Claims
- 1. A method for mounting a diaphragm in an electroacoustical transducer assembly of the type having a housing member with an opening therein, an electrostatic vibratile diaphragm formed of a pliant, relatively inelastic material having a conductive and a nonconductive surface, a substantially inflexible backplate member having a grooved surface and a spring, comprising the steps of;
- placing said diaphragm adjacent said housing member such that said diaphragm extends across said housing member opening;
- applying uniform, radially outward forces to said diaphragm for the purpose of temporarily maintaining at least the inner region of said diaphragm in a generally wrinkle-free planar orientation;
- placing the grooved surface of said backplate member in contact with an inner region of the insulative surface of said diaphragm;
- applying a force to said backplate member, in excess of said radial forces on said diaphragm, for the purpose of offsetting said inner diaphragm region from its said planar orientation to thereby increase the total amount of said diaphragm extending across said housing opening over that extending across said housing opening before the application of said inner region offsetting force, said offsetting force overcoming said radial forces, thereby enabling additional amounts of said diaphragm to move uniformly inward as said inner diaphragm region is being so offset;
- securing an outer region of said diaphragm in a fixed position with respect to said housing member while said inner diaphragm region is in its said offset condition; and
- inserting said spring into said assembly such that portions of said spring are reacted against said housing member and a portion of said spring presses on said backplate member to maintain said grooved portion of said backplate in contact with a portion of said offset inner diaphragm region.
