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 reinforcing agents. Preferably, the carbon nanotubes or graphite nanofibers are included or dispersed in the acoustic diaphragm or coated on the surface of the acoustic diaphragm. Since the acoustic diaphragm has excellent physical properties in terms of elastic modulus, internal loss, strength and density, it can effectively achieve superior sound quality and a high output in a particular frequency band as well as in a broad frequency band.
