Abstract

The invention provides a mini-chord harmonica which is composed of frets, an upper sound hole plate, a lower sound hole plate, an upper cover plate, a lower cover plate and cover plate screws; the upper sound hole plate and the lower sound hole plate with different musical scales on the frets of the harmonica are installed at two sides of the frets, and are fixed by screws of the frets; two layers of terylene thin films are arranged at the back side of the sound hole plates, and play roles of a spring and protecting the terylene thin films at the inner layer, thus achieving the aim of no air leakage, thus the harmonica is labor saving for playing, has accurate and sound voices. Each hole for the mini-chord harmonica provided by the invention is composed of a chord, is suitable for ensemble and reprise of a band, takes the responsibility of a set-off and accompaniment of an inner chorus part, the musical rhythm can be increased, the sound and volume can be enriched, and harmony effects which can not be comparable with the solo-type harmonica can be played.

Description

Mini chord mouth organ

Technical field: the present invention relates to the special harmony accompaniment mouth organ of a kind of structure, particularly relate to a kind of mini chord mouth organ.

Technical background: it is bigger that present chord mouth organ exists volume, carries difficulty, and the Major chord scale that plays out when playing wind instruments is inaccurate, drawbacks such as the hoarse and easy gas leakage of volume.

Summary of the invention: purpose of the present invention will provide a kind of chord mouth organ exactly, and it can overcome the above existing problems of present mouth organ well.The object of the present invention is achieved like this, mini chord mouth organ by the qin lattice, go up grill, down grill, cover plate and cover screw are formed up and down, it is characterized in that: on the mouth organ qin lattice respectively by two different scales on grill, down grill is contained in qin lattice both sides, and by qin lattice screw retention; Grill adopts brass sheet to be stamped to form, the tone reed of the different scales of welding on brass sheet, the grill reverse side is provided with double-deck mylar, on double-deck mylar, added a strata ammonia ethene particulate, make its surface galling, purpose is to leave certain space each other when two-layer mylar is overlapping, the air-flow ratio be easier to by; Outer field mylar is red film, covers on the film of nexine, mainly plays the effect of spring and protection nexine mylar.Thereby reach gastight purpose, make it to play wind instruments laborsaving, it is accurate, loud and clear to pronounce.The mini chord mouth organ of the present invention, each hole all is made up of a chord, and it is applicable to that band instrumental ensembles and ensemble, serves as setting off and accompanying of interior part, and it can strengthen the rhythm of melody and enrich VDA.Can play out that solo class mouth organ can't match in excellence or beauty and sound effective value.

Embodiment: the invention will be further described below in conjunction with accompanying drawing;

The mini chord mouth organ of the present invention is made up of qin lattice (3) cover plate screws (9) upper cover plates (1) lower covers (2) in the drawings, it is characterized in that: be provided with double-deck mylar sheet 10 by last grill 4 fronts of two different scales respectively with qin lattice 3, reverse side is provided with 6 times grill 5 fronts of tone reed and is provided with tone reed 7, reverse side is provided with double-deck mylar sheet 10, and on the mylar of nexine, add layer of particles, make its surface galling, be contained in the both sides of qin lattice 3, be welded with on the last grill 4 and the corresponding tone reed 6 of qin lattice 3 hole numbers, the outside that following grill 5 is welded with corresponding tone reed 7, two grills of qin lattice 3 hole numbers is respectively arranged with upper cover plate 1 lower cover 2; One group of tone reed 6 on the last grill 4 vibrates to qin lattice 3 rows of making when air-flow is blown into air from the last row left side, produces music.What at this moment play wind instruments is Major chord; Another group tone reed 6 on the last grill 4 vibrates to qin lattice 3 rows of making when air-flow is blown into air from the last row right side, produces music.At this moment the dominant seventh chord of playing wind instruments; When air-flow makes down one group of tone reed 7 on the following grill 5 of row vibrate from arranging left side suction air down to qin lattice 3, produce music.At this moment the dominant seventh chord of playing wind instruments; When air-flow from arrange down the right side suck air make down to qin lattice 3 row down another group tone reed 7 on the grill 5 vibrate the generation music.At this moment the minor triad of playing wind instruments; Upper cover plate 1 lower cover 2 is marked with mark, can change various modes and tonality arbitrarily according to accompaniment is required.

Claims

1. mini chord mouth organ by the qin lattice, go up grill, down grill, cover plate and cover screw are formed up and down, it is characterized in that: on the mouth organ qin lattice respectively by two different scales on grill, down grill is contained in qin lattice both sides, and by qin lattice screw retention; Grill adopts brass sheet to be stamped to form, the tone reed of the different scales of welding on brass sheet, the grill reverse side is provided with double-deck mylar, on double-deck mylar, added a strata ammonia ethene particulate, make its surface galling, purpose is to leave certain space each other when two-layer mylar is overlapping, the air-flow ratio be easier to by; Outer field mylar is red film, covers on the film of nexine, mainly plays the effect of spring and protection nexine mylar.
