[0021] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0022] Please refer to Figures 1 to 3. The present invention provides a technical solution: a sliding harmonica, comprising a body 1 and guard plates 2 installed on both sides of the body 1, the top of the guard plate 2 is slidably connected to a slide 10, the surface of the slide 10 is plugged with a mouthpiece 12, and the surface of the slide 10 is plugged with a limit plunger 15, and the top surface of the guard plate 2 is provided with multiple limit grooves 7; the lips hold the mouthpiece on the slide, and the slide is moved to play notes; mechanical limits or electronic limits are set between the slide and the frets, so that the player can accurately sense the position of the notes. Embodiment 2

[0023] On the basis of Embodiment 1, in order to achieve the assembly of the body 1 and the guard plate 2, a reserved groove 3 is provided on the surface of the guard plate 2. The reserved grooves 3 on the surfaces of the two guard plates 2 are both oriented towards the body 1. The top surfaces of the guard plate 2 and the body 1 are coplanar. Two groups of through holes 4 are provided on the surfaces of the body 1 and the guard plate 2. The through holes 4 on the surfaces of the body 1 and the guard plate 2 are penetrated by the same set of bolts 5, and a nut 6 is screwed at one end of the bolt 5;

[0024] Lean the two guard plates 2 against both sides of the body 1 respectively. After passing the bolt 5 through the through holes 4 on the surfaces of the body 1 and the guard plate 2, screw the nut 6 onto one end of the bolt 5. After tightening the nut 6, the two guard plates 2 clamp the body 1. Embodiment 3

[0025] Referring to FIGS. 3 to 7, on the basis of Embodiment 2, in order to form a structure for sensing the position of musical notes when the sliding table 10 slides along the guard plate 2; a sliding groove 8 is provided on the top surface of the guard plate 2, and a stop strip 9 is fixed on the surface of the sliding groove 8. The sliding table 10 has a "C" - shaped plate - like structure. Clamping strips are integrally formed on the two parallel side plates of the sliding table 10. The clamping strips are slidably connected between the stop strip 9 and the bottom surface of the sliding groove 8; the jack 11 is centered on the top surface of the sliding table 10, and the mouthpiece 12 is inserted into the jack 11. Sound - insulating cotton 13 is provided on the bottom surface of the top plate of the sliding table 10. The sound - insulating cotton 13 is located between the top surfaces of the sliding table 10 and the body 1, and a reserved opening is provided on the surface of the sound - insulating cotton 13, and the reserved opening corresponds to the jack 11; the limiting groove 7 is an inverted isosceles trapezoidal groove. An embedding hole 14 is provided on the top plate of the sliding table 10. The limiting plunger 15 passes through the embedding hole 14 and the sound - insulating cotton 13 and then is inserted into the limiting groove 7.

[0026] Push the sliding table 10 into the guard plate 2 from one end. The clamping strips of the sliding table 10 slide into the groove between the sliding groove 8 and the bottom surface of the stop strip 9. During the sliding process of the sliding table 10, the limiting plunger 15 falls into the limiting groove 7 due to gravity. When the sliding table 10 slides, the limiting plunger 15 slides out along the inclined surface of the limiting groove 7. When the sliding table 10 moves to the next limiting groove 7, the limiting plunger 15 falls into the limiting groove 7 again to achieve the sensing of musical notes.

[0027] During actual use, the two guard plates 2 are respectively placed on both sides of the piano body 1, and after the bolt 5 is passed through the through-holes 4 on the surface of the piano body 1 and the guard plate 2, the nut 6 is screwed on one end of the bolt 5. After the nut 6 is tightened, the two guard plates 2 clamp the piano body 1; the slide 10 is pushed in from one end of the guard plate 2, and the card bar of the slide 10 slides into the groove body between the slide groove 8 and the bottom surface of the baffle bar 9. During the sliding process of the slide 10, the limit plunger 15 falls into the limit groove 7 due to gravity. When the slide 10 slides, the limit plunger 15 slides out along the inclined surface of the limit groove 7. When the slide 10 moves to the next limit groove 7, the limit plunger 15 falls into the limit groove 7 again, realizing the perception of the notes.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
