Patent ID: 7107074

Claim:
A computer system with a wireless signal transmitter module for transmitting a wireless signal, which comprises: a sound effect interface connected to the computer system for output of an audio signal; and a wireless audio signal transmitter module coupled to the sound effect interface, the wireless audio signal transmitter module receives the audio signal through the sound effect interface, the wireless audio signal transmitter module including (a) an audio signal processing circuit for receiving the audio signal from the sound effect interface and generating a wireless signal, (b) a signal modulation circuit coupled to the audio signal processing circuit for modulating the wireless signal received therefrom, (c) an enciphering unit coupled to the signal modulation circuit for enciphering the wireless signal prior to modulation thereof, (d) an amplification circuit coupled to the signal modulation circuit for amplification the encrypted and modulated wireless signal, and (e) a signal transmitting circuit having an input coupled to the amplification circuit and an output coupled to a first antenna for transmitting the encrypted and modulated wireless signal to at least one remote wireless signal receiver located within an effective transmission distance from the wireless audio signal transmitter module.
