Description

The chromatic harmonica of inflexion plate pressing fuzz tone

Technical field

The utility model relates to musical instrument fields, more specifically, it relates to a kind of chromatic scale of inflexion plate pressing fuzz tone Mouth organ.

Background technique

Chromatic harmonica is from traditional mouth organ improvement, and using one, cleverly inflexion plate key can be in a mouth organ Lifting semitone is played out above, because its range is wide, and is convenient for transposition or modulation, is promoted rapidly in recent years, is often applied to mouth organ It instrumental ensembles and multiple plays.Chromatic harmonica successively assembles inflexion plate and mouthpiece, specific connection structure such as Fig. 4 in qin lattice front side wall It is shown, it is that card slot is set in mouthpiece back side edge, inflexion plate is interspersed wherein, then mouthpiece is fixed on putting down on front side of qin lattice by screw On mouth.Poor air-tightness between inflexion plate and qin lattice, has gap, can gas leakage dysphonia when causing to play wind instruments；Simultaneously because changing voice Plate and mouthpiece are metalwork, and inflexion plate top, following, three face of front side and mouthpiece all generate metal friction in pressing keys, are produced Raw certain noise, seriously affects sound quality.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide it is a kind of solve the above problems change voice Plate presses the chromatic harmonica of fuzz tone, and setting slot is connect with inflexion plate on qin lattice, and the two air-tightness is good, air tight, plays wind instruments Easily, and reduce inflexion plate and metalwork frictional contact surface, frictional noise is faint, promoted mouth organ play wind instruments sound quality.

To achieve the above object, the utility model provides following technical solution:

Inflexion plate presses the chromatic harmonica of fuzz tone, including is located in the middle Qin Ge, successively assembles above qin lattice upper Spring plate, upper cover plate, lower reed plate that lower section successively assembles, lower cover plate, inflexion plate that front side wall successively assembles, mouthpiece are described to change voice Plate right end protrudes key, and spring part is equipped with inside qin lattice right end, and spring part connects inflexion plate, and pressing keys inflexion plate is in qin lattice The left and right displacement between mouthpiece, the Qin Ge are resin piece or acrylic part, respectively forwardly extend edge below on front side wall Side forms slot, and inflexion plate is interspersed in slot.Inflexion plate and three face contact of qin lattice, air-tightness is good, air tight to play wind instruments easily, and Only front side is contacted with metal mouthpiece, and noise is small, and sound quality greatly promotes.

The utility model is further improved technical solution, respectively forwardly extends L-type on the qin lattice front side wall below Along side.Inflexion plate surrounding does not contact with metal mouthpiece, further promotes sound quality.

The utility model compared with prior art, has the advantage that

The slot of current chromatic harmonica inserting inflexion plate by being arranged on mouthpiece, is changed on qin lattice by the utility model Setting, so that the gap of inflexion plate and qin lattice becomes smaller, air-tightness more preferably, weakens because playing wind instruments difficulty caused by gas leakage；And change Qin lattice sliding contact made of three face metal frictions of former inflexion plate and mouthpiece, metal inflexion plate and resin or acrylic weakens The noise that friction generates, the sound quality that plays wind instruments mouth organ are purer.

Detailed description of the invention

Fig. 1 is chromatic harmonica front view.

The first structure partial schematic diagram of Fig. 2 the utility model；

Fig. 3 is second of structure partial schematic diagram of the utility model；

Fig. 4 is existing chromatic harmonica mouthpiece, inflexion plate and Qin Ge structural schematic diagram.

Specific embodiment

As shown in figure 4, existing chromatic harmonica, the connection structure of mouthpiece, inflexion plate and Qin Ge are, qin lattice front side wall is flat Card slot is arranged in mouthpiece back side edge in face, and inflexion plate is interspersed wherein, and mouthpiece is fixed in the flat mouth on front side of qin lattice by screw. The structure due to above and below the inflexion plate of metal material, three face of front side all connect with the mouthpiece of metal, one with qin lattice poor air-tightness, There is certain gap, the crackjaw status of gas leakage can be generated；Two come inflexion plate and three face metal face contact of mouthpiece, and inflexion plate is sliding When shifting, the grating between metal is big, causes noise larger, sound quality is impure.

As shown in Figure 1 and Figure 2, the utility model includes being located in the middle qin lattice 5, the upper spring plate successively assembled above qin lattice 1, upper cover plate 8, lower reed plate 2 that lower section successively assembles, lower cover plate 9, inflexion plate 6 that front side wall successively assembles, mouthpiece 7, the change 6 right end of soundboard protrudes key 3, and spring part (not shown) is equipped with inside 5 right end of qin lattice, and spring part connects inflexion plate 6, presses Key 3, the left and right displacement between qin lattice 5 and mouthpiece 7 of inflexion plate 6 are pressed, the qin lattice 5 are resin piece or acrylic part, front side Respectively forwardly extend below on wall and form slot 4 along side 51, inflexion plate 6 is interspersed in slot 4.Inflexion plate 6 is upper and lower, rear side Face is directly contacted with qin lattice 5.

In order to contact inflexion plate 6 not completely with mouthpiece 7, as shown in figure 3, on 5 front side wall of qin lattice it is following respectively to Before extend L-type along side 51.

The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
