Description

Technical Field

[0001] This invention relates to a snare drum resonator adjustment device, and more particularly to a resonator adjustment device that allows the resonator mechanism to be installed on the adjustment device without any hand tools, thereby enabling the user to quickly remove the resonator mechanism from the adjustment device by hand. Background Technology

[0002] The snare drum is one of the most common percussion instruments in musical performances. (See also:) Figures 1A to 1C As shown, the existing small drum 50 mainly consists of a drum body 51, a lead wire mechanism 52, a connecting mechanism (not shown), and an adjusting mechanism 53. The drum body 51 has a hollow drum shell 511 and two drumheads (not shown) connected to the upper and lower ends of the drum shell 511 respectively. The lead wire mechanism 52 is located below the drum shell 511. The lead wire mechanism 52 has two lead wire connecting plates 521 arranged at intervals. The two lead wire connecting plates 521 connect multiple lead wires 522 together, so that the multiple lead wires 522 are located between the two lead wire connecting plates 521. Each lead wire connecting plate 521 is connected to a sling 523. The connecting mechanism 53 is set in the drum shell 511 to clamp one of the slings 523.

[0003] like Figure 1B and Figure 1C As shown, the adjustment mechanism 53 comprises four parts: a supporting body 531, a movable body 532, an opening / closing body 533, and a sling connecting body 534. The supporting body 531 is connected to the drum shell 511 of the drum body 51, while the movable body 532 is movably assembled to the supporting body 531 along the Z-axis direction, allowing the movable body 532 to move linearly relative to the supporting body 531 along the Z-axis direction. The opening / closing body 533 is connected to both the supporting body 531 and the movable body 532, and can drive the movable body 532 to move along the Z-axis direction. Additionally, the sling connecting body 534... The sling connecting body 534 is connected to the movable body 532, so that the sling connecting body 534 can move synchronously with the movable body 532. The sling connecting body 534 is mainly composed of a sling base 534a, a sling pressure plate 534b and two pressure plate screws 534c. The pressure plate screws 534c pass through the sling pressure plate 534b to lock it to the sling base 534a, so that the sling base 534a and the sling pressure plate 534b can be clamped to the other sling 523 of the sling mechanism 52. Then, the two sides of the sling mechanism 52 are respectively connected to the connecting mechanism 53 and the adjusting mechanism 53.

[0004] However, in order for the strap base 534a and the strap pressure plate 534b of the adjustment mechanism 53 to be clamped to the strap 523 of the coiling mechanism 52, the user needs to use a hand tool to connect the pressure plate screw 534c to both the strap base 534a and the strap pressure plate 534b simultaneously. Similarly, to separate the coiling mechanism 52 from the adjustment mechanism 53, the user also needs to use a hand tool to first loosen the pressure plate screw 534c, so that the strap pressure plate 534b is separated from the strap base 534a, and then the strap 523 can be detached from the strap base 534a and the strap pressure plate 534b. Therefore, both the installation process of the coiling mechanism 52 on the adjustment mechanism 53 and the disassembly process of the coiling mechanism 52 off the adjustment mechanism 53 require the use of hand tools, which undoubtedly increases the number of steps in the installation and disassembly process, and also increases the complexity and time consumption of the installation and disassembly process, which will cause a certain degree of inconvenience to the user.

[0005] Furthermore, each time the resonant mechanism 52 is installed on the adjustment mechanism 53, the positions where the strap base 534a and the strap pressure plate 534b of the adjustment mechanism 53 clamp the strap 523 are different each time. This results in the multiple resonant wires 522 of the resonant mechanism 52 being in different tension states, which in turn affects the sound quality produced when the snare drum 50 is struck. Specifically, when the position where the strap base 534a and the strap pressure plate 534b clamp the strap 523 is closer to the resonant wire connecting plate 521 of the resonant mechanism 52, the tension of the multiple resonant wires 522 will be too tight, resulting in the sound quality produced when the snare drum 50 is struck. If the sound is too loud, or if the position of the strap base 534a and the strap pressure plate 534b clamping the strap 523 is too far away from the strap connecting plate 521 of the strap mechanism 52, the tension of the multiple straps 522 will be too loose, resulting in a sound that is too low and unclear when the snare drum 50 is struck. Therefore, if the position of the strap base 534a and the strap pressure plate 534b clamping the strap 523 is incorrect, the snare drum 40 will not be able to produce the desired sound. The user needs to repeatedly reinstall the strap mechanism 52 onto the adjustment mechanism 53. However, repeated installation and adjustment not only increases the complexity of operation, but also significantly increases the time cost. Summary of the Invention

[0006] The main objective of this invention is to provide a reverb adjustment device with an improved structure for the strap connection body. This device allows for connection and disassembly of the reverb mechanism and the improved strap connection body without any hand tools, effectively simplifying the assembly and disassembly process. Users can quickly detach the reverb mechanism from the improved strap connection body by hand. Furthermore, each time the reverb mechanism is installed on the improved strap connection body, the tension of the reverb is maintained within an appropriate range, ensuring that the snare drum produces an ideal sound when struck. This effectively prevents the reverb from being too tight or too loose, which could cause a deviation in the snare drum's tone.

[0007] The secondary objective of this invention is to provide a sound-adjusting device with an improved structure of the opening and closing body, so that the improved opening and closing body can drive the movable body to move in multiple stages, allowing the degree of attachment of the multiple sound-adjusting wires of the sound-adjusting mechanism to the drumhead of the snare drum to vary in a variety of ways, thereby not only effectively expanding the range of snare drum timbre variations, but also improving the diversity of performance.

[0008] Another objective of this invention is to provide a linear adjustment device with an improved adjustment mechanism to reduce friction between the opening / closing body and the movable body, so that the opening / closing body can smoothly drive the movable body to move, thereby reducing the risk of malfunction between the opening / closing body and the movable body.

[0009] Another objective of this invention is to provide a retractable cord adjustment device with an improved structural form of the sling connection body. The improved sling connection body is applicable to both rope-like slings and sheet-like slings, allowing the sling connection body to flexibly match different types of slings. Thus, both retractable cord mechanisms with rope-like slings and retractable cord mechanisms with sheet-like slings can be connected to the improved sling connection body.

[0010] Another objective of this invention is to provide an improved coordination between the opening / closing body and the movable body to ensure that the opening / closing body can drive the resonator adjustment device of the movable body each time. This ensures that during the process of the opening / closing body moving the movable body to adjust the adhesion between the multiple resonators of the resonator mechanism and the drumhead of the small drum, the opening / closing body can always maintain effective contact with the movable body, effectively avoiding jamming between the opening / closing body and the movable body, which would prevent the opening / closing body from moving the movable body.

[0011] To achieve the aforementioned objective, the present invention provides a lead wire adjustment device, which includes: a lead wire mechanism and an adjustment mechanism;

[0012] The rattle mechanism has a rattle assembly and two straps connected to the rattle assembly. The adjustment mechanism includes: a support body, a movable body, a strap connecting body, and an opening / closing body. The support body is connected to a drum shell. The movable body is movably connected to the support body, allowing the movable body to move relative to the support body. The strap connecting body moves synchronously with the movable body and has a hook portion and a contact portion. The hook portion forms a hooking space, so the opening / closing body can drive the movable body to move.

[0013] The sling can extend from the cord assembly across the contact portion and hook onto the hook portion, such that the hooking space accommodates a portion of the sling, and thus another portion of the sling can simultaneously contact the contact portion.

[0014] In this embodiment, the sling connecting body has a sling base and a sling connecting wheel. The sling base is recessed to form two connecting grooves, and the connecting grooves are used to accommodate a portion of the sling, so that a portion of the sling can contact the wall surface of the connecting groove to form the contact portion. The sling connecting wheel has a connecting wheel shaft portion close to the sling base and a connecting wheel wheel portion away from the sling base, and the hooking space is formed between the connecting wheel shaft portion and the connecting wheel wheel portion, so that the sling connecting wheel forms the hook portion.

[0015] The sling connecting wheel is located between two connecting grooves, and the height of the sling connecting wheel at its highest point is lower than the height of the connecting grooves. The sling connecting body further includes a sling pressure plate, a pressure plate screw, and a connecting wheel connector. A screw rod of the pressure plate screw passes through the sling pressure plate to connect to the sling base, such that the screw head of the pressure plate screw and the sling base are clamped together in the sling pressure plate. The sling pressure plate has a recessed pressure plate space on the side facing the sling base. The connecting wheel connector has a connecting head located inside the pressure plate space and a connecting rod formed at one end of the connecting head. The connecting rod is located outside the pressure plate space and connects to the connecting wheel shaft.

[0016] Furthermore, the sling base is provided with a first fixed seat surface that contacts the sling pressure plate and a second fixed seat surface that forms the connecting groove. The connecting groove has a first turning surface adjacent to the first fixed seat surface and a groove bottom surface spaced below the second fixed seat surface. When the sling is simultaneously placed inside the hook space and inside the connecting groove, the sling contacts the first turning surface to form a first bend. The connecting groove is provided with a second turning surface on the side of the connecting groove away from the first turning surface, and the sling contacts the second turning surface to form a second bend spaced apart from the first bend.

[0017] Additionally, the movable body has a movable rod passing through the supporting body and a connecting rod intersecting the movable rod. The opening and closing body is recessed to form an opening and closing track into which the connecting rod can pass, and is pivotally connected to the supporting body, so that the opening and closing body can rotate relative to the supporting body about a rotation axis. The opposite sides of the opening and closing track are respectively provided as a track proximal end close to the rotation axis and a track distal end away from the rotation axis. A track wall surface that can contact the connecting rod is formed from the track proximal end toward the track distal end. When the opening and closing body rotates relative to the supporting body, the connecting rod can selectively move along the track wall to the track proximal end or the track distal end, thereby the connecting rod can move closer to or further away from the rotation axis, allowing the movable rod to move relative to the supporting body.

[0018] The opening and closing body has an opening and closing pivot hole communicating with the opening and closing track. The opening and closing pivot hole is adjacent to the near end of the track. The supporting body has a pivot rod that can pass through the opening and closing pivot hole and a pivot rod groove formed by the recess of the pivot rod. When the connecting rod moves towards the near end of the track through the rotating opening and closing body, the connecting rod will enter the interior of the pivot rod groove. When the connecting rod moves towards the far end of the track through the rotating opening and closing body, the connecting rod will leave the interior of the pivot rod groove. The opening and closing track is further provided with a track recess located between the near end of the track and the far end of the track. The track recess is used to accommodate a portion of the connecting rod, so that the connecting rod can temporarily stop moving inside the opening and closing track.

[0019] However, the adjustment mechanism further includes a return spring, which is disposed between the bearing body and the movable body and is capable of deformation, so that the return spring can generate a return force acting on the movable body, so that the linkage rod can continuously contact the track wall through the return force.

[0020] The adjustment mechanism further includes an adjustment body that can pass through the linkage rod and be helically engaged with the sling connection body, so that when the adjustment body rotates relative to the movable body, the sling connection body can selectively move closer to or further away from the movable body.

[0021] Finally, the linkage has a linkage member connected to the movable rod 321 and a wheel made of non-metallic material. The wheel is installed at the end of the linkage member and can contact the track wall to reduce the friction between the linkage and the opening / closing track.

[0022] The invention is characterized by the fact that the sling connection body of the adjustment mechanism is provided with a hook part and a contact part, and the sling of the resonant mechanism can be hooked onto the hook part by crossing the contact part from the resonant assembly of the resonant mechanism, so that the hooking space can accommodate part of the sling, while the other part of the sling can contact the contact part. In this way, the resonant mechanism and the sling connection body can be disassembled and assembled without any hand tools, which effectively simplifies the disassembly and assembly process between the resonant mechanism and the sling connection body. In addition, the user can quickly disassemble and detach the resonant mechanism from the sling connection body by hand. Furthermore, when the sling of the resonant mechanism is hooked onto the hook part each time, the tension of the resonant can be maintained within an appropriate range so that the snare drum can produce an ideal sound when it is struck, thereby effectively avoiding damage to the sound quality of the snare drum caused by excessive tension or looseness of the resonant.

[0023] Furthermore, the opening and closing body is pivotally connected to the supporting body, and the opening and closing body forms an opening and closing track through which the linkage rod of the movable body passes. This allows the opening and closing body to rotate relative to the supporting body, thereby driving the movable body to move along the track wall of the opening and closing track. In addition, the opening and closing track has a track recess between the near end and the far end of the track. When the linkage rod is located in the track recess, the track recess can accommodate a part of the linkage rod, allowing the linkage rod to temporarily stop moving inside the opening and closing track. This mechanism allows the opening and closing body to drive the movable body to move in multiple stages, allowing for various changes in the adhesion between the multiple snare wires of the snare wire mechanism and the lower drumhead of the snare drum. This not only effectively expands the range of snare drum timbre variations but also enhances the diversity of performance.

[0024] In addition, the rotating wheel of the linkage is made of non-metallic material, which makes the friction between the linkage and the opening and closing track significantly reduced when the rotating wheel contacts the track wall. As a result, the opening and closing body can smoothly drive the movable body to move, thereby reducing the risk of failure between the opening and closing body and the movable body.

[0025] However, the sling connection body mainly consists of a sling base, a sling connecting wheel, a sling pressure plate, pressure plate screws, and a connecting wheel connector. The pressure plate screws pass through the sling pressure plate to connect to the sling base, so that the sling pressure plate and the sling base can be clamped to the sheet sling. The sling connecting wheel is connected to the connecting wheel connector that is clamped by the sling pressure plate and the sling base. Thus, the sling connecting wheel can form a hook part 331 to be hooked by the rope sling. In this way, the sling connection body can be used for both rope slings and sheet slings, allowing the sling connection body to be flexibly matched with different types of slings.

[0026] Furthermore, the adjustment mechanism is equipped with a return spring between the supporting body and the movable body. The return spring can push the movable body so that the linkage rod of the movable body can continuously contact the track wall of the opening and closing track. This ensures that during the process of the opening and closing body driving the movable body to move and adjust the adhesion between the multiple strings of the string mechanism and the drumhead of the small drum, the opening and closing body can always maintain effective contact with the movable body, effectively avoiding jamming between the opening and closing body and the movable body, which would prevent the opening and closing body from driving the movable body to move.

Detailed Implementation

[0049] The present invention will be further described below with reference to specific embodiments and accompanying drawings, and the advantages and features of the present invention will become clearer with the description.

[0050] In this diagram, the two sides of the X-axis refer to the left and right sides when the performer strikes the snare drum 40, while the Y-axis refers to the front and back sides when the performer strikes the snare drum 40. The two sides of the Z-axis refer to the up and down sides when the performer strikes the snare drum 40. Furthermore, in this specification, directional terms such as "front," "back," "left," "right," "up," and "down" refer to the direction the performer is facing when striking the snare drum 40.

[0051] Please see Figure 2 and Figure 3 As shown, the resonant adjustment device 1 of the present invention is applied to a small drum 40. The resonant adjustment device 1 mainly consists of a resonant mechanism 10, a connecting mechanism 20, and an adjustment mechanism 30. As shown, the small drum 40 has a hollow, barrel-shaped drum shell 41. The upper and lower ends of the drum shell 41 are respectively provided with an upper opening 411 and a lower opening 412 spaced apart below the upper opening 411. Both the upper and lower openings 411 and 412 communicate with the internal space of the drum shell 41. The drum shell 41... An upper drum band 42 is installed at the upper opening 411, so that the upper drum band 42 can cover an upper drumhead 43 in the upper opening 411. A lower drum band 44 is installed at the lower opening 412 of the drum shell 41, which is spaced below the upper drum band 42, so that the lower drum band 44 can cover a lower drumhead 45 in the lower opening 412. In addition, multiple drum lugs 46 are provided between the upper drum band 42 and the lower drum band 44, which surround the outer periphery of the drum shell 41. The multiple drum lugs 46 are used to adjust the tension of the upper drumhead 43 and the tension of the lower drumhead 45.

[0052] Please see Figure 3 As shown, the snare mechanism 10 is located below the lower drumhead 45 of the snare drum 40. The snare mechanism 10 has two parts: a snare assembly 11 and two slings 12. The snare assembly 11 has a left snare connecting plate 111 and a right snare connecting plate 112 spaced apart to the right of the left snare connecting plate 111. The left snare connecting plate 111 is close to the left side of the drum shell 41 of the snare drum 40, while the right snare connecting plate 112 is close to the right side of the drum shell 41. Multiple snares 113 are connected between the left and right snare connecting plates 111 and 112, as shown in the figure. The two slings 12 are rope-like slings. One sling 12 is connected to the left snare connecting plate 111 and is designated as a left sling 121, while the other sling 12 is connected to the right snare connecting plate 112 and is designated as a right sling 122.

[0053] Please see Figure 3 and Figure 4As shown, the connecting mechanism 20 is connected to the outer periphery of the drum shell 41 of the small drum 40, and the connecting mechanism 20 is located on the left side of the drum shell 41. The connecting mechanism 20 has two parts: a fixed frame 21 and a movable frame 22. The fixed frame 21 is connected to the drum shell 41, and the movable frame 22 can be movably assembled to the fixed frame 21 along the Z-axis direction. The movable frame 22 has a movable rod 221 that passes through the inside of the fixed frame 21 and a movable seat 222 located outside the fixed frame 21. The lower end of the movable rod 221 is connected to the movable seat 222, so that the movable seat 222 is located below the fixed frame 21, and the movable seat 222 is recessed on the side facing the fixed frame 21. The moving seat 222 has two movable grooves 222a, and a movable hook 222b is formed on the side away from the drum shell 41. The moving seat 222 is provided with two movable grooves 222a and a movable hook 222b in sequence along the direction away from the drum shell 41. In this embodiment, the left sling 121 of the rattle mechanism 10 enters from the left rattle connecting plate 111 of the rattle assembly 11 into the interior of the movable groove 222a and hooks onto the movable hook 222b, so that a part of the left sling 121 is embedded in the movable hook 222b, while the other part of the left sling 121 can be located inside the movable groove 222a and contact the wall surface of the movable groove 222a.

[0054] Please see Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the adjustment mechanism 30 is located on the right side of the drum shell 41 of the small drum 40. The adjustment mechanism 30 mainly consists of a supporting body 31, a movable body 32, a sling connecting body 33, an opening and closing body 34, an adjustment body 35, and a return spring 36. In this embodiment, the supporting body 31 has a supporting fixing seat 311, a bearing sleeve 312, and a pivot member 313. The supporting fixing seat 311 is connected to the drum shell 41. The upper, right, and lower sides of the supporting fixing seat 311 respectively form an upper fixing opening 311a, a right fixing slot 311b, and a lower fixing opening 311c. All three openings—the upper fixing opening 311a, the right fixing slot 311b, and the lower fixing opening 311c—connect to a fixing space 311d located inside the supporting fixing seat 311. Furthermore, the bearing sleeve 312 is hollow, allowing a bearing to be formed inside the bearing sleeve 312. Space 312a, and bearing space 312a connects an upper bearing opening 312b located on the upper side of bearing sleeve 312, a right bearing slot 312c located on the right side of bearing sleeve 312, and a lower bearing opening 312d located on the lower side of bearing sleeve 312. The bearing sleeve 312 is located inside the fixed space 311d, such that the upper bearing opening 312b is located below the upper fixed opening 311a, and the right bearing slot 312c is located to the left of the right fixed slot 311b. The lower bearing opening 312d is located inside the lower fixed opening 311c, as shown in the figure. The pivot member 313 has a pivot plate 313a connected to the right side of the bearing fixing seat 311 and a pivot rod 313b extending from the pivot plate 313a. The pivot rod 313b is located above the right fixed slot 311b, and the pivot rod 313b is recessed from bottom to top to form a pivot rod groove 313c.

[0055] The movable body 32 of the adjustment mechanism 30 has a movable rod 321 parallel to the Z-axis and a connecting rod 322 parallel to the X-axis. The connecting rod 322 has a connecting member 322a connected to the central region of the movable rod 321, such that the connecting rods 322 are arranged intersectingly with the movable rod 321. A wheel 322b made of non-metallic material is installed at the end of the connecting member 322a away from the movable rod 321. The movable body 32 is movably assembled and movably connected to the support body 31 of the adjustment mechanism 30 along the Z-axis direction, so that the movable body 32 can be relative to the support body 31. 1. Moving along the Z-axis direction, in this embodiment, when the movable body 32 is movably connected to the bearing body 31, the movable rod 321 will pass through the bearing space 312a, so that the upper and lower ends of the movable rod 321 can be located outside the fixed space 311d of the bearing fixed seat 311 through the upper and lower bearing openings 312b and 312d of the bearing sleeve 312, and the linkage 322a will pass through the right fixed slot 311b of the bearing fixed seat 311, so that part of the linkage 322a and the entire rotating wheel 322b are located outside the fixed space 311d.

[0056] Please see Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the sling connecting body 33 of the adjusting mechanism 30 is connected to the lower end of the movable rod 321 of the movable body 32, so that the sling connecting body 33 can move synchronously with the movable body 32 of the adjusting mechanism 30 along the Z direction outside the fixed space 311d of the bearing fixed seat 311. Furthermore, the sling connecting body 33 is provided with a hook part 331 and a contact part 332 at different positions, and the hook part 331 forms a hooking space 331a, in which the right sling 122 of the wicking mechanism 10 can be hooked across the contact part 332 from the wicking assembly 11 of the wicking mechanism 10. At the hook portion 331, a portion of the right sling 122 is embedded inside the hooking space 331a, while the other portion of the right sling 122 can contact the contact portion 332. In this embodiment, the sling connecting body 33 has six parts: a sling base 333, a connecting guide post 334, a sling pressure plate 335, a pressure plate screw 336, a connecting wheel connector 337, and a sling connecting wheel 338. The sling base 333 is located below the bearing fixing seat 311, and the sling base 333 has a first fixing seat surface located on the right side of the sling base 333 in sequence from the rightmost side. The first turning surface 333a and the second fixing surface 333b located on the upper side of the sling base 333 are connected by a first turning surface 333a and a second fixing surface 333f. In this embodiment, the first fixing surface 333a is inclined, while the second fixing surface 333b is horizontal, as shown in the figure. The sling base 333 is recessed to form two connecting grooves 333c arranged at intervals. The connecting grooves 333c are formed on the first turning surface 333a, the second fixing surface 333b, and the second turning surface 333f. The connecting grooves 333c have... A groove bottom surface 333d is spaced below the second fixed seat surface 333b. The connecting groove 333c has a first turning surface 333e adjacent to the first fixed seat surface 333a on one side of the groove bottom surface 333d, and a second turning surface 333f on the side of the groove bottom surface 333d away from the first turning surface 333e. The connecting guide post 334 is connected to the second fixed seat surface 333b of the sling base 333, so that the connecting guide post 334 is located between the two connecting grooves 333c. The connecting guide post 334 is inserted into the movable rod 321 of the movable body 32.

[0057] Please see Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the sling pressure plate 335 of the sling connecting body 33 contacts the first fixed seat surface 333a of the sling base 333. The sling pressure plate 335 has a recess on the side facing the sling base 333, forming a pressure plate space 335a between two connecting grooves 333c. Each pressure plate screw 336 of the sling connecting body 33 has a screw shank 336a and a screw head 336b with a profile larger than the screw shank 336a. The screw shank 336a passes through the sling... The pressure plate 335 is spirally fitted into the sling base 333, allowing the screw head 336b to contact the pressure plate 335 so that the screw head 336b and the sling base 333 are clamped together in the pressure plate 335. Additionally, the connecting wheel connector 337 has a connecting head 337a located inside the pressure plate space 335a and a connecting rod portion 337b with a smaller profile than the connecting head 337a. The connecting rod portion 337b extends from one end of the connecting head 337a into the pressure plate space 335a. The outer part of 35a is such that a portion of the connecting rod portion 337b is located outside the pressure plate space 335a. A portion of the sling connecting wheel 338 is positioned close to the sling base 333 as a connecting wheel axle portion 338a, while the remaining portion of the sling connecting wheel 338 is positioned away from the sling base 333 as a connecting wheel portion 338b with a profile larger than the connecting wheel axle portion 338a. The connecting wheel axle portion 338a is connected to the connecting rod portion 337b, such that the sling connecting wheel 338 is located at the bottom of the sling. Between the two connecting grooves 333c of the seat 333, the height of the sling connecting wheel 338 at its highest point is lower than the height of the connecting grooves 333c. In this embodiment, the two connecting grooves 333c form the contact portion 332 of the sling connecting body 33, and a hooking space 331a for the hook portion 331 is formed between the connecting wheel axle portion 338a and the connecting wheel portion 338b, so that the sling connecting wheel 338 forms the hook portion 331 of the sling connecting body 33. Figure 10 As shown, when the right sling 122 of the sling mechanism 10 can cross the contact portion 332 from the sling assembly 11 of the sling mechanism 10 and hook onto the hook portion 331, a part of the right sling 122 is located between the connecting wheel axle portion 338a and the connecting wheel portion 338b, while the other part of the right sling 122 is located inside the connecting groove 333c to contact the wall surface of the connecting groove 333c. At the same time, different positions of the right sling 122 will contact the first and second turning surfaces 333e and 333f of the sling base 333, respectively, so that the right sling 122 forms a first bend 122a and a second bend 122b spaced apart from each other. As shown in the figure, the first bend 122a contacts the first turning surface 333e and is adjacent to one side of the connecting groove 333c, while the second bend 122b contacts the second turning surface 333f and is adjacent to the other side of the connecting groove 333c.

[0058] Please see Figure 6 , Figure 7 , Figure 8 and Figure 11 As shown, the opening / closing body 34 of the adjusting mechanism 30 is pivotally connected to the supporting body 31 of the adjusting mechanism 30, so that the opening / closing body 34 can rotate relative to the supporting body 31 about a rotation axis L parallel to the X-axis. The rotating opening / closing body 34 drives the movable body 32 to move. As shown in the figure, the opening / closing body 34 has two parts: an opening / closing turntable 341 and an opening / closing cover 342. An opening / closing track 341a is recessed on one side of the opening / closing turntable 341. The opening / closing turntable 341 extends from the opening / closing track 341a along the rotation axis L to form an opening / closing pivot hole 341b communicating with the opening / closing track 341a. The opposite sides of the opening / closing track 341a are respectively provided as a track proximal end 341c and a track distal end 341d. The opening / closing track 341a forms from the track proximal end 341c toward the track distal end 341d. A curved track wall 341e is provided, and the opening and closing track 341a is recessed at the position of the track wall 341e to form a track notch 341f located between the near end 341c and the far end 341d of the track. In this embodiment, the opening and closing turntable 341 is fitted onto the pivot rod 313b of the supporting body 31, so that the pivot rod 313b passes through the opening and closing pivot hole 341b from the opening and closing track 341a, allowing the opening and closing turntable 341 to be pivotally connected to the pivot rod 313b. At the same time, the wheel 322b of the connecting rod 322 penetrates into the interior of the opening and closing track 341a to contact the track wall 341e of the opening and closing track 341a, so that the friction between the connecting rod 322 and the opening and closing track 341a can be effectively reduced. The opening and closing cover 342 is locked to the pivot rod 313b to prevent the opening and closing turntable 341 from disengaging from the pivot rod 313b.

[0059] Please see Figure 6 , Figure 7 and Figure 8As shown, the adjusting body 35 of the adjusting mechanism 30 passes through the upper fixed opening 311a of the supporting body 31 and into the movable rod 321 of the movable body 32, allowing the adjusting body 35 to rotate relative to the supporting body 31. The adjusting body 35, located inside the movable rod 321, is helically engaged with the connecting guide post 334 of the connecting body. Therefore, when the adjusting body 35 rotates relative to the movable body 32, the sling connecting body 33 can selectively move closer to or further away from the movable body 32. Furthermore, the return spring 36 of the adjusting mechanism 30 is located inside the bearing sleeve 312 of the supporting body, and... One end of the return spring 36 abuts against the inner wall of the bearing fixed seat 311, while the other end of the return spring 36 abuts against the linkage member 322a of the linkage rod 322, so that the return spring 36 is disposed between the bearing body 31 and the movable body 32. When the return spring 36 is located between the bearing body 31 and the movable body 32, the return spring 36 can deform, and the deformed return spring 36 can generate a reset force F acting on the movable body 32, so that the wheel 322b of the linkage rod 322 can continuously contact the track wall 341e of the opening and closing track 341a through the reset force F.

[0060] Please see Figure 12A , Figure 12B , Figure 12C , Figure 12D , Figure 12E and Figure 12F As shown, to illustrate a specific application of adjusting the adhesion between the lower drumhead 45 of the snare drum 40 and the multiple lead wires 113 of the lead wire mechanism 10, firstly, as... Figure 12A and Figure 12B As shown, the wheel 322b of the linkage 322 contacts the track remote 341d of the opening and closing track 341a through the reset force F of the reset spring 36, so that the linkage 322 is away from the opening and closing pivot hole 341b of the opening and closing turntable 341. As a result, the linkage 322 will be located at the lower end of the right fixed slot 311b of the bearing fixed seat 311, so that the adhesion of the multiple sound wires 113 to the lower drum skin 45 can be minimized. Therefore, when the upper drum skin 43 of the snare drum 40 is struck, the vibration of the multiple sound wires 113 can be weakened, which can relatively increase the duration of the sound wires 113.

[0061] like Figure 12C and Figure 12DAs shown, the opening / closing turntable 341 of the opening / closing body 34 rotates counterclockwise, causing the rotating wheel 322b of the connecting rod 322 to move along the track wall 341e of the opening / closing track 341a inside the track 341a. As the rotating wheel 322b moves, it gradually approaches the opening / closing pivot hole 341b of the opening / closing turntable 341. During the movement of the rotating wheel 322b along the track wall 341e, the movable body 32 of the adjusting mechanism 30 and the sling connecting body 33 of the adjusting mechanism 30 move synchronously towards the track wall. The upward movement tightens the multiple resonant wires 113 of the resonant wire mechanism 10, thereby increasing the adhesion between the lower drum skin 45 of the adjusting snare drum 40 and the multiple resonant wires 113 of the resonant wire mechanism 10, further enhancing the resonance effect of the resonant wires 113. When the rotating wheel 322b is aligned with the track recess 341f located in the opening and closing track 341a, a portion of the rotating wheel 322b will enter the interior of the track recess 341f, allowing the track recess 341f to accommodate a portion of the connecting rod 322 so that the connecting rod 322 can temporarily stop moving inside the opening and closing track 341a.

[0062] like Figure 12E and Figure 12F As shown, the opening and closing turntable 341 of the opening and closing body 34 continues to rotate counterclockwise, causing the wheel 322b of the linkage 322 to move along the track wall 341e of the opening and closing track 341a from the track recess 341f toward the track remote 341d of the opening and closing track 341a. As a result, the linkage 322 will gradually approach the uppermost end of the right fixed slot 311b of the bearing fixed seat 311, and thus the linkage 322 will enter the pivot groove 313c of the pivot rod 313b. When the wheel 322b is located at the track remote 341d, the movable body 32 will stop moving relative to the bearing body 31, thereby maximizing the tightness of the multiple resonant wires 113 and maximizing the adhesion between the multiple resonant wires 113 and the lower drumhead 45. Thus, when the upper drumhead 43 of the snare drum 40 is struck, the vibration of the multiple resonant wires 113 can be enhanced.

[0063] like Figure 12G and Figure 12HAs shown, the opening and closing turntable 341 of the opening and closing body 34 rotates clockwise, causing the wheel 322b of the linkage 322 to move along the track wall 341e of the opening and closing track 341a from the near end 341c of the track towards the far end of the track. As a result, the linkage 322 gradually approaches the lower end of the right fixed slot 311b of the bearing fixed seat 311, and the linkage 322 moves away from the pivot groove 313c of the pivot rod 313b. When the wheel 322b is located at the near end 341c of the track, the movable body 32 stops moving relative to the bearing body 31, thereby reducing the adhesion between the lower drum skin 45 and the multiple sounding wires 113.

[0064] The above description is illustrative only and not restrictive to the present invention. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope of the technical concept, and all such modifications, variations or equivalents will fall within the protection scope of the present invention.
