  • Composite multilayer filtering construction for use as a subcomponent in acoustic and electronic products in general
    Patent number: 10993008
    Abstract: A composite multilayer filtering construction for use in filtering applications requiring a high filtering efficiency for particles of the order of microns and a high permeability of the filtering medium, and for use as a sub-component within acoustic and electronic products, in particular microphones and speakers, comprises at least a first layer of polymeric nanoporous membrane and at least a second layer of a synthetic monofilament precision fabric, the first polymeric nanoporous membrane layer being coupled to the second precision fabric layer thereby providing an integral filtering medium adapted to prevent a passage therethrough of particles even of 1-2 ?m and of pressurized liquids.
    Type: Grant
    Filed: May 24, 2016
    Date of Patent: April 27, 2021
    Assignee: SAATI S.P.A.
