  • Thermal wind shield and associated methods
    Patent number: 10893350
    Abstract: A virtual reality apparatus comprising: at least one heat-generating virtual reality electronic component; a housing configured to contain the at least one heat-generating virtual reality electronic component; a microphone having an audio input positioned at a surface of the housing; and a plurality of elongated heat-conducting elements configured to conduct heat generated by the at least one heat-generating virtual reality electronic component from the inside of the housing to the outside of the housing, wherein the plurality of elongated heat-conducting elements protrude from the surface of the housing in proximity to the audio input of the microphone to disturb the flow of air at the surface and reduce the amount of wind noise detected by the microphone.
    Type: Grant
