摘要: 反重力智能悬浮音箱,主控核心设计基于STC89C52单片机,外电路主要包括磁悬浮控制电路和无线充电电路。核心的模块是磁悬浮控制电路,基于Keil软件和C语言完成程序编程,利用PWM技术驱动全桥电路和PID控制算法控制电流,使音箱悬浮在空中并处在动态的平衡中。Abstract: The anti-gravity intelligent levitation speaker, the main control core design is based on the STC89C52 single-chip microcomputer, and the external circuit mainly includes a magnetic levitation control circuit and a wireless charging circuit. The core module is the magnetic levitation control circuit, which is based on Keil software and C language to complete program programming, uses PWM technology to drive the full bridge circuit and PID control algorithm to control the current. The speaker is suspen and in dynamic balance.
