The dimensions of the three principal components are selected such that a speaker enclosure is supported just above a carpet with the pin extending down through the carpet, through any backing or pad beneath the carpet and to an underlying rigid floor, typically concrete. This serves to directly couple the speaker enclosure to the massive substructure. The diameter of the pin is preferably no more than about one-eighths inch in order to prevent significant damage to the carpet and underlying pad. Preferably, the resilient damper element is fabricated from a urethane-based polymer material which achieves controlled additional damping in the critical bass frequencies.Type: GrantFiled: December 7, 1995Date of Patent: October 28, 1997Inventor: Alexei Sheydayi

Patent number: 5566919Abstract: A motor mount for reducing vibration and noise associated with motor load imbalances. The mount includes a one-piece elastomeric support having a motor attachment portion from which a plurality of supporting legs extend. Prior to assembly, the amount has a planar configuration. In assembly, the motor attachment portion is positioned around and secured to the motor by a clamp. Brackets are provided to secure the legs to a base. The mount provides the motor with pivotal freedom of motion but prevents substantial vertical displacement of the motor. The motor mount is well suited for use in centrifuges and other apparatus in which load imbalances cause vibration. In one embodiment, the mount includes three legs so that, in assembly, the mount is tripod-like.Type: GrantFiled: October 13, 1994Date of Patent: October 22, 1996Assignee: Norfolk Scientific, Inc.Inventor: Larry E.
