Abstract
A support member for a voice coil former in an audio transducer is described. The support member comprises a bridge between the inner surface of the voice coil former and a radiating surface, such as a diaphragm or cone, which is disposed in the center of the voice coil former. The support member provides added rigidity to reduce wobble during operation of the transducer.
