Quartz resonators with low phase noise and anti-vibration quartz crystals

Abstract

The invention relates to a quartz resonator, and discloses a quartz resonator comprising a low-phase-noise shock resistance quartz crystal wafer. The quartz resonator comprises the quartz crystal wafer (1), and a main electrode (6) is connected to the quartz crystal wafer (1); a first secondary electrode (51) and a first conductive electrode (71) are connected to the top face (11) of the quartz crystal wafer (1), and a second secondary electrode (52) and a second conductive electrode (72) are connected to the bottom face (12) of the quartz crystal wafer (1); the projection of the first secondary electrode (51) on the bottom face (12) is in point symmetry with the projection of the second secondary electrode (52) on the bottom face (12), and the projection of the first conductive electrode (71) on the bottom face (12) is in point symmetry with the projection of the second conductive electrode (72) on the bottom face (12). The quartz resonator is simple in structure and convenient to use, and improves structural stability and external force resistance capacity due to the fact that the quartz crystal wafer with the small diameter is adopted.

Description

technical field [0001] The invention relates to an electronic original device, in particular to a quartz resonator containing a low-phase-noise anti-vibration quartz wafer. Background technique [0002] figure 2 It is a schematic structural diagram of an existing quartz wafer, in which the secondary electrodes of the existing quartz wafer are arranged parallel to the vertical plane (z-axis in the prior art). In the actual working process, such as in the vibration process, the quartz wafer is easily affected by external forces. The superposition of the above external force and the radial support force of the bracket on the wafer will affect the vibration of the wafer, thus making the operation of the quartz resonator unstable. Contents of the invention [0003] The object of the present invention is to provide a quartz resonator containing a low-phase-noise anti-vibration quartz wafer in order to overcome the disadvantages of the background technology.

Problems solved by technology

In the actual working process, such as in the vibration process, the quartz wafer is susceptible to external forces. The superposition of the above external force and the radial support force of the bracket on the wafer will affect the vibration of the wafer, thus making the work of the quartz resonator unstable.
