SUPPORT STRUCTURE FOR VIBRATOR

摘要

PURPOSE:To maintain the vibration of the vibrator in its initial state 83 it is. CONSTITUTION:The prismatic vibrator 20 is supported on a fixed frame body 35 with opposite support members 41 and 42 and opposite support members 33 and 34. Those respective support members 33 and 34 face each other at nodes 20a and 20b of vibration when the vibrator 20 vibrates in primary vibration mode, and also have their one-terminal sides coupled with the vibrator 20 to support it. The support members 33 and 34 are formed in the same L outward shape which is bent at one place on the X-Y plate in the figure. Then the opposite support members are arranged symmetrically about corresponding nodes 20a and 20b of the vibrator 20 and further in point symmetry about the center of the center 20c of gravity of the vibrator 20.
