Abstract

A speaker device in which a diaphragm and a voice coil are joined to each other at high accuracy and relatively high joint strength and that provides reproduced sound of relatively high sound quality. These are achieved even when the diaphragm is fixed to the upper end of the voice coil and a leader line led out of the inner periphery of the voice coil is led out through the upper end of the voice coil. The speaker device (1) has the ringlike voice coil (33) and the diaphragm (31) joined to one upper end of the voice coil (33). In the diaphragm (31), a cutout (31C) is formed at a position corresponding to the position through which the leader line (4) led out of the inner periphery of the voice coil (33) is led out. The leader line (4) led out of the inner periphery of the voice coil (33) is led out to the outside of the voice coil (33) through the one upper end of the voice coil (33) and through the cutout (31C). The voice coil (33) is joined to the diaphragm (31) so that a part of the entire circumference of the upper end of the voice coil covers the cutout (31C) of the diaphragm (31).
