Pre-filtering for loudspeakers protection |
摘要 |
The present invention relates to a method of protecting an inductive loudspeaker. The method comprises filtering the audio stream by applying a compensation filter to the audio stream, sending the filtered audio stream to the inductive loudspeaker, computing an estimation of a frequency response of the inductive loudspeaker and updating the compensation filter so as to attenuate a frequency corresponding to a resonant frequency in the estimated frequency response of the inductive loudspeaker. |
