Abstract:
1. An on-wall loudspeaker and mounting apparatus comprising: an enclosure; a loudspeaker driver mounted in the enclosure; a plurality of brackets each having a substantially equal length and each having a proximal end attachable to a wall; a plurality of arms each having a top end pivotably attached to a respective distal end of each of the brackets and a bottom end pivotably attached to the enclosure, each arm pivotable in a plane of rotation substantially perpendicular to the wall, and each arm having a substantially equal length; whereby a movement of a cone in the driver is parallel to the planes of rotation of the arms when an alternating current signal is applied to the driver; wherein the length of the arms is chosen to provide a predetermined resonant frequency of the loudspeaker; and wherein the predetermined resonant frequency of the loudspeaker is less than a lower cutoff frequency of the driver.
