Abstract
PURPOSE:To reduce driving force distortion by winding a coil length per each width unit of a voice coil so that it is increased gradually as it goes on from the center part to both the ends, over the winding width of the voice coil. CONSTITUTION:The winding width of the voice coil 10 is made wider than the thickness of a plate magnetic pole 4. As for this voice coil 10, the number of winding is increased in the winding width direction as it approaches to both end parts, by grading the number of winding of the voice coil. That is to say, the voice coil length per each winding width in the voice coil winding length is increased in order as it goes on from the center part to both ends. According to such a constitution, the driving force distortion is reduced by compensating the unequality of void magnetic flux density distribution of the magnetic circuit.
