Abstract

PURPOSE:To obtain the thin film by forming the coating layer of the aluminum, titanium or the like on the disphragm substrate and then to obtain the multilayer film diaphragm featuring a high mechanical intensity by forming the coating layer of the berylium and boron over the thin film. CONSTITUTION:The thin plate of the copper, silver, etc. is formed into a domed shape to obtain diaphragm substrate 1. The material of the aluminum, titanium, etc. is coated in an optional thickness onto the concave surface of substrate 1 through the vacuum evaporation or other methods to obtain film 2. After this, the material such as the berylium, boron, etc. featuring a large Young's midulus and low density is coated onto the surface of film 2 through the vacuum evaporation or other methods to obtain layer 3. Then only substrate 1 is dissolved away through the etching or other methods to obtain multilayer film diaphragm 4. Thus a diaphragm featuring the increased mechanical intensity can be obtained.
