振动片、振子、振荡器以及电子设备
摘要：
本发明提供振动片、振子、振荡器以及电子设备，通过蚀刻加工而得到的振动片具有：基部，具有缺口和连接部、第1部分以及第2部分，缺口和连接部沿着第1方向排列，第1部分沿着与第1方向交叉的方向排列在缺口和连接部的一侧，与连接部连接，第2部分沿着交叉的方向排列在缺口和连接部的另一侧，与连接部连接；以及振动臂，沿着与第1方向交叉的第2方向从第1部分突出，缺口具有：第1范围，具有被基部的主面的外缘夹着划定的第2方向上的宽度；第2范围，与第1范围相比，离连接部更远；以及第3范围，位于第1范围与第2范围之间，对于在第1方向上延伸的假想线与外缘所成的角，第3范围中的上述角比第1范围和第2范围中的上述角小。
摘要（英）：

The invention provides a vibrating plate, a vibrator, an oscillator and an electronic device. The vibrating plate obtained by etching processing comprises a base portion andvibrating arms. Thebase portion comprises a notch, a connecting portion, a first part and a second part. The notch and the connecting portionare arranged along a first direction. The first part is arranged on a side of the notch and the connecting portion along a direction crossed with the first direction, and the first part is connected with the connecting portion. The second part is arranged on the other side of the notch and the connecting portion along a direction crossed with the direction, and is connected with the connecting portion. The vibrating arms are protruding from the first part along a second direction which is crossed with thefirst direction. The notch is provided with a first range, a second range, and a third range. The first range is provided with width of the second direction designated by pressing an outer edge of a main surface of the base portion. Compared with the first range, the second range is farther from the connecting portion. The third range is disposed between the first range and the second range. For an angle between a phantom line extending on the first direction and the outer edge, the angle in the third range is smaller than the angle in the first range and the second range.
