摘要:
An electroacoustic transducer diaphragm is a multi-layered one which includes an intermediate diaphragm layer formed between a first surface layer and a second surface layer. The first and second surface layers are formed of a woven fabric and are formed in one piece with the fiber axial orientations of the first and second surface layers being shifted by a specified angle. Preferably, the first and second surface layers made of a biaxial woven fabric are formed with their fiber axial orientations being shifted by about 45 degrees. Thus, the multi-layered electroacoustic transducer diaphragm having surface diaphragm layers formed of the woven fabric is provided in order to reduce deformation and distortion, thereby producing a high-quality multi-layered diaphragm.
