Abstract

A sound card of a personal computer provides an audio signal that modulates a carrier of an FM transmitter. Radiation from the transmitter is received by an FM receiver.

Claims

1. An apparatus for reproducing sound, comprising:

a personal computer that includes a sound card installed therein; and

transmitter means coupled to said sound card for radiating a carrier signal that is modulated by an audio signal provided by said sound card, said carrier signal being received by a home entertainment system receiver for the high fidelity reproduction of said audio signal from said personal computer, said sound card including a midi port that has only a single, direct connection to said transmitter means, said single, direct connection from said midi port providing a maximum of 5 VDC power to said transmitter means.

2. The apparatus of claim 1 wherein said carrier signal is frequency modulated.

3. In the method of providing a wireless link between a sound card of a personal computer and a high fidelity home entertainment system receiver, the steps of:

modulating a carrier signal provided by a transmitter with an audio signal provided by said sound card;

radiating said modulated carrier signal;

receiving said modulated carrier signal and reproducing said personal computer'"'"'s sound with said hi fidelity home entertainment system receiver; and

providing a maximum of 5 VDC power to said transmitter from a single, direct connection from a midi port of said sound card.

4. In the method of claim 3 wherein said step of modulating includes frequency modulating.

5. In the method of claim 3 wherein said radiating is at a frequency in a range of 88 megahertz to 108 megahertz.
