Abstract: The invention relates to a vibration module for placing on an eardrum, which vibration module has a flat sound transducer and an eardrum contact mold for contacting the eardrum.

Abstract: An electro-acoustic implant comprising an elongate electrode carrier having a plurality of stimulation electrodes that can be introduced into a cochlea and comprising a flat sound transducer that is excitable to vibrate at least regionally by applying a voltage, with the sound transducer being configured such that it is arrangeable in, on and/or in front of a round window or an oval window or a surgically created third window of an ear and/or in a round window niche of an ear, covering the corresponding window at least partially or completely, such that vibrations of the sound transducer effect sound vibrations through the corresponding window, with the elongate electrode carrier extending through a surface of the flat sound transducer that extends, when the sound transducer is arranged in front of the corresponding window, at least partially over the corresponding window.

Abstract: The invention relates to a sound transducer for producing sound vibrations, which can be inserted in an ear and can be used in particular for an implantable hearing aid. The sound transducer has at least one carrier layer and at least one piezoelectric layer, as a result of which a deflection via a bimorph principle is achieved, or a deflection can be detected by picking up a voltage.
