[0017] The technical solution of the utility model is further described below through embodiments and in conjunction with the accompanying drawings.

[0018] Example:

[0019] This embodiment provides a drum cavity tuning mechanism, such as Figures 1 to 3 As shown, it includes a silent surface 1, a lifting frame and an adjusting rod. The silent surface 1 is arranged in the drum cavity and is located below the drum surface 18. The silent surface is provided with a plurality of hollows and a plurality of reinforcing ribs. A circle of through holes 2 is also provided on the edge of the silent surface. A plurality of reset mechanisms are provided on the inner wall of the drum shell 14. The reset mechanisms extend into the through holes 2. The lifting frame is fixedly connected to the center of the silent surface, and the adjusting rod passes through the drum shell and the lifting frame.

[0020] The lifting frame includes a fixed plate 11 and two adjusting handles. The fixed plate 11 is fixedly connected to the silent surface 1 by bolts. A vertical plate 12 is provided on each side of the fixed plate 11. A slide groove 13 is provided on the vertical plate 12. The adjusting handle includes a rod body 9 and a support arm 10 provided at both ends of the rod body. The first end of the support arm 10 is rotatably connected to the rod body 9, and the second end of the support arm 10 is provided with a sliding column. The support arms on the same side of the two adjusting handles are cross-rotatably connected, and the sliding columns of the support arms on the same side of the two adjusting handles are slidably arranged in the same slide groove. The adjusting rod passes through the rod bodies of the two adjusting handles in sequence and is threadedly connected to the rod bodies.

[0021] The adjusting rod includes an adjusting portion 6, a screw 3 and two fixing seats. The adjusting portion is arranged at one end of the screw, the fixing seat is arranged on the side wall of the drum shell 14, and the screw is rotatably arranged between the two fixing seats. The screw is symmetrically provided with a first thread 4 and a second thread 5. The first thread and the second thread have opposite rotation directions and are distributed and threadedly connected with the rod bodies in the two adjusting handles. When the screw is rotated by the adjusting portion, the rod bodies of the two adjusting handles move closer to or farther from each other, thereby making the sliding columns of the same-side arms of the two adjusting handles move closer to or farther from each other, so that the silent surface moves closer to or farther from the drum surface, thereby adjusting the vibration amplitude of the drum surface to achieve the purpose of adjusting the drum volume.

[0022] The reset mechanism includes a fixing frame 15, a limiting rod 16 and a spring 17. The fixing frame 15 is fixedly connected to the drum shell 14. The limiting rod 16 is fixedly arranged on the fixing frame 15 and extends into the through hole 2. The spring 17 is sleeved on the limiting rod 16 and is located between the fixing frame 15 and the silent surface 1. The reset mechanism is used to provide elastic force to the edge of the silent surface when the silent surface rises, ensuring that the silent surface can move upward as a whole, so that all parts of the silent surface can be close to the drum surface.

[0023] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
