Technical Field

The utility model belongs to chromatic scale harmonica musical instrument check field, concretely relates to chromatic scale harmonica musical instrument check subassembly of adjustable timbre.

Background

The chromatic scale harmonica is improved from a traditional harmonica, and a lifting chromatic can be played on one harmonica by utilizing a skillful tone-changing plate key, because the key has a wide range and is convenient for tone shifting or tone changing, the key is rapidly popularized in recent years and is often applied to harmonica ensemble and multiple plays.

The structure of a chromatic harmonica has a great influence on the degree of easy blowing and the timbre of the chromatic harmonica. Particularly, the air duct structure on the musical instrument grid needs to be an inclined plane in order to improve the air guiding degree, but the volume is reduced when the angle of the inclined plane is larger, and the blowing degree is reduced when the angle is smaller. In addition, the size of the wind channel also has an influence on the sound volume and the tone. The volume of the air duct is large, and the volume of the air duct is small.

The existing chromatic scale harmonica has the following defects in the using process:

① the piano lattice produced by the prior art by the injection molding process has inherent defects and can not ensure the ground flatness of the wind groove.

② the existing chromatic scale harmonica lattice is closed as a whole, the lattice is directly contacted with the sounding spring plate, and the sounding spring plate produces resonance, but the tone is single and unchanged, and the tone cannot be adjusted in a personalized and targeted way.

③ the existing chromatic scale harmonica has large volume and heavy weight.

④ the shift push key of existing chromatic harmonica is in direct contact with the case of harmonica, and if it is used for a long time, the assembly is easy to be worn, resulting in poor smoothness and air leakage.
