Abstract
A loudspeaker device includes a loudspeaker unit and an enclosure. The loudspeaker unit outputs sounds mainly in a first direction, upon receiving an electric signal. The enclosure is configured with at least a part of an interior member of a movable-body device, and secures and accommodates the loudspeaker unit in the inside of the enclosure. The interior member includes a body part, and an accommodation part that accommodates the loudspeaker unit therein and is formed integrally with the body part. The accommodation part is larger in dimension along the first direction than the body part.
