A direct bone conduction hearing aid system for generating direct bone conduction vibration includes a vibrator that is placed in an implanted vibrator unit and an implanted energy-receiving unit that has an energy-receiving inductive coil. A vibrator supply cable connects the implanted energy-receiving unit to the implanted vibrator unit. A mounting arm connects the implanted vibrator unit with an anchoring fixture that is anchored to the skull bone through the skull bone surface. The implanted vibrator unit is positioned in the mastoid cavity. The mounting arm is positioned laterally to the implanted vibrator unit and the bone fixation portion of the anchoring fixture.
