[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present invention, it should be noted that the terms "vertical direction", "upper", "lower", "horizontal" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0029] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 3-4 As shown, the resonance box 100 of the utility model is provided; it specifically comprises a front panel 11, a back panel 12 and a side panel 13 connected between the front panel 11 and the back panel 12; the inner sides of the front panel 11, the back panel 12 and the side panel 13 form a resonance cavity 14; the front panel 11 and the back panel 12 are of the same size and are both circular, and the side panel 13 is annular; the cross-sectional shape of the side panel 13 is an arc that is arched outward, and during the performance, the sound will be reflected when it encounters the side panel 13, and the side panel 13 is set to be in an arc shape, which can adjust the reflection direction of the sound and thus adjust the timbre; a sound outlet hole 17 connected to the resonance cavity 14 is provided on the front panel 11.

[0031] Specifically, in this embodiment, the side panel 13 includes a first side panel 131 and a second side panel 132 connected end to end, and the lengths of the first side panel 131 and the second side panel 132 are consistent. In actual production and processing, the first side panel 131 and the second side panel 132 with the same length and cross-sectional curvature are selected, and the first side panel 131 and the second side panel 132 are hot-bent so that the first side panel 131 and the second side panel 132 are in a semicircular arc shape, and the first side panel 131 and the second side panel 132 are connected end to end by gluing or docking to form the side panel 13. In this embodiment, two plates are selected to form the side panel 13; it is understandable that in the actual production of the resonance box 100, one, three, or four plates can be selected to form the side panel 13 according to the material thickness of the plate.

[0032] Specifically, in this embodiment, the thickness of the side plate 13 is 2-5 mm; Figure 3 As shown, the cross section of the side plate 13 forms an arc, and the central angle of the arc (ie, angle A in the figure) is 22-25°; meanwhile, the curvature of the arc is 200-500 degrees.

[0033] Specifically, a plurality of support columns 15 are provided on the inner side of the resonance chamber 14, the upper ends of the support columns 15 are connected to the panel 11, the lower ends of the support columns 15 are connected to the back panel 12, and the outward ends of the support columns 15 are connected to the inner walls of the side panels 13. The support columns 15 play a supporting role to improve the structural strength of the resonance box 100.

[0034] Specifically, the support columns 15 are distributed in a circular array on the inner side of the resonance chamber 14 , so that the supporting force of the support columns 15 is evenly distributed; in this embodiment, 14 support columns 15 are specifically used to ensure the structural strength of the resonance box 100 .

[0035] Specifically, edge strips 16 are provided at the edges of the front panel 11 and the back panel 12. The edge strips 16 are used to connect the front panel 11 and the side panels 13, and the edge strips 16 are used to connect the back panel 12 and the side panels 13. The edge strips 16 are made of wood or rubber and play a role of edging.

[0036] Specifically, the cross-sectional shape of the sound outlet hole 17 is a rectangle.

[0037] like Figure 1 to Figure 2 As shown, the Zhongruan of the present invention includes the above-mentioned resonance box 100, a neck 200 connected to one end of the resonance box 100, a head 300 connected to the end of the neck 200 away from the resonance box 100, a bridge 400 fixed on the panel 11, and strings 500 connected between the head 300 and the bridge 400. A perforation is provided on the bridge 400, wherein the sound outlet hole 17 is aligned with the perforation. When the Zhongruan is used for playing, when the strings 500 are plucked, the resonance box 100 has different sound reflection directions, thereby achieving a better timbre.

[0038] Compared with the prior art, the resonance box 100 and the Zhongruan involved in the utility model, the resonance box 100 includes a panel 11, a bottom plate and a side plate 13, wherein the cross-sectional shape of the side plate 13 is an arc that is arched outward, and the arc-shaped structure of the side plate 13 can change the sound reflection in the resonance box 100, thereby achieving the purpose of adjusting the timbre of the Zhongruan; using the Zhongruan for performance has rich expressiveness; in addition, the sound outlet 17 of the Zhongruan is arranged on the panel 11, specifically, under the bridge 400, to keep the appearance of the Zhongruan neat.

[0039] The above only expresses the preferred technical solution of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
