Description

  The present invention relates to a harmonica, and more particularly to a four-tone harmonica.

  FIG. 6 is an exploded perspective view showing a schematic configuration example of a conventional harmonica (compound sound). The harmonica 3 includes lead mounting plates 32 and 33 of the harmonica bodies 31 and 2 and covers 34 and 35 of the 2.

  The harmonica main body 31 includes a plurality of transverse partitions 312 on both sides of a horizontally elongated partition plate 311 extending in the left-right direction, and a bottom plate 313 that is in contact with the far end of the partition 312 over the entire length of the partition plate 311. A ventilation passage 314 of a sound generating portion that emits a fundamental tone is formed in a line along the surface.

  The two lead mounting plates 32 and 33 are bridged by a plurality of partitions 312 from above and below, and each air passage 314 is defined as an air chamber that opens only forward. A plurality of leads 321 and 331 correspond to the air passages 314 on the two lead mounting plates 32 and 33, and a lead mechanism that gradually shortens to the right according to the scale. The leads 321 and 331 are attached to the back and front surfaces of the mounting plates 32 and 33 in accordance with the inflow (blowing) and outflow (sucking) of air into the air chamber, and are vibrated by the air flow and predetermined. The sound of the scale can be generated. The difference in the pitch of the harmonica can be determined by adjusting the vibration elasticity according to the length, thickness, and shape of the lead.

  The covers 34 and 35 are provided so as to cover the lead attachment plates 32 and 33 from above and below, respectively, so as to protect the lead mechanism and the like therein, and to enhance resonance in the air chamber.

  This multi-tone harmonica 3 can produce a fundamental tone with a wide range of scales from low to high. 7 and 8 are diagrams showing examples of sound arrangements for a 24-hole, C-tone harmonica. In the figure, as the direction of airflow during performance, an arrow “↑” indicates an expiratory sound and “↓” indicates an inspiratory sound. The direction of FIG. 7 is an example of a scale of single-tone harmonica, and the same sound is produced when blowing or sucking in both upper and lower holes. FIG. 8 is an example of a scale of a multi-tone harmonica, and when the upper and lower holes are blown or sucked, a different sound is produced eight times. If the lead thickness is adjusted, even if the same sound is produced, it will resonate and resonate.

  However, this multi-tone harmonica needs to be used in combination with a harmonica that produces multiple semitones with different keys when performing transpositions such as classical music or jazz, or a song that uses a lot of semitones. There are considerable limitations.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a harmonica from which a harmonious chord can be obtained.

  In order to achieve the above object, the harmonica according to the present invention has a horizontally long base plate extending in the left-right direction and a plurality of partition walls perpendicular to the left-right direction, and a predetermined air chamber at the upper and lower portions of the base plate.

One slot and a second slot are opened, and a first lead and a second lead are provided with the respective first ends fixed to the first slot and the second slot. And de mounting plate, and characterized in that it comprises a.

  In this configuration, it is preferable that the tip of each partition is formed to be shorter than the opening tip of each partition wall, that is, the air chamber is opened in the hole.

  Further, it is preferable that the first lead and the second lead emit a sound whose pitch is different eight times. In particular, each lead in the upper hole and each lead in the bottom hole have a different sound eight times. A configuration that emits the light is preferable.

  Further, the first lead and the second lead are preferably configured so as to emit the same sound once, that is, the first lead and the second lead having the same sound each sound differently. The configuration is preferable.

  Moreover, two covers from above and below are provided on the harmonica body so as to cover the two lead mounting plates, respectively, so that dust and the like can be prevented from entering inside, and resonance in the air chamber can be amplified. .

  With the above configuration, in the harmonica, four slots, that is, four air chambers are formed vertically by each partition, and the left and right adjacent leads can emit the same sound or eight different chords by blowing or sucking. As a result, it is possible to produce a more harmonious sound. Therefore, a harmonica suitable for performance can be provided.

It is partitioned. In this example, the front end portions 471 and 481 of the partitions 47 and 48 are in positions where they are drawn into the inside of the opening front end portions 431 of the partition walls 43. Further, the bottom plate 42 stands upright along the X direction and in a direction perpendicular to the base plate 41 and the partition wall 43 to close the rear end portions of the holes 45 and 46, and the depths of the holes 45 and 46 are deep. The slope is inclined so as to gradually decrease from left to right.
