Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention uses a continuous sponge, a rubber sound-insulating sheet, a sound-insulating material UK, a vinyl sheet, an acrylic plate, Styrofoam, etc. to make a cylinder, and put a wind instrument such as a saxophone in it for practice The present invention relates to a soundproofing device devised to reduce noise when doing.

[0002]

2. Description of the Related Art A conventional soundproofing technique for a saxophone, a clarinet, etc. is to cover a musical instrument with a cloth bag. Therefore, the effect is not sufficient, and the practice at home is considerably limited, and in the end, it was forced to practice in a studio with a soundproof room.

[0003]

SUMMARY OF THE INVENTION In order to solve the drawbacks of the present invention, a special box focusing on how the soundproofing is enhanced so that the surroundings will not be bothered even if they practice at home. With the idea of putting the entire instrument inside, I proceeded with research on the container development.

[0004]

In order to improve the soundproofness, it is necessary to focus on the thickness and tightness of a container for a wind instrument. As a result of an experiment on what kind of material is used and how to combine it in order to obtain the effect, a continuous pow sponge is made into a cylinder of a single to triple structure, and a wind instrument is placed in it. When I put it in, I discovered that if the inner diameter of the continuous pow sponge cylinder was made as close as possible to the thickness of the wind instrument, a higher soundproofing effect could be obtained. After wrapping the cylinder with a rubber sound insulation sheet, etc., cover the upper and lower parts with a continuous sponge, a rubber sound insulation sheet, and an acrylic plate, and then make the whole with a rubber sound insulation sheet that is one size larger. It was found that it is effective to put it in another cylinder and put the lids of the same structure on the upper and lower parts again to make the entire soundproofing device into a double structure. Furthermore, in order to prevent sound from the upper and lower parts, it was discovered that a greater effect can be obtained by covering the acrylic plate with a continuous paw sponge and a black cell sponge having the same diameter and thickness as the acrylic plate.

[0005]

Since the present invention is configured as described above, the sound of the wind instrument can be attenuated to about one-third to one-fifth of the original sound. You can practice wind instruments freely without any.

[0006]

EXAMPLE First, a continuous paw sponge cylinder having a single to triple structure was manufactured by simply rolling the continuous pow sponge sheet into three layers because the wind instrument used for carrying out the present invention was a linear and rod-shaped soprano saxophone. However, if the shape of the wind instrument has a unique shape like the alto saxophone, you can make a cylindrical mold according to the shape of the instrument and pour it into the shape, or repeat it. The pow sponge cylinder does not necessarily have a triple structure as long as it is shaped to have a sufficient thickness. The relationship between the inner diameter of the continuous pong sponge cylinder and the thickness of the wind instrument is that if the wind instrument is completely attached to the inner diameter of the cylinder, the sound itself will not be produced, and it will be difficult to hold the scale key with your finger. Become. Therefore, in order to allow the fingers of both hands to move freely and yet to produce the full scale of the instrument, in order to make the inner diameter of the cylinder slightly larger than the thickness of the instrument, and to make the movement of the fingers smoother, The part of the inner diameter of the cylinder where the finger hits was dented according to the movement and size of the finger. Next, the material that wraps around the continuous paw sponge cylinder and the material that creates the second soundproof cylinder are rubber soundproof sheets with a thickness of 1 to 5 mm, soundproof material UK, vinyl sheets, etc. are combined. However, since the continuous paw sponge fulfills most of the soundproofing function from the side, there was no difference in the effect of any combination of materials, so weighting was emphasized and it was about 1 mm to 2 mm. The use of rubber sound insulation sheets is realistic. Also, the size of the second soundproof cylinder is determined so that there is a clearance of about 2 cm between the first soundproof cylinder and the second soundproof cylinder. When the pow sponge sheet was attached, further soundproofing effect and strength against external impact were obtained. It should be noted that the continuous paw sponge cylinder and a part of the first and second cylinders are cut out and a rectangular window is opened and a transparent vinyl sheet, an acrylic plate, or the like is attached to the part, or the side surfaces of the first and second cylinders. We are also implementing methods such as making the entire part transparent so that the position of the finger of the scale key can be confirmed. Further, although the soundproofing effect is slightly inferior, if importance is attached to weight reduction, a method in which the continuous paw sponge cylinder is made of expanded polystyrene or urethane can be implemented. Since the cylindrical soundproofing device discovered that the leaking sound flowed in the vertical direction rather than the side direction, it was necessary to strengthen the soundproofing function especially at the upper part,
The acrylic plate on the upper lid was covered with various materials such as lead-based soundproofing sheet to perform soundproofing reinforcement work.
The most effective combination was a continuous paw sponge having a thickness of about 1 cm and a black cell sponge having a thickness of about 1 cm covering the upper part of the sponge. In addition, in order to stabilize the wind instrument to some extent inside the soundproofing device, an arc-shaped hook made of styrene foam was installed inside. Also, in order to absorb the water vapor that falls from the wind instrument during practice, a moisture absorbing cloth was attached to the bottom inside the device with Velcro. The drawing shows a soundproofing device for a linear soprano saxophone, but the unique shape of the alto saxophone is that the neck and mouthpiece part are curved and the mouth is blown from the side, this shape In order to cope with the above, the entire upper part of the soundproofing device may be manufactured in a diagonally sliced form, and the upper lid may be mounted on the upper part in a tilted manner. When practicing, in the case of the straight type, the entire soundproofing device can be slanted on the floor, and in the case of the alto type, it can be practiced in a sitting position by standing upright.

EFFECTS OF THE INVENTION Since the present invention has the above-mentioned structure, even if the user does not have to go to a studio or a place with few people and private houses because of concern about noise, he / she can feel free and comfortable in his / her room. You can practice wind instruments with your posture. Especially, it has a remarkable effect on the soundproofing of the saxophone, which has been a difficult problem until now. Therefore, the practice time for many saxophone players and clarinet players is significantly extended,
It can contribute to the upbringing of wind instrument players in the future.
