Abstract
The technology described in this document can be embodied in a system that includes a seat headrest enclosing at least one first acoustic transducer that generates audio output in a first frequency range. The system also includes an adjustable headrest wing disposed in front of the seat headrest, the headrest wing being pivotally coupled to the seat headrest and adjustable to one of multiple positions. The headrest wing includes at least one second acoustic transducer that generates audio output in a second frequency range that includes frequencies higher than the upper end of the first frequency range. The system further includes a controller configured to adjust, for a given position of the headrest wing, one or more parameters of at least one of: (i) the first acoustic transducer and (ii) the second acoustic transducer in accordance with a target acoustic distribution.
