Description

[Detailed description of the invention] The present invention relates to a Japanese drum that has a good resonance and produces a good hitting sound (tuning sound) no matter where you hit it, even when hitting the edge when getting into tune. The configuration will be described in detail with reference to the accompanying drawings as follows. A locking step part 2 is provided around the outside of the opening edge at both ends of the body 1, a core bar 3 is placed around the locking step part 2, and a skin 4 is stretched on both sides of the body 1.

The core metal 3 in the drawing is a wire rod wrapped with vinyl tape 5. (It may be covered with a vinyl tube.) An uneven surface 6 extending in the circumferential direction is formed in the height direction inside the body 1 in the drawing to enhance the acoustic effect.

In the figure, 7 is a rivet and 8 is a nail.

In order to mass produce this body 1, it is preferable to mold it in plastic.

Generally, when playing the drum, the rim of the drum is struck to maintain the rhythm.

When you hit it, it makes a high-pitched, rattling sound, making it well tuned.

However, if you hit the edges for a long period of time, they may become dented.
If it is chipped or tightened, the hitting sound changes depending on where it is hit, making it impossible to produce a balanced tone sound.

In this regard, the present invention forms a locking step 2 on the outside of the opening edge at both ends of the body 1, and a core bar 3 is provided on this locking step 2 to prevent denting, chipping, and tightening caused by the impact of the edge. You can produce a well-balanced tone no matter which part you hit.

Furthermore, since the core metal 3 is struck, a higher impact sound than the conventional impact sound can be obtained.

In addition, by providing this core metal 3, the openings at both ends of the body 1 are tightened, so it has excellent practical effects such as producing a more resonant hitting sound even when hitting the hitting surface of the leather. It is something.

Since this core metal 3 is locked to the locking step portion 2, it is reliably fixed in a fixed position.
