Abstract
A receiver module configured to be seated within an ear canal and optimized for simultaneously inflating an inflatable membrane while generating acoustic waves transmitted to a user. The inflatable membrane can be used to secure the receiver module within the bony portion of the ear canal of the user. A multi-layer valve system and method of assembly are disclosed for a valve system to harvest static pressure from acoustic waves generated within the receiver and direct the increased pressure toward the inflatable membrane to inflate the membrane. The multi-layer valve system can be used to prevent a back flow of air and thereby maintain a static pressure differential between ambient air drawn in through an air ingress port and air forced into the inflatable membrane through an air egress port.
