    Abstract: An apparatus configured to be implanted within a portion of a recipient's body includes a fixation element having a socket and a transducer configured to be received by the socket. The transducer includes a first end portion configured to transmit signals to and/or receive signals from a target portion of the recipient's body. The transducer further includes a second end portion opposite to the first end portion, the first and second end portions spaced from one another along a center longitudinal axis of the transducer. The transducer further includes a surface at the first end portion or between the first and second end portions, the surface configured to be in mechanical communication with the socket with the center longitudinal axis of the transducer extending through the socket. The transducer is configured to be rotated such that an angular orientation of the center longitudinal axis relative to the socket is controllably adjusted.

    Abstract: 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.

    Abstract: An apparatus includes at least one vibration-generating actuator having a coupler configured to be in mechanical communication with a fixture, at least one mass spaced from the coupler, and at least one non-planar piezoelectric element in mechanical communication with the coupler and the at least one mass. The at least one non-planar piezoelectric element is configured to oscillate the at least one mass relative to the coupler in response to received electric voltage signals. The fixture and the at least one actuator can be configured to be implanted on or within a recipient's body, and the fixture can be configured to transmit the vibrations to the recipient's body such that the vibrations evoke a hearing precept by the recipient.

    Abstract: An assembly is provided which includes a package and a printed circuit board. The package includes a housing bounding a region and an acoustic sensor within the region. The housing includes a base with a first hole. The sensor is configured to generate signals indicative of sound received by the sensor through the first hole. The printed circuit board is in mechanical communication with the base and includes a second hole aligned with the first hole such that sound received by the second hole propagates through the first hole to the sensor. The printed circuit board further includes an electrically conductive layer, at least a portion of which extends across the second hole and is configured to allow the sound to propagate through the second hole and to at least partially shield the region containing the sensor from electromagnetic interference.
