Description

TECHNICAL FIELD

[0001] The utility model relates to the field of musical instruments, in particular to segmented adjustable combination root tone and chord harmonica. BACKGROUND

[0002] The most basic function of the chord harmonica is to emit harmony, which can be used in harmonica accompaniment. The reed configuration is arranged in units of chord components, and each group of harmony is composed of 4-8 reeds. The basic harmonies that can be emitted by the chord harmonica produced by the harmonica factory are major triads, minor triads and dominant seventh chords. Depending on the model, augmented triads and diminished triads can be added. The position of each group of chord components of each model of chord harmonica produced by the harmonica factory is fixed on the whole reed plate according to the usage rate of chord components in the conventional use of the harmonica. It is impossible to meet the different needs of different players. SUMMARY

[0003] In view of the problems in the prior art, the utility model provides a segmented adjustable combination root tone and chord harmonica, each group of chord components is arranged on a sub-reed plate, and multiple sub-reed plates are separately detachably mounted on the harp grid.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0005] The segmented adjustable combination root tone and chord harmonica comprises a harp grid, an upper reed plate, a lower reed plate, an upper cover plate and a lower cover plate. The harp grid is arranged between the upper reed plate and the lower reed plate. The upper cover plate is located above the upper reed plate, and the lower cover plate is located below the lower reed plate. The harp grid, the upper reed plate, the lower reed plate, the upper cover plate and the lower cover plate are assembled into an integral whole. The upper reed plate and the lower reed plate are each segmented into a sub-reed plate according to one group of chord components. Multiple sub-reed plates are arranged and combined according to the blowing requirement and are separately detachably mounted on the harp grid.

[0006] A further improved scheme is that each sub-reed plate is screwed on the harp grid.

[0007] A further improved scheme is that a spring groove comprising two root tones and a spring groove comprising four or five chord component tones are formed on each sub-reed plate.

[0008] A further improved scheme is that the left two spring grooves on the sub-reed plate are root tone spring grooves, and the right spring groove is a chord component tone spring groove. The distance between the root tone spring groove and the adjacent chord component tone spring groove is greater than the distance between other spring grooves. ADVANTAGEOUS EFFECTS

[0009] The original whole spring plate is segmented into multiple sub-spring plates, each of the sub-spring plates comprises a group of chord constituent sounds and root sounds, the multiple sub-spring plates are separately and detachably mounted on the grid, and a player can freely arrange and combine different sub-spring plates according to blowing requirements to DIY and replace the sub-spring plates, so that the segmented and replaceable and combinable root sound and chord harmonica is more suitable for use by different players. BRIEF DESCRIPTION OF DRAWINGS

[0010] Figure 1 It is a structural schematic view of the present application. DETAILED DESCRIPTION

[0011] As Figure 1 shown, the segmented and replaceable and combinable root sound and chord harmonica comprises a grid 1, an upper spring plate, a lower spring plate, an upper cover plate and a lower cover plate (the lower spring plate, the upper cover plate and the lower cover plate are not shown in the figure), the grid is arranged between the upper spring plate and the lower spring plate, the upper cover plate is arranged above the upper spring plate, and the lower cover plate is arranged below the lower spring plate, the grid, the upper spring plate, the lower spring plate, the upper cover plate and the lower cover plate are assembled into an integrated body, the upper spring plate and the lower spring plate are each segmented into a sub-spring plate 2 according to a group of chord constituent sounds, the multiple sub-spring plates 2 are arranged and combined according to blowing requirements, and are separately and detachably mounted on the grid 1, and each of the sub-spring plates 2 is screwed on the grid 1.

[0012] In the figure, each of the sub-spring plates 2 is provided with spring grooves 21 including two root sounds and a group of four or five chord constituent sounds. The left two spring grooves of each of the sub-spring plates 2 are root sound grooves, and the right spring grooves are chord constituent sound grooves, and the distance between the root sound grooves and the adjacent chord constituent sound grooves is greater than the distance between other spring grooves.

[0013] The above is only a preferred embodiment of the present application, and the protection scope of the present application is not limited to the above embodiment, and any technical solution falling within the idea of the present application belongs to the protection scope of the present application. It should be noted that, for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principle of the present application are also considered as the protection scope of the present application.
