A portable multimedia projection system (100, 200, 300, 400) includes a portable housing (120, 220, 320, 420), a media player (27), a sound system (32/34/36), an image projection device (22), a controller (90) and a vibration dampening device (50, 60). The sound system (32/34/36) has at least one internally-mounted speaker (32, 34, 36). The image projection device (22) externally projects images. The controller (90) is electrically coupled to the media player (27), the sound system (32/34/36) and the image projection device (22). The controller (90) directs audio signals from the media player (27) to the sound system (32/34/36) and directs video signals from the media player (27) to the image projection device (22). The vibration dampening device (50, 60) is coupled between the housing (120, 220, 320, 420) and at least one of the media player (27), the at least one internally-mounted speaker (32, 34, 36) and the image projection device (22).
