Patent number: 9871470Abstract: The piezoelectric vibrator element is miniaturized, and at the same time, the vibration leakage is suppressed. The piezoelectric vibrator element is formed so that the total length L1 of the piezoelectric vibrator element, the length L2 of the base, the width L3 of the connection part, the length L4 of the support arm part fulfill all of the following conditions A through C, Condition A: 0.1?L2/L1?0.2, Condition B: 0.4?L3/L2?0.6, Condition C: L4/L1?0.7. While the miniaturization is realized by shortening the base due to the condition A, the distance via the base can be elongated due to the condition B. Further, by increasing the length of the support arm parts due to the condition C, it is possible to increase the total mass of the path transmitting the vibration to absorb the vibration to thereby further suppress the vibration leakage.Type: GrantFiled: February 13, 2017Date of Patent: January 16, 2018Assignee: SII CRYSTAL TECHNOLOGY INC.Inventor: Naoya Ichimura
