Abstract

PURPOSE:To simplify the mass-production of coils and to reduce the effective mass of a vibration system by arranging two magnets with the same poles opposing mutually and then by allowing magnetic flux passing through opposite side of a magnet to reach collars of coils. CONSTITUTION:To the base end of cantilever 1, coils 31 and 32 wound around bobbins 41 and 42 of a magnetic body whose section is nearly in a H shape with their cores agreeing the axial direction of cantilever 1 and two magnetic 51 and 52 are arranged close to bobbins 41 and 42 while their magnetizing directions will be in parallel to cantilever 1 and the same poles are made to oppose each other, so that magnetic flux passing through the side opposite magnets 51 and 52 reaches collars of bobbins 41 and 42 of coils 31 and 32. Consequently, the mass-production of coils is simplified and the effective mass of the vibration system can be reduced.
