Abstract
A sound-transmissive cover assembly which provides protection from the ambient environment to transducers such as microphones, loudspeakers, buzzers, ringers, and other delicate devices; and across which sound energy can pass with very low attenuation. The cover assembly has a protective membrane layer and a porous support material layer which are selectively bonded together at least in the outer region near their edges. An inner unbonded region surrounded by the bonded outer region is provided so that the protective membrane and porous support layer can vibrate or move independently in response to acoustic energy passing through them. An embodiment of the assembly includes at least one acoustic gasket attached to one or both of the layers so as to not impede independent movement of the layers.
