Abstract: An anti-vibration device for attaching a compact disk player to an automobile is disclosed whereby the player is positively retained in place and is not subjected to the shocks and vibrations of the vehicle during its normal operation. The device has a generally planar base, a support plate defining a supporting surface for the compact disk player, a clamp to clamp the compact disk player to the support plate and an anti-vibration layer to attach the support plate to the base. The anti-vibration layer has a layer of foam material, which may be a polyurethane foam, and one or more compression coil springs. The use of the foam material serves to dissipate the resonances of the compression spring and provides an effective connection between the support plate and the base. The foam and the coil springs are arranged in such a way that the support plate may move freely with respect to the base.
