摘要

A subcone is configured from a center dome and an outer dome provided on the outer circumference of the center dome. A voice coil bobbin is bonded at the boundary between the center dome and the outer dome, and a diaphragm is bonded on the outer circumference of the outer dome. Thereby, breakage and deformation is suppressed because the outer circumference of the subcone is not in a free state but is bonded and fixed to a diaphragm.
