摘要： A speaker apparatus capable of operating in a large amplitude regime by minimizing magnetic loss, is provided. The speaker device includes a magnet configured to generate a magnetic flux, a pole piece configured to form a path of the magnetic flux generated by the magnet, a back plate provided at a lower end of the pole piece to support the magnet, and a plate provided to form a magnetic gap between the plate and the pole piece. Several plates may be provided so that the magnetic gap is expanded to enlarge amplitude of output sound.
