ABSTRACT:
The present invention relates to a hearing aid receiver (10) having a coil (12) with a tunnel (14) therethrough, a magnetic structure (16) having a central magnetic gap (18), an armature (20), and a fluid (30, 32) with a viscosity greater than air to provide shock protection to the receiver (10). The tunnel (14) and the magnetic gap (18) collectively form an armature aperture (28). The armature (20) extends through the armature aperture (28). The fluid (30, 32) lies within the armature aperture (28).
