Abstract:
A loudspeaker driver circuit, comprises: at least one input for receiving an input signal; a loudspeaker protection module coupled to the input for receiving the input signal and for generating a modified signal in response to the input signal; an amplifier coupled to receive the modified signal from the loudspeaker protection module and to generate an output signal; an output for outputting the output signal for driving a speaker; and an ultrasonic signal generator, for generating an ultrasonic signal, wherein the ultrasonic signal generator is coupled to the amplifier for applying the ultrasonic signal thereto.

Claim (Index 18):
An audio processor circuit, comprising:\n a source of an audio signal; at least one output for connection to a loudspeaker driver circuit; an input for receiving a signal representing an echo of an ultrasonic signal generated in response to an output of the loudspeaker driver circuit; and an ultrasonic information generator, for generating ultrasonic information that can be used by an ultrasonic processing module for generating an ultrasonic signal in response thereto, wherein the ultrasonic information generator is configured for generating said ultrasonic information based on the received signal representing the echo of the ultrasonic signal, and wherein the audio signal and the ultrasonic information are applied to the at least one output.
