Patent abstract
A transducer assembly may include a first transducer having a first front volume, a first back volume and a first port acoustically coupled to the first front volume; and a second transducer having a second front volume, a second back volume and second port acoustically coupled to the second front volume. The first front volume and the second front volume are acoustically coupled to increase the effective back volume of both the first transducer and the second transducer. An optional signal processing circuit may be used to control the output of the first transducer based upon a signal received from the second transducer.
