Abstract: |
A head mounted display in a video/audio system includes a display device, a head mount, noise reduction devices, and a speaker. The display device is coupled to the head mount and produces visual images based on received video signals. The head mount is mounted on the user's head and is coupled to the noise reduction devices, which cover the user's ears such that external noise is reduced. The noise reduction devices are coupled together via a strap that fits around the user head. The noise reduction devices are coupled to and house speakers that produce sound signals based on received audio signals. As a result, the user may see the video images produced by the display device and clearly hear the sounds produced by the speaker, and the external noise heard by the user is reduced.
