Abstract

PURPOSE: To enlarge a degree of freedom of a design of a tone quality at the time of a design, by integrating a diaphragm whose surface density has been varied stepwise in the diameter direction, into a frame which has been coupled to a field part, and coupling a voice coil fitted into a magnetic gap of the field part, to the diaphragm.
CONSTITUTION: A frame 8 is coupled to a field part 3, and to the peripheral edge part of the frame 8, the peripheral part of a diaphragm 10 is coupled by an adhesive agent together with a gasket 9. The diaphragm 10 is constituted so that the surface density is varied stepwise in the diameter direction. To the center part of the diaphragm 10, a voice coil 11 is coupled, the middle part of the coil 11 is held by a damper 12, and the lower part of the coil 11 is fitted into a magnetic gap 13 of the field part 3 without eccentricity. In this way, a degree of freedom of a design of a tone quality at the time of a design is enlarged.
