Product Description:
USB 2.0 interface;
Dual microphones;
AI noise reduction, voice enhancement;
Applicable to voice calls, human-computer interaction, voice recognition,
smart terminal devices, Android devices and other scenarios;
The noise reduction microphone board has a built-in AI noise reduction algorithm, including noise suppression and automatic gain functions, which can achieve omnidirectional sound pickup and suppress noise other than human voice. It also supports extended microphone cable and USB interface, plug and play, which is very suitable for the sound pickup function requirements of devices such as voice recognition, human-computer interaction, and voice calls.
Dual Directional Microphone Modules
As a specialized audio hardware manufacturer, we possess full in-house R&D and production capabilities for advanced microphone array modules like the HK-SDXMIC-V1.1. Our factory is equipped with dedicated acoustic laboratories, automated SMT assembly lines, and precision audio calibration systems that enable end-to-end control over every stage of production—from PCB design and DSP algorithm tuning to final acoustic testing and quality assurance. We have successfully delivered dual-channel directional microphone solutions for government, financial, and law enforcement clients worldwide, demonstrating proven expertise in speaker separation, beamforming optimization, and embedded USB audio module manufacturing. All products undergo rigorous environmental and performance validation to meet industrial-grade reliability standards, ensuring consistent audio quality at scale. Whether you require standard specifications or custom OEM/ODM adaptations, our engineering team can rapidly prototype and mass-produce microphone modules tailored to your exact application requirements.
