Abstract
The invention relates to various rotational action audio transducer embodiments having a diaphragm structure including a single or multiple diaphragms. A diaphragm suspension rotatably mounts the diaphragm structure to a base structure. In some embodiments, the diaphragm suspension may be made from soft and/or damped materials. In some embodiments, the location of an axis of rotation of the diaphragm is determined based on a node axis of the diaphragm. A transducing mechanism of the audio transducer cooperates with the moving diaphragm to transduce sound. The mechanism may comprise a moving magnet design in some embodiments, or a moving coil design in others.
