Patent ID: 7747032

Claim:
A transducer assembly comprising: a first housing enclosing a first transducer, the first housing defining a first front volume, a first back volume and a first port acoustically coupled to the first front volume, the first housing further defining a first aperture extending through the first housing and communicating with the first back volume; and a second housing enclosing a second transducer, the second housing being constructed so as to be separate and self-contained with respect to the first housing, the second housing defining a second front volume, a second back volume and a second port acoustically coupled to the second front volume, the second housing further defining a second aperture extending through the second housing and communicating with the second back volume; wherein, the first housing and the second housing are coupled together such that the first aperture at least partially aligns with the second aperture to couple the first back volume and the second back volume to provide an enlarged back volume in comparison to either the first back volume or the second back volume, separately, wherein the first transducer is a receiver and the second transducer is a microphone.
