1. A direct bone conduction hearing aid device characterized by increased comfort and aesthetic appearance, said device comprising:

  • sound processing means for converting sound into an analog electromagnetic signal and including an output transmitter for transmitting the electromagnetic signal and being adapted to be placed supercutaneously on the skull of a hearing impaired person and having first magnetic means therein; and

    vibration generating means adapted to be implanted subcutaneously and comprising means for securing said vibration generating means subcutaneously to a skull bone of the hearing impaired person and second magnetic means (1) for cooperating with said first magnetic means to hold said transmitter in position supercutaneously on the skull of the hearing impaired person, (2) for receiving the electromagnetic signal from said transmitter of said sound processing means, and (3) for vibrating the skull bone in response to such electromagnetic signal;

    whereby, vibrations are generated subcutaneously in response to the analog electromagnetic signal and conducted through the bones of the skull to stimulate the inner ear to create the perception of sound in the hearing impaired person.
