Technical Field

The invention relates to the technical field of harmonicas, in particular to a heatable chromatic scale harmonica.

Background

The scale tissue of a chromatic scale harmonica is like a piano, and besides ordinary tones, chromatic scales which are not possessed by the ordinary harmonica are added. The chromatic scale harmonica is mainly divided into four types, namely ten holes, twelve holes, fourteen holes and sixteen holes. The chromatic scale harmonica is rapidly popularized in recent years, is wide in range and convenient to move or change tones, and is frequently applied to harmonica ensemble and multiple playing, wherein the chromatic scale harmonica with twelve holes is most used.

Before playing the harmonica, the harmonica is easy to maintain and clean in normal times, but the temperature is low in winter, and the harmonica is sticky and called as a mucous membrane. In the environment with lower temperature, when the blowing gas passes through the cold copper spring plate, water vapor can be condensed, and the mucosa phenomenon can inevitably occur occasionally, so that the mute or the crackle are caused, and the actual annoyance is caused. Some lyre friends always have some inconveniences when using a hand warmer hot water bag and the like, and the lyre friends are heated by electric air blowing, but the diaphragm is warped and deformed in the process of heating.
