Smart Toy PCBA Solution Development

I. Overview of the Plan

Siring offers one-stop PCBA solutions for consumer electronics sectors—including smart toys, companion robots, and educational hardware—spanning product definition, hardware design, embedded software development, PCBA prototyping, and mass production. Centered on a highly integrated main control board, these solutions integrate voice interaction, emotional display, motion control, and multi-sensor coordination capabilities, enabling customers to rapidly bring smart toy products from concept to market.

II. Core Features

1. Voice Interaction

Dual MENS microphone array pickup, featuring far-field noise cancellation and echo cancellation.

Dual-mode: offline wake-up + online ASR/TTS

Support for customizable wake-up phrases, dialogue flows, and emotional speech recognition for children.

2. Motor Control

Powered by dual miniature reduction motors, it supports differential steering, obstacle avoidance, and posture stabilization.

6-axis motion sensor (3-axis accelerometer + 3-axis gyroscope) for real-time posture detection

Supports multiple motion modes, including music rhythm, interactive following, and automatic cruise control.

3. Transmission and Feedback Integration

ToF sensor enables proximity wake-up and distance detection for human presence detection.

The touch buttons support multi-point touch control interaction on the crown and abdomen.

Multi-sensor fusion enables fall detection, grip sensing, and environmental perception.

4. Emotional Expression

Colorful expression display screen (driven by the main MCU), supporting a wide range of animated expressions and ambient lighting-based emotional feedback

LED light ring / programmable lighting effects, enabling emotional resonance when paired with voice content.
