Abstract
A device with a speaker system and adapted to wear on the head of a wearer, such as a headband, is provided. Transducers are situated in a wearable device and positioned on opposite sides of the wearer's head, adjacent the ears. In one embodiment, the transducers share a common enclosure and are driven 180.degree. out of phase, so that back pressures cancel and low frequency response is enhanced. In another embodiment, two vented enclosures are provided, each with its own transducers. In other embodiments, acoustic concentrators can be incorporated to direct the audio more directly toward the wearer's ears. The speaker system is connected to or in communication with a conventional source of audio signals, such as a radio, tape player, CD player, cellular telephone or the like.
