| Abstract: | The research works on loudspeaker vibration films and their developments were reviewed. Especially reviewed the diaphragms made by Diamond Film (DF) and Diamond Like Carbon (DLC). The methods and techniques for the preparation of diaphragms on tweeter made by DF material and DF-Ti multiple layer material were discussed. We prepared several DF-Ti diaphragms by the method of DC Arc Plasma Jet CVD. Their acoustic characters were remarkably improved. |
