Abstract
A method of making an acoustic assembly for use in a transducer includes forming a multi-layer assembly. The multi-layer assembly includes a first layer member and a second layer member. Each member includes a center portion, an edge portion and an aperture separating the center portion and the edge portion. The assembly has an assembly stiffness that is greater than the stiffness of either the first or second layer members. A hinge joins the assembled first and second center portions and the first and second edge portions such that the assembled first and second center portions is free to at least partially rotate relative to the assembled first and second edge portions about an axis. A flexible layer member is coupled to the assembly and provides airtight sealing of the passageway.
