Abstract
The present invention discloses a diaphragm for a speaker including a lower surface area, a central area formed on said lower surface area, an upper surface area formed on said central area. The upper surface area, the central area and the lower surface area includes homogeneous amorphous materials. The diaphragm includes internal stress changing with a depth from the surface to the center of the diaphragm.
