| description | A loudspeaker device includes: a first loudspeaker that outputs a sound; a second loudspeaker that is adjacent to the first loudspeaker in a predetermined direction and outputs a sound in a direction intersecting with a direction in which the first loudspeaker outputs the sound; and a phase switching circuit that switches between a first switching state and a second switching state, the first switching state being a state in which an input sound signal is inputted to both the first loudspeaker and the second loudspeaker, the second switching state being a state in which the input sound signal is inputted to one of the first loudspeaker and the second loudspeaker while an inverted sound signal obtained by inverting a phase of the input sound signal is inputted to the other of the first loudspeaker and the second loudspeaker. |
