摘　　要：利用智能手机探索乐器的物理规律,既有趣味性又有科学性。为了研究吉他弦线振动规律,文章基于智能手机和移动应用程序(Phyphox)设计实验方案,通过定量测量吉他弦线品距、直径和振动频率,证实了吉他弦线振动规律,结果表明该方法具有较高可行性和有效性。该研究有助于理解吉他弦线振动物理规律和吉他发声原理,研究体现了“从生活走向物理,从物理走向社会”的思想。Using smartphones to explore the physical laws of musical instruments is both interesting and scientific.In order to explore the vibration law of guitar strings,it designs an experimental scheme based on smartphones and mobile applications(Phyphox).By quantitatively measuring the distance,diameter and vibration frequency of guitar strings,the experimental results confirm the vibration law of guitar strings,and the results show that the method is highly feasible and effective.The research is helpful to understand the physical law of guitar string vibration and the principle of guitar sound.The research project reflects the idea of“from life to physics,from physics to society”.
