Abstract

PURPOSE:To obtain a loudspeaker having a small distortion factor and with a high resonance frequency by coating a diaphragm base material surface for the loudspeaker with an amorphous diamond by the method for disposing an electron cyclotron resonance plasma chemical vapor. CONSTITUTION:Moldings to which the diaphragm base material surface for the loudspeaker such as a high polymer film and a metallic thin film is coated with the amorphous diamond by the electron cyclotron resonance plasma chemical vapor deposition method are used as diaphragms. Thus, since the diaphragm raw material for the loudspeaker is coated with the amorphous diamond having a high elastic modulus, a bending rigidity is very large, and during a vibration, the diaphragm is not deformed, a split resonance does not occur, and the loudspeaker having excellent sound pressure-frequency characteristics, distortion factor, and phase characteristics can be obtained.
