Bone conduction hearing aid.

A bone-conduction hearing aid, particularly bone-conduction hearing aid spectacles with a magnet system held in a housing and exhibiting a permanent magnet, with a coil and an armature, held on an armature spring, of soft-magnetic material which interacts with a conductor knob which can be brought to rest against the mastoid of the user, in which arrangement the housing can be pressed against the head of the user and a support spring is held via a rubber bearing at the housing in the area of the conductor knob. To increase the difference between the useful signal and the noise signal in such a hearing aid, it is provided that the spring constant (kD1) of the support spring (8) is 0.4 N/cm at the most. <IMAGE>
