    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.
