Patent abstract
An on-wall loudspeaker and mounting apparatus includes an enclosure, a loudspeaker driver mounted in the enclosure, brackets of equal length and attachable to a wall, arms of equal length pivotably attached to the brackets and pivotably attached to the enclosure, each arm pivotable perpendicular to the wall. A movement of a cone in the driver is parallel to the pivoting of the arms when an alternating current signal is applied to the driver. The present invention mitigates vibrations transmitted to walls and other building structures, and provides improved means for reproducing low frequencies below a range of conventional loudspeakers.
