    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 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.

    Abstract: A diaphragm for a speaker and a speaker device, a frequency characteristic as well as the endurance against input of which are improved, have been provided. A convexo-concave portion (10) is radially formed at a neck of the diaphragm (12), which is stuck to a voice coil bobbin (11), to increase an adhesion area of the neck itself, thereby the endurance against input is improved. In addition, the neck is stuck to the voice coil bobbin by an adhesive (13) to increase the mechanical strength of the neck itself, thereby a frequency characteristic as well as the endurance against input are improved.
