Description

  The present invention relates to a slide-type chromatic harmonica that can generate two kinds of scales, a major scale and a semitone higher than this by moving a slide lever.

  The chromatic harmonica has a slide lever between the main body and the mouthpiece. The main body has a large number of whistle chambers each having a lead as a sounding body, and a large number of blow holes for blowing and sucking air into each whistle chamber are provided in two rows in the vertical direction. One row of whistle chambers has a major scale sound arrangement, and the other row of whistle chambers has a semitone scale arrangement. A lead plate is fixed outside each whistle chamber row. The lead plate has a sound generation window corresponding to each whistle chamber, and a lead corresponding to each pitch is fixed on each sound generation window. Two sound generation windows are provided within the width of one whistle chamber. There are two types of reeds: a blow reed that produces sound by blowing operation, and a respiration lead that produces sound by sucking operation. Two respiration leads are arranged on the lead plate side by side in each whistle chamber. The The blowing reed is positioned on the lead plate inside the whistle chamber, and the corresponding blow-off valve is fixed on the lead plate outside the whistle chamber. The suction lead is disposed on the lead plate outside the whistle chamber, and the corresponding suction / release valve is fixed on the lead plate inside the whistle chamber. In chromatic harmonica, by moving the slide lever, either the major scale whistle chamber row or the semitone scale whistle chamber row can be closed and the sound of either scale can be selectively produced. (For example, Patent Document 1). Here, “up / down”, “left / right” means up, down, left, and right as viewed from the performer in the harmonica performance state.

JP 2004-219732 A

In the above-described conventional chromatic harmonica, two reeds and two reed valves corresponding to these are arranged side by side in the width dimension of one whistle chamber. Reed and valve installation space is limited within the width of the whistle chamber. If the left and right widths of the main body are constant, the left and right widths of the respective whistle chambers arranged in a row cannot be increased, and therefore the size of the lead as the sound generator cannot be freely increased.
Therefore, the invention according to this application can increase the installation space of the lead and increase the degree of freedom of the size of the lead by substantially expanding the width of the whistle chamber without increasing the width of the harmonica body. It aims to provide a chromatic harmonica that can be used.
