Abstract
A panel audio loudspeaker includes an actuator module. The actuator module includes an intermediate layer. The intermediate layer has a voice coil connected to the intermediate layer at a first surface. The actuator module includes a magnet assembly including a plurality of magnets. At least one pair of magnets are separated by an air gap. The actuator module includes a frame connected to the intermediate layer at the first surface, one or more springs connected to the frame and suspending the magnet assembly relative to the frame so that the voice coil extends at least partially into the air gap, and a spacer connected along a portion of the intermediate layer at a second surface of the intermediate layer opposite the first surface. A stiffness of the spacer at a region of connection to the intermediate layer is less than a stiffness of the intermediate layer at the connection portion.
