Latest Patents

Among his latest patents is an audio speaker protection system and method. This innovative audio device includes an audio amplifier that is configured to receive an input signal and generate a differential output signal. A first signal combiner circuit is designed to create a time-convolution signal of an analog current signal and an analog voltage signal. The analog current signal corresponds to the current at the differential output signal, while the analog voltage signal corresponds to the voltage across the differential output signal. Additionally, a second signal combiner circuit is configured to subtract the generated time-convolution signal from the input signal. Another patent focuses on a circuit that includes an audio amplifier, which amplifies an input signal to generate an output signal suitable for driving a loudspeaker. This circuit generates first and second analog signals based on the current level drawn by the loudspeaker and the voltage supplied across it, respectively. A third circuit generates a third analog signal based on the difference between the first and second analog signals, modifying the input signal accordingly.
