Loudspeaker device and movable-body device equipped with the same

A loudspeaker device used in a movable-body device including a space for housing a spare tire and a lid for closing the space, the loudspeaker device comprising:

• a plurality of loudspeaker units each including a diaphragm for outputting a sound mainly in a first direction upon receiving an electric signal;
• and
• an enclosure configured with at least a part of the lid of the movable-body device, the enclosure securing and accommodating the plurality of loudspeaker units in an inside of the enclosure, wherein
• the enclosure includes:
• a body part;
• a plurality of accommodation parts accommodating the plurality of loudspeaker units, respectively, being formed integrally with the body part, and being larger in dimension along the first direction than the body part, the plurality of accommodation parts being equal in number to the plurality of loudspeaker units;
• and
• a plurality of duct parts extending from the plurality of accommodation parts toward the lid, respectively, wherein
• each of the plurality of accommodation parts includes:
• a plate facing the diaphragm in the first direction so as to face the diaphragm;
• and
• an acoustic space enclosed by one of the plurality of loudspeaker units and the plate, wherein
• the plate is configured to propagate sound outputted from the diaphragm in the first direction toward a corresponding one of the plurality of duct parts in a direction different from the first direction, and
• each of the plurality of duct parts connects the acoustic space and an inside of the movable-body device,
• each of the plurality of the accommodation parts includes a side face on an inner side of the the lid,
• the side face has a circular arc shape as viewed from an opposite direction to the first direction, and
• the side face of each of the plurality of the accommodation parts forms a part of an identical circle as viewed from the opposite direction.
