Abstract
An implantable unit of a transcutaneous hearing device and a transcutaneous hearing device comprising the same are disclosed. The implantable unit comprises a receiver element configured to wirelessly receive an electromagnetic wave, a rectifier element configured to generate upper and lower half waveforms of the electromagnetic wave, and a vibrator element configured to electromechanically produce vibration using the half waveforms of the electromagnetic wave. The vibrator element comprises a first vibrator and a second vibrator. The first vibrator is configured to be driven by the upper half waveform of the electromagnetic wave, and the second vibrator is configured to be driven by the lower half waveform of the electromagnetic wave.

An implantable unit configured to be used in a transcutaneous hearing device, comprising:
- a receiver configured to wirelessly receive an electromagnetic wave,
- a rectifier configured to generate upper and lower half waveforms of the electromagnetic wave, and
- a vibrator configured to electromechanically produce vibration using the half waveforms of the electromagnetic wave,
- wherein the vibrator comprises a first vibrator configured to be driven by the upper half waveform of the electromagnetic wave and a second vibrator configured to be driven by the lower half waveform of the electromagnetic wave,
- the rectifier comprises a first diode in a path from the receiver to the first vibrator and a second diode in a path from the receiver to the second vibrator, and
- the first diode and the second diode are connected with mutually opposite polarity between the receiver and the vibrator.
