1. A sound acquisition system for a magnetic hearing aid, comprising:

  • an electromagnetic (“

    EM”

    ) transducer disposed in a housing;

    a magnetic spacer operably coupled to the EM transducer and comprising at least a first magnetic member, the EM transducer, the housing and the magnetic spacer forming external portions of the magnetic hearing aid;

    a magnetic implant configured to be placed beneath a patient'"'"'s skin and adjacent to or in a patient'"'"'s skull, the magnetic implant comprising at least a second magnetic member, the magnetic spacer and magnetic implant together being configured such that the first and second magnetic members are capable of holding the magnetic hearing aid in position on the patient'"'"'s skull over at least portions of the implanted magnetic implant, anda sound acquisition device configured to be positioned between the magnetic spacer and the magnetic implant, and to be magnetically coupled to the magnetic spacer and the magnetic implant, such that sound signals generated by the EM transducer in the hearing aid may be acquired by a sound sensor forming a portion of the sound acquisition device as the sound signals pass through the sound acquisition device into the patient'"'"'s skull, the sound sensor comprising a piezoelectric sensor.
