(Note 1)
The relationship between the size of the resonator
and the resonant frequency is described as follows.
For example, the frequency doubles if the thickness
doubles, when thickness vibration is used.
The following relationship is obtained when the
length of the resonators is ℓ, the resonance
frequency is Fr, the speed of sound waves travelling
through piezoelectric ceramics, and the wavelength
is λ.
As seen in the above formula, the frequency
constant determines the size of the resonator.

Notes
Fr . ℓ = Const.
(frequency constant, Fr . t for the thickness)
λ = 2 ℓ
C = Fr . λ = 2Fr . ℓ
