Abstract: Embodiments describe an eartip including an eartip body having an attachment end and an interfacing end opposite from the attachment end. The eartip body can include an inner eartip body having a sidewall extending between the interfacing end and the attachment end, the sidewall defining a channel and having a first thickness near the attachment end and a second thickness different from the first thickness at the interfacing end. The eartip can also include an attachment structure coupled to the inner eartip body at the attachment end, the attachment structure having an inner surface and an outer surface. The attachment structure can include an upper region interfacing with the sidewall and defining discrete through-holes, a lower region below the upper region where the inner surface defines a plurality of recesses positioned around the lower region, and a mesh extending across the channel and into the upper region.

Abstract: A system such as a vehicle, building, vessel, aircraft, or electronic device system may have a layer of material with invisible laser-drilled openings. The layer of material may include an outer layer of fabric overlapping an inner layer such as an inner foam layer. Laser-drilled openings may include outer openings in the fabric layer and inner openings in the foam layer. Each of the inner openings may be overlapped by multiple outer openings. The exposed surface of the fabric layer may have strands of material of different appearances and/or may otherwise be configured to help visually hide the laser-drilled openings. Laser-drilled openings may also have small sizes to help make the laser-drilled openings invisible. Laser-drilled openings may overlap components such as audio components, heating and cooling components, and/or light-emitting components.

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 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.
