Abstract
An open audio device with a housing that is configured to be worn on the torso and an acoustic transducer carried by the housing, the acoustic transducer configured to either radiate sound outwardly of the housing or convert received sound into an electrical signal. A structure is coupled to the housing. The structure is proximate to the acoustic transducer. The structure is constructed and arranged to inhibit radiated sound or received sound from being interrupted by a flexible sheet material, such as clothing, located over the housing.
