Description

Technical Field

[0001] The utility model relates to the field of crystal resonators, and more specifically, to a crystal oscillator assembly. Background Art

[0002] The crystal resonator is made based on the principle that when the frequency of the electrical signal is equal to the natural frequency of the quartz crystal plate, the quartz crystal plate will produce resonance.
