Abstract

PURPOSE:To avoid the split oscillation of diaphragm, by making equal the area of outside and inside sectioned with the fitting position of the voice coil bobbin. CONSTITUTION:The hole 12 is made at the center of the square diaphragm 11. The square voice coil bobbin 13 is fitted to the diaphragm 11. The area for external circumference S1 and the area for inner circumference S2 which are sectioned with the bobbin 13 are made equal. Thus, partially easily oscillatary parts and partially difficultly oscillatory parts are eliminated from the diaphragm, and split oscillation is suppressed.
