SPEAKER DEVICE AND METHOD FOR ARRANGING SPEAKERS

摘要

A pair of speakers comprising a left speaker (21) and a right speaker (22) are arranged on an orthogonal plane which is substantially orthogonal to the rotational center axis (Z) about which a listener (10) rotates the head laterally, and on a rotational axis concentric circle (31) which has a center at the rotational center axis (Z) (condition (A)) and at the positions point-symmetric with respect to the rotational center axis (Z) (condition (B)). Even when the head of the listener (10) is laterally rotated about the rotational center axis (Z), any difference in the sound volumes does not occur between the left ear (11) and the right ear (12) since the distance from the left side speaker (21) to the left ear (11) is equal to the distance from the right speaker (22) to the right ear (12).
