    Abstract: An acoustic device such as a microphone or speaker is positioned with and coupled to a housing to connect an acoustic port of the acoustic device with an external opening of the housing. A reservoir is connected to the external opening via a bleed channel. The bleed channel may be less resistive to liquid ingress than the acoustic port. As such, the reservoir and bleed channel may redirect liquid from the external opening away from the acoustic port. In some implementations, the reservoir and/or the bleed channel may be defined by one or more acoustically permeable barriers such as meshes that cover the acoustic port, compressible materials such as foams that form a perimeter around the acoustic port, and/or adhesive layers that couple the acoustic device, the housing, and/or one or more other components.

    Abstract: A method of improving voice quality in a mobile device starts by receiving acoustic signals from microphones included in earbuds and the microphone array included on a headset wire. The headset may include the pair of earbuds and the headset wire. An output from an accelerometer that is included in the pair of earbuds is then received. The accelerometer may detect vibration of the user's vocal chords filtered by the vocal tract based on vibrations in bones and tissue of the user's head. A spectral mixer included in the mobile device may then perform spectral mixing of the scaled output from the accelerometer with the acoustic signals from the microphone array to generate a mixed signal. Performing spectral mixing includes scaling the output from the inertial sensor by a scaling factor based on a power ratio between the acoustic signals from the microphone array and the output from the inertial sensor. Other embodiments are also described.

    Abstract: Intra-concha earphones are disclosed. In an embodiment, an intra-concha earphone includes a housing having a rear space divided into a back volume, a bass duct, and a vent chamber between a driver and a rear wall. The vent chamber may be acoustically coupled with the back volume through both an acoustic port and the bass duct. Furthermore, the vent chamber may be acoustically coupled with a surrounding environment through a vent port, which may be a sole acoustic opening in the rear wall. Thus, sound emitted by the driver may propagate through the acoustic port and the bass duct to meet in the vent chamber before being discharged through the vent port to the surrounding environment. Other embodiments are also described and claimed.

    Abstract: A headphone can include plurality of exterior microphones, that generates corresponding exterior microphone signals, an accelerometer that generates an accelerometer signal; and an interior microphone, not directly exposed to the environment, that generates an interior microphone signal. A processor of the headphone can be configured to generate an audio signal containing voice of a user, based on a) the accelerometer signal, b) the interior microphone signal, and c) the plurality of exterior microphone signals.
