Abstract

PURPOSE:To enable to obtain high Q value such as 200,000-300,000 by eliminating loss of oscillation energy, by providing the support resonated with the frequency equal to the resonant frequency of the coupled diapason type crystal oscillator at the base of the coupled tuning fork type crystal oscillator. CONSTITUTION:The coupled tuning fork type crystal oscillator consists of the main body 6, support 7 for the main body 6, bonding part 8 for the lead, boundary 9 between the support 7 and the bonding part 8, and the boundary 10 between the main body 6 and the support 7. Further, the main body 6, support 7 and bonding part 8 are cut out incorporatedly from the crystal ore, and the resonant frequency of the support 7 is equally selected as the resonant frequency of the main body 6. With this constitution, the oscillating displacement of the boundary 9 is zero, and the oscillating displacement of the bonding part 8 is almost zero. Accordingly, even if the bonding part 8 is soldered with leads, no oscillation energy is lost and high Q value such as 200,000-300,000 is obtained, allowing the usage for electronic watches.
