Background Art

[0002] Traditional xishui drums, known for their unique timbre and sound effects, have established a niche in the musical instrument market. However, their internal structure often restricts the fluidity of the gravel, which in turn affects the diversity of the sound and the durability of the resonance. Furthermore, the corrugated paper structure surrounding the traditional xishui drum increases unnecessary material costs and limits the fluidity and friction of the gravel inside.

[0003] Therefore, designing a new type of stream drum seems particularly important. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0023] Furthermore, the use of terms such as "horizontal," "vertical," and "overhanging" does not necessarily imply that the component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0024] In the description of the embodiments of the present invention, “a plurality of” means at least 2.

[0025] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0026] Example 1:

[0027] A new type of stream drum includes a drum body 1 and a drum cover 2. The drum body 1 and the drum cover 2 form a hollow disc-shaped structure. The interior of the drum body 1 is filled with mixed gravel 3 of different sizes and densities. Several annular guide members 4 are concentrically arranged on the bottom of the inner part of the drum body 1. A guide groove 5 is formed between two adjacent annular guide members 4. The annular guide members 4 are provided with a through guide port 6. The outer side of the outermost annular guide member 4 is provided with a radial guide member 7 along the normal direction. The radial guide member 7 is made of extruded board material and is arranged between the outermost annular guide member 4 and the inner wall of the drum body 1. A sound hole 8 is provided on the drum cover 2, and a non-woven fabric anti-leakage net 9 is provided at the bottom of the drum cover 2 to prevent the internal gravel 3 from leaking out. The drum body 1 and the drum cover 2 are fixed together by a threaded connection to ensure the stability of the structure. The outer surface of the drum body 1 is provided with an anti-slip texture to facilitate the player's stable grip and operation.

[0028] The number of ring-shaped guides and the number of radial guides are not fixed, and their sizes and positions need to be determined according to the tone adjustment.

[0029] Example 2:

[0030] Similar to Example 1, except that the shape and number of the radial deflectors 7 can be adjusted as needed to accommodate different timbre and sound effects. Furthermore, the drum body 1 and drum cover 2 can be fastened together by snap-fitting or gluing to meet different production and usage requirements.

[0031] Example 3:

[0032] Similar to Embodiment 1 and Embodiment 2, except that the outer surface of the drum body 1 is provided with a holding handle, so as to be more convenient for the player to hold and operate the stream drum.

[0033] As can be seen from the above embodiments, the novel stream drum has the advantages of simple structure, rich tone, good resonance effect, stable structure, convenient holding and operation, etc., and can meet the different needs of players and improve the comfort and stability of performance.

[0034] The utility model has the following advantages:

[0035] 1. Diversity of tone and sound effect:

[0036] By using mixed gravel of different sizes and densities, more diversified tone and sound effect can be produced, thereby meeting the needs of players for different music styles and expressiveness. The gravel inside the traditional stream drum is often single, which limits the variation of tone, while the present scheme greatly enriches the tone levels through the design of mixed gravel.

[0037] 2. Resonance effect and tone optimization:

[0038] The annular flow guide and the radial flow guide are both made of extruded plate material, which can increase the friction and flowability of the stones (gravel) during the flow process, thereby optimizing the tone performance and resonance effect. The flow guide made of extruded plate material can also effectively absorb and disperse vibration energy, making the tone more mellow and full, and the resonance effect more lasting. The flow guide structure of the traditional stream drum is often relatively simple, which cannot fully stimulate the flowability and resonance effect of the gravel, resulting in monotonous tone and lack of level.

[0039] 3. Stability of structure:

[0040] The drum body and the drum cover are fixed by screw connection, buckle connection or adhesion, which ensures the stability of the structure and effectively prevents the leakage of gravel, thereby ensuring the purity of the tone and the persistence of the resonance effect. The traditional stream drum often has deficiencies in structural stability, which affects the tone and resonance effect.

[0041] 4. Easy to hold and operate:

[0042] The outer surface of the drum body is provided with anti-skid texture or holding handle, which is convenient for the player to hold and operate stably, and improves the comfort and stability of performance. The traditional stream drum often lacks such design, which makes the player feel tired or unstable during long-time performance.

[0043] 5. Saving of material cost:

[0044] While maintaining timbre and resonance, material costs were reduced through optimized structural design. For example, the use of extruded polystyrene for the flow guide met functional requirements while reducing costs. Traditional stream drums often use a limited selection of materials, with a corrugated cardboard interior and a less-than-optimized structural design, resulting in higher material costs.

[0045] In summary, this solution surpasses traditional technologies in terms of diverse tones and sound effects, optimized resonance and tone, structural stability, ease of grip and operation, and material cost savings. These advantages make the new Xishui drum more competitive and attractive in the musical instrument market.

[0046] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without creatively designing a structure and embodiment similar to the technical solution, they shall fall within the scope of protection of the present invention.
