Abstract:
A lightweight audio player for vehicular application is virtually “fastenerless” and includes a fold-up case formed of polymer based material molded to provide details to accept audio devices, as well as the circuit boards required for electrical control and display. The case is of composite structure, including an insert molded electrically conductive wire mesh screen. The wire mesh provides shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips. Side wall closure members define self-engaging attachment features for affixing to the case, providing electrical self-grounding with the wire screen and thermal grounding with internal power devices. The major components and subassemblies are self-fixturing during the final assembly process, eliminating the need for dedicated tools, fixtures and assembly equipment.
