Problems solved by technology

Yantai Daming Electronic Technology Co., Ltd. developed a new type of small-sized surface-mounted quartz crystal resonator in 2012, and the invention patent number ZL2012200122170 solved this problem. However, due to the relative extension of the reed length, the rigidity of the reed will be reduced, resulting in a decrease in crystal stability.

Abstract

The invention relates to a reed, a quartz crystal resonator and a processing method, and belongs to the technical field of structures of reeds and resonators. The quartz crystal resonator comprises a left reed and a right reed which are respectively provided with two reverse extension arms, wherein the extension arm I of the left reed extends to the right side of a crystal and is connected with a right leading wire pin head of the crystal in spot welding mode, the extension arm II of the right reed extends to the left side of the crystal and is connected with a left leading wire pin head of the crystal in spot welding mode, and the extension arm I and the extension arm II are respectively vertical to horizontal planes of the left reed and the right reed after being rotated by 90 degrees respectively around the length directions. The reed, the quartz crystal resonator and the processing method have the advantages of being reasonable in structure design, simple and direct in processing technology, and not only good in elasticity but also strong in rigidity.

Description

technical field [0001] The invention relates to a reed, a quartz crystal resonator and a processing method, and belongs to the technical field of reed and resonator structures. Background technique [0002] The working principle of the quartz crystal resonator is a resonant device made of the inverse piezoelectric effect of the quartz crystal (silicon dioxide crystal). At present, quartz resonators have become an important part of the digital information society in the future, and their main market areas are communication, industrial, and civilian electronic equipment; Among such equipment, instruments, and electronic products, they are indispensable key components in today's electronic products. [0003] At present, surface mount and miniaturized products have become the development direction of electronic products. The miniaturization of crystals requires the size of the resonator cavity to be shortened, the length of the reed arms to be shortened, and the stress is not e...
