Key Selling Points (Education Focused)
Precision Dual-60° Pickup: Focuses exclusively on the speaker directly in front of the device. This “narrow-angle” capture prevents the microphone from picking up side chatter or room reflections.
Side-Speaker Suppression Technology: Designed for devices where microphones and speakers are in close proximity. The array’s polar pattern naturally creates “null points” at the sides, effectively muting feedback from lateral speakers.
AI-Powered Acoustic Suite:
AEC (Acoustic Echo Cancellation): Optimized for high-volume classroom environments to prevent “echo loops” during active dialogue.
NS (Noise Suppression): Filters out typical home/classroom noises like page-turning, air conditioning, and distant background voices.
AGC (Auto Gain Control): Ensures a consistent volume level even if the student moves slightly away from the screen.
Plug-and-Play UAC 1.0: Instantly compatible with Windows (Zoom/Teams), Android (Educational Apps), and Linux-based learning terminals.

Application Scenarios in Education
Smart Student Tablets: Prevents the microphone from picking up its own side-firing speakers during interactive lessons.
Teaching All-in-One Machines: Allows teachers to be heard clearly while suppressing the noise of students sitting to the sides.
AI Language Tutors: Provides the high-fidelity, focused audio required for accurate pronunciation analysis and STT (Speech-to-Text).
Desktop Study Lamps with Voice Control: Narrow 60° pickup ensures only the person at the desk can trigger voice commands.
Why This Solution?
Compared to standard 360° omnidirectional 2-mic arrays, the GYKH-2M-FB60-U acts like a “Virtual Shield.” While standard mics struggle with speaker feedback in compact devices, our Dual-Directional 60° technology creates a “dead zone” for the side speakers, allowing for higher volume levels and clearer communication without howling.
