Wireless USB Microphone Solution

This solution consists of one transmitter module and one USB microphone receiver module. The transmitter module can connect to a microphone and audio signals, while the receiver module communicates with computers or tablets and other mobile devices through audio data streaming, enhancing signal-to-noise ratio and lossless transmission. This solution is applicable in scenarios such as online karaoke, computer recording for musical instruments, teaching and speech amplification, recording, speech recognition, and speech-to-text conversion.
