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, achieves balance between internal resistance and acoustic conductivity, analyzes and transmits details accurately, neatly and naturally. Compared with the beryllium metal of the well-known high-end speaker, the density of carbon fiber is similar to that of metal beryllium. The young’s coefficient is 1.4 times that of beryllium, and the acoustic conductivitv is 1.5 times that of beryllium. Therefore, it vibrates immediately when the signal is received and stops immediately when the signal disappears. Carbon fiber diaphragm achieves a balance between acoustic conductivity and internal resistance, that is, it has ideal forward and backward performance, high sensitivity and excellent transient response, and can more accurately restore the essence of sound.
