The invention relates to an audio system for a seat headrest, the seat headrest, and a related vehicle, a method, and a program. The audio system for a seat headrest having a set of R right speaker(s), a set of L left speaker(s), and an electronic chain (10) configured to emit a sound signal from at least a right input signal (RIN) and a left input signal (LIN). The electronic chain includes a separating module (16) configured to obtain, from the right input signal (RIN) and the left input signal (LIN), at least four mono audio components (CL, AL, CR, AR), and a sound spatialization module (18) configured to apply, to each mono audio component delivered by the separating module (16), a binaural filter (B1, B2, ..., BN) 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.
本发明涉及座椅头枕的音频系统、座椅头枕及相关车辆、方法和程序。该音频系统包括:R个右扬声器的组;L个左扬声器的组;以及电子链(10),该电子链被配置为至少从右输入信号(RIN)和左输入信号(LIN)发出声音信号,电子链包括:分离模块(16),该分离模块被配置为从右输入信号(RIN)和左输入信号(LIN)获得至少四个单声道音频分量(CL、AL、CR、AR);声音空间化模块(18),该声音空间化模块被配置为对由分离模块(16)递送的各个单声道音频分量(CL、AL、CR、AR)应用先前从所述多个双耳滤波器(B1、B2...BN)选择的并且专用于所述音频分量的双耳滤波器,这产生源位置与所述先前选择的双耳滤波器关联的声音。
