4-Microphone Linear Array for Far-Field Voice Capture
The GYKS-4M-Q360-LP adopts a linear 4-MEMS microphone array architecture, with microphones arranged at equal intervals to improve spatial audio acquisition capability.
Compared with traditional single microphone solutions, the 4-microphone array provides stronger directional voice pickup performance through intelligent signal processing algorithms, effectively improving speech clarity and reducing environmental noise.
The module supports USB digital audio output, allowing direct connection with embedded systems, PCs, AI terminals, smart displays, conference devices, and voice-controlled equipment.
Key Features
High-Performance Far-Field Voice Pickup
- 4-channel MEMS microphone linear array design
- Pickup distance up to 6–10 meters
- High sensitivity: -30 dB FS
- High signal-to-noise ratio: 64 dB(A)
- Maximum acoustic overload point: 120 dB SPL
The module provides stable voice acquisition performance in open environments, suitable for long-distance human-machine interaction.
Advanced Audio Algorithms
The integrated audio processing algorithms improve speech intelligibility and user experience:
Acoustic Echo Cancellation (AEC)
Removes speaker feedback and echo interference in voice communication scenarios, improving full-duplex conversation quality.
Beamforming (BF)
Uses multi-microphone spatial processing technology to enhance sound from the target direction while reducing unwanted sounds from other directions.
Noise Suppression (NS)
Suppresses background noise including:
- Environmental noise
- Fan noise
- Machine noise
- Office background noise
Automatic Gain Control (AGC)
Automatically adjusts microphone gain according to voice intensity and distance, maintaining consistent audio output levels.
Hardware Features
- 4-MEMS linear microphone array structure
- USB Audio Class 1.0 (UAC 1.0) supported
- USB Control interface for debugging and parameter configuration
- Supports USB HUB connection with camera devices
- Compact linear microphone PCB design
- Plug-and-play USB audio solution
