Japanese Patent JP5392841
Kind Code:

Abstract:
A speaker device has a magnet, outer yokes, and inner yokes which are assembled so that a magnetic gap is formed between the outer yoke and inner yokes over which a magnetic flux which is generated from the magnet cuts across. A voice coil unit which is linked to a diaphragm is disposed within the magnetic gap, and positioning members determine the positions of the inner yokes and the outer yokes which attach magnetically to the magnet such that a magnetic gap is formed. The speaker device has a magnetic circuit of which the construction facilitates assembly, and recycling of various individual parts is relatively easy.
