Wafer is set to the tuning fork chip architecture of upper end bifurcated, uses the cutting of ST cut type, wafer surface attachment rotary electrode.
As the further scheme of the present invention: described rotary electric extremely silver-coated electrode, described silver-coated electrode layer symmetry sets
It is placed in wafer surface.
As the further scheme of the present invention: described rotary electrode is provided with electrode A and two electrode B, described electrode A
Being arranged at center wafer, along tuning fork bifurcated interruption-forming class " y " shape, said two electrode B is respectively arranged at limit, wafer long end both sides
Edge.
As the further scheme of the present invention: described tuning fork shape wafer length dimension is 4.22mm, and width dimensions is 1mm,
Gauge is 0.33mm, and tuning fork end length dimension is 2.6mm, and tuning fork end width dimensions is 0.4mm.
Compared with prior art, the invention has the beneficial effects as follows: product of the present invention, by using unique ST cut type, retains

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Referring to Fig. 1～3, in embodiments of the invention, a kind of frequency is the altofrequency cylindrulite of 307.2KHZ, including wafer
1, bead 2, shell 4 and lead-in wire 3, wherein wafer 1 is weldingly fixed on bead 2, outside bead 2 by solder joint 5 with lead-in wire 3
End is provided with kovar ring 6, and shell 4 covers in bead 2 outer end and protects internal wafer 1, and wherein the structure of wafer 1 is upper end
The tuning fork chip architecture of bifurcated, tuning fork chip architecture is 4.22mm according to length dimension, and width dimensions is 1mm, and gauge is
0.33mm, tuning fork end length dimension is 2.6mm, and tuning fork end width dimensions is that the size of 0.4mm is defined, and wafer 1 uses
ST cut type is cut, and at wafer 1 surface attachment rotary electrode 110, this rotary electrode 110 is silver coating material electrode,
Silver-coated electrode layer is symmetricly set in wafer surface, and side is provided with side silver-coated electrode makes double-face electrode connect, and wherein this is rotary
Electrode is provided with electrode A 111 and two electrode B 112, and described electrode A 111 is arranged at center wafer, along tuning fork bifurcated interruption-forming
Class " y " shape, right flank top, connection side, upper end silver-coated electrode on the right side of " y " shape, " y " exit, lower end connects the plating of left surface bottom
Silver electrode, said two electrode B 112 is respectively arranged at edge, wafer long end both sides, and right electrodes B112 is plated with right flank bottom
Silver electrode connects, and left electrodes B112 is connected with left surface top silver-coated electrode, by the structure of ST cut type Yu rotary electrode
Design so that cylindrulite frequency is substantially improved, wafer 1 dimension limitation, it is achieved determine the frequency of 307.2KHZ.
The working method principle of the present invention is: wafer 1 is carried out ST cut type cutting by product of the present invention, and according to required chi
Very little requirement is defined and has rotary electrode 110 in wafer 1 surface configuration so that the distortion type of ST cut type vibrates with rotary
Electrode cooperates, and when wafer 1 surface electrode A111 and electrode B 112 are energized, quartz plate surface just creates stress, due to
Wafer 1 is ST cut type, so when being stressed, tuning fork two-arm produces distortion formula and vibrates, thus starting of oscillation.Distortion formula mode of vibration
Farthest achieve tuning fork crystal routine to be beyond one's reach altofrequency.
