<p>A wearable speaker system which provides improved quality audio response and which does not interfere with the wearer's activities or block environmental sounds is disclosed. Transducer arrays, e.g. pairs of speakers (30', 32') 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 degrees 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 (42, 44) 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.</p> |
