Abstract
A stabilizer for use in stabilizing a diaphragm of an audio device, such as a microphone transducer or a speaker driver. The stabilizer is configured to be attached to the diaphragm to provide stability to the diaphragm, which may be in the form of one or more of counteraction to asymmetric movement about the center of mass of the voice coil; counteraction to rotation in a direction perpendicular to the desired axial motion of the diaphragm; and additional nonlinear stiffness for mechanical limiting of the diaphragm in the axial direction, which may assist in preventing large excursions of the diaphragm from atypical sources, such as drop, shock, etc.
