WHEELTEC M260C Smart Speaker Microphone Array with 10m Pickup Distance & Exquisite Industrial Design

WHEELTEC M260C Smart Speaker Microphone Array with 10m Pickup Distance & Exquisite Industrial Design

Product Introduction:
The microphone array enables sound source localization and semantic analysis. And when combined with a speaker, it can perform voice broadcasting. It supports secondary development. We provide detailed development tutorials and example applications such as TTS (text-to-speech), directional recording, and voice-controlled robots. Additionally, it supports integration with iFlytek's voice cloud services, enabling powerful features such as pronunciation correction and voiceprint recognition. It can be applied in various fields including voice-controlled smart homes, meeting recordings, real-time translation, robotic interaction, accent correction, and intelligent cockpits for vehicles.

Features:
Highly Integrated Product Design with Exquisite Industrial Aesthetics
* The M260C Smart Speaker features a refined industrial design and a high-quality metal casing as standard. It integrates a built-in M260 circular 6-microphone array, a noise reduction motherboard, a signal adapter board, and a speaker with sound card. It offers high integration for quick and easy use. It supports voice wake-up and intelligent interaction.

Supports Sound Source Localization and Directional Output
* Utilizing the TDOA (Time Difference Of Arrival) algorithm, the system achieves sound source localization. The circular microphone array enables 360-degree localization of sound sources.

Supports Directional Recording
* By activating the system from a specific angle, it can focus on recording audio from that particular direction.

Compatible with DeepSeek Large Models for Combined Applications
* The microphone array delivers a clear voice interaction experience and supports the universal UAC protocol. It can seamlessly integrate with large models such as DeepSeek to enable efficient voice input and intelligent responses.

Supports Offline Speech Recognition
* Powered by an offline recognition engine, it enables real-time responses with zero data usage, providing fast and stable local voice services.

Supports Voice Wake-up
* Users can set custom wake words, which will activate the circular microphone array for use upon detection.

Supports Audio Noise Reduction
* It can output either raw or noise-reduced audio files.
* Raw audio format: 16kHz, 16-bit, 8-channel PCM audio (8 channels = 6 microphones + 2 speaker reference signal inputs)
* Noise-reduced audio format: 16kHz, 16-bit, single-channel PCM audio

10m Pickup Range
* Long-distance pickup: It collects distant sounds more clearly, ensuring accurate pickup of low, mid, and high-frequency audio.
* Short-distance pickup: It accurately collects sounds from specific directions while effectively reducing ambient noise interference.

Supports Echo Cancellation
* Through a reference signal interface, it can detect and process echoes, enabling echo cancellation functionality.

Universal UAC Protocol Audio
* The output audio complies with the universal UAC (USB Audio Class) protocol, allowing direct audio collection by computers without the need for dedicated drivers.

Supports Serial Communication Control
* Users can control functions via serial communication, such as starting recordings, retrieving wake-up status, setting wake words, and acquiring the wake-up direction angle.

Supports TTS Audio Conversion
* TTS functionality allows text to be converted into corresponding audio files, making it easier to implement various interactive features.

Enables Voice Control and Navigation for Robots
* This device can be integrated with robots to enable voice control and voice navigation. It is compatible with ROS and can work in coordination with robotic systems to achieve intelligent voice-based functions.

Ready-to-Use Pre-configured Development Environment
* The system is for Linux and Android, with a primary focus on Linux application development. For users who need to develop with the system but lack a Linux environment, we provide a pre-configured Windows virtual machine image—ready to use upon installation.

Compatible with Various ROS Controllers
* The included documentation features standard ROS function packages, allowing integration with different main controllers (e.g., Jetson Orin Nano board) to meet microphone array usage needs in ROS environments.

Supports Use in ROS2 Environments
* It supports voice interaction and other functionalities in ROS2 environments. We also provide a series of ROS2 voice-focused video tutorials and documentation.

Built-in Signal Adapter Board
* The integrated signal adapter board processes the microphone array signals and allows for easy connection to a computer via a single type-c data cable. It significantly streamlines the development process.

Application Scenarios
* Voice-controlled smart home systems
* Meeting recording
* DeepSeek large model integration
* Robot interaction
* Intelligent vehicle cockpits
* Accent correction
* ROS-based robot development
* Sound source localization
* Environmental noise reduction
