1. An air pulse generator for providing a high frequency chest wall oscillation therapy to a patient, the air pulse generator comprising:
- a housing having a front wall and a back wall defining an interior region, the front wall of the housing having first and second air openings;
a shell having a front portion and a back portion defining an air chamber, the front portion of the shell having first and second air ports in communication with the air chamber, the first and second ports being aligned with the first and second openings when the shell is mounted within the interior region of the housing, wherein air pulses from the air chamber are communicated to the patient through the first and second air openings and the first and second air ports to provide the high frequency chest wall oscillation therapy to the patient, wherein the front and back portions of the shell define first and second diaphragm openings on the opposite sides of the air chamber; and
first and second diaphragm assemblies positioned over the first and second diaphragm openings, respectively.
