Description

Technical Field

[0001] This utility model relates to the field of harmonicas, and in particular to a membrane-free, washable, high-quality chromatic harmonica. Background Technology

[0002] The chromatic harmonica is an improvement on the traditional harmonica. Using a clever key, it allows players to play sharps and flats (semitones) on a single instrument. Each hole on the frets allows for four notes to be played simultaneously. Except for a few high notes, each reed is covered with a membrane valve (commonly known as a membrane) to prevent air leakage and ensure airtightness. However, this also presents a problem: during playing, the membrane may stick or slap, affecting sound quality. Additionally, harmonicas with membranes cannot be washed. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a membrane-free, washable, high-quality chromatic harmonica. While removing the film, it divides the air duct of the same frame into sections, and each reed has an independent sound space, ensuring airtightness and improving sound quality. It also eliminates the phenomenon of film sticking and film slapping, and is washable.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A membrane-free, washable, high-quality chromatic harmonica includes a frame, a pitch-changing plate, a mouthpiece plate, an upper spring plate, a lower spring plate, an upper cover plate, and a lower cover plate. The frame is located between the upper and lower spring plates. The upper cover plate is located above the upper spring plate, and the lower cover plate is located below the lower spring plate. The pitch-changing plate is located in front of the frame, and the mouthpiece plate is located in front of the pitch-changing plate. Each mouthpiece of the mouthpiece plate has two spring grooves on the upper and lower spring plates. One side of each spring groove is covered with a reed, and the other side is not covered with a membrane. Vertical partitions are provided in the upper and lower air ducts of the frame corresponding to each mouthpiece, dividing the air duct of the frame corresponding to one mouthpiece into four single holes. Each single hole corresponds to a spring groove position on the reed plate.

[0006] A further improvement is to extend the rearward depth of the partition beyond the corresponding spring groove on the spring plate, ensuring complete independence of the sound produced by each reed.

[0007] A further improvement is that the depth of the partition is consistent with the depth of the air duct. This makes it easier to manufacture.

[0008] A further improvement is that the partition and the main body of the instrument frame are an integral structure, resulting in better airtightness.

[0009] A further improvement is that the partition and the main body of the zither are integrally molded resin or plastic parts.

[0010] Another objective of this invention is to provide an independently partitioned piano grid structure, wherein the piano grid has multiple air ducts in two layers, and each air duct is provided with a vertical partition, dividing the air duct corresponding to each blowhole into four.

[0011] A further improvement is that the partition and the main body of the zither are an integral structure.

[0012] Beneficial effects:

[0013] This application does not directly remove the membrane from the harmonica because it cannot be washed. Instead, it improves the frame structure by designing four separate chambers for blowing and drawing within one air duct. Each reed produces sound independently without affecting the others, ensuring airtightness. The high-quality harmonica without the membrane produced by this application will not experience membrane sticking or slapping when played and can also be washed. Attached Figure Description

[0015] Figure 2 This is a schematic diagram of the three-dimensional structure of the zither rack of this utility model. Detailed Implementation

[0016] like Figure 1 , Figure 2 As shown, this utility model harmonica includes a frame 1, a pitch-changing plate, a mouthpiece, an upper spring plate 2, a lower spring plate 3, an upper cover plate, and a lower cover plate. The frame 1 is located between the upper spring plate 2 and the lower spring plate 3. The upper cover plate is located above the upper spring plate, and the lower cover plate is located below the lower spring plate. The pitch-changing plate is located in front of the frame, and the mouthpiece is located in front of the pitch-changing plate. The pitch-changing plate, mouthpiece, upper cover plate, and lower cover plate, which have not been modified in the figure, are not shown. The frame 1 has multiple air ducts 6 in two layers. Each mouthpiece of the mouthpiece of a conventional chromatic harmonica... Corresponding to the upper and lower air ducts, two spring grooves 4 are respectively opened on the upper and lower spring plates at the position of each blowhole of the blowhole plate. One side of each spring groove is covered with a spring sheet 5, and the other side is covered with a film to ensure sealing. However, in the technical solution of this application, the other side of each spring groove is not covered with a film. The upper and lower air ducts 6 at the position of each blowhole are provided with vertical partitions 7, which divide the air duct of the blowhole into four single holes. Each single hole corresponds to a spring groove position on the spring plate.

[0017] The rearward depth of the partition 7 is consistent with the depth of the duct 6. The partition 7 and the duct 1 body are integrally molded resin or plastic parts, which have better airtightness and are easier to process.

[0018] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
