Description

Technical Field

[0001] The invention relates to the field of harmonicas, and in particular to a membrane-free, washable, high-quality chromatic harmonica. Background Art

[0002] The chromatic harmonica is an improvement of the traditional harmonica. With a clever key, you can play semitones on a harmonica. Each hole of the fret has four sounds of blowing and sucking at the same time. Except for several sounds in the treble part, each reed is covered with a film valve (commonly known as film) to prevent air leakage and ensure air tightness. But the problem is that the membrane may suddenly stick or hit during playing, affecting the sound quality. At the same time, the harmonica with film cannot be washed. Summary of the invention

[0003] In view of the problems existing in the prior art, the present invention provides a membrane-free, washable, high-quality chromatic harmonica. While removing the film, the air duct of the same fret is divided into zones, and each reed has an independent sounding space to ensure air tightness and improve sound quality, remove the sticky membrane and film-beating phenomenon, and can also be washed.

[0004] To achieve the above object, the present invention provides the following technical solutions: The invention discloses a non-film washable high-quality chromatic harmonica, comprising a fret, a tone change plate, a mouthpiece plate, an upper spring plate, a lower spring plate, an upper cover plate and a lower cover plate, wherein the fret is arranged between the upper spring plate and the lower spring plate, the upper cover plate is located above the upper spring plate, the lower cover plate is located below the lower spring plate, the tone change plate is located at the front side of the fret, and the mouthpiece plate is located at the front side of the tone change plate, two reed grooves are respectively arranged on the upper spring plate and the lower spring plate at a position corresponding to each mouthpiece of the mouthpiece plate, one side surface of each reed groove is covered with a reed sheet, and the other side surface of the reed groove is not covered with a film, and vertical partitions are arranged in the upper and lower air ducts of the fret corresponding to each mouthpiece, so that the fret air duct corresponding to one mouthpiece is divided into four single holes, and each single hole corresponds to a reed groove position on the reed plate.

[0005] A further improvement is that the depth of the partition to the rear exceeds the position of the spring groove on the corresponding spring plate, so as to ensure the complete independence of the pronunciation of each reed.

[0006] A further improvement is that the depth of the partition is consistent with the depth of the piano grid air duct, which is easy to process.

[0007] A further improvement is that the partition and the piano frame body are an integrated structure, which has better airtightness.

[0008] A further improvement is that the partition and the piano frame body are an integrally formed resin or plastic part.

[0009] Another object of the present invention is to provide an independently partitioned piano frame structure, wherein the piano frame has a plurality of air ducts in two layers, each of which is provided with a vertical partition, so as to divide the air duct corresponding to each mouthpiece into four.

[0010] A further improvement is that the partition and the piano frame body are an integral structure.

[0011] Beneficial effects: The present application does not directly remove the adhesive film of the harmonica that cannot be washed. Instead, the structure of the harmonica frame is improved, and four blowing and sound-absorbing chambers are designed in one air duct. The pronunciation of each reed is independent and does not affect each other, ensuring air tightness. The harmonica without adhesive film has high sound quality and will not have sticky membrane or film-slapping phenomena when playing, and can also be washed. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a three-dimensional structural diagram of the assembly of the piano frame and the spring plate of the present invention; Figure 2 It is a schematic diagram of the three-dimensional structure of the piano frame of the present invention. DETAILED DESCRIPTION

[0013] like Figure 1 , Figure 2 As shown in the figure, the harmonica of the present invention comprises a fret 1, a tone changing plate, a mouthpiece, an upper spring plate 2, a lower spring plate 3, an upper cover plate and a lower cover plate. The fret 1 is arranged between the upper spring plate 2 and the lower spring plate 3, the upper cover plate is located above the upper spring plate, the lower cover plate is located below the lower spring plate, the tone changing plate is located at the front side of the fret, and the mouthpiece is located at the front side of the tone changing plate. The tone changing plate, the mouthpiece, the upper cover plate and the lower cover plate that have not been changed in the figure are not shown. The fret 1 has a plurality of air ducts 6 in two upper and lower layers. Each mouthpiece of the mouthpiece of the conventional chromatic harmonica is opposite to the air duct 6. There should be two upper and lower air ducts, and two spring grooves 4 are respectively provided on the upper spring plate and the lower spring plate at the corresponding position of each blowing port of the blowing plate. One side surface of each spring groove is covered with a reed 5, and the other side surface is covered with a film to ensure sealing. However, in the technical solution of the present application, the other side surface of each spring groove is not covered with a film, and vertical partitions 7 are provided in the upper and lower air ducts 6 of the piano grid at the corresponding position of each blowing port, which divides the piano grid air duct corresponding to a blowing port into four single holes, and each single hole corresponds to a spring groove position on the spring plate.

[0014] The depth of the partition 7 to the rear is consistent with the depth of the piano grid air duct 6. The partition 7 and the piano grid 1 body are an integrally formed resin or plastic part, which has better air tightness and is easy to process.

[0015] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
