There are many consumer products that claim 4%t&/)a* of dance'), and whip-cut crystal resonators have been used in these products. However, recently, various consumer devices have been made smaller, and whip-cut crystal resonators have also been required to be made smaller.
n), making it difficult to downsize, and at the same time, downsizing causes C
The reality is that the cost of construction becomes more expensive. When using a whip-cut quartz crystal #1 as a watch crystal oscillator, it is necessary to make it considerably smaller, but when compared with a tuning fork type bent quartz crystal oscillator, it is completely satisfactory in terms of size. Therefore, by applying IC technology, the method of forming an image sensor using skin photorin graph-IK was applied to the manufacture of a transducer, and as a result, it was possible to provide a very small transducer. For example, it has been applied to GT-cut crystal resonators with excellent temperature characteristics that allow the thickness of the camera element to be made extremely thin, making it possible to create extremely compact devices.However, the conventional support structure However, it had the disadvantage of poor workability and poor needle impact resistance.Figures 1 (A) and (B)
The FiGT cut crystal resonator 1 is mounted on a conventional support pedestal 4, and the plan view 11fI (4 As shown in the side view of FIG. 1(B), the crystal resonator 1 is placed on both ends of the support pedestal 4 at 1s7.80 planes, and the ends 5 and 6 of the resonator are glued or soldered. 1 is supported and fixed.
