Abstract:

Aspects of the invention can include a teleconferencing system having a system housing, a speaker enclosure configured within the system housing, a speaker mounted to the speaker enclosure, and one or more damping cushions coupling the speaker enclosure to the system housing. The one or more damping cushions can suspend the speaker enclosure within the system housing such that the speaker enclosure is separated and mechanically isolated from the system housing by at least a minimum distance (e.g., 2 mm). In some cases, the one or more damping cushions provide the only structural coupling between the speaker enclosure and the system housing. The one or more damping cushions can be configured to dampen mechanical energy generated by the speaker thereby preventing at least a portion of the mechanical energy form coupling to the system housing via the one or more damping cushions.
