Zusammenfassung:	A balanced armature receiver including a motor with a yoke for retaining magnets and fastening to an armature are disclosed. The yoke includes a close-ended wall structure formed of a soft magnetic material having multiple folded corners defining an armature passage. A first magnet retaining wall portion of the yoke is arranged in parallel with, and opposite, a second magnet retaining wall portion, wherein at least a portion of the first magnet retaining wall portion has a reduced thickness relative to other wall portions of the close-ended wall structure. The armature is connected to the reduced thickness portion of the first magnet retaining wall portion, thereby reducing an overall z-axis dimension of the motor.
