Abstract

A receiver/transmitter for use in an audio system having a reproducing device for providing reproduced audio signals and located in a home or office. The receiver/transmitter may be operable in a number of modes in which one of such modes enables reproduced audio signals to be transmitted over a broadcast frequency for reception by a wireless receiver tuned to the broadcast frequency and located in a different location of the home or office from that of the receiver/transmitter. Such wireless receiver may be a portable type radio receiver or a stationary type radio receiver. As a result, an operator may listen to a desired portion of a compact disc or tape or the like which is being reproduced by the reproducing device in one room or portion of the home or office while the operator is in a different room or portion of the home or office or while the operator is moving between rooms or portions of the home or office.

Claims

1. An audio system for use in a home or office, said audio system comprising:

means, located in a first location of said home or office, for producing an audio signal; and

means, including means for selecting a desired broadcasting frequency from among a number of broadcast frequencies, for broadcasting said audio signal over the selected broadcasting frequency for reception by a receiving device located in a second location of said home or office.

2. An audio system according to

claim 1

, wherein the receiving device is a portable-type radio receiver.

3. An audio system according to

claim 1

, wherein the number of broadcast frequencies include a number of frequency modulated (FM) frequencies.

4. An audio system for use in a home or office, said audio system comprising:

a reproducing unit, located in a first location of said home or office, for reproducing audio signals from a storage medium; and

a receiver/transmitter unit coupled to said reproducing unit and having means for enabling an operator to select a desired broadcasting frequency from among a number of broadcast frequencies, said receiver/transmitter unit receives the reproduced audio signals from said reproducing unit and broadcasts audio signals corresponding thereto over the selected broadcasting frequency for reception by a second receiver unit located in a second location of said home or office.

5. An audio system according to

claim 4

, wherein said reproducing unit is any of a compact disc player, a cassette tape player, and a phonograph and wherein said storage medium is a corresponding one of a compact disc, a tape, and a record.

6. An audio system according to

claim 4

, wherein said second receiver unit is a portable-type receiver adaptable to be carried by an operator.

7. An audio system according to

claim 4

, wherein the number of broadcast frequencies include frequency modulated (FM) frequencies.

8. An apparatus for use in an audio system located in a first location of a home or office, said audio system having at least one of a compact disc player, a tape player, and a phonograph for providing reproduced audio signals, said apparatus comprising:

means for enabling an operator to select a desired broadcasting frequency from among a number of broadcast frequencies; and

a transmitter circuit for receiving the reproduced audio signals from said compact disc player or said tape player or said phonograph, for processing the received audio signals, and for broadcasting the processed audio signals over the selected broadcasting frequency so as to be received by a remote receiver unit located in a second location of said home or office.

9. An apparatus according to

claim 8

, wherein said transmitter circuit includes a modulator for modulating the received audio signals with the selected broadcasting frequency so as to form modulated audio signals and an amplifier for amplifying the modulated audio signals.

10. An apparatus according to

claim 9

, wherein the number of broadcast frequencies include frequency modulated (FM) frequencies and wherein said modulator is a FM-type modulator.

11. An apparatus according to

claim 10

, wherein said remote receiver unit is a portable-type receiver adaptable to be carried by the operator.

12. An apparatus for use in an audio system having a reproducing device for providing reproduced audio signals and located in a first location of a home or office, said apparatus comprising a transmitter circuit and being operable in a number of modes in which in one of said modes said transmitter circuit receives the reproduced audio signals from said reproducing device, processes the received audio signals, and broadcasts the processed audio signals over a broadcasting frequency so as to be received by a remote receiver unit located in a second location of said home or office.

13. An apparatus according to

claim 12

, wherein said transmitter circuit includes a modulator for modulating the received audio signals with the broadcasting frequency so as to form modulated audio signals and an amplifier for amplifying the modulated audio signals.

14. An apparatus according to

claim 13

, wherein the broadcasting frequency is a frequency modulated (FM) frequency and wherein said modulator is a FM-type modulator.

15. An apparatus according to

claim 14

, wherein said remote receiver unit is a portable-type receiver adaptable to be carried by the operator.
