Transducer Circuit Damping TRIZ Cases
- Loudspeaker Reference Resistance Calibration for Thermal Protection
Measured loudspeaker voltage and current establish a true reference resistance, enabling recalibration and tighter thermal protection.
- Sealed Speaker Equalization With Variable Sub-Resonance Cutoff
Feedback-controlled DSP equalization boosts sealed-speaker bass below resonance while shifting cutoff to avoid over-excursion and distortion.
