This paper describes the frequency temperature characteristics and electrical characteristics of a new shape X cut longitudinal quartz crystal resonator. According to miniaturization of consumer products and communication equipments, miniaturization of a quartz crystal resonator which is used for them is also required. Simultaneously, automatic assembly lines by use of robots are positively adopted in manufacturing processes. Under these circumstances, a surface mounting type quartz crystal resonator is required and to achieve this requisite, a new design of the resonator including a supporting method is naturally needed. This paper proposes a new shape longitudinal quartz crystal resonator, and analyses and examines frequency temperature characteristics and electrical ones of the resonator. In analysis procedure, first, equation of motion for a new shape longitudinal quartz crystal resonator consisting of a vibrational portion and supporting portions is derived by an energy method. From the obtained equation of motion, a frequency equation is calculated. Next, frequency temperature characteristics and electrical ones of the resonator are analysed, and the analysed results are compared with the experimental values. Consequently, it is shown that both results agree well.
