Acoustic output through headrest wings

A headrest of a seat, comprising:

• a housing for providing structural support to the seat headrest, the housing including a recessed portion;
• and
• an adjustable headrest wing disposed at least in part within the recessed portion, the headrest wing comprising:
• one or more acoustic transducers,
• a surface for supporting at least a portion of the head of an occupant,
• a perforated external layer covering at least a portion of the surface, the perforated external layer configured to pass acoustic signals generated by the one or more acoustic transducers,
• at least one acoustic channel disposed between the one or more acoustic transducers and the perforated external layer, and
• a pivot for coupling the headrest wing to the housing such that the headrest wing is adjustable to one of multiple positions within an angle range around the pivot, wherein at each of the multiple positions of the headrest wing, at least a portion of the one or more acoustic transducers is disposed within the recessed portion of the housing, the one or more acoustic transducers configured to pass the acoustic signals to the at least one acoustic channel at each of the multiple positions.

A headrest of a seat, comprising:

• an enclosure for housing one or more acoustic transducers;
• an adjustable headrest wing disposed in contact with the enclosure, and configured to be adjusted to one of multiple positions within an angle range around a hinge;
• and
• an acoustic channel disposed between the one or more acoustic transducers and a front surface of the headrest wing, the acoustic channel configured to vary in length in accordance with adjustments to the adjustable headrest wing, the acoustic channel permitting audio signals from the one or more acoustic transducers to be radiated outward through the front surface of the headrest wing.
