TRANSDUCER
First Claim
1. A transducer, comprising:
- a driven element;
a magnet assembly coupled to said driven element, said magnet assembly including;
a first magnet having a first magnetic pole and a second magnetic pole;
a second magnet having a first magnetic pole and a second magnetic pole, said first magnetic pole of said first magnet and said first magnetic pole of said second magnet being proximate to each other and facing each other thereby defining a first magnetic zone therebetween, said first magnetic poles all being similar, and said second magnetic poles all being similar; and
a ferrous member coupling a substantial amount of the magnetic field emanating from said second magnetic poles and directing the substantial amount of the magnetic field to a gap between the ferrous member and the first magnetic zone.

Abstract
A transducer including a driven element and a magnet assembly. The magnet assembly is coupled to the driven element and includes a first and a second magnet, and a ferrous member. Each of the magnets have a first and second magnetic pole. The first magnetic pole of the first magnet and the first magnetic pole of the second magnet being proximate to each other and facing each other thereby defining a first magnetic zone therebetween, the first magnetic poles being similar, and the second magnetic poles being similar. The ferrous member couples a substantial amount of the magnetic field emanating from the second magnetic poles and directing the substantial amount of the magnetic field to a gap between the ferrous member and the first magnetic zone.
