Description

Technical Field

[0001] This utility model relates to the technical field of accordion accessories, specifically an accordion adjustable strap. Background Technology

[0002] The accordion is a keyboard instrument that, through its bellows, reeds, and keyboard, produces a clear, bright, full, and even sound with a mellow, delicate, and richly varied tone. The accordion can not only play beautiful monophonic melodies but also polyphonic pieces and, like the piano, can play rich harmonies with both hands. During performance, the accordion is carried on the chest of the player using a strap. However, existing accordion straps lack anti-slip components, making it difficult to keep the two straps close together, especially for players with narrow shoulders. The straps are prone to slipping off at the shoulders, affecting the reliability of the instrument. Therefore, we propose an adjustable accordion strap to solve these problems. Utility Model Content
