AUDIO SWITCHING SYSTEM WITH INTERACTIVE PUPPET
First Claim
1. An audio switching system for receiving an electrical signal including an audio signal from at least one audio input, and for providing the audio signal selectively to at least one audio output and to a remote puppet, the switching arrangement comprising:
- (a) a transmitter for transmitting a wireless signal conveying at least the content of the audio signal;
(b) a puppet including;
(i) a receiver for receiving said wireless signal, (ii) an amplifier for amplifying audio content derived from said wireless signal, and (iii) a speaker for outputting said audio content;
(c) an electronic switch electrically switchable between a straight-through state wherein the audio signal from the audio input is transferred to the audio output and a diverted state wherein the audio signal from the audio input is transferred to said transmitter for transmitting to said puppet; and
(d) a signal processor associated with the at least one audio input and configured to be responsive to a predefined actuation signal superimposed on the audio signal as part of the electrical signal from the audio input to switch said electronic switch from said straight-through state to said diverted state.

Abstract
An audio switching system alternately directs an input audio signal to an audio output and to a remote puppet. The system includes an audio switching arrangement with a transmitter and a puppet including a receiver, an amplifier and a speaker. The audio switching arrangement includes an electronic switch electrically switchable between a straight-through state wherein the audio signal from the audio input is transferred to the audio output and a diverted state wherein the audio signal from the audio input is transferred to the transmitter for transmitting to the puppet. A signal processor, associated with the audio input, responds to a predefined actuation signal superimposed on the audio signal as part of the electrical signal from the audio input to switch the electronic switch from the straight-through state to the diverted state. The frequency and/or duration of the actuation signal is preferably chosen to render the actuation signal substantially non-intrusive to the hearing of the user.

17. A method for providing audio signals selectively to an audio output and to a remote puppet, the method comprising:
-
(a) monitoring at least one electrical signal received from an audio input for a predefined actuation signal superimposed on the audio signals;
(b) in the absence of the predefined actuation signal, outputting an audio signal from the electrical signal to the audio output; and
(c) on detection of the predefined actuation signal, diverting the audio signal from the electrical signal to a transmitter for transmission to the remote puppet. - View Dependent Claims (18, 19)
