Acoustic oscillatory plate producing method e.g. for use in loudspeaker involves heat processing titanium oscillatory plate during ceramic formation to change titanium oscillatory plate into titanium oxide
Acoustic oscillatory plate producing method e.g. for use in loudspeaker involves heat processing titanium oscillatory plate during ceramic formation to change titanium oscillatory plate into titanium oxide
The titanium metal plate is shaped to form a titanium oscillatory plate (1). The titanium oscillatory plate is subjected to heat processing at 880 deg C or more during ceramic formation, to change titanium oscillatory plate into titanium oxide. An Independent claim is also included for acoustic oscillatory plate.
