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.

說明書

FIG. 8 illustrates a configuration example of an acoustic device 10G according to a seventh embodiment. In FIG. 8, structural elements similar to FIG. 1 are denoted with the same reference signs as FIG. 1, and detailed description thereof will be omitted appropriately. The acoustic device 10G includes the speaker installation member 12 provided with speakers 11LP, 11RP, and 11S. For example, the speaker installation member 12 is fixed to the headrest 13 attached to the upper central portion of the seat back (not illustrated) of the vehicle seat. Note that, the speaker installation member 12 may be fixed to the seat back. Alternatively, the speaker installation member 12 may be integrated with the headrest 13 or the seat back of the seat.

The speaker 11LP is installed on the left front surface of the speaker installation member 12. The speaker 11RP is installed on the right front surface of the speaker installation member 12. The speaker 11S is installed on a central back surface of the speaker installation member 12.

Here, the speaker 11LP and the speaker 11RP 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 M while the headrest 13 is interposed between the speaker 11LP and the speaker 11RP. The speaker 11S is arranged at an intermediate position between the speaker 11LP and the speaker 11RP in the first direction. Note that, the wording “intermediate position” described herein does not have to mean the exact intermediate position. Some minor deviations are allowed.
