Abstract
An electronic device (100) comprises a housing (222), a circuit supporting substrate (454, 456) within the housing and mechanically coupled thereto, and electronic circuitry (744, 746, 748, 750, 752) mechanically coupled to the circuit supporting substrate (454, 456). The electronic device (100) further comprises a mechanical shock isolation member (760, 762, 1312) within the housing (222) and mechanically coupled to the circuit supporting substrate (454, 456) for substantially increasing the natural mechanical frequency of vibration of the circuit supporting substrate (454, 456). The mechanical shock isolation member (760, 762, 1312) comprises an element (1313) having a planar surface (1315). The mechanical shock isolation member (760, 762, 1312) further comprises protuberances (1314) mechanically coupled to and extending perpendicularly from the planar surface (1315) for absorbing a tolerance build-up.
