Transducer arrays, e.g. pairs of speakers, are situated in a wearable garment, headband, or the like and positioned on opposite sides of the wearer's head. In one embodiment, the transducer arrays share a common enclosure and are driven 180° out of phase, so that back pressures cancel and low frequency response is enhanced. In another embodiment, two open-ended enclosures are provided, each with its own transducer array. In another embodiment, linear arrays of transducers are provided with appropriate time-delays between the audio signals. 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. | |
