CHIP TYPE PIEZO-RESONANCER AND RESONANCE WAVE CONTROL METHOD OF THEM

摘要

PURPOSE: The chip type piezo-resonancer and resonance wave control method of them is provided to improve the accuracy of electrostatic capacity and resonance wave. CONSTITUTION: The chip type piezo-resonancer comprises: a dielectric substrate, an external electrode. The dielectric substrate pilled up the top and bottom of a piezo-substrate. The external electrode located on the pilled body. The plural external electrodes a first surface and a second surface opposed each other from external around of a first dielectric substrate.
