  • Publication number: 20020162937
    Abstract: Proposed is a piece of audio electrical or audio electronic equipment or component thereof, having at least one combined spring-damper element (14) for supporting the equipment (13) or its component on a surface (15) in such a way that the resonance frequency of the spring-damper element (14) is below 20 Hz. The defined natural frequency of the support outside of self-starting vibrations along with the damping results in a significantly improved sound quality while protecting against external influences, such as structure-borne noise and airborne noise, as well as against self-starting vibrations of the piece of equipment, by damping them.
