What is carbon fiber diaphragm? A new generation of expensive diaphragm closer to the sky high diamond diaphragm As the name suggests, it is a horn unit diaphragm made of carbon fiber. The ideal diaphragm needs to have the characteristics of light weight, large Young's modulus, pleasant damping and small split vibration. The key point is that the forward and backward delay of vibration should be appropriate. Carbon fiber material, with molecular structure similar to diamond, has high rigidity,...
