Description

Technical Field

[0001] The present invention relates to the technical field of harmonica manufacturing, and relates to a single-row 36-hole full-range harmonica having a chromatic alternating arrangement structure.

Background Art

[0002] Conventional harmonicas have the following drawbacks.

[0003] 1. Fixed mode: Since the modes of single-row multiple-hole harmonicas and polyphonic harmonicas are fixed, when modulation or key change is required during performance, complex pieces can only be played by combining harmonicas of different modes. 2. Complexity of chromatic operation: Chromatic harmonicas (e.g., Hohner Chromonica) need to switch chromatic tones with side slide buttons, which impairs the continuity of performance. 3. Disorder of scale arrangement: The high and low arrangement distribution of scales is disordered, and the performance logic is not clear. The following are three common examples. 1. Polyphonic harmonica - 24-hole general solo arrangement

Summary of the Invention

[0004] Based on the above background, the present invention provides a single-row 36-hole full-range harmonica having a chromatic alternating arrangement structure.

[0005] The technical means provided by the present invention are as follows.

[0006] A single-row, 36-hole, full-range harmonica having a chromatic alternating arrangement structure including a comb, wherein a cover plate is provided on one side of the comb, and a sealing plate is provided on the side of the comb opposite to the cover plate. The comb has 36 tone holes, the tone holes are arranged in a single row, and partition plates are provided between the tone holes. A single-row, 36-hole, full-range harmonica having a reed plate between the lid and the comb, with reed holes provided on the reed plate corresponding to each tone hole, and blowing reeds and drawing reeds provided at positions corresponding to the reed holes on the reed plate, with the blowing reeds and drawing reeds arranged alternately, forming a chromatic alternating arrangement structure.

[0007] Preferably, the pitch difference between adjacent inhaling and blowing reeds is a semitone, and the pitches rise sequentially from left to right.

[0008] Preferably, the thickness of the blowing reed is 0.08 to 0.12 mm, and the thickness of the draw reed is 0.08 to 0.12 mm.

[0009] Preferably, the suction reed and blowing reed are made of phosphor bronze.

[0010] Preferably, the pitch length between the tone holes is ≤5 mm.

[0011] Preferably, the length of the comb from left to right is ≤ 21 cm.

[0012] Preferably, the thickness of the partition plate is 0.8 to 1 mm.

[0013] By employing the above technical measures, the following beneficial effects can be obtained. 1. Alternating chromatic arrangement: The 36 tone holes in a single row and the blow / draw reeds arrange the chromatic tones alternately, causing the pitch to rise sequentially and covering three octaves (C-B2). 2. Buttonless Design: By the blowing / sucking direction and position, it directly triggers the semitone of adjacent holes or the whole tone of every other hole, simplifying the complexity of performance. 3. The 36 sound holes of the present invention cover 36 semitones. The pitch difference between adjacent sound holes is a semitone, and the pitch difference between every other sound hole is a whole tone. The pitch increases sequentially, allowing for arbitrary key transposition and simplifying the complexity of performance. By covering 3 octaves (C - B2), it can achieve the full range without buttons, meeting the demand for the common pitch range of the 88 keys of a piano and conforming to the performance needs of classical and popular music. At the same time, since the scales are arranged from low to high, the performance logic is clearer and easier to learn. It also conforms to ergonomics. The total length of 36 single-row sound holes is ≤ 21 cm, and the pitch of a single sound hole is ≤ 5 mm, fitting the width of an adult's lips.

[0016] In order to more clearly illustrate the object, technical means and advantages of the embodiments of the present invention, hereinafter, while referring to the drawings in the embodiments of the present invention, the technical means in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative labor all belong to the protection scope of the present invention.

[0019] The present invention will be further described below while referring to the drawings.

[0020] Note that the left and right orientations in the following embodiments are as shown by the arrows in FIG. 7.

[0021] Example 1: The single-row, full-range harmonica shown in Figures 1 to 7 includes a harmonica body with a comb 1, a cover plate 2 provided on one side of the comb 1, and a sealing plate 3 provided on the side of the comb 1 opposite the cover plate. Specifically, the cover plate is detachably attached to the comb by bolts.

[0022] The comb 1 has 36 tone holes 5, which are arranged in a single row, and partition plates 8 are provided between the tone holes 5.

[0023] A reed plate 4 is provided between the lid plate and the comb, and each reed hole is provided on the reed plate 4 corresponding to the tone hole, and blow reeds 6 and draw reeds 7 are provided at positions on the reed plate 4 corresponding to the reed holes, and the blow reeds 6 and draw reeds 7 are arranged alternately.

[0024] Specifically, with the exception of the leftmost and rightmost tone holes, the other tone holes are formed by being surrounded by the reed plate, cover plate, partition plate, and the bottom plate of the comb. The leftmost or rightmost tone hole is formed by being surrounded by the reed plate, cover plate, partition plate, sealing plate, the bottom plate of the comb, and the left or right inner wall of the comb. Each of the aforementioned tone holes has an independent, non-communicating air chamber.

[0025] The pitch difference between adjacent inhaling and blowing reeds is a semitone, and the pitch rises sequentially from left to right.

[0026] The thickness of the blowing reed 6 is 0.08 to 0.12 mm, and the thickness of the drawing reed 7 is 0.08 to 0.12 mm. The difference in thickness gradient and the semitone frequency ratio is 2^{1 / 12}, and the pitch is achieved at a vibration frequency that matches the length and thickness of the reed plate (piano c-b2).

[0027] The aforementioned draw reed and blow reed are made of phosphor bronze.

[0028] The pitch length between the tone holes is ≤5 mm. The length of the comb from side to side is ≤21 cm, which is suitable for an adult lip width of 8-12 mm.

[0029] The thickness of the partition plate 8 is 0.8 to 1 mm.

[0030] In one embodiment of the present invention, the comb 1 and the sealing plate 3 are integrally injection molded from ABS resin. Alternatively, the following embodiment is adopted. As shown in Figure 5, the sealing plate 3 includes a lower cover plate 9 and a lower lead plate 10, the lower lead plate being a flat plate without lead holes, and positioned between the comb and the lower cover plate 9, and the lower lead plate 10 and the lower cover plate 9 are attached to the comb by bolts.

[0031] The scale arrangement and scale of the present invention are as shown in Figures 7 and 8. Figure 7 shows the arrangement of tone holes facing the mouth when in use, with the tone holes arranged from left to right in the order of blow hole, inhalation hole, blow hole, inhalation hole... blow hole, inhalation hole, that is, blow holes and inhalation holes are provided alternately.

[0032] Although the present invention and its embodiments have been described above, this description is not limiting, and the drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, any structural configuration and example similar to the said technical means, designed by a person skilled in the art based on its suggestions, without departing from the spirit of the invention and without creativity, should all fall within the scope of the protection of the present invention.
