Claim Text:
1. A sound processor, comprising: a housing defining an interior and an exterior with a circular mounting structure; sound processor circuitry within the housing; a removable external element, removably mounted to the circular mounting structure such that the external element is rotatable relative to the circular mounting structure when mounted to the circular mounting structure, including a knob and a first plurality of magnets associated with the knob, each movable element magnet defining a north/south orientation and at least two of the movable element magnets have different north/south orientations; and an internal control device within the housing, operably connected to the sound processor circuitry, and including a control device rotatable member and a second plurality of magnets, each internal control device rotatable member magnet defining a north/south orientation and at least two of the internal control device rotatable member magnets have different north/south orientations; wherein the number of magnets in the first plurality of magnets is different than the number of magnets in the second plurality of magnets; wherein the external element, when mounted to the circular mounting structure and oriented in the predetermined manner relative to the internal control device, is magnetically coupled to the internal control device rotatable member such that rotation of the external element results in corresponding rotation of the internal control device rotatable member.
