Abstract
The invention relates to an electronic compass adapted for providing users with an audible indication of direction. The compass includes a housing assembly having a speaker for providing a user with information concerning the orientation of the housing assembly relative to the earth's magnetic field. The compass further includes a Hall Effect detector for determining the orientation of the housing assembly relative to the Earth's magnetic field and a translator for translating the orientation data relating to the position of the housing assembly relative to the earth's magnetic field into an auditory signal which is transmitted to the speaker assembly for translation into an audible signal providing a user with audible instructions regarding the orientation of the housing assembly.
