AI Technical Summary

Technical Problem

When adjusting the pitch of the existing timpan drum, the drum skin is prone to slight relaxation, resulting in inaccurate pronunciation, and the adjustment takes a long time, making it difficult to fine-tune the tension or relaxation of the drum skin.

Method used

A fine-tuning structure of the timpan drum is designed, including a lever assembly and a manual adjustment assembly. By rotating the adjustment stud and adjustment screw holes, the long side plate is driven to move up or down, driving the movement of the connecting assembly and the drum piping plate to achieve fine-tuning of pitch.

Benefits of technology

Accurate fine-tuning of the tightness of the drum skin is achieved, which shortens the adjustment time, improves the musical quality of the playing, and avoids the drum skin pulling discs being stuck after adjustment.

Abstract

The utility model discloses a fine tuning structure of a timpani, which is provided with a lever assembly and a manual tuning assembly, the lever assembly comprises a central pillar arranged at the top end of a base and a long side plate with a first end and a second end, and the manual tuning assembly comprises an adjusting stud, an adjusting screw hole and an adjusting block. The second end of the long side plate is driven to move upwards or downwards under the matching action of the adjusting screw hole, the connecting assembly at the first end is driven to move downwards or upwards, the purpose of driving the drum head pull disc to move upwards or downwards is further achieved, and the adjusting effect is achieved. According to the utility model, the adjustment can be carried out by rotating the adjusting stud, and the rotation angle of the long side plate is small due to the screw-thread fit, i.e., the movement distance of the drum head pull disc is short, thereby realizing the fine adjustment of the drum head pull disc by a player, and further achieving the purpose of fine adjustment of the tightening degree of the drum head.
