A new method of measuring the dynamic elastic modulus of paper for loudspeaker
  
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.
