Abstract
A receiver includes an acoustic module and a coil module. The acoustic module includes a first housing, a plurality of magnets, and an armature. The armature is disposed within the first housing and extends between the plurality of magnets. The coil module is coupled to the acoustic module, is physically separate from the acoustic module, and includes a second housing and a coil. The coil disposed within the second housing and does not surround the armature. The coil is excitable by an electrical current representative of acoustic energy and excitation of the coil produces a magnetic flux path which moves the armature.
