ABSTRACT:
A video monitor assembly incorporating a microphone shielded from electromagnetic interference emitted by the monitor's electronic components. The assembly includes a video monitor having a housing with a microphone port and an interior cavity containing electronic components emitting electromagnetic interference. A microphone is mounted within the housing, the microphone being capable of detecting at least a portion of the electromagnetic interference emitted by the electronic components of the monitor. A shroud is secured within the housing, the shroud being made from an electromagnetic interference shielding material and at least partially surrounding the microphone to substantially reduce the microphone's detection of the electromagnetic interference emitted by the electronic components of the monitor.
