Abstract
The diaphragm of the electroacoustic transducer is made of a material in which fibers having at least two different radii taken out of wood are mixed together. Two mean radii A and B, among different mean radii of the fibers are set to satisfy the relationship: 0.5.times.A.ltoreq.B.ltoreq.0.5.times.A. By utilizing such a diaphragm, the balance of the density, rigidity, and internal loss of the diaphragm can be improved, and thus the acoustic characteristics of the electroacoustic transducer such as a speaker unit can be improved.
