Abstract

PURPOSE:To obtain a longitudinal crystal resonator with a less vibration leakage, and besides, to obtain a cut angle to give a zero temperature coefficent by enclosing the resonator by a curved part coupled from a vibrating part, and coupling the curved part with a frame opposite to the mount side, and besides, forming a Z plate in the specified range of a angle as cosidering X axis to be an axis of rotation. CONSTITUTION:With regard to the vibration leakage, the vibrating part 2 and the curved part 5 are formed into one body through a bridge part 4 by an etching method, and its end part is connected to the frame 6. Then, one end of the curved part 5 is connected to the frame 6, and the other end is constructed so as to be able to vibrate freely as surrounding the vibrating part 2. Therefore, since if the mass of the frame 6 is made large, energy can be confined in the top tip part of a supporting part 3, the longitudinal crystal resonator entirely free of the vibration leakage can be obtained even if it is fixed at the mount part 7. Besides, since a vertex angle Tp can be changed according to the cut angle theta, it is chosen according to a requested specification. Then, frequency variation is made small especially in the range of -10 deg.C-+60 deg.C by choosing the cut angle in the range of -2 degrees-+4 degrees.
