Loudspeaker device

A speaker device (100) is provided with: a speaker (1) that outputs sound; a speaker (2) that is disposed adjacent to the speaker (1) in a predetermined direction and outputs sound in a direction intersecting the direction in which the speaker (1) outputs sound; and a phase switching circuit (6) capable of switching between a first switching state in which the same input sound signal is inputted to each of the speaker (1) and the speaker (2), and a second switching state in which the input sound signal is inputted to one of the speaker (1) and the speaker (2), and a second switching state in which the input sound signal is inputted to the other of the speaker (1) and the speaker (2). A state of an inverted sound signal, which is a sound signal obtained by inverting the phase of the input sound signal, is input to the other of the speaker (1) and the speaker (2). 扬声器装置(100)具备：扬声器(1)，输出声音；扬声器(2)，以与扬声器(1)在规定的方向上相邻的方式而被配置，向与扬声器(1)输出声音的方向交叉的方向输出声音；以及相位切换电路(6)，能够对第1切换状态和第2切换状态进行切换，所述第1切换状态是扬声器(1)以及扬声器(2)分别被输入相同的输入声
