Physical Specifications

Slim & Energy-Efficient Design:

• Main Board: 100 * 20 mm (Standardized DSP and USB UAC 1.0 interface).

• Microphone Board: 45 * 6 mm (Ultra-small 2-mic footprint, ideal for minimalist hardware designs).

Key Technical Highlights

• 60° Directional Precision (DPUS): The core advantage of this 2-mic array. It creates a focused “pickup cone” to eliminate side-chatter and ambient background noise.

• Low-Power Architecture: Optimized for energy-sensitive applications, extending battery life in portable or always-on devices.

• Essential Acoustic Suite:

  • AEC (Acoustic Echo Cancellation): Reliable echo suppression for clean voice calls.

  • NS & VE (Noise Suppression & Voice Enhancement): Effectively removes steady background noise while boosting human speech clarity.

  • BF (Beamforming): Precise 2-mic digital beamforming for directional accuracy.

  • AGC (Auto Gain Control): Ensures a consistent output level for voices within a 1-3 meter range.

• Plug & Play UAC 1.0: Driverless USB connectivity for seamless integration with all major operating systems.

Application Scenarios

• Smart Consumer Electronics: Smart home controllers, voice-activated appliances, and entry-level smart speakers.

• Personal Office: Budget-friendly webcams, desktop microphones, and laptop acoustic upgrades.

• Mass Retail & Public Space: Intelligent vending machines, basic informational kiosks, and price checkers.

• Wearables & IoT: Portable AI translators and voice-controlled smart toys.
