A speaker device comprising: a signal processing section (10, 12) configured to perform a signal process with respect to audio signals of a plurality of channels (C, FL, FR, SL, SR); and a speaker array that includes a first speaker units group having a first plurality of speaker units (20-1,...,, 20-7) and a second speaker units group having a second plurality of speaker units (20-8,..... 20-14) for outputting sounds according to the audio signals of the plurality of channels, the first speaker units group being different from the second speaker units group, wherein the signal processing section (10, 12) is configured to perform a first signal process in which sound based on an audio signal of a first channel is set so as to be output from the first speaker units group and a first virtual focus that is a virtual output position of the sound based on the audio signal of the first channel is set to an opposite side of the speaker array, opposite to a sound output direction of the first speaker units group with respect to the speaker array, and sound based on an audio signal of a second channel different from the first channel is set so as to be output from the second speaker units group and a second virtual focus that is a virtual output position of the sound based on the audio signal of the second channel is set to an opposite side of the speaker array, opposite to a sound output direction of the second speaker units group with respect to the speaker array; characterized in that a radiation area of the sound based on the audio signal of the first channel is configured to have a shape that is spread in bilateral symmetry with respect to a line that extends from the first virtual focus to a normal direction of an array plane in which the plurality of speaker units (20-1,..., 20-14) of the first and second speaker units groups (LP, RP) are arranged, and a radiation area of the sound based on the audio signal of the second channel is configured to have a shape that is spread in bilateral symmetry with respect to a line that extends from the second virtual focus to a normal direction of the array plane, by making the first speaker units group and the second speaker units group have the same size, and by making the first virtual focus and the second virtual focus be in a symmetric relationship with respect to the line that extends from the center point between the center portion of the first speaker units group and the center portion of the second speaker units group to the normal direction of the array plane. a signal processing section (10, 12) configured to perform a signal process with respect to audio signals of a plurality of channels (C, FL, FR, SL, SR);
