Active Equalization for Loudspeaker Protection

Document Thumbnail

We present a time-varying linear equalization algorithm whose purpose is to protect a loudspeaker from damage under high drive conditions. It is suitable for implementation on a low-cost digital signal processor, often integrated on the same die as a high-performance audio codec. A typical application is in a portable wireless (e.g., Bluetooth) loudspeaker. For a given driver and enclosure design, the algorithm allows the power output of the loudspeaker to be maximized while introducing only minimal coloration or distortion. During the loudspeaker design phase, the parameters of the algorithm can be easily tuned by the designer, further optimizing the overall design for power output, robustness and low distortion.
