Lightweight audio system for automotive applications and method
First Claim
1. A lightweight automotive electronic device comprising:
- at least one electronic circuit component including a circuit board integrally forming a resilient beam portion adjacent an edge thereof carrying a grounding pad; and
a housing assembly substantially formed of a composite of relatively rigid, electrically insulating polymer based material and electrically conductive sheet-like material operable to substantially enclose and to shield said at least one electronic circuit component from electrical anomalies including RFI (radio frequency interference), EMI (electromagnetic interference), BCI (bulk current injection) and/or ESD (electrostatic discharge),wherein said housing assembly includes at least one window formed therein, said window substantially closed by an inwardly exposed segment of said conductive material operative to effect electrical interconnection between said conductive material and said grounding pad.

Abstract
A lightweight radio/CD player for vehicular application includes a case and frontal interface formed of polymer based material molded to provide details to accept audio devices and radio receivers, as well as the circuit boards required for electrical control and display. The case and frontal interface are of composite structure, including an insert molded electrically conductive wire mesh screen that has been pre-formed to contour with the molding operation. The wire mesh provides shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips. The PCB architecture integrally forms a resilient beam portion adjacent an edge thereof carrying a grounding pad.
