Abstract

PURPOSE:To obtain a stable vibrator with restraining the secondary vibration low without increasing the resonance resistance of fundamental vibration by providing an electrode for restraining the secondary vibration in the vibration arm, which stands vertically from the vibrator horizontal base part. additionally to an electrode for driving. CONSTITUTION:Two vibration arm parts 2 are so formed that they may stand vertically on vibrator horizontal base part 1, and driving electrode 3 is fitted from horizontal base part 1 across arm parts 2. At this time, arm parts 2 are so arranged that the polarity may be opposite in adjacent side faces and be equal in opposite side faces. Further, electrode 4 for restraining the secondary vibration different in polarity is formed at the tip of arm parts 2 additionally to electrode 3. Electrode 4 is so selected that it may be different in polarity from electrode 3, which is provided in the same side face, in two or more side faces, at least, of four side faces of arm parts 2. Thus, the resonance resistance of the secondary mode becomes infinite, and the secondary vibration is not generated.
