摘　　要：由于组成ECM的零部件的材质和这些零部件在制造过程中工艺特性的不同,使ECM组装后的电声特性受到了较显著的影响。分别对组成ECM的背极材料、振膜材料进行了较为详细的讨论,这种讨论对ECM的生产是有指导意义的。Because the materials of ECM parts and technologies in production are different, the electroacoustie characteristic of ECM that have been packaged are outstandingly influenced. Detailed discussions on material of electreted-board and diaphragm are discussed, and the study will be a instruction to the process of producing ECM.
