An audio system for a headrest having a set of R right speaker(s), a set of L left speaker(s), and an electronic chain configured to emit a sound signal from at least a right input signal and a left input signal. The electronic chain includes a separating module configured to obtain, from the right input signal and the left input signal (L.sub.IN), at least four mono audio components, and a sound spatialization module configured to apply, to each mono audio component delivered by the separating module, a binaural filter previously selected from the plurality of binaural filters, and dedicated to the audio component, producing a sound whose source position is associated with the previously selected binaural filter.

Active noise control systems and methods are disclosed that include generating with a first sub-system, anti-noise that is configured to reduce or cancel noise occurring at a listening position. Generating with a second sub-system, anti-noise that is configured to reduce or cancel noise occurring at the listening position. The first active noise control sub-system has a higher robustness than the second active noise control sub-system.

Active noise control system and methods are disclosed that include generating anti-noise that is configured to reduce or cancel noise occurring at a listening position in the ambiance of a seat with a backrest enclosing a hollow volume. Radiating the anti-noise from within the hollow volume of the backrest of the seat.

A headrest assembly is removeably supported on a vehicle seat having a seatback with a seatback frame. The headrest assembly includes a headrest bun operably coupled to a housing via a powered linkage system for driving the headrest bun between extended and retracted positions. A temperature control system is disposed in the housing and configured to provide treated air to a conditioning area disposed below the headrest bun at a vehicle occupant's neck. The temperature control system includes a blower operably coupled to duct assembly for blowing air treated by a thermoelectric module along the duct assembly. One or more vents are disposed at a downward angle on a front portion of the housing. The one or more vents are operably coupled to and in communication with the duct assembly.

A vehicle is provided to minimize the difference in left and right output intensity of a headrest speaker by adjusting an output intensity of based on the position of the passenger's ear. The headrest includes a left-side speaker provided on the left-side of the headrest of a seat inside the vehicle to output sound and a right-side speaker provided on the right-side of the headrest to output sound. A pressure sensor measures a force applied to the headrest and a controller adjusts the output intensity of the left speaker and the right speaker based on an action point of the force measured by the pressure sensor.

A device configured for a vehicle for supporting and massaging a neck of a passenger is provided. The device is configured such that a neck support pad is integrally formed on a lower end portion of a headrest to hold up and support the neck of a passenger, and a massage device is mounted in the neck support pad to massage the neck of the passenger, thus stably supporting and massaging the neck of the passenger sitting on a seat.

Various implementations include vehicle headrest configurations and related audio systems. In some cases, a headrest includes: a main body having a front surface to support a back of a user's head 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, where a transducer mount in each of the pair of acoustic channels for mounting respective ones of the first and second transducers, wherein a dimension (Dimension C) is defined by a rotation angle of the transducer mount relative to a centerline of the vehicle headrest, wherein Dimension C is approximately −20 degrees to approximately zero degrees.
