With the diversification of musical arts and the increasing pursuit of higher quality instruments, modern music lovers not only focus on the hand drum's performance capabilities but also place comprehensive demands on its sound quality, durability, and portability.

[0003] Although improved hand drums using composite materials or special structural designs have emerged in the market in an attempt to meet these needs, many limitations still exist in practical applications. Some hand drums using composite materials suffer from poor compatibility between material properties and acoustic principles, resulting in a dry tone and insufficient resonance, making it difficult to reproduce the rich and full sound of traditional hand drums. While hand drums with special structural designs optimize tone to some extent, they are less durable; after prolonged use, structural connections are prone to loosening and deformation, affecting playing stability. Furthermore, these improved hand drums often neglect the balance between portability and durability in their pursuit of functional innovation, resulting in instruments that are too large or whose materials are not wear-resistant. To address these issues, this utility model provides a mini multi-functional hand drum to solve the aforementioned problems. Utility Model Content
