Fig. 1 is a schematic structural view of a sound box 010 in the embodiment of the present invention; fig. 2 is another angular view of fig. 1. Referring to fig. 1 (see fig. 2 in a matching manner), the sound box 010 of the present embodiment includes a base 400, a rotation driving device 300, a sound tube 100, and a sound comb 200. The rotary driving device 300, the sound cylinder 100 and the sound comb 200 are all mounted on the base 400, and the rotary driving device 300 is used for driving the sound cylinder 100 to move, so that the sound cylinder 100 stirs the comb teeth 210 of the sound comb 200 to generate sound. Optionally, two opposite mounting seats 500 are provided on the base 400, and the sound tube 100 is supported and connected between the two mounting seats 500. The sound comb 200 is connected to the base 400 by the seating member 600 such that the axes of the sound comb 200 and the sound tube 100 are the same height.

Fig. 3 is a schematic structural diagram of the sound tube 100 provided by the present invention; fig. 4 is a cross-sectional view taken along line B-B of fig. 3, which together show the structure of the sound tube 100 in the present embodiment. Referring to fig. 3, the sound tube 100 of the present embodiment includes an outer tube 10 and an inner tube 20. The outer cylinder 10 is sleeved outside the inner cylinder 20 and is configured to be rotatable relative to the inner cylinder 20. The outer peripheral surface P1 of the inner cylinder 20 has spiral teeth 21. A plurality of pinions 30 are rotatably attached to the peripheral wall of the outer cylinder 10 (the "small" of the pinions 30 described in the present application means that the size thereof is small relative to the outer cylinder 10). The pinion 30 penetrates the inner circumferential surface P2 and the outer circumferential surface P1 of the outer cylinder 10. The pinion 30 is configured to mesh with the helical teeth 21 of the inner cylinder 20 and can be rotated by the helical teeth 21 while being rotated with the outer cylinder 10 relative to the inner cylinder 20. Alternatively, the axis of the pinion 30 in the present embodiment is perpendicular to the axis of the spiral teeth 21, the axis of the spiral teeth 21 coincides with the axis of the inner cylinder 20, part of the teeth of the pinion 30 are engaged with the spiral teeth 21 inside the inner circumferential surface P2 of the outer cylinder 10, and part of the teeth of the pinion 30 are exposed outside the outer circumferential surface P1 of the outer cylinder 10, so as to dial the tone comb 200 to generate sound (see fig. 5 for cooperation).

Referring to fig. 1, two ends of the inner cylinder 20 are respectively and fixedly connected to corresponding mounting seats 500, the outer cylinder 10 is rotatably fitted to the mounting seats 500, and the rotary driving device 300 is in transmission connection with the outer cylinder 10 and can drive the outer cylinder 10 to rotate relative to the inner cylinder 20. The rotary driving device 300 in this embodiment may be a hand-operated driving structure, a clockwork driving structure, a motor driving structure, or any other suitable rotary driving structure.

In this embodiment, the rotation of the outer cylinder 10 relative to the inner cylinder 20 can make the pinions 30 located at different generatrices of the outer peripheral surface P1 of the outer cylinder 10 function, for example, to face the sound comb 200, and to move the comb teeth 210 to produce sound; and when the outer cylinder 10 rotates relative to the inner cylinder 20, the pinion 30 thereon can rotate under the driving of the helical teeth 21 of the inner cylinder 20, and the rotation of the pinion 30 can enable different teeth of the pinion 30 to correspond to and be used for shifting the comb teeth 210 to generate sound, because the pinion 30 has a plurality of teeth, different teeth can obtain different sound generating effects through different properties (such as materials and mechanical properties) of the teeth, or sound generation can be realized when different teeth of one pinion 30 pass through the comb teeth 210 through different shapes and sizes (such as lengths) of the teeth. Therefore, compared with the existing scheme of fixing the sound nail on the outer cylinder 10, the type of sound production is greatly improved.

In this embodiment, optionally, the teeth of the pinion 30 have at least two different lengths and/or the teeth of the pinion 30 are constructed of a material that is easily sandable. The length of the teeth of the pinion 30 determines whether the teeth can touch the comb teeth 210, and for the teeth with short length, when the teeth pass through the corresponding comb teeth 210, the teeth do not poke the comb teeth 210, so that the phenomenon does not occur; while longer length teeth will toggle the comb teeth 210 as they pass. Therefore, by controlling the tooth length of each tooth of the pinion 30, a desired beat or a complete music can be obtained as desired. The teeth of the pinion 30 are made of an easily sandable material, so that the user can polish the teeth of the pinion 30 into a desired length and shape according to his or her own needs, thereby achieving a function of inputting music into the sound tube 100, and the user can complete the final manufacturing process of the sound box 010, thereby improving participation. Referring collectively to fig. 5, alternatively, one revolution of the inner barrel 20 corresponds to one revolution of the helical teeth 21 and one revolution of the pinion 30. One set of teeth of the pinion 30 includes 1-5 teeth. Taking an example that one tooth group comprises 2 teeth, when the inner barrel 20 rotates for the first circle, the pinion 30 correspondingly shifts the comb teeth 210 with two adjacent teeth; the inner cylinder 20 rotates for one circle again, and the pinion 30 rotates two teeth, so that another group of two adjacent teeth correspondingly stir the comb teeth 210; by analogy, for example, when the number of the pinions 30 is 12, each pinion 30 has 12/2-6 middle-tooth-shifting state, that is, the outer cylinder 10 rotates for 6 cycles to form one cycle, so that the number of beats corresponding to the sound cylinder 100 is greatly increased, that is, a longer music can be stored or a plurality of music can be realized on one sound box 010.

The following describes an alternative way of distributing the pinion 30 on the outer cylinder 10 and the way of connecting the pinion 30 to the outer cylinder 10.

In this embodiment, one side of the pinion 30 is engaged with the spiral teeth 21, and the other side is used for corresponding to and toggling the sound comb 200, so that a through passage for allowing the pinion 30 is required to be provided on the outer cylinder 10. Referring to fig. 4 and 5, in an embodiment of the present embodiment, a plurality of axial grooves C1 are formed on the circumferential wall of the outer cylinder 10 and extend along the axial direction, and the axial grooves C1 penetrate through the inner circumferential surface P2 and the outer circumferential surface P1 of the outer cylinder 10. Each of the axial grooves C1 is formed to sequentially rotatably engage a plurality of pinions 30 along the longitudinal direction thereof. A row of pinions 30 may be provided in each axial slot C1, arranged sequentially along the length of the axial slot C1, or a plurality of rows of pinions 30 may be provided in each axial slot C1, arranged sequentially along the length of the axial slot C1. The multiple rows of pinions 30 are distributed along the axial direction of the pinions 30, and each row of pinions 30 is staggered along the length direction of the axial groove C1, and when viewed along the axial direction of the pinions 30, adjacent pinions 30 in different rows in the same axial groove C1 have overlapping portions, so that more pinions 30 are arranged within the length range of the axial groove C1, the comb teeth 210 of the sonic comb 200 can be designed to be compact enough, the space is saved, and more notes can be realized by using the outer cylinder 10 and the comb teeth 210 with smaller sizes. The pinions 30 are shown in two rows in fig. 3.

To facilitate the fixing of the pinions 30, referring to fig. 4 and 6, a plurality of annular grooves C2 are further provided on the outer circumferential surface P1 of the outer cylinder 10 and are distributed in the axial direction of the outer cylinder 10. The annular groove C2 is provided in the circumferential direction of the outer cylinder 10, and the depth of the annular groove C2 is smaller than the wall thickness of the outer cylinder 10, i.e., the annular groove C2 does not penetrate the inner surface of the outer cylinder 10. The rotation shaft of the pinion 30 is rotatably fitted to the rotation seats 11 which are fixed in the annular groove C2 and located at both sides in the axial direction of the pinion 30. The rotating seat 11 may be formed in various manners, for example, the annular groove C2 of a whole circle is firstly processed, then both ends of the gear shaft of the pinion 30 inserted into the annular groove C2 are soldered in the annular groove C2 and wrap the gear shaft 31 of the pinion 30, and the pinion 30 can rotate around its own gear shaft 31, so that the fixed installation of the pinion 30 is realized, and the pinion 30 is prevented from falling out. It should be noted that the outer cylinder 10 shown in fig. 4 shows only 6 pinions 30 in a ring shape, and does not mean a limitation on the number of pinions 30, because in actual use, a larger number of pinions 30 are generally provided in a ring shape to increase the number of notes.

In summary, in the embodiment of the present invention, the tooth of the pinion 30 replaces the existing sound nail fixed to the outer cylinder 10 to realize the addition of the toggle structure for the toggle teeth 210, so that the toggle structure with a larger number is provided, the total playing time can be increased, and a longer single song or a more music can be played.

In an optional scheme, a user can manually polish the teeth of the pinion 30, and even edit the music according to personal preference and music requirements, so that the exclusive sound box 010 with the personalized music is manufactured, and the participation and the initiative of the user are improved. In addition, the structure of the scheme enables the parts to be manufactured, only unified parts are required to be manufactured according to the drawing size, and the parts are assembled and molded without time-consuming and labor-consuming adjustment of each tone nail by professional sound mixers, so that the labor cost is reduced, the technical difficulty is reduced, each person can participate in the manufacturing of the sound box 010, the participation degree of a user is improved, and the recognition degree of the user can be improved.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
