Kind Code:
A1
Abstract:
A diaphragm having a gentle wave shape formed on a pressure receiving face of a partition plate of the diaphragm, where the wave shape is formed in the radial and circumferential directions of the diaphragm. Stress caused by load can be effectively relieved not only through elasticity of material, but also through deformation that is increased in proportion to pressure induced mainly by bending.
