| 摘要 |
The invention relates to a hearing instrument comprising an audio signal source (28), an audio signal processing unit (34) for processing the audio signals provided by the audio signal source and an implantable stimulation assembly (18) for stimulating the round window membrane (24) of a patient according to the processed audio signals, wherein the stimulation assembly comprises an electromechanical actuator (20) to be driven according to the processed audio signals, a contact element (62) to be mechanically driven by the actuator and to be in direct contact with the round window for making the round window membrane vibrate according to the processed audio signals, and a support element (68, 168) comprising a proximal portion (70) to be fixed at the cortical part of the patient's temporal bone (72) and a distal portion (66) angled with regard to the proximal portion, wherein the actuator is provided at a distal end of the distal portion of the support element, and wherein the contact element is driven by a distal end of the actuator in an axial direction (84) with regard to the distal portion of the support element. |
