Abstract

PURPOSE:To attain the reproduction of ultralow sound with high equality even with a speaker having small diameter by providing >= 2 magnetic on, one dia phragm to powerfully control the diaphragm while driving said diaphragm. CONSTITUTION:The magnetic circuit consists of a 1st magnetic circuit compris ing a 1st pole piece 13, a 1st yoke plate 14 and a 1st magnet 15 and of a 2nd magnetic circuit comprising a 2nd pole piece 23, a 2nd yoke plate 24 and a 2nd magnet. A coupling rod-shaped member 21 is provided in voice coils 12, 22 of the 1st and 2nd magnetic circuits and the coupling rod-shaped member 21 is fixed to the voice coils 12, 22 via a connection ring member 28. A dia phragm 11 is fixed to the voice coil 12.
