Abstract

PURPOSE:To increase magnetic flux density and to improve the space factor of a voice coil by connecting the voice coil and a diaphragm via an edge. CONSTITUTION:To the edge 1, the voice coil 2 is connected, and is mounted, by using a voice coil jig 3, on a magnetic circuit constituted of a plate 4, a magnet 5, and a plate with pole. Thereafter, the jig 3 is pulled upward, and the voice coil 2 and the diaphragm are bonded together. In such a way, the position of the voice coil can be exactly determined by means of the jig 3, hence a necessary magnetic gap 9 can be most shortened. As a result, the magnetic flux density as well as the space factor of the voice coil can be enhanced.
