Description
;1;one
Изобретение относитс к области приборостроени и может быть применено в технической акустике и других област х техники, иснользующих механические колебани твердых тел.The invention relates to the field of instrumentation and can be applied in technical acoustics and other areas of technology that use mechanical vibrations of solids.
Известные способы плавной обратимой перестройки частоты упругого резонанса колебаний твердого тела используют изменение геометрии колеблющегос тела и не обеспечивают достаточной точности и ширины диапазона перестройки частоты.Known methods of smooth reversible frequency tuning of the elastic resonance of oscillations of a solid body use a change in the geometry of the oscillating body and do not provide sufficient accuracy and width of the frequency tuning range.
Предложенный способ отличаетс от известных тем, что в качестве колеблющегос твердого тела используют монокристалл гематита , помещают его в посто нное по вел.ичине магнитное поле, направление которого относительно монокристалла -измен ют.The proposed method differs from the known ones in that a hematite single crystal is used as an oscillating solid and placed in a constant magnetic field whose direction relative to the single crystal is changed.
Этот способ позвол ет расширить диапазон изменени частоты упругого резонанса.This method allows the frequency range of the elastic resonance to be expanded.
Способ реализуетс следующим образом. The method is implemented as follows.
Молокристалл гематита, колебани в котором возбуждены по всему объему, например, при помощи катушки помещают в посто нное по величине магнитное поле. Поворачива затем кристалл относительно направлени магнитных силовых линий достигают необходимой перестройки частоты упругого резонанса монокристалла.The hematite milk crystal, oscillations in which are excited throughout the whole volume, for example, is placed in a constant magnetic field by means of a coil. Then the crystal is rotated relative to the direction of the magnetic field lines to achieve the necessary frequency tuning of the elastic resonance of the single crystal.
