A Loudspeaker with Dual Coils and Dual Magnetics
By using dual coils and dual magnetic gaps in the drive system of a loudspeaker, the electromagnetic force can be made constant even with large displacement from the resting state. Dual-drive techniques were used in 1950 in order to increase the total power but not to improve linearity. This older technique can be used to lower distortion. In order to confirm the results of the mathematical simulation, specially constructed loudspeakers were tested. Distortion was significantly reduced. The advantages of this approach need to be balanced against higher manufacturing cost.
