NOISE MITIGATION FOR HEAD-MOUNTED DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18225036 titled 'NOISE MITIGATION FOR HEAD-MOUNTED DEVICE
Simplified Explanation
- The patent application describes a head-mounted device that effectively manages heat and reduces noise output. - The device includes a support member that extends across a flow channel and has multiple sections with different profiles and/or cross-sectional dimensions. - These different sections generate tonal noises at different frequencies, which helps mask the tonal noises among the broadband noises generated by the device. - The support member can be moved within the flow channel and is rigidly coupled to other components of the head-mounted device. - Additionally, the support member can draw heat away from other components of the device and dissipate it through the flow of air within the flow channel.
Original Abstract Submitted
A head-mounted device can effectively manage heat while also managing noise output in a manner that reduces the user's perception thereof. For example, a support member extending across a flow channel can provide multiple sections with different profiles and/or cross-sectional dimensions within the flow channel. Each of the profiles and/or cross-sectional dimensions can generate tonal noises at different frequencies, so that the tonal noises generated are distributed across multiple frequencies to mask such tonal noises among broadband noises that are generated by the head-mounted device. Such a support member can be moveably positioned within the flow channel and rigidly coupled to other components of the head-mounted device. Such a support member can also be used to draw heat away from other components of the head-mounted device to be dissipated by the flow of air within the flow channel.
