ABSTRACT:
A speaker has a diaphragm (16) and a suspension holder (19) supporting the diaphragm from the back surface of the diaphragm. The diaphragm has a bent section (21) disposed between its outer periphery and its inner periphery, with the portion to the outer periphery having a conical shape. The diaphragm is coupled to the suspension holder at the bent section. This configuration can omit a damper that causes nonlinearity and asymmetry of suspension, to reduce the harmonic distortion of the speaker and improve the power linearity and the performance of the speaker. The diaphragm can have a flat configuration at its inner peripheral portion, can be secured with sufficient rigidity, and can be rigidly secured to a frame of the sneaker. This can reduce the thickness of the diaphragm and enable formation of a smaller, low profile sneaker can be realized.
