ARM301

1. Product Overview

ARM301 is an ultra-thin magnetic module for business meetings, customer visits, interviews and research, classroom learning and inspiration records. The fuselage is only 45 × 11 × 4mm, which can be easily adsorbed on the edge of clothes, pockets or bags, and can be recorded at any time. The equipment is equipped with a dual-silicon microphone array, which supports local recording storage, Bluetooth real-time audio transmission and WiFi dual-frequency fast transmission. Through Bluetooth and App linkage, voice transcription, real-time transcription, translation, multi-person role distinction and intelligent summary are realized in combination with a large model, communication points and meeting decisions are automatically precipitated, and users are helped to complete a complete closed loop from voice recording to information sorting and action follow-up.
