| 中文摘要: |
| 本文从理论上对末端有负载的悬臂梁的自由振动频率进行了计算，并采用新的激振和抬振装置，建立一种扬声器纸盆材料的动态弹性模量的新测量方法，测量了若干纸盆试样，得出典型的幅频响应曲线，并对实验结果进行了分析． |
| 英文摘要: |
| A theory is developed to calculate the inherent frequence of a cantilever with attached mass at the free end. At the same time, a new apparatus for activating and sensing of vibration is designed to measure the dynamic young’s modulus of paper for the paper basin of a loudspeaker. Some test papers have been measured and typicalamplitude-frequency response curves acquired and analysed. |
