Claim Text:
1. An electromagnetic transducer, comprising: first and second assemblies connected together by a flexible component that flexes upon exposure of the transducer to energy, wherein the first assembly is configured to generate a dynamic magnetic flux, the second assembly is configured to generate a static magnetic flux, the assemblies are constructed and arranged such that a first radial air gap is located between the first assembly and the second assembly and such that during operation of the transducer the static magnetic flux flows through the first radial air gap, whereby the dynamic magnetic flux and the static magnetic flux generate relative movement between the first assembly and the second assembly, a second radial air gap is located between the first assembly and the second assembly, and a reluctance at the first of the two radial air gaps is substantially the same as a reluctance at the second of the two radial air gaps through the range of movements of the second assembly relative to the first assembly.
