US 6,768,230 B2 · Multiple magnet transducer

Abstract

A dynamic magnet system, particularly useful for electrical generation, employs multiple magnets in polar opposition to each other and having a critical angle of displacement from a horizontal static position of less than 1 degree, to induce an electrical signal in one or more surrounding coils. The magnets interact with each other to yield multiple modes of oscillation and a greater range of response to applied inputs than is achievable with a single magnet system. A lubricant for the magnets is preferably a ferrofluid that establishes a static coefficient of friction between the magnets and their support structure less than about 0.02, with a viscosity less than 10 centipoise. The magnets can be oriented for movement in a primarily horizontal direction and are adaptable to numerous different kinds of support structures, including ring-shaped.

Dependent claims

A dynamic magnet system, comprising:

a support structure,
an even number of magnets oriented in polar opposition to individually move relative to said support structure along a common axis,
said support structure providing an unobstructed magnet movement path between said magnets,
a conductor oriented with respect to said support structure and magnets so that movement of said magnets induces an electrical signal in said conductor, and
an operating system powered by said signal.
