摘要： An external component of a prosthesis, including a first module including a functional component and first structure including magnetic material. The first module is configured to be retained against skin via a magnetic field at least partially generated by a magnet implanted in a recipient that interacts with the magnetic material of the first structure, the first module including a skin interfacing surface configured to interact with skin of the recipient when the first module is retained against the skin of the recipient, a second module including a second structure including magnetic material configured to enhance magnetic retention of the external component to skin of a recipient, wherein the second module is removably attached to the first module and visible from an outside of the external component when the second module is attached to the first module and when viewed from a side opposite the skin interfacing side.

摘要： Presented herein are transcutaneous bone conduction devices having seismic mass actuators that impart vibration to a recipient's skull via relative movement of an associated seismic mass and a coupling mass. The vibration may be generated based on sound signals received at one or more microphones that are suspended from the seismic mass.

摘要： A percutaneous bone conduction auditory prosthesis utilizes a multipole magnetic coupling system to secure the external device to an abutment that is secured to the skull of a recipient. With the multipole magnetic coupling system, a very strong retention force is formed between the device and the abutment. The multipole magnetic coupling system can include a complex array of exposed poles, such that the retention forces are coordinated with a mating abutment.
