Abstract

PURPOSE:To improve the driving force of a diaphragm and magnetic non- linerarity by providing two magnetic circuits to one diaphragm. CONSTITUTION:The titled device is equipped with a first-a third voice coils 13-15 wound at intervals on the peripheral face of a cylindrical voice coil bobbin 12 whose one end is fixed to the central part of a diaphragm 11, a first-a third yoke plates 18, 19 and 21 placed having slight clearances to the respective peripheral faces of these voice coils 13-15, a first magnetic circuit composed of a first magnet placed between the first yoke plate 18 and the second yoke plate 19 and contacted magnetically and the first and the second voice coils 13 and 14, a second magnetic circuit composed of a second magnet 25 in magnetic contact with the third yoke plate 21 and the third voice coil 15, and dampers 16 and 24 to support the voice coil bobbin 12 movably to its axis direction. Thus, an electro-acoustic transducer to be able to convert heavy bass, to hold high linearity and to reproduce high-quality sound can be obtained.
