Abstract

PURPOSE:To attenuate the external mechanical oscillation variably and to change the resonant frequency of oscillator, by magnetizing a part of the oscillation attenuating alloy constituted at a part of the oscillation member. CONSTITUTION:The diapason 4 constituted with the oscillation attenuating alloy made of Al, Cr, Fe and accompanied impurity is fitted to the resonation box 5 and the magnetizing unit 6 is provided near the diapason 4. With this constitution, the magnetization of the diapason 4 can change the oscillation mode and the resonant frequency by means of the unit 6.
