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 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 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.
