Abstract: Implementations of the subject technology provide occupant-based audio for enclosed environments. For example, an apparatus having an enclosure and one or more speakers may determine a location and/or an identity of an occupant within an enclosed environment defined by the enclosure, and operate the one or more speakers to provide audio output to the location of the occupant. The apparatus may also operate the one or more speakers to reduce the audio output to one or more other locations within the enclosure, such as to one or more non-occupant locations and/or to one or more locations of one or more other occupants. The audio output may be occupant-specific audio output, such as a personalized notifications, in one or more implementations.

Abstract: Implementations of the subject technology provide a access-feature-mounted external speaker. The access-feature-mounted external speaker may be disposed within an internal cavity in the door, and acoustically coupled to a slot in an edge of the door by an acoustic duct. In a closed position of the door, sound from the access-feature-mounted external speaker may be projected into a gap between the door and a structural interface of an enclosure, and redirected in part by the structural interface to a location external to the enclosure. In an open position of the door, sound from the speaker may be projected into an opening in the enclosure.

Abstract: Implementations of the subject technology provide for sound stage reversal for enclosed environments. For example, various occupants within an enclosed environment and listening to the same spatially-oriented audio content may be facing in various different respective directions. Speakers within the enclosed environment may be operated to generate the spatially-oriented audio content for the various occupants, with various respective sound stage orientations corresponding to the various different respective directions in which the occupants face.

Abstract: Implementations of the subject technology provide for audio integration of portable electronic devices into enclosed environments. A portable electronic device may be carried, by a user, into an enclosed environment, such as into an enclosure of a building, a room, or other apparatus. One or more remote speakers may be disposed in the enclosed environment. The remote speaker(s) may be operated in cooperation with the portable electronic device to spatially coordinate audio output from the remote speaker(s) with video content displayed by the portable electronic device.

Abstract: Implementations of the subject technology provide directional acoustic devices such as directional speakers. A directional speaker may include a sound-generating component that projects sound from an acoustic port, and has a rear or interior surface that interfaces with a back volume of the speaker. The directional speaker may also include one or more acoustic ducts coupled to the back volume that direct a negative polarity version of the sound to one or more desired locations in an external environment of the speaker. The negative polarity version of the sound may cancel portions of the sound projected from the acoustic port, at one or more desired locations in the external environment that are determined by the arrangement of the acoustic duct(s).

Abstract: Implementations of the subject technology provide directional audio for enclosed environments. In one or more implementations, an apparatus may include an enclosed environment, and one or more a dual directional speakers, one or more ringed arrays of speakers, one or more isobaric cross-firing speakers, and/or one or more door-mounted speaker arrays that are operable to direct sound to one or more desired locations within the enclosed environment.
