Abstract: A head-mounted display system is disclosed that includes a housing; a visual system associated with the housing to facilitate image and/or video display; a wearable support connectable to the housing; and an audio component pivotably connected to the support such that the audio component is movable between a first position in which the audio component is in general alignment with the support, and a second position in which the audio component is out of general alignment with the support. Movement from the first position to the second position transitions the audio component from a first mode (i.e., an extra-aural mode) in which sound is projected through a first port in communication with a driver to a user to a second mode (i.e., an intra-aural mode) in which sound is projected through a second port in communication with the driver to the user.

Abstract: An electronic device comprising having an enclosure with an enclosure wall separating a surrounding environment from an encased space. The enclosure wall includes a top portion having an acoustic channel extending from the encased space to the surrounding environment and a bottom portion. A microphone assembly module positioned within the encased space, and having a microphone acoustically coupled to a sound inlet port that is aligned with the acoustic channel and an air permeable water resistant membrane. A first support member is dimensioned to translatably couple the microphone assembly module to the top portion of the enclosure wall and translate the microphone assembly in response to a pressure change within the acoustic channel, and a second support member is dimensioned to translatably couple the microphone assembly module to the bottom portion of the enclosure wall.

Abstract: An acoustic module is coupled to an acoustic passage. The acoustic module includes an acoustic transducer coupled to a diaphragm. A controller or other circuitry measures an impedance of the acoustic transducer. Based on the impedance, the controller determines whether the impedance indicates that the acoustic passage is blocked. The controller may determine that the acoustic passage is blocked by liquid that is present in the acoustic passage. When the controller determines based on the impedance that liquid is present in the acoustic passage, the controller may drive out, purge, and/or otherwise remove the liquid, such as by using the acoustic transducer to vibrate the diaphragm.

Abstract: An electronic device having a microphone behind a water resistant, air-impermeable membrane is disclosed. Embodiments include a trapped volume of air between the membrane and the microphone. A barometric equalization element may define an acoustic leak path, e.g., a tortuous leak path, between the trapped volume of air and an encased space within a casing of the electronic device. Other embodiments are also described and claimed.
