Abstract

The utility model relates to a harmonica, which consists of a cover plate, blowing holes, grids, sound hole plates, and screws of the blowing holes, wherein a sound changing plate is arranged between a sound changing bottom plate and the blowing hole plates, and a press-down key is arranged on one end of the sound changing plate. When in use, the harmonica can generate 56 kinds of different pitches from the 14 blowing holes by controlling the sound changing plate at different positions, thereby greatly improving the applicability of the harmonica. The 14-hole 56-pitch harmonica has the advantages of simple structure, convenient operation and use, and high practicability.

Description

14 holes, 56 sound mouth organs

Technical field:

The utility model relates to a kind of chromatic harmonica, particularly relates to a kind of scale arrangement and C phase modulation together, 14 holes, the 56 sound mouth organs that range is made up of bass, middle pitch, high pitch.

Technical background:

At present, the mouth organ of producing on the market is tremolo harmonica, and playing wind instruments highly difficult song has certain degree of difficulty, when playing wind instruments, gas leakage is difficult to correctly blow out tone easily, on a mouth organ, can not play out bass, middle pitch, high pitch simultaneously, bring a lot of inconvenience to the bassoonist.

Summary of the invention:

The purpose of this utility model will provide a kind of 14 holes 56 sound mouth organs exactly, it can overcome the problem that above tremolo harmonica exists well, the purpose of this utility model is to realize like this, 14 holes, 56 sound mouth organs are by cover plate, mouthpiece, Qin Ge, grill, the mouthpiece screw is formed, it is characterized in that: at Qin Ge and blow and be provided with two-layer base plate between the orifice plate, the inside and qin lattice near be the base plate of changing voice, be provided with the hole of blowing above with the identical number of qin checkerwork cell, changing voice base plate and blow and be provided with inflexion plate between the orifice plate, one end of inflexion plate is provided with presses key, on the inflexion plate upper punch has, following at interval square hole and blows the same half of qin checkerwork cell of being in hole; Be provided with tone reed below the described grill, reverse side is provided with double-deck mylar sheet, and on the mylar of nexine, adds layer of particles, makes its surface galling.The utility model can play out high, medium and low sound simultaneously on a mouth organ, and the music of range broadness, and scale is two rows, and the inflexion plate original position is that C transfers whole tone scale, and the propelling inflexion plate is C ^#Whole tone scale, scale is arranged identical with piano, has the function that each masterpiece in music of the world is played wind instruments in any modified tone.

Embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

In the drawings, the utility model 14 holes 56 sound mouth organs are made up of cover plate 1, mouthpiece 8, qin lattice 2, grill 3, mouthpiece screw 7, it is characterized in that: at qin lattice 2 and blow and be provided with two-layer base plate between the orifice plate, the inside and qin lattice 2 near be the base plate of changing voice, be provided with the hole of blowing above with the identical number in qin lattice 2 holes, changing voice base plate and blow and be provided with inflexion plate 11 between the orifice plate, one end of inflexion plate 11 is provided with presses key 10, inflexion plate 11 upper punches have upper and lower interval square hole, and blow the same half of qin lattice 2 holes of being in hole; Described grill 3 fronts are provided with tone reed 4, and reverse side is provided with double-deck mylar sheet 5, and on the mylar of nexine, add layer of particles, make its surface galling.During concrete enforcement,, tone reed is processed into than traditional reed length of a film, can produces simple and honest bass like this in the tone reed baritone district of grill 3.At treble, tone reed is processed into than traditional tone reed weak point, just can play out than higher scale.In grill 3 fronts tone reed 4 is housed, reverse side just is provided with double-deck mylar sheet 5, on the mylar of nexine, carry out chemical treatment, add a strata ammonia ethene particulate, make its surface galling, outer field mylar is red film, cover on the nexine film, the hole of blowing of mouth organ changes circular configuration into, be provided with two-layer base plate at qin lattice 2 between the orifice plate with blowing, the inside and qin lattice 2 near be the base plate of changing voice, be provided with the hole of blowing above with the identical number in qin lattice 2 holes, at inflexion plate and blow and be provided with inflexion plate 11 between the orifice plate, inflexion plate 11 1 ends are provided with presses key 10, and key 10 positions are pressed in conversion, can make inflexion plate 11 and blow between the orifice plate to slidably reciprocate, on inflexion plate 11 upper punches have, following at interval square hole, and with inflexion plate loam cake 9 blow the same half of qin lattice 2 holes of being in hole.When pressing key 10 in the A position, air-flow is blown into through mouthpiece 8 from inflexion plate loam cake 9, enters (row's mouth is covered by inflexion plate down) inflexion plate lower cover 12 through inflexion plate 11 from upper outlet and flows into qin lattice 2, and the tone reed 4 on the row's of making grill 3 vibrates, and produces music.This moment, the tone reed 4 at grill 3 back sides was covered by diaphragm 5, and air-flow can not pass through.When air-flow sucks air from inflexion plate loam cake 9 through mouthpiece 8, air-flow flows into from tone reed 4, drives tone reed 4 vibrations, produces music.And the tone reed 4 at grill 3 back sides is covered by diaphragm 5 at this moment, and air-flow can not pass through.Thereby when pressing key in the A position, the upper outlet of qin lattice 2 has two kinds of pronunciations.Because grill 3 of the present utility model is two-sided designs, when press key 10 press into, just press key 10 when the B position, because moving of inflexion plate 11, air-flow is blown into through mouthpiece 8 from inflexion plate loam cake 9, enter (this moment, upper outlet can be covered by inflexion plate owing to inflexion plate moves) inflexion plate lower cover 12 inflow qin lattice 2 from arranging mouth down through inflexion plate 11, make down tone reed 4 pronunciations of arranging on the grill 3.When air-breathing, make down adjacent tone reed 4 pronunciations on row's grill 3 equally.The following row mouth of qin lattice 2 also has two kinds of pronunciations, like this from inflexion plate loam cake 9 on mouthpiece 8, by lifting the conversion of key 10A, B position, 14 are blown the hole, can send 56 kinds of different tones, have improved the applicability of mouth organ greatly.The inflexion plate lower cover 12 that in qin lattice 2 and inflexion plate loam cake 9, adds; its effect is to have improved the sealing of qin lattice 2 with inflexion plate loam cake 9; because inflexion plate lower cover 12 smooth surfaces; when inflexion plate 11 moves; can reduce resistance; reduce coefficient of friction each other simultaneously; the double-deck mylar 5 that on grill 3, is provided with; the nexine surface galling; purpose is when two-layer mylar is overlapping; leave certain space each other, the air-flow ratio is easier to mainly play spring action and protection nexine mylar by, outer red film.
