摘要： A balanced vibration system including a magnetic circuit unit, a vibration unit and a casing. The magnetic circuit unit and the vibration unit are inside the casing. The vibration unit includes a balanced iron core and a vibrating diaphragm; the balanced iron core is movably connected with the casing, the vibrating diaphragm is fixed on the casing, and the balanced iron core drives the vibrating diaphragm; the magnetic circuit unit includes a magnetic circuit coil and magnet groups, the magnetic circuit coil is sleeved on the balanced iron core, and the two magnet groups are respectively located at ends of the balanced iron core along an axial direction; each magnet group includes magnets which are arranged oppositely at both sides of the balanced iron core; when the magnetic circuit coil is ON, magnetic field forces applied by the two magnet groups to the balanced iron core are same in direction.
