Abstract
A quartz oscillating plate comprises a substrate having a notch. Two sides of the notch respectively have a first side-electrode and a second side-electrode. The first side-electrode receives an external signal. The external signal is transmitted along the perimeter of the substrate. The notch of the substrate can increase the length of the transmission path of oscillation energy. The present invention can improve the Q value of the quartz oscillator using the quartz oscillating plate and optimize the performance of the products using the quartz oscillator.
