Abstract
PURPOSE:To obtain a speaker of a reduced depth size without impairing acoustic effect by interposing voice coils between permanent magnets and disposing both in the same plane position. CONSTITUTION:For example, three pieces of voice coil parts 11 are of approximately plate form and one side thereof is bonded to the approximate central part of a cone part 12. The outside circumferential end part of the cone is supported to a frame 13 through edge 14. Four permanent magnets 15 are disposed so as to sandwich the coil parts and the respective magnetic poles of the four magnets 15 are constituted in series, the magnets at the end parts being coupled by a yoke 16 thereby forming a closed magnetic path. All the magnets are fixed and positioned to the yoke by means of a non-magnetic member 17. In this way, the voice coils and permanent magnets may be disposed on the same plane and the depth sizes of the two speakers may be reduced.
