Definitions

  • the invention relates to a hearing aid having a tympanic module and a hearing gear module, wherein the eardrum module in contact with the drum shell of a person can be arranged and the ear canal module in the auditory canal of the person can be arranged.
  • Eardrum contact hearing aids create a sound impression on the wearer by exerting a force on the eardrum with direct mechanical contact. This anlie at least partially on the eardrum ing force leads to a deformation that is transmitted to the ossicular chain and so penetrates to the inner ear. Compared with a classic hearing aid, which transmits the sound to the eardrum via airborne sound, it can achieve higher efficiency and a flatter frequency response.
  • a motor element acts on the eardrum via a mechanical connection. This is realized by a structure which contains the actuator and which is directly connected to the eardrum. lies. This structure should be light in order not to cause an unpleasant feeling of pressure or even pain due to its inertia during movements of the head.
  • eardrum module Since the eardrum is very sensitive and deep in the narrow auditory canal, it should be introduced or removed for safety reasons only by a specialist and otherwise remain on the eardrum.
  • Object of the present invention is to provide a hearing aid that can be brought into contact with the eardrum, but with the drum fur in contact with components can be easily configured and the eardrum module is still reliably supplied with signals and energy.

  • the dimensions can be individually adapted to a specific person. If the eardrum module to be produced as standard, so the dimensions of the eardrum module can be adapted to average adult adult persons. If the eardrum module is intended for children, its dimensions may be adjusted to the average size of children in the appropriate age group. The same applies to the Ear canal module whose dimensions can also be individually geared to the hearing a particular person or can be adapted to average dimensions.

This loading mobility is preferably limited at best by a stiffness of the at least one cable. According to the invention, the eardrum module and the ear canal module are electrically contacted with each other via the at least one cable.
  • the eardrum module Because the eardrum module is separate from the eardrum module and is connected to it only by means of a cable, the eardrum module exerts a force on the eardrum only on the basis of its inertia. However, since many components of the hearing aid in the ear canal module can be arranged, the mass of the eardrum module can be kept small, so that the force applied to the eardrum inertial force is small.
  • the ear canal module may preferably be placed deep in the ear canal.
