Description

[Background technology]

[0001] This invention relates to a Japanese drum that silences or reduces the sound of hitting.

[0002] The sounds produced by percussion instruments can be quite loud, so when practicing in a regular home without soundproofing, the noise can be a nuisance to neighbors. This noise is particularly problematic at night, making it difficult to practice properly. For this reason, people have resorted to using training drum sets that produce quieter sounds, or placing rubber pads on the drumheads and striking the drums through the rubber pads.

[0003] [Patent Document 1] Utility Model Registration No. 3004768 [Patent Document 2] Patent Publication No. 2010-78661 Summary of the Invention [Problem to be solved by the invention]

[0004] The invention in Patent Document 1 deadens sound by attaching a vibration-absorbing material to the drum head, but it is difficult to attach a vibration-absorbing material to the drum surface of Japanese drums, which mainly use animal skin for the drum surface that produces the percussion sound. The invention in Patent Document 2 creates a deadening effect with a three-layer structure consisting of the drum skin that produces the percussion sound, a sound-deadening member attached to the inside of the skin, and a plate-shaped member attached to the inside of the sound-deadening member, but the structure is complex and the drum is only meant to be used for practice and does not function as a regular Japanese drum. [Means for solving the problem]

[0005] In order to solve the above problem, the invention described in claim 1 comprises a polygonal hole (excluding a triangle) on the body of a Japanese drum, with all diagonal lengths of 30mm to 200mm, or a triangular hole with a side length of 30mm to 200mm, and a polygonal lid intended to cover the hole, wherein the length of the diagonal on the inside of the body of the hole and the lid is 0mm to 10mm shorter than the length of the diagonal on the outside of the body of the hole and the lid, and sound-absorbing material is inserted into the inside of the body of the Japanese drum through the hole, and the hole is covered with the lid, and the sound-absorbing material entering the inside of the body reduces the tapping sound.

[0006] The invention of claim 2 is characterized in that the body of a Japanese drum is provided with a circular hole with a diameter of 30 mm to 200 mm, and a circular lid intended to cover the hole, the diameter of the hole and the lid on the inside of the body being 0 mm to 10 mm shorter than the diameter of the hole and the lid on the outside of the body, sound-absorbing material is inserted into the inside of the body of the Japanese drum through the hole, and the hole is covered with the lid, and the sound-absorbing material entering the inside of the body reduces the sound of beating.

[0007] The invention of claim 3 is a sound-reducing Japanese drum of claim 1 or claim 2, characterized in that it has a concave handle on the outside of the body of the lid.

[0008] The invention of claim 4 is a sound-reducing Japanese drum of claim 1 or claim 2, characterized in that it has a lid magnet part on the inside of the body of the lid part, and a hole magnet part on the inside of the body near the hole part.

[0009] The invention of claim 5 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.

[0010] According to this invention, Japanese drums, which are difficult to silence, can be silenced effectively in a very simple way, and by removing the sound-deadening material, the drum can be restored to a normal state. The idea of ​​drilling a hole in the body 104 of a sacred Japanese drum and inserting sound-deadening material is not something that a person skilled in the art could easily come up with.
