Abstract
A protective cover assembly is disclosed that includes a membrane and a layered assembly bonded to the membrane. The membrane is positioned in an acoustic pathway and has a first side and a second side, the first side facing toward an acoustic cavity and the second side of the membrane facing toward an opening of the acoustic pathway. The layered assembly includes at least one curable support layer bonded to a side of the membrane formed of a polymer adhesive and defining at least a portion of a wall for the acoustic pathway.
Claims19
An assembly comprising:
- a membrane in an acoustic pathway,
- wherein the membrane comprises:
- a first side, wherein the first side faces toward an acoustic cavity;
- and
- a second side, wherein the second side of the membrane faces toward an opening of the acoustic pathway;
- and
- at least one layered assembly, wherein the at least one layered assembly is bonded to one of the first side of the membrane or the second side of the membrane along a periphery of the first side of the membrane or the second side of the membrane,
- wherein the at least one layered assembly comprises:
- a curable support layer;
- and
- a first external adhesive,
- wherein the first external adhesive is bonded to the curable support layer;
- and
- a second external adhesive,
- wherein the second external adhesive is bonded to the membrane;
