Description

[Technical Field]

[0001] The present invention relates to a drum support device and a drum device. [Background technology]

[0002] Patent Document 1 discloses a drum support device (bearing portion) for rotatably supporting a concert drum, a type of drum, on a stand. The drum support device in Patent Document 1 has a rotating shaft (shaft portion) attached to the stand, and a cushioning material that connects the rotating shaft to the drum body (drum shell). Patent Document 1 discloses that the cushioning material is a cylindrical body made of elastically stretchable rubber, and is interposed between the rotating shaft and the outer surface of the body. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-173417 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when the cushioning material in Patent Document 1 is made of rubber, the vibrations generated when the drum is struck are absorbed by the cushioning material and are less likely to be transmitted to the floor via the stand. When playing drums that are placed on the floor, such as concert drums, it is important not only to consider the reverberation of the sound generated by the drum itself based on the vibrations caused by the drum strike, but also to consider the reverberation of the sound that occurs from the floor as the vibrations are transmitted from the drum to the floor via the stand. Therefore, if the drum vibrations are absorbed by the cushioning material, there is a problem in that the reverberation of the sound when the drum is played is insufficient.

[0005] Furthermore, in the drum support device of Patent Document 1, the cushioning material is simply interposed between the rotating shaft and the outer surface of the drum body. Therefore, the cushioning material may expand and contract in the radial direction of the drum (body) as the drum vibrates in response to being struck. In this case, the vibration of the drum in response to being struck is absorbed by the cushioning material, making it difficult for the vibration to be transmitted to the floor via the stand. This results in a problem of insufficient resonance when the drum is played.

[0006] The present invention has been made in consideration of the above-mentioned circumstances, and aims to provide a drum support device that can improve the resonance of the sound when playing the drums, and a drum device equipped with the same. [Means for solving the problem]

[0007] A first aspect of the present invention is a drum support device for supporting a drum body on a stand, the drum support device including a spring that connects the drum body and the stand.

[0008] A second aspect of the present invention is a drum support device for supporting the drum body on a stand, comprising an elastic body connecting the drum body and the stand, wherein the elastic body elastically deforms only in a direction perpendicular to the radial direction of the drum.

[0009] A third aspect of the present invention is a drum device comprising a drum, a stand that supports the body of the drum, and the drum support device, wherein the drum support device is provided on both sides of the drum in the radial direction of the drum. [Effects of the Invention]

[0010] According to the present invention, it is possible to improve the resonance of the sound produced when playing drums. [Brief explanation of the drawings]

[0012] Hereinafter, one embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 1 and 2, the drum device 1 of this embodiment includes a drum 2, a stand 3 that supports the drum 2, and a drum support device 4 that supports the body 11 of the drum 2 relative to the stand 3.

[0013] As shown in Figures 1 to 3, the drum 2 of this embodiment is a so-called concert bass drum. The drum 2 has a body 11 and a head 12. The body 11 has an opening into which the head 12 is attached. Specifically, the body 11 is formed in a cylindrical shape with openings on both ends. The diameter of the body 11 does not change in the axial direction of the body 11. The head 12, which covers the opening of the body 11, forms the striking surface 2a of the drum 2 that is struck with a stick or the like. In this embodiment, the radial direction of the opening of the body portion 11 is defined as the radial direction RD of the drum 2 (see FIGS. 2 and 3). The direction in which the axis A1 of the body portion 11 extends, passing through the center of the opening of the body portion 11 and perpendicular to the radial direction RD of the body portion 11 and the striking surface 2a of the head 12, is defined as the axial direction AD of the drum 2 (see FIGS. 2 and 3). The direction around the axis A1 of the body portion 11 is defined as the circumferential direction CD of the drum 2 (see FIG. 2). In this specification, the circumferential direction CD of the drum 2 corresponds to the direction perpendicular to the radial direction RD and the axial direction AD of the drum 2.

[0014] As shown in FIGS. 1 and 2 , the stand 3 has legs 21 that are placed on the floor, and two support parts 22 that extend upward from the legs 21 and are spaced apart from each other. The drum 2 is disposed between the two support parts 22 and is attached to the two support parts 22 via a drum support device 4. Each support part 22 has a connection part 23 located at its upper end for connecting the drum support device 4, which will be described later, to the support part 22. The connection parts 23 are located on both sides of the drum 2 in the radial direction RD of the drum 2.

[0015] The specific configuration of the legs 21 and each support part 22 may be arbitrary. In this embodiment, the legs 21 have multiple casters 25. This allows the drum device 1 to be easily moved on the floor. Each support part 22 is formed of a rod-shaped member bent convexly upward, and both longitudinal ends of the support part 22 are fixed to the legs 21. As shown in FIG. 5 , the connection part 23 located at the upper end of the support part 22 has a first clamp part 231 that clamps the upper end of the support part 22 and a second clamp part 232 that clamps the rotation shaft 40 of the drum support device 4 described below. When the rotation shaft 40 is clamped by the second clamp part 232, the rotation shaft 40 hardly rotates around the axis A2 of the rotation shaft 40 relative to the connection part 23 (stand 3).

[0016] 2, the drum support devices 4 are located on both sides of the drum 2 in the radial direction RD of the drum 2. Each drum support device 4 includes a spring 30 (elastic body), a rotating shaft 40, a rotating shaft-side fixing portion 50, and a body-side fixing portion 60 (mounting portion-side fixing portion).

[0017] The spring 30 is elastically deformable and connects the body 11 and the stand 3. The spring 30 is disposed on the outer peripheral surface 11a of the body 11 and elastically deforms only in the circumferential direction CD (orthogonal direction) of the drum 2. As shown in Figures 6 and 7, the spring 30 of this embodiment is made of steel or metal wire and has a spring body 31 and two extensions 32 and 33. The spring body 31 is formed in a helical cylindrical shape. The two extensions 32 and 33 extend radially from both axial ends of the spring body 31. In this embodiment, the two extensions 32 and 33 extend in approximately the same direction from the spring body 31. Therefore, the two extensions 32 and 33 face each other in the axial direction of the spring body 31. Furthermore, the extension directions of the two extensions 32 and 33 are both perpendicular to the axis A3 of the spring body 31. Therefore, the two extensions 32 and 33 are parallel to each other. Each of the extension wire portions 32, 33 has an insertion portion 35 for passing a fixing screw 91, 92 (see FIG. 4). The insertion portion 35 is located at the tip end in the extension direction of each of the extension wire portions 32, 33. The insertion portion 35 in the illustrated example is formed by bending a wire material into a generally arc shape.

[0018] In the above-described spring 30, the two extensions 32 and 33 may extend from the spring body 31 in different directions from each other, for example. In the following description, one of the ends of the spring body 31 in the axial direction may be referred to as a first end 31A, and the other may be referred to as a second end 31B. In addition, the extension line portion 32 extending from the first end 31A of the spring body 31 may be referred to as a first extension line portion 32, and the extension line portion 33 extending from the second end 31B of the spring body 31 may be referred to as a second extension line portion 33.

[0019] As shown in FIG. 2, the rotating shafts 40 support the drum 2 rotatably relative to the stand 3. The rotating shafts 40 are located on both sides of the drum 2 in the radial direction RD of the drum 2. The axes A2 of the two rotating shafts 40 both extend in the radial direction RD of the drum 2. The axes A2 of the two rotating shafts 40 coincide with each other. Furthermore, the axis A2 of each rotating shaft 40 intersects with the axis A1 of the body portion 11. Furthermore, the axis A2 of each rotating shaft 40 is located at a middle position of the body portion 11 in the axial direction AD of the drum 2.

[0020] The axis A2 of each rotating shaft 40 may be slightly inclined with respect to the radial direction RD of the drum 2, for example. The axes A2 of the two rotating shafts 40 may be slightly misaligned with each other, for example. The axis A2 of the rotating shaft 40 does not have to intersect with the axis A1 of the body portion 11, for example. However, it is more preferable that the axis A2 of the rotating shaft 40 be located near the axis A1 of the body portion 11. The axis A2 of the rotating shaft 40 may be located away from the middle of the body portion 11 in the axial direction AD of the drum 2, for example. However, it is more preferable that the axis A2 of the rotating shaft 40 be located near the middle of the body portion 11.

[0021] 2 and 5, the rotation shaft 40 of this embodiment is located between the connection part 23 of the stand 3 and the spring 30. Therefore, the rotation shaft 40 is fixed at a desired rotation position with respect to the connection part 23 of the stand 3. In addition, the rotation shaft 40 is connected to the body part 11 by the spring 30.

[0022] As shown in Figures 3 and 4, the springs 30 are located on both sides of the rotation shaft 40 as viewed in the axial direction of the rotation shaft 40. Specifically, the springs 30 are located on both sides of the rotation shaft 40 in the axial direction AD of the drum 2. It is preferable that the number of springs 30 located on both sides of the rotation shaft 40 is equal. In the illustrated example, one spring 30 is located on each side of the rotation shaft 40. Furthermore, the characteristics and shape of the springs 30, and the distance between the rotation shaft 40 and the springs 30, may differ between the springs 30 located on both sides of the rotation shaft 40, but it is more preferable that they are the same.

[0023] As shown in FIGS. 4 and 5, the rotary shaft side fixing portion 50 is fixed to the rotary shaft 40. The rotating-shaft-side fixed portion 50 has a first contact surface 50a that faces the barrel-side fixed portion 60 in the circumferential direction CD of the drum 2. The first end 31A of the spring body 31 and the first extension portion 32 come into contact with the first contact surface 50a. The tip of the first extension portion 32 is fixed to the first contact surface 50a by screwing. Specifically, a screw 91 is passed through the insertion portion 35 of the first extension portion 32 and the portion of the rotating-shaft-side fixed portion 50 that constitutes the first contact surface 50a, and then threaded into a nut 95, thereby fixing the tip of the first extension portion 32 to the first contact surface 50a. Note that the screw 91 may, for example, be passed through the insertion portion 35 of the first extension portion 32 and then threaded into the portion of the rotating-shaft-side fixed portion 50 that constitutes the first contact surface 50a.

[0024] The barrel-side fixed part 60 is fixed to the barrel 11 (mounting part) and is positioned at a distance from the rotary shaft-side fixed part 50 in the circumferential direction CD (orthogonal direction) of the drum 2. The barrel-side fixed portion 60 has a second contact surface 60a that faces the first contact surface 50a of the rotating-shaft-side fixed portion 50 in the circumferential direction CD of the drum 2. The second end 31B of the spring body 31 and the second extension portion 33 come into contact with the second contact surface 60a. The tip of the second extension portion 33 is fixed to the second contact surface 60a by screwing. Specifically, a screw 92 is passed through the insertion portion 35 of the second extension portion 33 and the portion of the barrel-side fixed portion 60 that constitutes the second contact surface 60a, and then threaded into a nut 96, thereby fixing the tip of the second extension portion 33 to the second contact surface 60a. Note that the screw 92 may, for example, be passed through the insertion portion 35 of the second extension portion 33 and then threaded into the portion of the barrel-side fixed portion 60 that constitutes the second contact surface 60a.

[0025] The area of ​​the first contact surface 50a that comes into contact with the first end 31A of the spring body 31, and the area of ​​the second contact surface 60a that comes into contact with the second end 31B of the spring body 31, are each formed of a sheet-like cushioning material 70. The cushioning material 70 may be any material that can absorb impacts caused by a collision, and may be, for example, a urethane sheet. The specific configurations of the rotary shaft side fixed part 50 and the barrel side fixed part 60 will be further described below.

[0026] The rotary shaft side fixing portion 50 has a first base plate 51 and a first spring fixing member 52 . The first base plate 51 is formed in a generally flat plate shape. The first base plate 51 is positioned so that its thickness direction faces the radial direction RD of the drum 2. Therefore, a first surface 51a of the first base plate 51 facing the thickness direction faces the outer peripheral surface 11a of the barrel portion 11. The rotating shaft 40 is fixed to a second surface 51b of the first base plate 51 facing the opposite side to the first surface 51a. An axis A2 of the rotating shaft 40 extends from the first base plate 51 in its thickness direction. In FIG. 4, a portion of the first base plate 51 located to the right of the axis A2 of the rotating shaft 40 is shown by a virtual line.

[0027] The first spring fixing member 52 is fixed to the first surface 51a of the first base plate 51 by screwing. The first spring fixing member 52 has a first contact surface 50a of the rotating shaft side fixing part 50. The first spring fixing member 52 in the illustrated example is formed by bending a flat plate into an L shape, but is not limited to this and may be formed into any shape, such as a block shape.

[0028] The body-side fixing part 60 has a second base plate 61 and a second spring fixing member 62 . The second base plate 61 is formed in a generally flat plate shape. The second base plate 61 is positioned so that its plate thickness direction faces the radial direction RD of the drum 2. A first surface 61a of the second base plate 61 facing the plate thickness direction faces the first surface 51a of the first base plate 51. A second surface 61b of the second base plate 61 facing the opposite side to the first surface 61a faces the outer peripheral surface 11a of the body portion 11. The second base plate 61 is fixed to the outer peripheral surface 11a of the body portion 11 with screws 93.

[0029] The second spring fixing member 62 is fixed to the first surface 61a of the second base plate 61 by screwing. The second spring fixing member 62 has a second contact surface 60a of the barrel-side fixing portion 60. Therefore, the second spring fixing member 62 is positioned at a distance from the first spring fixing member 52 in the circumferential direction CD (orthogonal direction) of the drum 2. The second spring fixing member 62 in the illustrated example is formed by bending a flat plate into an L-shape, but is not limited to this and may be formed into any shape, such as a block shape.

[0030] 4, the first and second base plates 51, 61 of this embodiment extend on both sides of the rotation shaft 40 in the axial direction AD of the drum 2, as viewed from the axial direction of the rotation shaft 40. The first and second spring fixing members 52, 62 are located on both sides of the rotation shaft 40 in the axial direction AD of the drum 2. This allows the springs 30 to be disposed on both sides of the rotation shaft 40 in the axial direction AD of the drum 2.

[0031] In the illustrated example, the two extensions 32, 33 of each spring 30 arranged on both sides of the rotation shaft 40 both extend in a direction approaching the rotation shaft 40 relative to the spring body 31. Note that the direction in which the two extensions 32, 33 of each spring 30 extend from the spring body 31 may be, for example, a direction away from the rotation shaft 40 or a direction intersecting the direction in which the rotation shaft 40 and the spring 30 are aligned.

[0032] In the illustrated example, the direction in which the first contact surface 50a (first spring fixing member 52) and the second contact surface 60a (second spring fixing member 62) are aligned is the same on both sides of the rotation shaft 40. Note that the direction in which the first contact surface 50a (first spring fixing member 52) and the second contact surface 60a (second spring fixing member 62) are aligned may be opposite on both sides of the rotation shaft 40, for example.

[0033] In the illustrated example, the first base plate 51 covers the spring 30, the first and second spring fixing members 52, 62, and the screw 93 that fixes the second base plate 61 to the body 11 from the radial outside of the drum 2. The first base plate 51 covers the spring 30, thereby protecting the spring 30 and preventing the user of the drum device 1 from accidentally touching the spring 30. Furthermore, the first base plate 51 covers the screw 93 that fixes the second base plate 61 to the body 11, thereby preventing the second base plate 61 from being accidentally detached from the body 11.

[0034] As described above, in the drum support device 4 and the drum device 1 including the same according to this embodiment, the drum body 11 of the drum 2 and the stand 3 are connected by the spring 30. The spring 30 is made of steel or metal, which has higher rigidity than rubber. Therefore, compared to when the stand 3 and the drum body 11 are connected by rubber, vibrations of the drum 2 generated when the drum 2 is struck are not completely absorbed by the spring 30 and are transmitted to the stand 3 via the spring 30. In other words, absorption of the vibrations of the drum 2 by the spring 30 is suppressed. This allows the vibrations of the drum 2 caused by striking to be efficiently transmitted to the stand 3 and the floor in turn. This improves the reverberation of the sound produced when the drum is played.

[0035] Furthermore, the spring 30 connecting the stand 3 and the body 11 has less variation in properties such as elastic modulus compared to rubber. This stabilizes the manner in which the drum 2 oscillates relative to the stand 3 when struck. This makes it possible to stably manufacture drum support devices 4 that satisfy desired conditions (conditions for the manner in which the drum 2 oscillates relative to the stand 3 when struck).

[0036] Furthermore, the spring 30 can easily adjust how easily the drum 2 swings, simply by changing its spring constant. This makes it easy to adjust the balance between the playability of the drum 2 and the resonant tone (sound sustain) of the sound of the drum 2. To explain this point, if the drum 2 swings easily, the resonant tone (sound sustain) of the sound of the drum 2 will improve, but the playability of the drum 2 will decrease. On the other hand, if the drum 2 does not swing easily, the playability of the drum 2 will improve, but the resonant tone (sound sustain) of the sound of the drum 2 will decrease. Therefore, by changing the spring constant of the spring 30 to appropriately adjust the ease with which the drum 2 swings, it is possible to adjust the balance between the playability of the drum 2 and the resonant tone (sound sustain) of the sound of the drum 2.

[0037] Furthermore, in the drum support device 4 of this embodiment and the drum device 1 including it, the elastic body (spring 30) connecting the drum body 11 of the drum 2 to the stand 3 elastically deforms only in the direction perpendicular to the radial direction RD of the drum 2. Therefore, when the drum 2 is struck, the elastic body does not expand or contract in the radial direction RD of the drum 2. This prevents the vibration of the drum 2 caused by the strike from being absorbed by the elastic body, and the vibration of the drum 2 caused by the strike can be efficiently transmitted to the stand 3 and the floor in turn. This improves the reverberation of the sound when the drum is played.

[0038] Furthermore, the elastic body (spring 30) connecting the body 11 and the stand 3 elastically deforms only in a direction perpendicular to the radial direction RD of the drum 2, thereby restricting the direction in which the drum 2 swings relative to the stand 3 when struck. This makes it easier for the performer to strike the drum 2, thereby improving the playability of the drum 2.

[0039] Furthermore, in the drum support device 4 of this embodiment, springs 30 that elastically deform only in a direction perpendicular to the radial direction RD of the drum 2 are located on both sides of the rotation shaft 40 when viewed from the axial direction of the rotation shaft 40. Therefore, when the drum 2 is struck, the springs 30 located on both sides of the rotation shaft 40 each elastically deform, making it easier for the drum 2 to swing around the rotation shaft 40 relative to the stand 3. This makes it possible to ensure both the playability of the drum 2 and the resonance (sound extension) of the sound of the drum 2. Additionally, by adjusting the position of each spring 30 relative to the rotation shaft 40 (the distance between the rotation shaft 40 and each spring 30), it is possible to easily adjust the ease with which the drum 2 swings. This allows the ease with which the drum 2 swings to be appropriately adjusted, thereby adjusting the balance between the playability of the drum 2 and the resonance of the sound (sound sustain) of the drum 2.

[0040] Furthermore, in the drum support device 4 of this embodiment, the spring 30 has two extensions 32, 33 that extend in the radial direction RD of the spring body 31 from both axial ends of the spring body 31. The tip ends of the two extensions 32, 33 are fixed to the rotating shaft-side fixing part 50 and the barrel-side fixing part 60 (mounting part-side fixing part) by screws. This allows both axial ends of the spring 30 to be easily fixed to the rotating shaft-side fixing part 50 and the barrel-side fixing part 60 independently. It is difficult to fix both ends of the spring body 31 formed in a spiral tube shape by screwing them independently to the rotating-shaft-side fixed part 50 and the barrel-side fixed part 60. This difficulty arises from the fact that it is difficult to pass the screws 91, 92 for fixing one end of the spring body 31 to the rotating-shaft-side fixed part 50 or the barrel-side fixed part 60 through the inside of the spring body 31, and also because it is difficult to move the screws 91, 92 that have been passed through the inside of the spring body 31 inside the spring body 31 and screw them into the rotating-shaft-side fixed part 50 or the barrel-side fixed part 60.

[0041] Furthermore, in the drum support device 4 of this embodiment, the spring 30 is arranged between the rotating shaft side fixing portion 50 and the body side fixing portion 60, which are aligned in the circumferential direction CD (orthogonal direction) of the drum 2, thereby enabling the spring 30 to reliably expand and contract in the circumferential direction CD of the drum 2.

[0042] In the drum support device 4 of this embodiment, the two extensions 32, 33 of the spring 30 face each other in the axial direction of the spring body 31 and are perpendicular to the axial direction of the spring body 31. The first end 31A and the first extension 32 of the spring body 31 contact the first contact surface 50a of the rotary shaft-side fixed part 50, and the second end 31B and the second extension 33 of the spring body 31 contact the second contact surface 60a of the barrel-side fixed part 60. Therefore, even if the rotating-shaft-side fixed part 50 and the barrel-side fixed part 60 move relative to each other in response to a strike on the drum 2, the axial direction of the spring body 31 can be maintained in a state that is generally perpendicular to the first contact surface 50a of the rotating-shaft-side fixed part 50 and the second contact surface 60a of the barrel-side fixed part 60. This makes it possible to suppress or prevent the spring body 31 from being significantly bent and curved. This effectively prevents the spring body 31 from being significantly bent and curved, which can cause the drum 2 to sway unstably relative to the stand 3 when the drum 2 is struck. This suppresses or prevents a decrease in playability of the drum 2.

[0043] Furthermore, in the drum support device 4 of this embodiment, the areas of the first contact surface 50a and the second contact surface 60a that come into contact with the first end 31A and the second end 31B of the spring body 31 are formed with a sheet-like cushioning material 70. Therefore, even if the first end 31A and the second end 31B of the spring body 31 collide with the rotating-shaft-side fixed portion 50 and the body-side fixed portion 60 due to relative movement in perpendicular directions between the rotating-shaft-side fixed portion 50 and the body-side fixed portion 60 in response to a strike on the drum 2, the impact of the collision can be absorbed by the cushioning material 70. This can suppress or prevent the generation of impact noise due to the collision. It is undesirable for the drum device 1 to unexpectedly generate a sound other than the desired sound (e.g., the sound of striking the striking surface 2a). Therefore, being able to suppress or prevent the generation of the impact noise is extremely effective.

[0044] Furthermore, in the drum support device 4 of this embodiment, the spring 30 (elastic body) connecting the body 11 and the stand 3 elastically deforms only in the circumferential direction CD of the drum 2 (a direction perpendicular to the radial direction RD and axial direction AD of the drum 2). Therefore, when the spring 30 elastically deforms by striking the striking surface 2a of the drum 2 facing the axial direction AD of the drum 2, it is possible to effectively prevent the striking surface 2a of the drum 2 from being displaced in the axial direction AD of the drum 2 relative to the stand 3. This makes it easier for the performer to strike the striking surface 2a of the drum 2, which in turn improves the playability of the drum 2.

[0045] Although the present invention has been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

[0046] In the present invention, the springs 30 arranged on both sides of the rotating shaft 40 as viewed in the axial direction of the rotating shaft 40 are only required to be elastically deformable at least in a direction perpendicular to the rotating shaft 40. Therefore, the springs 30 arranged on both sides of the rotating shaft 40 are not limited to being located on both sides of the rotating shaft 40 in the axial direction AD of the drum 2, but may also be located on both sides of the rotating shaft 40 in the circumferential direction CD of the drum 2, for example.

[0047] In the present invention, it is sufficient that the rotating shaft 40 and the spring 30 are connected at least between the drum 2 and the stand 3. Therefore, the rotating shaft 40 may be located, for example, between the body 11 and the spring 30. In this case, the rotating shaft 40 is fixed to the body 11. The rotating shaft 40 is also connected to the stand 3 by the spring 30. In this configuration, for example, the tip of the first extension portion 32 of the spring 30 may be fixed by a screw to a rotating shaft-side fixing portion 50 fixed to the rotating shaft 40. The tip of the second extension portion 33 of the spring 30 may be fixed by a screw to a stand-side fixing portion (mounting portion-side fixing portion) fixed to the stand 3 (mounting portion). The stand-side fixing portion may be formed integrally with the connecting portion 23 of the stand 3, for example. In view of the above, the drum support device of the present invention may, for example, comprise a rotating shaft side fixing portion 50 fixed to the rotating shaft 40, and an attachment portion side fixing portion (body side fixing portion 60, stand side fixing portion) fixed to an attachment portion of either the body portion 11 or the stand 3 and positioned at a distance perpendicular to the rotating shaft side fixing portion 50.

[0048] The drum support device 4 of the present invention may not include, for example, the rotation shaft 40. In this case, the body 11 and the stand 3 may be directly connected by the spring 30.

[0049] In the present invention, the spring 30 connecting the body 11 and the stand 3 is not limited to elastically deforming in the circumferential direction CD of the drum 2, but may be elastically deformed in any direction (for example, the radial direction RD or axial direction AD of the drum 2).

[0050] In the present invention, the body 11 and the stand 3 are not limited to being connected by the spring 30, but may be connected by at least an elastic body that is elastically deformable. The elastic body may be, for example, rubber.

[0051] In the present invention, when the elastic body connecting the body 11 and the stand 3 is other than a spring, the elastic body only needs to elastically deform in at least a direction perpendicular to the radial direction RD of the drum 2. Therefore, the direction in which the elastic body other than a spring elastically deforms may be, for example, the axial direction AD of the drum 2 or a direction inclined with respect to both the axial direction AD and the circumferential direction CD of the drum 2.

[0052] In the present invention, the drum is not limited to a concert bass drum, but may be any drum having a body with at least one opening and a head that covers the opening in the body. The drum may be, for example, a snare drum, timpani, bongo, conga, etc. [Explanation of symbols]
