Integrated 8-Mic 180° Frontal Directional MEMS Microphone Array Module with AEC & Beamforming-GYKH-8M-F180-U

Product Overview

The GYKH-8M-F180-U is a high-density 8-microphone MEMS array specifically engineered for scenarios requiring precise frontal pickup and rear-noise suppression. By combining 8 high-SNR MEMS sensors with adaptive beamforming and differential directional algorithms, this module creates a stable 180° fan-shaped pickup zone.

It is the ideal acoustic solution for Smart TVs, Soundbars, and Automotive infotainment systems, where it effectively isolates user speech from rear interference, speaker echoes, and room reverberation, ensuring superior clarity for both human communication and AI voice recognition (ASR).

 Key Technical Highlights

  • High-Density 8-Mic Matrix: Compared to standard 4-mic solutions, the 8-mic architecture delivers a narrower beam and stronger directivity, ensuring crystal-clear voice pickup within a 5-meter range.

  • 180° Frontal Directionality: Optimized for users positioned in front of the device. It effectively mutes sound from the rear and sides, preventing false triggers and background noise interference.

  • Pro-Grade Acoustic Processing:

    • AEC (Acoustic Echo Cancellation): Essential for full-duplex communication in TVs and Soundbars.

    • NS (Noise Suppression): Advanced suppression of ambient noise and room reflections.

    • Beamforming (BF): Digitally focuses on the active speaker for enhanced signal quality.

  • Seamless System Integration: Supports standard digital interfaces (USB / I²S) and is fully compatible with mainstream voice platforms like XMOS, Android, and Windows.
