| titleOfInvention | Manufacturing method of acoustic diaphragm |
| abstract | (57) [Problem] For example, an acoustic diaphragm having good reproduction characteristics in a high sound range when used for a speaker can be manufactured at low cost and in a complicated shape. SOLUTION: A molding step of molding titanium metal into an acoustic diaphragm shape to obtain a titanium diaphragm, and a ceramicizing step of heat-treating the titanium diaphragm to make the entire titanium diaphragm a titanium oxide.
