Abstract: A consumer electronics apparatus, such as a compact disk player installed and operated in a vehicle, includes resilient elements whose attenuation properties prevent shock and vibrations from being transmitted from a base or housing to a chassis or drive mechanism. The resonance frequency is made adjustable while the housing is closed, by adding or removing supplemental resilient elements. Alternatively, the resilience of individual resilient elements may be adjusted by way of a screw. These adjustments vary an effective resulting isolation resilience and thereby optimize reliability of the components. In another embodiment, a system of permanent magnets or electromagnets may be used together with the main resilient elements.
