Quartz oscillating plate

A quartz oscillating plate comprising a substrate, a first side-electrode, a second side-electrode, a first surface electrode, and a first connection member, wherein said substrate has a notch along a lateral side of said substrate;

• said first and second side-electrodes are respectively disposed at two corners of a top side of said substrate with said notch sandwiched in between;
• said first surface electrode is disposed on said top side besides said first side-electrode, said notch, and said second side-electrode;
• said first connection member is disposed on said top side connecting said first surface electrode and said first side-electrode;
• wherein said notch is surrounded by a first inner side, a third inner side opposing said first inner side, and a second inner side between said first and third inner sides;
• said notch defining a length of a transmission path which includes a summation of lengths of said first, said second, and said third inner sides, a first included angle between said first inner side and said second inner side is greater than 90 degrees and is smaller than 160 degrees;
• a second included angle between said second inner side and said third inner side is greater than 90 degrees and is smaller than 160 degrees;
• wherein said notch has a depth of 10-160 μm corresponding to the first included angle and the second included angle;
• whereby said transmission path is selectively chosen as a function of the lengths of said first inner side, second inner side and third inner side and said first and second included angles.
