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.
Claims15
A video monitor microphone assembly comprising:
- a video monitor having a housing having at least two microphone ports and an interior cavity containing electronic components emitting electromagnetic interference;
- a directional microphone 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;
- and
- a shroud 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, the shroud includes at least two acoustic ports, each of the acoustic ports being aligned with one of the microphone ports of the video housing.
