1 can be replaced by replacing it. It becomes possible to reuse the body, which has the effect of extending the useful life of the Miyuto body.

(Effects of the invention) The present invention covers the front edge of the base tube, which is formed into a substantially conical tube shape from a hard synthetic resin material, and the front opening of the base tube, in order to be inserted into the mouthpiece of a wind instrument. The rear edge of the head part, which is molded into a roughly bowl-shaped shape from a hard synthetic resin material, is removably connected to the rear edge of the head part using a screw means to form a Miyuto body, thereby achieving the Miyuto color effect. In addition to being able to improve the acoustic characteristics and strength characteristics of the blowing sound, it also has the feature that the acoustic characteristics and damping effect of the blowing sound can be changed over the entire range, and the acoustic characteristics and damping effect of the Miyuto body can be easily changed.
