| Abstract: |
A wearable portable entertainment and personal communication system which provides high quality sound, particularly at low audio frequencies, and which does not block or attenuate environmental sounds is disclosed. In a first embodiment, a transducer or transducer array is positioned on a wall in a sampling chamber between two cavities. One of the cavities is sealed and the other has one or more conduit members which direct the acoustic signals to one or both of the wearer's ears. In a second embodiment, both cavities have conduits, one directed to each of the wearer's ears. With either embodiment, the sampling chamber optionally can be combined with separate high frequency transducers. With both embodiments, the chambers are incorporated into a wearable garment and the transducers are connected to a source of audio signals.

It is claimed:
1. An audio system for producing high fidelity audio signals and adapted to be worn on the torso of a wearer, the audio signals including high frequency signals and low frequency signals, said audio system comprising:
- at least one housing having at least two chambers with a common wall member separating said two chambers,
- first output transducer means mounted on said common wall member,
- a source of high fidelity audio signals,
- means connecting said source of audio signals to said first transducer means for driving said transducer means and producing low frequency acoustic pressure modulation signals in said two chambers,
- conduit means for transmitting said low frequency signals from at least one of said two chambers in a direction toward at least one ear of the wearer,
- said conduit means comprising at least one tubular member having a first end connected to said housing and a second end adapted to be positioned in proximity to an ear of the wearer,
- second output transducer means positioned adjacent said second end of said conduit means,
- means connecting said source of audio signals to said second transducer means for driving said second transducer means and producing high frequency audio signals therefrom,
- a wearable member adapted to be worn on the torso of a wearer,
- said housing and conduit means being attached to said wearable member,
- wherein when said system is worn with the housing being positioned on the wearer's torso and the conduit means positioned with said second ends adjacent the wearer's ears, the system provides to the wearer a low frequency and high fidelity response which approximates that provided by conventional head phones and ear phones that cover the wearer's ears and significantly block external sounds to the ears.
