Application of Ferrofluids as an Acoustic Transducer Material.

Abstract

Application of ferrofluids to electroacoustic transduction is described. Properties of ferrofluids relevant to the problem are given, and the basic equations and derivations are developed. Power transfer calculations are performed for a piston-type transducer, and a conceptual design is offered for a toroidal configuration. (Author)
