Abstract

In a speaker set having an enclosure containing a drive unit, a flying bridge is arranged to interconnect inner walls of the enclosure. The flying bridge is formed with a recess at location excluding a portion abutting the inner walls, and a damping material is fitted in the recess for absorbing vibration of the enclosure. Typically, the flying bridge interconnects opposite ones of the inner walls of the enclosure. The flying bridge is composed of a plurality of wedge-shaped parts contacting each other at planes oblique to the inner walls interconnected by the flying bridge, and the wedge-shaped parts are arranged such that a front end of one wedge-shaped part is directed opposite to a front end of another wedge-shaped part which is adjacent to the one wedge-shaped part.
