An electromagnetic vibration device includes a vibrating plate, a suspending frame, upper and lower basin frames, a voice coil, and a magnetic loop system. Multiple voice coil fixing slots are uniformly distributed on the circumference of the vibrating plate corresponding to the inserting pieces of the voice coil, and the inserting pieces are passed through the voice coil fixing slots of the vibrating plate and fixed to the vibrating plate. One end of the lead of the voice coil is embedded in a groove on back of the vibrating plate and connected to the terminal of the lower basin frame.
