Abstract

PURPOSE:To obtain a speaker that efficiency is good in all bands, by providing two sets of voice coils. CONSTITUTION:Voice coil bubbines 4 and 6 provided with voice coils are arranged in magnetic gaps different in gap width and are connected to diaphragm 9 through the adapter and so on. Since one gap width is made large and the other is made small, magnetic flux density B of the oscillation system of the larger gap width becomes small and electromagnetic damping term Bl<2> (l is the voice coil length) becomes small, the reproducing efficiency of low sound is enhanced without sacrificing the reproducing efficiency of high sound due to the oscillation system of the smaller gap width.
