Abstract
A loudspeaker device includes a loudspeaker box having a space therein, a loudspeaker unit, and a passive radiator. The loudspeaker unit and the passive radiator are attached to the loudspeaker box. The space of the loudspeaker box has a depth smaller on the passive radiator side than on the loudspeaker unit side. This structure allows the loudspeaker device to be mounted on a thin apparatus.
