在现代育儿理念升级与照护需求精细化的背景下，传统婴儿哄睡方式依赖人工安抚，存在效率低、持续性差等问题，尤其对新手父母而言，夜间反复哄睡易导致照护疲劳。婴儿的睡眠质量直接影响其生长发育，稳定的听觉与触觉刺激是辅助入睡的有效手段，因此研发一种自动化、多模式的智能哄睡设备具有重要现实意义。
本设计提出一种基于 STM32F103C8T6 单片机的智能婴儿哄睡系统。系统主要功能包括：通过 MP3 DFPlayer Mini 模块播放舒缓音乐，配备 7 个独立按键实现音乐的启停、上一曲 / 下一曲切换及音量加减调节；借助按键控制步进电机驱动的震动机构，提供 3 个不同强度的震动挡位，适配婴儿对触觉刺激的个性化需求。
该智能婴儿哄睡系统为婴幼儿照护提供了便捷高效的解决方案，通过音乐与震动的协同刺激模拟自然安抚环境，手动按键操作适配照护场景的即时调节需求，有助于提升婴儿入睡效率与睡眠稳定性，减轻照护者负担，具有较强的实用价值。

Design and Implementation of Intelligent Baby Soothing System Based on Single-Chip Microcomputer
Abstract
Against the backdrop of the upgrading of modern parenting concepts and the refinement of care needs, traditional baby soothing methods rely on manual comfort, which has problems such as low efficiency and poor continuity. Especially for new parents, repeated soothing at night is likely to cause care fatigue. The sleep quality of babies directly affects their growth and development, and stable auditory and tactile stimulation are effective means to assist sleep. Therefore, developing an automated and multi-mode intelligent soothing device is of great practical significance.
This design proposes an intelligent baby soothing system based on the STM32F103C8T6 single-chip microcomputer. The main functions of the system include: playing soothing music through the MP3 DFPlayer Mini module, equipped with 7 independent buttons to realize music start/stop, previous track/next track switching and volume adjustment; using buttons to control the vibration mechanism driven by a stepper motor, providing 3 vibration gears with different intensities to adapt to the personalized needs of babies for tactile stimulation.
This intelligent baby soothing system provides a convenient and efficient solution for infant care. It simulates a natural soothing environment through the coordinated stimulation of music and vibration, and the manual button operation adapts to the real-time adjustment needs of the care scenario. It helps to improve the baby’s sleep efficiency and sleep stability, reduces the burden on caregivers, and has strong practical value.
