This abstract first appeared for US patent application 20240406624 titled 'LOUDSPEAKER EXCURSION PREDICTION SYSTEM
Original Abstract Submitted
a loudspeaker excursion prediction system, which is suitable for a loudspeaker protection circuit comprises a low-pass filter circuit, a down-sampling circuit, and an impulse response generation unit. the low-pass filter circuit is configured to generate an audio signal x(t) passing through the low-pass filter circuit according to an audio signal x(t) with a first sampling frequency. a down-sampling circuit, coupled to the low-pass filter circuit, is configured to down-sampling the first sampling frequency of the audio signal x(t) output from the low-pass filter circuit to a second sampling frequency, so as to generate a down-sampled audio signal x(t). the impulse response generation unit, coupled to the down-sampling circuit, is configured to generate an excursion prediction value according to a loudspeaker excursion transfer function and the down-sampled audio signal x(t).
