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. 7 illustrates a configuration example of an acoustic device 10F according to a sixth embodiment. In FIG. 7, structural elements similar to FIG. 6 are denoted with the same reference signs as FIG. 6, and detailed description thereof will be omitted appropriately. The acoustic device 10F includes the speaker installation member 12 provided with the speakers 11LP, 11RP, 11SA, and 11SB in a way similar to the acoustic device 10E illustrated in FIG. 6.

The speaker 11LP is driven by the left ear signal SL including the low frequency component and the middle and high frequency component for stereophonic reproduction (virtual surround). The speaker 11RP is driven by the right ear signal SR including the low frequency component and the middle and high frequency component for the stereophonic reproduction (virtual surround).

The signal processor 14LH processes the middle and high frequency component SLH obtained by the high-pass filter 15LH and generate the reversed-phase signal SLH′ with an adjusted level in such a manner that the speakers 11LP and 11SA reproduce the middle and high frequencies of the left ear signal with unidirectional directivity as indicated by a dash-dotted line. Note that, to simplify the drawing, the unidirectional directivity of the middle and high frequencies of the right ear signal reproduced by the speakers 11RP and 11SB (to be described later) are not illustrated.
