Abstract

An implantable hearing aid system is disclosed. According to one or more of the mentioned aspects, the implantable hearing aid system comprises a charger unit which includes a coil unit having a first resonance frequency, a hearing aid and an implantable component. The hearing aid includes a rechargeable battery, an inductive coil arrangement having a second resonance frequency configured to form an inductive charging link with the coil unit to receive power signals from the charger unit. The implantable component includes an implantable coil, wherein the inductive coil arrangement may further be configured to form a transcutaneous link with the implantable coil to transmit at least one of data and power to the implantable component.

Dependent claims

An implantable hearing aid system, comprising:

a charger unit including a coil unit having a first resonance frequency,
a hearing aid, including:
a rechargeable battery,
an inductive coil arrangement having a second resonance frequency configured to form an inductive charging link with the coil unit to receive power signals from the charger unit,
a voltage decreasing converter configured to decrease a voltage of the power signals received from the charger unit for use in charging the rechargeable battery, and
a voltage increasing converter configured to increase a voltage of signals obtained from the rechargeable battery, and
an implantable component including an implantable coil, wherein the inductive coil arrangement is further configured to form a transcutaneous link with the implantable coil to transmit at least one of data and power to the implantable component, and wherein the first resonance frequency and the second resonance frequency are matched or partly matched.
