Abstract:
A transducer assembly including a transducer enclosure having an enclosure wall separating a surrounding ambient environment from an encased space, and a transducer module positioned within the encased space. The transducer module has a module wall that divides the encased space into an exterior chamber and an interior chamber and defines a fluid port between the exterior chamber and the interior chamber, the exterior chamber is between the module wall and the enclosure wall, the interior chamber is between the module wall and a sound radiating surface positioned within the transducer module, and the interior chamber is acoustically coupled to an acoustic port to the surrounding ambient environment. The enclosure wall is movable relative to the module wall and movement of the enclosure wall causes ejection of a fluid out of the interior chamber to the ambient environment.
