Claim:
1. An implantable magnetic transducer arrangement for a hearing implant in a recipient patient, the arrangement comprising: an implant housing hermetically encapsulating an interior housing volume and adapted to be fixedly attached to skull bone beneath the skin of the patient; a magnetic transducer within the housing volume having: i. a plurality of pie-shaped permanent magnets arranged with alternatingly different direction magnetic polarities; and ii. one or more suspension elements resiliently coupling adjacent magnets to allow their movement relative to each other; wherein the magnetic transducer is operatively coupled to an external magnetic drive component above the skin of the patient; and wherein the magnetic transducer and the external magnetic drive component are configured to cooperate together to form an oscillating system that develops a mechanical stimulation signal to the implant housing for delivery by bone conduction of the skull bone as an audio signal to the cochlea of the patient; wherein the suspension elements include a spring membrane resiliently and directly coupling adjacent magnets.
