Abstract
PURPOSE:To reduce generation of split vibration by arranging magnets so that magnetic poles may be inverted successively vertically and horizontally and by providing conductors on a diaphragm vertically and horizontally so that the electomagnetic force received by each part of the conductor may be in the same direction when a current is flowed to the conductor. CONSTITUTION:Upper magnet plate 6 and lower magnet plate 7 where plural small magnets are provided are arranged oppositely to the upper face and the lower face of diaphragm 5 provided with conductors respectively. In magnet plate 7, small magnets 8... are arranged into checkers at a regular interval through space on yoke plate 9 consisting of a ferromagnetic material, and the magnetization direction of small magnets 8... is vertical to yoke plate 9, and further, magnetic poles on the surface of small magnets 8... are inverted successively vertically and horizontally. Yoke plate 9 is provided with sound holes similarly to magnet plate 6. Conductors 10 are arranged on the surface of diaphragm 5. Then, these conductors 10 are so caused to run that the position corresponding to the gap of small magnets 8... may be vertical and horizontal successively and the electromagnetic force dependent upon the magmetic field formed by small magnets 8... may be in the same direction in each part of conductors 10.
