ABSTRACT:
A portable, wearable personal audio system which includes an acoustic sample chamber and an acoustically transparent ear insert member. A tubular member transmits the audio from the sample chamber and module to the ear canal. An additional transducer, preferably made from a piezoelectric material, can be provided in the ear insert member or at the outer end of the tubular member. An electronics mechanism is preferably supplied as part of a behind-the-ear module or as part of the temple of a pair of eyeglasses. Stereo systems require separate systems for each ear. A quick exchange adapter mechanism is provided to connect the eyeglasses with a behind-the-ear module. A Velcro-type fastener or magnetic fastener mechanism connects the end of the eyeglasses to the module.
