Abstract

An active noise reducing headset has a high compliance driver (13) having a diaphragm (14). A structure (15) limits the maximum excursion of the diaphragm (14) so that the voice coil does not escape the air gap. Indentations (17) in the diaphragm (14) may be provided to prevent unrecoverable diaphragm collapse.
