Abstract
A projector includes a first housing, a second housing, and a sound insulating member. The first housing is provided with first heat-generating elements used for generating an image, first fans producing cooling airflows towards each one of the first heat-generating elements, and vents via which the cooling airflows heated by the first heat-generating elements are discharged. The second housing encloses the first housing, and has second fans discharging the cooling airflows outside the projector. The sound insulating member is provided on a path between the vents and the second fans so as to insulate sound produced by the first fans. The projector may be provided with a dust-proof member for the projecting lens.
