Abstract
A speaker includes a basket; a diaphragm, supported on the basket through a surround; and a voice coil, including a cup-shaped support connected to the basket through a damper. An upper periphery of the cup-shaped support includes protrusion portions in contact with a lower surface of the diaphragm and grooves spaced apart from the diaphragm. The grooves extend in radial directions of the cup-shaped support to form air passages.
