Abstract

The utility model relates to a harmonica, which is composed of harmonica grids, sound hole boards, an upper cover board, and a lower cover board. The sound hole boards are positioned through recesses, and the recesses are processed on the harmonica grids into trapezoidal structure. Therefore, the utility model has the advantages of cost saving, accurate positioning, simple assembly, and clear sound.

Description

Mouth organ

The utility model relates to a kind of blowing instrument mouth organ.

Common mouth organ is influenced by tradition, and process structure changes little, during manual setting, if the processes precision is not high, causes the assembling difficulty easily, when playing wind instruments, also can cause gas leakage, and hoarseness is not loud and clear, and the music of playing wind instruments lacks unity and coherence, and also is easy to out of tune.

The utility model just provides a kind of can reducing production costs, and is beneficial to the mouth organ of assembling.

The purpose of this utility model is to realize like this, mould at mouth organ and to have the grill locating slot on the lattice, the size of locating slot and the equal and opposite in direction of grill, grill generally all adopts brass to be stamped to form, riveted joint has tone reed on yellow steel plate, past all adopts and moulds the equal-sized rectangle brass sheet of lattice as grill, cause the waste of a lot of brass materials, through process modification, grill is changed into trapezium structure, not only can save the brass material 1/3 of grill, also can correspondingly shorten the length of tone reed, thereby reach the purpose that reduces cost.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the structural representation of mouth organ;

Fig. 2 is the structural representation of qin lattice;

Fig. 3 is the structural representation of grill.

1, qin lattice 2, cover plate 3, last grill 4, following grill

5, rivet 6, last tone reed 7, following tone reed

In Fig. 2, upward the sound hole board slot is processed into trapezium structure at qin lattice (1), corresponding upward grill (3) and following grill (4) strike out trapezoidal shape, consistent with the locating slot that is processed on the qin lattice (1), install grill (3) like this and following grill (4) is just very convenient, accurate positioning, just grill can be fixed with a spot of rivet, and grill will reduce 1/3, save cost greatly, thereby reach the simple purpose of assembling.Owing to adopted at qin lattice (1) and gone up the method that fluting is installed grill, increased the sealing of product, air-flow is not easy to produce and leaks, and can not cause when playing wind instruments hoarseness, out of tune.Thereby can guarantee that the mouth organ pronunciation is accurate, clear, graceful.

Claims

1, mouth organ is made up of qin lattice, grill, last grill, following grill, it is characterized in that: the locating slot that is processed with trapezium structure on the qin lattice of described mouth organ.

2, mouth organ according to claim 1 is characterized in that: described grill be processed into the qin lattice on the equal and opposite in direction grill of shape in echelon.
