Disclosed examples generally include methods and apparatuses related to microphone units, such as may be found in implantable medical devices (e.g., cochlear implants). Microphone units generally include a microphone element connected to a chamber having a concave floor with the chamber covered by a membrane. Microphone units can be configured to produce an output based on pressure waves (e.g., sound waves) that reach the membrane. In an example, a microphone unit has a pressurized gas within the chamber below the membrane such that, while in a static state, the membrane deflects away from the chamber floor.

A bone conduction device includes split high-frequency and low-frequency actuators. The frequency response of the low-frequency actuator can be restricted to the lower range of hearing frequencies to improve performance. The high-frequency actuator can be implanted under tissue close to the cochlea to improve transmission efficiency, since high-frequency vibrations suffer greater attenuation.

Bone conduction devices utilizing multiple actuators

An implantable component, such as by way of example, an implantable component of a transcutaneous bone conduction device, the implantable component comprising a piezoelectric transducer, wherein the implantable component is configured to temporarily prevent the piezoelectric transducer from moving inside the housing while the housing is implanted in the recipient.

Shock and impact management of an implantable device during non use

A device including a cochlear implant electrode array and an apparatus configured to sense a phenomenon of fluid in a cochlea, wherein the apparatus and the electrode array are a single unit.

Implantable components configured to be secured to a recipient with a bonding agent are presented herein. The implantable components are configured to be implanted adjacent to a recipient's bone and/or tissue and have a surface for attachment to the bonding agent.
