Abstract (en)
[origin: WO2016066960A1] The invention relates to a seat back (10) comprising an improved sound-emitting device for the seat occupant, formed by a rigid chamber (11) covered by a lining (10a) and supporting two loudspeakers (16) for transmitting sound on each side of the guides (12) for the headrest poles, characterised in that the rigid chamber (11) comprises a resonator (20) disposed between the loudspeakers (16), allowing distortion at low frequencies to be reduced and a quality HiFi sound to be produced.
