A speaker comprising a diaphragm (16) which is corn-shaped in the region extending from a bend (21) disposed between the outer and inner peripheries to the outer periphery, and a suspension holder (19) disposed behind the diaphragm, wherein the diaphragm and the suspension holder are joined together at the bend in the diaphragm. This arrangement can eliminate a damper which forms a main factor for the nonlinearity and asymmetry of the suspension, reduce harmonic distortion of the speaker, improve power linearity, and improve the speaker performance. Further, even a planar shape is sufficient to secure rigidity, so that the diaphragm depth for securing diaphragm rigidity is unnecessary, thus making it possible to realize even reductions in size and height. |
