METHOD FOR MAINTAINING OSCILLATIONS OF A VIBRATING DEVICE AND VIBRATING DEVICE USING SAME

摘要

A kind of vibratory equipment of the present invention in relation to method for maintaining vibratory equipment to vibrate and implementation this method. The vibration device is designed as being equipped with unit carrying close to main body, if clock and watch, including shell, moving mass body transmit vibration in said case, coil (L) is electromagnetically coupled to the moveable quality, make the exciting circuit (L of its vibration and a coil. The method is characterized in that the alternately polarity of pulse (21,22) and specific duration (cycle T PULSE) is kept to essentially coincide, the terminal (L) of the coil generated with the voltage (Uind, VB12) of movement caused by extreme value is generated. Does each keep the end of pulse (21,22) to generate specific non-variable time interval (T to-pulse? from) calculate the voltage moved caused by average cross, the time interval (T from-pulse?) it is by the vibration device of the vibration of instantaneous self-resonant frequency, so that the pulse (21,22) that adaptive frequency is safeguarded is generated and obtains to reaching the average level to intersect at maintenance pulse (21,22) by the voltage caused by the movement.
