Diaphragm of electroacoustic transducer and method of manufacturing the same

摘要

A diaphragm of an electroacoustic transducer is made of a material including fibers taken out of young stems of bamboo grasses and preferably, used as the material is paper made by mixing the fibers taken out of young stems of bamboo grasses and wood pulp in a predetermined ratio. Containing fibers taken out of young stems of bamboo grasses allows rigidity and internal loss characteristics of the diaphragm to be enhanced without increasing its density, thereby expanding a frequency band of the diaphragm. In addition, young stems of bamboo grasses can be gathered without affecting parent bamboo grasses, which prevents destruction of the environment.
