The speaker driver has its surrounding cover removed

Abstract

The invention relates to a loudspeaker in which the enclosure (suspension) is removed, comprising a magnet set in a set form, a vibrating device set adjacent to the magnet and producing sound by oscillation, and a thick coil set between the magnet and the vibrating device in the form of a coil, producing magnetism in either the first or second direction opposite to the first when power is supplied to the coil, and vibrating the vibrating device by action. When applied to the vibrating part, a force is generated along with the magnetism of the magnetic component.
