| 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. The ear insert stabilizes and secures the tubular member in the ear canal. One or more surfaces of the ear insert member can be coated with a perforated flexible material. 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.

It is claimed:
1. A portable, wearable communication and entertainment audio system comprising:
- a housing;
- an audio source positioned in said housing, said audio source comprising a chamber with a closed first cavity, a second cavity and a first transducer member positioned on a common wall separating the first and second cavities;
- tubular conduit member in communication with said second cavity for transmitting audio from said audio source to the ear of a wearer;
- ear insert member attached to said conduit member, said ear insert member being made from an acoustically transparent non-dissipating material which allows substantially full acoustic transmission therethrough; and
- a second transducer member, said second transducer member being an output transducer and being positioned on said ear insert member;
- wherein when said ear insert member is positioned in the ear of a wearer, audio from said audio source is transmitted to the wearer, while at the same time audio from external environmental sources is also transmitted to said wearer through said ear insert member.
