Abstract: A hearing device such as a hearing aid, ear pod, headphone, or other wearable is provided, whose components include the following: an acoustic transducer with a vent port operable to produce sound, a housing of the acoustic transducer with a sound opening, and an actuatable acoustic valve disposed in the housing, where the acoustic valve is actuatable to alter passage of sound through the acoustic vent to change the state of the hearing device between an open vent state and a closed vent state, so that actuation of the valve changes an acoustic characteristic of the hearing device.

Abstract: Acoustic valves include a housing having an acoustic inlet, an acoustic outlet, and an acoustic passage between the inlet and the outlet. An electrical coil is disposed in the housing and configured to generate a magnetic field when energized by an actuation signal. A spring is coupled to an armature movably disposed in the housing between a first surface and a second surface. The valve has a first stable state wherein the armature is positioned against one surface when the electrical coil is not energized, and the valve has a second stable state wherein the armature is positioned against the other surface when the electrical coil is not energized. The armature is movable between the first and second states when the electrical coil is energized, wherein the acoustic passage is more obstructed when the armature is in one state than when the armature is in the other state.

Abstract: The present disclosure pertains to hearing devices configurable between open fit and closed fit configurations at different times through actuation of one or more acoustic valves located in one or more corresponding sound passages of the hearing device. The one or more acoustic valves of the hearing device are adaptively controlled based on context detected by one or more sensors. The context may be, but is not limited to, a mode of operation of the hearing devices which may include, for example, an audio content playback mode and a voice communication mode. The actuatable valves may be actuatable in situ without having to remove the hearing device from the user's ear thereby enabling the user to experience the benefit of a closed fit or an open fit depending on the user's desire or other context.

Abstract: A microphone assembly includes a housing including a sound port and an external-device interface having a plurality of electrical contacts. An acoustic transducer, such as a MEMS microphone, is disposed in the housing and is in acoustic communication with the sound port. An electrical circuit is disposed in the housing that is electrically coupled to the acoustic transducer and to electrical contacts on the external-device interface. A magnetic transducer including an electrical coil disposed about a core, such as a telecoil or charging coil configuration, is fastened to the housing. The electrical coil having leads, at least one of the leads electrically terminated at a coil contact of the housing.
