SmartSound Ultrasonic Voice Prompter is a product of WeiChuang Electronic Co., Ltd., which adopts advanced ultrasonic ranging technology to realize object-to-probe distance detection. The detection accuracy reaches the centimeter level. The product not only can real-time voice prompt the detected distance status, but also set a threshold value freely. When the threshold value is reached, it can sound and light alarm to timely remind customers and avoid various losses caused by distance misjudgment.
The SmartSound ultrasonic voice reminder uses ultrasonic distance detection to provide real‑time voice prompts and optional sound‑light alarms when an object is within a preset range. It operates from a 5 V DC supply, supports MP3 audio files, and includes a built‑in 2 W/8 Ω speaker. The device is designed for plug‑and‑play use in retail, security, and safety applications.
The manual details hardware installation (connecting power, USB, TF‑card, and speaker), configuration steps (loading MP3 files via USB, learning distance thresholds, and trigger operation), and typical use cases such as advertising displays, key‑less doorbells, and safety line reminders. A FAQ section addresses audio format support and voice file updates. This manual is written in Chinese.
