摘要

To favorably reduce crosstalk components output from respective speakers that reproduce left and right ear signals.Directivity is given to a left ear signal and a right ear signal and the left ear signal and the right ear signal are reproduced by using at least two respective speakers arranged back-to-back to reduce crosstalk components. For example, the speaker may be a speaker installed in a headrest or a seat provided with the headrest. For example, the directivity given to the left ear signal and the directivity given to the right ear signal may be bidirectional directivity or unidirectional directivity.

Among two adjacent seats, an A-side seat (left-side seat) includes a speaker installation member 12A provided with speakers 11LA and 11RA. Here, the speaker 11LA and the speaker 11RA are arranged at a predetermined interval in a first direction (indicated by an arrow P) corresponding to a left and right direction of a listener MA while a headrest 13A is interposed between the speaker 11LA and the speaker 11RA. The speaker installation member 12A is fixed to the headrest 13A attached to the upper central portion of the seat back (not illustrated) of the seat. Note that, the speaker installation member 12A may be fixed to the seat back. Alternatively, the speaker installation member 12A may be integrated with the headrest 13A or the seat back of the seat. The speaker 11LA is a speaker for reproducing the left ear signal, and the speaker 11RA is a speaker for reproducing the right ear signal.
