JP2023013360A - Muffled japanese drum, and muffling method of japanese drum - Google Patents

Abstract

To solve a problem of Japanese drums that there is no muffled Japanese drums because it is difficult to affix a vibration-absorbing material to a drum surface for Japanese drums that mainly use animal skins for the drum surface that produces beating sound, even though conventional muffling methods for percussion instruments mainly use the vibration-absorbing material affixed to the drumhead to muffle the sound.SOLUTION: A body shell of a Japanese drum includes polygonal or circular holes whose diagonal length or diameter is 30 mm to 150 mm, and a polygonal lid intended to plug the hole, where a diagonal length of the hole and the lid inside the body shell is 0 mm to 10 mm shorter than a diagonal length and a diameter of the hole and the lid outside the body shell. By inserting a sound absorbing material through the holes and sealing the holes with the lid, it is possible to reduce banging sound.SELECTED DRAWING: Figure 2

Description

The present invention relates to a Japanese drum and a Japanese drum silencing method for muting or reducing the beating sound.

Since the beating sound of percussion instruments is quite loud, when practicing in a general house without soundproofing equipment, the generated sound may annoy the neighbors. Especially at night, the noise generated was a problem, and it was not possible to practice sufficiently. Therefore, for percussion instruments such as drums, there are methods such as using a training drum set with a low beating sound, or placing a rubber pad on the drum head and beating the drum through the rubber pad. .

In the invention of Patent Document 1, a vibration absorbing material is attached to the drum head to muffle the sound. It is difficult to affix to the drum surface. The invention of Patent Document 2 produces a silencing effect by a three-layer structure consisting of a drum surface skin that produces a beating sound, a sound-absorbing member provided on the inner surface of the skin, and a plate-shaped member provided on the inner surface of the sound-absorbing member. However, due to its complicated structure, it is a practice-only drum that does not function as a normal Japanese drum.

In order to solve the above-mentioned problems, the invention according to claim 1 provides a drum body of a Japanese drum, a polygonal hole with a diagonal length of 30 mm to 200 mm, and closing the hole. and a polygonal lid, wherein the length of the diagonal on the inside of the trunk of the hole and the lid is 0 mm to 10 mm shorter than the length of the diagonal on the outside of the trunk of the hole and the lid, and from the hole. It is characterized by inserting a sound absorbing material and closing the hole with the lid to reduce the beating sound.

In the invention of claim 2, the body of the Japanese drum is provided with a circular hole having a diameter of 30 mm to 200 mm and a circular lid for closing the hole, wherein the hole is and the diameter of the trunk inside of the lid is 0 mm to 10 mm shorter than the diameter of the hole and the trunk outside of the lid, and a sound absorbing material is inserted through the hole and the hole is closed using the lid. It is characterized by reducing the beating sound by

The invention of claim 3 is the muffled Japanese drum of claim 1 or claim 2, characterized in that a recessed handle is provided on the outer side of the body of the lid.

The invention of claim 4 is the muffled Japanese drum of claim 1 or claim 2, wherein a lid magnet portion is provided inside the barrel of the lid portion, and a hole magnet is provided inside the barrel portion near the hole. and a part.

According to the invention of claim 5, the sound-absorbing Japanese drum according to claim 1 or claim 2 is used, and the cover is pulled out, the hole is opened, and a sound absorbing material is inserted through the hole. It is characterized by reducing tapping noise.

The invention of claim 6 is characterized in that the sound absorbing material of claim 1, claim 2 or claim 4 is urethane sponge, felt, wool, polyester or glass wool.

According to the present invention, a Japanese drum, which is difficult to mute, can be effectively muffled by a very simple method, and can be restored to a normal Japanese drum by taking out the muffling material. The idea of making a hole in the body 104 of the sacred Japanese drum and inserting a sound deadening material is an invention that cannot be easily realized by those skilled in the art.
