Description
Technical Field
The utility model relates to an harmonica with gas storage function. Belongs to the technical field of musical instruments.
Background
Harmonica (english: Melodica) is a keyboard type playing instrument with small volume, good intonation and excellent rhythmicity, and belongs to a free reed playing instrument in the same category of instruments as harmonica.
The harmonica uses a pianized keyboard, and the reed is driven to produce sound by blowing through the side blowing nozzle, so the harmonica can also be regarded as a blowing type keyboard instrument. The range of the harmonica is about three octaves, and rich harmony effects can be played. In addition, the music box has good harmony capability and a wide range of sound range, and is widely applied to various kinds of music.
The air flow channel of the existing harmonica is of a straight-through type (one end is in and the other end is out), when a performer plays the harmonica, the performer needs to exchange air frequently, obviously, compared with the two stages of air blowing and air suction, the pressure in the air flow channel in the air blowing stage is larger than the pressure in the air flow channel in the air suction stage. Because the pressure in the air flow channel is unbalanced when the performer plays, even no air flow exists during ventilation, and no pressure exists in the air flow channel, the sound volume and the tone of the organ played by the mouth organ are inconsistent, and the playing quality is influenced.
