Abstract
A tactile vibration driver for use in a headphone includes a support structure, at least one suspension member suspending at least one rigid member relative to the support structure, and a plurality of magnetic members attached to the at least one rigid member and configured to drive oscillating movement of the at least one rigid member and the at least one suspension member so as to produce tactile vibrations during operation of the tactile vibration driver. An audio system includes the tactile vibration driver. A method of operating an audio system includes driving a plurality of magnetic members attached to a rigid member of the tactile vibration driver to cause oscillations of the plurality of magnetic members and the rigid member relative to a suspension member and producing tactile vibrations responsive to receipt of an electrical signal.
