Abstract
A surround for supporting a diaphragm used to create acoustic waves includes a plurality of first rib sections extending away from the diaphragm and a second rib section having a zigzag pattern and being secured to an end of each of the first rib sections. As the diaphragm starts moving away from a home position in an intended direction of travel which is substantially perpendicular to a plane in which the diaphragm lies when the diaphragm is in the home position, the zigzag pattern of the second rib section starts to straighten out.
