Abstract
The hearing aid system has a sound-to-vibration conversion circuitry including a microphone system, an electronic amplifier and a vibrator. A housing accommodates the vibrator. The vibrator is connected to an abutment that goes through the skin. The abutment is connected to a fixture that is anchored in the skull bone. The sound-to-vibration conversion circuitry has an A/D converter that converts an analogue microphone signal into a digital signal.
