Japan, Feb. 27 -- SWATCH GROUP RESEARCH & DEVELOPMENT LTD has got intellectual property rights for 'BALANCE SPRING TYPE PIEZOELECTRIC RESONATOR ESPECIALLY FOR ROTATION MOTOR FOR TIMER.' Other related details are as follows:
Application Number: JP,2023-206695
Category (FI): G04C3/12@Z
Stage: PROBLEM TO BE SOLVED: To provide a piezoelectric resonator capable of withstanding a high electromagnetic field while maintaining low power consumption and volume.SOLUTION: The present invention relates to a piezoelectric resonator 1 for a rotary piezoelectric motor. The resonator comprises a fixed base 3, and an oscillating weight 2 extending around a longitudinal axis. The oscillating weight has an inertial block 4, preferably two opposite inertial blocks. The piezoelectric resonator comprises a flexible blade guide connecting the oscillating weight to the base, and can oscillate the oscillating weight around a rotation center in a pendulum motion manner. The flexible blade guide comprises: a first flexible blade 6 connected to the base and/or the oscillating weight, and allows the oscillating weight to be displaced relative to the base; and a helical spring 5 connected to the base and/or the oscillating weight. The helical spring comprises, at least in part, an electrically actuatable piezoelectric material, which deforms the helical spring and causes the oscillating weight to oscillate.SELECTED DRAWING: Figure 1 (Grant)
