Claims
- 1. Consumer electronics apparatus with vibration-sensitive components for installation and operation in vehicles, comprising: housing means; a vehicle element and main resilient elements having attenuating properties between said housing means and said vehicle element for preventing shock and vibrations from being transmitted from said housing means to said vehicle element, said vehicle element having a resonance frequency, said vibration-sensitive components having an effective resulting isolation resilience; means for adjusting said resonance frequency by varying said effective resulting isolation resilience and thereby optimizing operating reliability of said components; said apparatus being a compact disk player installed in a vehicle; said adjusting means having supplemental resilient elements distributed symmetrically to said main resilient elements; said housing means holding said vibration-sensitive components and having two bores; said vehicle element having two pins at substantially the same location as said bores, said supplemental resilient elements extending through said bores and being rotatable to secure releasably said supplemental resilient elements to said housing means, said supplemental resilient elements extending between said pins and said bores, said supplemental resilient elements exerting a pressure component on said vehicle element for relieving said main resilient elements, said vehicle element having a weight resting on said main and supplemental resilient elements.
- 2. Consumer electronics apparatus as defined in claim 1, wherein said housing means holds said vibration-sensitive components, said housing means being closable.
- 3. Consumer electronics apparatus as defined in claim 1, wherein said adjusting means varies said resilience by varying the number of supplemental resilient elements.
- 4. Consumer electronics apparatus with vibration-sensitive components for installation and operation in vehicles, comprising: housing means; a vehicle element and main resilient elements having attenuating properties between said housing means and said vehicle element for preventing shock and vibrations from being transmitted from said housing means to said vehicle element, said vehicle element having a resonance frequency, said vibration-sensitive components having an effective resulting isolation resilience; and means for adjusting said resonance frequency by varying said effective resulting isolation resilience and thereby optimizing operating reliability of said components; said apparatus being a compact disk player installed in a vehicle; said adjusting means housing supplemental resilient elements distributed symmetrically to said main resilient elements; said housing means holding said vibration-sensitive components and having two bores; said vehicle element including a chassis having two pins at substantially the same location as said bores, said supplemental resilient elements extending through said bores and being rotatable to secure releasably said supplemental resilient elements to said housing means, said supplemental resilient elements extending between said pins and said bores, said supplemental resilient elements exerting a pressure component on said vehicle element for relieving said main resilient elements, said vehicle element having a weight resting on said resilient elements; said resilience being variable by varying the number of main and supplemental resilient elements.
- 5. Consumer electronics apparatus with vibration-sensitive components for installation and operation in vehicles, comprising: housing means; a vehicle element and resilient elements having attenuating properties between said housing means and said vehicle element for preventing shock and vibrations from being transmitted from said housing means to said vehicle element, said vehicle element having a resonance frequency, said vibration-sensitive components having an effective resulting isolation resilience; and means for adjusting said resonance frequency by varying said effective resulting isolation resilience and thereby optimizing operating reliability of said components; said means for adjusting said resonance frequency comprising a system of magnets affecting said resilience; a magnetic component on said vehicle element; said system of magnets comprising a system of electromagnets; an induction coil on said housing means and in alignment with said magnetic component on said vehicle element, said induction coil having excitation current, said resonance frequency being adjustable by varying said excitation current; means for detecting amplitude of acceleration of said vehicle element relative to said housing means; capacitor means for superimposing on alternating signal on said excitation current; said housing means holding said vibration-sensitive components, said alternating voltage being a measure of said amplitude of acceleration of said vehicle element relative to said housing means.
