Abstract

PURPOSE:To decrease the mechanical impedance and to lower the resonance frequency, by forming an oscillator with a piezoelectric element forming bimorph. CONSTITUTION:The oscillating part of an element 8 forming bimorph is formed so that it is a series of band shape. The said oscillation part is formed as a series of band shape as shown in figure, allowing to lower the mechanical impedance of the oscillation system and to decrease the resonance frequency.
