ABSTRACT:
Both water intrusion and wind noise issues are addressed with an audio porting assembly including a single frame (102) having a speaker cavity (110) and a microphone cavity (112) formed therein. An opening (114) formed within the frame (102) between the speaker cavity (110) and the microphone cavity (112) provides a path for indirect porting from the speaker cavity into the microphone cavity. A unitarily molded membrane (104) provides a seal over the frame (102).
