The first folding wall 20 can be folded toward the inside of the drum body 10 obliquely with respect to the inner wall of the drum body 10. More specifically, the first folding wall 20 can be integrally formed with one side wall of the drum body 10. In the present embodiment, the boundary between the first folding wall 20 and the side wall can be directly bent, for example, to form a flange 21, which can be supported by a drum, for example, and the flange The 21 series can be closely fitted to the drum skin so that the drum skin can be stably supported for tensioning, and the drum skin can produce a full sound effect. In other possible embodiments, the first folding wall 20 and the side wall may also be connected with a horizontally extending or curved shape interval (not shown), and the drum skin may also bear the spacing. The segment further increases the support area of the drum skin.

During the manufacturing process, the drum body 10 and the first folding wall 20 and the second folding wall 30 can be formed, for example, by using a metal material. For example, the metal material can be easily bent and has For ductility, the metal material may be, for example, a carbon steel material or a stainless steel material. Further, the first body wall 10 and the first folding wall 20 and the second folding wall 30 can be integrally molded by using a metal material through a rolling process and a bending process, and the first folding wall 20 can be formed. And a folding space 22 is formed between the second folding wall 30 and the inner wall of the drum body 10.

Furthermore, the first folding wall 20 can be inclined between 30 degrees and 45 degrees with respect to the inner wall of the drum body 10, for example, between the first folding wall 20 and the inner wall of the drum body 10. For example, it may have an angle 23, which may be between 30 degrees and 45 degrees, such that the first folding wall 20 can be angled between 45 degrees and 60 degrees, for example, with the drum skin. Preferably, the first folding wall 20 and the drum skin are sandwiched at an angle of 45 degrees, so that the drum skin can produce an optimal vibration effect and produce a full sound. However, the first folding wall 20 It can also be set to any other angle according to the requirements, and can produce various sounds of different sound effects.

For example, the second folding wall 30 can extend in the opposite direction with respect to the first folding wall 20, for example. Up to the inner wall of the drum body 10, and the first folding wall 20 and the second folding wall 30 are formed into a substantially dome shape, and more specifically, the first folding wall 20 and the second folding wall The inner wall of the drum body 10 and the inner wall of the drum body 10 can be configured to form the folding space 22, and the folding space 22 can have a contour of an isosceles triangle.

The side of the drum body 10 is provided with a convex portion 40 in a radially outward direction. The side surface of the drum body 10 can be circumferentially spaced apart to provide a plurality of openings 50. The openings 50 are spaced apart from each other. Above and below the convex portion 40, further, the convex portion 40 is recessed radially outwardly on the inner wall of the drum body 10, and the resonance effect of the resonance space 11 of the drum body 10 is increased, so that the resonance is achieved. Space 11 produces a fuller sound effect. The apertures 50 can be used, for example, for assembly of a plurality of positioning devices.

It is worth mentioning that when the drum skin is vibrated by an external force, for example, the first folding wall 20 and the second folding wall 30 can simultaneously generate a resonance effect, and the folding space 22 can form a resonance. The chamber can further increase the resonance effect of the sound, produce better sound saturation and sound wave amplitude, and enhance the sustain effect. In addition, the drum skin can be tightly supported by the flange 21 and the angle between the first folding wall 20 and the drum skin is appropriately set, so that the vibration of the drum can be completed. The ground is transmitted to the drum body 10, and the sound resonance space 11 is used to achieve the best resonance effect.

Referring to the second embodiment shown in FIG. 3 to FIG. 5, the present invention further provides a drum 2 comprising the drum frame structure 1 as described above, and the drum 2 may further comprise at least one drum module 60 and a plurality of positioning devices 70, the drumhead assembly 60 is disposed on the opening 12, the drum assembly The 60 may include a drum skin 61 and a frame member 62 that covers the opening 12 . The positioning device 70 is spaced apart from the drum body 10. Each positioning device 70 is connected between the drum assembly 60 and the drum body 10. Each positioning device 70 includes a fixing member 71 and at least one screw member. The fixing member 71 is disposed on the protruding portion 40 and is fixedly disposed on at least two of the openings 50. The screw member 72 passes through the frame member 62 and has a resisting end 73 and a screwing end 74. The screwing end 74 can be screwed to the fixing member 71 such that the abutting end 73 and the frame member 62 abut each other, so that the drum skin 61 can be tensioned and fixed to the drum body through the frame member 62. 10.

In a third embodiment as shown in FIG. 6, the second folding wall 30a can comprise, for example, a straight section 31 and a horizontal section 32, the straight section 31 being from the end of the first folding wall 20a along the drum body 10. One of the axial extensions, the transverse section 32 is connected to one end of the straight section 31 and the end of the transverse section 32 extends to the inner wall of the drum body 10, the first folding wall 20a and the straight section 31 and the transverse section The segment 32 can form a collapsed space with the inner wall of the drum body 10 to further increase the resonance effect of the sound.

In a fourth embodiment as shown in FIG. 7, one end of the second folding wall 30b can have a spacing gap 33 between the inner wall of the drum body 10 and the end of the second folding wall 30b. Form a free end.

In a fifth embodiment as shown in FIG. 8 to FIG. 9, the end of the second folding wall 30c is fixed to the inner wall of the drum body 10. For example, the end of the second folding wall 30c is The inner wall of the drum body 10 can be fixed to each other by welding (for example, by bonding or the like), and the second folding wall 30c is fixed to the inner wall of the drum body 10 and cannot move relative to the inner wall of the drum body 10, Therefore, when the drum body 10 produces a resonance effect of sound, the second folding wall 30c is fixed to provide a more stable resonance effect of the sound. The end of the second folded wall 30d may also include a connecting portion 34 (shown in FIG. 9) extending along the inner wall of the drum body 10 by a predetermined distance, the connecting portion 34 and the connecting portion 34 The inner walls of the drum body 10 can be fixed to each other by welding, for example.
