Abstract

PURPOSE:To adjust the magnetic flux density of a magnetic gap over a range by increasing the safety current of an energizing coil by arranging energizing coils around a pole despersedly and by making those coils detachably. CONSTITUTION:Energizing coils 8 are arranged around a pole despersedly and the magnetic core 9 of each coil is fixed tightly to a yoke 3 and a plate 4 with fixing screws 10. Thus, respective coils 8 are arranged dispersely to improve radiation while increasing each safety current. Further, each coil 8 is detachable with the screws. Therefore, the magnetic-flux density of a magnetic gap 7 is adjusted over a wide range according to the current value of each coil 8, a connecting method and the number of used coils, so that the optional performance of a speaker is obtained.
