High-performance microphone unit for smartphones and headsets.
Compared to our conventional products, we have maintained low THD (total harmonic distortion) characteristics, improved high SNR (signal-to-noise ratio), and enhanced sound pickup performance in the low-frequency range. The flattening of the low-frequency characteristics allows for effective sound pickup in the bass range as well as noise cancellation in the low-frequency band. Both SNR and THD are at the industry's highest level, and we also offer a low power consumption switching mode, contributing to energy savings for the product. *For more details, please refer to the PDF document or feel free to contact us.*
