Claim 0:
1. A speaker mounting assembly comprising:
a front panel having a front side, a rear side, and at least three sound openings extending between the front side and the rear side, with support members extending across each of the openings, wherein the rear side of the front panel has interface surfaces adjacent the openings;
at least three planar magnetic drivers (PMDs) each being associated with a respective sound opening of the at least three sound openings in the front panel, each PMD comprising at least one front magnet, one or more rear magnets, a diaphragm arranged between the rear and front magnets, and a PMD structure plate having a magnet mounting surface and lateral mounting flanges, wherein the magnet mounting surface and the mounting flanges have a first side that faces in a direction of the front panel and a second side that faces away from the front panel, wherein the one or more rear magnets are arranged on the first side of the magnet mounting surface, wherein the diaphragm extends between the mounting flanges, and wherein the mounting flanges are positioned at a distance from the magnet mounting surface to accommodate the one or more rear magnets between the diaphragm and the first side of the magnet mounting surface;
at least three rear thermal plates each being associated with a respective PMD structure plate of the at least three PMDs, each rear thermal plate comprising lateral mounting flanges attached to a frame, wherein the frame and the mounting flanges have a first side that faces in the direction of the front panel and a second side that faces away from the front panel; and
a thermal spreader plate designed as a frame forming an opening, the frame having a first side that faces in the direction of the front panel and a second side that faces away from the front panel, with relief surfaces formed on the first side of the frame adjacent the opening of the thermal spreader plate;
wherein the PMD structure plates are mounted to the front panel, the rear thermal plates are mounted to the PMD structure plates, and the thermal spreader plate is mounted to the rear thermal plates;
wherein the interface surfaces of the rear side of the front panel interface with the first sides of the mounting flanges of the PMD structure plates;
wherein the second sides of the magnet mounting surfaces of the PMD structure plates interface with the first sides of the frames of the rear thermal plates, and the second sides of the mounting flanges of the PMD structure plates interface with the first sides of the mounting flanges of the rear thermal plates; and
wherein the second sides of the mounting flanges of the rear thermal plates interface with the relief surfaces formed on the first side of the frame of the thermal spreader plate.
