Abstract
A magnetic resonance imaging (MRI) acoustic system includes a magnet; an electro-acoustic transducer that includes a coil through which a current flows so that an attractive force or a repulsive force is generated with respect to the magnet, and a vibrating plate that vibrates in response to the attractive force or the repulsive force; and a controller that controls an intensity of a current input to the electro-acoustic transducer according to a position of the electro-acoustic transducer in a magnetic field generated by the magnet.
