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.

Further, the temperature control unit is a temperature control switch.
Further, the temperature control switch controls the temperature to be 15-30 ℃.
Furthermore, the temperature control unit is set as a temperature control chip, the target temperature is fixed to realize accurate temperature control, and the on-off of the power supply of the heating wire is controlled according to the actual temperature of the piano cabinet.
Further, the target temperature is set to 20 ℃. + -. 2 ℃.
Further, the heater strip set up insulating heat-conducting layer outward, insulating heat-conducting layer contact with the musical instrument check, realize the heat transfer.
The heatable chromatic harmonica has the beneficial effects that: set up an electrical interface in musical instrument check lower extreme side, for the inside temperature control unit power supply of musical instrument check, the temperature control unit can adopt two kinds of schemes: firstly, temperature control is carried out by using a temperature control switch, and the actual temperature range is controlled to be 15-30 ℃; secondly, a special temperature control chip is used, the typeC interface is electrified to enter a heating temperature control mode (no additional switch is arranged), the target temperature is fixed to be 20 +/-2 ℃, and the on-off of the power supply of the heating wire is controlled according to the actual temperature of the organ grid, so that accurate temperature control is realized. The defects that the existing piano warming mode is inconvenient to carry and cannot continuously maintain the temperature of the piano body are overcome, and the phenomenon of mucosa cannot be generated, so that the metal piano warming device has a more prominent effect in products using metal piano grids.
