Janggu with a wide range and improved treble and treble stability

摘要

Janggu according to the present invention is coated with a large number of plate-like particles on the outer surface of the resonator, thereby improving the range of the frequency band of the sound emitted by the hitting of the chaff and the north side, thereby securing and controlling a higher treble frequency band. . In addition, the noise generated from the sound is reduced, the main hitting sound is clear and clear, and it lasts longer, and the noise that can be further included in the low sound is minimized. In addition, it has an effect of improving stability at a high-pitched tone with a high frequency band, and having high stability to continuously maintain an excellent initial sound over a long period of time even when continuously emitting sound in a high-pitched region with a high frequency.
