Abstract

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.

Description

【Technical field】 [0001] The invention relates to an audio system for a seat headrest, the audio system comprising: a group of R right loudspeakers; a group of L left loudspeakers; and a control unit comprising an electronic chain configured to To emit a sound signal from at least one pair of input signals comprising a right input signal and a left input signal, so as to reproduce sound via a pair of channels comprising a right channel and a left channel, the respective ends of which are sets of R right loudspeakers and a group of L left speakers, R and L are integers greater than or equal to one, and each speaker is configured to be integrated into the headrest. [0002] The invention also relates to a seat headrest designed to be coupled to the backrest of a seat, which headrest is equipped with such an audio system. [0003] The invention also relates to a passenger vehicle, in particular a motor vehicle, comprising one or several seats, at least one of which is equipped w...
