HYBRID ACOUSTIC EMI FOAM FOR USE IN A PERSONAL COMPUTER

摘要

The described embodiments relate to an electronic assembly that includes multiple varied electrical components. In some embodiments, the electronic assembly can include electrical components susceptible to electromagnetic interference (EMI). In one particular embodiment, an antenna can be positioned along an exterior surface of an enclosure of the electronic assembly and another electrical component can be disposed within the enclosure. When the other electrical component is a speaker component, a port or opening for emitting audio output can be protected from EMI by surrounding the port with a conductive gasket that includes a closed cell foam substrate wrapped in an electrically conductive fabric. In some embodiments, the closed cell foam substrate defines a number of perforations that are plated with an electrically conductive material.

主权项

1. An audio assembly, comprising:
an assembly housing defining an interior volume and comprising an audio port that opens to an audio transducer; a gasket comprising an electrically conductive material, the gasket surrounding the audio port; and an antenna disposed along a wall of the assembly housing, wherein the gasket blocks electromagnetic interference (EMI) emitted by the antenna from passing through the gasket and entering the audio port.
