1. A thin acoustic transducer comprising:
an upper portion comprising:
a diaphragm;
a first voice coil on a first side of the upper portion, wherein the first voice coil is disposed behind the diaphragm and proximate to a first extreme side of the diaphragm; and
a second voice coil on a second side of the upper portion, wherein the second voice coil is disposed behind the diaphragm and proximate to a second extreme side of the diaphragm; and
an enclosure the upper portion is inserted into, wherein the enclosure comprises:
a first magnetic motor assembly on a first side of the enclosure, wherein the first magnetic motor assembly is disposed behind the diaphragm and proximate to the first extreme side of the diaphragm;
a second magnetic motor assembly on a second side of the enclosure, wherein the second magnetic motor assembly is disposed behind the diaphragm and proximate to the second extreme side of the diaphragm; and
an electronics system, wherein the electronics system is disposed behind the diaphragm and between the first magnetic motor assembly and the second magnetic motor assembly;
wherein the upper portion that includes the diaphragm, the first voice coil, and the second voice coil is a component that is separately assembled from the enclosure and then inserted into the enclosure, such that the first voice coil is at least partially disposed within a first gap of the first magnetic motor assembly, and the second voice coil is at least partially disposed within a second gap of the second magnetic motor assembly.
