Abstract
PURPOSE:To attain smooth vibration of a vibration system by providing a throughhole whose outer diameter is specified to the center of a flat diaphragm. CONSTITUTION:The outer diameter D of the throughhole 10a provided to a flat diaphragm 10 is larger than the outer diameter d1 of the 1st bobbin 5, and smaller than the outer diameter d2 of the 1st sub cone 7. Thus, a 1st space A of a 1st magnetic circuit 1 and a 2nd space B of a 2nd magnetic circuit 11 are communicated and when the 1st space A is expanded, the 2nd space B is compressed and since the 2nd space B is expanded with the 1st space A compressed, the total volume of the 1st space A and the 2nd space B is always constant. Thus, the air in the 1st space A and the 2nd space B is not compressed and expanded, then the vibration of the vibration system is not suppressed but smoothed.
