KEYBOARD HARMONICA

The present invention provides a keyboard harmonica capable of adjusting tones without the need for a complex structure. The aperture ratio of the valve packing 40 of a keyboard harmonica 1 is less than 1 for a midrange SA2 and a high range SA3. Therefore, flowing air strikes the valve packing 40 in reed chambers 10 corresponding to the midrange SA2 and the high range SA3 to change an airflow pathway R, thereby causing tones for the midrange SA2 and the high range SA3 to be mellow. Furthermore, since the shapes of the openings 41 of the valve packing 40 are modified, tones can be adjusted without requiring a complex structure. 提供一种键盘口琴，能够不使构造变得复杂地对音色进行调整。键盘口琴1的活瓣垫40的中音域SA2和高音域SA3的开口率比1小。因此，在与中音域SA2和高音域SA3对应的笛室10，气流吹到活瓣垫40上而使空气流路R发生改变，因此中音域SA2和高音域SA3的声音被调整为柔润的音色。并且，由于改变了活瓣垫40的开口部41的形状，能够不使构造变得复杂地对音色进行调整。
