Product Overview
Clear direction information for audio interaction
The module includes a five-channel circular microphone array algorithm for voice enhancement, sound source localization, acoustic echo cancellation, noise suppression, and automatic gain control.
- Far-field and 360° omnidirectional pickup
- Sound source coordinates via serial TTL output
- LED indication of source direction
- Speaker output and AEC interface support
360° Sound Source Localization
360° sound source localization with LED direction indication
The module localizes sound sources in all directions and outputs the coordinates of a human voice. On-board LEDs show the source direction for human-machine interaction and AI devices that need immediate directional feedback.
Typical uses: intelligent robots, conferencing terminals, voice interaction equipment, smart displays, and IoT devices.
Audio Processing
Suppress environmental noise while preserving clear speech
Acoustic echo cancellation, voice enhancement, and noise suppression algorithms reduce the impact of air conditioners, fans, and other environmental noise on calls and voice interaction for clearer, smoother output.
- Acoustic echo cancellation (AEC)
- Voice enhancement
- Noise suppression (NS)
- Automatic gain control (AGC)
Hardware Capabilities
Amplifier and speaker output support
The module supports dual 3 W amplifier chips and can connect directly to speakers for voice interaction. On-board audio output, AEC, and speaker interfaces simplify system integration.
Refer to the specification table and the final order confirmation for interface and electrical details.
Applications
Designed for a range of intelligent voice applications
For robots, AI terminals, IoT devices, large-screen systems, advertising machines, and other products that require audio pickup, voice interaction, or sound source localization.
