Described is a personal on-demand audio entertainment system with a base unit attached to a personal computer or other source, a headphone unit and a remote control unit. The base unit transmits digital audio content to the headphone unit using infrared, radio frequency, magnetic or electromagnetic coupling. These data are stored in solid-state memory within the headphone unit. In the headphone unit, the stored digital audio content is converted to analog audio signals, amplified and sent to transducers for conversion to audio signal for the listener during playback. The system is designed such that playback may occur during the downloading process. The remote control unit also uses infrared, radio frequency, magnetic or electromagnetic coupling for communication to the headphone unit. This communication is made using a different channel and does not interfere with the audio data downloading. The remote control unit has a display and allows for control of player functions and modification of audio characteristics such as volume, bass, treble, balance, etc. |

DETAILED DESCRIPTION A principal object of the present invention is to provide an audio entertainment device that allows wireless operation.
A second object of the present invention is to provide an audio entertainment device that allows wireless downloading of audio content from a personal computer or other digital audio data source.
Another object of the present invention is to provide an audio entertainment device that allows wireless downloading of audio content using infrared, radio frequency, magnetic coupling or other electromagnetic means.
Another object of the present invention is to provide an audio entertainment device that allows wireless downloading of audio content simultaneously during playback of the audio content.
Another object of the present invention is to provide an audio entertainment device where conversion from digital to audio format is done within the headphone unit thereby reducing impedance losses typically experienced in wired headphone units.
Another object of the present invention is to provide an audio entertainment device with a separate handheld remote unit to allow control of the downloading and audio characteristics.
A still further object of the present invention is to provide an audio entertainment device that may be operated with a standard audio source as a wireless headphone unit.
These objects are achieved using a system with a headphone unit, a remote control unit and base unit attached to a personal computer, a home entertainment unit such as a DVD player or TV or other source.
The base unit transmits digital audio content to the headphone unit using infrared, radio frequency, magnetic coupling or other electromagnetic means.
These data are stored in solid-state memory within the headphone unit.
In the headphone unit, the stored digital audio content is converted to analog audio signals, amplified and sent to transducers for conversion to audio signal for the listener during playback.
The system is designed such that playback may occur during the downloading process
