Abstract

PURPOSE:To prevent resonance and to evade deterioration in frequency characteristics accompanied by the resonance, by connecting the bottom parts of magnetic circuit units by a reinforcement member made of a thin plate. CONSTITUTION:A thin disk 16 is provided as a reinforcement member to the bottom part of a magnetic circuit unit 5, and through screw hole 16' made at four positions of its circumferential edge part, magnetic units 5A-5D are coupled by screwing, thus preventing the outward vibration of each unit, i.e., resonance. Consequently, the magnetic circuits 5A-5D are united with regard to vibration and the axial line of another unit is restricted, so deterioration in frequency characteristics accompanied by the resonance is evaded. The magnetic circuit unit 5C and 5D are not shown in figure.
