摘要：Electromechanical transducer for implantable hearing aids. The transducer has ahermetically sealed and biocompatible housing, in which a wall is designed as amembrane that can oscillate, and which forms a heteromorphic connecting elementtogether with a piezoelectric ceramic disk. Mechanical oscillations of the housingmembrane are coupled to the middle ear or inner ear of the user by a mechanically rigidelement attached in the central area of the membrane. This element is configured as abow, so that in positioning the transducer housing from the direction of the mastoidadjoining the tympanic cavity, it acts as an artificial anvil to which coupling elements canbe attached for mechanically transmitting oscillations of this artificial ossicle to the innerear. Various coupling elements can be used, which correspond to the respective individualpathological situation. The application of the entire transducer system can be performedthe operating surgeon having an unobstructed view, without extensive, space-creatinginterventions in the anatomical conditions of the middle ear.
