FIELD: transport machine building.
SUBSTANCE: group of inventions relates to integrated audio system built into bowl of vehicle seat headrest bowl. Seat assembly has a lower part of the seat and a seat back extending upwards from the lower part of the seat. Seat back comprises forward facing surface, rearward surface and head restraint mounted on upper seat back fragment and received in headrest bowl. Headrest bowl is located on forward facing backrest surface. Speaker assembly is mounted in the headrest bowl. Resonance cavity is formed close to the headrest cup, into which the speaker assembly is received. Resonant cavity comprises an upper opening into the headrest bowl located in the lower fragment of the headrest bowl. Upper opening receives a speaker assembly and a passive radiator located on the rear side of the resonance cavity.
EFFECT: enabling creation of a sound system which improves personalization of audio content perception.
