Transducer Protection Circuits TRIZ Cases
- Speaker Current Detection Circuit for Clipping-Safe Class-D Protection
Current mirror sensing and PDM conversion track speaker current during high-power clipping without adding series loss to Class-D output.
- Vehicle Loudspeaker Low-Frequency Equalization Against Distortion
Calibration and dynamic equalization extend vehicle loudspeaker bass response while limiting distortion and unwanted vibrations.
- Curved Piezoelectric Speaker Structure for Thin Stable Sound Output
A layered curved piezoelectric sheet with a reinforcing film keeps thin speakers stable while improving wide-band frequency response.
- Speaker Enclosure Status Detection for Adaptive Excursion Control
Impedance-based enclosure status detection lets portable speakers switch excursion models to protect the transducer and preserve sound quality.
