A speaker-embeddable seat includes a first speaker that outputs low-frequency sound and is arranged in a seat, and a second speaker that outputs middle-frequency to high-frequency sound and is arranged in a backrest at a position near ears of a seated person. The first speaker is acoustically coupled to a position near ears of a seated person through a duct extending in the backrest, so that low-frequency sound output from the woofer is transmitted to the position. The first speaker, the second speaker, and a front speaker arranged anterior to the speaker-embeddable seat form a sound field. Audio signals that are to be output from the front speaker and the second speaker are subjected to reverberation processing and frequency characteristic conversion so that a sound image is localized anterior to the head of a seated person.
