| titleOfInvention | A kind of quartz crystal resonator and its manufacturing method |
| abstract | The invention relates to a quartz crystal resonator, comprising a vibrating part and a base part, the vibrating part is in the shape of a tuning fork, the vibrating part includes a first vibrating arm and a second vibrating arm, and the junction of the first vibrating arm and the second vibrating arm is connected to the base; Both the ends of the first vibrating arm and the second vibrating arm are provided with frequency modulation parts, and through holes are symmetrically arranged on the first vibrating arm and the second vibrating arm, and the through holes are axially arranged on the first vibrating arm and the second vibrating arm Array distribution; excitation electrodes are arranged on the first vibrating arm and the second vibrating arm. Compared with the prior art, the structure of the present invention can generate more electric fields in the transverse and horizontal directions, the electric field efficiency is high, and the piezoelectric efficiency is better, so that the resonator has an excellent quality factor Q value; secondly, the structure of the square hole is simple Moreover, the rigidity is strong, the manufacturing process is simple, and the requirement for etching precision is low. |
