Abstract
An acoustic damper for covering a housing inlet of a transducer is disclosed. The damper includes a mesh panel and a non-mesh periphery. The non-mesh periphery of the damper is adhesively attached to the housing of the transducer wherein the mesh panel covers the inlet. The non-mesh periphery of the damper inhibits the adhesive from wicking into the mesh panel. The damper is adaptable for attachment of a film. The film is capable of cooperating with a backplate to form a motor assembly of the transducer.
