Abstract:
1. A speaker assembly which is adapted to be mounted to a wall structure and arranged to operate in a manner to diminish unwanted noise that can result from vibratory motion of the wall structure to which it is mounted, said speaker assembly comprising: a speaker section comprising at least one speaker that in turn comprises a diaphragm, section that moves with a back and forth motion to create back and forth speaker inertial forces; and an inertial noise suppression section comprising an inertial mass which is movable in an arcuate manner to generate off-setting inertial forces to diminish and/or substantially off-set said speaker inertial forces that would otherwise create a noise producing vibratory motion of the wall structure to which the speaker assembly is mounted, wherein the speaker assembly has an input drive connection by which an amplified electric signal may be transmitted to the speaker of the speaker section, and the amplified electric signal is at the same time directed to a drive section of the inertial noise suppression section, so that the inertial mass is moved synchronously with the movement of the diaphragm section.
