Abstract
An electro-acoustic driver includes a diaphragm formed of a compliant material, a bobbin configured to hold a winding of an electrical conductor and a housing having a housing axis that is substantially coaxial with the bobbin. The diaphragm is fixed to one end of the housing and has a substantially planar shape when the diaphragm is at rest. A stiffening element is fixed to an inner region of a surface of the diaphragm. A motion of the bobbin along a bobbin axis generates a movement of the inner region of the diaphragm to thereby generate an acoustic signal that propagates from the diaphragm.
