Summary:PROBLEM TO BE SOLVED: To provide a keyboard harmonica capable of adjusting a tone, without complicating the structure.SOLUTION: The opening ratio of a valve packing 40 of a keyboard harmonica 1 for a middle sound range SA2 and a high sound range SA3 is smaller than 1. By this, in a whistle room 10 corresponding to the middle sound range SA2 and the high sound range SA3, since the air flow hits the bulb packing 40 and an air flow route R is changed, the tones of the sounds of the middle sound range SA2 and the high sound range SA3 are adjusted to be mellow. Further, since the shape of an opening 41 of the bulb packing 40 is changed, the tone can be adjusted without complicating the structure.SELECTED DRAWING: Figure 3 【課題】構造が複雑化することなく、音色を調整することができる鍵盤ハーモニカを提供すること。【解決手段】鍵盤ハーモニカ１のバルブパッキン４０の中音域ＳＡ２および高音域ＳＡ３の開口率は１より小さい。このため、中音域ＳＡ２および高音域ＳＡ３に対応する笛室１０では、気流がバルブパッキン４０に当たり、空気流路Ｒが変更されるため、中音域ＳＡ２および高音域ＳＡ３の音の音色はメローに調整される。また、バルブパッキン４０の開口部４１の形状を変更するので、構造が複雑化することなく、音色を調整することができる。【選択図】図３
