Abstract
Description
Technical Field
[0001] This utility model relates to the field of percussion instrument technology, and in particular to a hand drum. Background Technology
[0002] The hand drum is a major category of drums and a percussion instrument. Its name varies from region to region and among different ethnic groups, and its manufacturing methods also differ slightly. Some existing hand drums have complex overall structures, and during use, the sound quality they produce is poor, which not only limits their application but also results in subpar performance. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art. This invention provides a hand drum with a simple structure and excellent sound quality.
[0004] To solve the above problems, this utility model proposes a hand drum, which includes a first drum body, a second drum body and a third drum body from bottom to top;
[0005] Both the first and second drum bodies are trumpet-shaped structures, and the connection between the first and second drum bodies is a drum waist structure; the third drum body is an annular structure, the cross-sectional area of the third drum body is smaller than that of the second drum body, the third drum body is coaxially arranged with the second drum body, and the connection between the inner walls of the third drum body and the second drum body forms an echo section.
[0006] As an improvement to the above technical solution, an annular transition portion is provided from the top of the second drum body to the third drum body, and the diameter of the annular transition portion is consistent with the opening at the top of the second drum body.
[0007] As an improvement to the above technical solution, the ratio of the diameter of the third drum body to the diameter of the annular transition portion is 0.85-0.93.
[0008] As an improvement to the above technical solution, a drum surface mounting part is provided on the inner wall of the top opening of the third drum body, and the cross-sectional area of the drum surface mounting part gradually decreases from the bottom to the top.
[0009] As an improvement to the above technical solution, the height ratio of the first drum body to the second drum body is 1.6-2.1.
[0010] As an improvement to the above technical solution, the third drum body is covered with a sheepskin drumhead.
[0011] As an improvement to the above technical solution, the connection between the first drum body and the second drum body is a circular arc transition structure.
[0012] The following are the beneficial effects of implementing this utility model:
[0013] This utility model of a hand drum comprises, from bottom to top, a first drum body, a second drum body, and a third drum body. The connection between the first and second drum bodies is a drum waist structure, and the third drum body is a ring structure with a smaller cross-sectional area than the second drum body. The connection between the inner wall of the third and second drum bodies forms an echo section, which, together with the third drum body, forms an echo groove structure, improving the sound quality of the hand drum and making its tone more melodious and pleasant. Attached Figure Description
[0014] Figure 1 This is a perspective view of a hand drum according to an embodiment of the present invention;
[0015] Figure 2 This is a cross-sectional view of a hand drum according to an embodiment of the present invention. Detailed Implementation
[0016] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.
[0017] See Figure 1 and Figure 2 As shown, this utility model embodiment provides a hand drum, which includes a first drum body 1, a second drum body 2 and a third drum body 3 from bottom to top.
[0018] This invention improves the sound quality of the hand drum by modifying its internal structure to change the echo pattern inside the drum body.
[0019] Specifically, the first drum body 1 and the second drum body 2 are both trumpet-shaped structures, and the connection between the first drum body 1 and the second drum body 2 is a drum waist structure 21; the third drum body 3 is an annular structure, the cross-sectional area of the third drum body 3 is smaller than that of the second drum body 2, the third drum body 3 and the second drum body 2 are coaxially arranged, and the connection between the inner wall of the third drum body 3 and the second drum body 2 forms an echo section 31.
[0020] The hand drum of this utility model comprises, from bottom to top, a first drum body 1, a second drum body 2, and a third drum body 3. The connection between the first drum body 1 and the second drum body 2 is a drum waist structure. The third drum body 3 has a ring-shaped structure, and its cross-sectional area is smaller than that of the second drum body 2. An echo section 31 is formed at the connection between the inner wall of the third drum body 3 and the second drum body 2. The echo section 31 and the third drum body 3 form an echo groove structure, improving the sound quality of the hand drum and making its tone more melodious and pleasant.
[0021] Preferably, the top of the second drum body 2 to the third drum body 3 is further provided with an annular transition portion 4, the diameter of which is consistent with the opening at the top of the second drum body 2. The annular transition portion 4 cooperates with the third drum body 3, extending the length of the echo groove and increasing the structural layers of the echo groove, thereby further improving the sound quality of the hand drum.
[0022] More preferably, the ratio of the diameter of the third drum body 3 to the diameter of the annular transition portion 4 is 0.85-0.93.
[0023] More preferably, the inner wall of the top opening of the third drum body 3 is provided with a drum surface mounting part 32, and the cross-sectional area of the drum surface mounting part 32 gradually decreases from the bottom to the top.
[0024] Preferably, the height ratio of the first drum body 1 to the second drum body 2 is 1.6-2.1.
[0025] Preferably, the third drum body 3 is covered with a sheepskin drumhead.
[0026] Preferably, the junction between the first drum body 1 and the second drum body 2 is a rounded transition structure. The rounded transition structure can optimize the shape of the hand drum, making it more rounded and beautiful.
[0027] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
