Abstract
A speaker may be configured with at least one diaphragm positioned proximal to and separated from an array of magnets. The diaphragm may consist of a substrate and at least one patterned electrically conductive trace with a portion of the diaphragm knurled to provide a ridge extending a height above the diaphragm that is at least twice a thickness of the diaphragm.

An apparatus comprising a diaphragm positioned proximal to and separated from a first array of magnets, the diaphragm comprising a substrate attached to at least one patterned electrically conductive trace, a portion of the diaphragm knurled to provide a ridge extending a height above the diaphragm that is at least twice a thickness of the diaphragm.
An apparatus comprising a diaphragm positioned proximal to and separated from a first array of magnets, the diaphragm comprising a substrate attached to at least one patterned electrically conductive trace, a portion of the diaphragm knurled to provide a plurality of ridges each extending a height above the diaphragm that is at least twice a thickness of the diaphragm, the thickness measured from a plane dissecting the diaphragm towards the first array of magnets, the thickness and height being parallel.
A method comprising:
- positioning a diaphragm proximal to and separated from a first array of magnets, the diaphragm comprising a substrate attached to at least one patterned electrically conductive trace;
- and
- knurling a portion of the diaphragm to provide a ridge extending a height above the diaphragm that is at least twice a thickness of the diaphragm.
