[0002] In the world of music, beats are the cornerstone of melodies. To help music learners better master beats, metronomes came into being. The origin of metronomes can be traced back to the 16th century, when they were mainly used to train choirs to master accurate rhythms. Over time, the functions and forms of metronomes have evolved continuously, but their core purpose has always remained the same, which is to provide a stable beat reference for music learners.

[0003] Metronomes play a crucial role in modern music education. Whether beginners or professional musicians need to use metronomes to practice rhythm sense. It helps students establish a sense of time with regular and constant rhythms, and then master the rhythm of music. However, there are still some inconveniences in the actual use of existing metronomes. For example, most metronomes need to be manually wound up to start. Once the spring stops, it needs to be wound up again, which is undoubtedly a trouble for users. In addition, the sound and volume of the beat swing of existing metronomes are fixed and cannot be adjusted according to the actual use environment. Summary of the Invention
