Abstract
A bone conducting hearing aid comprises a housing adapted to be pressed against a head of a user and a magnetic system held in the hearing aid housing, The magnetic system includes a permanent magnet, a coil, an armature of a soft magnetic material and a spring holding the armature. A conductor button is arranged to move with the armature, the conductor button being shaped to be brought into contact with the mastoid bone of the user's head, and a rubber bearing having a predetermined elastic constant holds a support spring for the conductor button on the hearing aid housing. To increase the difference between the useful signal and the spurious signal received by the hearing aid, the support spring has an elastic constant not exceeding 0.4 N/cm.
