A speaker device comprises a first speaker unit and a second speaker unit which, for example, reproduce at least high-frequency sound, and has a configuration in which the first speaker unit and the second speaker unit are disposed on planes with a horizontal direction and a vertical direction as the axes thereof, respectively, the first speaker unit is disposed to face in a horizontally forward direction, the second speaker unit is disposed to face in a vertically upward direction at approximately 90 degrees to the first speaker unit, and the second speaker unit is disposed such that, when the center of a diaphragm securing surface of the first speaker unit is disposed at the origin of the plane, a horizontally backward direction is set as X, and the vertically upward direction is set as Y, the coordinates of the center of a diaphragm securing surface of the second speaker unit are disposed on a straight line represented by the following expression on the plane. (expression) Y=-aX+b (where a>0, b>0, X>0, Y>0) |
