Abstract
An apparatus includes an enclosure capable of receiving a transducer for converting electrical signals into audible signals. The apparatus also includes one or more structures within the enclosure defining one or more channels, each channel having one end located within the enclosure and another end that is external to the enclosure. The apparatus also includes an acoustic resistive element located in the one of the one or more structures, the acoustic resistive element being capable of changing the acoustic characteristics of at least one of the one or more channels within the enclosure.
