Glass pearl, shell and lead, the chip are arranged on bead, are connected with lead, and the shell covers in bead outer end,
The chip is set to the tuning fork chip architecture of upper end bifurcated, is cut using ST cut types, wafer surface attachment rotary electrode.
As further program of the utility model：The rotary electric extremely silver-coated electrode, the silver-coated electrode layer are right
Title is arranged at wafer surface.
As further program of the utility model：The rotary electrode is provided with electrode A and two electrode Bs, described
Electrode A is arranged at center wafer, forms class " y " shape along tuning fork bifurcated mouth, and described two electrode Bs are respectively arranged at chip length end two
Side edge.
As further program of the utility model：The tuning fork shape chip length dimension is 4.22mm, and width dimensions are
1mm, thickness are 0.33mm, and tuning fork end length dimension is 2.6mm, and tuning fork end width dimensions are 0.4mm.
Compared with prior art, the beneficial effects of the utility model are：This utility model product is by using unique ST
Cut type, retains traditional tuning fork structure, promotes which to allow the smooth starting of oscillation of chip using rotary electrode, and distortion formula mode of vibration is maximum
Conventional the be beyond one's reach frequency of tuning fork crystal is realized, is greatly reduced using imported product and the cost using frequency multiplier circuit.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only this utility model a part of embodiment, rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
Fig. 1～3 are referred to, in embodiment of the present utility model, a kind of altofrequency cylindrulite of frequency for 307.2KHZ, including
Chip 1, bead 2, shell 4 and lead 3, wherein chip 1 are weldingly fixed on bead 2 by solder joint 5 with lead 3, glass
2 outer end of pearl is provided with kovar ring 6, and shell 4 covers in 2 outer end of bead and internal wafer 1 is protected, wherein the structure of chip 1
For the tuning fork chip architecture of upper end bifurcated, tuning fork chip architecture is 4.22mm according to length dimension, and width dimensions are 1mm, thickness
For 0.33mm, tuning fork end length dimension is 2.6mm, and tuning fork end width dimensions are defined for the size of 0.4mm, and chip 1 is adopted
Cut with ST cut types, and in 1 surface attachment rotary electrode 110 of chip, the rotary electrode 110 is silver coating material electricity
Pole, silver-coated electrode layer are symmetricly set in wafer surface, and side is provided with side silver-coated electrode connects double-face electrode, wherein the rotation
Formula electrode is provided with electrode A 111 and two electrode Bs 112, and the electrode A 111 is arranged at center wafer, along the tuning fork bifurcated degree of lip-rounding
Into class " y " shape, upper end connecting side right side of face face top silver-coated electrode on the right side of " y " shape, " y " lower end exit connection left surface bottom
Silver-coated electrode, described two electrode Bs 112 are respectively arranged at chip length end both sides edge, right electrodes B112 and right flank bottom
Silver-coated electrode connects, and left electrodes B112 are connected with left surface top silver-coated electrode, by ST cut types and the knot of rotary electrode
Structure is designed so that cylindrulite frequency is substantially improved, 1 dimension limitation of chip, realizes that the frequency to 307.2KHZ determines.
Working method principle of the present utility model is：Chip 1 is carried out ST cut type cuttings by this utility model product, and according to
Required dimensional requirement is defined and 1 surface of chip is provided with rotary electrode 110 so that the distortion type vibration of ST cut types
Cooperate with rotary electrode, when 1 surface electrode A111 of chip and electrode B 112 are powered, quartz plate surface just generates should
Power, as chip 1 is ST cut types, so when being stressed, tuning fork two-arm produces the vibration of distortion formula, so as to starting of oscillation.Distortion formula
Mode of vibration farthest realizes tuning fork crystal and is routinely beyond one's reach altofrequency.
