    Abstract: A head-mountable device can include an outer frame that can define a first opening, a second opening an internal volume between the first opening and the second opening, an intake port between the first opening and the second opening, and an exhaust port between the first opening and the second opening. In some examples, a front cover assembly can be disposed in the first opening. An inner frame can be coupled to the outer frame, where the inner frame can also define a first aperture and a second aperture. In some examples, a curtain assembly can occlude the second opening. Furthermore, the curtain assembly can include an elastic layer that can define an external surface. The curtain assembly can also include an air-impermeable layer that can define the internal volume.

    Abstract: A fan assembly for a computing device is disclosed. The fan assembly can include an impeller having a number of blades and a motor for turning the blades. The motor can turn the blades via a magnetic interaction between the impeller and the motor. A fluid dynamic thrust bearing can be used to control a position of the impeller relative to the motor. In particular, the impeller can be configured to rotate around an axis and the thrust bearing can be used to control movement of the impeller in a direction aligned with the rotational axis. In one embodiment, the thrust bearing can be configured to stabilize the impeller when vibratory forces act upon the fan assembly. More particularly, parameters associated with the thrust bearing can be selected to counteract vibratory forces emitted by a speaker system.

    Abstract: 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.

    Abstract: An electronic device includes a fan assembly that draws air (including heated air) away from components and forces the air out of the electronic device. The fan assembly includes a guide vane located in the fan housing. Subsequent to air entering the fan assembly via the fan inlets, the guide vane is designed to direct the air to a fan outlet. Further, the guide vane is designed and positioned in the fan assembly to limit or prevent flow separation that may cause the heated air to recirculate and may also cause increased turbulence leading to elevated acoustic noise. Furthermore, the guide vane may include a tapered region to allow the heated air to readily flow over the guide vane to limit or prevent a vortex from occurring within the fan assembly. Using the guide vane, the fan assembly drives more air at the same fan speed and lowers noise generation.

    Abstract: Electronic devices have peripheral drive centrifugal fans having smaller hubs and increased air flows to manage heat levels within the electronic device. A peripheral drive centrifugal fan includes a fan housing, an impeller including a plurality of blades, and a plurality of stacked inductor groups radially disposed about the impeller. Some of the blades have magnetically active portions. Each stacked inductor group includes first and second coils configured to impart a variable magnetic force to the magnetically active portion of a blade to drive the impeller along a rotational direction. The first and second coils can be selectively energizable independently from each other to provide greater control of the impeller.
