Abstract
Disclosed herein is an acoustic diaphragm for converting electrical signals into mechanical signals to produce sounds. The acoustic diaphragm comprises carbon nanotubes or graphite nanofibers as major materials. Preferably, the carbon nanotubes or graphite nanofibers are included or dispersed in the acoustic diaphragm. Since the acoustic diaphragm has excellent physical properties in terms of elastic modulus, internal loss and strength, it can effectively achieve superior sound quality and high output in a particular frequency band as well as in a broad frequency band.
