1. A miniature receiver comprising:
- a housing defining a chamber of the miniature receiver suitable for use in a hearing aid;
a motor assembly including a magnet assembly and an armature having at least a first leg and a second leg extending substantially parallel in a first direction; and
a diaphragm operationally attached to the armature,wherein the motor assembly is attached at an end face thereof to a movable suspension structure to allow a free end of the motor assembly opposite to the end face thereof to move inside the chamber,wherein the movable suspension structure is attached to an inner wall of the housing at a single attachment point,wherein the motor assembly is configured for pivotal movement around a pivot axis that is substantially perpendicular to the first direction,wherein the movable suspension structure is configured for decoupling the mass of the motor assembly from the housing, the movable suspension structure is configured to isolate movement of the motor assembly from the housing, and the movable suspension structure is configured for reducing vibration transfer from the miniature receiver.

11. A method of reducing vibrations in a receiver, the method comprising the steps of:
-
providing a housing defining a chamber of the miniature receiver suitable for use in a hearing aid, providing a motor assembly including a magnet assembly and an armature having at least a first leg and a second leg extending substantially parallel in a first direction, providing a diaphragm, providing a movable suspension structure, attaching the diaphragm to the armature, attaching the motor assembly at an end face thereof to the movable suspension structure to allow a free end of the motor assembly opposite to the end face thereof to move inside the chamber, and attaching the movable suspension structure to an inner wall of the housing at a single attachment point such that the motor assembly is configured for pivotal movement around a pivot axis that is substantially perpendicular to the first direction, wherein the movable suspension structure is configured for decoupling the mass of the motor assembly from the housing, the movable suspension structure is configured to isolate movement of the motor assembly from the housing, and the movable suspension structure is configured for reducing vibration transfer from the miniature receiver.
