Abstract

This disclosure describes a speaker assembly suitable for use in a portable electronic device utilizing water resistant ports. The speaker assembly can have an open back that subjects a back volume of the speaker to pressure differentials within a device housing of the portable electronic device. The speaker assembly can utilize a speaker surround having a varying thickness. The varying thickness speaker surround allows the speaker to maintain an acceptable frequency response profile while limiting the travel of the diaphragm it is coupled with. The disclosure also describes how electrically conductive pathways can be integrated within a housing of the speaker assembly.
