1. An acoustic receiver comprising:
a first receiver subassembly comprising:
a bottom housing plate; and
a motor disposed on the bottom housing plate, the motor including a coil having a passage, a yoke retaining first and second magnets, and a reed having a portion extending through the passage and between the magnets;
a second receiver subassembly comprising a closed-ended housing sidewall having a first open end and a second open end, the first receiver subassembly and the second receiver subassembly are separate components,
the bottom housing plate disposed over and fastened to the first open end of the closed-ended housing sidewall to form at least a portion of a receiver housing, wherein the closed-ended housing sidewall is disposed about the motor;
a diaphragm located in the receiver housing, the diaphragm separating an interior of the receiver housing into a front volume and a back volume, wherein the motor is disposed in the back volume;
a link interconnecting a movable portion of the reed with a movable portion of the diaphragm,
wherein the reed is movable between the first and second magnets in response to an excitation signal applied to the coil.
