Automotive loudspeaker having variable speaker orientation and particular electrical connections

A composite speaker system for automotive vehicles in which a low-range speaker unit is mounted flush with a rear parcel shelf of the vehicle and a medium- and high-range speaker is mounted above the low-range speaker having an angular orientation which is adjustable in a vertical plane with respect to the center axis of the low-range speaker wherein the medium- and high-range speaker can be directed into the passenger compartment without reflection from the rear window. In one embodiment, the medium- and high-range speaker is rotatably mounted upon a grill frame which is detachably disposed upon and engaged with the open surface of the low-range speaker. In a second embodiment, first and second spacers extend from the center of the low-range speaker through the grill frame for the low-range speaker. In this case, the medium- and high-range speaker is tiltably mounted upon the upper end of the spacers. The medium- and high-range speaker may also be made horizontally rotatable.

Car speaker system

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.
