摘要： Various implementations include seats and related loudspeakers. In particular cases, a seat includes: a seat headrest portion; a seat backrest portion; and a loudspeaker assembly including: at least one driver for generating an acoustic output; and an acoustic exit fixed in the seat backrest portion and angled to provide the acoustic output to a location below a nominal ear position of an occupant of the seat, wherein an angle of the at least one driver provides the acoustic output to achieve a consistent frequency response across a range of positions deviating from the nominal ear position, wherein the consistent frequency response is characterized by a low frequency (LF) consistency equal to or greater than a LF consistency for an acoustic output provided to the nominal ear position.

摘要： Systems and methods of providing audio through or near a headrest are provided. A headrest includes an adjustable surface positioned to be proximate an occupants head when in use and an acoustic opening is configured to emit acoustic energy from an acoustic transducer in a range of directions in which an ear of the occupant is expected to occupy. The position of the adjustable surface gives some indication of the location of the occupants ear, and various audio signal (driver signal) properties may be adjusted based upon the position of the adjustable surface.

摘要： Various implementations include vehicle headrest configurations and related audio systems. In some particular implementations, a vehicle headrest includes: a main body having a front surface arranged to support a back of a head of a user and a pair of acoustic channels each formed in part by a side wall having a front edge that is offset from the front surface, the main body having a portion configured to receive first and second transducers having a center-to-center spacing of approximately 130 millimeters (mm) to approximately 240 mm, where a dimension (Dimension K) defined by a distance between respective inside surfaces of the side walls of the pair of acoustic channels is related to a dimension (Dimension F) defined by an amount that the front edge of each side wall is recessed from the front surface.

摘要： Various implementations include seats and related loudspeaker assemblies. In particular cases, a seat includes: a seat headrest portion; a seat backrest portion; and a loudspeaker assembly associated with the backrest portion. The loudspeaker assembly can have an acoustic directivity angled upward above a nominal ear position of an occupant.
