Abstract

A tuning fork type quartz crystal resonator using a coupling between the fundamental flexural and fundamental torsional modes of vibration. The resonator has a base and two tuning fork arms extending from the base. The length of the base is larger than that of the tuning fork arms. The base has a narrow width portion effective to lower the vibrating displacements of the base end according to the torsional mode.
