Abstract
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.
