Abstract
Presented herein are low-power active bone conduction devices that comprise an actuator that is subcutaneously implanted within a recipient so as to deliver mechanical output forces to hard tissue of the recipient. The low-power active bone conduction devices include an energy recovery circuit configured to extract non-used energy from the actuator and to store the non-used energy for subsequent use by the actuator. The low-power active bone conduction devices may also include a multi-bit sigma-delta converter that operates in accordance with a scaled sigma-delta quantization threshold value to convert received signals representative of sound into actuator drive signals.
