Abstract:
A load detector for an audio system comprising a closed-loop amplifier is described. The load detector includes a noise detector configured to be coupled to the output of the closed-loop amplifier. The noise detector detects a noise signal at least partially generated by the amplifier. The generated noise signal comprises frequencies outside the audible frequency range due to the noise shaping of the amplifier. The load detector further includes a parameter calculation module having an input coupled to the output of the noise detector and an output. The parameter calculation module is configured to determine a parameter value relating to an impedance of the amplifier output load from the detected noise signal and to output a load detection signal dependent on the determined parameter value. The load detector may detect the presence of a load such as a tweeter without generating a reference signal.

Claim (Index 20):
The method of  claim 11 , wherein generating the load detection signal is determined in response to at least one of no load being detected and no tweeter being detected.
