Abstract
A car speaker system which can be used to radiate sound either inside the vehicle in normal driving use or outside the vehicle when the vehicle is parked. A plurality of speaker units are mounted in a closed cabinet and the cabinet is swingably mounted along one side thereof in a casing. In a first swinging position of the cabinet, the speaker mounting surface of the cabinet is flush with the ceiling panel and the speakers radiate sound downwards into the passenger compartment of the vehicle, while in a second swinging position of the cabinet, the speaker mounting surface is perpendicular to the ceiling panel and the speakers face rearwards to radiate sound to the exterior through an open hatchback door.
